  • Plagiarism

    Even though most student plagiarism is probably unintentional, it is in students’ best interests to become aware that failing to give credit where it is due can have serious consequences. For example, at Butte College, a student caught in even one act of academic dishonesty may face one or more of the following actions by his instructor or the college:

    • Receive a failing grade on the assignment
    • Receive a failing grade in the course
    • Receive a formal reprimand
    • Be suspended
    • Be expelled

    My paraphrasing is plagiarized?
    Of course, phrases used unchanged from the source should appear in quotation marks with a citation. But even paraphrasing must be attributed to the source whence it came, since it represents the ideas and conclusions of another person. Furthermore, your paraphrasing should address not only the words but the form, or structure, of the statement. The example that follows rewords (uses synonyms) but does not restructure the original statement:

    Original:
    To study the challenge of increasing the food supply, reducing pollution, and encouraging economic growth, geographers must ask where and why a region’s population is distributed as it is. Therefore, our study of human geography begins with a study of population (Rubenstein 37).

    Inadequately paraphrased (word substitution only) and uncited:
    To increase food supplies, ensure cleaner air and water, and promote a strong economy, researchers must understand where in a region people choose to live and why. So human geography researchers start by studying populations.

    This writer reworded a two-sentence quote. That makes it his, right? Wrong. Word substitution does not make a sentence, much less an idea, yours. Even if it were attributed to the author, this rewording is not enough; paraphrasing requires that you change the sentence structure as well as the words. Either quote the passage directly, or
    substantially change the original by incorporating the idea the sentences represent into your own claim:

    Adequately, substantially paraphrased and cited:
    As Rubenstein points out, distribution studies like the ones mentioned above are at the heart of human geography; they are an essential first step in planning and controlling development (37).

    Perhaps the best way to avoid the error of inadequate paraphrasing is to know clearly what your own thesis is. Then, before using any source, ask yourself, “Does this idea support my thesis? How?” This, after all, is the only reason to use any material in your paper. If your thesis is unclear in your own mind, you are more likely to lean too heavily on the statements and ideas of others. However, the ideas you find in your sources may not replace your own well thought-out thesis.

    Copy & paste is plagiarism?
    Copy & paste plagiarism occurs when a student selects and copies material from Internet sources and then pastes it directly into a draft paper without proper attribution. Copy & paste plagiarism may be partly a result of middle school and high school instruction that is unclear or lax about plagiarism issues. In technology-rich U.S. classrooms, students are routinely taught how to copy & paste their research from Internet sources into word processing documents. Unfortunately, instruction and follow-up in how to properly attribute this borrowed material tends to be sparse. The fact is, pictures and text (like music files) posted on the Internet are the intellectual property of their creators. If the authors make their material available for your use, you must give them credit for creating it. If you do not, you are stealing.

    How will my instructor know?
    If you imagine your instructor will not know that you have plagiarized, imagine it at your own risk. Some schools subscribe to anti-plagiarism sites that compare submitted papers to vast online databases very quickly and return search results listing “hits” on phrases found to be unoriginal. Some instructors use other methods of searching online for suspicious phrases in order to locate source material for work they suspect may be plagiarized.

    College instructors read hundreds of pages of published works every year. They know what is being written about their subject areas. At the same time, they read hundreds of pages of student-written papers. They know what student writing looks like. Writers, student or otherwise, do not usually stray far from their typical vocabulary and sentence structure, so if an instructor finds a phrase in your paper that does not “read” like the rest of the paper, he or she may become suspicious.

    Why cite?
    If you need reasons to cite beyond the mere avoidance of disciplinary consequences, consider the following:

    • Citing is honest. It is the right thing to do.
    • Citing allows a reader interested in your topic to follow up by accessing your sources and reading more. (Hey, it could happen!)
    • Citing shows off your research expertise-how deeply you read, how long you spent in the library stacks, how many different kinds of sources (books, journals, databases, and websites) you waded through.

    How can I avoid plagiarism?
    From the earliest stages of research, cultivate work habits that make accidental or lazy plagiarism less likely:

    • Be ready to take notes while you research. Distinguish between direct quotes and your own summaries. For example, use quotation marks or a different color pen for direct quotes, so you don’t have to guess later whether the words were yours or another author’s. For every source you read, note the author, title, and publication information before you start taking notes. This way you will not be tempted to gloss over a citation just because it is difficult to retrace your steps.
    • If you are reading an online source, write down the complete Internet address of the page you are reading right away (before you lose the page) so that you can go back later for bibliographic information. Look at the address carefully; you may have followed links off the website you originally accessed and be on an entirely different site. Many online documents posted on websites (rather than in online journals, for example) are not clearly attributed to an author in a byline. However, even if a website does not name the author in a conspicuous place, it may do so elsewhere–at the very bottom/end of the document, for example, or in another place on the website. Try clicking About Us to find the author. (At any rate, you should look in About Us for information about the site’s sponsor, which you need to include in Works Cited. The site sponsor may be the only author you find; you will cite it as an “institutional” author.) Even an anonymous Web source needs attribution to the website sponsor.

      Of course, instead of writing the above notes longhand you could copy & paste into a “Notes” document for later use; just make sure you copy & paste the address and attribution information, too, and not directly into your research paper
    • Try searching online for excerpts of your own writing. Search using quotation marks around some of your key sentences or phrases; the search engine will search for the exact phrase rather than all the individual words in the phrase. If you get “hits” suggesting plagiarism, even unintentional plagiarism, follow the links to the source material so that you can properly attribute these words or ideas to their authors.
    • Early in the semester, ask your instructors to discuss plagiarism and their policies regarding student plagiarism. Some instructors will allow rewrites after a first offense, for example, though many will not. And most instructors will report even a first offense to the appropriate dean.
    • Be aware of the boundary between your own ideas and the ideas of other people. Do your own thinking. Make your own connections. Reach your own conclusions. There really is no substitute for this process. No one else but you can bring your particular background and experience to bear on a topic, and your paper should reflect that.

  • Inductive versus Deductive

    As a media student, you are likely to come across two primary research methods: inductive and deductive research. Both approaches are important in the field of media research and have their own unique advantages and disadvantages. In this essay, we will explore these two methods of research, along with some examples to help you understand the differences between the two.

    Inductive research is a type of research that involves starting with specific observations or data and then moving to broader generalizations and theories (Theories, Models and Concepts) It is a bottom-up approach to research that focuses on identifying patterns and themes in the data to draw conclusions. Inductive research is useful when the research problem is new, and there is no existing theoretical framework to guide the study. This method is commonly used in qualitative research methods like ethnography, case studies, and grounded theory.

    An example of inductive research in media studies would be a study of how social media has changed the way people interact with news. The researcher would start by collecting data from social media platforms and observing how people engage with news content. From this data, the researcher could identify patterns and themes, such as the rise of fake news or the tendency for people to rely on social media as their primary news source. Based on these observations, the researcher could then develop a theory about how social media has transformed the way people consume and interact with news.

    On the other hand, deductive research involves starting with a theory or hypothesis (Developing a Hypothesis: A Guide for Researchers) and then testing it through observations and data. It is a top-down approach to research that begins with a general theory and seeks to prove or disprove it through empirical evidence. Deductive research is useful when there is an existing theory or hypothesis to guide the study. This method is commonly used in quantitative research methods like surveys and experiments.

    An example of deductive research in media studies would be a study of the impact of violent media on aggression. The researcher would start with a theory that exposure to violent media leads to an increase in aggressive behavior. The researcher would then test this theory through observations, such as measuring the aggression of participants who have been exposed to violent media versus those who have not. Based on the results of the study, the researcher could either confirm or reject the theory.

    Both inductive and deductive research are important in the field of media studies. Inductive research is useful when there is no existing theoretical framework, and the research problem is new. Deductive research is useful when there is an existing theory or hypothesis to guide the study. By understanding the differences between these two methods of research and their applications, you can choose the most appropriate research method for your media research project.

  • First Step

    As a student, you may be required to conduct research for a project, paper, or presentation. Research is a vital skill that can help you understand a topic more deeply, develop critical thinking skills, and support your arguments with evidence. Here are some basics of research that every student should know.

    What is research?

    Research is the systematic investigation of a topic to establish facts, draw conclusions, or expand knowledge. It involves collecting and analyzing information from a variety of sources to gain a deeper understanding of a subject.

    Types of research

    There are several types of research methods that you can use. Here are the three most common types:

    1. Quantitative research involves collecting numerical data and analyzing it using statistical methods. This type of research is often used to test hypotheses or measure the effects of specific interventions or treatments.

    2. Qualitative research involves collecting non-numerical data, such as observations, interviews, or open-ended survey responses. This type of research is often used to explore complex social or psychological phenomena and to gain an in-depth understanding of a topic.

    3. Mixed methods research involves using both quantitative and qualitative methods to answer research questions. This type of research can provide a more comprehensive understanding of a topic by combining the strengths of both quantitative and qualitative data.

    Steps of research

    Research typically involves the following steps:

    1. Choose a topic: Select a topic that interests you and is appropriate for your assignment or project.
    2. Develop a research question: Identify a question that you want to answer through your research.
    3. Select a research method: Choose a research method that is appropriate for your research question and topic.
    4. Collect data: Collect information using the chosen research method. This may involve conducting surveys, interviews, experiments, or observations, or collecting data from secondary sources such as books, articles, government reports, or academic journals.
    5. Analyze data: Examine your research data to draw conclusions and develop your argume
    6. Present findings: Share your research and conclusions with others through a paper, presentation, or other format.

    Tips for successful research

    Here are some tips to help you conduct successful research:

    • Start early: Research can be time-consuming, so give yourself plenty of time to complete your project.
    • Use multiple sources: Draw information from a variety of sources to get a comprehensive understanding of your topic.
    • Evaluate sources: Use critical thinking skills to evaluate the accuracy, reliability, and relevance of your sources.
    • Take notes: Keep track of your sources and take notes on key information as you conduct research.
    • Organize your research: Develop an outline or organizational structure to help you keep track of your research and stay on track.
    • Use AI to brainstorm, get a broader insight in your topic, and what possible gaps of problems might be. Use it not to execute and completely write your final work

  • Result Presentation (Chapter E1-E3)

    Chapter E1-E3 Matthews and Ross

    Presenting research results effectively is crucial for communicating findings, influencing decision-making, and advancing knowledge across various domains. The approach to presenting these results can vary significantly depending on the setting, audience, and purpose. This essay will explore the nuances of presenting research results in different contexts, including presentations, articles, dissertations, and business reports.

    Presentations

    Research presentations are dynamic and interactive ways to share findings with an audience. They come in various formats, each suited to different contexts and objectives.

    Oral Presentations

    Oral presentations are common in academic conferences, seminars, and professional meetings. These typically involve a speaker delivering their findings to an audience, often supported by visual aids such as slides. The key to an effective oral presentation is clarity, conciseness, and engagement[1].

    When preparing an oral presentation:

    1. Structure your content logically, starting with an introduction that outlines your research question and its significance.
    2. Present your methodology and findings clearly, using visuals to illustrate complex data.
    3. Conclude with a summary of key points and implications of your research.
    4. Prepare for a Q&A session, anticipating potential questions from the audience.

    Poster Presentations

    Poster presentations are popular at academic conferences, allowing researchers to present their work visually and engage in one-on-one discussions with interested attendees. A well-designed poster should be visually appealing and convey the essence of the research at a glance[1].

    Tips for effective poster presentations:

    • Use a clear, logical layout with distinct sections (introduction, methods, results, conclusions).
    • Incorporate eye-catching visuals such as graphs, charts, and images.
    • Keep text concise and use bullet points where appropriate.
    • Be prepared to give a brief oral summary to viewers.

    Online/Webinar Presentations

    With the rise of remote work and virtual conferences, online presentations have become increasingly common. These presentations require additional considerations:

    • Ensure your audio and video quality are optimal.
    • Use engaging visuals to maintain audience attention.
    • Incorporate interactive elements like polls or Q&A sessions to boost engagement.
    • Practice your delivery to account for the lack of in-person cues.

    Articles

    Research articles are the backbone of academic publishing, providing a detailed account of research methodologies, findings, and implications. They typically follow a structured format:

    1. Abstract: A concise summary of the research.
    2. Introduction: Background information and research objectives.
    3. Methodology: Detailed description of research methods.
    4. Results: Presentation of findings, often including statistical analyses.
    5. Discussion: Interpretation of results and their implications.
    6. Conclusion: Summary of key findings and future research directions.

    When writing a research article:

    • Adhere to the specific guidelines of the target journal.
    • Use clear, precise language and avoid jargon where possible.
    • Support your claims with evidence and proper citations.
    • Use tables and figures to present complex data effectively.

    Dissertations

    A dissertation is an extensive research document typically required for doctoral degrees. It presents original research and demonstrates the author’s expertise in their field. Dissertations are comprehensive and follow a structured format:

    1. Abstract
    2. Introduction
    3. Literature Review
    4. Methodology
    5. Results
    6. Discussion
    7. Conclusion
    8. References
    9. Appendices

    Key considerations for writing a dissertation:

    • Develop a clear research question or hypothesis.
    • Conduct a thorough literature review to contextualize your research.
    • Provide a detailed account of your methodology to ensure replicability.
    • Present your results comprehensively, using appropriate statistical analyses.
    • Discuss the implications of your findings in the context of existing literature.
    • Acknowledge limitations and suggest directions for future research.

    Business Reports

    Business reports present research findings in a format tailored to organizational decision-makers. They focus on practical implications and actionable insights. A typical business report structure includes:

    1. Executive Summary
    2. Introduction
    3. Methodology
    4. Findings
    5. Conclusions and Recommendations
    6. Appendices

    When preparing a business report:

    • Begin with a concise executive summary highlighting key findings and recommendations.
    • Use clear, jargon-free language accessible to non-expert readers.
    • Incorporate visuals such as charts, graphs, and infographics to illustrate key points.
    • Focus on the practical implications of your findings for the organization.
    • Provide clear, actionable recommendations based on your research.

  • Describing Variables Nummericaly (Chapter 4)

    Measures of Central Tendency

    Measures of central tendency are statistical values that aim to describe the center or typical value of a dataset. The three most common measures are mean, median, and mode.

    Mean

    The arithmetic mean, often simply called the average, is calculated by summing all values in a dataset and dividing by the number of values. It is the most widely used measure of central tendency.

    For a dataset $$x_1, x_2, …, x_n$$, the mean ($$\bar{x}$$) is given by:

    $$\bar{x} = \frac{\sum_{i=1}^n x_i}{n}$$

    The mean is sensitive to extreme values or outliers, which can significantly affect its value.

    Median

    The median is the middle value when a dataset is ordered from least to greatest. For an odd number of values, it’s the middle number. For an even number of values, it’s the average of the two middle numbers.

    The median is less sensitive to extreme values compared to the mean, making it a better measure of central tendency for skewed distributions[1].

    Mode

    The mode is the value that appears most frequently in a dataset. A dataset can have one mode (unimodal), two modes (bimodal), or more (multimodal). Some datasets may have no mode if all values occur with equal frequency [1].

    Measures of Dispersion

    Measures of dispersion describe the spread or variability of a dataset around its central tendency.

    Range

    The range is the simplest measure of dispersion, calculated as the difference between the largest and smallest values in a dataset [3]. While easy to calculate, it’s sensitive to outliers and doesn’t use all observations in the dataset.

    Variance

    Variance measures the average squared deviation from the mean. For a sample, it’s calculated as:

    $$s^2 = \frac{\sum_{i=1}^n (x_i – \bar{x})^2}{n – 1}$$

    Where $$s^2$$ is the sample variance, $$x_i$$ are individual values, $$\bar{x}$$ is the mean, and $$n$$ is the sample size[2].

    Standard Deviation

    The standard deviation is the square root of the variance. It’s the most commonly used measure of dispersion as it’s in the same units as the original data [3]. For a sample:

    $$s = \sqrt{\frac{\sum_{i=1}^n (x_i – \bar{x})^2}{n – 1}}$$

    In a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, 95% within two standard deviations, and 99.7% within three standard deviations [3].

    Quartiles and Percentiles

    Quartiles divide an ordered dataset into four equal parts. The first quartile (Q1) is the 25th percentile, the second quartile (Q2) is the median or 50th percentile, and the third quartile (Q3) is the 75th percentile [4].

    The interquartile range (IQR), calculated as Q3 – Q1, is a robust measure of dispersion that describes the middle 50% of the data [3].

    Percentiles generalize this concept, dividing the data into 100 equal parts. The pth percentile is the value below which p% of the observations fall [4].

  • Shapes of Distributions (Chapter 5)

    Probability distributions are fundamental concepts in statistics that describe how data is spread out or distributed. Understanding these distributions is crucial for students in fields ranging from social sciences to engineering. This essay will explore several key types of distributions and their characteristics.

    Normal Distribution

    The normal distribution, also known as the Gaussian distribution, is one of the most important probability distributions in statistics[1]. It is characterized by its distinctive bell-shaped curve and is symmetrical about the mean. The normal distribution has several key properties:

    1. The mean, median, and mode are all equal.
    2. Approximately 68% of the data falls within one standard deviation of the mean.
    3. About 95% of the data falls within two standard deviations of the mean.
    4. Roughly 99.7% of the data falls within three standard deviations of the mean.

    The normal distribution is widely used in natural and social sciences due to its ability to model many real-world phenomena.

    Skewness

    Skewness is a measure of the asymmetry of a probability distribution. It indicates whether the data is skewed to the left or right of the mean[6]. There are three types of skewness:

    1. Positive skew: The tail of the distribution extends further to the right.
    2. Negative skew: The tail of the distribution extends further to the left.
    3. Zero skew: The distribution is symmetrical (like the normal distribution).

    Understanding skewness is important for students as it helps in interpreting data and choosing appropriate statistical methods.

    Kurtosis

    Kurtosis measures the “tailedness” of a probability distribution. It describes the shape of a distribution’s tails in relation to its overall shape. There are three main types of kurtosis:

    1. Mesokurtic: Normal level of kurtosis (e.g., normal distribution).
    2. Leptokurtic: Higher, sharper peak with heavier tails.
    3. Platykurtic: Lower, flatter peak with lighter tails.

    Kurtosis is particularly useful for students analyzing financial data or studying risk management[6].

    Bimodal Distribution

    A bimodal distribution is characterized by two distinct peaks or modes. This type of distribution can occur when:

    1. The data comes from two different populations.
    2. There are two distinct subgroups within a single population.

    Bimodal distributions are often encountered in fields such as biology, sociology, and marketing. Students should be aware that the presence of bimodality may indicate the need for further investigation into underlying factors causing the two peaks[8].

    Multimodal Distribution

    Multimodal distributions have more than two peaks or modes. These distributions can arise from:

    1. Data collected from multiple distinct populations.
    2. Complex systems with multiple interacting factors.

    Multimodal distributions are common in fields such as ecology, genetics, and social sciences. Students should recognize that multimodality often suggests the presence of multiple subgroups or processes within the data.

    In conclusion, understanding various probability distributions is essential for students across many disciplines. By grasping concepts such as normal distribution, skewness, kurtosis, and multi-modal distributions, students can better analyze and interpret data in their respective fields of study. As they progress in their academic and professional careers, this knowledge will prove invaluable in making informed decisions based on statistical analysis.

  • Example setup Experimental Design

    Experimental design is a crucial aspect of media studies research, as it allows researchers to test hypotheses about media effects and gain insights into the ways that media affects individuals and society. In this blog post, we will delve into the basics of experimental design in media studies and provide examples of its application.

    Step 1: Define the Research Question The first step in any experimental design is to formulate a research question. In media studies, research questions might involve the effects of media content on attitudes, behaviors, or emotions. For example, “Does exposure to violent media increase aggressive behavior in adolescents?”

    Step 2: Develop a Hypothesis Once the research question has been defined, the next step is to develop a hypothesis. In media studies, hypotheses may predict the relationship between media exposure and a particular outcome. For example, “Adolescents who are exposed to violent media will exhibit higher levels of aggressive behavior compared to those who are not exposed.”

    Step 3: Choose the Experimental Design There are several experimental designs to choose from in media studies, including laboratory experiments, field experiments, and natural experiments. The choice of experimental design depends on the research question and the type of data being collected. For example, a laboratory experiment might be used to test the effects of violent media on aggressive behavior, while a field experiment might be used to study the impact of media literacy programs on critical media consumption.

    Step 4: Determine the Sample Size The sample size is the number of participants or subjects in the study. In media studies, sample size should be large enough to produce statistically significant results, but small enough to be manageable and cost-effective. For example, a study on the effects of violent media might include 100 adolescent participants.

    Step 5: Control for Confounding Variables Confounding variables are factors that may affect the outcome of the experiment and lead to incorrect conclusions. In media studies, confounding variables might include individual differences in personality, preexisting attitudes, or exposure to other sources of violence. It is essential to control for these variables by holding them constant or randomly assigning them to different groups.

    Step 6: Collect and Analyze Data The next step is to collect data and analyze it to test the hypothesis. In media studies, data might include measures of media exposure, attitudes, behaviors, or emotions. The data should be collected in a systematic and reliable manner and analyzed using statistical methods.

    Step 7: Draw Conclusions Based on the results of the experiment, conclusions can be drawn about the research question. The conclusions should be based on the data collected and should be reported in a clear and concise manner. For example, if the results of a study on the effects of violent media support the hypothesis, the conclusion might be that “Exposure to violent media does increase aggressive behavior in adolescents.”

    In conclusion, experimental design is a critical aspect of media studies research and is used to test hypotheses about media effects and gain insights into the ways that media affects individuals and society. By following the seven steps outlined in this blog post, media studies researchers can increase the reliability and validity of their results and contribute to our understanding of the impact of media on society.

  • Experimental Design

    Experiments are a fundamental part of the scientific method, allowing researchers to systematically investigate phenomena and test hypotheses. Setting up an experiment is a crucial step in the process of conducting research, and it requires careful planning and attention to detail. In this essay, we will outline the key steps involved in setting up an experiment.

    Step 1: Identify the research question

    The first step in setting up an experiment is to identify the research question. This involves defining the problem that you want to investigate and the specific questions that you hope to answer. This step is critical because it sets the direction for the entire experiment and ensures that the data collected is relevant and useful.

    Step 2: Develop a hypothesis

    Once you have identified the research question, the next step is to develop a hypothesis. A hypothesis is a tentative explanation for the phenomenon you want to investigate. It should be testable, measurable, and based on existing evidence or theories. The hypothesis guides the selection of variables, the design of the experiment, and the interpretation of the results.

    Step 3: Define the variables

    Variables are the factors that can influence the outcome of the experiment. They can be classified as independent, dependent, or control variables. Independent variables are the factors that are manipulated by the experimenter, while dependent variables are the factors that are measured or observed. Control variables are the factors that are kept constant to ensure that they do not influence the outcome of the experiment.

    Step 4: Design the experiment

    The next step is to design the experiment. This involves selecting the appropriate experimental design, deciding on the sample size, and determining the procedures for collecting and analyzing data. The experimental design should be based on the research question and the hypothesis, and it should allow for the manipulation of the independent variable and the measurement of the dependent variable.

    Step 5: Conduct a pilot study

    Before conducting the main experiment, it is a good idea to conduct a pilot study. A pilot study is a small-scale version of the experiment that is used to test the procedures and ensure that the data collection and analysis methods are sound. The results of the pilot study can be used to refine the experimental design and make any necessary adjustments.

    Step 6: Collect and analyze data

    Once the experiment is set up, data collection can begin. It is essential to follow the procedures defined in the experimental design and collect data in a systematic and consistent manner. Once the data is collected, it must be analyzed to test the hypothesis and answer the research question.

    Step 7: Draw conclusions and report results

    The final step in setting up an experiment is to draw conclusions and report the results. The data should be analyzed to determine whether the hypothesis was supported or rejected, and the results should be reported in a clear and concise manner. The conclusions should be based on the evidence collected and should be supported by statistical analysis and a discussion of the limitations and implications of the study.

  • Example Before and After Study

    Research question: Does watching a 10-minute news clip on current events increase media literacy among undergraduate students?

    Sample: Undergraduate students who are enrolled in media studies courses at a university

    Before measurement: Administer a pre-test to assess students’ media literacy before watching the news clip. This could include questions about the credibility of sources, understanding of media bias, and ability to identify different types of media (e.g. news, opinion, entertainment).

    Intervention: Ask students to watch a 10-minute news clip on current events, such as a segment from a national news program or a clip from a news website.

    After measurement: Administer a post-test immediately after the news clip to assess any changes in media literacy. The same questions as the pre-test can be used to see if there were any significant differences in student understanding after watching the clip.

    Analysis: Use statistical analysis, such as a paired t-test, to compare the pre- and post-test scores and determine if there was a statistically significant increase in media literacy after watching the news clip.For example, if the study finds that the average media literacy score increased significantly after watching the news clip, this would suggest that incorporating media clips into media studies courses could be an effective way to increase students’ understanding of media literacy
