Example 1: Impact of Social Media on Teenagers' Mental Health
* Type: Empirical Studies (quantitative and qualitative)
* Examples:
* Quantitative: A study published in the *Journal of Adolescent Health* that analyzed survey data on social media usage and depression levels in a sample of teenagers. This would be used to support claims about correlations or causal relationships.
* Qualitative: A study published in *Qualitative Health Research* that conducted interviews with teenagers about their experiences with social media and its impact on their self-esteem. This provides in-depth understanding of the lived experience.
* Meta-analysis: A review article synthesizing findings from multiple studies on the relationship between social media use and anxiety in adolescents. This provides a broad overview of the existing research.
* Relevance: These studies provide evidence and theoretical frameworks for understanding the potential negative effects of social media on teenagers' mental health. They support the research question and methodology.
Example 2: Effectiveness of a New Teaching Method in Elementary Schools
* Type: Theoretical Frameworks, Empirical Studies, Review Articles
* Examples:
* Theoretical Framework: A chapter from a textbook on educational psychology outlining different learning theories, such as constructivism or behaviorism, relevant to the new teaching method. This provides a foundation for understanding the method's basis.
* Empirical Studies: Research papers published in educational journals that have evaluated the effectiveness of similar teaching methods in similar age groups. This helps to contextualize the effectiveness of the new method.
* Review Articles: A systematic review summarizing the existing literature on the effectiveness of different teaching methods for elementary school students. This offers a comprehensive overview of the field.
* Relevance: These sources provide a theoretical basis for the new teaching method, demonstrate the feasibility of evaluating similar methods, and provide benchmarks for comparison.
Example 3: The Economic Impact of Climate Change on Coastal Communities
* Type: Government Reports, Economic Models, Case Studies
* Examples:
* Government Reports: Reports from the IPCC (Intergovernmental Panel on Climate Change) detailing the projected impacts of climate change on sea levels and coastal erosion. This offers crucial background data and projections.
* Economic Models: Studies using econometric models to predict the economic losses associated with coastal flooding and damage to infrastructure. This provides quantitative evidence of the economic impact.
* Case Studies: Analyses of specific coastal communities that have already experienced significant economic losses due to climate-related events. This provides real-world examples and illustrates the potential impacts.
* Relevance: These sources provide data, projections, and real-world examples to support claims about the severity and scope of the economic impact of climate change on coastal communities.
In each example, the related literature is not just a list of sources; it's a carefully selected and analyzed set of works that provides a foundation for the research, supports the research questions, and contributes to the overall argument. The *relevance* of each source to the research is crucial and needs to be explicitly stated within the research paper.
