Active Learning Helps Students Develop Research Skills!
Unlike journal articles, research cases describe decision-making, and in-the-moment course corrections when the pristine research design encounters the muddy real world. They provide an excellent basis for active learning for individual students or team projects. The ten-step process outlined below offers students the opportunity to dig deeply into the case, then to research and evaluate alternative options.
This SRM case is available open access through June 2024:
LaPlume, A., (2022). Challenges and solutions for data analysis in an adult lifespan study of over 100,000 online cognitive test completions. In Sage Research Methods: Doing Research Online. SAGE Publications, Ltd.
Abstract: In this case study, I describe methodological insights from data analysis of an online adult lifespan dataset (over 100,000 completions, ages 15–100). The data were used to study cross-sectional age differences in cognitive performance. I cover the steps of data analysis for large-scale web-based data, namely data cleaning, analysis, and visualization techniques. In each step, I describe the unique challenges that face analysis of data collected online, and potential solutions to address them, by drawing on practical lessons and examples from this study.
A Ten-Step Process for Teaching and Learning with Research Cases
LaPlume brings big data analysis to life, giving us an inside look at the practices used and lessons learned. We can benefit from these lessons, whether or not we are interested in the topic of this particular study. Use all ten steps for a series of activities, select the ones that fit your course or seminar, or adapt to use for your own skills development.
1. Understand the research approach.
The case study focuses on the analytic stage of research. The author used quantitative data analysis of an online dataset with statistical modelling. The case study walks through steps for data cleaning and visualization. To understand the case, you will need to be familiar with key terms and concepts. Look for research handbooks or dictionaries, or the glossaries in research texts to learn more about terms new to you.
Can you briefly define these terms?
Statistical modelling
Data cleaning
Data visualization
Non-Linear Regression
Model comparison and selection
Data resampling
Covariates
Cross-sectional differences
2. State the methodological problem(s).
Study the challenges the author described about using and analyzing large-scale online data.
What specific methodological problems are stated in the case? How did she differentiate between strategies for small or large datasets? Can you identify additional challenges the author did not mention?
Sage Research Methods (SRM) includes an extensive, multi-disciplinary collection of cases that illustrate how quantitative, qualitative, and mixed methods social science studies are conducted. Learn more about teaching with cases here.

3. Explain how the case author addresses the problem(s).
Summarize the strategies used to address the methodological challenges associated with analyzing large collections of data.
4. Identify unanswered questions.
Building on your understanding of the case, what strategies for large-scale data analysis are missing? What methodological questions are unanswered? What information is incomplete or inadequate?
5. Broaden the inquiry; research the problem and unanswered questions.
Select one or more of the unanswered questions you identified to pursue further. Find credible sources or examples to fill in the knowledge or information gaps in this case.
6. Offer alternative solutions and methodological approaches to the problem.
Find at least one case or article that covers analysis of large datasets. Based on your research, what are other options this author could take to analyze and/or visualize this large set of online data? Provide examples from other studies as relevant. Cite your sources.
7. Evaluate each alternative.
Weigh the advantages and disadvantages of the potential approaches you suggested in response to question 6.
8. Offer your best recommendation.
State your recommendation for the best alternative given the circumstances, obstacles, and factors described in the case.
9. Describe implementation.
How would you carry out the analytic process you suggested in response to question 8? What tools, team members, or other resources will you need to implement this approach?
10. Finalize the case analysis.
Complete the paper, presentation, or team project as assigned.
