Process | Description | Operationalization in our sample study |
---|---|---|
1. Choose participants1,4 and collect data1,3,4 | Select participants who are experts in the area of interest for the study. Collect data in the form of interviews, focus groups, and/or artifacts. | We interviewed instructors with experience teaching SCALE-UP physics. |
2. Purposively sample data4 | Depending on the amount of data collected, sample data to include data from a broad group of participants. | We sampled data based on the instructors’ institutional factors and SCALE-UP and overall teaching experience. |
3. Identify causal statements1,2,3,4 | Identify causal statements by searching for key linking words. Searching for: if, then, because/‘cause, so, since think/thought, know/knew, use, believe, feel/felt. | Same |
4. Separate causes and effects1,2,3,4 | Separate causal statement into causes and effects by looking at directionality of linking words. | Same |
5. Inter-rater reliability on identification of causal statements1,4 | Investigate reliability of coding for causal statements. | First two authors independently coded each interview for causal statements and these responses were compared. |
6. Identify relevant concepts1,3,4 | Group frequently mentioned words from both causes and effects into categories (names are based on the participants’ own words). | Same |
7. Inter-rater agreement on concept identification1 | Investigate reliability of concepts identified in causal statements. | Same |
8. Construct raw causal map for each participant1,2,3,4 | Use concepts and causal statements to construct causal map for each participant. | This was the end of our sample analysis as we only investigated four instructors. Future studies should continue the process. |
9. Aggregate raw causal maps based on relevant sampling variables1,2,3,4 | Combine causal maps for related participants to create an aggregate causal map. Participants can be grouped by variables of interest. | In future studies, we will group instructors by their institution and prior SCALE-UP and overall teaching experience. |
10. Member checking2 | Discuss causal map and aggregate causal maps with participants to check for appropriateness of interpretations and correctness of findings (Lincoln & Guba, 1985). | In future studies, we will follow-up with instructors to check our interpretation of their interviews and causal statements. |
11. Analyze aggregated causal maps1,2,3,4 | Use metrics such as the point of redundancy1,2,3,4, adjacency matrix2,3,4, reachability matrix1,2,3,4, centrality1,3, and density1,4 to analyze and validate the aggregated causal maps. | In future studies, we will investigate the aggregated causal maps. |
