TABLE 2.
Summary statistics based on PITS and LCAS survey scores for students who had taken a synthetic biology CURE laboratory
| Survey | Mean | SD | Cronbach's α |
|---|---|---|---|
| PITS (all out of 5) | |||
| Project ownership‐content | 3.62 | 1.18 | 0.90 |
| Project ownership‐emotion | 3.35 | 0.99 | 0.89 |
| Self‐efficacy | 4.40 | 0.68 | 0.83 |
| Self‐identity | 4.07 | 0.99 | 0.87 |
| Scientific community values | 4.35 | 0.86 | 0.83 |
| Networking | 3.62 | 1.29 | 0.81 |
| LCAS | |||
| Collaboration (out of 4) | 3.50 | 0.88 | 0.68 |
| Discovery and relevance (out of 5) | 4.26 | 0.78 | 0.85 |
| Iteration (out of 5) | 4.15 | 0.85 | 0.78 |
Note: The mean and SD of the students' answers were determined by converting the Likert scale to a numerical scale where Strongly Agree = 5, Agree = 4, Neither agree nor disagree = 3, Disagree = 2, and Strongly Disagree = 1 for all survey questions, except for LCAS‐Collaboration. LCAS‐Collaboration questions had a four‐point scale with 1 = never; 2 = once or twice; 3 = monthly; 4 = weekly. Cronbach's (1951) alpha was measured using the package “ltm” 20 in R 21 to ensure the reliability or internal consistency of the PITS and LCAS test items. All scores were out of 5, except for LCAS‐Collaboration (out of 4).
