The Teaching for Transformative Experiences in Science (TTES) model was designed to facilitate the application of academic learning in students' everyday experiences. In the current study, we describe a 2-year design-based intervention that aimed to further develop and evaluate the TTES model. In the first year, a teacher implemented the TTES model in two of his four classes. The findings indicated enhanced engagement and learning, but primarily among students with higher prior engagement and learning. Insights led to revision of the TTES model. In the second year, the revised TTES model was implemented in all the teacher's classes, with another teacher's classes used for comparison. Intervention students demonstrated significantly greater learning and reported significantly higher levels of transformative experience than the comparison students.

Women are underrepresented in many undergraduate geoscience programs. Some departments are more successful at recruiting and retaining female students than others. To understand why, we investigated potential differences between more and less successful geoscience departments in terms of social support, institutional supports, institutional barriers, perceived connection to instructors, and transformative experiences. We collected data from 2,041 undergraduate geoscience students enrolled in six geoscience departments at public, four-year institutions across the United States. We recruited two departments that were successful at graduating a high percentage of female students compared to the national average (high-success sites), two departments with a moderate percentage (medium-success sites), and two with a low percentage (low-success sites). Students at high-success sites reported greater institutional supports, greater perceived connection to instructors, and lower institutional barriers than did students at medium- and low-success sites. Nonmajors at high-success sites reported higher levels of transformative experience than nonmajors at low-success sites. No significant differences were found between medium- and low-success sites. Across all sites, female students perceived less of a connection to their instructors and endorsed a lower level of transformative experience than did male students. We did not find gender differences in terms of the other factors. We also did not find gender by site interactions, suggesting that the success of high-success sites in recruiting and retaining women was associated with supporting all students. These results suggest departments can increase effectiveness in recruiting and retaining female student by increasing institutional supports, reducing institutional barriers, connecting with students, and fostering transformative experiences.

Conflicting research results have stirred controversy over the effectiveness of problem-based learning (PBL) compared to direct instruction at fostering content learning, particularly for novices. We addressed this by investigating effectiveness with respect to recognition learning and transfer and conducting an aptitude-treatment interaction analysis. We also examined how students' goal orientations may moderate learning in PBL and lecture/discussion environments. Participants included 197 preservice teachers in an undergraduate educational psychology course. Controlling for GPA, students in the PBL condition performed significantly better than students in the lecture/discussion condition on a transfer measure (p <.001, partial η² =.271) and equally on a recognition learning measure (p =.530). We also found an aptitude-treatment interaction for recognition learning (p =.012, partial η² =.034) but not transfer (p =.088). Results of goal orientation on learning outcomes were inconclusive.

Transformative experience represents a deep-engagement construct and refers to experiences in which students use science content to see and experience the world in meaningful new ways outside the classroom. Such experiences are associated with deep learning (e.g., transfer) and engagement (e.g., academic and career choice) outcomes. However, research on individual factors predictive of transformative experience is limited. The current study investigated university geoscience students’ perceptions of a connection to their instructor(s) and perceptions of their instructors’ passion for the content as predictors of transformative experience. Controlling for students’ initial interest and self-efficacy in the domain, we found both these factors to be predictive of transformative experience. These results suggest science teachers may be able to support engagement in transformative experiences by connecting with students and expressing a passion for the content.
