Collaborative, project-based learning models have been shown to benefit student learning and engagement in the STEM disciplines. This case study evaluates the use of highly collaborative project- and problem-based learning models in introductory courses in the geosciences and biology. In the geosciences, we developed project-based modules with a strong local focus. Student teams worked on three project-based laboratories dealing with the local geology/geomorphology, water quality of a local stream, and local flooding issues. These replaced traditionally taught laboratories on topographic maps and rivers and streams. Student teams presented project results in lieu of taking a traditional laboratory practical. In biology, we designed a collaborative learning model that incorporated three problem-based learning modules into a first-semester introductory biology course. Students were assigned topics in evolution, cell biology and genetics to research independently during the course of the semester, with each module culminating in a brief presentation on the topic. Modules were designed to mirror concepts being covered in the lecture. Preliminary results suggest that student performance and attitudes towards course material benefitted from this learning model. The authors consider outcomes, benefits, and challenges to students and instructors.
The relative effectiveness of strictness theory and modernization theory in explaining congregational growth is tested using a random sample of white, Protestant churches in Middletown (N = 98). Although the former theory predicts that growth is positively related to an authoritative structure and to enforcing rules of ascetic strictness, modernization theory predicts the opposite pattern. For our sample, authoritative leadership seemed not to produce congregational growth. The main finding was that strict rules positively related to growth among working-class congregations, but negatively related to growth among middle-class congregations.
This research is based on an ethnographic study of a protestant evangelical congregation. This work demonstartes how the evangelical tradition of translating religious beliefs and practices into contemporary vernacular is accomplished through the tools and contents of mass media. Interpretations of the data focus primarily on gender and emotion. Looking at this particular group helps us to understand how many groups negoatiate boundaries on an ever-shifting cultural field in pluralistic societies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
