This action research study, set in a community college in the southwestern United States, was designed to investigate the effects of implementing cooperative learning strategies in a developmental mathematics course. Introductory algebra was formerly taught in a lecture based format, and as such regularly had a low course completion rate. To create a more engaging learning environment, formal and informal cooperative learning activities were integrated into the curriculum. Bandura's self-efficacy theory, Vygotsky's constructivist theory, and Deutsch's social interdependence theory guided this study. Qualitative and quantitative data were collected through pre and post self-efficacy surveys, semi-structured student interviews, student journal entries, class observations, focus groups, and pre and post mathematics assessments. Data were analyzed using a mixed methods approach. As a result of implementing cooperative learning practices as a part of my teaching, there was an increase in student attendance as well as a decrease in student withdrawal rates. Students were also more motivated to work with each other on mathematics homework outside of class sessions. There was a strong sense of community that I had not witnessed in previous courses that I have taught. Use of cooperative learning practices served as a vehicle to motivate students to work on their mathematics coursework with their peers.

Health science students like students in many disciplines exhibit difficulty with transferring content from one course to another. For example, the problem explored in this study occurred when overlapping concepts were presented in introductory biology and chemistry courses, but students could not transfer the concepts to the other disciplinary course. In this mixed method action research study, the author served as facilitator/leader of a group of colleagues tasked with investigating and taking steps to resolve this student learning transfer problem. This study outlines the details of how an interdisciplinary community of practice (CoP) formed between chemistry and biology faculty members at a community college to address the problem and the benefits resulting from the CoP. Quantitative and qualitative data were obtained from transcripts of meetings of the faculty members, notes from other formal and informal meetings, classroom visits, a questionnaire containing Likert and open-ended items and interviews. Transcripts, notes, and interviews were coded to determine common themes. Findings suggested the CoP was an effective means to deal with the matter of student transfer of content across courses. In particular, the CoP agreed to use similar terminology, created materials to be used consistently across the courses, and explored other transfer specific approaches that allowed for transfer of course content. Finally, the benefits of the CoP were due in large part to the collaboration that took place among participants.
