Foraging ecology of the Philippine flying lemur (Cynocephalus volans)

Between August 1986 and September 1987, six Philippine flying lemurs (Cynocephalus volans) were observed foraging on 35 of 76 available species of trees, representing ≥12 families of ≥26 available families. Eight species were foraged on in amounts significantly greater than expected, given the tree\u27s abundance on the study area, and four were foraged on significantly less than expected. The foraging strategy of C. volans involved foraging many times during the night, for short duration, in several different species of tree each night. This strategy differed from that of other arboreal folivores

A Framework for Implementing Course-Based Undergraduate Research Experiences (CUREs) in Freshman Biology Labs

© 2016 National Association of Biology Teachers. All rights reserved. There have been many calls to make research experiences available to more undergraduate students. One way to do this is to provide course-based undergraduate research experiences (CUREs), but providing these on a scale large enough to accommodate many students can be a daunting undertaking. Indeed, other researchers have identified time to develop materials and course size as significant barriers to widespread implementation of CUREs. Based on our own experiences implementing CUREs at a large research university, we present a flexible framework that we have adapted to multiple research projects, share class materials and rubrics we have developed, and suggest logistical strategies to lower these implementation barriers

Perceptions of Active Learning between Faculty and Undergraduates: Differing Views among Departments

There have been numerous calls recently to increase the use of active learning in university science, technology, engineering, and math (STEM) classrooms to more actively engage students and enhance student learning. However, few studies have investigated faculty and student perceptions regarding the effectiveness of active learning or the barriers to its implementation. Previous work surveying a single class in a single department has suggested that faculty and students have different perceptions of the effectiveness of active learning strategies and the barriers faculty face when implementing these teaching strategies. We expand on these previous findings by surveying a larger and more diverse sample of students and faculty in a college consisting of five departments. We find that students and faculty agree that active learning techniques are useful, effective, and should be implemented more widely, but disagree on the percentage of class time currently devoted to active learning. When we parsed the data by department, more nuanced perceptions became apparent. The perceived barriers to implementing teaching reform differed in importance by department and in some departments relatively few faculty had observed or used active learning. Our findings suggest that advocates of teaching reform must recognize that not all departments or institutions face the same barriers to implementing curricular changes

Roles matter: Graduate student perceptions of active learning in the STEM courses they take and those they teach

Despite many calls to reform undergraduate science, technology, engineering, and math (STEM) education to incorporate active learning into classes, there has been little attention paid to graduate level classrooms or courses taught by graduate students. Here, we set out to understand if and how STEM graduate students’ perceptions of active learning change in the classes they take versus those they teach. We found that graduate students had taken relatively few graduate level classes using active learning and they felt that more time should be devoted to active learning in the courses they were taking. Teaching assistants felt that they were devoting the right amount of class time to active learning in the classes they taught. Graduate students also felt that they were using teaching methods in the classes they taught that were different from those they thought should be used when teaching undergraduates and were different from how they preferred to learn when taking classes

Scientific teaching targeting faculty from diverse institutions

We offered four annual professional development workshops called STAR (for Scientific Teaching, Assessment, and Resources) modeled after the National Academies Summer Institute (SI) on Undergraduate Education in Biology. In contrast to the SI focus on training faculty from research universities, STAR\u27s target was faculty from community colleges, 2-yr campuses, and public and private research universities. Because of the importance of community colleges and 2-yr institutions as entries to higher education, we wanted to determine whether the SI model can be successfully extended to this broader range of institutions. We surveyed the four cohorts; 47 STAR alumni responded to the online survey. The responses were separated into two groups based on the Carnegie undergraduate instructional program categories, faculty from seven associate\u27s and associate\u27s-dominant institutions (23) and faculty from nine institutions with primarily 4-yr degree programs (24). Both groups expressed the opinion that STAR had a positive impact on teaching, student learning, and engagement. The two groups reported using techniques of formative assessment and active learning with similar frequency. The mix of faculty from diverse institutions was viewed as enhancing the workshop experience. The present analysis indicates that the SI model for training faculty in scientific teaching can successfully be extended to a broad range of higher education institutions. © 2013 C. S. Gregg et al

A conceptual framework for graduate teaching assistant professional development evaluation and research

© 2016 T. D. Reeves et al. Biology graduate teaching assistants (GTAs) are significant contributors to the educational mission of universities, particularly in introductory courses, yet there is a lack of empirical data on how to best prepare them for their teaching roles. This essay proposes a conceptual framework for biology GTA teaching professional development (TPD) program evaluation and research with three overarching variable categories for consideration: outcome variables, contextual variables, and moderating variables. The framework’s outcome variables go beyond GTA satisfaction and instead position GTA cognition, GTA teaching practice, and undergraduate learning outcomes as the foci of GTA TPD evaluation and research. For each GTA TPD outcome variable, key evaluation questions and example assessment instruments are introduced to demonstrate how the framework can be used to guide GTA TPD evaluation and research plans. A common conceptual framework is also essential to coordinating the collection and synthesis of empirical data on GTA TPD nationally. Thus, the proposed conceptual framework serves as both a guide for conducting GTA TPD evaluation at single institutions and as a means to coordinate research across institutions at a national level

Biology Intensive Orientation for Students (BIOS): A Biology “Boot Camp”

The Biology Intensive Orientation for Students (BIOS) Program was designed to assess the impact of a 5-d intensive prefreshman program on success and retention of biological science majors at Louisiana State University. The 2005 pilot program combined content lectures and examinations for BIOL 1201, Introductory Biology for Science Majors, as well as learning styles assessments and informational sessions to provide the students with a preview of the requirements of biology and the pace of college. Students were tracked after their BIOS participation, and their progress was compared with a control group composed of students on the BIOS waiting list and a group of BIOL 1201 students who were identified as the academic matches to the BIOS participants (high school GPA, ACT score, and gender). The BIOS participants performed significantly better on the first and second exams, they had a higher course average, and they had a higher final grade than the control group. These students also had higher success rates (grade of “A,” “B,” or “C”) during both the fall and spring semesters and remained on track through the first semester of their sophomore year to graduate in 4 yr at a significantly higher rate than the control group

The CURE for Cultivating Fastidious Microbes

Course-based Undergraduate Research Experiences (CUREs) expand the scientific educational benefits of research to large groups of students in a course setting. As part of an ongoing effort to integrate CUREs into first-year biology labs, we developed a microbiology CURE (mCURE) that uses a modified dilution-to-extinction high throughput culturing protocol for isolating abundant yet fastidious aquatic bacterioplankton during one semester. Students learn common molecular biology techniques, including molecular characterization; read and evaluate scientific literature; and receive training in scientific communication through written and oral exercises that incorporate social media elements. In the first three semesters, the mCUREs achieved similar cultivability success as implementation of the protocol in a standard laboratory setting. Our modular framework facilitates customization of the curriculum for use in multiple settings and we provide classroom exercises, assignments, assessment tools, and examples of student output to assist with implementation
