Introductory Biology Courses: A Framework To Support Active Learning in Large Enrollment Introductory Science Courses

Active learning and research-oriented activities have been increasingly used in smaller, specialized science courses. Application of this type of scientific teaching to large enrollment introductory courses has been, however, a major challenge. The general microbiology lecture/laboratory course described has been designed to incorporate published active-learning methods. Three major case studies are used as platforms for active learning. Themes from case studies are integrated into lectures and laboratory experiments, and in class and online discussions and assignments. Students are stimulated to apply facts to problem-solving and to learn research skills such as data analysis, writing, and working in teams. This course is feasible only because of its organizational framework that makes use of teaching teams (made up of faculty, graduate assistants, and undergraduate assistants) and Web-based technology. Technology is a mode of communication, but also a system of course management. The relevance of this model to other biology courses led to assessment and evaluation, including an analysis of student responses to the new course, class performance, a university course evaluation, and retention of course learning. The results are indicative of an increase in student engagement in research-oriented activities and an appreciation of real-world context by students.     

Nap schedules and sleep practices in infant-toddler groups

This article describes and analyzes sleep-wake schedules and nap times in multiage infant-toddler groups through three case studies based on ethnographic research conducted in two Finnish day care centers. The study asks how day care centers and homes in collaboration can protect children’s biological sleep-wake rhythms and the physiological effectiveness of sleep. Data were derived through participant-observation in the groups, taped interviews with staff and parents, and sleep diaries kept by the parents. Findings show some of the complex interactions among family daily patterns, day care patterns, and sleep disturbances in very young children. The findings further show that major differences exist in day care practices regarding the quality of sleep and its physiological effectiveness. These differences are related to three issues: (1) whether the timing of naps in the multiage group is simultaneous or staggered in an age-appropriate and individually appropriate manner; (2) how efficiently the home/day care personnel communicate with one another; and (3) what is the awareness level of the day care staff about the significance of the sleep environment. The article further discusses the team aspect of protective practices, differences between caregivers and their differences in organizing work, as well as implications for further research and for caregiver training.     

Are there implications for prevention research from studies of resilience?

In this commentary, the question is raised whether prevention research can benefit from resilience research in designing interventions. Although many areas in the investigative interests of prevention and resilience researchers overlap, Luthar, Cicchetti, and Becker may have set the bar too high for defining resilience in the context of varying levels of adversity.     

Action learning: developing critical competencies for knowledge era workers

For most of the twentieth century, the goal in education was the generation and dissemination of information. With the rise of technology and unlimited access to information, it is the ability to apply knowledge and learn from experience that is the new priority for employee development. Action learning, with its emphasis on action and reflection, provides an effective means to develop the learning competencies our new world requires. This article describes the action learning process used in a Fortune 500 company and highlights the findings of a learning competencies evaluation survey.
