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.     

Contemporary perspectives of the child in action: an investigation into children’s connectedness with,and contribution to,the world around them

Childcare within Australia has undergone significant reform as a result of the implementation of the nationally mandated Belonging, Being and Becoming: The Early Years Learning Framework [EYLF] (Department for Education, Employment and Workplace Relations [DEEWR]. 2009. Belonging, Being and Becoming. The Early Years Learning Framework for Australia. Canberra: Australian Government Department of Education, Employment and Workplace Relations). The EYLF articulates contemporary perspectives of the child through its principles, practices and learning outcomes. Educators are required to promote these principles, practices and learning outcomes with children aged from birth to 5 years. This paper reports the findings from a research project that sought to investigate how educators applied their understanding of learning outcome two of the EYLF (children are connected with and contribute to their world). The focus of this research was educators working with children aged two to three years within childcare centres operating on school sites, in metropolitan Western Australian. The research design was qualitative and situated within the interpretivist paradigm. Observations were used as the method for gathering data and these were analysed through a process of coding. This paper presents the observational findings of educators’ practices within learning outcome two. Composite vignettes from the voice of the child are included to present the observational findings. In centralising the voice of the child, contemporary perspectives are made explicit.     

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.     

Teaching algorithmic problem solving or conceptual understanding: Role of developmental level,mental capacity,and cognitive style

It has been shown previously that many students solve chemistry problems using only algorithmic strategies and do not understand the chemical concepts on which the problems are based. It is plausible to suggest that if the information is presented in differing formats, the cognitive demand of a problem changes. The main objective of this study is to investigate the degree to which cognitive variables, such as developmental level, mental capacity, and disembedding ability explain student performance on problems which: (1) could be addressed by algorithms or (2) require conceptual understanding. All conceptual problems used in this study were based on a figurative format. The results obtained show that in all four problems requiring algorithmic strategies, developmental level of the students is the best predictor of success. This could be attributed to the fact that these are basically computational problems, requiring mathematical transformations. Although all three problems requiring conceptual understanding had an important aspect in common (the figurative format), in all three the best predictor of success is a different cognitive variable. It was concluded that: (1) the ability to solve computational problems (based on algorithms) is not the major factor in predicting success in solving problems that require conceptual understanding; (2) solving problems based on algorithmic strategies requires formal operational reasoning to a certain degree; and (3) student difficulty in solving problems that require conceptual understanding could be attributed to different cognitive variables.     

Diluting education? An ethnographic study of change in an Australian Ministry of Education

This ethnographic study captures the processes that led to change in an Australian public education system. The changes were driven by strong neo-liberal discourses which resulted in a shift from a shared understanding about leading educational change in schools by knowledge transfer to managing educational change as a process, in other words, allowing the schools to decide how to change. Inside an Australian state education bureaucracy at a time when the organisation was restructured and services decentralised, this study helps show some of the disturbing trends resulting from the further entrenchment of neo-liberal strategies. Although control was re-centralised by legitimising performance mechanisms, in the form of national testing, there are indications that the focus on national tests may have alarming consequences for the content and context of education. I argue that the complexities of learning and fundamental pedagogies are being lost in preference for an over-reliance on data systems that are based on a shallow and narrow set of standardised measures.     

Cohorts and Relatedness: Self-Determination Theory as an Explanation of How Learning Communities Affect Educational Outcomes

This study examines whether feelings of relatedness constitute a substantial means by which learning communities (cohorts) improve learning outcomes in higher education. It applies Ryan and Deci’s Self-Determination Theory to an analysis of the National Survey of Student Engagement. The SDT hypothesizes that environments that support perceptions of social relatedness improve motivation, thereby positively influencing learning behavior. The authors propose that participation in cohort programs constitutes such an environment. Measuring student perceptions of the contributions of their institutions, the study found increased relatedness to peers and faculty and increased higher order thinking assignments (a control variable included in the research model) to be substantial predictors of educational outcomes relevant to literacy, critical thinking, and, especially, job preparation. The researchers suggest that institutions will want to ensure that their learning community designs enhance student feelings of relatedness.     

“I am in School!”: African American Male Youth in a Prison/College Hybrid Figured World

Educational programs are seen as a vehicle for improving the educational experiences and life outcomes for youthful offenders. In 1998 North Carolina started the Workplace and Community Transition Youth Offender Program (YOP). The program offers youth post-secondary educational courses. Our study examines 2007–2009 data from YOP youth participating in the program. Using students’ voices our study shows that YOP not only decreases recidivism drastically, but has a personal impact in the youth participants’ lives. YOP provides a space of change that is not prison or a traditional college. The hybrid figured world provides an opportunity for African American male youth to re/author themselves creating new hybrid identities. The youth author themselves as students versus inmates. These new identities and educational competencies have potentially long term benefits for youth offenders and for communities.
