Developing a Research Agenda in Science Education

The Science Summit reinforced a question upon which many of us in science education are focused: How can we, the science education community of researchers, practitioners, and consumers, lead policy? We include a brief review of the No Child Left Behind Act and its implications for teachers, and elaborate about one ongoing and growing effort to answer the concerns about the paucity of research expressed at the Summit. We describe a unique and growing collaboration across professional science education and science organizations and societies that focuses on the development of a research agenda. The term ‘consilience’ refers to the “jumping together of knowledge” that leads to scientific advancements, progressive, creative, fluid scientific research and intellectual capacity to move a research community toward an enlightened research agenda. A coherent research agenda enables us to specify what we know, what we need to know, and how research can be employed for creating and implementing policy. The use of a dynamic organizer (such as Pasteur’s Quadrant) for a research matrix of topics provides a possible structure for organizing and cataloging research questions, designs, findings from past studies, needed areas for research, and policy implications. Through this unique collaboration, the science education community can better focus on needs and priorities and ensure that teachers, policy makers, scientists, and researchers in education at local through national levels have an important stake in research priorities and actions.     

The pedagogical benefits of enacting positive psychology practices through a student–faculty partnership approach to academic development

Academic development that supports the enactment of positive psychology practices through student–faculty pedagogical partnership can increase faculty confidence and capacity in their first year in a new institution. When student partners practice affirmation and encouragement of strengths-based growth, processes of faculty acclimation and self-authoring can be accelerated. This article presents a student–faculty pedagogical partnership program and positive psychology practices that focus on faculty strengths and capacities as the foundation for reinforcing and revising existing pedagogical strategies and for sustaining energy for continued development. It combines collaborative autoethnographic and comparative case study approaches to investigate the pedagogical benefits of these practices.     

Expectancies as mediators in the differential-reward conditional discrimination performance of pigeons

In a series of within-subject experiments employing a two-choice delayed conditional discrimination task, pigeons chose correctly more often when kind of correct choice and kind of reinforcer were perfectly correlated than when uncorrelated. Correct choice behavior fell to chance levels when the correlation was reversed or when it was removed by using only one kind of reinforcer. Implications for mediation theories are discussed, with the conclusion being that, although the possibility that instrumental mediators are present in this situation cannot be dismissed, the overall pattern of results indicates that classical mediators are of principal importance in this type of task.     

Community college student-parents: priorities for persistence

This study of community college student-parents used interpretive phenomenological analysis of interview data contributed by 15 participants from three Mountain West Community Colleges. The participants qualified by the following criteria: had delayed college entrance by 2 years or more, had a child not yet in kindergarten, were full-time students in an associate degree program, worked part-time, and had 15 credits or more toward their degree. This study revealed what it meant for student-parents to have success while they addressed the challenges of balancing work, home, child care, and academic responsibilities. The student-parents described experiences that required prioritizing responsibilities, managing time effectively, securing needed support services, addressing stress, developing strategies for study and parenting, and maintaining a positive mindset. The findings include quotations that describe the challenges of each student-parent; whether individually unique, conflicting, or shared by the subset of this nontraditional student group. The student-parents shared a common sense of resolve to use prioritizing strategies as they made decisions affecting their degree completion. Student-parents had the common goal to obtain a better life for themselves and their children.     

Learner preferences and prior knowledge in learner-controlled computer-based instruction

This study examined the effects of prior knowledge, learner preference for control, and type of control (learner or program) on the achievement of middle-school students in a computer-based instructional program on adding and subtracting integers. Students were blocked by preference-for-control scores and randomly assigned to either a learner-control or program-control version of instruction. A significant three-way interaction (prior knowledge × preference scores × type of control) revealed that students with high prior knowledge achieved better on the posttest when their preference for control was matched with the type of control they received, whereas students with low prior knowledge achieved better when their preference was mismatched. A significant three-way interaction on attitude reflected the same pattern found in the interaction for achievement scores. The overall results indicate that matching learner preference to the type of program they receive is an effective strategy for high-prior-knowledge students but not for those with low prior knowledge.

Critical realist review: exploring the real,beyond the empirical

This article defines the ‘critical realist review’, a literature-based methodological approach to critical analysis of health care studies (or any discipline charged with social interventions) that is robust, insightful and essential for the complexities of twenty-first century evidence-based health and social care. We argue that this approach, underpinned by a critical realist philosophy and methodology, will facilitate students and researchers to employ relevant theoretical insights from a range of disciplines that have necessary contributions to make to our understanding of health and social care practice and provision. We explore the limitations of randomised controlled trials (RCTs) and the systematic review for informing evidence-based health and social care. The article also offers some suggestions on method, although, as we argue, the approach deliberately eschews a ‘cookbook’ approach. A glossary of terms is provided in the Appendix.     

Enhancement of pigeons’ conditional discrimination performance by expectancies of reinforcement and nonreinforcement

Prior work has shown that when the separate correct responses of a conditional discrimination are followed by different reinforcing outcomes, performance is enhanced relative to that obtained under the conventional, single-reinforcer procedure. Four experiments with pigeons yielded the analogous finding when the different outcomes were reinforcement and explicit nonreinforcement. Controls indicated that the results could not be attributed to the effects of intermittent reinforcement, to possible differences in cue duration, or to a variety of potential sources of conditioned reinforcement. An interpretation in terms of expectancy learning is proposed.     

Primary pre-service teachers' pedagogical reasoning skills

This paper discusses a preliminary investigation into primary pre-service teachers' pedagogical reasoning skills. Results from this investigation led to the development of a problem-based learning model which focused on improving primary pre-service teachers' pedagogical reasoning skills. The problem-based learning model uses pedagogical reasoning as the basis for creating problem situations for the pre-service teachers to investigate. The paper reports on pre-service teachers' views on the use of the approach to improve their pedagogical reasoning skills. Specializations: science teacher education, learning in science, chemistry education. Specializations: student learning, conceptual change, technology education, curriculum evaluation.     

New Trends in Distance Learning Utilising Next Generation Multimedia Networks

Bandwidth capabilities of next generation networks have turned interactive multimedia services to a cost effective reality, targeting not only large companies, but SMEs and individual users as well. An application with direct social impact is tele-teaching and in the broader sense distance learning. A large numbers of colleges, universities, and other higher education institutions already offer online courses to their local and remote students, via new methods of education. In this paper, combining the WWW, the H.323/MPEG-4 protocol family and the CORBA model, we specify an open system and network architecture towards the Virtual Classroom realisation. Over this architecture an educational process is described using formal Object Modelling Technique (OMT) rules, while educational services are provided as methods of distributed objects. In this way, a framework is proposed in order to allow educational institutes to publish content in an abstract object-oriented manner, so as to become widely available via the well-known WWW interface.
