The role of values in pre-service teachers’ intentions for professional engagement

This study investigated inclusion of epistemic value into Richardson and Watt Factors Influencing Teaching Choice (FIT-Choice) framework to produce a more robust, useful teacher motivation model. We specifically examined pre-service teachers’ social utility value (SUV), personal utility value (PUV) and epistemic value regarding pursuing future professional engagement and development. Using principal axis factoring, we found four main factors: PUV, SUV, epistemic value—future value of knowledge (EVF) and persistence/satisfaction. These factors were then used in a structural equation model (SEM) to predict pre-service teachers’ intentions to pursue future professional engagement. Results provided the following three insights: (a) SUV was the most consistent, positive predictor of professional engagement and predicted all dependent variables; (b) EVF was a newly identified factor and a positive predictor of pre-service teachers’ desire to pursue a leadership position and (c) PUV negatively predicted planned effort and a desire to pursue a leadership position.     

Developing conceptions of food and nutrition

This paper describes an investigation of concepts that various groups hold about food and nutrition. Groups investigated were students in Years 4 and 8, university students in a BEd (primary) program and parents of the Year 4 students. It was found that for many important concepts relating to food selection, the basic ideas of each group were surprisingly consistent, despite the influence of formal education. In particular, misconception about energy and its role in nutrition and particular food groups was an important finding. Implications for school and community education are drawn from the results. Specialization: science curricula.     

A Qualitative Analysis of the Immediate and Short-term Impact of an Environmental Interpretive Program

This study utilized qualitative measures to further understand if an environmental interpretive experience can enhance an environmental ethic. A discursive approach to emergent design was used to generate grounded theory (Strauss & Corbin, 1990). In the methods used, the phenomenological data gathered during the study directed the design of each step of the research as it evolved. Twenty-four 4th graders were randomly selected from three classes from a rural town in southern Indiana (USA). These students participated in a field trip to a US Forest Service site near their school district. Methodologies utilized in this program included ranger-led discussions, facilitated explorations, and nature 'games'. The data was collected through post interviews (1 week following treatment) and post post interviews (4 months after program). The findings indicated that the environmental interpretive program had a strong positive impact on students' affect toward the resource site. The findings also indicated retention of game mechanics and the content imbedded in these games. Cognitive and behavioral impacts were limited.     

Generative mechanistic explanation building in undergraduate molecular and cellular biology*

ABSTRACT

When conducting scientific research, experts in molecular and cellular biology (MCB) use specific reasoning strategies to construct mechanistic explanations for the underlying causal features of molecular phenomena. We explored how undergraduate students applied this scientific practice in MCB. Drawing from studies of explanation building among scientists, we created and applied a theoretical framework to explore the strategies students use to construct explanations for ‘novel’ biological phenomena. Specifically, we explored how students navigated the multi-level nature of complex biological systems using generative mechanistic reasoning. Interviews were conducted with introductory and upper-division biology students at a large public university in the United States. Results of qualitative coding revealed key features of students’ explanation building. Students used modular thinking to consider the functional subdivisions of the system, which they ‘filled in’ to varying degrees with mechanistic elements. They also hypothesised the involvement of mechanistic entities and instantiated abstract schema to adapt their explanations to unfamiliar biological contexts. Finally, we explored the flexible thinking that students used to hypothesise the impact of mutations on multi-leveled biological systems. Results revealed a number of ways that students drew mechanistic connections between molecules, functional modules (sets of molecules with an emergent function), cells, tissues, organisms and populations.     

Emotions about Teaching about Human-Induced Climate Change

Global climate change is receiving increasing attention as a classroom topic. At the same time, research has shown that individuals have strong emotions about the topic. Emotions about controversial topics and individuals' dispositions toward knowledge have been shown to influence judgments about these topics. This study examined the relationships among preservice elementary and in-service secondary science teachers' emotions about and plausibility perceptions of climate change, background knowledge of weather and climate distinctions (a principle related to understanding climate change), and dispositions toward knowledge. Teachers' topic emotions (anger and hopelessness) were significant predictors of plausibility perceptions, with more anger associated with lesser plausibility and greater hopelessness associated with higher plausibility. Decisiveness—an urgent desire to reach closure—was also significantly related to plausibility perceptions with greater decisiveness associated with reduced plausibility perceptions. In-service secondary teachers who do not currently teach about climate change exhibited greater anger and decisiveness than preservice elementary teachers and in-service secondary teachers who do teach about climate change. Implications for climate literacy education are discussed.     

Rhythmicity and Preperformance Ritual: Stabilizing a Flexible System

Abstract

The purpose of this study was to determine: (a) if preperformance behaviors display a consistent rhythm across disparate activities; and (b) the relationship of periodicity for such preperformance routines to successful performance. Seven male volunteers were subjects for this study. Each subject had an established ritual for golf putt, basketball free throw, and tennis serve. Data were collected with a motion-analysis system and video camera while the subjects performed each activity. Dependent measures were types of preperformance behaviors, absolute timing of behaviors, relative timing of behaviors, differences in relative times across activities, and successful performance, and mechanical variables related to performance. Analysis of variance (Subject x Activity) indicated significant main effects and interactions for absolute and relative timing of behaviors. Significant correlations were determined to exist between relative time and success, and differences were found between relative times across activity and successful performance. It was concluded that rituals result from endogenous rhythms and that stable periodicity of behaviors across activities promotes successful performance.     

Interrater Objectivity for Field-Based Fundamental Motor Skill Assessment

We recently published an article on arm coordination and performance level in 400-m front-crawl swimming in Research Quarterly for Exercise and Sport (Schnitzler, Seifert, &; Chollet, 2011). The index of coordination (IdC) was used to quantify interarm coordination. Our results showed that expert swimmers exhibited lower IdC than recreational swimmers over a 400-m trial. In addition to criticizing various methodological points, Havriluk (2012) challenged our conclusion that catch-up could be an efficient model of coordination and instead suggested that it might lead to injuries. An important point in this debate, however, is that our definition of catch-up coordination may differ from the one proposed by Havriluk (2012), which would explain why we consider catch-up coordination to be the dominant mode of coordination used by expert swimmers during training sessions.
