Life on the borderlands: action research and clinical teacher education faculty

Seeking to soften the gap between clinical and tenure-track teacher education faculty, a year-long action research seminar was conducted. Using data from observation notes, interviews and a taped seminar session, the authors explore the seminar from its very rocky beginning to its conclusion. Drawing on the concept of ‘communities of practice’, the authors explore reasons for the hesitancy of the clinical faculty to share the results of their studies and their struggle to find legitimacy within the university.     

Dimensions of test performance in English as a foreign language in different European settings: a two-level confirmatory factor analytical approach

The present study explored data from a survey of students’ performance in English at the end of compulsory school in 6 European countries. The aim was to gain deeper knowledge of the internal structure of the test and to discuss similarities and differences between the different settings regarding patterns in language proficiency. The analyses, conducted by a factor analytic approach and 2-level structural equation modelling (SEM) techniques, indicated an overall English achievement factor at both student and school levels. Furthermore, an effect of format differences at the student level, constituted by a factor related to tasks demanding constructed response, was found. Three correlated modality factors related to listening, linguistic, and reading skills were identified but not further elaborated on as they improved the model only modestly. Considerable differences in between-school variation were found in the different settings. The results are discussed in relation to the instrument, student achievements, and the state of English in the participating countries.     

Teacher Professional Development Through a Collaborative Curriculum Project – an Example of TPACK in Maine

Maine’s one-to-one laptop program provides an ideal opportunity to explore conditions that optimize teacher integration of technology-focused curriculum into the classroom. EcoScienceWorks (ESW) is an ecology curriculum that includes targeted simulations and a code block programming challenge developed through an NSF-ITEST grant. The project was designed as a collaboration that included simulation software developers; middle school science teachers; the Maine laptop program; environmental educators; an external evaluator; and a lead organization experienced in teacher guided curriculum development. Thus, each of the elements of TPACK (technology, pedagogy, and content knowledge) worked together to produce the final ecology simulation-centered curriculum. In 2008–2009, the ESW curriculum became available statewide through the Maine laptop program. Partner teachers have transitioned their classrooms to more learning-centered environments through the use of technology and have become teacher leaders. The collaborative approach to technology focused curriculum development used in this project is a model for TPACK professional development.     

Sensing the Coherence of Biology in Contrast to Psychology: Young Children's Use of Causal Relations to Distinguish Two Foundational Domains

To what extent do children understand that biological processes fall into 1 coherent domain unified by distinct causal principles? In Experiments 1 and 2 ( N  =   125) kindergartners are given triads of biological and psychological processes and asked to identify which 2 members of the triad belong together. Results show that 5-year-olds correctly cluster biological processes and separate them from psychological ones. Experiments 3 and 4 ( N  =   64) examine whether or not children make this distinction because they understand that biological and psychological processes operate according to fundamentally different causal mechanisms. The results suggest that 5-year-olds do possess this understanding, and furthermore, they have intuitions about the nature of these different mechanisms.     

Evaluating change in interagency collaboration of a state-level interagency education team: a social network approach within a utilization-focused framework

Improving collaboration among organizations is a goal of interagency educational teams, but collaboration is typically thought of as an ambiguous concept that cannot be quantified. To assess the collaborative strength of a state-level interagency team in a Midwestern state, team members completed the Levels of Collaboration Scale (Frey et al., American Journal of Evaluation 27(3):383, 2006) for three consecutive years. The team members then utilized the results of the social network analysis to support and sustain collaborative efforts. Findings revealed that the number of partnerships increased and the depth of collaboration expanded across the 3 years. Social network analysis results were utilized to develop collaboration strategies, thus influencing the expansion of the network across the 3-year period.     

A micropillar array for sample concentration via in-plane evaporation

We present a method to perform sample concentration within a lab-on-a-chip using a microfluidic structure which controls the liquid-gas interface through a micropillar array fabricated in polydimethylsiloxane between microfluidic channels. The microstructure confines the liquid flow and a thermal gradient is used to drive evaporation at the liquid-gas-interface. The evaporation occurs in-plane to the microfluidic device, allowing for precise control of the ambient environment. This method is demonstrated with a sample containing 1 μm, 100 nm fluorescent beads and SYTO-9 labelled Escherichia coli bacteria. Over 100 s, the fluorescent beads and bacteria are concentrated by a factor of 10.     

Attitudes and Communications about Wildlife

Abstract

In order to determine the effects of sex, grade level, region, and academic preparation on energy opinions, selected items from Kuhn's revision of Wert's Energy Opinionnaire were constructed into a criterion measure on total score and three sub-scale scores. The Ss were 251 secondary school students from two regions of the country and an academically prepared class of secondary students enrolled in a course entitled “Science and the Economics of Energy.” The data were analyzed first to compare selected chi-square results of the study with results reported by Kuhn and to compare Alpha Statements. The second phase included the use of ANOVA and Scheffe Comparisons. In general, there were significant differences in ANOVA results by sex, region of the country and, to some extent, academic preparation. There were no significant results by grade level or conservation.     

Conducting Video Research in the Learning Sciences: Guidance on Selection,Analysis, Technology,and Ethics

Linking research to a compelling societal interest can build financial commitments to research, bring increased attention to findings, and grow support for scaling up impacts. Among many compelling societal interests that learning scientists can cite—such as increasing the quality of life, preparing citizens to make decisions in a complex world, and enhancing social cohesion among a diverse population—economic competitiveness is a compelling societal interest that resonates broadly among stakeholders. Indeed, it is now somewhat common to introduce learning sciences research, as in the Cambridge Handbook of the Learning Sciences and the U.S. National Education Technology Plan, by citing economic rationales. Despite the utility of evoking a potential link between learning research and economic competitiveness in the minds of broader audiences, learning scientists engage in rather little critical discussion of whether such links are meaningful and empirically sound within their own programs of research. This article seeks both to problematize conventional wisdom about links between learning sciences research and economic growth and to suggest possible directions for future research aimed at discovering stronger links. Because the issues are complex, we do not reach firm conclusions. Rather, this article seeks to spark a discussion within the field.     

Additive and disruptive pedagogies: The use of slowmation as an example of digital technology implementation

The purpose of this study was to explore the experiences of 35 preservice teachers as they were introduced to a new digital technology, “Slowmation” (abbreviated from Slow Animation), as a “disruptive” pedagogy over a period of 12 months. The participants in the study were 35 preservice teachers from an elementary cohort. Primary data sources included field notes and semi-structured interviews. Findings revealed that the preservice teachers enjoyed using slowmation as learners during the on-campus part of their program, yet very few used it as a disruptive pedagogy when teaching during their extended practicum. Our study highlights the challenges inherent in introducing “disruptive” pedagogies in a teacher education program.     

Force– and power–time curve comparison during jumping between strength-matched male and female basketball players

The purpose of this study was to compare force– and power–time curve variables during jumping between Division I strength-matched male and female basketball athletes. Males (n?=?8) and females (n?=?8) were strength matched by testing a one-repetition maximum (1RM) back squat. 1RM back squat values were normalised to body mass in order to demonstrate that strength differences were a function of body mass alone. Subjects performed three countermovement jumps (CMJ) at maximal effort. Absolute and relative force– and power–time curve variables from the CMJs were analysed between males and females. Average force– and power–time curves were generated for all subjects. Jump height was significantly greater (p?≤?.05) in males than females. Absolute force was higher in males during the concentric phase, but not significantly different (p?≥?.05) when normalised to body mass. Significance was found in absolute concentric impulse between sexes, but not when analysed relative to body mass. Rate of force development, rate of power development, relative peak force, and work were not significantly different between sexes. Males had significantly greater impulse during the eccentric phase as well as peak power (PP) during the concentric phase of the CMJ than did females in both absolute and relative terms. It is concluded that sex differences are not a determining factor in measured force during a CMJ when normalised to body mass between strength-matched subjects. However, eccentric phase impulse and concentric phase PP appear to be influenced by sex differences independent of matching strength levels.
