Opportunities for Teacher Learning During Enactment of Inquiry Science Curriculum Materials: Exploring the Potential for Teacher Educative Materials

The development of curriculum materials that are also educative for teachers has been proposed as a strategy to support teachers learning to teach inquiry science. In this study, one seventh-grade teacher used five inquiry science units with varying support for teachers over a two-year period. Teacher journals, interviews, and classroom videotape were collected. Analysis focused on engagement in planning and teaching, pedagogical content knowledge, and the match to teacher learning needs. Findings indicate that this teacher’s ideas developed as she interacted with materials and her students. Information about student ideas, task- and idea-specific support, and model teacher language was most helpful. Supports for understanding goals, assessment, and the teacher’s role, particularly during discussions and group work, were most needed.     

Welche Rolle spielt Kompetenzdiagnostik im Rahmen von Lehr-Lernprozessen?

Competence assessment can support evidence-based teaching and learning. Depending on its specific purpose, competence assessment can be applied at the individual, the classroom or school level as well as on a national level. Large-scale-assessments are typical examples for system monitoring. Competence assessment on the individual level can provide important information with respect to individual qualification and learning outcomes. Typically, competence assessment uses psychometric models from Item-Response-Theory (IRT). However, until present, competence assessment still struggles to tap its full potential regarding feedback and individual support. Teachers often have difficulties to interpret results from competence assessments that are based on IRT. Thus, it is crucial to support teachers in using these results to improve classroom teaching. One of the main challenges of educational measurement is to align everyday classroom teaching with formative and summative assessments and to establish competence models as a common ground. Process-orientated, formative assessment can inform criterion-based feedback and, consequently, promote teaching on the basis of educational standards that were defined on the system level. However, more work needs to be done with respect to research on assessments as well as their communication and implementation into teaching practice.     

Referencing the Imaginary: An Analysis of Library Collection of Role-Playing Game Materials

The most famous role-playing game, Dungeons & Dragons, recently celebrated the fortieth anniversary of its release. The books that define the games in the role-playing genre function like sports rulebooks, contain entries like encyclopedias, or are based on collections of maps similar to those in atlases. In the library context, this places the books that define role-playing games in the domain of reference books. While currently divisions of the American Library Association encourage librarians to consider using the game in community-building and youth services, there was a time period where organized groups actively tried to discourage librarians from collecting materials associated with the genre. This study is an assessment of library holdings of role-playing game materials worldwide, detailing collection and cataloging issues associated with the genre.     

Caveats for using statistical significance tests in research assessments

This article raises concerns about the advantages of using statistical significance tests in research assessments as has recently been suggested in the debate about proper normalization procedures for citation indicators by Opthof and Leydesdorff (2010). Statistical significance tests are highly controversial and numerous criticisms have been leveled against their use. Based on examples from articles by proponents of the use statistical significance tests in research assessments, we address some of the numerous problems with such tests. The issues specifically discussed are the ritual practice of such tests, their dichotomous application in decision making, the difference between statistical and substantive significance, the implausibility of most null hypotheses, the crucial assumption of randomness, as well as the utility of standard errors and confidence intervals for inferential purposes. We argue that applying statistical significance tests and mechanically adhering to their results are highly problematic and detrimental to critical thinking. We claim that the use of such tests do not provide any advantages in relation to deciding whether differences between citation indicators are important or not. On the contrary their use may be harmful. Like many other critics, we generally believe that statistical significance tests are over- and misused in the empirical sciences including scientometrics and we encourage a reform on these matters.     

Examining Measure Correlations With Incomplete Data Sets

A 2-stage procedure for estimation and testing of observed measure correlations in the presence of missing data is discussed. The approach uses maximum likelihood for estimation and the false discovery rate concept for correlation testing. The method can be used in initial exploration-oriented empirical studies with missing data, where it is of interest to estimate manifest variable interrelationship indexes and test hypotheses about their population values. The procedure is applicable also with violations of the underlying missing at random assumption, via inclusion of auxiliary variables. The outlined approach is illustrated with data from an aging research study.     

Solutions in global software engineering: A systematic literature review

Global software engineering (GSE) has received increased attention, as globalization enables and encourages increased distribution of product development. Many empirical studies and systematic literature reviews (SLRs) focus on the identification of challenges, this paper however presents the first SLR collecting and analyzing solutions associated with GSE, while also evaluating the level of empirical validation of said solutions. As a starting point the paper presents a GSE model, designed to categorize solutions into process areas, useful for the analysis of the research community's contributions to state-of-the-art and identifying fundamental gaps in research. In addition, the model categorizing the solutions is populated with references and good-examples, useful for practitioners, which can use the model to find solutions to overall challenges in various process areas. The overall results of the systematic review revealed more than 330 papers containing 127 solutions that were then identified and mapped to the model. The process areas of project management are highly populated, while other areas like product integration have received surprisingly little attention. In addition, selected process area is elaborated upon in terms of contents and deficiencies.     

Visual attention in orienteers at different levels of experience

Abstract

This study explored how differences in orienteering experience are related to differences in how visual attention is allocated to the map, the environment and to travel. Twenty more experienced and 20 less experienced individuals orienteered while wearing a head-mounted video camera with microphone. The participants verbalized what they were attending to (map, environment or travel) at any given time. Each recorded film was coded at each point in time in terms of what the participant was attending to and whether the participant was moving or stationary. More experienced orienteers attended to the map markedly more while moving and spent less time stationary than less experienced orienteers. The participants' performance was significantly related to the ability to attend to the map while moving. The strategic control of attention is proposed to explain this ability. It is proposed that attentional training might enhance performance in sports characterized by multiple and dynamically varying elements.     

‘Get real – we can't afford kindergarten’: a study of parental perceptions of early years services

The Australian Early Childhood Universal Access Agreement stipulates all children three and a half years of age and older access to 15 hours of a quality early childhood education programme. While most states and territories in Australia have a 90% or higher attendance rate, in 2010, in Queensland the attendance rate was a comparative 40%. This study explores parental perceptions of barriers to early years services in Queensland, Australia. Using content analysis, it explores comments from an online forum with 65 self-selected participants. Findings provide important insights for policy-makers interested in improving the quality of, access to, and participation in, early childhood education. Parents perceived the cost, limited number of places and small hours of kindergarten as the main barriers to accessing quality early childhood care in Queensland. Furthermore, they questioned the actual necessity of kindergarten programmes. Therefore, if the goal is to improve kindergarten attendance rates, it is important to gain an understanding of the reported perceived barriers in order to reduce these in the future.
