ABSTRACTPromoting preservice science teachers’ experimentation competency is required to provide a basis for meaningful learning through experiments in schools. However, preservice teachers show difficulties when experimenting. Previous research revealed that cognitive scaffolding promotes experimentation competency by structuring the learning process, while metacognitive and multimedia support enhance reflection. However, these support measures have not yet been tested in combination. Therefore, we decided to use cognitive scaffolding to support students’ experimental achievements and supplement it by metacognitive and multimedia scaffolds in the experimental groups. Our research question is to what extent supplementing cognitive support by metacognitive and multimedia scaffolding further promotes experimentation competency. The intervention has been applied in a two-factorial design to a two-month experimental course for 63 biology teacher students in their first bachelor year. Pre-post-test measured experimentation competency in a performance assessment. Preservice teachers worked in groups of four. Therefore, measurement took place at group level (N?=?16). Independent observers rated preservice teachers’ group performance qualitatively on a theory-based system of categories. Afterwards, experimentation competency levels led to quantitative frequency analysis. The results reveal differing gains in experimentation competency but contrary to our hypotheses. Implications of combining scaffolding measures on promoting experimentation competency are discussed. 相似文献

Factors associated with school behavioral competence at 72 months were investigated in a sample of at-risk boys followed longitudinally from 18 months. Boys were at risk for developing behavior problems due to early exposure to sociodemographic and family-environmental stressors associated with low-income urban living. Research findings: Of child protective factors investigated, main effects were found for intelligence, mother-reported emotionality and sociability, and observed likability in relation to teacher-reported behavior problems, and results were generally consistent across type of risk. In only one instance did the effect of a protective factor depend on the level of risk. Furthermore, a cumulative measure of protective factors was strongly predictive of child behavior problems and was a better predictor than cumulative risk measures. Observed infant emotionality, child physical attractiveness, and children's self-perceptions of being pro-social or aggressive and fearless were essentially unrelated to behavioral outcome. Mother-reported child emotionality mediated both the relation between mother-reported infant emotionality and teacher-reported internalizing problems, and the relation between observed likability and teacher-reported externalizing problems. Practice/Policy: Clinical implications concern improved identification accuracy of at-risk children who should be targeted for intervention, and forms that intervention should take. 相似文献

Students learning to read in more than one language are a growing population in schools. Early screening and identification of reading difficulties may lead to better outcomes for all students. Oral reading fluency (ORF) is one tool shown to be both a reliable measure of reading and an accurate method to identify students at risk for poor reading outcomes. This study synthesized available validity evidence for ORF with biliterates. All included studies (n = 31) were conducted with English language learners in grades K–8. Results suggested that although ORF is correlated with reading outcomes, the accuracy of ORF to identify English learners at risk of poor reading outcomes does not meet criteria. The strength of validity evidence differed by language proficiency of participants. Finally, the quality of the reviewed studies was low in critical areas. 相似文献

Abstract This article introduces the Partnership for Shared Book Collections, a federation of monograph shared print programs. Collaboration of programs at the network level allows for:
-
Reducing the cost of retaining the scholarly record through shared distribution of commitments;
-
De-duplicating efforts;
-
Developing and promoting evidence-based best practices;
-
Increasing the effectiveness of communication with end-users and funders;
-
Tackling large-scale projects and research that are out of reach for individual shared print programs. This shared stewardship of collection is critical as local resources are depleted due to the COVID-19 pandemic and access to print for digitization increases.

Many academic libraries rely on a student workforce for everyday operations, interacting with patrons, and assistance with larger projects. Training these students for such multifaceted and customer-service-focused positions can be a challenge. This article traces an overhaul of training procedures made during the transition to a centralized, services desk workflow. All aspects of training a large student workforce, from planning and presentation to assessment, are outlined. Interactive group sessions and peer-to-peer reinforcement of procedures have proven to be most effective in training student workers for varied roles in an academic library. 相似文献

ABSTRACTLibrary Services Platforms (LSPs) offer academic libraries the ability to integrate the management of print and electronic resources in one centralized platform. This article will examine the role of electronic resources librarians (ERLs) in a large-scale, consortial LSP implementation relative to NASIG’s Core Competencies for Electronic Resources Librarians. The speakers, Conor Cote and Kirsten Ostergaard, hail from Montana, where the Treasure State Academic Information and Library Services Consortium, comprised of seventeen academic libraries, is implementing Ex Libris’s Alma LSP in conjunction with the Primo discovery layer. The aim of this presentation and article is to examine how the skills and competencies of an ERL can be leveraged for an effective and minimally disruptive LSP implementation. 相似文献
