A systematic review characterizing and clarifying intrinsic teaching challenges linked to inquiry-based practical work     

Fru Vitalis Akuma  Ronel Callaghan 《科学教学研究杂志》2019,56(5):619-648

Since scientific literacy has become a key goal in science education, many people have argued in favor of the incorporation of inquiry in science education. However, scattered in the literature are extrinsic and intrinsic teaching challenges linked to the design and implementation of inquiry-based practical work (IBPW) in secondary school science classrooms. The purpose of this systematic literature review was to characterize and clarify the intrinsic challenges. From an instructional design perspective, the characterization of the challenges yielded four primary categories. The categories consist of initiation-phase challenges (such as unfavorable views regarding science and practical work), planning-phase challenges (including difficulties involved in designing IBPW), implementation-phase challenges (e.g., persuading learners to reflect on their experiences and findings), and summative evaluation-phase challenges which include concerns linked to the grading of practical inquiry. In the different categories, the challenges are linked to gaps in various aspects of teacher competencies especially in the context of the TPACK framework. The aspects include content knowledge (CK) (such as science content and scientific inquiry); in addition to technological knowledge (TK) linked to standard technologies. Also included is pedagogic CK (including orientation toward science teaching). Moreover, some of the intrinsic challenges are linked to gaps in skills (including pervasive classroom management and practical skills); in addition to values (such as commitment). These results have theory-, practice-, and research-based implications.  相似文献

Validating Automated Measures of Text Complexity          下载免费PDF全文

Kathleen M. Sheehan 《Educational Measurement》2017,36(4):35-43

Automated text complexity measurement tools (also called readability metrics) have been proposed as a way to help teachers, textbook publishers, and assessment developers select texts that are closely aligned with the new, more demanding text complexity expectations specified in the Common Core State Standards. This article examines a critical element of the validity arguments presented in support of proposed metrics: the claim that criterion text complexity scores developed from students’ responses to reading comprehension test items are reflective of the difficulties actually experienced by students while reading. Evidence that fails to support this assertion is examined, and implications relative to the goal of obtaining valid, unbiased evidence about the measurement properties of proposed readability metrics are discussed.  相似文献

从排名前50位的美国商学院中,随机抽取20个,把它们主页所在网站作为研究对象, 以指向网站的网页数和网络影响因子(Web-IF)作为测定核心网站的依据。研究表明:用这两种依据来测定核心网站,所得结果基本一致;Web-IF对评价网站质量和测定核心网站具有重要价值;在计算Web-IF时应以其他网站指向被研究对象的网页数和网站在该时刻可访问到的网页数作为依据;布拉德福定律可能适用于核心网站的研究。表3。参考文献11。  相似文献
