This study describes the multiple analogical models used to introduce and teach Grade 12 chemical equilibrium. We examine the teacher's reasons for using models, explain each model's development during the lessons, and analyze the understandings students derived from the models. A case study approach was used and the data were drawn from the…

This study investigates the influence of using five web-based practice units on English verb-noun collocations with the design of a web-based Chinese-English bilingual concordancer (keyword retrieval program) on collocation learning. Thirty-two college EFL students participated by taking a pre-test and two post-tests, and responding to a…

Many topics in chemistry are difficult for learners to understand, including symmetry. Reasons for this difficulty include its multi-level content, instructional methodologies utilized, and learner variables. This study examined the effect of initial instructional modality and prior knowledge on learning of point group symmetry. Forty-four…

Despite a century of research, the mechanisms underlying short-term or working memory for serial order remain uncertain. Recent theoretical models have converged on a particular account, based on transient associations between independent item and context representations. In the present article, the authors present an alternative model, according…

This paper sets out to examine the impacts of schooling and health knowledge on the level of obesity in Taiwan. The results obtained from a sample of Taiwanese females support the hypothesis of Grossman that schooling has a direct positive effect on health by reducing the likelihood of a person being obese. The awareness of obesity-disease…

This study compares the effects of forum discussion with metacognitive guidance versus forum discussion without metacognitive guidance (Forum) on solving real life mathematical tasks and self-regulated learning. Participants were 43 Grade 7 students (boys and girls) who practiced online problem-solving in two classes. The metacognitive guidance…

It has recently been determined that generating an explanatory hypothesis to explain a discrepant event is important for students' conceptual change. The purpose of this study is to investigate how students' generate new explanatory hypotheses. To achieve this goal, questions are used to identify students prior ideas related to electromagnetic…

Beginning teachers in Northern Ireland and the United States conducted structured inquiry projects in which they investigated elementary children's understanding of history and social studies. Interviews with the teachers and analysis of their written assignments indicate that these investigations challenged their beliefs about children's prior…

The purposes of this study were to determine the actual amount of instructional time spent on social studies, to determine the variety of instructional strategies used during social studies instruction, and to assess the frequency and types of technology usage during social studies instruction. As part of addressing the No Child Left Behind Act, a…

The part played by tacit skills and knowledge in work performance is well recognised but not well understood. These implicit or hidden dimensions of knowledge and skill are key elements of "mastery," which experienced workers draw upon in everyday activities and continuously expand in tackling new or unexpected situations. This paper,…

Recent papers document that student problem-solving competence varies (often strongly) with representational format, and that there are significant differences between the effects that traditional and reform-based instructional environments have on these competences [Kohl and Finkelstein, Phys. Rev. ST Phys. Educ. Res. 1, 010104 (2005); Kohl and…

The focus of this article is on the learning and teaching processes of six teacher candidates, made possible by the study of a work of art in their internship placement. The interns observed and worked closely with two Lincoln Center Institute (LCI) music Teaching Artists (TAs) and six classroom teachers to provide students in kindergarten through…

The authors investigated in this study the effects of two electronic notes conditions (complete vs. partial) and two testing conditions (immediate vs. delayed) on three types of tests (fact, structure, and application). A 2 x 2 factorial multivariate analysis of variance (MANOVA) yielded no significant main effects for notes conditions on the fact…

To counter user disorientation and cognitive overload, hypertext environments often incorporate navigational aids in the form of graphical overviews of the hypertext structure. The aim of the present experimental investigation of learning in hypertext environments was to examine the impact of such graphical overviews on learning achievement in…

In this article, the author shares the lessons he learned from Aaron, a 12-year old kid who had never been to school, on the importance of crafting systematic fluency lessons. The following are strategies that worked for them: (1) Demonstrate what fluency sounds and feels like; (2) Read aloud to the students at least three times a day from a…
