This study investigated the impact of three commonly used cardiovascular model-assisted activities on student learning and student attitudes and perspectives about science. College students enrolled in a Human Anatomy and Physiology course were randomly assigned to one of three experimental groups (organ dissections, virtual dissections, or…

We present a simple and accurate experiment to obtain the speed of sound in air using a conventional speaker and a microphone connected to a computer. A free open source digital audio editor and recording computer software application allows determination of the time-of-flight of the wave for different distances, from which the speed of sound is…

In this paper we describe a touchscreen application called "TouchCounts," which is designed to support the development of number sense in the early years. We first provide an a priori analysis of its affordances. Then, using Sfard's communicational approach, augmented by a focus both on the role of the body--particularly the fingers…

This article presents the perspectives of science and mathematics teachers on their use of information and communication technology (ICT) in teaching and learning in Tanzania. The findings show that few teachers used computers for teaching and learning purposes while majority of them used computers for administrative purposes. Additionally,…

Pre-service teachers' self-reported intentions to use information technology were studied. Two hundred and sixty-four participants completed a survey questionnaire measuring their responses to four constructs (performance expectancy, effort expectancy, social influence and facilitating conditions) derived from the Unified Theory of Acceptance and…

This article outlines reasons to use (or not use) the Internet in English language teaching, exploring the Internet as tutor and tool. Discussion of Internet content includes types of content and how to select, save, and use content. Various learning tasks, appropriate even for those without Internet access, are presented and highlighted in a…

In massive open online courses (MOOCs), low barriers to registration attract large numbers of students with diverse interests and backgrounds, and student use of course content is asynchronous and unconstrained. The authors argue that MOOC data are not only plentiful and different in kind but require reconceptualization--new educational variables…

According to the relevance of teacher attitudes in the teaching process as well as to the great number of discussions among experts of pre-school education, it was interesting to examine the students of pre-school teaching about their attitudes toward the use of computer among pre-school children. The sample consisted of N = 40 students from…

This paper proposes and discusses how to use an assignment based on "Freakonomics" as a way to foster critical thinking and statistical literacy skills within the classroom.

Learning journal writing is an effective tool to foster the development of reflective capacity in the context of Vocational Education and Training (VET) if conceived as a collection of descriptions and reflections on real professional experiences. Reporting professional situations in a learning journal outside the workplace in turn fosters the…

Schools are scrambling to prepare students for the writing assessments aligned to the Common Core State Standards. In some states, writing has not been assessed for over a decade. Yet, with the use of computerized grading of the student's writing, many teachers are wondering how to best prepare students for the writing assessments that will…

This experiment combined controlled experimental design with a best-practice approach (i.e., real course content, subjective evaluations) to clarify the role of verbal redundancy, confirm the multimodal impact of images and narration, and highlight discrepancies between actual and perceived understanding. The authors presented 1 of 3…

For more than 2 years, Scratch programming has been taught in Taiwanese elementary schools. However, past studies have shown that it is difficult to find appropriate learning methods or tools to boost students' Scratch programming performance. This inability to readily identify tutoring tools has become one of the primary challenges addressed in…

This study examined the effectiveness of using the online digital reading environment to increase elementary students' comprehension within a reading clinic. Preservice teachers at a four-year university in the Midwest worked one-on-one with 58 fourth-grade students from three schools who were assigned to one of three conditions: print-based text…

This Core Data Service (CDS) Spotlight focuses on public computing resources, including lab/cluster workstations in buildings, virtual lab/cluster workstations, kiosks, laptop and tablet checkout programs, and workstation access in unscheduled classrooms. The findings are derived from 758 CDS 2012 participating institutions. A dataset of 529…
