This paper focuses on the potential of mental simulation (mentally rehearsing an action to enhance performance) as a useful contemporary educational method. By means of a meta-review, it is examined which conditions impede or facilitate the effectiveness of mental simulation (MS). A computer search was conducted using Ovid PsycINFO. Reviews,…

The present study is part of a project aiming at empirically investigating the process of modeling the partner's knowledge (Mutual Knowledge Modeling or MKM) in Computer-Supported Collaborative Learning (CSCL) settings. In this study, a macro-collaborative script was used to produce knowledge interdependence (KI) among co-learners by providing…

Utility companies generate three-phase electric power, which consists of three sinusoidal voltages with phase angles of 0 degrees, 120 degrees, and 240 degrees. The ac generators described in most introductory textbooks are single-phase generators, so physics students are not likely to learn about three-phase power. I have developed a simple way…

In this note we show the existence of a surprising analogy between quadrilaterals and tetrahedra, determining some properties that hold for both families of figures. This analogy suggests some new properties of quadrilaterals. (Contains 11 figures,)

Background/Context: Concerns about instructional quality have unleashed a frenzy of reform efforts, including changes in school governance, teacher recruitment, and curriculum, modification of teaching philosophies and procedures, stricter accountability management, and increased quests for scientific research information and guidance. These…

The television show Deal or No Deal and an Excel spreadsheet help students see how understanding probability and mean--and the concept of expected value (EV)--can lead to game show wins.

The study reported in this article deals with the observed actions of Turkish pre-service mathematics teachers in dynamic geometry environment (DGE) as they were learning Khayyam's method for solving cubic equations formed as x[superscript 3] + ax = b. Having learned the method, modelled it in DGE and verified the correctness of the solution,…

This article analyzes the findings from an 18-section experiment studying the effect of homework-completion tutoring on community college students' remedial mathematics performance. The experiment involved 529 students registered for two remedial math courses: math skills and algebra. For each course, the experiment studied nine sections: three…

Evidence of the increasing use of technology in counselor education is indicated by the increase in journal articles, programs, websites, and books on this topic (Albrecht & Jones, 2001; Layne & Hohenshil, 2005). The Internet has emerged as an important tool in the training and supervision of counseling students (Conn, Roberts, & Powell, 2009;…

The purpose of this case study was to identify characteristics of learners who completed their master's degrees online and to explore the reasons adult learners chose to enroll in a particular institution to complete their online master's degrees. As more postsecondary institutions explore the online environment, more research-based information is…

This research examined teachers' online behaviors while using a digital library service--the Instructional Architect (IA)--through three consecutive studies. In the first two studies, a statistical model called latent class analysis (LCA) was applied to cluster different groups of IA teachers according to their diverse online behaviors. The third…

This paper analyses the role of Computer Algebra Systems (CAS) in a model of learning based on competences. The proposal is an e-learning model Linear Algebra course for Engineering, which includes the use of a CAS (Maxima) and focuses on problem solving. A reference model has been taken from the Spanish Open University. The proper use of CAS is…

Introduction: The aim of our research was to investigate the modality effect in more detail by measuring it in a direct way. Two studies were conducted using the same subject and material. Method: Computer-based learning material was presented on several screens, each containing a short text and a picture. Modality was varied by presenting written…

The present paper discusses results of a study which aimed to explore the knowledge and use of Web 2.0 technologies by LIS academics in Iran and to explore the challenges they face for using these technologies. The research method was explorative and empirical. Data was collected through a web-based survey questionnaire containing both open and…

This article deals with gender phenomena in the context of digital literacy. Studies show that computer use, computer skills, and computer-related self-concepts are subject to gender differences. These differences may affect classroom interactions as well as learning processes and have therefore to be considered carefully by teachers who apply…
