In this paper, we analyze an investigative situation proposed to a class of 5th graders in a primary school. The situation is based on the following task: In a sale with group rates on a sliding scale, the students must find the lowest possible purchase price for a given number of tickets. A study of students' arguments made it possible to…

The cognitive load and learning effects of dual-code and interactivity--two multimedia methods intended to promote meaningful learning--were examined. In Experiment 1, college students learned about the causal chain of events leading to the process of lightning formation with a set of words and corresponding pictures (Group WP), pictures (Group…

This paper is based on a multiple-case study of the learning process in three asynchronous computer conferences. The conferences were part of the distance learning component in doctoral degree courses in computing technology in education offered at an American university. The conferences were analyzed from a number of perspectives, the emphasis in…

The article discusses a vast river of data or information and creating a context in which the information makes sense and can be understood. As technologists, they have this kind of awkward responsibility to deal with social context. In order to provide value to their organizations, they need to understand the messy activity of groups of people…

Drawing on a wide range of secondary and primary materials as well as personal experience of Albania dating from the 1970s to the present day, this paper describes and critically evaluates current geographical and environmental education in Albania in relation to three dimensions: (1) the changing nature of the curriculum over the past 20 years;…

This paper articulates a perspective on learning to discuss ways in which students develop personal sense and negotiate meaning in a middle school algebra context. Building on a sociocultural perspective that incorporates mental objects, learning is described as a mutually dependent process involving personal sense making and the public…

Despite the increasing importance of, and interest in, documenting the impact of environmental education programs on students' learning for sustainability, few tools are currently available to measure young students' environmental learning across all the dimensions of knowledge, skills, attitudes and behaviours. This paper reports on the…

Cannabinoid receptors type 1 (CB1) play a central role in both short-term and long-term extinction of auditory-cued fear memory. The molecular mechanisms underlying this function remain to be clarified. Several studies indicated extracellular signal-regulated kinases (ERKs), the phosphatidylinositol 3-kinase with its downstream effector AKT, and…

At University High School, an alternative high school for students who failed in the Boston Public Schools system, everyone is learning to implement the more dynamic, socially conscious, and relevant way of learning by doing. Students, teachers, and staff are learning how to develop an educational philosophy and practice that is predicated on…

As online collaborative technologies become easier to use, an increasing range of "virtual communities" are being established, often for educational purposes. This report stresses that an efficient technology is only part of the process underlying a successful online community. It considers the social process on which an online learning community…

An artfully designed, 3-D computer-generated video story was created to demonstrate the mixing of primary colors to obtain secondary colors. Two research questions were explored in this research: Do artfully designed 3-D computer-generated video stories enhance learning or are such entertaining works a distraction from learning? And, do children…

Learning object design currently leads the instructional technologist towards more effective instructional design, development, and delivery of learning content. There is a considerable amount of literature discussing the potential use of learning object in e-learning. However, most of the works were mainly focused on the standard forms of…

This article outlines a conceptualization of personality as a cognitive-affective processing system (CAPS) and explores its implications for understanding disorders and pursuing therapeutic change. The CAPS conception of personality was proposed in 1995 in order to resolve a long-standing paradox in personality and social psychology, namely, the…

In architecture courses, the bridging of design learning and construction is a constant challenge for educators. When designing the construction details of a building, students lack the field/site experience of the construction process and an understanding of the problems and solutions associated with erecting a building. The degree of…

Organizations value the business impact and benefits that accompany e-learning, such as workforce effectiveness, reduced training costs, and improved workforce retention (Taylor, 2001). However, although justifying the value of evaluation is clear, "e-learning evaluations often do not receive the priority that they deserve" (Tanquist, 2000, p. 1).…
