This study compared the use by 6 gifted and 6 nongifted students (ages 10 and 11) of a software package designed to develop cognitive control strategies. Bright students more often used a plan in their strategy, offered suggestions for improving the software, and monitored their own performance. (Author/DB)

Proposed is a scheme for concept development in teaching the topic of energy. Levels within the scheme are described, as well as their interrelationships and their relation to the student's own world. (KR)

Explores high school student's postinstructional knowledge about mass, volume, weight, and density in terms of what students need to know to successfully solve academic physical science problems. Presents definitions of the concepts, discusses hypothesized knowledge deficiencies, and suggests implications for instructional design. (Contains 31…

Reports on the application of technology in elementary and secondary education. The report is based on a review of the research literature and on written submissions and oral briefings from a number of academic and industrial researchers, practicing educators, software developers, and government agencies. (DDR)

Argues that there are only a few cases in which solubility and Ksp are related in a simple way. States that illustrations of the solubility product principle for one-to-one salts are adequate for students. Contains 23 references. (DDR)

Investigates variations in students' responses to lever problems across multiple assessment contexts and formats. Data sources include students' semantic maps, written responses to questions, and modeled solutions to practical problems. Contains 40 references. (DDR)

Presents the application of decision-theoretic technique to a computer-based tutoring system for elementary mechanics. Uses sound probabilistic reasoning and a student model to identify learners' misconceptions. Focuses on the integration of Bayesian belief networks, item response theory, decision analysis, and database management systems in…

Briefly summarizes methods of presenting laboratory information. Suggests that approaching lab problems requires a combination of methods structured into a problem-oriented learning experience. Focuses on the relationship of the gloxysome to the chloroplast and the steps involved in solving the problem. (DDR)

A qualitative approach was used to examine the cognitive processes students engaged in while playing recreational computer games. Participants were 21 high school students. Results indicated that players practiced complex cognitive processes such as interpreting explicit and implicit information, inductive reasoning, metacognitive analysis, and…

The experimental results of a collaborative problem solving and program development model that takes into consideration the cognitive and social activities that occur during software development is presented in this paper. This collaborative model is based on the Dual Common Model that focuses on individual cognitive aspects of problem solving and…

This article reviews didactical and psychologically based research on teachers' work and teacher thinking, narrative educational inquiry and studies of change in teachers' work and places them in the context of sociological theory about expert work and symbolic capital. The work of Abbott on the structure of expert work and knowledge, and Bourdieu…

Background: The Towers of London (TOL) and Hanoi (TOH) have been viewed as equivalent measures of planning and/or problem solving, although recent evidence in adults suggests that the underlying measurement characteristics of these two tasks may differ. As tower tasks are one of the few instruments that can be used to assess executive functioning…

The study analyses the effects of training primary school children in the use of a linguistic tool called "Exploratory Talk" (ET) on their capacity for argumentation. ET allows for reasoned confrontation and negotiation of points of view, making the reasoning visible in the talk. Eighty-eight Mexican children from the 5th and 6th grades…

Background: The executive functions of inhibition, planning, flexible shifting of actions, and working memory are commonly reported to be impaired in neurodevelopmental disorders. Method: We compared these abilities in children (8?12 years) with high functioning autism (HFA, n = 17), attention deficit-hyperactivity disorder (ADHD, n = 21) and…

This article describes an approach for introducing the unit concept in a mathematics content course designed for preservice elementary mathematics teachers. Classroom activities presented in the article emphasize the awareness, flexibility, and importance of the unit concept. Dialogue with selected preservice teachers is included and reveals some…
