Discussion of technological problem-solving skills focuses on a study of Israeli seventh graders' work while engaged in design tasks within an unstructured learning environment. Reports on the evaluation/modification cycles, including conceptual constituents of the cycles; students' decisions regarding the original design goals; and the…

Describes a study of graduate distance education students that defined and measured collaboration during asynchronous computer-mediated communication using a threaded Web discussion. Developed a model for evaluating interdependence, synthesis, and independence in collaboration; and discusses the role of collaboration in problem solving, along with…

Experiments in strategy instruction for mathematics have been conducted using three models (direct instruction, self-instruction, and guided learning) applied to the tasks of computation and word problem solving. Results have implications for effective strategy instruction for learning disabled students. It is recommended that strategy instruction…

Outlines a possible framework for allowing teachers to explore how children learn mathematics. A mathematical modelling process and three domains, including content, process and pragmatic domain, are described. Twelve strategies for encouraging children to translate between the domains are suggested. (YP)

Discussion of the diffusion of interactive communications innovations focuses on the integration of telecomputing tools into precollege curricula. Topics include the telecomputing teacher as instructional designer; a models approach to instructional design; and telecomputing activity structures, including interpersonal exchanges, information…

This article reviews common curricular alternatives for addressing the science education needs of secondary students with learning disabilities. A curriculum revision method emphasizing models and context-rich problem solving is proposed as an alternative to the traditional uses of direct instruction, mnemonics, graphic organizers, and study…

Demonstrates and compares three commercially available statistical software packages, Statistics Workshop, Data Insights, and Data Desk, using a five-component investigation model to analyze a problem about hat sizes. (MKR)

Beliefs about mathematics of 26 junior and senior high school students were explored using interviews conducted before and after exposure to problem-solving software. A concept model of subjects' general beliefs about mathematics and their relationships was developed. Data analysis did not indicate any change in beliefs about mathematics following…

Proposes a teaching model to teach mathematics represented as a triad of three components: (1) management of learning; (2) mathematical challenge; and (3) sensitivity to students. Describes the three components and relates them to a constructivist perspective of learning. (MDH)

This paper reviews the present state, recent trends, and prospective lines of development concerning applied problem solving, modeling, and their respective applications. Four major trends are scrutinized with respect to curriculum inclusion: a widened spectrum of arguments, an increased universality, an increased consolidation, and an extended…

This article addresses the potential and the challenges of scaffolded instruction within the context of an exploratory study of the implementation of mediated collaborative problem solving. Implementation of the model for self-regulation with students experiencing reading difficulties is described, with suggestions for making scaffolded…

This paper describes how secondary teachers can use the Purdue Three-Stage Model as a framework for instruction that facilitates talent development in both heterogenous and homogenous classrooms. In the first two stages, students master the core content of a discipline and practice thinking creatively and critically about the content. In the third…

The recursive model presented here involves the study of drugs in the bloodstream and their subsequent elimination from the body. Both a basic and a more realistic model are presented and discussed in terms of an algebraic approach, a recursive approach, the graphical representation, and other extensions and connections particularly with models…

Student questioning within the Search, Solve, Create, and Share (SSCS) problem solving instructional model was investigated. The results suggest that the SSCS problem-solving instructional model increases student questioning in the presence of the teacher (n=22) when compared to a teacher-directed laboratory instructional model. The implications…

Describes the methodology for teaching cognitive self-direction (CSD) to preservice teachers, presenting an overview of the CSD model. The CSD curriculum model includes productive strategies such as modeling plus self-verbalization (goal-setting, guiding, and reinforcing behaviors). Benefits to preservice teacher education include improved lesson…
