The primary goal of this project is to assess the students' better communication attainment after applying a series of five interactive strategies to an experiment group of subjects. This class will be compared with a control group of other participants, and in their class, the interactive approaches are not emphasized and practiced openly. The…

Transitioning to and from post-compulsory education often poses problems on students, especially students with disabilities. The fourth Ed-ICT symposium at the FernUniversität in Hagen aimed at discussing new practices, identifying problems and challenges during transition processes, and developing innovative solutions for both individuals and…

We taught a group of experienced in-service primary school mathematics teachers the notion of mathematical model, in order to foster the interdisciplinary mathematics teaching in primary school. In particular, we developed an exercise in which they were supposed to construct a mathematical model on the basis of primary school mathematics. We found…

The model of the six mirrors of the classroom and its use in teaching biology in a cooperative learning mode were implemented in high school classrooms. In this study we present: a) The model of the six mirrors of the classroom (MSMC). b) Cooperative learning settings: 1. The Group Investigation; 2. The Jigsaw Method; and 3. Peer Tutoring in Small…

Presents an instructional strategy based on the thesis that science concept learning involves cognitive accommodation of an initially held framework. The three stages of the strategy--exposing alternative frameworks, creating conceptual conflict, and encouraging cognitive accommodation--are illustrated in two lessons on the particle model of…

The purpose of this study was to determine how children at different ages understand the concept of temperature, examining particularly the logicomathematical aspects of the concept. In doing so, three developmental approaches were compared: (1) Piaget's structuralist approach; (2) Siegler's rule assessment approach; and (3) Anderson and…

In science teaching insufficient emphasis is placed on the fact that models are simulations of reality based on a certain theory and that molecules are not miniatures of the models that represent them. The study reported in this paper investigated how chemistry teachers perceive the nature and functions of models. The research population included…

Sixty-nine Israeli school principals completed questionnaires designed to reveal the factors contributing to the leadership styles they used when initiating curricular changes. The principals fell into three leadership categories: "Initiators," who seek change in accordance with long range policies and goals; "Responders," who…

In this research we examined and assessed the impact of implementation of a model using authentic investigative activities for teaching ratio and proportion in pre-service teacher education. The model was developed following pilot studies investigating the change in mathematical and pedagogical knowledge of pre- and inservice mathematics teachers…

Proof by mathematical induction is known to be conceptually difficult for high school students. This paper presents results from interviews with six experienced high school teachers, concerning the use of models in teaching mathematical induction. Along with creative and adequate use of models, we found explanations, models and examples that…

It has previously been shown by M. Beller (1990) that an additive tree (Addtree, a hierarchical tree representation of similarity data developed by S. Sattath and A. Tversky in 1977), may be useful for representing the structure between tests and items through the similarity among them as measured by their intercorrelations. In this study, the…

This paper, designed to assess the degree of implementation of the important features of a curriculum innovation, was presented at the 1978 Bat-Sheva Seminar on Curriculum Implementation and its Relationship to Curriculum Development in Science, Rehovot-Jerusalem, Israel. It investigates the use of sub-interviews within the main interview to…

The computer-mediated communication (CMC) learning environment focuses on children's interaction with the computers and their mastery of the technology as potential for learning. Peer interaction mainly in cooperative and collaborative learning environments (CL) focus on the contribution of peers to literacy and writing development. A study…

This is an initial examination of findings from laboratory and field studies done in Israel on the cognition-cultivating functions of media. The studies reasoned that highly explicit presentations of film-mediated operations can be imitated by observers, and that once imitated, they are internalized and can serve as modified mental skills. Two…

This paper presents a rationale and a conceptual framework for a wider research project dealing with mathematical communication, and in particular with actions performed by interlocutors whenever they wish to clarify their use of a symbol, a word or an expression. The aim of such actions is often to repair a communicational breach resulting from…
