This paper puts forth techniques for the promotion of reflection which can be used in university seminars for preservice teachers. The techniques are based on the idea of reframing, i.e., looking at experiences from a new perspective. From a cognitive psychological point of view, this means that the person's cognitions about a situation or…

Critical review of previous techniques for the measurement of an individual's self-concept (SC) is a necessary prelude to the development of more adequate methodologies. This paper focuses on recent methodological innovations in the study of the self, namely, those derived from cognitive social psychology. A view of the self as a cognitive…

In two studies, the role of biomedical knowledge in the diagnosis of clinical cases by physicians and medical students was explored. Experiment 1 demonstrated a decrease in the use of biomedical knowledge with increasing expertise. This result appeared to be at variance with some findings reported in some but not all of the literature. In…

In a step toward creating a robust natural language understanding system which detects and avoids miscommunication, this artificial intelligence research report provides a taxonomy of miscommunication problems that arise in expert-apprentice dialogues (including misunderstandings, wrong communication, and bad analogies), and proposes a flexible…

The pamphlet reviews cognitive and developmental psychology research in which skilled and less skilled performance patterns and mechanisms have been compared. Knowledge has been described, in theory, in terms of an associative network in which concepts are represented as the nodes of the net, and relations between concepts serve as associative…

This paper explores a wide range of issues associated with research on mental models. Based on a functional perspective, mental models are defined as the mechanisms whereby humans generate descriptions of system purpose and form, explanations of system functioning and observed system states, and predictions of future system states. Specifically,…

Some science educators who are interested in conceptual development have considered the phenomenon of student misconceptions and alternative frameworks. Researchers have used a variety of terms to describe the situation in which students' ideas differ from those of a scientist about a particular concept. This digest was produced to briefly…

This newsletter describes an ongoing empirical field study involving a description and analysis of practical teaching situations aimed at describing the content and structure of pupils' frames of reference. The project takes the form of a series of case studies in classes of the 3-year lines of upper secondary schools in Sweden. The study seeks to…

Without special training, most people predominantly process data in one of four ways. Few achieve a coveted whole brain state that integrates such important but separate brain functions as logic and intuition. With new training techniques that exploit the holographic properties of the brain, organizations may be able to tap powerful whole brain…

This study investigated the flexibility of 16 supervisors in implementing a developmental approach to supervisor-supervisee interaction during the postobservation conference. Specific objectives included determining: (1) if supervisors' diagnoses of supervisees' conceptual levels (CL) agreed with the Paragraph Completion Method (PCM) measurement…

The reviews of articles contained in this issue have been grouped into those dealing with research related to cognitive development and to instruction. In addition, seven science education researchers have provided responses to critiques of their published research. Included are: (1) an analysis of an article designed to persuade researchers to…

This paper examines how teachers develop and modify professional knowledge in response to experience and to new research knowledge. A discussion is presented on the interaction of propositional knowledge (the basic medium of classroom and research knowledge) and practical knowledge (the observable competence apparent in successful professional…

The purpose of this paper is to make educators, authors, and publishers aware that they must be concerned with rhetorical form as well as content if they wish to present students with accessible, useful textbooks. Using a case study of textbook perception and use in a school district's sixth grade social studies classrooms, the paper illustrates…

Secondary school geometry students have been found to have misconceptions concerning parallel lines. Correctional teaching programs did not seem effective in changing these misconceptions. This research describes an attempt to use teaching strategies which take into account current learning theory and which encourages students to be actively…

This paper describes further research on a learning procedure for layered networks of deterministic, neuron-like units, described by Rumelhart et al. The units, the way they are connected, the learning procedure, and the extension to iterative networks are presented. In one experiment, a network learns a set of filters, enabling it to discriminate…
