This paper reports the preliminary findings of a county-wide study of alcohol and other drug (AOD) behaviors and influences among 2,229 randomly selected students in grade 8, 10, and 12. The discussion focuses on behavioral, cognitive, and environmental predictors of AOD behaviors. The paper highlights a refined study of the influence of peers,…

Ten preservice biology teachers were followed through the final year of their preservice education to assess the content and stability of their knowledge structures of biology. A questionnaire asking the subjects to list the topics which make up biology and to diagram these topics in relation to one another was completed three times during the…

This paper presents background information about the development and functions of hypertext and predicts future changes in converting text into hypertext. The paper describes hypertext as a computer system that allows the interconnection of information in a way that is "transparent" (does not intrude on or interfere with the reader's…

The idea that breaks from experience are necessary and salutary in teacher education is a response to an enduring problem of teacher education: the fact that aspiring teachers come to their preparation with set ideas about teaching, learning, and schooling that fit with the larger ideal and institutional order into which they were born. Typically,…

This publication profiles nine secondary school teachers selected as the 1988-89 Laboratory Fellows by the Regional Laboratory for Educational Improvement of the Northeast and Islands. The Teacher Recognition Program is conducted by the Small Schools Network of the Laboratory to recognize outstanding teachers of a particular content area or skill.…

A study was conducted involving two experiments to address the question "What effects do students' beliefs about the nature of knowledge have on comprehension?" Experiment one involved 117 junior college students and 149 university students as subjects. An epistemological questionnaire was administered to the undergraduates. Factor…

This study explored the usefulness of an approach to science instruction which specifically considered children's spontaneous conceptions about natural phenomena. The aim of the instruction was the development of conceptual understanding. The instructional approach involved diagnosing children's spontaneous conceptions, making them aware of their…

This study describes the relationship of two cognitive variables, logical thinking and disembedding ability, to learners' abilities to make conceptual shifts from less acceptable to more acceptable conceptual understandings of a physical phenomenon. The difference in the logical thinking and disembedding ability of students who exhibited different…

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…
