Criticizes weaknesses in the Gagne research model for checking the validity of learning hierarchies, and proposes a new model which is designed to overcome these weaknesses. (JR)

Describes a heuristic model that facilitates the conceptualization of linguistic-imaginal processes and forms the basis for a method of relating learner aptitudes to specific instructional stimuli in science education. (MLH)

Kindergarten children who had been given cues during instructional sessions on serial ordering performed significantly better on serial ordering posttests than did the control group (no instructional sessions). Author concludes that the acquisition of serial ordering capabilities depends in part on learning and not solely on the development of…

Points out the fact that Piaget's objections to tests as ways of identifying cognitive structures and processes have been largely ignored in most of the replication studies conducted by English and American psychologists. (PEB)

The paper focuses on problems science educators and researchers must face before the advantage of paradigms can be realized. Examples of the role of paradigms in physics research are presented. A critique of paradigm use in physics is presented. Future variations of paradigms for science education are discussed. (Author/RE)

This paper examines how some fundamental mechanisms of nervous system activity can explain human information processing and the acquisition of knowledge and provides additional theoretical support for constructivist applications to science education reform. The implications for scientific epistemology and conceptual change processes in science…

Examines the individual and cumulative effects on achievement of providing students with objectives, sample test items, and a mastery strategy that included diagnostic testing and remedial instruction. Also investigates the effects of mastery learning on achievement of students with different aptitudes for learning. (Author/GA)

Presents a progress report on some methodological advances made on certain facets of the problem of the learning of a structure of a subject matter. (PEB)

Comments on the study reported by Lawson, Karplus, and Adi (1978) which indicated that formal schemata and propositional logic are not part of the same structured unity of mental operations proposed by Piaget. (HM)

Presented is a paradigm for science education research. The paradigm advances the reception learning theory, where regularities to be learned are presented explicitly to the learner. A tool for the study of knowledge production in science education, the Gowin "V," is presented. (RE)

This report describes an attempt to apply a critical empirical test to some predictions from Ausubel's theory concerning the subsuming role of advance organizers. Alternative explanations are proposed and subsequent predictions tested. (BT)

Investigates the effects of teaching 120 first grade children specific strategies for nonvisual seriation on their performance on post-tests and retention tests. Results show that simple seriation can be learned and retained. (HM)

Investigates whether an environmental program including an advance organizer component and a field experience results in an observable change in the environmental orientations of fifth- and sixth-grade students. Results show positive change. (HM)
