These include a short summary of research activities; research methodology;outline of a theory and summary of supporting evidence related to conceptual barriers encountered in teaching science to adults; students' views on critical barriers; a taxonomy of critical barriers(focusing on pervasive barriers, barriers recognized in narrower contexts, and barriers related to mathematics); problems with mathematics; ecological contexts of critical barriers (psychological sources of learning problems, differences in personal learning styles, and problems with pedagogenic causes); clues from science history (biographical/historical sources of critical barriers); description of a college level "Man and Nature-Energy" course, including list of difficulties students encountered; and notes and reflections on the course by a participant/observer. A list of references, annotated list of relevant psychological literature, and the proposal submitted to the National Science Foundation (NSF) are included. The NSF proposal provides the rationale/background for and significance of the research. The document is associated with five additional volumes of detailed records. Contents of these volumes are included at the beginning of this document, (Author/JN) ********************x************************************************** Reproductions supplied by EDRS are the best that can be made from the original document. *******************k*************************************************** U S.

In these essays we have undertaken to abstract, analyze, and give theoretical formulation to material contained in the record (and, of course, in personal notes and memories). The record,is one of teaching sessions in two types of courses, one for undeTgraduates and one for elementary school teachers, inservice; it is also a record of teachers' commentaries and of our staff discussions along the way, plus other material which seemed appropriate to include (Table-of Contehts, below). In our original proposal (Appendix B) wg asked for financial support over a three year period. As finally granted our support from the National Science Foundation was for half of that period, with theinjunction that we were to demonstrate the feasibility of theprocedures we had proposed to use. In the matter of time we have found sufficient non-NSFfunding so that we could continue our work for an extra semester, and augmenting our staff for the last year by one half-time researcher. Our major activities, as mentioned above, have been tgo intensive teaching-observing commitments. One of these was to co-teach and observe an undergraduate course, Man and Energy, inthe Fall of 1980 and again in the Spring of 1981. The description of this course is contained in RonCOlton's paper on the Energy course (pp. 1) and MajaApelman's papet (pp. I) and a commentary on it in the essay,Notes and' Reflections on Course by Maja Apelman. Dr. Apelman, a long-time member of thestaff of the Mountain View Center, experienced as a teacher of young childrer and as aprofessional\ advisor to elementary school teachers, describesherself as scientifically 3 - difficulties in science which areoften on naive, encountering conceptual students she is observing.

This major commitment of time wasvaluable to us in several ways, such a explicated in the essaysmentioned above.

A detailed record almost all of five volumes (see Contentsbelow). This record includes It excludes periods when wewere our little lecturesand discussions. t 4 in small groups for lab work, and a few other occasions. On these occasions we kept individual notes not reproduced here. The teaChers in these two courses (about 10 in each group) were selected on the basis of their responses to descriptions which we circulated. Several of them were already well known to us from their previous association with the Mountain View Centcr, and known as able and serious professional teachers. They could also be described, mainly, as scientifically naive, for the most part laaing even the rudiments of modern understanding in the physical and natural sciences. Finally, and most importantly, these teachers came forward with some understanding of our purpose.This purpose was the dual one of helping them learn more elementary science, relevant,, to their own teaching, and of enlisting their help in describing and accounting for the conceptual difficulties they had already'experienced ip learning science, or would experience under our tutelage. The topics for the first semester were Size and Scale, ahd Heat and Temperature. For the second semester the sole topic was Light and Color. The essays included in this volume are diverse in style and viewpoint. This diversity reflects the stage to which our research has advanced, a stage at which there is an embarassment of riches, a record containing far more than we have been willing, or able, to use. For such data as can be extracted from our five volumes of record there is no easy summary possible, and for most readers our samplings from them, in these essays, must be taken on faith. The original volumes are course available for scrutiny by anyone sufficiently interested. Parts of them would prove fascinating reading, while other parts (poorly transcribed, for example) would prove almost unintelligible to one not cued in by personal memory.
