The supplantation approach of this study hypothesized that media attributes may serve to bridge the processing link between learner aptitude capacity and the demands of a concept attainment task. Subjects were 492 males aged 16-21, drawn from a College of Technical and Further Education in Melbourne, Australia. All subjects were trade apprentices,…

This paper reports on an experiment designed to determine whether a novice second-language (L2) reader can be characterized as concept-oriented or syntactic-structure oriented. The operating premise was that high school L2 students read and understand not so much by translating as by combining conceptual fragments into a tentative "script," which…

The high percentage of students who have difficulty in solving free-response problems related to the mole concept was addressed by implementation of reading skill strategies and computer assisted instruction. Frayer models, semantic mapping, and graphic organizers from Reading in the Content Area (RICA) were used to increase student understanding…

Three socioeconomic classes of rural students ages 6 to 18 were interviewed about their conceptions of the rich and poor and economic inequality. The 114 students in the sample were divided as follows: (1) middle class, 23; (2) working class, 61; and (3) lower class, 30. Responses of the students are analyzed according to Leahy's categories of…

Deciding how to approach a word problem for solution is a critical stage of problem solving, and is the stage which frequently presents considerable difficulty for novices. Do novices use the same information that experts do in deciding that two problems would be solved similarly? This set of four studies indicates that novices rely more on…

This book contains 15 chapters: (1) "Teaching Problem Solving"; (2) "Using Calculators and Computers in Elementary School Mathematics"; (3) "Organizing for Instruction"; (4) "Teaching Numeration of Whole Numbers"; (5) "Teaching Numeration of Common and Decimal Fractions"; (6) "Teaching Addition and Subtraction of Whole Numbers"; (7) "Teaching…

Students of reasoning have long tried to understand how people revise systems of beliefs. This paper maintains that people often change their beliefs in ways driven by considerations of explanatory coherence. In this report, a computational model is described of how experimental subjects revise their naive beliefs about physical motion. First,…

Intended for curriculum developers, this revised Framework presents a set of basic concepts for teaching K-12 economics. The revision reflects the change and development which the field of economics has undergone and includes improvements suggested by users of the first edition. The purpose of teaching economics is to impart a general…

The Project OMNI curriculum is intended to help students develop necessary prerequisite skills for independent travel. The teacher's guidebook provides an overview of the OMNI curriculum components (individual student inventories, individual student profiles, and curriculum modules); discusses the relation of the module areas to the mobility…

One area explored in the second (in-depth) phase of the Learning in Science Project was "children's science," defined as views of the world and the meanings for words that children have and bring with them to science lessons. The investigation reported focuses on the concept of "electric current" held by 43 elementary school…

This paper proposes some possible areas of research and tentative theoretical guidelines for the Learning in Science Project (Primary)-- LISP(P). This new project, designed to investigate the teaching and learning of science in the primary school, arises from the work of the original Learning in Science Project (LISP). LISP(P) has two…

This study investigated the development of teachers' conceptions of learning disabilities (LD) as a function of experience with pupils having LD. An expert group of 25 LD-certified special education teachers, a transition group of 24 regular classroom teachers of mainstreamed LD pupils, and a novice group of 20 undergraduate special education…

At a time when many public school teachers and administrators are limiting instructional goals to the lower level objectives found on standardized tests, there is a need for classroom activities derived from higher purposes. Conceptual analysis, which relates abstract concepts to the lives of students, meets this need. While focusing primarily on…

An outline of the knowledge and skills to be taught in a high school world regions course in order to meet the Department of Defense Dependents Schools (DoDDS) social studies objectives is provided. Material is divided into three parts. Following an introduction, a one page description overviews the curriculum topic for high school world regions,…

Advances in cognitive science have greatly increased our knowledge of how the human mind stores and uses information. That knowledge can be used to decompose curricular objectives so as to increase the specificity of instruction to a level of precision that should greatly enhance student writing. This article identifies some major types of…
