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 inquiry reported focuses on problems/difficulties of learning about the concept of "force" through…

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 primary, intermediate, and secondary students' (N=41) ideas about selected…

The purpose of this study was to introduce the Mole Solver, a computer based system that facilitates monitors and improves the students' problems solving skills on mole concept. The system has three distinct modes that: i) finds step by step solutions to the word problems on the mole concept ii) enable students' to solve word problems on their own…

"Concepts in Science" is the title given to a group of 17 related miniseries produced for senior science students. This report presents the results of the summative evaluation of this series. The series explored important concepts in three areas of study: biology; physics; and chemistry. Each series consists of six 10-minute animated…

A great number of misconceptions in diverse subject areas as well as across age levels have been documented and described. Photosynthesis is one of the more intensively studied areas in biology. The purpose of this research was to carefully select and define misconceptions about photosynthesis needing remedial efforts. To achieve this, a specially…

This practicum was designed to develop more positive attitudes toward science and to increase students' knowledge of science by providing supplemental hands-on activities. Second grade students were surveyed at the beginning of the school year and then were retested after participating in hands-on activities from 12 learning centers. The…

Comparing traditional to experiential instruction, a study investigated whether teaching content area vocabulary using hands-on experiences and teacher/student interaction would result in greater vocabulary knowledge and better comprehension of a related text than conventional dictionary work. Subjects, 45 fourth grade students from a chapter 1…

The first in a series of booklets on using outdoor education methodologies to enhance the academic curriculum, this guide is written to help teachers of grades K-8 develop activities to enrich science instruction. The introductory sections define outdoor education and provide a rationale for outdoor science teaching stressing the opportunities it…

In this paper examples of the role of analogical reasoning in expert problem solving are presented. These are intended to show that using an analogy can change an expert's understanding of a problem situation by changing the conceptual model he or she uses to think about the situation. This suggests that using a good analogy may allow students to…

In this study 34 spontaneous analogies produced by 16 college freshmen while solving qualitative physics problems are analyzed. A number of the analogies were invalid in the sense that they led to an incorrect answer from the physicist's point of view. However, many were valid, and a few were powerful in the sense that they seemed not only to help…

Observational techniques were employed to gain insights into students' experiences from three perspectives (learner, teacher, and observer) as related to four aspects of a set task (nature of the task, including its purpose; how the task was carried out; perceived significance of outcomes achieved; and significance of outcomes in terms of science…

This paper, designed to be used in conjunction with a video-tape developed by the Learning in Science Project (Primary)--LISP(P)--shows excerpts from some of the interview schedules used to examine children's ideas about floating and sinking. These interviews involved the use of "interview-about-instances" (IAI) cards (included in an…

This study investigated the meanings and ideas held and questions asked by children (ages 7-14) about floating and sinking (in water). Data were collected from interviews using "interview-about-instances" (IAI) cards (included in an appendix) and 10 objects which either floated or sank. Additional data were collected from classroom…

This report describes the results of an attempt to identify a learning hierarchy for each of a number of science concepts mainly encountered first in the high school grades. The concepts studied relate to stoichiometric calculations and molarity, both from chemistry; to food web relationships and problems involving Mendel's laws from biology; to…

Many words which have been treated in the denotative sense are actually connotative in nature. That is to say that citing a definition or stating a fact should not be a learning goal. Rather, a "conceptualization" should be what teachers are striving for. A series of activities dealing with density have been provided for demonstrations or…
