This research examined the effects of belief-based messages on the intentions of ninth and tenth grade, Hispanic-American students to enroll in their first elective science course at the pre-college level, chemistry. The design of the study was guided by the theory of planned behavior (Ajzen, 1989) and the Elaboration Likelihood Model of…

The relationships of science anxiety to measures of achievement, test anxiety, year of chemistry taken, and gender were investigated for high school students; the study also attemped to establish reliability data on the Czerniak Assessment of Science Anxiety (CASA) of L. Chiarelott and C. Czerniak (1987). Subjects were 101 students (45 males and…

The main purposes of this study were to investigate the relationships among approaches to studying, prior knowledge, logical thinking ability, attitude, and performance in college freshman chemistry and to explore the effect of gender on the same variables. Subjects were 199 students (114 females, 85 males) enrolled in the second semester of a…

Faculty members in departments of chemistry, computer science, and education were surveyed to collect information on the content representativeness of the Graduate Record Examination (GRE) Advanced Tests in those disciplines. Faculty respondents allocated percentages to each of the major content categories of the specifications for the tests to…

The Zimbabwe Secondary School Science Project (ZIM-SCI) developed student study guides, corresponding teaching guides, and science kits for a low-cost science course which could be taught during the first 2 years of secondary school without the aid of qualified teachers and conventional laboratories. This ZIM-SCI study guide is a two-part unit…

Findings generated from past classroom observation and individual interviews indicate that certain framework conceptions can be identified by which students explain special transformations of substances and which are activated in view of new experiences made in the course of chemistry instruction. This study investigated these framework…

This article describes steps taken to demystify the writing of chemistry as part of the development of a junior level writing course for chemistry majors at Northern Arizona University (NAU). Although the course is offered by the chemistry department, its conception, development, implementation, and assessment have been the result of an…

Since their introduction into schools, educators have tried to utilize computers in classes in order to make difficult topics more comprehensible. Chemistry educators, when faced with the task of teaching a topic that cannot be taught through experiments in a laboratory, resort to computers to help students visualize difficult concepts and…

Chemistry 30 is a 12th-grade science course for students in Alberta, Canada. This document is the final test for the course. Intended for administration during June 1989, it contains 56 multiple-choice questions and 3 written-response questions. Two-and-one-half hours are allowed for completing the test. No answer key is included since scoring is…

Too often science seems to be a matter of studying from books and responding to questions raised by teachers about the information either in the classroom or on examinations. Such a view of science misses its importance as a way of thinking, doing, and preparing for citizenship roles. The problems and activities included in this volume are…

Discussed are: (1) "Rain"; (2) "Water Cycle"; (3) "Fossil Fuels"; (4) "Air Pollution"; (5) "Superstacks"; (6) "Acid/Neutral/Bases"; (7) "pH Scale"; (8) "Acid Rain"; (9)…

The North Carolina End-of-Course Testing Program was established to provide student, school, and school system information about achievement in high school courses. This report describes: (1) "Characteristics of Chemistry Students"; (2) "Student Performance on the Core Test"; (3) "Combining Performance and Participation:…

An investigation of Ontario high school students' understanding of acids and bases with quantitative and qualitative methods revealed misconceptions. A concept map, based on the objectives of the Chemistry Curriculum Guideline, generated multiple-choice items and interview questions. The multiple-choice test was administered to 34 grade 12…

This resource guide provides information for 13 laboratory experiments designed to be conducted in small schools with limited equipment and materials. For each experiment, the document outlines necessary equipment and materials, experiment procedures, and questions to be answered. The experiments are: (1) studying the properties of water; (2)…
