This paper describes a project undertaken as an interdisciplinary effort among four science departments, two disabilities services offices, and special education personnel to investigate the use and success of assistive technology devices as well as other equipment modifications in an attempt to transform science laboratories into environments…

The relationship between the multiple-choice and free-response sections of the Computer Science and Chemistry tests of the College Board's Advanced Placement program was studied. Confirmatory factor analysis showed that the free-response sections measure the same underlying proficiency as the multiple-choice sections for the most part. However,…

This study investigated perceptions of 56 students in 4 general chemistry labs regarding their understanding of chemical concepts and processes. Conceptual understanding of scientific investigation was the focus. Students using a pre-lab guide for lab preparation were compared with students completing a traditional pre-lab assignment. Data sources…

The purpose of this study was to investigate senior high school students' difficulties predicting the existence of hydrogen bridge bonds between organic molecules, investigate students' difficulties predicting the relative boiling points of simple organic compounds, and develop test questions that enable teachers to quickly get information about…

This curriculum and classroom activity guide considers evidence gathered in answer to questions concerning global environmental change. It describes methods that biologists, chemists, geologists, meteorologists, and physicists use to gather and interpret their findings. The activities and approaches in this guide were developed to meet the skill…

For various reasons, students do not have access to laboratory facilities and yet need courses in the laboratory sciences such as chemistry. This paper describes "Outreach Chemistry," a course developed to provide a chemistry laboratory experience for students attending schools that lack science laboratories. Designed for off-campus students whose…

Many students face chemistry courses with a sense of fear and foreboding because it is a required course. Yet at the same time, fundamentals of chemistry have become intertwined in countless professions to say nothing of its growing importance in our everyday lives. Educators must bridge this dichotomy between attitude and importance. This paper…

The main objective of this study is to construct models based on strategies students use to solve chemistry problems and to show that these models form sequences of progressive transitions similar to what Lakatos (1970) in the history of science refers to as progressive 'problemshifts' that increase the explanatory' heuristic power of the models.…

Among the 22 tests cited in this bibliography are end-of-course tests, tests of the American Chemical Society, and chemistry item banks. This document is one in a series of topical bibliographies from the Test Collection (TC) at the Educational Testing Service (ETS) containing descriptions of more than 18,000 tests and other measurement devices…

Vietnamese students now enrolled in American high schools incur an extremely special need in English. After being taught subject matter disciplines in Vietnamese for many years, and while English is still a foreign language for them, these students are bound to go through two linguistic processes. First, while reading or sitting through lectures…

This article discusses ways in which secondary polytechnical schools in Russia can acquaint pupils with the basic ideas of applied chemistry. Students must be guided so that they can choose a vocation in accordance with their personal inclinations and the needs of society. (Author/RM)

Describes the use of disc or ring magnets magetized axially and iron discs, in conjunction with an overhead projector, as a model of nuclear structure and of complete molecules. (GS)

Describes the findings of a questionnaire, completed by a sample of chemistry teachers in England, concerning inservice needs. Statistical analyses are provided for the differences in opinion about reasons for taking inservice courses and what course contents were preferred. (MLH)

Describes secondary and higher chemical education in Canada, including credit hour requirements, types of curricula used, and administrative details. The control of education is considered the right of each of the 10 provinces while science policy and the funding of research is largely controlled by the federal government. (MLH)
