Many researchers have investigated the effects of students' prior knowledge upon learning chemistry, for example, the tenacity of alternative conceptions. Knowledge about learning also shapes students' learning of chemistry. This research describes the development of CHEMX, a survey instrument that measures an aspect of knowledge about learning…

This book is a result of a workshop where 14 science educators were invited to draft chapters on the implications that the research studies in a specific content area of science have for its teaching. The relations between social forces and perceptions of purpose and content lay behind discussions in the workshop, and influenced the emergence of…

A study was conducted at Prince George's Community College, in Maryland, to investigate the relatively low pass rates associated with General Chemistry 1 (CHM101), a lower-level science course that satisfies a general education requirement and serves as a prerequisite for Chemistry and Biology students. To identify correlates of student success,…

This book highlights the importance of science and technology education in Australia in the post-compulsory years. It outlines the themes of how and why science and technology are now being so regularly associated in reports and reviews of education and training and contains an account of the changes in the societal and educational contexts that…

It has been found that when examinees are allowed to choose a subset of constructed response (CR) items to answer on a test, they tend to choose differently and often perform lower on more popularly chosen items. The purpose of this study was to examine this finding. Using an experiment that incorporated a revised Advanced Placement (AP) Chemistry…

ChemSource is designed as a strategy to help preservice and inservice high school chemistry teachers promote student learning more effectively. Its major premise is that well-designed laboratory investigations are an important avenue for cultivating student interest, engagement, and meaningful learning in chemistry. The SourceBook component of…

This paper summarizes a pair of studies titled "The Impact of Longer Term Intervention on Reforming the Approaches to Instruction in Chemistry by Urban Teachers of Physical and Life Sciences at the Secondary School Level" (William J. Priestley, Holly D. Priestley, and Joseph S. Schuckler) and "Profile of Instructional Practices…

This series of educational activities is intended to help teachers communicate basic scientific concepts related to global warming and the greenhouse effect to students grades 7-10. Seven sessions provide laboratory activities, simulations, and discussions that can be used to improve student understanding of a number of important scientific…

This study examined the relative effect of a HyperCard based approach to solving stoichiometric equations using Hyperequation, and traditional pen-paper methods on the performance of expert and novice high school chemistry students. Hyperequation is programmed to register student responses, provide immediate feedback, and keep a record of all the…

The Inventory of Innovative Learning Materials in Marine Science and Technology includes 32 computer-, 148 video-, 16 film-, and 11 CD-ROM-based entries. They concern materials in biosciences (67), chemistry (5), geosciences (16), physics (23), technology (76) and other (20). This first, initial compilations is conceived as the basis for more…

This report sets out results for Australia arising from its participation in the Second International Science Study (SISS). The focus is on Year 12 students, including those studying science and those not currently studying science. Most of the results for the science students are presented separately for those specializing in biology, chemistry,…

This paper explores a teacher's perspective of what successful science instruction is and how these perspectives influence classroom instruction. The data sources for this study include 35 classroom observations and approximately 25 hours of interviews collected over a period of 2 years of a single high school chemistry teacher. During class,…

The predictive and incremental validity of both the Old and New Medical College Admission Test (MCAT) was examined and compared with a sample of over 300 medical students. Results of zero order and incremental validity coefficients, as well as prediction models resulting from all possible subsets regression analyses using Mallow's Cp criterion,…

Several central ideas emerging from a systematic approach to teaching problem-solving in the quantitative sciences (chemistry, physics, engineering) are discussed. Areas addressed include: differences between teaching and performance, between naturalistic and effective functioning, and between detailed observations and gross statistical data;…

The hypothesis as to the atomic structure of any given substance is introduced in many physics and chemistry textbooks by conveying the idea of repetitive division of a given amount of substance, for example, by grinding, dissolving, or evaporating. The rationale for this approach is the assumption of students inferring that this process of…
