Due to its abstract, theoretical nature, the mole concept has been recognized as one of the most difficult topics to teach and learn within the chemistry curriculum. The purpose of this study was to chronicle the development of high school students' conceptions of the mole following a period of instruction in a chemistry class. This investigation…

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…

The goals of this curriculum, developed as a summer course for the Young Scholars Program at The Ohio State University-Columbus, are as follows: (1) enable students to develop an understanding of the concept of a system; (2) help students gain an appreciation of the value of systems; (3) develop skills in working with systems; (4) expand skills in…

The Rural and Small Schools Conference has made a special effort to address the needs that pertain to science educators in rural and small schools. This publication presents the proceedings from the 1988 science education section of the conference. The content of the conference deals with a diversity of topics. The proceedings include a preface…

This paper discusses the relationship between the work that takes place in science laboratories and the science curriculum that is presented in the schools. The introduction asserts that although science education identifies itself with the scholarly disciplines of science, science educators should devise curricula that fairly represent these…

This book is composed of the following: materials used before and during a conference on evolution education, a proposed agenda for evolution education research, and related recommendations for evolution education research that arose from the conference. Abstracts of seven articles on evolution education, a literature review, and a section…

This study was designed to determine the number of states that are currently implementing Science-Technology-Society (STS) education and similar society-based, science education programs (STS-surrogates) in the United States and to describe the nature of this implementation. STS is operationally defined as the interaction between science,…

The Austin (Texas) Science and Mathematics Consortium funded by a 4-year grant that has 2 basic goals: to improve the skills of K-12 teachers in science and mathematics and to increase student learning and performance in science concepts. Program activities, which began in 1990-91, focus on four components: curriculum development, staff…

This curriculum unit provides students with real world applications of science as it pertains to toxic releases into the environment. This boxed package contains the Toxics Release Inventory (TRI) Teacher's Guide, TRI Database Basics guide, comprehensive TRI compact disk with user's guide, "Getting Started: A Guide to Bringing Environmental…

An approach to teaching problem-solving based on using the computer software Mathematica is applied to the study of electrostatics and is compared with the normal approach to the module. Learning outcomes for both approaches were not significantly different. The experimental course successfully addressed a number of misconceptions. Students in the…

The purpose of this study is to investigate the effects of two laboratory environments for introductory chemistry on undergraduate students' inquiry skills. The two laboratory environments are embedded in the same lecture course. The standard laboratory curriculum and instruction are distinct from the curriculum explored in this study, the MORE…

The world of education can be considered a natural laboratory in which different countries are experimenting with different strategies. This report presents the findings of the First and Second International Association for the Evaluation of Educational Achievement (IEA) Science Studies. The book contains the following chapters: (1) Issues in…

This book is designed to be a guide for a hands-on science experience for students in grades 3 through 6. Over 200 students can participate at the same time, moving from one station to another. The activities have been selected to encourage experimentation, creativity, higher-order thinking and fun with science. All activities use multi-modality…

National biology reforms often define evolution as the unifying concept in biology. However, few inservice teachers have an understanding of this role. The purpose of this study was to evaluate the effectiveness of a course sequence in evolution designed for inservice biology teachers on their conceptions of the role of evolution in biology.…

This newsletter issue focuses on the issue of recommended instructional and curriculum changes that are part of the current reforms in science education. The issue is composed of four articles. The first article, "Science Education: Schools Pushed To Broaden Access, Overhaul Practice," discusses the call for a science curriculum that…
