The main objective of the study was to determine Pre-service Chemistry Teachers' (PCTs) understanding of isomerism related concepts of Aliphatic Hydrocarbons (AHs). To get in-depth picture of PCTs understanding on isomerism related concepts of AHs, case study was employed. The sample for this study consisted of twelve participants selected from 87…

Textbooks are an important source of knowledge input on which the transmission of academic knowledge often relies, especially in the early stages of academic learning. Adopting a corpus-based approach, this study evaluates the text difficulty of science textbooks used in secondary English-medium instruction schools in Hong Kong, with a focus on…

This research considered students' abilities to read images about dispersed systems, taken from the chemistry textbook. 103 high school students (37 males, 63 females, and 3 unknown) from the school "Svetozar Markovic" in Novi Sad, Republic of Serbia, were included as the research participants. Students' abilities to suggest the titles…

The importance of kinetic metastability is illustrated in detail using several common household products and recommendations are made for how this important and widespread, but often neglected, phenomenon can be more effectively presented in the introductory chemistry textbook.

Identified are errors in diagrams from the textbook "Physics" (Little, Brown, and Co., Boston, 1987). Presents and discusses the errors in eight textbook diagrams. The errors include mechanics, optics, and electricity. (YP)

Ways in which the concept of oxidation-reduction has been treated in the current popular textbooks of general college chemistry are discussed. (HM)

Replies are given to students' complaints about their physics textbook, "PHYSICS, Principles and Problems" (Merrill, Bell & Howell). Indicates wrong answers to some of the problems in the book. Discusses several topics identified by the students. (YP)

Examines the possibility that part of the problem in the teaching of physical science may lie in teaching-learning materials. Selects 14 chemistry textbooks and 14 physics textbooks in Australia. Analyzes them based on learning theory and scientific literacy. (YP)

Discusses some incorrect representations of electric fields in textbooks. Considers total charge or charge density and two- or three-dimensional diagrams. (YP)

Described are features of a theoretical model for fluid pressure. Analyzes six introductory physics textbooks based on an introduction and meaning of the pressure concept; characteristics of pressure; and liquid as a pressure transmitter. Presents three models of pupils' conceptions. (YP)

Indicates and describes items that are incorrect in textbooks and a teacher edition of Discover SCIENCE for K-6. (YP)

Reports on a symposium on reforming general chemistry curriculum sponsored by American Chemical Society's Education Division. Presents several discussions including levels of the goals of general chemistry, newly recommended content, and the pros and cons of descriptive chemistry. (YP)

Reviews the problem of certain logical and conceptual shortcomings in textbook presentations of the energy concepts in introductory physics. Discusses concepts and principles related to thermodynamics and echanics. Provides many formulas and diagrams. (YP)

This study, conducted in an Australian institution, investigates the intellectual requirements of the mechanics section of a first-year college physics text. Instructional and prerequisite concepts were classified in terms of the intellectual skills required to understand them. (HM)
