The aim of this study was to investigate the effectiveness of a problem-based learning (PBL) approach in a physical chemistry laboratory course. The parameters investigated were students' attitudes towards a chemistry laboratory course, scientific process skills of students and their academic achievement. The design of the study was one group…

This research is part of a study on scaling-up middle school science curriculum units in a large, diverse public school system. Chemistry That Applies (CTA), a guided inquiry unit based on conceptual change theory and highly rated according to the Project 2061 Curriculum Analysis, was implemented in five middle schools matched demographically with…

Science, particularly the physical sciences, has undergone several paradigm shifts during history. The modernistic and mechanistic world that was viewed through the lens of Newton's laws no longer offers valid answers to present-day questions. This paper examines four themes: the evolution of physics, the evolution of chemistry, the evolution of…

Many chemists want to be effective teachers but have little background in psychology or education on which to build successful practices. The primary audience for this book is chemistry teachers at the secondary and tertiary levels, and its purpose is to encourage readers to construct a new understanding of how their students learn. This book is…

This book presents pioneering work in teaching by scientists, mathematicians, and engineers to attract and retain women in these areas. The physical sciences, mathematics, and engineering persist as the professional areas where women have not yet broken the gender barrier. A severe shortage of scientists beginning in the mid-1990s is predicted and…

This issue of "Indicator of the Month" lists percentages of high school graduates taking selected mathematics and science courses in high school in 1982, 1987, 1990, and 1992. Findings include: (1) High school graduates in 1992 were more likely to take mathematics courses at the level of algebra I or higher and most science courses at the level of…

This publication issues a challenge to students to collect data in a nationwide analysis of water hardness. Background information on the chemistry of hard water is presented using a cartoon format, and each of the four activities contains an explanation about the chemistry illustrated in the activity. The effect of hard water on soap, the effect…

Chemistry Quickies is not a textbook, but it can be used as a supplement to chemistry textbooks because it presents a questioning approach to critical thinking and critical reading. Since the book was arranged for daily sequence without dependence on topic grouping, students acquaint themselves with their textbooks through deliberate exploration…

This paper presents an approach to chemistry and nutrition that focuses on food items that people consider delicious. Information is organized according to three categories of food chemicals that provide energy to the human body: (1) fats and oils; (2) carbohydrates; and (3) proteins. Minerals, vitamins, and additives are also discussed along with…

This study examined the education of chemistry professionals in Brazil in light of the profile of such professionals in the current job market. Semi-structured interviews were conducted with 21 chemists employed by two foreign and one domestic companies in the state of Sao Paulo, Brazil. The chemists were graduates of the three major universities…

This report describes a methodology for increasing the validity and reliability of inferences made about the problem-solving ability of science students that is based on performance on different kinds of tests. The generalizable cognitive components of problem solving that might be targeted by assessment are described, and specifications are…

This report examines an attempt to use cooperative learning in two sections of a college chemistry course and focuses specifically on male and female student attitudes and achievement in the course. A total of 46 students participated. One lab section used cooperative structures throughout an entire 16-week semester while the other section used…

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…
