Describes activities to help students understand pH scales and acid rain. (PR)

Describes a three-week environmental minicourse in a general chemistry class. The minicourse consisted of two distinct phases, a one-week introduction to environmental chemistry and a two-week project involving a particular environmental problem. (PR)

Describes a demonstration of the principles of a voltaic cell using lemon cells to power a calculator and other items. A lemon fortified with a penny and a galvanized nail produces a potential of one volt. (PVD)

Discusses leadership issues that arose during the creation and offering of an Internet-based course for high school chemistry teachers including course organization, recruiting students, and technological support available to participating students. (Author/WRM)

Describes a senior-level capstone experience that integrates various communication and research skills to prepare chemistry majors for entry into graduate school and professional life. Contains 12 references. (WRM)

Students (N=379) in the 8th grade of German college preparatory schools, prior to formal chemistry instruction, were evaluated for prior knowledge of chemistry, their self-concept regarding chemistry, their gender-bound attitudes toward chemistry, and their fear of chemistry. Findings indicated that girls already expressed significantly lower…

Examined preservice teachers' concerns about transforming their academic knowledge into teaching activities (pedagogical content concerns). Prospective chemistry teachers individually prepared high school chemistry lessons. During group meetings, they presented and discussed the lesson plans. Data from interviews during individual and group…

Describes prospective teachers' conceptions of what one needs to know to be a chemistry teacher at the German gymnasium, and compares their conceptions with those emphasized by the university they attend. Hypothesizes that preservice teachers' conceptions suggest a nested model of knowledge needed for chemistry teaching. (Contains 30 references.)…

The aim of this study is to investigate and compare level of understanding of eighth-grade students and student teachers in their final year in the science education department related to concepts of solution, gas, and chemical change. A qualitative and quantitative methodology was used for this investigation. Open-ended questions and group…

This study investigates the proximal and distal images of the nature of science (NOS) that A-level students develop from their participation in chemistry laboratory work. We also explored the nature of the interactions among the students' proximal and distal images of the NOS and students' participation in laboratory work. Students' views of the…

Using the US national sample from the 1995 Third International Mathematics and Science Study (TIMSS), this study examined students' competence levels in understanding the matter concept at grades 3, 4, 7, 8 and high school graduation, and compared them to the expectations in the US national science education standards. It was found that…

Teaching philosophy should be based on the desired outcome of the teaching. In the case of science education, the guiding principle for a teaching philosophy should start with the desire to help students understand and use science, regardless of their major or profession. To effectively teach students how to understand science, one must include…

The purpose of this study was to investigate the effectiveness of small group discussion on students' conceptual understanding of chemical equilibrium. Students' understanding of chemical equilibrium concepts was measured using the Misconception Identification Test. The test consisted of 30 items and administered as pre-posttests to a total of 81…

This project presents a model for the development of an innovative, highly-experimental teaching laboratory course that centers upon collaborative efforts between recent alumni currently enrolled in Ph. D. programs (consultants) and current faculty. Because these consultants are involved in cutting-edge research, their combined talents represent a…

The average age of students at Lake Michigan College (LMC) is twenty-eight years old. In the current study, the application of customized internet assessment for Chemistry 101, Introductory College Chemistry, from 2001 to 2005 is compared with traditional assessment from 1996 to 2000. The authors describe the ways in which computerized assessment…
