The main purpose of this quantitative study was to examine the degree to which a three-week intervention in an urban high-needs high school science classroom would influence students' (n = 51) interest, utility value, content knowledge, and intentions for future study in chemistry. The intervention consisted of an authentic, inquiry-based…

Effective professional development that influences teachers' classroom practices starts with what teachers know, understand, and do in their classroom. The Next Generation Science Standards (NGSS) challenge teachers to make changes to their classroom; to help teachers make these changes, it is necessary to know what they are doing in their…

Chemical principles are taught in elementary education across much of the United States because the "National Science Education Standards" include concepts about the nature of matter, states of matter, and changes in matter among other science concepts within the first to fifth grade levels. "Chemicals" is a word related to the nature of matter…

The Information Technology in Science (ITS) Center for Teaching and Learning was a National Science Foundation funded program to provide high-quality professional development for 7-12th grade science teachers. The subgroup on which this paper focuses was immersed in an innovative approach to understanding chemistry of the environment. The group…

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…

This article investigates the effectiveness of improvising locally available materials for teaching chemistry in Nigeria, as a case for a culture of improvisation for teaching the sciences in developing countries. The scarcity and cost of imported materials for teaching science has remained a major challenge to teaching sciences in developing…

Science as inquiry is a key content standard #1 the National Science Education Standards; however, few secondary science teachers successfully and consistently implement inquiry-based instruction in their classrooms. This research examines the role of reform-based curricular materials in influencing the classroom practices of 12 high school…

Discusses a study that examined which reasoning patterns are necessary for success in high school chemistry. Based on student (N=170) scores from the "Classroom Test of Formal Reasoning," it was revealed that students who use formal reasoning patterns are capable of greater achievement in chemistry. (ML)

This article brings together the principles of designing Likert attitude scales and demonstrates the procedure through the development of a chemistry attitude scale. Design procedures and validity and reliability of the scale are each discussed, with a data summary for the 20-item chemistry scale. (MNS)

A study to investigate one of the mechanisms teachers may use to convince themselves incorrectly that students have learned science concepts requiring formal operational ability is presented. The investigation indicates instructors may actually teach and test for memorization of algorithms rather than understanding. (MP)

Chemical education in the People's Republic of China is examined by looking at a university entrance examination and the study guide used in preparation for this examination. (MK)

An integrated physical science course of approximately 40 instructional hours for eighth graders is described. The materials and text were prepared in accordance with the overall program for secondary school science drawn up by the Israeli Ministry of Education. (Author/MK)

A description is given of an Algebra II-Chemistry I combined high school class being taught in an attempt to coordinate chemistry topics with related mathematics topics. (MP)

Describes a reform effort for the undergraduate curriculum utilizing action-based research teams that developed, implemented, and assessed constructivist approaches to teaching undergraduate science content. Results indicate that the collaborative action-based research process was effective in contributing to the reform of undergraduate teaching.…

Discussed is the effectiveness of using analogies in chemistry instruction. Students' mathematics anxiety, spatial visualization skill, and proportional reasoning ability were found to be important aptitudes for determining chemistry achievement. The relationship between analogs and algorithms is described. (KR)
