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…

Provides methods by which one may include historical aspects of the growth and development of chemistry into a secondary school curriculum. Includes a selected bibliography of materials related to the history of chemistry. (CP)

Reports data on 135 students completing the first year of the Nebraska Physical Science Project (NPSP). Those students who were most successful in this integrated and individualized course perceived themselve(PB)

Outlines an experimental procedure in which an iodine radioisotope is used to determine molar combining ratios of lead and silver with the iodine. Tables and graphs show the definitive results that should be attainable. (CP)

Evaluates the CHEM study topics of kinetic theory of gases, phase changes, chemical bonds, and equilibrium as to the level of cognitive development required for an understanding of each subject. Advocates an assignment of topics within the range of a student's cognitive ability in an individual study format of instruction. (CP)

Summarizes findings of 24 studies in which attempts were made to correlate achievement in college chemistry to many variables. A list of the most promising factors is provided. However, the author found no conclusive predictors in reviewing the research. (CP)

Mathematical solutions to simple atomic structure problems involving (a) simple cubic, (b) body-centered cubic, and (c) face-centered cubic models are presented. (CP)
