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…

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)

The authors illustrate the magnitude and application of the concept of a "googol" (ten raised to the one hundred power) in searching for entities that exist in such number. (MN)

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)

Part one of a three part report on the historical development of curriculum guidelines for the instruction of chemistry in secondary schools. Part one covers the period 1893-1920. Parts two and three appear in November and December issues of School Science and Mathematics. (SL)

Presented is the 1921-1945 portion of a three part presentation outlining the effect of major committee reports upon secondary school chemistry teaching objectives during the period 1893-1975. (SL)

Methods for determining the radius of an atom are described. Unlike a previous article which approached the problem from an elementary perspective, this article examines a progression of increasingly sophisticated determinations. (CS)

Presented is the third part of a three part report describing the contributions of major committee reports to secondary teaching of chemistry during the period 1893-1975. This third part covers the period 1947-1975, and includes a brief summary of the entire three part series. (SL)
