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)

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)

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)

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)

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)

Investigated is the value of preliminary high school experiences in physics and chemistry. Results indicate that the grades of students with more high school experience are no better than those of students with less experience and that less experienced students spend more time studying and take better advantage of tutors. (CW)

Evaluated and compared 12 science textbooks with respect to their readability levels and agreement with the intended reader level. Four of the books were determined to be unsatisfactory for their intended grade levels. (20 references) (MDH)
