Cognitive Acceleration through Science Education (CASE) is an innovative teaching approach born out of research into cognitive development based largely on the work of Piaget, and also incorporating fundamental tenets of Vygotsky's theories of learning. The program aims to improve children's thinking processes by accelerating progress towards…

This study investigates the ideas and beliefs of a small group of high school science teachers about student observations in the science classroom. Student views on science classroom observations have been previously reported on, but teachers and their students' ideas about observation is a very little researched area in science education. There…

This digest discusses block scheduling and it relates to teaching standards, staff development standards, and assessment standards. The standards are examined in terms of how they can be achieved through the use of block scheduling, and conclusions stress the necessity of scheduling for maximum student learning. (DDR)

Considers the development of science curricula from World War II and how the emphasis has changed to conceptualization of science knowledge in order to encourage intellectual activity. As well, this change has led to an improved climate for curriculum innovation. (Author/RK)

Rationale, objectives, and instructional strategies for a directed study course on spectrophotometry are provided. Descriptions of three experiments and four student research projects are also provided. Objectives, laboratory procedures, advantages, and disadvantages for the experiments and projects are included. (JN)

Describes characteristics of and instructional strategies related to an applied physics course offered by the New South Wales Institute of Technology in Sydney. The course has a number of unique features which enable its students to be of immediate use to industry upon graduation. (JN)

A course was developed to teach physics concepts and to help students understand mathematics, the nature and role of engineers and engineering in society, and to distinguish between science/technology from pseudo-science. Includes course goals/content, mechanics, start-up, and long-term projects. (JN)

Describes field course which emphasizes mapping techniques and preparation of a field report. Includes course methods/procedures, course schedule (broken down by weeks), grading practices/methods, student response to and performance in the course, nature of field area studied, and comments to those who may want to adapt such a course. (JN)

Explains cognitive basis for change in science paradigms using Watson-Crick DNA model to illustrate concepts of "normal" versus "revolutionary" science. Examines these concepts in light of teacher preception of science, and discusses implications for the practice of science education. (JM)

Summarizes results of the meta-analysis of 105 research studies dealing with effects of new science curricula on student performance. Twenty-seven different new science curricula involving one or more measures of student performance were included in the analysis. Positive performance patterns were found in all new curricula examined. (JN)

Study aids have been developed in a format allowing students to assimilate partial answers slowly, without consulting the whole answer. Discusses rationale and advantages of using the aids and provides three examples demonstrating logical thinking required to solve short-answer problem and use in multistep mechanistic or synthetic problems.…

Coping with the high cost of teaching chemistry, content of organic chemistry, instructional strategies, and approaches in dealing with the changing student population (urban blacks/hispanics, handicapped, and other nontraditional students) are among the topics discussed in 19 papers presented at the Seventh Biennial Conference on Chemical…

A two-part unit for second-grade students was developed to make children aware of the kinds of energy, problems connected with each energy type, and to introduce the decision-making process. Rationale for the unit and individual unit lessons and activities are discussed. (Author/JN)

Discusses need for and nature of science courses for the nonspecialist, outlining the content of an integrated four-year program devoted to sciences (first two years), technology (third year) and science/technology/human problems (fourth year). Includes recommendations for implementing such a program. (Author/JN)

Questionnaires were sent to biology, chemistry, physics, and earth science teachers (N=100) to determine practical problems at the student/teacher/subject matter interface. Responses related to importance of content area for students and difficulty students have in learning the content are discussed. (SK)
