Stellar parallax is a concept that is dealt with infrequently in the high school classroom other than by qualitative consideration of stereoscopic parallax and argument by analogy. Use of stellar parallax for distance determination can be difficult for students to understand without some type of hands-on experience to explore the concept. Thus,…

In this paper, the author first cites passages that highlight the key developments and dilemmas of teacher education in Ghana in the 1960s, when the new nation resolved to prepare its largely untrained teaching force in "progressive" methods. Across the decade--and across subject areas--Ghana conducted in-service teacher training to…

There are no fewer than three dozen scientific groups dealing with problems of the development of methods of teaching physics, chemistry, and biology in this country; they are working in pedagogical and classical universities and in institutes of the Russian Academy of Education. Innovative schoolteachers are involved in this endeavor as they…

Hearing-impaired students (32) and staff (25) of a 4-week summer program were interviewed. Among the conclusions are that teachers of hearing-impaired students should expect heterogeneity in terms of their preferred mode of communication, reading ability, lip reading ability, interest in science, etc. Effective instructional techniques include…

Presented is an evaluation of a leadership training program to prepare junior high school teachers to use the Introductory Physical Science Curriculum. Emphasis of the leadership program is on administrators and their problems, leaders and their problems, and teachers. Recommendations are given. Included in the appendices are sample letters of…

Compared the laboratory method versus lecture method for Nigerian grade eight students (n=210). High achievers in both groups had identical achievement, but the low achievers in the laboratory sections performed better than students receiving the lectures. Females receiving lectures performed better than the males receiving lectures. (PR)

Describes Irish secondary science and discusses the management of science in schools. Identifies two key features of Irish school science, the collegiate nature of science departments and the difficulties in carrying out practical work. (MM)

Provided in this book is a critical review of modern biology curricula and teaching methods with particular reference to the advance of knowledge and changes in society. The book consists of an introduction (discussing biology as a subject, attitudes to learning, and values in biology teaching), 12 chapters, and 4 appendices. Teaching/learning…

Describes the development of a two-week National Science Foundation (NSF)-funded course at the Virginia Military Institute to promote the lecture demonstration technique. (SK)

This book aims to raise questions by addressing the ways that teaching can and should be reflective practice. Throughout the book the question, "How can teachers continue to evolve and rethink their teaching methods?" is addressed. Tracking six prospective biology teachers from their university training through their first years in the classroom,…

Studies indicate that there are attitudinal problems toward chemistry that keep students from achieving relevant objectives; thus, positive attitudes need to be developed by having a learning environment that fosters a warm and relaxed atmosphere in which students feel accepted and are willing to take risks in achieving complex objectives.…

The development of the earth science curriculum in the nation's secondary schools led institutions of higher education to develop diverse methods of structuring new earth science courses and to develop new teaching methods for potential earth science teachers. Although numerous guidelines have been developed by experts, little has been done to…

Most pupils to whom science is taught in schools will not afterwards be in a position to 'do science. Are they to be left in the hands of the 'doers'? (Editor)

Describes techniques to help introductory students become familiar with Avogadro's number and mole calculations. Techniques involve estimating numbers of common objects then calculating the length of time needed to count large numbers of them. For example, the immense amount of time required to count a mole of sand grains at one grain per second…
