Describes a fourth-grade unit on density which introduces a concept useful in the study of chemistry and procedures appropriate to the chemistry laboratory. The hands-on activities, which use simple equipment and household substances, are at the level of thinking Piaget describes as concrete operational. (BC)

Determined perceptions of science education faculty and graduate students (N=195) concerning how the relative emphasis of major science education objectives should change in grades K-12. Also determined extent of agreement among subjects on the emphases and identified extent to which personal characteristics of subjects related to differences in…

Determined if differences in performance on a posttest (in which sections differed in use of manipulative models to answer questions) were attributable to differences in reasoning levels of chemistry students (N=105). Results indicate that reasoning may affect performance under conditions of constant instruction. (JN)

Describes science education programs established in Indonesia for high school graduates. The one-, two-, and three-year programs were established in response to the severe and growing shortage of secondary teachers in this country. A complementary inservice distant learning scheme to upgrade semi-qualified graduates of these programs is also…

Describes simple, electrical projects with dry cell batteries and lamps designed to teach children about conductors, insulators, and switches. Instructions for construction of circuits, the science ideas in each project, and suggestions for extending each of the investigations are included. (JM)

The National Institute of Education has supported new research and synthesized existing information to provide teachers and administrators with direction for cognitive instruction. Efforts have been made to identify kinds of thinking and learning conducive to success in particular subjects and to offer useful research-based ideas to teachers. (TE)

Describes the development of the Nuffield chemistry curriculum materials by chemistry teachers and how these materials were received and used by a much larger and representative group of the profession. Includes comments on teaching Nuffield chemistry, the Nuffield examination, and on Nuffield chemistry outside of Great Britain. (JN)

Discusses several aspects of physics education in China. These include the school system, physics curriculum, physics textbooks and reference books used, preservice training for teachers of senior and middle schools, and in-service programs and activities for qualified physics teachers. (JN)

The third of three parts (previous parts include SE 534 217 and 534 404) reports on the characteristics of middle school science teachers as well as sample programs and inservice activities for these teachers. Included are some research concerns related to middle school science instruction. (JN)

Investigated effects on meaningful learning achievement of concept-related instructional organization and locus of control orientation of 541 high school students. Indicates that externally-oriented subjects exposed to the treatment generally retained more than those in a comparison group. Other results are reported and discussed. (Author/JN)

In the spring and summer of 1995, the National Science Foundation (NSF) funded the first cohort of eight projects in a new initiative, the Local Systemic Change through Teacher Enhancement (LSC) program. Eighteen additional projects were funded in 1996, 20 in 1997, 12 in 1998, 13 in 1999, 9 in 2000, 7 in 2001, and 1 in 2002 for a total of 88…

The Effective Access (EA) team conducted a limited, multi-level investigation of high school science, technology, engineering, and mathematics (STEM) educators and their use of digital objects. The team attempted to answer the following questions to identify teachers' unique needs in the digital library environment, to provide a better…

Just as middle schoolers are "wired" to learn in active, hands-on ways, this book is wired to help teachers spark a vital connection to these students to keep them tuned-in to science. "Doing Good Science in Middle School" combines practical insights about adolescent learners with what master teachers know about how to shift from passive,…

Like a search engine for science teachers, How to... "Weave the Web into K-8 Science" is a custom-made guide to bringing the best of the Internet into the classroom. Author David Wetzel has done the work of locating online materials. The book offers resources for Web-based science teaching and learning plus online technical help for both…

In times when human beings used to live in a natural environment, their needs were also provided for by natural resources. With the increase in population over time, human beings started to look for new resources willing to get "the most" and "the fastest". Just like the invention of steam, first, they increased the density of the resources and…
