Compared "extended discretion" (ED) learning approach to traditional Biological Sciences Curriculum Study (BSCS) laboratory investigations. Found that although ED students are more capable of exercising independent judgment for greater lengths of time while BSCS demanded more teacher time, all teachers were still reluctant to accord…

Some applications of ratio and proportion to scale drawing involving geometric figures are given. The activities or problems concern the earth and space, scale speeds, and the earth-moon system. (MNS)

Describes an instructional approach which focuses on writing skills as a means of promoting science learning. Gives examples of science writing and research activities for grades two and six. Also discusses the goals, procedures, and results of the project. (ML)

Encourages the use of imaginative writing about scientific phenomena and/or principles. Offers samples of student writings on the concept of succession. Includes a listing of topics which could be used for creative writing exercises and provides suggestions for classroom implementation. (ML)

Advocates inclusion of science, technology, and society (STS) approach in the science curriculum, focusing on curriculum development. Offers examples of using solar energy as an integrating theme for science, technology, and society topics and explains several energy curricular materials. (ML)

Tested the effectiveness of a program designed to teach children how to conduct and interpret a controlled experiment. Results indicate that the ability to control variables can be taught using the program (which consists of activities related to designing, building, and launching model rockets). (JN)

Providing science education for all students is a challenge for educators around the world. In an effort to help educators answer this challenge, earlier attempts at providing science for all are examined. (RM)

Investigated changes that occurred in sixth- and seventh-grade teacher and student discourse when teachers endeavored to implement extended teacher wait-time in a sequence of seven lessons related to probabilistic reasoning. Results indicated that teacher wait-time increased from an average of 1.9 to 4.4 seconds during the lesson sequence. (JN)

Preliminary analysis of the Second International Science Study shows, counter to trends in recent studies, improved overall science scores among fifth and ninth graders compared to the 1970s. In particular, fifth graders know more about biology and physical sciences and less about space travel compared to the 1970s. (JN)

Reports on effectiveness of an elementary school science program comparing attitudes toward science of Science Curriculum Improvement Study (SCIS) students and teachers with those of students and teachers in non-SCIS classes. Students (N=456) indicate preference for SCIS process-approach science, and SCIS teachers (N=109) spend more time teaching…

Defines microcomputer-based laboratory (MBL); discusses necessary hardware and software for operation of an MBL; reviews science applications in secondary education and eight steps involved in constructing a four-paddle interface box, the heart of an MBL; and provides information on suppliers of resources for creating an MBL. (MBR)

Describes the origin, development, and activity options of the Hands-On-Science Program. Explains the program's process-oriented, interdisciplinary approach, its staffing procedures, and activity format. Lists the current and future locations of the program. Also provides an example of an activity on solar energy for primary level students. (ML)

Reports on participant-observation in a third- and fourth-grade classroom in which students learned to read science texts with both "efferent" and "aesthetic" reading processes. (HTH)

Presents the Language-Experience Approach (LEA) of teaching beginning and remedial reading, describing how it may be used in the science classroom. Provides step-by-step instructions on how to incorporate the LEA into science laboratory activities and gives tips on how to structure the class to accommodate different levels of readers. (JM)

Describes an integrated approach to science instruction using large group, small group, and audio-tutorial sessions to teach students to master content, express themselves in written and oral presentations, and critically assess and organize material. Provides the orientation "Why are we all here?" and defends criticisms of cheating and…
