One theory of second language acquisition argues that children's competence in a second language is a function of the amount of "comprehensible input" acquirers receive and understand, without formal instruction in reading or grammar. To examine this hypothesis, this study analyzes whether comprehensible input in the form of captioned television…

This project developed a new kind of computer simulation and explored its impact on teaching and learning in introductory biology. The aims of the project were to: (1) develop a flexible simulation environment that would permit students to design, build, and test realistic simulations; (2) support student experimentation with intelligent tutoring…

At Raritan Valley Community College (RVCC) in New Jersey, an honors philosophy course was developed which taught mathematics and science concepts independent of computational skill. The course required that students complete a weekly writing assignment designed as a continuous refinement of logical reasoning development. This refinement was…

A study examined the effects of an instructional intervention designed to improve high school students' ability to comprehend the gist of biology text materials. Subjects were divided into a strategy group, a read-study group, and a control group. The strategy subjects were given eight days of instruction in a procedure designed to help them…

Provided are edited background papers prepared for a Meeting of Experts on the Incorporation of Science and Technology in the Primary School Curriculum. Papers are organized into four major sections. Section 1 is concerned with such topics as the rationale and objectives of science and technology in primary schools, selection of appropriate…

Selected articles on various aspects of biology teaching published in 1979 have been annotated in this two-part bibliography. Entries from 18 journals representing 11 different countries are presented according to a topic area classification scheme listed in the table of contents.

This activity unit on human and medical genetics for junior high and middle school students emphasizes variability and diversity in genetics. Twenty-five activities are organized into five sections: (1) individual differences among human beings; (2) causes of similarities and differences among humans and between generations; (3) variety in living…

Difficulties encountered by first-year teachers of science and mathematics; were investigated in this study conducted in May 1981 in Illinois schools as part of a broader study involving teachers in other subject areas as well. A questionnaire was designed and mailed to 138 science and 104 mathematics teachers. Responses were received from 46…

Intended to help elementary and secondary students develop a global perspective, this manual contains ready-to-use lessons and activities dealing with the concept of communication. The materials can be used in individual courses in the social studies, language arts, and science, or in interdisciplinary courses. The activities in part 1 deal with…

This three-part yearbook begins with a characterization of science education practices based on extensive national studies conducted during the period 1977 to 1983 and a discussion of several efforts which address the current crisis in science education. The second part consists of essays focusing on practical, program, and on political and policy…

A follow-up study was conducted, using a sample of 10 teachers from two of five school districts that participated in an original project on wait time and classroom interaction. A workshop was conducted focusing on the elements of classroom discussions. In this workshop, transcripts containing short wait times were contrasted with ones with longer…

The aim of the Learning in Science Project is to: (1) investigate science teaching/learning at the Form 1 to 4 level (ages 10 to 14); (2) identify some of the key difficulties in this subject area; and (3) find ways of overcoming such difficulties. The project is seen both as an evaluative and a research project in that it is concerned with…

The first working paper of the Learning in Science Project, "An Initial Framework," outlined what was then seen as the major aims of the project and suggested how these aims might be achieved by three phases of research: exploratory (to observe teaching/learning in Form 1 to 4 science classrooms and to identify difficulties perceived by…

One area explored in the second (in-depth) phase of the Learning in Science Project was "children's science," defined as views of the world and the meanings for words that children have and bring with them to science lessons. The investigation reported focuses on students' thinking regarding their views on gravity. Students (N=42) were…
