This unit on hydrocarbons is one of 10 first year units produced by the Independent Learning Project for Advanced Chemistry (ILPAC). The unit is divided into sections dealing with alkanes, alkenes, alkynes, arenes, and several aspects of the petroleum industry. Two experiments, exercises (with answers), and pre- and post-tests are included.…

This report presents a statistical profile of secondary science teachers in grades 7-12 in North Carolina public schools. Data are provided and discussed in 9 sections under these headings: (1) basic information (teachers, subject and student membership, certification, and subject and certification areas); (2) subjects and certification; (3)…

This study compared attitudinal data on students who had dropped college preparatory science (academic terminal) in high school (N=55) with those who continued to enroll (academic continuing) in college preparatory science courses (N=108). Eight attitudes that have been hypothesized to be related to learning cognitive performance and enrollment in…

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 the concept of "light" held by 36 students. Data were obtained…

The Learning in Science Project established that children from a young age construct out of their everyday experiences views which they use to explain their world and that these views are remarkably resistant to replacement by scientifically more useful views. Although science lessons tend to be based upon activities which are designed by teachers…

The Learning in Science Project has adopted the view that science teaching might be improved if teachers can be given some appreciation of students' views of the world and the beliefs, expectations, and language that learners bring to new learning situations. This investigation focuses on the views that children (N=34) may have about rocks and…

This book provides job descriptions and discusses career opportunities in various fields of the biological sciences. These fields include: (1) biotechnology, genetics, biomedical engineering, microbiology, mycology, systematic biology, marine and aquatic biology, botany, plant physiology, plant pathology, ecology, and wildlife biology; (2) the…

This study tested the validity of the prevalent assumption that a teacher's understanding of the nature of science, in and of itself, is related to changes in the conceptions of his/her students and identified the classroom dimensions (such as teacher behavior and classroom ecology) significantly related to changes in students' conceptions. Data…

This study determined the status of marine education inclusion into K-12 lessons in North Carolina and reflected some inservice parameters. Analysis of a statewide, K-12 survey indicated: (1) 86% of the teachers responding taught some marine concepts in their classes; (2) the criteria for accessing information differed significantly among primary,…

The ue of hands-on models in teaching protein synthesis, in comparison to traditional expository methods, has been shown to improve the content achievement of biology students. The purpose of this study was to evaluate a set of models and the accompanying laboratory exercises in terms of content achievement and attitude toward biology and…

This paper discusses the implications of Piaget's theory to science education. The first section of the paper, "What Science Teachers Need To Know: Scientific Knowledge and Its Source," describes three sources of students' knowledge and corresponding educational practices. The second section, "Functions of Intelligence," discusses the concept of…

The Educational Technology Center (ETC) Complex Systems Project was initiated to explore ways of using computers to help students understand systems which have often proven too complex for most high school students to understand. Preliminary work concentrated on the cognitive processes involved in modeling simple systems. This paper describes an…

The goal of the Educational Technology Center (ETC) Computer-based Conferencing Project has been to explore the potential of computer-mediated communication to support teachers in collegial exchange about their subject and practice, and to develop recommendations for future applications and management of such conferences. The purposes of this…

Developing a constructivist view of scientific inquiry and knowledge is considered to be important to the training of future scientists, as well as to the understanding of scientific information by all citizens. The research reported targets the junior high school grades. Curricular materials that introduce seventh graders to the constructivist…

The purposes of this study were to determine how experienced high school physics teachers were in using computers, how computers were being used for high school physics instruction, what the teachers perceived the use of computers in their physics classes should be, and what the enabling and constraining factors were in developing the use of…
