Determined importance of transition between a student's initial collegiate science experience and the decision to continue in science, and whether reasons students give to explain their success or failure in their first course are related to that decision. Results demonstrate a sense of competence for students who continue in science. (Author/JM)

Human expert problem-solving in science is defined and used to account for scientific discovery. These ideas are used to describe BACON.5, a machine expert problem solver that discovers scientific laws using data-driver heuristics and "expectations" such as symmetry. Implications of BACON.5 type research for traditional science education research…

Agrees that the conceptual validity of the Scientific Attitude Inventory is suspect and a conceptual reanalysis of the distinction between "attitudes to science" and "scientific attitudes" is needed. However, inquiry into whether such instruments are developed consistently with formal criteria and theoretical guidelines of social psychology is…

Two areas of research were explored in this meta-analysis: comparison of inductive versus deductive approaches and use of advance organizers. The study involved 128 characteristics for 39 studies spanning the period from 1957 through 1980. Coding variables included 57 concerned with treatment features and 12 with outcome attributes. (Author/JN)

Presents a logical analysis of three vector concepts (position, displacement, velocity) in terms of their constituent characteristics and shows how they can be used to structure an empirical investigation into students' prior knowledge about these characteristics. Reports results of students' (N=20) conceptions about the vector characteristics…

Describes aspects of qualitative research having the potential of providing guidance to change agents in designing effective strategies to bring about desired changes in science education. A discursive approach involving the method of collecting and simultaneously analyzing data ("grounded theory") is described. (Author/JN)

Examined relationships between teaching behaviors and student engagement in 13 middle school science classes. Results indicated that seven managerial variables and four instructional variables were significantly related to student engagement rates. Types of tasks allocated by teachers were also significantly related to types of tasks undertaken by…

Investigated whether differences existed between gifted (N=25) and nongifted (N=25) fifth graders and between the sexes and related subgroups with respect to attitudes toward science. Although results indicated that gifted students had more positive attitudes than nongifted students and boys had more positive attitudes than girls, the findings…

Investigated the validity of the assumption that arranging items in objective tests in order of increasing difficulty increases student motivation and produces more reliable tests. Results indicate that test reliability was largely independent of item sequence. (Author/JN)

Compared effectiveness of two inservice programs differing in length (long: N=296; short: N=140) and energy-related content on teacher attitudes. Although programs had differing effects on attitudes toward curriculum change and beliefs about science and science education, effects on teachers' opinions on energy issues were the same. (JN)

Investigated relationships between visual-spatial abilities and achievement and what influence these abilities have on the high attribution rate characteristic of many introductory college-level science courses. Results, among others, using physics students (N=136) and nonscience majors (N=52), indicate that visual-spatial abilities influence…

Determined effects of various methods and formats on subjects' (N=253) responses to a Piagetian reasoning problem requiring control of variables. Results indicate that format but not method of task administration influences subjects' performance and that the influence is similar for various combinations of methods and format. (Author/JN)

Compared levels of formal operational thought of students tested before and after entering science programs. Results indicate considerable numbers of students at transitional levels on each occasion, low correlations between cognitive level and grades, and significant development in levels of cognitive thought during the National High School…

Investigated women's (N=35) aptitude for and changes in skills during an engineering training program and the relationship between academic/demographic information and cognitive skills to success in the program. Compares results with those of studies of male undergraduates. Includes results of mathematics anxiety and conservation of horizontality…

Discusses the science education research agenda from the viewpoints of learning theorists, political and social scientists, counseling psychologists, cognition psychologists, and pedagogical researchers. Indicates that a broader perspective of these areas helps to link the research agenda to science teachers' questions/concerns, and to such areas…
