In this study the authors set out to better understand the relationship between teacher knowledge of science and student learning. The authors administered identical multiple-choice assessment items both to teachers of middle school physical science and to their students throughout the school year. The authors found that teachers who have strong…

We have conducted an investigation into how well students in introductory science classes (both physics and chemistry) are able to predict which questions they will or will not be able to answer correctly on an upcoming assessment. An examination of the data at the level of students' overall scores reveals results consistent with the…

In order to be successful in an educational setting, a student must acquire a particular register of language specific to academia, or an academic register. It cannot be acquired through ordinary social intercourse. It is specific to school. Acquiring the academic register is the greatest challenge English Learners (EL) face during their academic…

As the number of college students studying science continues to grow, it is important to identify variables that predict their success. The literature indicates that motivation and learning strategy use facilitate science success. Research findings show these variables can change throughout a semester and differ by performance level, gender and…

This research was designed to investigate the relationship between a verbal measure of predictive ability and performance on selected science process tasks by prospective elementary school teachers. The vehicle utilized for assessing the comprehension ability was the cloze procedure, with the cloze score being considered as verbal predictive…

Describes a simulation method for measurement of errors that requires calculators and tables of random digits. Each student simulates the random behaviour of the component variables in the function and by combining the results of all students, the outline of the sampling distribution of the function can be obtained. (GA)

Eight kinds of estimation activities are described and discussed. Nine activities which range from kindergarten to twelfth-grade level are suggested. (MK)

Chemistry pretest scores, high school chemistry grades and, to a greater extent, math SAT scores were useful predictors of college general chemistry grades. Regression analysis of all these predictors combined was used to construct an expectancy table which is being used to identify and advise underprepared students. (BB)

This study was designed to help students decide whether or not to register for a general chemistry course. High school grade point averages (GPAs) and American College Testing (ACT) scores were obtained on over 600 students from New Mexico State University and were entered into correlation analysis with chemistry grades. A "Chemistry…

Seventeen structure-of-intellect (SI) abilities were tested as predictors of success in a Conceptually Oriented Program in Elementary Science (COPES) unit. Three SI abilities involving convergent productive thinking and one involving divergent productive thinking were shown to be significant predictors. (MLH)

A method of assessment using six one-hour tests, with provision to repeat four of them, is described. Performance in the course, high school background, and the first test's results are used to determine entry criteria for the course. (MSE)

This project was the result of the Navy's increasing manpower needs for high quality officers with engineering and science training and the desire to have larger numbers of midshipmen elect engineering and science majors at the Naval Academy. In order to accomplish this, a Strong Vocational Interest Blank (SVIB) was created to aid in selecting…

Reports the results of a study conducted at the Israeli Science Teaching Center, Hebrew University of Jerusalem, which attempted to correlate the Teacher's Image'' with actual student achievement in science. (JR)

Characterized the methodology of case studies, using examples from science education, with regard to their potential for the analysis of innovation and formulation of emerging trends. The theoretical and empirical support of evaluation will generate a call for negotiation as the formula that regulates the assessment of a program's efficiency and…
