While school textbooks are assumed to be written for and used by students, it is widely acknowledged that they also serve a vital support function for teachers, particularly in times of curriculum change. A basic assumption is that biology textbooks are scientifically accurate. Furthermore, because of the negative impact of…

Presents the results of a study that focused on incidences of prescribed textbook usage in Namibian science classrooms. Indicates teacher dominated textbook use and restricted range of textbook references per lesson. States that the teachers used textbooks for diagrams and data and to verify factual information. (CMK)

Investigated are the reasons why eleventh-grade Israeli students intend to enroll for a biology, chemistry, or physics course. Topics, activities, motives, attitudes, and grades in the subjects in year 10 are used as predictor variables for correlational analysis. (YP)

A great number of misconceptions in diverse subject areas as well as across age levels have been documented and described. Photosynthesis is one of the more intensively studied areas in biology. The purpose of this research was to carefully select and define misconceptions about photosynthesis needing remedial efforts. To achieve this, a specially…

THE RELATIVE EFFECTIVENESS OF EIGHT TYPES OF VISUAL ILLUSTRATION OF THE HUMAN HEART WAS TESTED IN NINTH THROUGH TWELFTH GRADE CLASSES. THE EIGHT TYPES--ABSTRACT LINE DRAWINGS, DETAILED SHADED DRAWINGS, PHOTOGRAPHS OF HEART MODELS, AND REALISTIC MODELS, EACH IN BLACK AND WHITE AND IN COLOR--AND A CONTROL PRESENTATION WITH NO ILLUSTRATIONS WERE…

The Louisiana Educational Assessment Program (LEAP) Grade 11 Test is designed to measure proficiency in four subject areas including English, mathematics, social studies, and science. This guide for science is intended to provide a description of the way in which specific skill areas are assessed on the LEAP test and instructional considerations…

The use and analysis of student generated propositions linking two scientific concepts (photosynthesis and respiration) were examined before and after the study of photosynthesis. A proposition-generating task (PGT) was used as a diagnostic tool to indicate student misconceptions and partial understandings. Focus was on determining: how the nature…

An investigation of biology matriculation tests in Israel was undertaken to assess the use of justifications with multiple-choice items and to compare the effect of three item formats on students' performance. More specifically, the study was designed to determine the: (1) extent to which justifications will differ if the correct answer is made…

The purposes of this study were to determine the level of achievement of United States advanced science students in an international context and to identify school factors affecting the science achievement of the students. The Second International Science Study (SISS) Advanced Science Achievement Tests included international common items which…

GRADES OR AGES: K-12. SUBJECT MATTER: Science. ORGANIZATION AND PHYSICAL APPEARANCE: The guide is divided into three sections, one each for elementary grades, middle grades, and high school. The first two sections are further subdivided by grade level and the last section is subdivided by course. Sections are laid out in four columns across two…
