The purpose of this empirical study was to establish initial reliability and validity data for a new Television Test of Science Processes (TTSP) which was developed in conjunction with the Science for the Seventies project of televised science instruction modules. Reliability was determined through internal consistency analysis using the…

This study was part of a project to develop science and technology (STS) issue investigation and action materials with the potential for use across science and social studies classes at the secondary level. Special emphasis was given to learning teachers' perspectives on the development of a unit on the impact of pesticides on society. Seven areas…

In an attempt to determine the level of questioning according to Bloom's taxonomy, generated by test items that accompany selected fifth-grade science textbooks, an analysis of the tests provided by three of the most commonly used elementary science textbooks was completed. Additionally this analysis examined the extent to which each series…

In the context of Phase Four of the National Assessment of Educational Progress (NAEP) Science Attribute Study, this report includes a discussion of item attributes, an overview of the item attributes used in the study, some psychometric characteristics of the blocks analyzed, a general description of the rule-space methodology, the results…

This study had three purposes. First, to develop and validate a criterion-referenced test to measure science knowledge of students who finished the second cycle of the Basic General Education (6th grade). Second, to assess the performance of the entire Costa Rican population of sixth graders and, third, to analyze the results according to some…

This study was designed to assess the effect of a process oriented elementary science curriculum upon students' achievement. The Iowa Tests of Basic Skills (ITBS) Complete Battery with the social studies and science supplements was administered to sixth grade students completing one, two, or three years of the Science through Discovery program in…

In a project on the development of performance assessments in science, researchers have developed four types of assessment: comparative, component identification, classification, and observation. They have noted that assessments belonging to the same type of task can be scored for the same performance properties. This paper reports on the…

This paper describes the results of a student science assessment test and teacher questionnaire surveying 424 sixth grade teachers in the province of Newfoundland and Labrador. The student test measures student attitudes to science and scientists, knowledge in life, physical and earth science, and student competence on 12 science processes…

A majority of the school districts that desegregate use magnet schools as part of their effort. Magnet schools offer enriched academic or vocational programs to attract committed students whose neighborhood schools do not offer the coursework and activities they seek. This paper is concerned with science magnet schools. This study was designed to…

This study examined the effects of linguistic simplification of fourth and sixth grade science test items on a state assessment on the achievement of English language learners, those of limited English proficiency (LEP). At each grade level, 4 parallel 10-item testlets were included on an operational statewide assessment. On each testlet, items…

The study described in this paper is part of an effort to improve understanding of the science assessment of the National Assessment of Educational Progress (NAEP). It involved the coding of all the items in the 1996 NAEP science assessments, which included 45 blocks (15 each for grades 4, 8, and 12) and over 500 items. Each of the approximately…

The development of the emerging technology of item writing was motivated in part by the desire to reduce potential subjectivity and bias between different item writers who attempt to construct parallel achievement tests. The present study contrasts four test forms constructed by the combined efforts of six item writers using four methods of item…

The objective of this project was to develop a valid and reliable multiple choice test of six basic science process skills for students in grades 4 to 8 (ages 8 to 14 years). Seven criteria were outlined for the test: an emphasis on the six most widely used science process skills (observation, inference, prediction, measurement, communication, and…

The purpose of this study was to determine patterns of gender and ethnic differences in science and mathematics achievement of fifth graders, taking into account student ability, item response format, and strands of learning outcomes. Subjects were 2,551 fifth graders from a large urban area in Ohio. The Ohio Off-Grade Proficiency Test was used.…

The perceptions of elementary school teachers toward the initiation of the New York State program evaluation tests (PETs) in science and social studies were studied. In New York, the PETs are intended to assess the local instructional program, rather than evaluate students. The social studies (grade 6) and science (grade 4) PETs were implemented…
