We report on the development of a new instrument for measuring teachers' knowledge of language as an epistemic tool in science classes. Language is essential for science learning, as all learning requires the use of language to constitute one's own ideas and to engage with others' ideas. Teachers with knowledge of language as an epistemic tool can…

The present study reports the development of a brief, quantitative, web-based, psychometrically sound measure--the Generalized Acceptance of EvolutioN Evaluation (GAENE, pronounced "gene") in a format that is useful in large and small groups, in research, and in classroom settings. The measure was designed to measure only evolution…

Though addressing sources of uncertainty is an important part of doing science, it has largely been neglected in assessing students' scientific argumentation. In this study, we initially defined a scientific argumentation construct in four structural elements consisting of claim, justification, uncertainty qualifier, and uncertainty…

The purpose of this article is to address a major gap in the instructional sensitivity literature on how to develop instructionally sensitive assessments. We propose an approach to developing and evaluating instructionally sensitive assessments in science and test this approach with one elementary life-science module. The assessment we developed…

The Trends in International Mathematics and Science Study (TIMSS) is a comparative assessment of the achievement of students in many countries. In the present study, a rigorous independent evaluation was conducted of a representative sample of TIMSS science test items because item quality influences the validity of the scores used to inform…

Explores variables influencing the cognitive emphasis of teachers' examinations. Examination questions from Nigerian secondary school science teachers were analyzed according to Bloom's Taxonomy. The influence of the following variables on levels of questions was investigated: teachers' educational backgrounds, subjects taught, grade level taught,…

The paper documents experiments designed to compare essay and multiple-choice tests as means of testing science learning. Results indicate it is easier to score high on multiple-choice tests; some students substitute quantity on essay tests; and essay tests reveal weaknesses hidden by multiple-choice tests. (RE)

Investigates two evaluative hypotheses related to test item sequence and the performance of the students who take the tests. (SA)

The current status of "homemade" achievement tests reported in "Journal of Research in Science Teaching" and "Science Education" (January 1975 to January 1980) is examined using Anderson's (EJ 062 750) eight categories of information that a high quality research report should include. Findings from 142 references…

Describes a paper-and-pencil test for high school biology students measuring science process skills, such as developing hypotheses; making predictions; identifying assumptions; analyzing data; and formulating conclusions. Reports some data on reliability and validity of the test. Provides all 35 items of the test. (YP)

Reviews procedures followed in developing a set of science items for Chemistry, Physics, Biology, Geology content areas and examines the items' construct validity in relation to a specific technique of evaluation. Analysis supported the items' construct validity and viability for testing certain science skills at the secondary level. (ML)

This study reports on the development and validation of the Attitude toward Science in School Assessment (ATSSA). Reports a low correlation between attitude and achievement tests while a moderate correlation between attitude and course grade. (Author/YP)
