Five forms of a basic science examination administered over three years in a national board testing program were analyzed to determine the stability of judged cut scores. Results indicate that cut scores derived from the modified Nedelsky procedure were within equating error of the Rasch equated cut scores over the five administrations. (SLD)

This study reports a multitrait-multimethod analysis of evidence relating to the validity of reporting on subdomains in science from national tests at age 14 in England and Wales in 1993. Data support the policy decision to report only a single test level. A multitrait-multiform analysis is also described. (Author/SLD)

Discusses teaching the names, symbols, and charges of 53 common ions along with those of the elements. Provides an ion quiz sheet. (YP)

By creating science achievement tests that satisfy cognitive fidelity and process relevance criteria, educators will produce achievement indicators that serve a reporting function and still benefit the educational system. The true test of students' understanding is hands-on assessment in a laboratory situation. Includes eight references. (MLH)

Determined is the logical reasoning necessary to construct line graphs including a straight line with a positive or negative slope and an exponentially increasing curve. The responses of subjects (grades 6-12) were classified into one of nine categories fitting with Piagetian operational structures. (Author/YP)

The misconceptions related to the concepts of force and acceleration among college students are explored. Misconceptions are identified and their occurrence among a large percentage of students are observed. Provided are some implications for physics teaching and an eight-item test. (Author/YP)

Describes the use of a laboratory-based exam in mechanics that makes students use metersticks, stopwatches, and spring scales to examine physical situations, make some calculations to predict what will happen, and then test their predictions. Includes a description of the lab stations for the actual exam. (JRH)

Considers how computers might help broaden assessment practices by examining the types of test items that might be used in computer environments. Explores ideas from cognitive psychology and research on problem solving. Contains 17 references. (DDR)

Explored methods for detecting gender-based differential item functioning on a science test that was part of the National Education Longitudinal Study of 1988. Exploration of conditioning variables and interviews with 25 high school students show a large male advantage for one item in particular. Discusses the basis of gender differences. (SLD)

Discusses the performance of 11th-grade students from Barbados, Belize, Jamaica, St. Lucia, St. Vincent, and Trinidad (n=1216) on an Errors in Biological Labeling Test (EBLT). Concludes that performance was low in six categories of errors, and that girls performed significantly better on each category of error than did boys. Contains 15…

After scrambling to raise students' skills in math and reading, state and school administrators are beginning to place renewed emphasis on science, with the approaching mandates of the No Child Left Behind Act (NCLB) squarely in mind. That effort is taking shape on many fronts, from the design of new tests in science subjects to the revamping of…

The purpose of this study was to examine the relationship between student understanding of the nature of science and their problem-solving strategies. Six hundred and twenty Year 8 students in Taiwan twice completed two conceptual problem-solving tests and a questionnaire on the nature of science. Four of these students were selected for follow-up…

Students hold a surprising number of ideas about the Earth's structure and process. This paper begins with a discussion on the nature of understanding in the conceptually confined domain of geosciences. There then follows a report on a study of the ideas about a range of concepts relating to "crystals", "volcanoes",…

This booklet is intended to help students do their best on the ACT. It summarizes general test-taking strategies, describes the content of each test, provides specific tips for each, and lets students know what they can expect on test day. Included in this booklet are complete practice tests--"retired" ACT questions that were administered to…

The purpose of this study was to investigate how photograph-based life science multiple-choice items influenced Louisiana science students' performance on statewide standardized tests, in comparison with text-based items about the same content. This mixed methodology research study focused primarily on types of multiple-choice items, specifically…
