Examines children's ability to formulate testable hypotheses, both from a theoretical viewpoint and from results of a British study of responses to an assessment instrument. Addresses implications for science education and difficulties in judging whether a child has demonstrated the skill. Concludes that evidence presented by teachers about…

The problem-solving behaviors and genetics concepts employed by experts and novices during interaction with the computer simulation CATLAB, were examined. Thirteen subjects (3 experts and 10 novices) investigated a common hypothesis on a specific genetic trait during the computer activity. Using naturalistic research methods, general patterns of…

The statistical power of analysis of covariance (ANCOVA) and its advantages over simple analysis of variance are examined in some experimental situations, and an algorithm is proposed for its proper application. In nonrandomized experiments, an ANCOVA is generally not a good approach. (SLD)

Compares Malawi's study center system of secondary education, involving community centers, distance education institutions, radio programs, and self-instructional materials, with traditional secondary schools with regard to cost, access, full-examination passes, and subject passes. Finds that study centers increase access to second-level education…

The grade improvement program "Where There's a Will There's an A" was evaluated with 36 experimental and 37 control group undergraduates. The approach and content of the evaluated materials appear inconsistent with the body of research on academic improvement, and study results do not indicate any improved achievement. (SLD)

Criterion-related validities of 2 laboratory practitioner certification examinations for medical technologists (MTs) and medical laboratory technicians (MLTs) were assessed for 81 MT and 70 MLT examinees. Validity coefficients are presented for both measures. Overall, summative ratings yielded stronger validity coefficients than ratings based on…

Studied the effect of grading classroom communicative activities on student performance at two different levels. Results indicated no significant difference in scores between the experimental and control groups at either level. (10 references) (VWL)

A survey by the European Pharmaceutical Students' Committee of its member countries investigated the extent of problem-based learning, the effectiveness of examinations for testing knowledge, role of English as the language of instruction, best teaching methods, and relationships with other health occupations. Results and a position statement are…

Addresses three issues concerning the assessment of the overrating and underrating of academic competence: (1) the impossibility of separating effects of overrating and underrating from effects of perceived and actual competence; (2) the questionable validity of Connell and Ilardi's method; and (3) the proposal of a new method and its implications…

A survey of 100 universities revealed test types, cut-off scores, and processes for testing language proficiency and performance of international teaching assistants. Results indicated the tests are complicated, time-consuming, and politically sensitive. Issues emerging include department role, use of adjustment period before teaching, and…

Focuses on the recent application and interpretation of the Fourth Amendment to school children. Discusses the amendment in regard to the relationship between school authorities and children, students' legitimate expectation of privacy, reasonableness in justification of a search, issues of mass mandatory screening, and requirements of due process…

Adopting an inquiry approach to teaching by learning the techniques of classroom assessment can give an instructor a much clearer picture of how his teaching affects student learning. This chapter describes the approach and how it is being used in a variety of classrooms. (Author/MLW)

Describes a study conducted at the University of Guelph that compared the learning achievements of a computer-administered mastery testing approach with a seminar-discussion approach. Pretests and posttests are described, student opinions are reported, and results are reported that indicate mastery/testing generated higher learning achievement.…

Number-correct scoring was compared to empirical option weighting for estimating domain scores and making pass/fail decisions that are typical of certification, licensing, competency, and proficiency testing. The usefulness of the option-total correlation option-weighting method was illustrated with a sample of 1,000 high school students. (SLD)

The study examined use of a curriculum-based measurement computer program to first, evaluate phonetic patterns in four spelling curricula and second, help special education teachers (N=27) identify students' phonetic spelling errors. Results indicated similarities among curricula and effectiveness of the ongoing feedback on teachers' skills. (DB)
