Digital technologies have the potential to revolutionize education by enhancing quality, fairness, and efficiency. However, equitable access to these technologies remains a challenge. ILSAs (international large-scale assessments) have shown that the relationship between digital use and performance varies across countries and over time. To fully…

Describes the rationale, benefits, drawbacks, logistics, and student opinions regarding the idea of giving a two-minute quiz every lecture as a teaching reform that makes incremental changes, within the framework of the traditional lecture, in the direction of active learning. (JRH)

Presents a method for assessing three major objectives in the teaching of vocational and technical courses: material assimilation, application to real practical problems, and resourcefulness of the student. Provides examples of questions developed and compares them with questions normally used. (YP)

This was an experiment to test the extended discretion laboratory approach versus a guided-inquiry approach for teaching biology in a university setting. Among three criterion variables (examination, reports, and quizzes), only the laboratory report scores showed differences between groups and group-by-instructor interaction. (Author/YP)

Explains a scheme for grading student performance which stresses skills, technique, decision making, and notebook entries. Describes grading system and potential pitfalls. (RT)

Reported is a study of the relationships between the component skills involved in practical work assessment. Skills assessed included observing, manipulating, planning, interpreting, reporting, and self-reliance. The literature relating to inter-skill relationships is reviewed. (CW)

The Individualized Eclectic Examination is described. The format, design, and philosophy of the examination that emphasizes problem solving are discussed. Sample questions, student projects, and an illustration of the implementation of the exam are included. (CW)

Describes a laboratory activity "Observing Reactions in Solution." The activity can be used either as a laboratory or as a performance assessment for a high school chemistry class. (PR)

Develops the two-level small-group model based on cooperative learning seminars for inservice science teachers. Describes procedures to construct materials for the two-level group and suggests a teaching sequence. Summarizes research results about the two-level model and suggests implications of the model. (YP)

Proposes methods by which laboratory practical exams may be structured to assess outcomes from laboratory instruction. Presents eight general considerations for writing and using practical exams. Describes four example laboratory exams involving a box camera, circuit boxes, floating objects, and light. (MDH)

The objective of this study was to investigate how classroom questioning and discussion skills, designed to increase scientific literacy and problem solving performance, affects student achievement in biology and chemistry. The two independent variables for this study were the effects of wait time and supportive intervention. The dependent…

Described are the camps, competitions, and tests of the U.S. National Chemistry Olympiad. International competition, local exams, participating high schools, and national exams are highlighted. A summary of test results from the 1988 national examinations are presented. (CW)

The purpose of this set of materials is to provide the adult education teacher with the necessary information to assist their students in acquiring the content necessary for a basic understanding of science. The course consists of 25 lessons on basic biological and physical science concepts. The complete set of materials contains a student…

Describes the selection and implementation of an authentic assessment model for evaluating students' science laboratory knowledge and skills. Provides sample problems and a scoring form for the performance-based science laboratory test. (MDH)

A group of scientists and science educators has developed and pilot tested an integrated physical science program designed for preservice elementary school teachers. This document includes the syllabus and class materials for the Physics block of the physical science courses developed by the group. Included are diagrams, lecture notes, homework…
