This article seeks to provide researchers and practitioners in laboratory education, particularly those involved in the curriculum design and implementation of teaching laboratories at university level, with a conceptual framework and a working model for an integrated assessment of learning domains, by attending to a more holistic approach to…

Describes structured and open-ended evaluation techniques that permit students in a reading center to rate their own reading performance. (FL)

A set of supplemental materials for teaching grade 7 life sciences to beginning and intermediate students of English as a second language (ESL) includes an introductory section on teaching the ESL student and six instructional units. The introductory section discusses the special classroom needs and characteristics of the ESL student and provides…

Describes the infrared analysis of geological specimens which can form the basis of a laboratory exercise, allowing some minerals to be identified by "fingerprint" technique. Students can gain insight into the concept of symmetry and environment around an atom. (Author/SA)

Reviews studies focusing on practical assessment in science. Areas considered include what students are really doing in laboratories, how practical skills should be assessed, methods used to assess practical science (such as internal/external examinations and continuous assessment), methodological issues, and reasons for the failure of some…

Describes a performance assessment protocol that rates six goals: (1) methodology of research, (2) use of equipment, (3) accuracy in measurement, (4) application of concepts and formulas, (5) use of mathematics, and (6) completeness and clarity. Provides an example performance task evaluation sheet. (MVL)

Reviews background of atomic absorption spectrometry techniques. Discusses problems encountered and precautions to be taken in determining trace elements in the parts-per-billion concentration range and below. Concentrates on determining chromium in biological samples by graphite furnace atomic absorption. Considers other elements, matrices, and…

Describes different evaluation techniques of student performance in the science laboratory. Evaluation techniques discussed include written reports, test items, practical tests, and observational assessment to evaluate both student performance and to promote development of specific skills. (DS)

Two studies investigated interrater agreement among 10 clinical dental examiners who scored residual subgingival calculus after student scaling on 4,160 real and 92 manikin tooth surfaces. Interrater reliability was low. Results suggest a need in periodontics for effective examiner calibration methods and objective subgingival calculus detection…

Discusses the need for student research-type chemistry projects based upon "unknown" metal complexes. Describes an experiment involving the product from the reaction between cobalt(II) chloride, ethane-1,2-diamine (en) and concentrated hydrochloric acid. Outlines the preparation of the cobalt complex, along with procedure, results and…

Describes an experiment designed to introduce biochemistry students to the specificity of an analytical method which uses an enzyme to quantitate its substrate. Includes the use of toxicity charts together with the concept of the biological half-life of a drug. (TW)

Discusses the need for student experiments involving the complete characterization of "unknown" inorganic compounds. Describes a project employing a complex metal compound. The compound contains six different components in both inert and labile complexions. Outlines the complete procedure and the preparation of the unknown compound. (TW)

This six-chapter guide is designed to help Georgia teachers adopt or adapt various options into the local school's science curriculum. Major areas addressed in the chapters are: (1) secondary school curriculum development (focusing on performance objectives, sequencing the curriculum, evaluation, and scientific literacy); (2) teaching methods…

The articles in this collection focus on reading, learning assistance, developmental education, and tutorial services at the college level. Topics of the 28 articles include the following: (1) a reassessment of the state of learning assistance; (2) a reaffirmation of the role of developmental instructors; (3) human brain research, cognitive…

A University of Toronto pharmaceutics course which organizes information about physical chemistry around real problems, presented as case studies or laboratory projects, is described. Problems were addressed in class discussions or by unsupervised eight-student groups using self- and group evaluation procedures. Results are discussed, and three…
