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…

Students often complain that lectures requiring simultaneous writing and listening is a difficult task. An alternative method is provided to teachers to facilitate note taking by students. (ZWH)

Discusses how "live" experiments were combined with media packages and recorded lectures to allow coverage of more material and foster greater student/teacher interactions. Notes were distributed at the beginning of the semester which allow students to record experimental data from class demonstrations. Problems and suggestions for course…

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…

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)

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)

Teachers are provided with several experiments for primary students that address concepts related to the properties of air, sound, and water. (IAH)

Describes an inservice teacher workshop conducted in Pennsylvania which was designed to encourage the introduction of chemistry at the elementary school level. Discusses the organization and content of the workshop, the materials used, and some evaluative information provided by workshop leaders, teachers, and their students. (TW)

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)

Describes a two-week lesson on electric fields that combined lecture, interactive video, lab experimentation, computer spread sheets, and computer-assisted-graphing. (PR)

Presents a six-step problem-solving process which the author has used to present creative science investigations to fourth, fifth, and sixth graders. (Author/SJL)

Describes experiments designed to investigate the cooling rate of microwave-boiled water as compared to that of stove-boiled water. Concludes that within experimental limits, microwave-boiled water and stove-boiled water cool at the same rate. (JRH)

Explores strategies in the situation of a runner trying to evade a tackler on a football field. Enables the student to test intuitive strategies in a familiar situation using simple graphical and numerical methods or direct experimentation. (JRH)

You can't see, smell or taste air - but here's an easy method for experimenting with it. (Editor)

Points out the benefits of "sciencing"--helping children learn the methodology and processes of scientific investigation through the use of play experimentation. (SKC)
