The main purpose of this study was to enhance student understanding of the scientific concepts of chemical reaction rate. Forty-four grade 11 students were the target group. The treatment tools were seven learning plans of 5E inquiry incorporated with an analogy learning approach during 15 hours of class time. In each learning plan, the students…

The current review examined modeling literature in top science education journals to better understand the pedagogical functions of modeling instruction reported over the last decade. Additionally, the review sought to understand the extent to which different modeling pedagogies were employed, the discursive acts that were identified as important,…

Discusses the use of student-generated rubrics in science classes where students design their own laboratory activities to solve open-ended problems. Promotes careful consideration of what constitutes open-ended work. Presents certain rubrics and grading criteria. (JRH)

Describes an approach to incorporating cooperative learning into the anatomy laboratory without diminishing the quality of instruction of the subject matter. Discusses the background, organization of groups and group tasks, evaluation of the approach, and potential disadvantages of cooperative learning. Contains 11 references. (JRH)

Described is an introductory materials science laboratory program which emphasizes crystal structure both on the atomistic and microscopic scale and the dependence of materials properties on structure. The content of this program is classified into four major areas: (1) materials science, (2) mechanical behavior of materials, (3) materials testing…

Discusses the value of laboratory work, suggesting that it is not superior to other aids such as computer simulated experiments (CSE). Advantages of and problems related to use of CSE in the classroom, responses to criticisms of simulated laboratory work, and evaluation of CSE as a teaching aid are considered. (JN)

Compares between the component and the modules (system) approaches which are used to teach electronics at Croydon High School, Australia. The author presents some personal views from his experience of teaching both ways. (HM)

Describes an investigation of the associations between students' perceptions of laboratory environment and their attitudinal, cognitive, and practical performance outcomes. Assesses student outcomes in three distinct areas: (1) student attitudes; (2) achievement on a written examination; and (3) practical performance, specifically in the biology…

Presents performance assessments, written by a team of Wisconsin science teachers, designed to see if students know, have practiced, and are able to perform the skills associated with science problem solving. (JRH)
