Reformed Experimental Activities (REActivities) is an innovative approach to the delivery of the traditional material in an undergraduate organic chemistry laboratory. To better understand the fidelity of implementing this pedagogy and what effects the framework of REActivities has on student-instructor interactions, an observational protocol…

For many designers, freehand sketching is the primary tool for conceptualization in the early stage of the design process. However, current education on concept presentation techniques rarely emphasizes the construction of the most fundamental spatial unit, the cube. Incorrect construction of spatial units leads to disproportions that deviate from…

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,…

Emphasis on improving higher level biology education continues. A new two-step approach to the experimental phases within an outreach gene technology lab, derived from cognitive load theory, is presented. We compared our approach using a quasi-experimental design with the conventional one-step mode. The difference consisted of additional focused…

Several Web-based on-line judges or on-line programming trainers have been developed in order to allow students to train their programming skills. However, their pedagogical functionalities in the learning of programming have not been clearly defined. EduJudge is a project which aims to integrate the "UVA On-line Judge", an existing…

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)

In a senior modern physics laboratory, design" or ingenuity" experiments were introduced to acquaint students with methods of doing complete experiments. The former deals with proposed long term studies while the latter deals with apparatus and short term actual studies. Students rated the design" experiments higher. (Author/TS)

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)

Laboratory-based practical exercises, which are an important and time-consuming part of many science degree courses, may be directed towards a variety of learning objectives. Some of these have traditionally been assessed by staff marking the student's written account of the laboratory experiment (the laboratory write-up) but increasing student…

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…

Examines the role of computers in investigating teaching and learning processes and concludes that computer based experiments can be effective if they meet the same requirements that must be met by direct instruction techniques. (Author/DB)

To determine the effectiveness of an audio-tutorial technique in vocational agriculture, six treatment schools and six control schools were randomly selected from 48 Iowa high schools qualifying for participation in the study. While each school was provided the same reference material and teaching outline for the 14-day experimental period, the…
