Enzymes are nature's catalysts, mediating chemical processes in living systems. The study of enzyme function and mechanism includes defining the maximum catalytic rate and affinity for substrate/s (among other factors), referred to as enzyme kinetics. Enzyme kinetics is a staple of biochemistry curricula and other disciplines, from molecular and…

"Multimodal Signs of Learning" proposes a methodology to uncover evidence of learning in students' multimodal compositions. Informed by social semiotic theory, the book tracks representation of subject content from physical and embodied teaching resources to students' handmade artefacts and physical presentations. Using materials from…

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…

There is a growing national recognition that teachers and teaching are at the heart of successful educational reform. However, few tools exist for measuring classroom instruction. The primary purpose of this article is to describe methods we developed to measure and study teaching, specifically while teachers were using a multimedia intervention…

Biology and chemistry graduates (n = 29) on a one year, post graduate, initial teacher training course were asked about their perceptions of written lesson appraisals produced by mentors when observing their teaching. Data were collected using the same open questions at three points in their course. The data relating to mentors who had received…

Although researchers in higher education propose alternatives to traditional approaches to assessment, traditional methods are commonly used in college or university science courses. The purpose of this study was to explore the feasibility and validity of Prospective Science Teachers' (PSTs) concept maps as authentic assessment tools in a…

This article briefly reviews the central ideas associated with the notion of systemic reform and indicates how these ideas are manifested in the draft of the National Science Education Standards. The draft is critiqued and what the critique suggests about the viability and utility of the notion of systemic reform is considered. The discussion…

The primary aim of this research project was to assist elementary classroom teachers in developing and using appropriate techniques for assessing and recording their students' achievement in science (taught as a core subject or as part of an environmental studies topic). The project was designed with the intention of providing a supportive…

Describes a video monitoring technique for detailed analysis of student use of computer-based learning programs which produces a synchronized record of computer output and student use; a study concerned with developing computer-based learning programs in chemistry which utilizes the technique; and advantages and disadvantages of the technique.…

The Science Activities Action Research Group considered problems related to using science activities in teaching/learning of science ideas, problems previously identified and described during exploratory/in-depth phases of the Learning in Science Project. Three specific tasks were formulated by the group, including: investigating wording of…

Reports on a study undertaken to validate the practicality of using the Constructivist Learning Environment Survey (Perceived Form) (CLES) in a preservice elementary science methods course. Suggestions are made to potentially revise the CLES for more accurate measures in college classrooms. (LZ)

This quantitative/qualitative evaluation of an 80-hour course integrating the SCOPE Computer Program in Mathematics and Science into the curriculum for students, grades 6-12, was conducted to: (1) provide immediate feedback to facilitate improvement of the program; (2) determine course effects; and (3) provide practitioners with an effective…

Deals with the practical assessment of the General Certificate of Secondary Education (GCSE) in Great Britain with regard to the requirements set forth in biology syllabi. Addresses the requirements of the British National Criteria for assessment of experimental skills, the assessment framework, and the principle of positive achievement. (TW)

Secondary education of students with learning and behavioral disabilities is an issue of great importance. Unlike elementary schools, secondary schools require substantially more independent functioning, assume the effective use of student planning and study skills, and often lack the classes in basic skills needed by some learners. Further, new…
