The present study describes the development and field testing of a simple apparatus-based diagnostic instrument (SABDI) that examines undergraduate students' understanding of the underlying physics principles that explain how simple acoustic apparatuses work. SABDI comprises 13 items. Based on previous research studies and the history of science,…

The solving of problems in biochemistry often uses concepts from multiple disciplines such as chemistry and biology. Chemical identity (CI) is a foundational concept in the field of chemistry, and the knowledge, thinking, and practices associated with CI are used to answer the following questions: "What is this substance?" and "How…

Considerable debate exists among discipline-based astronomy education researchers about how students change their perceptions in science and astronomy. The study questioned the development of astronomical models among students in institutions of higher education by examining how college students change their initial conceptual frameworks and…

Our interpretative study that was carried out in a science and engineering oriented university examined the ways students in an introductory biology course perceived their learning in the course that was substantially changed to allow student-centered learning. The instructional change was framed by the view of learning as a sociocultural activity…

Assessment in education employing web tools, also known as e-assessment, deals with the effective use of technology to support successful instruction. The aim of this study was to investigate learning outcomes and the students' attitudes to online Moodle quizzes in order to improve instructional design. The research population included 204 college…

This study examines chemistry lecturers' considerations for using open educational resources (OER) in their teaching. Recent technological developments provide innovative approaches for teaching chemistry and visualizing chemical phenomena. End users' improved ability to upload information online enables integration of various pedagogical models…

Context-based chemistry education aims to improve student interest and motivation in chemistry by connecting canonical chemistry concepts with real-world contexts. Implementation of context-based chemistry programmes began 20 years ago in an attempt to make the learning of chemistry meaningful for students. This paper reviews such programmes…

Chemical phenomena can be described using three representation modes: macro, submicro, and symbolic. The way students use and connect these modes when solving conceptual problems was studied, using a think-aloud interview protocol. The protocol was validated through interviews with six faculty members, and then applied to four graduate and six…

Describes a specially designed preparatory course in science and mathematics for relatively "unprepared" adult students in Israel. Compares the achievements of these students with the achievements of those identified as "prepared" according to their formal education and qualifications. (TW)

A two-semester basic chemistry course for nonchemistry engineering majors is described. First semester provides introductory chemistry for freshmen while second semester is "customer-oriented," based on a departmental choice of three out of six independent modules. For example, aeronautical engineering "customers" would select…

This study, an extension of previous studies, compared the views of freshmen college biology, chemistry, and physics students (N=229) with those of high school seniors (N=437), focusing on: (1) interest in different high school topics; (2) nature of high school laboratory experiences; (3) use of innovative instructional strategies in high school;…

Following the description of a college organic chemistry course involving self-study and small group classroom work, summarizes five years of teaching the course (1976-1980) to chemistry majors. (Author/SK)

Discusses the rationale for and development of an industrial chemistry program in chemistry at Ben-Gurion University of the Negev in Israel. Includes an outline of the recommended 2-year curriculum and list of courses in this industrial chemistry option leading to a master of science degree. (Author/JN)

Presents a view of future engineering education as perceived by the Technion faculty group on the basis of their own analysis and the insights gathered from workshop discussions. Contrasts basic and specialized education. Reviews the technologies and skills of the future engineer. Gives an overview of curriculum requirements. (CW)

The need to support bioinformatics training has been widely recognized by scientists, industry, and government institutions. However, the discussion of instructional methods for teaching bioinformatics is only beginning. Here we report on a systematic attempt to design two bioinformatics workshops for graduate biology students on the basis of…
