Systems thinking and abstract thinking are important skills for engineers in general and hardware and software engineers in particular. Systems thinking emphasises the interdependence of system components and their synergy. Abstract thinking permits one to focus on the significant details of the current perspective, while temporarily neglecting…

In an era in which information is rapidly growing and changing, it is very important to teach with the goal of students' engagement in life-long learning in mind. This can partially be achieved by developing transferable thinking skills. In our previous paper--Part I, we conducted a review of the transfer literature and suggested a three-attribute…

This paper describes a study conducted in the context of chemistry education reforms in Israel. The study examined a new biochemistry learning unit that was developed to promote in-depth understanding of 3D structures and functions of proteins and nucleic acids. Our goal was to examine whether, and to what extent teaching and learning via…

A new learning unit in chemistry, "Case-based Computerized Laboratories" (CCL) and Computerized Molecular Modeling" (CMM) was developed at the Technion. The CCL and CMM curriculum integrates computerized desktop experiments and molecular modeling with an emphasis on scientific inquiry and case studies. Our research aimed at…

The intended, implemented, and actually achieved chemistry curricula were studied in 26 Israeli high schools (514 students) through review of the planned curriculum, questionnaires, and test results. In spite of the intended and implemented curricula's goals, actual achievement is low, particularly in the area of application of principles. (SLD)

The use and analysis of student generated propositions linking two scientific concepts (photosynthesis and respiration) were examined before and after the study of photosynthesis. A proposition-generating task (PGT) was used as a diagnostic tool to indicate student misconceptions and partial understandings. Focus was on determining: how the nature…

This article deals with 12th-grade students' conceptions of a mathematical definition. Their conceptions of a definition were revealed through individual and group activities in which they were asked to consider a number of possible definitions of four mathematical concepts: two geometric and two analytic. Data consisted of written responses to…

There have been few discoveries in geology more important than "deep time"--the understanding that the universe has existed for countless millennia, such that man's existence is confined to the last milliseconds of the metaphorical geological clock. The influence of deep time is felt in a variety of sciences including geology, cosmology,…

The performance of 254 Israeli twelfth graders on multiple-choice tests with positive or negative item stems was studied. For items requiring low cognitive reasoning, performance does not differ, but, for items requiring high cognitive reasoning, the negative mode is more difficult. Implications for test construction are discussed. (SLD)

Project-based learning (PBL) that has authenticity in the pupils' world enables the teaching of science and technology to pupils from a variety of backgrounds. PBL has the potential to enable pupils to research, plan, design, and reflect on the creation of technological projects (Doppelt, 2000). Engineering education, which is common in Israel,…

In recent years, the science teaching community and curriculum developers have emphasised the importance of teaching inquiry and teaching science as inquiry. One way of developing learners' skills for planning and carrying out scientific research is by allowing them to perform independent research, guided by a teacher. It was recently discovered…
