摘要:

AbstractThis paper argues that science's reputation as a ‘hard’ subject can be attributed to four intrinsic features of science and/or learners: that science knowledge provides, for many learners, insufficient ‘pay off’ for the effort involved in understanding; that learning science involves reconstructions of meaning; that the tension between science as consensually agreed knowledge and science as enquiry is confusing and eventually alienating for many learners; and because science is abstract. The reasons for a link between abstraction and difficulty are briefly explored. It is suggested that certain extrinsic features of science education, resulting from choices by science educators, exacerbate these intrinsic diffi

摘要:

AbstractThe difficulties of learning science are related to the nature of science itself and to the methods by which science is customarily taught without regard to what is known about children's learning. An information processing model is proposed to guide thinking and research in this area.

摘要:

AbstractPhysics education should take the chance to link research about students' alternative frameworks and new teaching strategies with the use of modern information technology tools. The article shows how iconic model building software like STELLA can be used to help students gain a deeper qualitative conceptual understanding.

摘要:

AbstractVideodisc technology allows the marriage of a uniquely versatile visual medium with interactive computer‐assisted learning packages and the combination can provide a very powerful educational resource. This review paper explores the teaching and learning potential of interactive video (IV), with reference to science courses, and describes some of the programmes currently in us

摘要:

AbstractThis paper describes the use of two types of physical sensor which enable the microcomputer to be used as a measuring instrument for practical experiments on motion. The systems enable a change of emphasis away from the routine activity of collecting results towards the use of interpreting skills, and are valuable for an investigative style of working in which pupils take a central role in planning and shaping their activity.

摘要:

AbstractWe outline a methodology for confronting students with the inconsistencies entailed by their own beliefs. We illustrate this with reference to one particular physics subdomain which stresses an understanding of process (how things are made to happen): thedynamicsdomain.The aspects of the methodology described are: the construction of a variety of situations which are expected to cause a student some conceptual difficulty; the predictions made by the student prior to modelling; and the observations of the student's attempts to model the situation. We use a case study to illustrate the approach.

摘要:

AbstractComputer‐based tutoring of visual concepts is a largely unexplored area. The ability to classify images, to identify features and to describe abnormalities is a necessary part of training in many professions, such as radiology, anatomy, botany and geology. To a lesser level it is important for developing everyday skills such as identifying birds, trees, rocks, and flowers. The aim of this paper is to show how computers might be used in visual concept teaching, to store and display large stocks of exemplar images, to carry out a tutorial dialogue with the learner, and to provide learning aids such as concept maps, feature spaces, and structural models. The paper describes well‐established methods for teaching visual concepts and indicates how computers can supplement the human teacher in tutoring students with differing levels of expert

摘要:

AbstractIt is now widely accepted that the cost of computers means that work around them will usually be in group's work. Hence, the question is raised of whether the group context should be explicitly recognized in the software design. The present paper outlines a study which was intended to contribute to an answer. The study addressed the consequences of exchanging ideas while making joint decisions about the paths followed by falling objects. Based on results from 12–15‐year‐old pupils who responded to computer‐presented problems, the study indicates that benefits are to be gained, but that constraints additional to joint decision making may be necessary for optimal o
