The use of the phrase 'the public understanding of science' has been under attack for some time because of its incompatibility with modern theories of learning. In an attempt to find a more acceptable model, interviews were conducted at Questacon, the Australian National Science and Technology Centre, with visitors of a wide range of ages who had used the interactive exhibits there. The study showed that, when using an exhibit, a visitor has a reminding of a similar experience that forms the basis for interpretating the exhibit. An individual's existing 'personal awareness of science and technology' (PAST) draws on this prior experience to produce an understanding of the exhibit and, to some extent, an understanding of the underlying scientific model. A model for PAST embracing these factors is proposed and is used to interpret the learning resulting from interaction with such exhibits and other kinds of science-based experience. 相似文献

Abstract This study investigates the effects on learning‐disabled students of embedding a drill and practice task within an arcade game‐like context. We identified 30 learning‐disabled and 30 nondisabled students who had conceptual understanding of addition but had not achieved automaticity in addition facts. We trained students on either a drill‐and‐practice game or an unadorned, straightforward drill (i.e., “plain vanilla") program. We assessed automaticity in three modes of responding—oral, computer keyboard, and written response. There was a significant interaction effect indicating that the learning‐disabled students were relatively disadvantaged by repeated practice in the game format. We infer learning‐disabled students' lower performance is attributed to attentional difficulties, particularly selective attention problems, when potentially distracting elements of a game environment are present. 相似文献

One of the characteristics of curriculum development in recent years has been an increased emphasis on using contexts and applications as a means of developing scientific understanding. Yet relatively little has been done to compare the effects of learning on context‐based approaches to science teaching with more traditional approaches. This study compares the performance on a range of diagnostic questions of pupils following both a context‐based approach and a more traditional approach to high school chemistry. The study shows that there is little difference in levels of understanding, but that there appear to be some benefits associated with a context‐based approach in terms of stimulating pupils’ interest in science. 相似文献

Intrinsic motivation has multiple definitions. Introductory teacher education courses must alert prospective teachers to the exceptional qualities of non‐conforming students who lack the benefit of being teacher pleasers. Teacher trainers must ensure that pre‐teachers are aware of the multiple definitions of intrinsic motivation prior to a request that they observe, listen, and analyze intrinsically motivated students. Without a complete understanding of the characteristics of gifted students and the types of behaviors they sometimes exhibit within the classroom, many gifted students will be unrecognized and underserved. With services to gifted students tied to their identification, it becomes important for classroom teachers to be able to recognize that the potential for gifted behavior often extends far beyond the ability to contribute efficiently and effectively. Pre‐service teachers must also recognize that intrinsically motivated students sometimes view their initial attempts as work in progress and remain skeptical and critical of their accomplishments. 相似文献

Understanding differences in perceptions of self‐concept and social support among special populations of gifted learners is critical to planning appropriate services for them. The present study investigated these differences among intellectually gifted students of junior high age who were participating in full time intensive programs for the gifted. Specifically, differences as a function of gender, ethnicity, and socio‐economic class were examined. Findings indicated some differences based on ethnicity and gender, but most differences were observed between lower and higher socio‐economic groups, particularly in the areas of social support and social and behavioral self‐concept. Implications from the study would suggest attention to these dimensions in program planning. 相似文献

Abstract Programming is an activity through which students can learn about other domains, but the difficulty of programming diminishes its usefulness as a learning activity. One approach to facilitate the use of programming for learning is to view programming as a skill like those taught through apprenticeships, and to use the apprenticeship concept of scaffolding to facilitate doing and learning through programming. Scaffolding means providing modifiable support (through fading) that communicates process, coaches, and elicits articulation. Software‐realized scaffolding embeds scaffolding in a computer‐based environment. Emile implements software‐realized scaffolding to facilitate student learning of physics by facilitating students building computer‐based models and simulations. In this article, I present Emile's features as examples of software‐realized scaffolding, and I present the results of an evaluation of Emile's effectiveness. Students were able to use Emile to create fairly sophisticated programs and gained a qualitative understanding of kinematics in the process. 相似文献

Abstract Teachers used a nonexclusionary time‐out package to treat inappropriate social behaviors that interfered with instructional tasks in four classrooms of preschool children, each containing an average of 16 students. We yoked classrooms on pretreatment scores of target behaviors and randomly assigned them to a time‐out ribbon plus praise or control condition. Students in the treatment condition wore wristbands with attached smiling face stickers and received praise from teachers for taking turns talking and remaining seated during group activities. Contingent on disruptive behavior, teachers removed the wristbands signaling a three‐minute time‐out period in which teachers restricted praise and attention but ongoing participation in activities continued. Multiple measures of treatment outcome were analyzed via MANCOVA and ANCOVAs. Behavior improved on direct observations of target behavior, the Preschool Behavior Questionnaire (PBQ) and items on a semantic differential, but not the Matson Evaluation of Social Skills with Youngsters. Treatment acceptability also supported treatment effects. We discuss implications of these results. 相似文献

The study reports an investigation into pupils’ understanding of biological and chemical terms, over the age range of 12‐18 years. The results indicate three main features: (1) knowledge is relatively short‐lived; (2) there is a lack of language precision; (3) little interaction exists between the various science subjects and between science and technology. The educational implications of these findings are explored and appropriate recommendations are made. 相似文献
