A WebQuest is an inquiry-based online learning technique. This technique has been widely adopted in K–16 education. Therefore, it is important that conditions of effective WebQuest design are defined. Through this article the author presents techniques for improving WebQuest design based on current research. More specifically, the author analyzes the WebQuest technique in terms of the principles of cognitive load theory, interactivity, accessibility, and usability and visual appearance. The author argues that several factors must be taken into consideration in order to effectively design WebQuests that will educate without impeding the learning process.  相似文献

The proliferation of broadband mobile devices, which many students bring to school with them as mobile phones, makes the widespread adoption of AR pedagogies a possibility, but pedagogical, distribution, and training models are needed to make this innovation an integrated part of education, This paper employs Social Construction of Technology (SCOT) to argue for a participatory model of scaling by key stakeholders groups (students, teachers, researchers, administrators), and demonstrates through various cases how ARIS (arisgames.org) — a free, open-source tool for educators to create and disseminate mobile AR learning experiences — may be such a model.  相似文献

This article explores how learning biological concepts can be facilitated by playing a video game that depicts interactions and processes at the subcellular level. Particularly, this article reviews the effects of a real-time strategy game that requires players to control the behavior of a virus and interact with cell structures in a way that resembles the actual behavior of biological agents. The evaluation of the video game presented here aims at showing that video games have representational advantages that facilitate the construction of dynamic mental models. Ultimately, the article shows that when video game’s characteristics come in contact with expert knowledge during game design, the game becomes an excellent medium for supporting the learning of disciplinary content related to dynamic processes. In particular, results show that students who participated in a game-based intervention aimed at teaching biology described a higher number of temporal-dependent interactions as measured by the coding of verbal protocols and drawings than students who used texts and diagrams to learn the same topic.  相似文献

Cognitive science principles should have implications for the design of effective learning environments. The self-explanation principle was chosen for the current work because it has developed significantly over the last 20 years. Early formulations hypothesized that self-explanation facilitated inference generation to supply missing information about a concept or target skill, whereas later work hypothesized that self-explanation facilitated mental-model revision (Chi, Handbook of research on conceptual change, 2000). To better understand the complex relationship between prior knowledge, cognitive processing, and changes to a learner’s representation, two classes of self-explanation prompts (gap-filling and mental-model revision) were tested in the domain of physics problem solving. Prompts designed to focus the learner on gap-filling led to greater learning and a reduction in the amount of tutoring assistance required to solve physics problems. The results are interpreted as support for the instructional fit hypothesis—the idea that the efficacy of instruction is contingent on the match between the cognitive processing that the instruction elicits, how those processes modify the underlying knowledge representations for the task, and the utility of those representations for the task or problem.  相似文献

We present mathematical models for the evolution over time of the proportion of minorities in an academic department or similarly selected group of constant size. Using the models, we analyze both the steady-state and time-dependent behavior of the proportion of minorities, and also obtain a means of evaluating the effectiveness of a department's hiring history. We derive a number of surprising results with importance to institutional hiring policy and affirmative action; and we also present methods, suggested by the model and its behavior, to improve departmental hiring practices.  相似文献

During medium to large-scale emergency events such as fires or earthquakes, emergency response teams must be deployed to the location of the event in a timely fashion. Information gathered from 9-1-1 call makers is useful for this, but is not always accurate. In this paper, we show how the space–time permutation scan statistic can be used to detect the presence and location of such events by monitoring the overall spatiotemporal pattern of 9-1-1 emergency calls instead. In an analysis of collected 9-1-1 call data, top detected clusters were found to correlate with emergency events as reported on the news, showing the algorithm's usefulness for automatically estimating their location and temporal extent. We show how the detection procedure works in cases where the emergency event generates a small but statistically significant increase in the number of 9-1-1 calls, as well as cases where events must be detected against a large background activity of 9-1-1 calls. We discuss the possible adoption of the proposed algorithm within the next generation digital government framework.  相似文献

This paper discusses the possibility of providing effective counseling for speech-language impaired clients who, due to a communication breakdown, find themselves in a particularly serious predicament marked by isolation and dependency. Its purpose is to highlight the special needs of these clients and to suggest therapeutic strategies suitable for meeting their needs. To promote the idea of an integrative approach to counseling, it will be shown that the counselor, as the key figure in rehabilitation, can coordinate the work of several professionals and contribute in a unique way to the well-being of these individuals.  相似文献

Arguments are put forward in this paper that classroom word problem solving is more-and also less-than the urgent analysis of a factual structure, in the sense that it is essentially a species of a social-cognitive activity. Word-or story-problems, presented in classroom contexts, represent textual and pragmatic patterms of a certain grammaticality. To present a problem verbally to a student means to organize a fact in some way for the attention of a problem solver. There is not only the structure of the problem text itself by which situations are denoted, but there is also the stimulative nature of the social-pragmatic context which shapes the student's textbook-problem solving behavior over a long period of time.The present paper discusses the results of several studies showing, for example, that subject matter related attitudes towards a problem frequently do not play an important part in the problem solving efforts; that students often solve problems correctly without understanding them; and that false contextual expectations can lead to abstruse errors of understanding and to peculiar solution attempts.The studies indicate that students can become sensitive and skilful in perceiving and capitalizing on subtle textual and contextual signs pointing to the solution and anticipating its pattern. It seems that usual textbook problems let students get accustomed to certain courses of processing where a simple fact, like whether an equation works out evenly or does not, can stop the process or push it further. It is argued that the deeper reason for the observed textual and contextual influences on understanding and problem solving lies in a fundamental weakness of the student's epistemic control behavior. The psychological and instructional significance of the studies is discussed.  相似文献
