认知悖论的研究具有重要的哲学和逻辑意义。从哲学基本问题的视角去分析,对认知悖论的理解就可以豁然开朗。以＂意料之外的鸡蛋＂、＂意料之外的老虎＂和＂刽子手悖论＂三个悖论为例加以分析,可以发现其中的错误都根源于混淆了思维和存在,以及与思维和存在的区分相联系的两种＂知道＂（＂后知＂和＂预知＂）和两种＂真＂（＂反映真＂和＂预期真＂）的概念。 相似文献

教学视频因其多通道展现教学内容的特性而成为数字化学习资源的首选形态。线索作为教学视频中的重要引导性教学设计手段,探究其类型及学习者先前知识经验对学习效果的交互影响,有益于优化教学视频的设计策略。基于学习者先前知识经验水平(高水平和低水平)和线索类型(言语线索和视觉线索)两个维度,运用眼动追踪技术和认知负荷、学习满意度、学习效果等测量工具,通过实验考察二者对学习的影响及其内在机制后发现:学习者先前知识经验水平对认知负荷的影响显著;线索类型对学习满意度的影响显著,且线索类型与学习者先前知识经验水平在学习满意度上的交互效应显著;学习者先前知识经验水平对学习效果的影响显著,且线索类型与学习者先前知识经验水平在迁移测验成绩上的交互效应显著。实验结果表明,线索类型与学习者先前知识经验水平对学习满意度和学习效果存在明显的交互作用,即只有低知识经验水平学习者在学习含有视觉线索的教学视频后,学习满意度与学习效果才有显著提升。这可能是由于该类学习者在信息选择时存在困难,视觉线索可以帮助其提高信息搜索效率,而言语线索却会使其认知负荷超载。 相似文献

Informed by the cognitive theory of multimedia learning, this study examined the effects of three multimedia design principles on undergraduate students' learning outcomes and perceived learning difficulty in the context of learning entomology from an educational video. These principles included segmenting the video into smaller units, signalling to direct students' attention to relevant information, and weeding to remove any non-essential content (SSW). It was hypothesized that the SSW treatment would decrease perceived learning difficulty and facilitate the transfer of knowledge and the structural knowledge acquisition. Results of the study demonstrate that participants in the SSW group outperformed the non-SSW group on the tests of knowledge transfer and structural knowledge acquisition and reported lower levels of learning difficulty. These findings support the use of SSW to help novice learners organize and integrate knowledge from complex, dynamic audio-visual media like video. 相似文献

This paper explores the link between teacher research and whole school change. As the authors investigated three US schools described as having close ties between teacher research and school culture, they discovered that moving teacher research out of individual classrooms and into entire schools is astonishingly difficult work filled with paradox and seeming-impossibilities. They offer six key paradoxes and conclude that when these paradoxes are managed, teacher research has the potential to affect both the culture of schools and the experience of teaching and learning for students and teachers alike. 相似文献

After impasses, the adjustment strategies learners can use in simulations differ from the ones that are available in real-life situations. An open question is whether learners with different levels of prior knowledge use different strategies to adjust their behavior and whether the chosen adjustment strategy helps their learning. In addition, it is unclear whether adjustment strategies are stable throughout the learning process. To answer these questions, we conducted two studies that both used a medical education simulation in which a learner collaborated with an agent-based radiologist to diagnose patients. In study 1 we found that the adjustment strategy of further evidence generation was only helpful for learners with intermediate prior knowledge whereas the likelihood of an accurate diagnosis descreased for learners with low or high prior knoweledge. In Study 2, we found three relatively stable clusters: reflective learners, variable learners, and evidence generators, thus offering the potential for adaptive scaffolding. 相似文献

Conceptual bases of intervention and policy are often subject to paradoxical dilemmas, such as the need for a coherent program model versus recognition of the diversity of a target population. This article aims to identify underlying paradoxical bases for expansion and replication of early childhood care and education programs, and to suggest potential resolutions of these paradoxes. Clarification of such paradoxes may provide guidance for the many decision points which arise in processes of identifying, expanding, and replicating early childhood programs based on evidence of quality or success. First, a brief history of early childhood care and education in the U.S. from the viewpoint of expansion and replication is presented. A five-fold typology of expansion and replication processes is proposed: staged replication, franchised replication, multi-site demonstrations, mandated replication, and government-supported private sector expansion. Second, paradoxes associated with the process of replication are considered, such as: (1) the “can it work” versus “does it work” paradox; (2) the fidelity versus local cultural relevance paradox; (3) the replication versus addition paradox; (4) the replication versus program improvement paradox; and (5) the representativeness versus feasibility paradox. In a concluding section, recommendations for funders, policy makers, and evaluators are made regarding next steps in expansion and replication of early childhood care and education programs. 相似文献

Providing prompts to induce focused processing of the central contents of instructional explanations is a promising instructional means to support novice learners in learning from instructional explanations. However, within research on the expertise reversal effect it has been shown that instructional means that are beneficial for novices can be detrimental for learners with more expertise if the instructional means provide guidance that overlaps with the internal guidance provided by the prior knowledge of learners with more expertise. Under such circumstances, prompts to induce focused processing might even be detrimental for learners with expertise whose prior knowledge already provides internal guidance to learn from explanations. On this basis, we aimed at experimentally varying expertise by developing prior knowledge. Specifically, we used a preparation intervention with contrasting cases to enhance learners’ prior knowledge (expertise). Against this background, we tested 71 university students in a 2 × 2 factorial experimental design: (a) Factor of expertise. Working with contrasting cases to develop prior knowledge and expertise to provide internal guidance to learn from instructional explanations (with vs. without), (b) Factor of prompts. Prompts to induce focused processing of the explanations (with vs. without). The results showed that prompts to induce focused processing fostered conceptual knowledge for novice learners whereas prompts hindered the acquisition of conceptual knowledge for learners with expertise that was developed by working with contrasting cases beforehand. Moreover, measures of subjective cognitive load and learning processes suggest that the instructional guidance provided by prompts compensated for the low internal guidance of novice learners and overlapped with the internal guidance of learners with expertise. 相似文献

Acquiring complex conceptual knowledge requires learners to self-regulate their learning by planning, monitoring, and adjusting the process but they find it difficult to do so. In one experiment, we examined whether learners need broad systems of support for self-regulation or whether they are also able to learn with more economical support configurations. Eighty-six undergraduate students with little prior domain knowledge learned plate tectonics from a multimedia presentation involving animation with concurrent narration and support in one of four forms: minimal support, two variants of intermediate support, or extensive support. After the presentation, participants solved retention and transfer tests. The results revealed that participants receiving the broadest system of support outperformed those in the other conditions, which did not differ from one another. This means that it is so difficult for learners to self-regulate learning that they need considerable support if they are to learn complex conceptual knowledge. 相似文献

Recent curriculum reform promotes core competencies such as desired ‘content knowledge’ and ‘communication’ for meaningful
learning in biology. Understanding in biology is demonstrated when pupils can apply acquired knowledge to new tasks. This
process requires the transfer of knowledge and the subordinate process of translation across external representations. This
study sought ten experts’ views on the role of transfer and translation processes in biology learning. Qualitative analysis
of the responses revealed six expert themes surrounding the potential challenges that learners face, and the required cognitive
abilities for transfer and translation processes. Consultation with relevant curriculum documents identified four types of
biological knowledge that students are required to develop at the secondary level. The expert themes and the knowledge types
exposed were used to determine how pupils might acquire and apply these four types of biological knowledge during learning.
Based on the findings, we argue that teaching for understanding in biology necessitates fostering ‘horizontal’ and ‘vertical’
transfer (and translation) processes within learners through the integration of knowledge at different levels of biological
organization. 相似文献

This study examined the effectiveness of a computer-based environment employing three example-based instructional procedures (example–problem, problem–example, and fading) to teach series and parallel electrical circuit analysis to learners classified by two levels of prior knowledge (low and high). Although no differences between the instructional procedures were observed, low prior knowledge learners benefited most from traditional example–problem pairs while their high prior knowledge counterparts benefited most from problem–example pairs. Overall, this study provides empirical support for the expertise reversal effect, which suggests that the effectiveness of certain instruction procedures in example-based learning environments depends upon the learners' level of prior knowledge. 相似文献

Learning from Worked-Out Examples: The Effects of Example Variability and Elicited Self-Explanations
《Contemporary educational psychology》1998,23(1):90-108
It was investigated to what extent example variability and the elicitation of sophisticated self-explanations foster the acquisition of transferable knowledge by learning from worked-out examples. In addition, it was asked whether the effects of these factors are moderated by the learners' levels of prior topic knowledge. To this end, we had 56 apprentices from a bank learn calculation of compound interest and real interest. They were randomly assigned to the four conditions of a 2 × 2-factorial design (factor 1: uniform vs. multiple examples; factor 2: spontaneous vs. elicited self-explanations). The learning results were measured by a post-test comprising near-transfer problems and far-transfer problems. It was found that the acquisition of transferable knowledge can be supported by eliciting self-explanations. In the case of near transfer, especially learners with low levels of prior topic knowledge profited from the elicitation procedure. On the whole, the findings underline the “causal” relevance of the quality of self-explanations for knowledge acquisition by learning from worked-out examples. The assumption that multiple examples foster transfer performance, at least when sophisticated self-explanations are elicited, was not supported. 相似文献

Multimedia learning environments combine multiple forms of representations like texts, static and animated pictures or graphs. Knowledge acquisition from multiple representations requires that the learner create referential connections between corresponding elements and corresponding structures in different representations. As this process is usually difficult, learners frequently fail to construct coherent mental representations and, thus, do not sufficiently understand the subject matter. This paper analyzes the effects of different kinds of instructional help on the process of coherence formation from multiple representations by learners with different prior knowledge. Three groups of university students with different domain-specific knowledge had to learn a complex subject matter from chemistry using six different forms of representation. In addition, a first group received directive help for coherence formation. A second group received non-directive help, and a third group received no instructional help. Results indicate that directive help is effective for recall performance because of its summarizing and repeating function. Furthermore, learners with different levels of prior knowledge show different reactions when help is given. For learners with insufficient prior knowledge help is not helpful or, in case of recall performance, even harmful. Learners with a medium level of prior knowledge can increase especially their comprehension performance when help is offered, whereas learners with too much prior knowledge seem not to be affected by help. 相似文献

The purpose of this study was to examine the effects of the type of exploratory strategy and level of prior knowledge on middle school students’ performance and motivation in learning chemical formulas via a 3D role-playing game (RPG). Two types of exploratory strategies—RPG exploratory with worked-example and RPG exploratory without worked-example—and two levels of prior knowledge—high prior knowledge and low prior knowledge—were examined in the study. The 5E Instructional Model was employed as a learning framework in the RPG game design of The Alchemist’s Fort. One hundred and fifteen eighth-grade students from a Taiwanese school voluntarily participated in the 3-week experiment. The results indicate that (1) significant worked-example effect was revealed on knowledge comprehension and marginal worked-example effect occurred on knowledge application; (2) regardless of the type of exploratory strategy employed, learners showed mild positive motivation toward learning chemistry via a 3D RPG game; (3) higher prior-knowledge learners outperformed their lower prior-knowledge peers on performance measures; and (4) high prior-knowledge learners showed a higher degree of motivation in self-efficacy and science learning value than did the low prior-knowledge learners; however, lower prior-knowledge learners revealed higher learning environment stimulation than did their high prior-knowledge peers. 相似文献

Subgoal learning, a technique used to break down problem solving into manageable pieces, has been used to promote retention and transfer in procedural domains, such as programming. The primary method of learning subgoals has been passive, and passive learning methods are typically less effective than constructive methods. To promote constructive methods of learning subgoals, we prompted learners to self-explain the subgoals of a problem-solving procedure. Self-explanation asks learners to make sense of new information based on prior knowledge and logical reasoning. Novices’ self-explanation is typically more effective when they receive guidance, because it helps them to focus on relevant information. In the present experimental study, the types of guidance that students received while self-explaining determined whether the constructive learning method was more effective than the passive method. Participants assigned to the constructive learning method performed best when they either received hints about the subgoals or received correct explanations as feedback, but not when they received both. These findings suggest that constructive learning of subgoals can further improve the benefits of subgoal learning when students receive only guidance that complements their construction of knowledge. This nuance is important for educators who engage their students in constructive learning and self-explanation. 相似文献

Asynchronous distance education can replicate traditional face-to-face training or education; but, why should it do so? Asynchronous distance education provides an opportunity to create meaningful learning which is not feasible in a traditional classroom, provided that communities of learners that encourage knowledge building and social reinforcement are specifically created. This article describes the need for learning communities within the context of asynchronous distance education. Asynchronous learning communities are specifically relevant for training environments, given the need for instant and constant training with employees who are located in an ever-expanding national and international workplace. Specifically, three types of communities are described: academic, intellectual and interpersonal. 相似文献

Inquiry learning is an educational approach in which learners actively construct knowledge and in which performing investigations and conducting experiments is central. To support learners in designing informative experiments we created a scaffold, the Experiment Design Tool (EDT), that provided learners with a step-by-step structure to select variables and to assign values to these variables, together with offering built-in heuristics for experiment design. To further structure the students’ approach, the EDT was offered within a set of detailed research questions which again were grouped under a set of broader research questions. Learning results for learners who worked with the EDT were compared to results for learners in two control conditions. In the first control condition, learners received only the detailed research questions and not the EDT; in the second control condition, learners received only the limited set of general research questions. In all conditions, learners conducted their experiments in an online learning environment about the physics topic of Archimedes’ principle. Conceptual knowledge was measured before and after the intervention using parallel forms of a knowledge test. Overall results showed significant learning gains in all three conditions, but no significant differences between conditions. However, learners who started with low prior knowledge showed a significantly higher learning gain in the EDT condition than in the two control conditions. This result indicates that the effect of providing learners with scaffolds does not follow a “one-size-fits-all” principle, but may depend on specific learner characteristics, such as prior knowledge. 相似文献

Adults who enrol in higher education institutions (HEIs) often have contributions that could serve in enhancing the planning and implementation of their programmes. Importantly, while terms such as active learner engagement and knowledge co-creation dominate adult learning discussions, there are unanswered questions pertaining to how adult learners negotiate co-ownership of their learning. The current empirical study explores the relevant factors that could enhance adult learners’ involvement in negotiating co-ownership of learning in a higher education setting. A mixed method of gathering and analysing data from adult learners (n?=?200) was followed. While structural equation modelling (SEM) served as the quantitative data analysis method, codes, categories and themes developed from the focus group discussions and interviews were used to analyse the qualitative data. The study revealed that negotiating co-ownership of learning among adult learners in HEIs is influenced by the level of engagement and adult learners’ acquisition of relevant core knowledge and skills. The authors discuss the implications of the results by reflecting on the pluses of negotiating co-ownership of learning at the institutional and classroom levels while also showing how the lack of these provisions could hinder effective learning among adult learners. 相似文献

Theories on learning with Multiple External Representations (MER) claim that low prior knowledge learners in science have difficulties using MER, which are seen as necessary to achieve a conceptual understanding. In two experiments, we analyze the mechanisms underlying the learning of chemistry with MER. Our first experiment focuses on how MER can support learning. We found no difference in learning gains of conceptual understanding, regardless of the format (whether MER were provided or not). It is concluded that chemical MER on themself cannot be seen as learning aids. The second experiment compares three types of instructional aids (prompts, prompts with an answer, and note-taking) to determine which types of aids enhance learning with MER. Contrary to the findings of Seufert (Learn Instr 13:227?C237, 2003), path-analysis suggests that the lowest prior knowledge group benefits the most from instructional aids such as prompts and note-taking. These aids guide learners?? attention towards one specific representational format (symbols), while other formats (submicroscopic representations) receive less attention. 相似文献
