同伴互评能够促进学习者高阶认知能力的发展。文章采用认知网络分析法,以课程进程中四次作业的同伴互评评语为分析对象,从时间序列视角探索同伴互评对学习者知识建构的过程影响与差异影响,剖析出在高校课程教育中"以评促学"的作用机理。研究发现:同伴互评能有效提高学习者深层次的知识建构,帮助学习者在更高阶认知结构上进行知识构建;在同伴互评策略支持下,高、低元认知自我调节能力水平学习者与整体学习者的知识建构过程趋同,即都经历了从浅层学习到深度学习的发展过程;但是,对于高水平元认知自我调节能力组学习者而言,同伴互评在提升学习者认知结构的综合性和深层次的建构方面,有更加明显的作用。  相似文献

Within the cognitive load theory framework, we designed and compared three alternative instructional solution formats that can be derived from a common static hierarchical network representation depicting problem structure. The interactive-solution format permitted students to search in self-controlled manner for solution steps, static-solution format displayed all solutions steps, and no-solution format did not have solution steps. When we matched instructional time across the formats, in relation to the complex molarity problems rather than the dilution problems, differential transfer performance existed between the static-solution or no-solution formats and the interactive-solution format, but not between the static-solution format and no-solution format. The manner in which learners interact with the static-solution and no-solution formats depends on their level of expertise in the chemistry domain. With considerable learner expertise, provision of solution steps may be redundant incurring extraneous cognitive load. Absence of the solution steps may not have left sufficient cognitive capacity for germane cognitive load as some beginning learners lacked the prior knowledge to deduce the solution steps. Searching for solution steps presumably incurred extraneous cognitive load which interfered with learning and hence, in the interactive-solution format, it outweighed the benefit of engaging in self-regulated interaction with the content. Hence, cognitive load theory is a promising tool to predict the mental load associated with learning from the three alternative computer-based instructional formats.  相似文献

ABSTRACT

Amateur musical instrument learners are usually taught in a one-to-many learning mode owing to the cost consideration; therefore, it is difficult for the teacher to address individual students’ problems. This results in a lack of knowledge internalization. The flipped classroom enables the teacher to have more in-class time to interact with individual students. However, when the teacher guides a learner in the flipped class, the other learners usually practice on their own rather than engaging in critical thinking or reflective thinking activities. Therefore, this study uses the peer assessment strategy to increase the effectiveness of musical instrument flipped teaching. However, conventional peer assessment flipped teaching (CPA) has some disadvantages. So, we present another method in which the peer assessment is performed by online video sharing (VSPA). The VSPA method can further extend the learning time until after class. It lets teachers have more time to solve the problems of individual students. Besides, it can reduce the students’ nervousness. The experimental results showed that both of the two teaching modes can help progression, but there is no significant difference in the learning effectiveness. As for learning preference, we found that the learners preferred CPA to VSPA.  相似文献

Cognitive load measurement is an important aspect of educational research. Current cognitive load surveys differentiate between intrinsic cognitive load (resulting from the complexity of learning materials) and their extraneous cognitive load (which is increased by a demanding design). In two studies, order effects of cognitive load subscales are demonstrated. Asking learners regarding their intrinsic load first increases their responses concerning this type of load, with little effect on extraneous load ratings. This effect can be replicated even when extraneous load is intentionally induced. This finding has important implications for cognitive load research, as the order of surveys appears to bias cognitive load ratings. As most cognitive load research is conducted to find ways of reducing extraneous load, it may be reasonable to carefully consider whether and when intrinsic load items are included in studies. Generally, the results show that study participants seem to emphasize certain demands, similar to a dialogue.  相似文献

Knowledge elaboration: A cognitive load perspective   总被引:3,自引:3,他引:0  
The process of knowledge elaboration is considered from the perspective of cognitive load theory. This theory assumes that the available knowledge structures in long-term memory (LTM) are used to organize and guide cognitive processing in complex learning. Accordingly, the role of external instructional guidance in the process of knowledge elaboration could be described as providing a substitute for knowledge structures missing from LTM. Thus, the executive guidance in complex learning environments is shared between the person (based on his/her LTM knowledge structures) and another expert or instructional means. This article analyzes instructional implications of this assumption. Adaptive learning environments are suggested for tailoring knowledge elaboration processes to changing characteristics of individual learners. Means for identifying and predicting the learner's LTM-based executive guidance are proposed so that they can be utilized in the building of adaptive learning environments.  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

The Internet has recently been identified as a potential enabler of lifelong learning. Web‐based learning systems enable learners easily to access rich resources and actively participate in learning activities without time and distance limits. The main challenge in lifelong learning is providing the opportunity for discussion and collaborative knowledge construction to engage learners in acquiring and applying knowledge in the context of learning, working and collaboration. Moreover, knowledge sharing is a key component in the formation of communities of lifelong learners. Most online collaborative learning communities use Web text‐based discussion forums for knowledge sharing. However, such discussion forums are separated from the context of learning activities. Furthermore, the facilitation of beneficial dialogue through discussion forums, requires the involvement of mentors as facilitators. This study proposes an e‐book interface that enables learners easily to annotate or enter queries in a text in which questions arise, where a query context is transferred to a discussion forum. The subsequent anchors of questions are linked to a discussion forum for actuating sustained participation. A mentor finder recommends a collaborative peer based on learner knowledge level to answer the questions. Learners can also use mobile phones to access this ubiquitous discussion forum using voice/text anytime and anywhere. The experimental results showed a clear increase in the level of discussions, and most learners indicated that they benefited considerably from collaborative mentor support in an e‐book learning context through the provision of a ubiquitous discussion forum.  相似文献

多媒体学习理论是一个贯通了学习理论与教学理论的科学体系。作为学习理论的多媒体学习认知理论基于双重编码理论、工作记忆模型以及生成加工理论,解释了学习者通过加工语词与画面所呈现的材料来建构知识的学习机制,属于解释性理论;作为教学理论的多媒体教学设计理论发展出一系列教学设计应遵循的原则,为教育实践提供了具有处方性意义的行动指南,属于处方性理论。解释性的学习理论为处方性的教学理论提供了扎实可靠的科学基础。在多媒体学习研究从学习理论向教学理论转化的过程中,多媒体教学设计理论是实现跃迁的关键环节,而认知负荷理论则是理论跃迁成功的关键变量。基于认知负荷理论,梅耶提出多媒体学习认知负荷三元模型,包括必要认知加工、外来认知加工和生成性认知加工。围绕这三类认知加工,梅耶及其同事进行了大量的实验研究,最终确定了12项与多媒体学习认知理论及其前提假设保持高度逻辑一贯性的多媒体教学设计原则。这些原则都是经得起实践检验的,但教学设计人员在应用的过程中,应明确各项原则的问题情境、适用范围等边际条件。  相似文献

Learning with hands-on experiments can be supported by providing essential information virtually during lab work. Augmented reality (AR) appears especially suitable for presenting information during experimentation, as it can be used to integrate both physical and virtual lab work. Virtual information can be displayed in close spatial proximity to the correspondent components in the experimentation environment, thereby ensuring a basic design principle for multimedia instruction: the spatial contiguity principle. The latter is assumed to reduce learners' extraneous cognitive load and foster generative processing, which supports conceptual knowledge acquisition. For the present study, a tablet-based AR application has been developed to support learning from hands-on experiments in physics education. Real-time measurement data were displayed directly above the components of electric circuits, which were constructed by the learners during lab work. In a two group pretest–posttest design, we compared university students' (N = 50) perceived cognitive load and conceptual knowledge gain for both the AR-supported and a matching non-AR learning environment. Whereas participants in both conditions gave comparable ratings for cognitive load, learning gains in conceptual knowledge were only detectable for the AR-supported lab work.  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

The purpose of this study was to examine the effects of a metaphorical interface on germane cognitive load in Web-based instruction. Based on cognitive load theory, germane cognitive load is a cognitive investment for schema construction and automation. A new instrument developed in a previous study was used to measure students?? mental activities of schema construction and automation supported by structural cues in a metaphorical interface environment. Eighty participants were randomly assigned to one of two types of instructional units with the same instructional content and different interface types (i.e., non-metaphorical interface and metaphorical interface). The results indicated that germane cognitive load positively affected learning performance while there was no relationship between germane cognitive load and students?? prior knowledge. A metaphorical interface enhanced learners?? germane cognitive load and learning performance, and both germane cognitive load and prior knowledge similarly contributed to learning performance. The findings provide implications for the advancement of cognitive load theory and the practice of instructional development.  相似文献

The ability to self‐reflect is widely recognized as a desirable learner attribute that can induce deep learning. Advances in computer‐mediated communication technologies have led to intense interest in higher education in exploring the potential of digital tools, particularly digital video, for fostering self‐reflection. While there are reports pointing to the salutary effects of digital video on learners’ reflective ability, a systematic inquiry into how digital video can be utilized to promote self‐reflection in an ePortfolio context remains under‐reported. In this paper, we pose two questions: (1) Do students have the confidence to create their own digital videos for reflection and do they find this activity relevant to their learning needs?; and (2) To what extent does digital video affect the level of self‐reflection and the nature of peer feedback? Results from this small‐scale exploratory case study provide evidence in support of video use as a reflective tool in an ePortfolio context and highlight the need for considering pedagogical and technological issues that are of significance for teachers, educators and ePortfolio developers.  相似文献

Cognitive load theory has been traditionally described as involving three separate and additive types of load. Germane load is considered as a learning-relevant load complementing extraneous and intrinsic load. This article argues that, in its traditional treatment, germane load is essentially indistinguishable from intrinsic load, and therefore this concept may be redundant. Contrary to extraneous and intrinsic load, germane cognitive load was added to the cognitive load framework based on theoretical considerations rather than on specific empirical results that could not be explained without this concept. The design of corresponding learning activities always required methods and techniques external to the theory. The article suggests that the dual intrinsic/extraneous framework is sufficient and non-redundant and makes boundaries of the theory transparent. The idea of germane load might have an independent role within this framework if (as recently suggested by John Sweller) it is redefined as referring to the actual working memory resources devoted to dealing with intrinsic rather than extraneous load.  相似文献
