The concreteness of training materials influences learning and—perhaps more importantly—transfer. Building on prior research finding abstract representations best facilitated transfer to a game task, we conducted a similar study using training figures varying in concreteness but directly assessed transfer to modular arithmetic problems. Training figures: (a) were purely abstract, (b) were abstract but with features relevant to the transfer task, or (c) included additional concrete-relevant features. We hypothesized that concreteness—or number of relevant features—would be positively correlated with learning and transfer—especially among younger and/or lower-ability students. Although there was no overall difference in initial learning, the concrete-relevant and abstract-relevant features independently facilitated near-transfer, where concrete-relevant features supported lower-reasoning students. For far-transfer, eighth-graders benefited from the abstract-relevant features, whereas sixth-graders required additional concrete-relevant features. These findings suggest that concreteness interacts with learner and task characteristics to produce learning and transfer outcomes. 相似文献

教师的描述性手势作为教学视频中常见的一种社会线索,已有研究对其效果的结论并不一致,这可能与学习者采用的手势学习策略及其自身的空间能力有关。然而,关于不同手势学习策略对视频学习的影响学界尚存在分歧,也缺乏对注意分配及主观学习感受等方面的关注,且学习者空间能力在其中发挥的作用仍不明确。为此,借助眼动追踪技术,采用不同手势学习策略(无手势、观察手势、模仿手势)与高低空间能力的3×2混合设计的实验发现:(1)与观看无手势视频相比,学习者在观看含教师手势的视频时会将更多的注意力分配给教师区,并取得更好的学习效果和学习效率;(2)与仅观看视频(无手势、观察手势)相比,模仿手势策略除能更好地引导学习者注意分配外,在提升其即时迁移成绩、延迟成绩及学习满意度方面均具有显著优势;(3)学习者空间能力可调节手势学习策略对迁移学习效果的影响,即模仿手势可有效提高低空间能力学习者的即时迁移成绩,但对高空间能力学习者无影响。以上结论可为教学视频设计及视频学习策略的选择提供有效指导。 相似文献

This paper comments on the expanded repertoire of techniques, conceptual frameworks, and perspectives developed to study the phenomena of gesture, bodily action and other modalities as related to thinking, learning, acting, and speaking. Certain broad issues are considered, including (1) the distinction between “contextual” generalization of instances across context (of virtually any kind—numeric, situational, etc.) and the generalization of structured actions on symbols, (2) fundamental distinctions between the use of semiotic means to describe specific situations versus semiosis serving the process of generalization, and (3) the challenges of building generalizable research findings at such an early stage in infrastructure building. 相似文献

手势交互虚拟实验对学习体验的影响机制 总被引:1,自引:0,他引:1
手势交互作为一种理想的虚拟现实交互技术,其在虚拟实验中的应用能够很好地满足学习者多样化的交互需求并提升交互体验。然而,当前关于手势交互虚拟实验的研究大多聚焦于提高手势识别的准确率、设计开发不同领域的虚拟实验应用等方面,而对学习者在虚拟实验中的学习体验并未进行深入地研究。为了探索手势交互虚拟实验对学习者学习体验的影响机制,利用设计开发的基于Leap Motion的\"计算机组成原理\"虚拟实验,采用混合研究范式对学习者的沉浸感、学习动机和态度分别进行了测量与分析。结果表明:在手势交互虚拟实验中,学习动机作为中间因素会影响学习者的学习体验;身临其境的感觉和自然丰富的交互体验能够有效增强学习者的物理沉浸,进而提高学习者的学习动机,改善学习者的情感体验并增强其使用意愿,由此来促进学习者学习体验的提升。从改进实践的层面来看,未来应合理设计交互手势,创设高度沉浸的实验环境,优化虚拟实验任务设计,注重对学习反思的引导,以不断提升学习者在心理沉浸和学习效果方面的表现。 相似文献

In the recent decade, a number of literature reviews were conducted to examine the effectiveness of learning games. However, prior reviews typically focused on providing a synopsis of the overall research trends and the games’ impact on cognitive and non-cognitive learning, without providing critical and contextual information of learning-gameplay integration or the game design features. The current review focuses on recent empirical studies that implement learning games for K-12 mathematics education during the time period of 2008–2021 via a systematic search of the databases. Forty-three papers were identified as the result of a three-stage data extraction process. We identified the trends of implementing learning games in mathematics education and the ways to designing and integrating math content in gameplay. We propose that more research is needed to examine the design and use of learning games for math learning in K-12 settings. Recommendations for future game-based learning design and research are presented. 相似文献

Starting from a brief analysis of adaptive competence in mathematics, this article describes a series of research-based characteristics of the kind of learning processes that should be elicited in students to facilitate and support in them the progressive acquisition of such competence. Four major characteristics are discussed in some detail: learning is constructive, self-regulated, situated or contextual, and collaborative. A rather new approach to transfer of learning is then presented in which transfer is conceived as the preparation for future learning. Throughout the article it is argued that, notwithstanding the progress made in research on learning from instruction, numerous and complex issues and problems remain for continued inquiry. 相似文献

This study quantifies a year's worth of mathematics learning in South Africa (0.3 standard deviations) and uses this measure to develop empirically calibrated learning trajectories. Two main findings are (1) only the top 16% of South African Grade 3 children are performing at an appropriate Grade 3 level. (2) The learning gap between the poorest 60% of students and the wealthiest 20% of students is approximately three Grade-levels in Grade 3, growing to four Grade-levels by Grade 9. The paper concludes by arguing that the later in life we attempt to repair early learning deficits in mathematics, the costlier the remediation becomes. 相似文献

This article addresses the issue of the plurality of theories and perspectives in education research, and introduces postperspectival theory as a means to work with this plurality. Three pieces of research are discussed, all focusing on children’s learning of numbers, one taking a cognitivist perspective, the other two a more sociocultural perspective. Drawing on poststructuralist theory, the article addresses questions of how we make sense of research from multiple perspectives – in particular, how researchers might respond to apparent contradictions that arise when working across perspectives. A proposal for a means of working towards a synthesis of theory, using the example of children’s learning of number, is proposed. An argument is made that a postperspectival approach is first of all possible, and secondly an important tool in the construction in the development and application of educational theory. 相似文献

Considerable evidence indicates that student motivation and use of learning strategies are related. There is insufficient understanding, however, about their reciprocal effects—whether motivation affects strategy use, the converse, or whether the effects are bidirectional—and which components of motivation and strategies are involved. A two-wave longitudinal design was used to examine this issue among 9th grade students (N = 306) enrolled in high school mathematics classes during an academic term. A cross-lagged structural model found that students’ self-efficacy in mathematics and value predicted their reported use of learning strategies. There was no evidence, however, that learning strategy use predicted motivation and, thus, support for unidirectional effect of motivation during that time interval. Implications for models of self-regulated learning and instruction are discussed. 相似文献

This article summarizes findings from a 3‐year study of 35 economically disadvantaged, ethnically diverse, academically talented high school students who either achieved or underachieved in their urban high school. In particular, the resilience of these two groups of high ability students is explored. Comparative case study and ethnographic methods were used to examine the ways in which some academically talented students develop and/or employ strategies associated with resilience to achieve at high levels. Both risk factors and protective factors are examined to explore participants’ pathways toward either positive or negative outcomes. The results of this study suggest that some protective factors helped some academically talented students to achieve at high levels. The protective factors include supportive adults; friendships with other achieving students; opportunity to take honors and advanced classes; participation in multiple extracurricular activities both after school and during the summer; the development of a strong belief in self; and ways to cope with the negative aspects of their school and urban environment; and in some cases, their family lives. Other protective factors include students’ relationships with supportive adults and their previous participation in a gifted and talented program. Students who underachieved had specific risk factors, such as having older siblings who dropped out of school or became involved in drugs and/or alcohol. They also appeared to have developed fewer protective factors. The combination of the presence of risk factors and the absence of protective factors may ha ve impeded the ability of some underachieving students to achieve at higher levels. 相似文献

Analysis of the reflections of student-teachers of mathematics when working with learning portfolios in Spanish university classrooms 总被引:1,自引:0,他引:1
Research in teacher-training counsels that reflection should be fostered in order to prepare capable professionals for educational practice. For this reason, a teaching-learning process for training mathematics student-teachers in Spanish university classrooms incorporating an assessment system that included keeping a learning portfolio was analysed. The objective was to assess each student's learning in reflection about his/her vision of the learning process developed in the university training classrooms, in knowledge of mathematical and methodological contents (knowledge) and in creativity. Rubrics were built for each case, with common criteria, to study the relationship between the outcomes obtained and to compare them with those of a final written exam. The results showed the difference between the assessment of student-teachers in reflection and the other aspects, and thus the need to use specific assessment instruments for the different capabilities being developed in the training process. 相似文献

“知识领域分类”是教学设计研究的一项基础性工作。国际上近50年来对知识领域分类的探索已形成诸多经典研究成果,如加涅的5种学习结果分类、布卢姆的6层次认知目标分类、梅里尔的学业水平与内容类别二维分类等。然而,这些知识领域分类框架在指导核心素养在课堂教学中的落地上仍然面临一些瓶颈。为此,在综合吸收和借鉴已有知识分类框架、学习科学与教学设计相关研究成果的基础上,可将知识领域划分为“是什么知识”“如何做知识”和“为什么知识”3种类型,具体再细分为事实、概念、程序(规则/步骤)、原理、策略和动力6种知识。其中,事实和概念属于“是什么知识”,程序/规则/步骤属于“如何做知识”,原理、策略和动力属于“为什么知识”。由此形成的学习过程循环可表征为“(动力与策略)+事实—概念—程序—原理+(动力与策略)”。核心素养在课堂教学中的落地,就是要将事实教学为主转向概念教学为主,然后再进阶到程序教学、原理教学、策略教学,同时确保有动力成分。对知识领域分类的探讨有助于教师明了教学目标的设置依据,在课堂上实现减负提质,选择合理的教学策略与评估方式,以及促进其完善最重要的教育专业知识。 相似文献

Two experiments investigated the whole number bias in the representation of fraction magnitudes with adults. A fraction magnitude comparison task was used where half of the comparisons were consistent with whole number ordering and the other half were not. Distance effects were found in Experiment 1 indicating that participants were comparing the magnitude of the whole fraction rather than just the parts. However, accuracy and response time also depended on the comparisons' consistency with whole number ordering. Experiment 2 manipulated the distance between the fraction pairs and showed that the whole number effect was strongest when the distance between the fraction pairs was very small. The results suggest that even skilled adults do not always have direct access to a fraction's magnitude on the number line. When the magnitudes are especially close together, adults may rely on alternative implicit or explicit strategies, such as examining the whole number parts, to evaluate the comparison. 相似文献
