谈及预习,对于语文学科而言,其重要性要大于其他学科。对于某些自然科学课程,如物理、化学,它们的很多规律、现象是要学生通过实验获知的,如果通过课前预习可以获知这些规律的话,那么新课学习中的实验探究就失去了价值和意义。而对于语文学科而言,学生凭借原有的语言文字功底,是可以通过预习获得良好的提升和拓展效果的。本文结合学生预习的实例,谈谈语文学习中课前预习的重要性和必要性。 相似文献

课前预习作为一个教学环节,不同的数学老师对此有着不同的看法。有人认为数学课的课前预习对于提高教学效果是有利的,而有些老师认为数学课的教学没有必有进行课前预习。其实,课前预习的利与弊不应该是取决于"预习"这个学习环节的本身,而应该取决于预习作业本身的内容。好的预习作业应该是对课堂教学效果起到积极作用的。本文将对预习作业的内容进行探究。 相似文献

在疫情防控的关键时期,规模化在线学习是落实“停课不停学”的重要方式。与以往的在线学习相比,规模化在线学习在学习场所、学习任务、学习同伴、思维方式、评价方式等多个方面发生了转变。它是教育信息化实践的一次特殊尝试,同时,其也在重塑在线学习的价值,形成了一种全新的学习生态。为了了解我国规模化在线学习的现状、准备度等情况,运用问卷调查法,对全国3148名学生进行调查研究,调查结果显示:一是在线学习满意度较低,感知教师支持较高,在线学习准备度一般。其中,在线交互效能感最高,计算机自我效能感准备不足;二是人口学因素对规模化在线学习准备度有不同程度的影响,年级、所在区域、每天在线学习时长所带来的差异影响显著;三是在线学习态度、教师支持、计算机自我效能感、自我导向学习、学习动机、学习控制力、在线交互效能感等,正向影响学生的在线学习满意度。因此,要提高规模化在线学习效果,可以从提升师生信息素养、加强培养自主学习能力、改善家校互动模式、增强教师支持、关注农村和留守儿童的在线学习等方面着手。在后疫情时期,还应进一步思考“教师如何迎接在线学习”“学生如何学习”“如何设计在线课程和实现优质教育资源共享”“在线学习如何与线下学习有机融合”等问题。 相似文献

Compared with research on the role of student engagement with expert representations in learning science, investigation of the use and theoretical justification of student-generated representations to learn science is less common. In this paper, we present a framework that aims to integrate three perspectives to explain how and why representational construction supports learning in science. The first or semiotic perspective focuses on student use of particular features of symbolic and material tools to make meanings in science. The second or epistemic perspective focuses on how this representational construction relates to the broader picture of knowledge-building practices of inquiry in this disciplinary field, and the third or epistemological perspective focuses on how and what students can know through engaging in the challenge of representing causal accounts through these semiotic tools. We argue that each perspective entails productive constraints on students’ meaning-making as they construct and interpret their own representations. Our framework seeks to take into account the interplay of diverse cultural and cognitive resources students use in these meaning-making processes. We outline the basis for this framework before illustrating its explanatory value through a sequence of lessons on the topic of evaporation. 相似文献

This paper uses measurements of learning inequality to explore whether learning interventions that are aimed at improving means also reduce inequality, and if so, under what conditions. There is abundant evidence that learning levels are generally low in low- and middle-income countries (LMIC), but there is less knowledge about how learning achievement is distributed within these contexts, and especially about how these distributions change as mean levels increase. We use child-level data on foundational literacy outcomes to quantitatively explore whether and how learning inequality using metrics borrowed from the economics and inequality literature can help us understand the impact of learning interventions. The paper deepens recent work in several ways. First, it extends the analysis to six LMIC, displaying which measures are computable and coherent across contexts and baseline levels. This extension can add valuable information to program evaluation, without being redundant with other metrics. Second, we show the large extent to which the disaggregation of inequality of foundational skills between- and within-schools and grades varies by context and language. Third, we present initial empirical evidence that, at least in the contexts of analysis of foundational interventions, improving average performance can reduce inequality as well, across all levels of socioeconomic status (SES). The data show that at baseline, the groups with the highest internal inequality tend to be the groups with lowest SES and lowest reading scores, as inequality among the poor themselves is higher than among their wealthier counterparts. Regardless of which SES groups benefit more in terms of a change in mean levels of reading, there is still a considerable reduction in inequality by baseline achievement as means increase. These results have policy implications in terms of targeting of interventions: much can be achieved in terms of simultaneously improving averages and increasing equality. This seems particularly true when the initial learning levels are as low as they currently are the developing world. 相似文献

This special issue was designed to promote an integration of mobile and psychological theories of learning by inviting empirical research that draws upon both theoretical approaches to guide investigation into learning involving mobile devices. Five empirical articles illustrated how mobile devices afford resources to learners and how new channels of data afford researchers new insight into learning processes. Authors of two invited commentaries note the challenges involved in researching mobile learning, which unfolds across multiple contexts and can involve novel tools, multiple learners, and instructors and experts. These authors propose a taxonomy that can organize research that investigates interactions amongst learners, instructors, experts, and tools across one or more physical contexts, as well as a research agenda that would empirically test and refine assumptions made by mobile learning theorists. In this commentary, the editorial team proposes that mobile and psychological theories may be improved through convergence. Theories of mobile learning can be advanced by adopting practices previously employed to refine psychological theories of learning, whereas conducting research using mobile devices (and the data they provide) can further refine psychological theories of learning. We illustrate these positions with examples, and consider how instruction must be designed and how learners must be prepared in order to benefit from learning using mobile technology. 相似文献

Tools for automatic grading programming assignments, also known as Online Judges, have been widely used to support computer science (CS) courses. Nevertheless, few studies have used these tools to acquire and analyse interaction data to better understand the students’ performance and behaviours, often due to data availability or inadequate granularity. To address this problem, we propose an Online Judge called CodeBench, which allows for fine-grained data collection of student interactions, at the level of, eg, keystrokes, number of submissions, and grades. We deployed CodeBench for 3 years (2016–18) and collected data from 2058 students from 16 introductory computer science (CS1) courses, on which we have carried out fine-grained learning analytics, towards early detection of effective/ineffective behaviours regarding learning CS concepts. Results extract clear behavioural classes of CS1 students, significantly differentiated both semantically and statistically, enabling us to better explain how student behaviours during programming have influenced learning outcomes. Finally, we also identify behaviours that can guide novice students to improve their learning performance, which can be used for interventions. We believe this work is a step forward towards enhancing Online Judges and helping teachers and students improve their CS1 teaching/learning practices. 相似文献

Bridging In-school and Out-of-school Learning: Formal, Non-Formal, and Informal Education 总被引：1，自引：0，他引：1
Haim Eshach 《Journal of Science Education and Technology》2007,16(2):171-190
The present paper thoroughly examines how one can effectively bridge in-school and out-of-school learning. The first part
discusses the difficulty in defining out-of-school learning. It proposes to distinguish three types of learning: formal, informal,
and non-formal. The second part raises the question of whether out-of-school learning should be dealt with in the in-school system, in view of the fact that we experience informal learning anyway as well as considering the disadvantages and difficulties
teachers are confronted with when planning and carrying out scientific fieldtrips. The voices of the teachers, the students,
and the non-formal institution staff are heard to provide insights into the problem. The third part discusses the cognitive
and affective aspects of non-formal learning. The fourth part presents some models explaining scientific fieldtrip learning
and based on those models, suggests a novel explanation. The fifth part offers some recommendations of how to bridge in and
out-of-school learning. The paper closes with some practical ideas as to how one can bring the theory described in the paper
into practice. It is hoped that this paper will provide educators with an insight so that they will be able to fully exploit
the great potential that scientific field trips may offer.
