“凡事预则立,不预则废.”预习是学生学习行为的重要组成部分,与课堂学习、课后复习共同组成学习的三大支柱.而在小学语文学习中,预习则有着其他学科无可比拟的重要价值,对于学生课堂有效学习起着举足轻重的关键作用.学生在学习一篇课文前自觉进行预习,在上课时则能够集中注意力,自觉进行语言的理解与思考,能够随着教师的引导点拨进行顺畅地感知与体会,学习效率与效果自然都大幅提高.那么我们究竟该怎样将预习落到实处,规范学生的预习行为呢? 相似文献

养成预习习惯十分重要。预习是指在老师讲授新的课程内容之前,学生根据需要自主展开学习的过程,实际是学生的一种自学行为。预习的目的是在老师授课前,学生对将要讲授的内容有一个初步的学习和理解,了解下一阶段学习的重点和难点,了解自己在什么地方有疑难和问题,从而在听课时更有针对性,更好地掌握该阶段的学习内容。预习是课堂学习的“起跳板”,有了它,学生在课堂上将会跳得更高、跳得更远。 相似文献

随着教育步入智能时代,智能化的学生课堂行为识别变得越来越重要。但由于学生的课堂行为复杂多变,使得智能化的学生课堂行为识别存在困难。为了提高智能化学生行为识别的精度,文章首先采集了300名学生的7种典型课堂行为图像,并进行了数据预处理。随后,文章将已在ImageNet数据集上训练好的经典深度网络模型——VGG16网络模型迁移到学生课堂行为识别任务中。最后,通过与其它深度学习模型进行实验对比,文章验证了VGG16网络模型对学生课堂行为具有较高的识别精度。上述研究表明,基于深度学习的学生课堂行为识别能及时、精准地反馈学生的课堂学习情况,有利于教师改进教学方法、优化课堂教学与管理,从而提高教与学的效率,助力教学改革。 相似文献

课堂环境下的学习行为是学习者进行知识学习的外在表现形式,对学习行为模式的识别有助于教师把握不同学习群体的特征规律,从而设计差异化教学干预方案,以改善学生的学习成效。在文献分析的基础上,文章首先以苏南某地区J中学的初中生为调查对象进行了问卷调查,并基于分析结果对课堂学习行为进行分类与编码;随后,文章采用聚类分析法对不同学习行为进行序列转换分析,并设计了基于课堂表现数据的学习行为模式识别模型;最后,文章采用滞后序列分析法对不同类型学习者的学习行为序列转换进行分析,挖掘了不同类型学习者存在的问题学习行为,在此基础上设计了基于问题学习行为的教学干预机制,以帮助学习者转换学习行为模式,进而提高学习效果。 相似文献

The present study investigated the effects on students’ learning experience of adding a video of a teacher to an e-learning module. A total of 43 undergraduates were asked to learn the content of a pedagogical document either with or without a teacher video on the screen. Although video captures of teachers are increasingly being integrated into online courses, few studies have investigated their impact and the best way of optimizing them. According to the social-cue hypothesis, the presence of a teacher (face and gestures) positively influences learners’ motivation and engagement in their learning. By contrast, the interference hypothesis holds that the teacher’s presence can lead to poor performances, as it acts as a source of visual interference that diverts students’ attention away from the relevant information. By assessing subjective ratings and learning outcomes, the present study tended to support the social-cue hypothesis, as it showed that adding a teacher video on screen significantly improved students’ retention of the spoken explanations, without disturbing either their performances on diagram and transfer problems or the time needed to process the document. Eye-tracking data showed that students spent 25% of their time watching the teacher video. Adding this video had no significant observable effects on the subjective ratings (i.e., social presence, evaluation of the teacher’s motivational skills, situational interest, cognitive load). These results suggest that videos of teachers can be used to improve social cues in multimedia learning without creating interference effects. 相似文献

Unlike traditional teaching method,flipped classroom is a form of blended learning in which students learn content online by watching video lecture,usually at home,and students and teachers discuss and solve questions by more personalized guidance and interaction in class,instead of lecturing.Flipped classroom is very useful to vocational college English teaching. 相似文献

Preservice teachers were randomly assigned to 1 of 2 observation conditions: technology-supported practice in observation (TSPO) plus standard classroom placement observation, n = 31, and classroom placement observation (control), n = 31. Over a 10-week term, TSPO students augmented their classroom placement observations of their mentor teachers by engaging in technology-supported construction and video analysis of those mentors' teaching, while control students engaged in only the classroom placement observations. The authors used an online, computer-supported instrument that elicited written responses during observation of 3 different teaching videos to assess the participants' ability to identify, interpret, and analyze evidence of exemplary teaching. TSPO students significantly outperformed controls on all 3 video tests. Implications of these findings for teacher training in both traditional and online education programs are discussed. 相似文献

Instructional videos are widely used to study teachers’ professional vision. A new technological development in video research is mobile eye-tracking (MET). It has the potential to provide fine-grained insights into teachers’ professional vision in action, but has yet been scarcely employed. We addressed this research gap by using MET video feedback to examine how expert and novice teachers differed in their noticing and weighing of alternative teaching strategies. Expert and novice teachers’ lessons were recorded with MET devices. Then, they commented on what they observe while watching their own teaching videos. Using a mixed methods approach, we found that expert and novice teachers did not differ in the number of classroom events they noticed and alternative teaching strategies they mentioned. However, novice teachers were more critical of their own teaching than expert teachers, particularly when they considered alternative teaching strategies. Practical implications for the field of teacher education are discussed.

Teacher collaboration and support given from one teacher to another, focused on improving teaching and learning in the classroom, are notable by their absence in secondary schools in Bangladesh. This article identifies a number of constraints to developing a collaborative culture including the difficulty of the curriculum, the perceived low ability of many students, the teachers' own educational background and contextual factors which influence teachers' motivation. It suggests that informal collaboration for mutual support has the potential to increase teacher motivation but that this will only be achieved through building more collaborative ways of working through formal programmes grounded in classroom observation. It questions the validity for Bangladesh teachers of the model of teacher development programmes focused on teacher collaboration which emphasise teaching the ‘perfect’ lesson and suggests that without attention to student learning such programmes are unlikely to lead to increased collaboration or improved teacher practice in schools. 相似文献

While statistics is an essential topic for business students, many students experience barriers to successful learning due to anxiety, motivation, or difficulty with quantitative understanding. This research examines the use of online videos with an effort to explore the relationship between student characteristics, video usage, and course performance measures. In addition, the study examines student perceptions of the supplemental resources in an effort to examine the efficacy related to student learning and performance. This study seeks to confirm previous research regarding the benefit of supplemental video resources and extend the knowledge base by understanding the impact for various types of students (e.g., level of course, level of previous academic performance, etc.). The study found that the use of the video resources varies based on students’ previous math performance and the difficulty of the material. Student ratings indicate that the videos were helpful in learning the content and that they provided an important resource when students needed additional tools to master the material. Analysis of the results provides implications for understanding how different students use online videos and offers recommendations for educators and researchers about how to enhance student success in difficult statistics coursework. 相似文献
