Basic subjects in medical education, such as anatomy, are often taught through teaching formats that do not always sufficiently demonstrate the relevance of this basic information for clinical practice. Accordingly, it is a recent trend in anatomy education to link anatomical information more explicitly to clinical practice. This article presents an online video platform (Tuebingen’s Sectio Chirurgica [TSC]) as one means of explicitly integrating preclinical anatomical knowledge and clinical application. The purpose of the study presented here was to examine the effects of videos through which medical students were educated about Anterior Cruciate Ligament reconstruction. A TSC video about this surgical procedure was compared to a video with a traditional lecture providing the identical information. Participants (n = 114) perceived the TSC video to be superior in comprehensibility of the presentation (P = 0.003) and conceivability of the surgical procedure (P = 0.027), and to be more entertaining (P < 0.001). Moreover, participants in the TSC condition acquired more clinical knowledge than in the lecture condition (P = 0.043) but did not differ in their acquisition of anatomical knowledge. Mediation analyses indicated that the effect on the acquisition of clinical knowledge was mediated by comprehensibility, conceivability, and entertainment. These findings are discussed regarding their implications for medical education in terms of contributing to the general trend of linking preclinical anatomical knowledge to clinical application. A discussion about the limitations of the study and suggestions for future research are also provided.  相似文献

This paper explores the nature of prospective teachers’ noticing of students’ understanding as they analyze and discuss middle school students’ understandings of trapezoids in micro-case videos in the context of geometry. In this exploratory study, the data were obtained from eight prospective middle school mathematics teachers through individual video analysis, reflection papers, and group discussions. The results indicated that the use of purposeful micro-case video designs based on prospective teachers’ background knowledge of quadrilaterals allowed them to be productive in video analyses and discussions. In individual video analyses, prospective teachers attended to various mathematical elements to identify students’ responses but did not always use them to make interpretations of each student’s understanding of trapezoid. In the group discussions of the micro-case videos, in contrast, prospective teachers could provide alternative interpretations of students’ understanding by identifying links between the mathematical elements in students’ responses and the characteristics of students’ understandings. In the group discussions, they provided more detailed and specific instructional actions to support each student’s understanding of trapezoid than their individual video analyses. This study suggests practical implications for teacher education programs on how to use video cases (e.g., firstly, working individually and then having group discussions about the videos) to explore prospective teachers’ professional noticing skills. Considering prospective teachers’ background knowledge of related mathematical contents, this study can also inspire future studies on how to design effective videos about students’ mathematical understanding.

Although online education is popularized, it is in a developing stage that continues to struggle with communicating and engaging with students. The question remains on how students can be better engaged in online educational materials that are presented in asynchronous media, especially in lecture videos. Thus, using engagement theory, the present study explored how online lecture videos can be improved by incorporating entertainment education. Using a public lecture video found on YouTube, an online survey (N = 133) was conducted to identify digital storytelling techniques and their effects. Results revealed that these techniques that are often utilized in entertainment became meaningful components to increase student engagement and learning outcomes. However, they can also negatively affect instructor credibility, which could suggest the need to increase instructors’ skills. The implications for the development of lecture videos using entertainment and its potential to positively impact online education are discussed.  相似文献

Videos of classroom lectures have proven to be a popular and versatile learning resource. A key shortcoming of the lecture video format is accessing the content of interest hidden in a video. This work meets this challenge with an advanced video framework featuring topical indexing, search, and captioning (ICS videos). Standard optical character recognition (OCR) technology was enhanced with image transformations for extraction of text from video frames to support indexing and search. The images and text on video frames is analyzed to divide lecture videos into topical segments. The ICS video player integrates indexing, search, and captioning in video playback providing instant access to the content of interest. This video framework has been used by more than 70 courses in a variety of STEM disciplines and assessed by more than 4000 students. Results presented from the surveys demonstrate the value of the videos as a learning resource and the role played by videos in a students learning process. Survey results also establish the value of indexing and search features in a video platform for education. This paper reports on the development and evaluation of ICS videos framework and over 5 years of usage experience in several STEM courses.  相似文献

The use of videos on the internet has grown significantly in the last few years. For example, Khan Academy has a large collection of educational videos, especially on STEM subjects, available for free on the internet. Professional panoramic video cameras are expensive and usually not easy to carry because of the large size of the equipment. Recently, at least two companies have launched a new type of product that enabled panoramic video for certain smartphone users. The aim of this article is to analyze how panoramic video can be adopted, how attractive it is for actual everyday use, how it is used today, and how technology and other solutions should develop to become popular and accessible for mainstream users in learning applications. This research is based on the qualitative research method, namely content analysis. The analysis involved 1595 panoramic videos that users posted to two panoramic video sites. The videos represent a snapshot of videos from the beginning of the panoramic video sites. The videos were classified in 22 groups. In addition, the comments and discussions related to each of the videos were analyzed. Based on the study, it is concluded that panoramic videos are not yet widely used for learning, even though they have much potential for this purpose. Panoramic videos are good for documenting complex interaction situations in settings where a lower image quality is sufficient. Typical social media features are present in panoramic video sites, but they do not provide any extra support for learning or collaboration.  相似文献

Leveraging the power of music to improve science education   总被引：1，自引：0，他引：1  
We assessed the impact of music videos with science-based lyrics on content knowledge and attitudes in a three-part experimental research study of over 1000 participants (mostly K-12 students). In Study A, 13 of 15 music videos were followed by statistically significant improvements on questions about material covered in the videos, while performance on ‘bonus questions’ not covered by the videos did not improve. Video-specific improvement was observed in both basic knowledge and genuine comprehension (levels 1 and 2 of Bloom’s taxonomy, respectively) and after both lyrics-only and visually rich versions of some videos. In Study B, musical versions of additional science videos were not superior to non-musical ones in their immediate impact on content knowledge, though musical versions were significantly more enjoyable. In Study C, a non-musical video on fossils elicited greater immediate test improvement than the musical version (‘Fossil Rock Anthem’); however, viewers of the music video enjoyed a modest advantage on a delayed post-test administered 28 days later. Music video viewers more frequently rated their video as ‘fun’, and seemed more likely to revisit and/or share the video. Our findings contribute to a broader dialogue on promising new pedagogical strategies in science education.  相似文献

Mobile phones and advanced web-based video tools have pushed forward new paradigms for using video in education: Today, students can readily create and broadcast their own digital videos for others and create entirely new patterns of video-based information structures for modern online-communities and multimedia environments. This paradigm shift in video usage can be used for advanced learning about complex topics in higher education, for example, learning about socio-scientific or medical topics. Yet–technology aside–applicable educational concepts using collaborative video creation as a method need to be developed. In the present study, we investigate a specific concept designed to fight obesity stigmatization by developing knowledge using a learning-through-design-approach. We expected that creating videos can actually contribute to a deeper understanding of obesity and to a reduction in stigmatizing attitudes–when compared to a control condition. Dependent measures were based on the students’ video products, obesity-related knowledge and attitudes. The course group assessed their own knowledge on causes of obesity and stigmatization because of obesity higher in the post-test than a control group who read a newspaper article on the topic. A corresponding significant reduction in stigmatizing attitudes was found. In sum, results indicate significant differences between students who produced YouTube videos and a control group of students. The results are interpreted as a confirmation of our initial assumptions and evidence indicating that the program is successfully applicable in higher education.  相似文献

There are enough worthwhile videos available today so that a Lamaze Certified Childbirth Educator could literally teach an entire class series using only videos and feedback discussion. In this column, the author explores considerations in choosing videos for adult learners in Lamaze birth classes. Some things to consider when using videos should be the adult learner’s attention span, whether the video increases fear of birth or empowers the learner, and if the video is appropriate for the culture of the class participants. Finally, the author provides a list of some of the many wonderful videos available to Lamaze birth educators.  相似文献

Video lectures are fast becoming an everyday educational resource in higher education. They are being incorporated into existing university curricula around the world, while also emerging as a key component of the open education movement. In 2007, the Universitat Politècnica de València (UPV) implemented its poliMedia lecture capture system for the creation and publication of quality educational video content and now has a collection of over 10,000 video objects. In 2011, it embarked on the EU-subsidised transLectures project to add automatic subtitles to these videos in both Spanish and other languages. By doing so, it allows access to their educational content by non-native speakers and the deaf and hard-of-hearing, as well as enabling advanced repository management functions. In this paper, following a short introduction to poliMedia, transLectures and Docència en Xarxa (Teaching Online), the UPV’s action plan to boost the use of digital resources at the university, we will discuss the three-stage evaluation process carried out with the collaboration of UPV lecturers to find the best interaction protocol for the task of post-editing automatic subtitles.  相似文献

Seventy students participated in an experiment to measure the effects of either providing explanations or listening during small group discussions on recall of related subject-matter studied after the discussion. They watched a video of a small group discussing a problem. In the first experimental condition, the video was stopped at various points in time, enabling the participants to verbally respond to the discussion. In the second condition, they listened to the same discussion, without contributing. In the control condition, they listened to a discussion that was not related to the subject-matter subsequently studied. After the discussion, all participants studied a text and answered questions that tested their recall of information from this text. No immediate differences in recall were found. One month later, participants who had actively engaged in explaining remembered more from the text. The conclusion appears justified that actively providing explanations during a discussion positively affects long-term memory.  相似文献

This article characterizes my use of video as a tool for research, design and development. I argue that videos, while a potentially overwhelming source of data, provide the kind of large bandwidth that enables one to capture phenomena that one might otherwise miss; and that although the act of taping is in itself an act of selection, there is typically enough shown in a video that it rewards multiple watching and supports the kinds of arguments over data that are essential for theory testing and replication. In pragmatic terms, video presents phenomena in ways that have an immediacy that is tremendously valuable. I discuss ways in which videos help students and teachers focus on phenomena that might otherwise be very hard to grapple with. This article begins with a brief review of my uses of video, almost 40 years ago, for research and development in problem solving. It then moves to the discussion of very fine-grained research on learning and decision making. The bulk of the article is devoted to a discussion of the teaching for robust understanding (TRU) framework, which was derived in large measure from the extensive review of classroom videotapes, and which serves as the basis for an extensive program of pre-service and in-service professional development. The professional development relies heavily on the use of videos to convey the key ideas in TRU, and to help teachers plan and review instruction.  相似文献

Classroom discussion is frequently proposes as an essential part of democratic citizenship education. Literature, however, pays little attention to what kind of discussion is most effective and how teachers can facilitate a discussion. This study aims to contribute to the development of a framework for analysing the characteristics of classroom discussions and the different roles teachers can adopt in guiding a discussion on controversial issues. In addition, we investigated how the way teachers guide the discussion is related to the structure and content features of the discussion. The framework was used to analyse five classroom discussions in secondary education. Our framework appeared to be useful for revealing differences in the structure and content features of the classroom discussions and in the way teachers guide the discussion. The results also indicated that a high degree of teacher regulation was related to high content quality and more participation from students. A high degree of student regulation was linked to more genuine discussion among students. The study underlines the importance of taking account of the teacher’s role in research into the effectiveness of classroom discussions for democratic citizenship education and the study makes useful suggestions for teachers when preparing for a classroom discussion.  相似文献

New instructional technologies have been increasingly incorporated into the medical school learning environment, including lecture video recordings as a substitute for live lecture attendance. The literature presents varying conclusions regarding how this alternative experience impacts students' academic success. Previously, a multi‐year study of the first‐year medical histology component at the University of Michigan found that live lecture attendance was positively correlated with learning success, while lecture video use was negatively correlated. Here, three cohorts of first‐year medical students (N = 439 respondents, 86.6% response rate) were surveyed in greater detail regarding lecture attendance and video usage, focusing on study behaviors that may influence histology learning outcomes. Students who reported always attending lectures or viewing lecture videos had higher average histology scores than students who employed an inconsistent strategy (i.e., mixing live attendance and video lectures). Several behaviors were negatively associated with histology performance. Students who engaged in “non‐lecture activities” (e.g., social media use), students who reported being interrupted while watching the lecture video, or feeling sleepy/losing focus had lower scores than their counterparts not engaging in these behaviors. This study suggests that interruptions and distractions during medical learning activities—whether live or recorded—can have an important impact on learning outcomes.

Lecture videos are often praised as a great medium of instruction in online education. There is a lack of research, however, that tests whether videos are superior to other teaching tools in online classes. This article examines whether videos are better than lecture notes and still slides in an online introductory political science course. The results show that lecture videos might not be the best tool of instruction for introductory students. Students in the non-video course gave higher evaluations of the instructor and the course and scored higher on exams.  相似文献

This article reviews the international literature on video viewing in teacher education and professional development. Two hundred and fifty-five articles were collected, summarized and categorized using a conceptualization that includes four aspects: teachers' activity as they view a classroom video, the objectives of video viewing, the types of videos viewed, and the effects of video viewing on teacher education and professional development. The findings in each of these aspects suggested three main questions that may profitably guide future research: How can teaching teachers to identify and interpret relevant classroom events on video clips improve their capacity to perform the same activities in the classroom? How can we best articulate the diverse objectives of video viewing and the diverse types of videos in teacher education and professional development programs? How can we create a “continuum” between teacher education programs and professional development programs in such a way that video viewing becomes a routine, familiar professional practice able to produce the desired effects over the course of an entire teaching career?  相似文献

This study aimed to compare the effects of interactive and non-interactive videos concerning the autism spectrum disorder on medical students’ achievement. It also evaluated the relation between the interactive videos’ interactivity and the students’ decision-making process. It used multiple methods, including quantitative and qualitative methods. The participants were 60 medical students, divided into two groups. One group watched an interactive video while the other watched a non-interactive video. Pre- and post-tests were used to evaluate the students’ relevant achievements in each group. Moreover, a think-aloud protocol was used to evaluate the decision-making process of the group who watched the interactive video. The pre- and post-test results indicated an increase in the achievements of students in the tested groups. Students who watched the interactive video were found to be more successful. Finally, watching interactive videos was shown to positively affect medical students’ decision-making process.  相似文献

Can the planned social modeling of affective, group-focused, personal responses significantly increase such group behaviors in counselor trainees? In the study reported here 32 counselor trainees were randomly assigned to four practicum discussion groups: two video social model groups, one video lecture group, and one discussion group (eight in each group). Pre- and post-response frequencies were analyzed from audiotapes of the counseling groups to study type of delivery, content, process, and focus. Social modeling treatment significantly increased the response frequencies on all measures, while insignificant changes were generally found for the video lecture and group discussion treatments. Questions about social modeling variables and the usefulness of planned modeling in training are considered.  相似文献

Learning to conduct interactive classroom discussions is a high priority for becoming an effective teacher, and most teachers view conducting productive classroom discussions as a complex undertaking. Because the dynamics of facilitating classroom discussions are multifaceted and hard to analyze in real time, there is a growing interest in how video allows preservice teachers to examine records of their practice to promote further growth. What prospective teachers actually take away from analysis of video, however, needs further exploration. In this study, we explored five preservice student teachers’ beliefs about conducting discussions and probed the potential of videocase construction for supporting teacher learning by investigating the following question: ‘To what extent and how does making a videocase help preservice teachers investigate their facilitation of a subject‐specific discussion?’ Results revealed that by constructing and talking about their videocases, all five preservice teachers gained insights about how they lead discussions. Studying video excerpts and articulating what they saw in them provided a context for looking more closely at their own roles and student roles within their discussion. They also recognized the complexities of leading discussions and acknowledged particular areas that need improvement. The teachers used the metaphorical language of ‘guiding’ their students down a pathway when they talked about leading classroom discussions. There were similarities and differences among teachers’ conceptions of good discussions in English and science, and their notions of ‘guiding’ were related to their subject matter goals. The study suggests, however, several areas that may require further attention in preservice teachers’ preparation in leading discussions. Although the teachers expressed views of discussion that aligned broadly with disciplinary views in English or science, their language lacked specificity in what it means to develop varied interpretations of texts in English or consensus based on argument and evidence in science. More specific video analysis focused on subject matter goals and corresponding conversational elements may help preservice teachers develop more nuanced, sophisticated views of how particular types of social interaction have the potential to help their students reach specific subject matter goals. We conclude that investigation is needed on larger numbers of preservice teachers’ videocase construction processes, and further inquiry is needed into how working with video analysis affects their actual performance in future discussion facilitation.  相似文献

对分课堂：大学课堂教学改革的新探索   总被引：5，自引：0，他引：5  
针对当前高校课堂存在的主要问题,结合讲授式课堂与讨论式课堂的优点,提出了名为"对分课堂"的课堂教学改革新模式。其核心理念是分配一半课堂时间给教师讲授,另一半给学生讨论,并把讲授和讨论时间错开,让学生在课后有一周时间自主安排学习,进行个性化的内化吸收。对应的考核方法强调过程性评价,并关注不同的学习需求。试点教学表明,对分课堂有效增强了学生学习的主动性,教学效果良好。对分课堂有可能是一种适合中国国情的高校课堂教学模式,值得进一步尝试和推广。  相似文献
