This study examined the effects of an instructor's use of video casting as a nonverbal emotional cue in synchronous discussion sessions on students' social presence, satisfaction, and learning achievement. A quasi-experimental design was used to evaluate the effect of video casting in a synchronous virtual classroom. The research setting was a 100% online master's degree program within a university located in the midwestern United States. Thirty-three students participated in the experiment. The results showed a significant positive effect of the video casting on students' feeling of instructor copresence. No significant effect of video casting was found on either students' satisfaction or learning achievement. 相似文献

The current study assessed and compared university students' perceptions' of a novice and an experienced physics instructor's Pedagogical Content Knowledge (PCK). Two college physics instructors and 116 students voluntarily participated in this study. The research model comprised three workshops, mid-term and final evaluations and instructor interviews. The results showed that each instructor's PCK performance in four categories was slightly improved, though the difference was not statistically significant and only the category of Instructional Representation and Strategies (IRS) was found to be statistically different by students' evaluations of their instructor's PCK. The experienced instructor emphasized life examples and experiments, whereas, the novice instructor emphasized explanations and quizzes. Furthermore, the PCK questionnaire provided university instructors with adequate information so the instructors could receive students' feedback as available sources to reflect on their teaching to improve their quality of teaching. Research implications of this study are provided along with suggestions for future research. 相似文献

Although Vygotskian principles involving the Zone of Proximal Development (ZPD) are hailed as tenets undergirding teaching and learning within a constructivist setting, these principals have not been implemented widely within school classrooms. Tharp and Gallimore, building on the notion that learning can be maximized when a teacher has a heightened awareness of a student's ZPD and stimulates new learning based upon this understanding, argue that true teaching is a matter of “assisting performance”. This study examines the efforts of one university instructor to assist the performance of her graduate students as they learned to teach, scaffold and support struggling readers. The findings suggest that the university instructor successfully assisted her students by providing supportive feedback, extending their learning and providing appropriate resources through ongoing Email correspondence and face‐to‐face meetings and tutoring sessions. Success was attributed to the instructor's extensive knowledge of supporting struggling readers, awareness of her students' ZPD's in relation to the context of their learning and her efforts to consistently provide appropriate and specific feedback through iterative dialogue. 相似文献

Project-based learning engages students in problem solving through artefact design. However, previous studies of online project-based learning have focused primarily on the dynamics of online collaboration; students' knowledge construction throughout this process has not been examined thoroughly. This case study analyzed the relationship between students' levels of knowledge construction during asynchronous online discussions with respect to engagement in project-based learning. Graduate students' online postings in a course that comprised both project-based and non-project learning activities were coded and counted for knowledge construction, teaching, and social interaction moves using computer-mediated discourse analysis. Chi-square analyses found that the instructor's teaching discourse remained fairly consistent during project-based and non-project learning. Despite this, students' online discussions during project-based learning were characterized by more advanced levels of knowledge construction, where ideas were rationalized and integrated into plausible solutions. In contrast, students' online postings outside project-based learning rarely moved beyond the lower levels of information sharing and idea exploration. Based on these results, guidelines for designing and facilitating online project-based learning are presented and discussed. 相似文献

The rapid growth of online courses in higher education has led to developments in the field of e-assessment. This paper presents a study, which examined the quality of online academic courses using a multidimensional assessment of students' activities and perceptions, using educational data mining and an online questionnaire. The assessment focused on four aspects: instructional, communication, course workload and overall learning experience. The course instructional model was found well-structured. The video lectures, assignments and materials designed for the online course were the most used and contributing learning resources. However, the number of students who entered the video lectures decreased as the course progressed. Low activity was found in the discussion forums. Students perceived the course workload as low. Overall, the learning experience was high and the students were highly satisfied. These findings provide insights that may assist in improving the quality of future online courses. 相似文献

This study provides an example of one institution's efforts to design coursework that meets the simultaneous challenges of supporting the aims of increasing access to online courses and simultaneously better preparing teachers to work in diverse classrooms. Based on online pre- and post-surveys and monthly open-ended writing prompts administered to students in an introductory teacher preparation course, the study sought to discover students' motivation to select online or blended courses, student perspectives on the benefits and challenges to taking this course online, characteristics of the learning environment that promoted or interfered with students' learning, instructor's perspective of learners' reaction to topics addressing K-12 classroom diversity, and the impact of an online format on students' discussions of issues related to learner diversity. Findings suggest that online courses should include a classroom placement component in which students experience a diverse classroom in order to best prepare students for diverse teaching assignments. Thus, the best online teacher preparation courses maybe those that blend virtual and face-to-face interaction rather than being strictly online. 相似文献

Phenomena-based approaches have become popular for elementary school teachers to engage children's innate curiosity in the natural world. However, integrating such phenomena-based approaches in existing science courses within teacher education programs present potential challenges for both preservice elementary teachers (PSETs) and for laboratory instructors, both of whom may have had limited opportunities to learn or teach science within the student and instructor roles inherent within these approaches. This study uses a convergent parallel mixed-methods approach to investigate PSETs' perceptions of their laboratory instructor's role within a Physical Science phenomena-based laboratory curriculum and how it impacts their conceptual development (2 instructors/121 students). We also examine how the two laboratory instructors' discursive moves within the laboratory align with their's and PSETs' perceptions of the instructor role. Qualitative data includes triangulation between a student questionnaire, an instructor questionnaire, and video classroom observations, while quantitative data includes a nine-item open response pre-/post-semester conceptual test. Guided by Mortimer's and Scott's analytic framework, our findings show that students primarily perceive their instructors as a guide/facilitator or an authoritarian/evaluator. Using Linn's knowledge integration framework, analysis of pre-/post-tests indicates that student outcomes align with students' perceptions of their instructors, with students who perceive their instructor as a guide/facilitator having significantly better pre-/post-outcomes. Additional analysis of scientific discourse from the classroom observations illustrates how one instructor primarily supports PSETs' perspectives on authentic science learning through dialogic–interactive talk moves whereas the other instructor epistemologically stifles personally relevant investigations with authoritative–interactive or authoritative–noninteractive discourse moves. Overall, this study concludes by discussing challenges facing laboratory instructors that need careful consideration for phenomena-based approaches. 相似文献

The authors discuss a case study experience in conducting scientific courses such as Environmental Chemistry and Spectroscopy to different groups of undergraduates at Universiti Malaysia Sarawak (UNIMAS), using web-based learning environments to support conventional teaching/learning sessions. The authors discovered that by supplementing the learning online, students became more interested in their respective fields of study, and thus were able to participate in class discussions more freely. Online, a higher number of group activities can be organized to consolidate the learning of specific topics. The web-based learning environment also allows more interaction opportunities between peers and with the course instructor. Overall, the students reported they found that learning online made the course more interesting, and that the students were consciously aware that they learned more in the process. The paper also highlights the major benefits of conducting a course online from a course instructor's perspective. 相似文献

Instructors often show rhythmic movements with speech in video lectures. However, the effects of these movements have not been tested in video lectures with an instructor and visual learning material. Results of Experiment 1 showed students in the beat gestures and head nods conditions showed significantly less attention to the visual learning material, more attention to the instructor, whereas in the beat gestures + head nods condition drew significantly more attention to both. In Experiment 2 we tested whether the complexity of the visual learning material moderated the effects of rhythmic movements on students’ learning. When the presentation was simple, students in the head nods + beat gestures condition showed more positive interaction, and significantly better recall and transfer. The results have implications for video designing: if an instructor and simple learning material are visible, she is encouraged to show beat gestures and head nods to mark important information. 相似文献

The technology policies included on instructors' syllabi vary greatly and, in some cases, may unfavorably influence students' perceptions of the instructor. To examine this hypothesis, we randomly assigned college students enrolled in psychology courses at two different institutions (N = 163) to groups in which they viewed different syllabi for a community psychology course. The syllabi varied by the hypothetical instructor's technology policy (encouraging of appropriate technology use in the classroom, discouraging of all technology use, or a mixture of both) and instructor gender. Results showed that students rated instructors similarly on the Competency/Communication factor across all conditions but rated them significantly lower on the Rapport factor when the syllabus included a discouraging technology policy. Rapport ratings were also associated with students' self-reported dependence on technology. High instructor Rapport was associated with high levels of students' technology dependency in the encouraging technology policy condition (r = .29, p < .05), but low levels of technology dependency in the discouraging condition (r = ?.31, p < .05). Our findings suggest that if instructors include technology policies on their syllabi that restrict inappropriate technology use, they should also indicate situations in which technology use is appropriate. 相似文献

In this study, structural equation modeling is applied to examine the determinants of students' satisfaction and their perceived learning outcomes in the context of university online courses. Independent variables included in the study are course structure, instructor feedback, self‐motivation, learning style, interaction, and instructor facilitation as potential determinants of online learning. A total of 397 valid unduplicated responses from students who have completed at least one online course at a university in the Midwest were used to examine the structural model. The results indicated that all of the antecedent variables significantly affect students' satisfaction. Of the six antecedent variables hypothesized to affect the perceived learning outcomes, only instructor feedback and learning style are significant. The structural model results also reveal that user satisfaction is a significant predictor of learning outcomes. The findings suggest online education can be a superior mode of instruction if it is targeted to learners with specific learning styles (visual and read/write learning styles) and with timely, meaningful instructor feedback of various types. 相似文献

This paper examines BA Social Work students' experiences of developing their reflective skills to work with diverse communities using a technology‐enhanced blended learning design. In response to growing student numbers, new teaching and learning resources were developed to provide opportunities for students to engage in reflection‐in‐action at critical learning stages with the support of tutors and peers. It is suggested that access to online lectures, communications tools, a workbook (to record learning development) and online video case studies can encourage students to reflect‐on‐action, allowing them opportunities to reframe and reinterpret existing knowledge, values and beliefs to assess the impact these may have on their professional practice when working with diverse communities. To cater for an increase in student numbers, a rationale for the learning design is outlined, and the paper then explores the lessons learnt from the students' technology‐enhanced learning experiences. 相似文献

Online learning has become a reality for many students in higher education. Unfortunately, something that has also become a reality is a sense of isolation in online courses, and Moore (1980) has warned that students' sense of distance can threaten their ability to learn. The community of inquiry framework (Garrison, Anderson, & Archer, 2000) has provided insight into ways that online interactions can improve students' and instructors' social presence and learning. Emerging video technologies may be able to improve these interactions and thus more easily support the development of communities of inquiry. In this study we interviewed students in three distinct courses using different video-based instructional strategies. A large majority of students indicated feeling that the video-based communication made their instructors seem more real, present, and familiar, and that these relationships were similar to face-to-face instruction. Video communication impacted students' social presence in similar ways, although to a lesser degree than they believed it impacted instructor social presence. We conclude with discussion for future research and practice. 相似文献

This article describes a case study of the social construction of knowledge when undergraduate students are engaged in collaborative analysis of repertory grids produced by themselves and their instructor. The research is based on the elicitation of students' private understanding and instructors' public knowledge with the use of the repertory grid. This technique is derived from Kelly's personal construct psychology (Kelly, 1955), a constructivist theory that emphasizes the idiosyncratic nature of meaning. The teaching experience that follows was conducted adopting the educational paradigm of self-organized learning, in which the principles of constructivism, conceptual change, personal construct psychology, public knowledge and private understanding, and social learning are integrated to some extent. Results indicate that the repertory grid technique is (a) an approach that motivates students to be responsible for their own learning; (b) one means to get students to communicate their understanding and make this understanding open for inspection and scrutiny; (c) a way to negotiate the meanings of the concepts under study; (d) a tool to match students' understanding with their instructor's knowledge; and (e) a way for students to structure their knowledge. © 1996 John Wiley & Sons, Inc. 相似文献

Video lectures (VL), considered an effective means for delivering course content and infusing teaching presence in the virtual environment, have become very popular in education. The purpose of this study was to investigate online student experiences with VL focusing on their opinion of usefulness of VL, their satisfaction with them and their perception of learning derived from them. Our findings show that students' satisfaction with VL has a strong relationship with positive overall learning experience and perception of impact of video on learning. Furthermore, VL can enhance a feeling of engagement with content because of learners' control of the media and instructors' presence. The findings also alert us on the importance of careful planning and balanced integration of VL with other course materials. This provides important information on the effectiveness of video-lectures in college teaching and learning and implications for practice in online course design. 相似文献

The organization of conceptual materials: A methodology for measuring ideal and actual cognitive structures 总被引：1，自引：0，他引：1
Richard M. Fenker 《Instructional Science》1975,4(1):33-57
The teaching-learning process is described in terms of a simple communication model with four components: the sender, the encoding structure, the decoding structure, and the destination. Within this context a method is proposed and illustrated for evaluating a student's understanding of the system of concepts underlying the topic areas in an elementary statistics and measurement course. The method, multidimensional scaling, involves determining the students' and instructor's cognitive maps for the various topics. A cognitive map represents a hypothetical cognitive structure of a student or instructor which characterizes his perceived organization of the concepts in a topic area. These individual cognitive maps were compared to the optimal organization or formal structure, as a basis for assessing the students' under-standing of the material. The present research was exploratory but demonstrated that:
- With the help of experts it is possible to define the formal structure for the concepts in a topic area.
- It is possible to measure, in a classroom setting, the cognitive maps that both the students and instructors have for a topic area.
- By comparing individual students' cognitive maps to the instructor's cognitive map or to the formal structure, the student's understanding of the system of concepts defining the topic area can be evaluated.

The present study evaluated the students' psychological well-being, experiences, performance, and perception of learning regional anatomy remotely. A regional anatomy remote learning curriculum was designed and learning materials were delivered virtually to 120 undergraduate medical students at Jinan University, China. All the students consented and voluntarily participated in this study by completing self-administered online questionnaires including the Zung's Self-Rating Anxiety and Depression Scales at the beginning and end of the learning session. A subset participated in focus group discussions. Most of the students (90.0%) positively evaluated the current distance learning model. More than 80% were satisfied with the content arrangement and coverage. Many students preferred virtual lectures (68.2%) and videos showing dissections (70.6%) during the distance learning sessions. However, writing laboratory reports and case-based learning were the least preferred modes of learning as they were only preferred by 23.2% and 14.1% of the students, respectively. There was no significant lockdown-related anxiety or depression reported by students using depression and anxiety scales as well as feedback from focus group discussions. The surveyed students' confidence scores in distance learning were significantly higher after 5 weeks than at the beginning of the session (3.05 ± 0.83 vs. 3.70 ± 0.71, P < 0.05). Furthermore, the present results showed no significant differences between the current group's academic performance in the unit tests as well as the final overall evaluation for different parts of the course compared to that of the previous year's cohort. The findings above were congruent with focus group discussion data that the use of the online teaching platform for regional anatomy significantly improved the students' confidence in virtual and self-directed learning and did not negatively affect their academic performance. 相似文献

ABSTRACTOnline discussions are widely viewed as a valuable tool for encouraging student engagement and promoting interaction with course material outside of the traditional classroom. Strategies for conducting online discussions vary and are not confined to traditional, university-sponsored learning management systems (LMS). Social media platforms such as Facebook, which provide a variety of social benefits to students, might also represent a viable mechanism for educational information exchange and learning. Our study tested this proposition by comparing the effects of a Facebook-based and LMS-based online discussion forum on students' participation, achievement of learning goals, and overall course performance. Our findings suggest that different forums can affect classroom dynamics and student learning in different ways. While Facebook may be better at fostering student participation and encouraging peer-to-peer dialogue, the university-sponsored LMS may be a more effective tool for encouraging students to develop coherent arguments and apply course content in other contexts. Since this study shows that platform of an online discussion assignment matters, college instructors should consider the benefits and drawbacks of each platform before developing an online discussion assignment. Instructor choice of platform should depend on course content, instructor's teaching preferences, and online discussion assignment goals. 相似文献

This paper reports a study of preservice teachers who investigated their own teaching during a field-based component of a mathematics education methods course. The course was designed to engage the preservice teachers in both mathematical and pedagogical inquiry. Analysis of video recordings of course discussions, audiotaped interviews with preservice teachers, audiotaped discussions of instructor's planning meetings, and copies of the instructor's and preservice teachers' journals identified two critical incidents that depict students' resistance to the course directions. Analysis of these critical incidents suggests that prospective teachers' interactions with their students can become the mirror through which we can investigate their interactions with us, as teacher educators, and with our course activities. In this way we might reframe the problem of resistance to one of listening—listening to the students, to each other, and to ourselves. 相似文献

This article presents a case study of the use of digital video technology with a new pedagogical approach under a constructivist framework in an elementary school foreign language methods course. Data were collected through interviews with the methods course instructor, field notes, analytical notes from videotaped student presentations of their learning from the video clips, students’ mid‐semester evaluation of the use of video clips, and end‐of‐semester student reflections on open‐ended questions regarding the use of video clips. A careful examination of the data identified themes that illustrate the characteristics of the use of digital video technology under a constructivist framework. Those themes include the flexibility and capability of digital video technology, the development of the video clips, students’ ownership of knowledge, feedback from the students, and evaluation of the use of video clips. This case reports the vision of technology integration being realized. It results from the presence of technology, the instructor's pedagogical knowledge, and his or her content expertise. 相似文献
