ABSTRACTInstructional explanations have sometimes been described as an ineffective way to teach science, representing a transmissive view of learning. However, science teachers frequently provide instructional explanations, and students also offer them in cooperative learning. Contrary to the transmissive view regarding explanation, studies suggest that instructional explanations might be successful if they are based on an interaction between explainers and explainees, including the diagnosis of understanding and adaptation to the explainee’s needs. The present article has three goals: (1) It will propose a framework for potentially effective instructional explanations, presenting five core ideas of what constitutes effective instructional explanations and two concerning how they should be implemented into science teaching. (2) To justify the framework, the article will review studies on the effectiveness of instructional explanations. It will identify factors that have been researched for their impact on the effectiveness of instructional explanations and discuss them for their applicability to science teaching. (3) This article will connect the research on instructional explanations with the idea of basic dimensions of instructional quality in science. It will discuss the core ideas as particular expressions of the basic dimensions of instructional quality, specifically ‘cognitive activation’ and ‘constructive support’. 相似文献

There is a general consensus among researchers and teacher educators that classroom video can be a valuable tool for pre-service teacher education. Media such as video are not, however, in themselves effective. They have to be embedded in an instructional program to be useful. Yet, little empirical research examines how specific instructional approaches might effectively exploit the potential of video in teacher education. In this study we explored the use of two video-based university courses, one representing a cognitive instructional strategy integrating video, the other representing a situative strategy. Using data from learning journals we analyzed the effects of the two strategies on pre-service teachers’ (N = 28) ability to reflect on classroom video. We found that the two strategies have distinct impacts on the kinds of reflection patterns that are fostered. Our findings suggest that the learning goal and purpose at hand should determine which instructional strategy should be employed when embedding classroom video into teacher education courses. 相似文献

This study assessed the effect of design instructional video based on the Cognitive Theory of Multimedia Learning by applying segmentation and signaling on the learning outcome of students in an online technology integration course. The study assessed the correlation between students’ personal preferences (preferred learning styles and area of specialization) and their learning outcomes. A three-group pretest–posttest design was employed to assess whether there were significant differences in students’ test scores after they watched an instructional video. The results of the analysis of covariance (ANCOVA) analysis indicate that instructional design had a significant effect on students’ learning outcome. This effect was demonstrated by the statistically significant differences in students’ learning outcomes, with the highest scores achieved by students in the segmented and signaled video group and the lowest scores in the no-segmentation and no-signaling group. Moreover, results indicate that students’ learning preferences and area of specialization related significantly and positively to their learning outcomes. These findings suggest that the use of educational video in online courses has the potential to effectively improve students’ learning outcome; however, it requires design manipulation. The results also emphasize the importance of rethinking the one-size-fits-all approach in developing online course content and include consideration of the students’ learning preferences and area of specialization to optimize their learning. 相似文献

Does the use of musical accompaniment in instructional media enhance motivation and learning? Many instructional film producers avoid music in their presentations, but others regularly use music to accompany the instruction. Such differences in production may well affect the level of enjoyment, assimilation, retention, recall, transfer and application of the material to be learnt. This paper describes a study into whether the use of music on video‐mediated instruction has any effects on students’ learning. The study revealed only inconclusive differences in effect between video instruction accompanied with music and video instruction without music 相似文献

Looking at recent changes in the educational policy context, it is difficult to underestimate the central role of the principal. Principals must simultaneously perform different roles and implement activities of a varied nature. As an ‘instructional leader’, he or she must be able to create supportive links between the school and the classroom level. Individual learning and teachers’ professional development must be linked to, and supported by, an appropriate organizational development. As a ‘project manager’, the principal is expected to develop and implement a specific plan in order to solve particular problems indicated by the inspectorate. Both tasks — instructional leader and project manager — are illustrated in this chapter. 相似文献

Learning hierarchies have received much attention from developmental and instructional psychologists. This article notes that conceptual confusions and methodological deficiencies occur in much of the research so far published. The conceptual confusions concern the terminology used; the ‘likelihood’ or ‘causal’ relationships between elements in the hierarchy; the distinction between ‘prerequisition’ and ‘positive transfer'; the distinction between single pieces of learning and classes of learning; the inclusivity of hierarchical relationships. The methodological deficiencies arise from an inability to measure ‘causal’ relationships; the omission of measurements of ‘positive transfer'; the difficulty of measuring the range of possible relationships within a hierarchy; the need to remove instructional effects from hierarchy validation studies. It is concluded that these confusions and deficiencies preclude data from learning hierarchy studies from being used to diagnose learning failure and in test construction. Suggestions for alternatives to, and improvements on, current methods are made. 相似文献

AbstractThe study reported here examined college students’ academic self-efficacy, ‘academic press’ and learning achievement, as well as the association between these three variables within learning contexts using interactive whiteboard-based instruction. A quasi-experimental study was conducted using a sample (n = 103) of first-year college students in China. Participants were taught English by either an interactive whiteboard-based or traditional lecture-based instructional approach for three months. The results showed that the interactive whiteboard-based instructional intervention cultivated higher levels of academic press and academic self-efficacy among students and a significant, positive correlation was identified between these two variables. Students’ learning achievement was not affected by the instructional intervention. These results indicate that interactive whiteboard-based instruction offers some distinct benefits. In future work, additional research is needed to clarify how the instructional model relates to understanding learning achievement. 相似文献

Abstract In this study, the question was addressed which instructional conditions are required to teach students how they themselves can initiate and perform learning activities aimed at conceptual change. The CONTACT‐2 strategy (a computer‐assisted instructional strategy for promoting conceptual change in the domain of basic physical geography) served as starting point for the design of several training procedures aimed at enhancing self‐regulated learning. With the first experimental condition, strategic support was gradually withdrawn ('faded') within each instructional step, while, with the second experimental condition, the number of steps was reduced as the training continued. The original CONTACT‐2 condition served as control condition. Subjects were 65 fifth‐ and sixth‐graders (primary education). Dependent variables concerned students’ abilities to initiate and perform learning activities aimed at conceptual change, the quality of their conceptions, and their learning performance. Results suggested that ‘fading’ can be a fruitful instructional approach to foster self‐regulated learning aimed at conceptual change, provided that the ‘fading’ procedure is tuned to the students’ actual level of self‐regulated learning: external control should not be withdrawn until students are able (and prepared) to initiate and perform the learning activities being required. When these conditions are met, designing effective training procedures aimed at ‘learning for conceptual change’ seems possible. 相似文献

The effectiveness of a multidimensional Canadian sex education programme was evaluated using 240 Grade Nine students. The intervention was offered by representatives from various community groups and involved instructional classes on anatomy/physiology of the reproductive system and sexually transmitted infections, a video and group discussion on healthy relationships, a form of ‘peer education’ and discussion on teen pregnancy and HIV/AIDS, as well as a parent workshop and newsletter on teen sexuality. Respondents in the intervention and control groups completed a self‐administered questionnaire at baseline and one month after the programme. Compared with the control group, students in the intervention group showed positive changes in the areas of knowledge, sex‐role attitudes, sexual interaction values, and the perception that birth control is important. These results suggest that a collaborative effort of outside professionals from various community organisations and involvement of ‘peer educators’ to provide sexual health education in Grade Nine high school classes may be a useful strategy. 相似文献

教学视频因其多通道展现教学内容的特性而成为数字化学习资源的首选形态。线索作为教学视频中的重要引导性教学设计手段,探究其类型及学习者先前知识经验对学习效果的交互影响,有益于优化教学视频的设计策略。基于学习者先前知识经验水平(高水平和低水平)和线索类型(言语线索和视觉线索)两个维度,运用眼动追踪技术和认知负荷、学习满意度、学习效果等测量工具,通过实验考察二者对学习的影响及其内在机制后发现:学习者先前知识经验水平对认知负荷的影响显著;线索类型对学习满意度的影响显著,且线索类型与学习者先前知识经验水平在学习满意度上的交互效应显著;学习者先前知识经验水平对学习效果的影响显著,且线索类型与学习者先前知识经验水平在迁移测验成绩上的交互效应显著。实验结果表明,线索类型与学习者先前知识经验水平对学习满意度和学习效果存在明显的交互作用,即只有低知识经验水平学习者在学习含有视觉线索的教学视频后,学习满意度与学习效果才有显著提升。这可能是由于该类学习者在信息选择时存在困难,视觉线索可以帮助其提高信息搜索效率,而言语线索却会使其认知负荷超载。 相似文献

This paper examines whether a video produced by young African people could serve the goal of education for understanding ‘others’ in the context of Japan. This was investigated by assessing Japanese pupils’ perceptions of Africa before and after viewing a video produced by Kenyan students. Data were gathered from Japanese pupils’ drawings. The result suggests that, after seeing the test video, the pupils changed their perceptions of Africa significantly. This concluded that video can contribute to the goal of education for understanding ‘others’, but the effect must be reinforced by providing more information concerning Africa and encouraging interactions between Africa and Japan 相似文献

This case study is based on a research through design project (RTD) that focuses on a technical communication video of the live-action format. It investigates the usability and design-implications of a live-action how-to video, by means of analyzing user-centered data such as YouTube analytics data, usability, and comprehension assessments. In the study, four key live-action video affordances are identified: verifiability, comparability, recordability, and visibility. The identification of these affordances when related to the users’ assessments resulted in several design implementations that would warrant sought-for communication efficacies. Findings show that some assumed efficacies appear to be mitigated by the complexity and the density of the video information. One implication of this is that the implementation of conventional video editing techniques and the addition of on-screen text that serve to make content briefer and more concise into instructional live-action videos requires the technical communicator’s careful consideration. 相似文献

This study analyses middle school students’ interests in biology to provide information on instructional strategies and curriculum development in Korea. An instrument that measures interests was developed based on the middle school biology curriculum. It consists of 64 three‐point Likert‐type items (scores range from 0 to 2). The two components, ‘topic’ and ‘activity’, are composed of 64 items. The topic component and the activity component contain 11 domains and six domains respectively. Data were collected from 267 middle school students in Seoul (male: 169, female: 107). The levels of interest in topic and activity were almost the same and not high. The highest interest domains were ‘genetics’ in topics and ‘observing through a microscope’ in activities. The interest levels in the domain ‘plant morphology’ and ‘plant‐related activity’ were the lowest in each component. The interest level of the eighth graders was the highest found among students. Interest levels of females were lower than those of males in ‘environment and ecosystem’, ‘animal reproduction’ and ‘animal morphology’, but higher in ‘plant morphology’ and ‘plant related activity’ (p < 0.05). Among the topics, the ‘human biology’ domain correlated positively with the domains ‘genetics’, ‘environment and ecosystem’ and ‘respiration of animal and plant’. The correlation between the domains of ‘plant reproduction and nutrition’ and ‘plant development’ was significant in ‘activity’ (r > 0.50, p < 0.001). Consistencies in interests were suggested with respect to instructional strategy and curriculum design. 相似文献

In both education and training an important aspect of the design, development and delivery of learning is the role of individual differences between learners in terms of their ‘learning styles’. One may identify four broad categories of what have been termed ‘learning style’: (i) ‘cognitive personality elements’ (e.g. Witkin et al. 1977; Riding, 1991); (ii) ‘information‐processing style’ (e.g. Kolb, 1984; Honey & Mumford, 1992); (iii) ‘approaches to studying’ (e.g. Entwistle & Tait, 1994); (iv) ‘instructional preferences’ (e.g. Riechmann & Grasha, 1974). A study of 245 university undergraduates in business studies aimed to: (i) describe the range of individual differences present within the sample; (ii) investigate the relationship between learners’ cognitive styles, learning styles, approaches to studying and learning preferences; (iii) consider the implications of ‘learning style’ for teaching and learning in higher education. The present study suggested some overlap between the dimensions measured by the Learning Styles Questionnaire (Honey & Mumford, 1986; 1992) and the Revised Approaches to Studying Inventory (Entwistle & Tait, 1994). No statistically significant correlations were found between cognitive style, as measured by the Cognitive Styles Analysis (Riding, 1991) and any of the other ‘style’ constructs used. Further research is required to investigate these relationships, as is a large‐scale factor analytical study of the Honey and Mumford and Kolb instruments. The notions of whole brain functioning, integra‐tive approaches to studying and degree of learning activity are discussed. 相似文献

We present the results of a literature review of studies on teaching strategies for moral education in secondary schools (1995–2003). The majority of the studies focus on the ‘what’ and ‘why’, i.e. the objectives, of curriculum‐oriented moral education. Attention to the instructional formats for enhancing the prosocial and moral development of students (the ‘how’) is relatively sparse. Most studies on teaching strategies for moral education recommend a problem‐based approach to instruction whereby students work in small groups. This approach gives room for dialogue and interaction between students, which is considered to be crucial for their moral and prosocial development. Other studies discuss more specific teaching methods, such as drama and service learning. We conclude that the theoretical discourses on moral education are not reflected on the practice of curriculum‐oriented moral education and its effects on students’ learning outcomes. We recommend that future research on curriculum‐oriented moral education includes the subject areas encompassing moral issues and the social differences between students. 相似文献

This article reports on the findings of a study that investigated the effects of instructional conditions and prior experience on students’ self-reflection. The study was conducted with the use of a video annotation tool that was used by undergraduate performing arts students to reflect on their video-recorded performances. The study shows a consistent positive effect of previous experience with the video annotation tool for engagement with reflection. Graded instructional conditions with feedback had a positive effect on increasing higher order reflections particularly for students with prior experience with the video annotation tool for reflective purposes. The finding suggests that when including reflection in the curriculum, it is important to consider introducing it at a program or degree level rather than individual courses in order to provide an opportunity for students to gain experience with reflection and any particular tool that is used (e.g., a video annotation tool). Furthermore, reflective tasks should be scaffolded into the curriculum with ample opportunity for formative feedback and summative assessment in order to encourage higher order thinking and foster students’ metacognitive awareness and monitoring for increased goal-setting and acknowledgement of the motive or effect of their observed behavior. 相似文献

Online learning from video modeling examples, in which a human model demonstrates and explains how to perform a learning task, is an effective instructional method that is increasingly used nowadays. However, model characteristics such as gender tend to differ across videos, and the model-observer similarity hypothesis suggests that such characteristics may affect learning. Therefore, this study investigated whether the effectiveness of learning how to solve a probability calculation problem from video modeling examples would vary as a function of the model’s and observer’s gender. In a 2 (Model: Female/Male) × 2 (Observer: Female/Male) between-subject design, 167 secondary education students learned how to solve probability calculation problems by observing video modeling examples. Results showed no effects of Model or Observer gender on learning and near transfer. Male students reported higher self-efficacy than female students. Compared to a female model, observing a male model enhanced perceived competence more from pretest to posttest, irrespective of observers’ gender. Furthermore, learning from a male model was less effortful and more enjoyable for male students than for female students. These results suggest that gender of both model and observer can matter in terms of affective variables experienced during learning, and that instructional designers may want to consider this when creating (online) learning environments with video modeling examples. 相似文献

Education is characterized by at least the following features: (a) it offers learning environments that help students to achieve preset goals, (b) it induces learners to engage in relevant learning tasks, and (c) it offers support while learners execute learning tasks. Offering learning environments builds on the assumption that learners will actually engage in the learning tasks and use the support provided. There is, however, growing evidence, that in a lot of cases students do not comply with that assumption. By not engaging as expected in the learning tasks and/or by not (adequately) using the support, learners reveal the phenomenon of what could be called—at least from the perspective of the (designer of the) learning environment—‘instructional disobedience’. ‘Instructional disobedience’ occurs when learners do not act as expected from them in a learning environment. While the literature has already referred to faulty assumptions and specified conditions for the effectiveness of instructional interventions, it seems the phenomenon of instructional disobedience has not yet attracted systematic research attention. In this contribution, we want therefore further unravel the nature and relevance of the phenomenon. This is done by analyzing the occurrence of instructional disobedience, possible explanations and ways to deal with it. As a start we illustrate the phenomenon by providing some examples.

ABSTRACTResearch has demonstrated that teachers working in early childhood education and care (ECEC) are proficient in offering emotional support to young children, but markedly weaker when it comes to instructional support. We conducted a controlled experimental study in the Netherlands, to investigate the effects of targeted in-service training on improving teachers’ instructional support. Teachers (N = 72) were randomly assigned to four conditions: an intensive early childhood education (ECE) training (N = 17), video interaction guidance (VIG) (N = 16), a combination of both training programs (N = 18), or a control condition with no training (N = 21). Teachers’ interactive skills were measured pre- and postintervention, according the scales of the Caregiver Interaction Profile (CIP). The ECE training improved the proficiency of teachers’ verbal communication and offering developmental stimulation. VIG proved to be effective in teachers’ fostering positive peer interactions between children. Intensive and targeted training can successfully improve the quality of teachers’ instructional support in ECEC settings, although more research on effective elements of professional development of ECEC teachers is needed. 相似文献
