Research in multimedia learning lacks an emphasis on individual difference variables, such as working memory capacity (WMC). The effects of WMC and the segmentation of multimedia instruction were examined by assessing the recall and application of low (n=66) and high (n=67) working memory capacity students randomly assigned to either a segmented instruction (SI) or non-segmented instruction (NSI) version of a multimedia tutorial on historical inquiry. WMC was found to have a significant, positive effect on participants' recall and application scores; however, the use of segmentation mediated the effects of WMC to allow learners with lower WMC to recall and apply equal to those with higher WMC. 相似文献

What is the role of motivation in multimedia learning? Cognitive theories of multimedia learning tend to focus on instructional methods aimed at reducing extraneous processing (such as highlighting the essential material) or managing essential processing (such as breaking a lesson into parts), whereas motivational theories tend to focus on instructional methods aimed at fostering generative processing (such as adding appealing graphics or challenging scenarios). Moreno's (2005) cognitive affective theory of learning from media is intended to better incorporate motivation and metacognition into theories of multimedia learning, helping to extend or clarify Mayer's (2009) cognitive theory of multimedia learning and Sweller's (Sweller, Ayres, & Kaluga, 2011) cognitive load theory. The research presented in this special section examines motivating instructional features intended to promote generative processing—such as adding appealing graphics (Magner, Schwonke, Aleven, Popescu, & Renkl, 2013; Plass, Heidig, Hayward, Homer, & Um, 2013) or challenging scenarios (D'Mello, Lehman, Pekrun, & Graesser, 2013). Overall, motivational features can improve student learning by fostering generative processing as long as the learner is not continually overloaded with extraneous processing or overly distracted from essential processing. 相似文献

This study investigated whether active learning within computer‐based training courses can be measured and whether it serves as a predictor of learner‐perceived course quality. A major corporation participated in this research, providing access to internal employee training courses, training representatives, and historical course evaluation data. Twenty sample courses were subdivided into 1,884 time‐based instructional events and categorized by eight design principles for learner engagement: attend, organize, recall, practice, interact, apply, explore, and absorb. This analysis produces a quantitative pattern for the cognitive activity a course encourages within the learner, summarized as the active learning index. A regression model, with the active learning index as a predictor variable for learner‐perceived course quality, resulted in a correlation coefficient of .83 (r2=.69) and a p‐value <.0001. These results suggest a framework for quantifying the active learning components in computer‐based training courses and guiding the work of instructional designers toward higher‐quality courses. 相似文献

Hypermedia learning environments (HLE) unevenly present new challenges and opportunities to learning processes and outcomes depending on learner characteristics and instructional supports. In this experimental study, we examined how one such HLE—MetaTutor, an intelligent, multi-agent tutoring system designed to scaffold cognitive and metacognitive self-regulated learning (SRL) processes—interacts with learner’s prior domain knowledge to affect their note-taking activities and subsequent learning outcomes. Sixty (N = 60) college students studied with MetaTutor for 120 min and took notes on hypermedia content of the human circulatory system. Log-files and screen recordings of learner-system interactions were used to analyze notes for several quantitative and qualitative variables. Results show that most note-taking was a verbatim copy of instructional content, which negatively related to the post-test measure of learning. There was an interaction between prior knowledge and pedagogical agent scaffolding, such that low prior knowledge students took a greater quantity of notes compared to their high prior knowledge counterparts, but only in the absence of MetaTutor SRL scaffolding; when agent SRL scaffolding was present, the note-taking activities of low prior knowledge students were statistically equivalent to the number of notes taken by their high prior knowledge counterparts. Theoretical and instructional design implications are discussed. 相似文献

In introductory information technology (IT) courses, communicating technical concepts so that they can be comprehended by all students, technical and nontechnical, has been a concern. Another challenge in such courses is to teach the real‐world applicability of technical concepts. In this conceptual article, we focus on a relatively unexplored issue in IT education—which instructional method is more effective in improving the learning outcomes of all students taking introductory IT courses. In doing so, we consider two instructional methods, lecture and multimedia case studies, and argue that either of these instructional methods, adopted singly, will be perceived by students as less effective in accomplishing learning outcomes than adopting a combination of the two instructional methods. Our arguments both augment existing knowledge about the differential influence of lecture and multimedia case studies on students’ learning outcomes and questions the wisdom of adopting either of these methods singly in introductory IT courses. We derive insights from the literature and anecdotal evidence, presented as four propositions, which illustrate the relationship between the two instructional methods and the specific learning outcomes students perceive they affect. 相似文献

Medical school curricula are undergoing transformational change in response to calls for integrating content across courses and years to enable better retention and application and for individualizing learning to meet the diverse backgrounds and thus differing needs of students. To address the related teaching challenges, faculty can employ solid principles of adult learning and instructional design and use teaching strategies that stimulate different learning styles. We developed laboratory sessions that follow a learner‐centered instructional design model we refer to as “PLHET,” reflecting the steps of preparing, linking, hooking, engaging, and transferring learning, and also applied teaching strategies that reflect Kolb's four styles of learning (accommodative, divergent, assimilative, and convergent). We utilized a group learning format to promote active learning, teamwork, and self‐direction. Preliminary data based on student surveys of laboratory activity show positive responses. In the future, we will test the hypothesis that this design will improve medical students' performance. Anat Sci Educ © 2013 American Association of Anatomists. 相似文献

Lifelong learning is intentional learning that people engage in throughout their lives for personal and professional fulfillment and to improve the quality of their lives. In today's climate of continual change and innovation, lifelong learning is a critical educational goal. In order to prepare people for lifelong learning, educational opportunities must develop their capacity for self‐direction, metacognitive awareness, and disposition toward lifelong learning. Several instructional features facilitate the development of metacognitive and self‐directed learning skills, and the disposition to lifelong learning: (1) student autonomy, responsibility, and intentionality; (2) intrinsically motivating learning activities; (3) enculturation; (4) discourse and collaboration among learners; and (5) reflection. This article describes and presents examples of how three teaching methodologies—problem‐based learning, intentional learning environments, and cognitive apprenticeship—employ these instructional features. 相似文献

Abstract Recent advances in computer‐based interactive digital technologies have presented a broad range of possibilities to create powerful presentations and instructional messages. However, incorporating these new technologies effectively is not a simple task because the design of effective computer‐based instructional material is a complex process. Successful design involves interactions between individual learner characteristics, instructional delivery media, the type of specific knowledge and skills being taught, and the strategies and methods used to teach the material. This paper discusses:
-
— The need for an Automated Instructional Design
-
— The integration of learning theory, instructional design and technology
-
— Some approaches for automating instructional design
-
— An exploration of ID Expert, ? an intelligent computer‐based multimedia instructional development system (beta version 1.0).

Abstract Developing effective strategies to support secondary students with learning difficulties is important because they are the most prevalent students with special educational needs in contemporary mainstream classes. A learner‐focused instructional approach that incorporates meaning‐making, student control, and acceptance of errors, combined with explicit instruction will facilitate the learning of students with learning difficulties. This approach derives from an instructional setting model of learning difficulties, as distinct from a deficit model or an inefficient learner model, and draws on principles from constructivist learning theory and whole language theory. Guided by this model and these principles, secondary teachers can design curricula and classroom environments that support the needs of all students. 相似文献

Educational researchers have suggested that the tension between the learner‐centred and teacher‐centred pedagogies represents a real classroom issue that influences teaching and learning. This issue may be particularly significant in East‐Asian countries such as Taiwan due to some cultural influences. For example, teacher authority is highly valued in the culture. Accordingly, the present study aims to develop a questionnaire—the Teacher Authority Survey (TAS), with actual and preferred versions—to explore students’ perceptions/preferences regarding teacher authority in the earth science course. The relationships among students’ perceptions/preferences for teacher authority, learning attitudes, and learning achievements were investigated. Six hundred and seventeen Taiwanese high school students were administered the TAS, the earth science attitudinal questionnaire, and achievement assessment. Both exploratory and confirmatory factor analyses indicated that the TAS developed in this study has satisfactory validity and reliability measures. Correlation analysis indicated that the classrooms more oriented to learner‐centredness were correlated with more favourable attitudes toward learning. Moreover, three clusters of preferred teacher authority—namely, teacher‐centred authority, uncertain authority, and sharing authority—were identified. Students who preferred sharing authority tended to have more favourable learning attitudes, whereas students in the uncertain authority group seemed to have lower earth science attitudes and achievements. 相似文献

This self‐report study investigated 274 pre‐service teachers’ attitudes toward students with learning and behavioural difficulties (LBD) and the factors that predict their attitudes. Using four scenarios describing students with LBD, we investigated the degree to which pre‐service teachers’ open‐minded thinking dispositions, readiness to learn about students with LBD, beliefs about the role of regular classroom teachers in providing for these students, and emotions in relation to dealing with these students’ difficulties predict their likelihood of engaging in punitive reactions (e.g., giving a timeout) and planned behaviours (e.g., adapting instruction). Teachers with more open‐minded thinking dispositions and readiness to learn about students with LBD reported a higher likelihood of adapting instruction. Pre‐service teachers’ negative emotions partially mediated the relationship between their beliefs and punitive reactions and fully mediated the relationship between their open‐minded thinking dispositions and punitive reactions. 相似文献

This chapter argues for the recognition of the importance of student affective reactions in discussions of second language learning and teaching. It is argued that language learning is a particularly intense and ego-involving undertaking which requires a positive emotional stance on the part of the learner. The chapter reviews literature on how affective reactions — particularly motivation for language learning, foreign language anxiety, and student beliefs about language learning — impact on the language learning process and makes suggestions as to how teachers can promote positive affective characteristics. As affective variables represent the learner's willingness to engage in the activities necessary to develop second language proficiency, it is essential that teachers make the emotional needs of their students an instructional priority. 相似文献

The purpose of this study was to evaluate the instructional effects of using animations, static figures, PowerPoint bulletins,
and e-plus software as chemistry texts with the aid of computer-based technology. This study analyzed the characteristics
of students involved in three multimedia courses and their achievement and attitude toward chemistry and learning chemistry.
The three samples included in this study involved 257 undergraduate engineering students enrolled in the courses during the
academic year in which the study occurred. The results indicate that: (a) students acquired a better understanding of targeted
chemistry concepts during the multimedia courses, (b) some categories of students, based on their major area of study, computer
use, and attendance status at orientation achieved significantly (p < 0.05) higher post-test scores when adjusted for pre-test performance, and (c) significant differences and Cohen’s effect
sizes in attitudes toward chemistry and learning chemistry were detected for students’ level of computer use, disposition
toward computer multimedia, gender, and attendance at the multimedia orientation session. It appears to be helpful to incorporate
computer-based multimedia (animations, images, sounds) teaching while utilizing constructivist design principles to facilitate
students’ chemistry understanding and attitude toward chemistry and learning chemistry. 相似文献

This New Zealand‐based study of the classroom practice of nine exemplary teachers of writing to upper primary‐age students explored the significance of task orientation as a component of effective teacher instruction and the instructional strategies or actions that effective teachers utilise to promote such. Effectiveness pertains to teachers being able to generate a positive impact on learners' engagement and academic outcomes. Particular attention was given to the content and organisation of the tasks and activities that teachers required of their students. Analysis of observed teacher practice in relation to learner gains showed actions associated with task orientation to be strongly associated with student progress in writing. Two indicators linked particularly with learner gains in writing. They relate to teachers being able to select and promote learning tasks that are purposeful and challenging for students and to students being involved in the selection or construction of learning tasks. There were relatively high levels of proficiency with regard to teachers being able to select and promote purposeful and challenging tasks but significant operational variability with regard to teachers involving their students in task selection or construction. Classroom illustrations are provided on how effective teachers promote learner involvement in task selection or construction. 相似文献

Reform in science and mathematics curricula has moved from rote learning of facts and computation skills toward learning a structure of a subject matter. While the reasons for this shift, such as greater understanding, transfer and intellectual excitement are admirable, there is little empirical evidence to support them. A first step in examining such claims is to develop methodology for representing structure in the to‐be‐learned instructional material and in students' memories. The purposes of this paper, then, are to present (a) a method for examining a subject‐matter structure in prose materials, (b) methods for examining a subject‐matter structure in students’ memories, and (c) data bearing on the validity of structural interpretations of these measures. If these structures can be represented objectively and independently — even if not in a complete form or error free — a beginning has been made in validating the reasons for teaching structure. 相似文献

This article reports the outcomes of a project in which teachers' sought to develop their ability to use instructional practices associated with argumentation in the teaching of science—in particular, the use of more dialogic approach based on small group work and the consideration of ideas, evidence, and argument. The project worked with four secondary school science departments over 2 years with the aim of developing a more dialogic approach to the teaching of science as a common instructional practice within the school. To achieve this goal, two lead teachers in each school worked to improve the use of argumentation as an instructional practice by embedding activities in the school science curriculum and to develop their colleague's expertise across the curriculum for 11‐ to 16‐year‐old students. This research sought to identify: (a) whether such an approach using minimal support and professional development could lead to measurable difference in student outcomes, and (b) what changes in teachers' practice were achieved (reported elsewhere). To assess the effects on student learning and engagement, data were collected of students' conceptual understanding, reasoning, and attitudes toward science from both the experimental schools and a comparison sample using a set of standard instruments. Results show that few significant changes were found in students compared to the comparison sample. In this article, we report the findings and discuss what we argue are salient implications for teacher professional development and teacher learning. © 2013 Wiley Periodicals, Inc.

This study utilized qualitative and quantitative designs and eye-tracking technology to understand how viewers process multimedia information. Eye movement data were collected from eight college students (non-science majors) while they were viewing web pages containing different types of text and illustrations depicting the mechanism of atmospheric pressure and the formation of sea and land winds. The results showed that participants' eyes were fixated more often on the text than on the illustrations. Breaking the instructional multimedia into small successive segments did not seem to increase the number of eye fixations on the illustrations. Participants alternated their eye fixations on related components of the illustrations while focusing on verbs or sentences representing the kinematics of the weather systems. Text seemed to provide more detailed explanations than pictures and therefore served as the main resource for understanding the content. Scan paths revealed that participants were likely to be distracted by decorative icons in the illustrations. The decorative icons also created a split-attention effect on students' cognitive processing. Eye-tracking technology was found to be a valuable tool for achieving the objectives of this study, and it provided insights into students' cognitive processes during multimedia learning. Discussion and suggestions for instructional designers and future studies are provided. 相似文献

One set of instructional strategies which has not been examined vis‐a‐vis learning outcome is instructional simulations. The present study is an exploratory study designed to examine the possible relationship between designated roles and learning outcome. It was designed to explore the possibility that if differential learning outcomes existed they might be related to the designated role of the learner in the interactive simulation. The study found that students cast in the roles of managers in the SIMCORP SIMULATION reported different perceptions about learning than did students cast in the roles of workers. 相似文献

This discussion presents the author/classroom teacher's findings during an action research study evaluating the impact of photographic learning stories with young children. This is placed in the context of recent policy documentation that asserts the learner as a unique individual and literature promoting the need to support the development of positive learning dispositions and learner identity. The ethnographic study examines how learning stories can be developed as a tool to promote positive learning dispositions and support the mediation of home and school culture, suggesting that their potential lies in how they create an accessible and mutually constructed document that is accessed by children, parents and the teacher. The discussion supports reservations about the production of a definitive ‘list’ of dispositions and describes tensions between the aim of supporting positive dispositions and the unique learner in an education culture where effectiveness is measured by the statutory assessment of hierarchical goals. 相似文献
