To maximize the effectiveness of instructional explanations, they should be tailored to an individual learner. However, instructors are often not able to collect diagnostically relevant information about a learner to individualize their explanations. This is particularly true in computer-mediated settings where it is more difficult to thoroughly assess a learner’s understanding. We present an approach that provides instructors in asynchronous and text-based computer-mediated communication settings with information about a learner’s understanding that has sufficient diagnostic power to enable them to generate learner-tailored explanations. A series of experiments testing this approach suggest several conclusions. First, instructors need information about a learner to individualize explanations. Second, instructors are able to design explanations that are specifically adapted to a learner’s individual understanding. Third, learner-tailored explanations facilitate the processing of new information and make instructional communication more efficient. Fourth, learner-tailored explanations enhance a deep understanding of the information processed and make instructional communication more effective.  相似文献

Although instructional explanations are commonly used to introduce learners to new learning content, previous studies have often shown that their effects on learning outcomes are minimal. This failure might partly be due to mental passivity of the learners while processing introductory explanations and to a lack of opportunity to revise potential misunderstandings after working on introductory explanations. Against this background, we provided learners with two instructional support measures to optimise the introduction of new principles and concepts by providing instructional explanations in the domain of management theory: (a) prompts designed to induce inferences that are focused on the central content of the explanations, and (b) remedial explanations that are adapted to the learners’ knowledge gaps. We tested their effects in a 2 × 2 factorial experimental design with the following factors: (a) prompts designed to induce focused processing (with vs. without), and (b) remedial explanations (adapted vs. random). The participants consisted of 80 psychology students. We found that the prompts fostered both the share of deep-oriented processing and the acquisition of conceptual knowledge. The beneficial effect of prompts on conceptual knowledge was mediated by the number of inferences that learners generated in response to the prompts. In addition, we found that prompts also fostered the instructional efficiency of providing instructional explanations. The provision of adapted remedial explanations, however, fostered neither deep-oriented processing nor the acquisition of conceptual knowledge. We conclude that prompts designed to induce focused processing can foster deep-oriented processing as well as both the effectiveness and efficiency of learning from instructional explanations.  相似文献

The worked example effect within cognitive load theory is a very well-established finding. The concrete effectiveness of worked examples in a learning situation, however, heavily depends on further moderating factors. For example, if learners improve their processing of worked examples by actively explaining the worked examples to themselves, they are usually better able to solve transfer problems. Another way to enhance example processing is to present learners with instructional explanations instead of prompting them to produce these explanations on their own. In this article, we review 21 experimental studies to address the issue whether instructional explanations support example-based learning. Meta-analytic results lead to three important conclusions: First, the benefits of instructional explanations for example-based learning per se are minimal. Second, instructional explanations are more helpful for acquiring conceptual knowledge than for acquiring procedural knowledge. Third, instructional explanations are not necessarily more effective than other methods supporting example processing such as self-explaining.  相似文献

Providing prompts to induce focused processing of the central contents of instructional explanations is a promising instructional means to support novice learners in learning from instructional explanations. However, within research on the expertise reversal effect it has been shown that instructional means that are beneficial for novices can be detrimental for learners with more expertise if the instructional means provide guidance that overlaps with the internal guidance provided by the prior knowledge of learners with more expertise. Under such circumstances, prompts to induce focused processing might even be detrimental for learners with expertise whose prior knowledge already provides internal guidance to learn from explanations. On this basis, we aimed at experimentally varying expertise by developing prior knowledge. Specifically, we used a preparation intervention with contrasting cases to enhance learners’ prior knowledge (expertise). Against this background, we tested 71 university students in a 2 × 2 factorial experimental design: (a) Factor of expertise. Working with contrasting cases to develop prior knowledge and expertise to provide internal guidance to learn from instructional explanations (with vs. without), (b) Factor of prompts. Prompts to induce focused processing of the explanations (with vs. without). The results showed that prompts to induce focused processing fostered conceptual knowledge for novice learners whereas prompts hindered the acquisition of conceptual knowledge for learners with expertise that was developed by working with contrasting cases beforehand. Moreover, measures of subjective cognitive load and learning processes suggest that the instructional guidance provided by prompts compensated for the low internal guidance of novice learners and overlapped with the internal guidance of learners with expertise.  相似文献

Recent developments in strategy instruction research suggest that learning in a particular discipline is enhanced by guiding students through the development of content-relevant metacognitive strategies. The potential of such an instructional approach for university settings is discussed in this paper, and is supported with evidence from an experimental field study. The study, conducted with 28 experimental and 28 matched control students over 13 weeks of an introductory computer science course, involved (a) students' development of a metacognitive strategy relevant for computer programming, (b) modelling and coaching procedures with complete explanations about strategy use, and (c) a socially supportive learning context. The instructional method had significant short-term and long-term effects on students' cognitive and affective learning outcomes.  相似文献

Abstract

In the present study the relationship between teaching and learning was examined using a conceptual framework that links dimensions of instructional tasks with gains in student learning outcomes. The greatest student gains on a performance assessment consisting of tasks that require high levels of mathematical thinking and reasoning were related to the use of instructional tasks that engaged students in the “doing of mathematics” or the use of procedures with connections to meaning. In addition, student performance gains were greater for those sites whose tasks were both set up and implemented to encourage the use of multiple solution strategies, multiple representations, and explanations. Whereas, student performance gains were relatively small for those sites whose tasks tended to be both set up and implemented in a procedural manner and that required a single solution strategy, single representations, and little or no mathematical communication.  相似文献

Recent research has shown that learning from worked-out examples is of major importance for initial skill acquisition in well-structured domains such as mathematics. However, only those learners who actively process the presented examples profit noticeably from this learning mode. Specifically, the learning outcomes depend on how well the learners explain the solution steps presented in the examples to themselves (‘self-explanation effect”). In a series of studies on learning mathematics from examples, learners’ spontaneous self-explanations and instructional means used to encourage self-explanations were investigated. In this research, the following main findings were obtained. Most learners were rather passive with respect to their spontaneous self-explanations. Among the active and successful learners, two subgroups employing different self-explanation styles could be identified. With regard to the instructional means used to induce effective example processing, it turned out that to employ “learning by teaching” in order to stimulate explanation activities was of very limited use. Attempts to directly train for or elicit certain types of self-explanations were more successful. However, even in the latter case, self-explanations had inherent deficits (e.g., proneness to errors). Thus, we sought to design learning arrangements that try to integrate self-explanations with well-timed and well-adapted instructional explanations (e.g., from tutors) in order to enhance students’ problem-solving skills.  相似文献

There is evidence that negative correlations between student achievement and their enjoyment of instructional methods exist under certain circumstances. In aptitude‐treatment interaction (ATI) studies where two or more methods are allowed to interact with student aptitudes to predict enjoyment and achievement, it appears that students often report enjoying the method from which they learn the least. Selected ATI studies are reviewed, and an explanation is suggested which may account for the negative correlations between achievement and enjoyment in instructional settings. It appears that students make inaccurate judgments about the amount of effort they will have to expend to achieve maximum learning outcomes. Low ability students typically report liking more permissive instructional methods, apparently because they allow them to maintain a “low profile” so that their failures are not as visible. However, in order to experience maximum achievement low ability students require less permissive methods which lower the information processing load on them. High ability students like more structured methods which they believe will make their efforts more efficient when these lower load methods seem often to interfere with their learning. High ability students seem to learn more from more permissive approaches which allow them to bring their own considerable skills to bear on learning tasks.  相似文献

Although explanations are a common means of instruction, research shows that they often do not contribute to learning. To unravel the factors giving rise to the ineffectiveness of instructional explanations, we propose a framework that brings together empirical work on instructional explanations from a variety of research fields, including classroom instruction, tutoring, cooperative learning, cognitive skill acquisition, learning from texts, computer-supported learning, and multimedia learning. In our framework, we identify the distinctive characteristics of instructional explanations, present general guidelines for designing instructional explanations, and describe factors influencing both the generation and use of instructional explanations. It is argued that future research should uncover in more detail the interrelations between the different aspects of providing and using instructional explanations and their specific effects on learning.  相似文献

Teaching other students in a face-to-face manner has been shown to effectively foster both one’s own and their learning. This study experimentally investigated whether and how tutors and tutees academically benefit from three phases of face-to-face teaching: preparing-to-teach, initial-explanation, and interaction phases. Japanese undergraduates (n = 80) acted as tutors or tutees in peer tutoring. After studying with the expectation of teaching face-to-face or taking a test (the preparing-to-teach phase), tutor participants provided tutee participants with initial instructional explanations, without asking or answering questions (the initial-explanation phase), and then engaged in a question-and-answer period (the interaction phase). Tutor and tutee participants learned better by providing and receiving higher-quality explanations in the initial-explanation and interaction phases. Face-to-face teaching vs. test expectancy had no effects on the quality of tutor participants’ explanations or their learning outcomes. The results suggest that both the initial-explanation and interaction phases contribute to learning by teaching face-to-face, whereas the preparing-to-teach phase does not.

In this paper an approach to the writing of evaluation questions is outlined and developed which focuses attention on the question of the effectiveness of an educational design for bringing about the learning it is intended to facilitate. The approach develops from the idea that all educational designs rely on instructional alignment, implicitly or explicitly, and succeed or fail to the extent to which the implementation of that alignment is effective. The approach to evaluation that is described, design‐focused evaluation, utilises students’ experiences of instructional designs and strategies and focuses questions on students’ awareness of the effectiveness of those strategies for facilitating the intended learning outcomes. Detailed advice is given on the construction of items that fit with the approach described and that maximise the generalisability of the approach to most if not all educational settings and designs.  相似文献

This article provides quantitative evidence on the effect on learning outcomes of contrasting teaching styles applied to a class of Level 3 final-year students on a BTEC Applied Science course within a further education college in the UK. Two topics within a unit were taught using either a student-centred or teacher-centric (instructional) approach. Learning outcomes were monitored via tests aimed at both surface and deeper learning. Analysis showed that there was no significant difference between instructional or student-centred modes of teaching with respect to surface learning outcomes. However, analysis showed that a significant difference (p = 0.025) had occurred in deeper learning outcomes between the two modes of teaching. Interestingly, in this study, deeper learning was significantly improved after instructional teaching as opposed to student-centred teaching. Possible reasons for this are discussed and related to the role of instruction in vocational science education within FE. Preferences for teaching style were also obtained from the students via a survey and this indicated that PowerPoints were considered helpful whereas practical work and research tasks were very helpful to their learning.  相似文献

Recent studies have tested the addition of worked examples to tutored problem solving, a more effective instructional approach than the untutored problem solving used in prior worked example research. These studies involved Cognitive Tutors, software designed to support problem solving while minimizing extraneous cognitive load by providing prompts for problem sub-goals, step-based immediate feedback, and context-sensitive hints. Results across eight studies in three different domains indicate that adding examples to Cognitive Tutors is beneficial, particularly for decreasing the instructional time needed and perhaps also for achieving more robust learning outcomes. These studies bolster the practical importance of examples in learning, but are also of theoretical interest. By using a stronger control condition than previous studies, these studies provide a basis for refining Cognitive Load Theory explanations of the benefits of examples. Perhaps, in addition to other reasons, examples may help simply because they more quickly provide novices with information needed to induce generalized knowledge.  相似文献

ABSTRACT

Instructional 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

Example-based learning often follows a design in which learners first receive instructional explanations that communicate new principles and concepts and second examples thereof. In this setting, using the knowledge components of the instructional explanations to explain the examples (i.e., generating principle-based self-explanations) is considered to be a highly important learning process. However, a potential suboptimality of this learning process is that it scarcely requires learners to organize the content of the instructional explanations into coherent mental representations. Thus, in two experiments we investigated whether prompting learners to organize the content of the instructional explanations before providing them with the examples (and self-explanation prompts) enhances the effectiveness of example-based learning. We consistently found that organization prompts fostered learning regardless of whether the learners also received self-explanation prompts. Hence, in example-based learning, learners should be prompted to not only generate principle-based self-explanations but also to organize the content of the instructional explanations.  相似文献

Note taking and verbalization are considered as instrumental student activities which influence the relationship between the learning task and the learning outcomes. Research has demonstrated no significant relationships between the type of test anticipated and the amount of notes taken. The time interval between the presentation of the instructional stimuli and the criterion test does influence the amount of notes taken with a delayed test expectancy resulting in more note taking activity than immediate test expectancy. The probability of a student recalling an item on a test is greater if that item is present in the notes than if it is not present. Studies which compared note taking to no note taking conditions have shown a facilitative effect for note taking, but the effect is influenced by type of review condition and the time interval between note taking and criterion test. Research on the effects of verbalization in instructional settings has failed to show any clear benefits for methods which involve greater student verbalization. Controlled laboratory studies have shown that overt verbalization positively influences associational learning, serial learning, and discrimination learning. Alternative theoretical explanations for the effects of note taking and verbalization are discussed, and a structure for future research on these topics is provided.  相似文献

This study examined student learning outcomes for accelerated degree students as compared to conventional undergraduate students, disaggregated by class levels, to develop strategies for then closing the loop with assessment. Using the National Survey of Student Engagement, critical thinking and oral and written communication outcomes were examined. Within- and between-group learning outcome differences with freshmen and seniors in both instructional formats were tested to determine if instructional goals were met and student learning transpired. A quantitative, single case analysis method was used to determine significance with the items relating to these outcomes. Results indicated that seniors in both instructional formats typically reported greater engagement scores than freshmen, and that accelerated students tended to report more engagement than their conventional counterparts. These findings were most robust for the critical thinking outcome. Ramifications for student learning and relevant instructional formats are then explored, so as to close the loop with assessment.  相似文献

Instructional communication behaviors have been routinely associated with student learning outcomes for the past 40 years; however, the explanations for why these relationships exist remain somewhat controversial. Specifically, the relationship between immediacy and learning outcomes continues to be disputed. This study used Self-Determination Theory to evaluate the utility of students’ need for relatedness and their intrinsic motivation to learn as sequential mediators of the teacher immediacy-student learning relationships. Results of a structural equation model supported the theory’s hypothesis, as relatedness and intrinsic motivation to learn operated in serial to mediate the immediacy-learning relationship. These results indicate Self-Determination Theory is a well-suited framework for explaining the relationship between instructors’ communicative behaviors (e.g., immediacy) and their effects on student outcomes.  相似文献

This article is the second of two feature articles in this Journal, providing a summary of the literature review contained in Volume Two of the DETYA Report, Mapping the Territory: Primary students with learning difficulties in literacy and numeracy. The first article (Volume 6, No.1, March 2001, pages 12–19) examined definitions of learning disability and explored the loci of learning difficulties and their influence on literacy and numeracy development. This second article summarises the last three sections from the review. Section Three explores effective instructional techniques and programs in literacy and numeracy for students with learning difficulties. After that, effective service delivery approaches within regular settings are examined in Section Four. Finally, issues in program evaluation and measurement of outcomes are addressed in Section Five.  相似文献
