The purpose of this study was to examine the effect of self-regulated learning strategies (SRLS) on performance in a learner-controlled and a program-controlled computer-based instruction (CBI). SRLS was measured using a self-regulated learning strategies questionnaire. Seventh-grade subjects were divided into high and low levels of SRLS and then randomly assigned to one of two versions of a CBI lesson: one allowing learner control over the sequence and content of the instruction and the other having the learners follow a linear instructional sequence. Results revealed that the performance differences between learners with high SRLS and those with low SRLS were greater under learner control than under program control (p<.05). Poor performance by subjects with low SRLS under learner control indicates a strong need for learners to possess self-regulatory learning strategies to achieve success under learner control. Program control, however, seems to minimize the performance differences between low and high levels of SRLS.  相似文献

This study investigated the influence of cognitive support for learning computer-based tasks using animated demonstration (AD) on instructional efficiency. Cognitive support included (1) segmentation and learner control introducing interactive devices that allow content sequencing through a navigational menu, and content pacing through stop and play buttons along with a slide bar for fast forward and rewind; (2) presentation modality and (3) a hybrid approach using a combined format of ADs with static graphics. Instructional efficiency was a combined effect of time-on-task during the learning phase and test performance. Time-on-task was included as a measurement to determine whether this would provide an alternative explanation for the benefits of learner control. Three learner-paced conditions with different types of cognitive support were developed, whereas a system-paced format, created without additional cognitive support, was used as a control condition. The learning task of this study was using graphic vector-based software Bezier tools to trace a cartoon. The results tended to suggest that the combination of different types of cognitive support (i.e. presenting the accompanying explanations as written captions to the learner-paced AD in visual-only instruction or combining learner-paced AD with static graphics in dual-modality instruction) had a positive effect, while learner pacing alone had not a significant positive effect.  相似文献

The interactivity principle in multimedia learning states that giving learners control over pace and order of instructions decreases cognitive load and increases transfer performance. We tested this guideline by comparing a learner-paced instruction with a system-paced instruction. Time-on-task and interactive behavior were logged, and were also related to interest, prior knowledge, and cognitive involvement. We successfully replicated the interactivity principle in terms of better transfer. However, this coincided with a large increase in time-on-task. Also, large individual differences existed in the use of learner control options, which were mostly unrelated to the other variables. Thus, the benefits of introducing learner control in multimedia learning are at the expense of learning efficiency, and it remains unclear for whom the interactivity principle works best.  相似文献

A possible explanation for why students do not benefit from learner-controlled instruction is that they are not able to accurately monitor their own performance. The purpose of this study was to investigate whether and how the accuracy of metacognitive judgments made during training moderates the effect of learner control on performance when solving genetics tasks. Eighty-six undergraduate students solved self-selected genetics tasks using either a full learner control or a restricted learner control. Results indicated that learner control effectiveness was moderated by the absolute accuracy (i.e., absolute bias) of metacognitive judgments, and this accuracy was a better predictor of learning performance for full learner control than for restricted learner control. Furthermore, students’ prior knowledge predicted absolute accuracy of both ease-of-learning judgments (EOLs) and retrospective confidence judgments (RCJs) during training, with higher prior knowledge resulting in a better absolute accuracy. Overall, monitoring guided control, that is, EOLs predicted time-on-task and invested mental effort regardless of the degree of learner control, whereas RCJs predicted the total training time, but not the number of tasks selected during training. These results suggest that monitoring accuracy plays an important role in effective regulation of learning from problem-solving tasks, and provide further evidence that metacognitive judgments affect study time allocation in problem solving context.  相似文献

‘'Learner control'’ refers to the proposal that learners will benefit if given more control over the pace or style of instruction they receive. It is often assumed that providing increased learner control will “accommodate”; individual differences. This article argues that such a view is naive. It is argued that research on learner control will benefit from (a) avoidance of reference to panacea, (b) basic work on a detailed taxonomy of the various forms learner control might take, and (c) a substantial review of related research which, while not labelled “learner control,”; has implications for the educational benefits that can be expected from giving learners control of certain aspects of instruction. Research examples are used to explicate these suggestions. It is concluded that no form of individualization of instruction, including learner control, has yet been shown to erase the relevance of prior individual differences to learning from instruction.  相似文献

This study investigated the effects of learner control and program control on the achievement and continuing motivation of high school students. The influence of the availability of computer-delivered instruction on student motivation was also examined. Continuing motivation was measured by student choice of learner control or program control as the mode for a second instructional program after subjects completed an initial program under their randomly assigned mode. Results revealed a highly significant difference in continuing motivation favoring learner over program control. The differences in posttest performance and performance during instruction between learner and program control were not significant. The data also revealed significant preferences to study both science and an alternative subject when they are presented by computer over when they are not.The research reported herein was conducted while she was a doctoral student at Arizona State University.  相似文献

This study investigated the potential benefits of a blended learning approach on the reading skills of low socioeconomic status students in Grades 1 and 2. Treatment students received English language arts instruction that was both teacher-led and technology-based. Comparisons were made with control students who received the same English language arts instruction without the blended learning component. Results showed significantly greater pretest/posttest gains on a standardized reading assessment for the treatment students compared to the control students. The greatest discrepancy occurred in reading comprehension. A sub-analysis of low-performing English language learner students in the treatment group revealed the largest reading gains. At posttest, these students performed at the level of non-English language learner students in the control group. Results indicated a blended learning approach can be effective in enhancing the reading skills of low socioeconomic students.  相似文献

Although research has indicated that augmented reality (AR)–facilitated instruction improves learning performance, further investigation of the usefulness of AR from a psychological perspective has been recommended. Researchers consider presence a major psychological effect when users are immersed in virtual reality environments. However, most research on learner presence has focused on measuring it rather than the factors influencing it. This study explored the relationship between learner perception and presence in an AR-facilitated learning environment. A game-type AR learning process was developed and an experiment was implemented employing a one-group pretest–posttest method. Three sets of research instruments were developed, comprising a learning achievement test, a learner's presence inventory, and a questionnaire on learners’ perception of the AR-mediated environment. A total of 60 validated data samples were collected and statistically analysed. The researchers determined that learner presence closely relates to learning achievement and AR learning perception. These results indicate that a more satisfactory AR perception leads to a higher level of learner presence in the AR environment, thereby resulting in more beneficial learning outcomes.  相似文献

This study was conducted to investigate the effects of variations in the design and delivery of interactive multimedia (IMM) on the learning and attitudes of elementary education majors. A multivariate analysis of variance was conducted with three independent variables—small group or individualized format, inductive or deductive design of instruction, and match of learner style to instruction—and four dependent variables—content scores, observation skill scores, overall satisfaction, and attitude toward learner control of instruction. Scores on the observation skills evaluation were significantly higher when the student's learning style was matched with the design of instruction. Satisfaction and attitude outcomes were significantly different for format: students in the small group were more satisfied, while those using the individual learning station were more strongly agreed that they controlled the pace and sequence of their own instruction. Content scores were not significantly different. In the future, the use of interactive multimedia with various formats and designs may serve to meet the needs of students with differing learning styles and at different developmental levels.  相似文献

Although considerable research has been conducted on both learner control and feedback, very little research has addressed the effect of giving learners control over the feedback that they receive. The purpose of this study was to examine the effect of learner control over feedback in a CAI lesson. Subjects used one of four CAI programs which provided either program control or learner control over verification or elaboration feedback. Results indicated that subjects who received elaboration feedback during instruction performed better than students who received verification feedback. Type of control did not have a significant influence on performance. However, when subjects selected feedback for items answered incorrectly during instruction, subjects under learner control/elaboration performed better on the posttest than subjects under learner control/verification. Implications for the design of CAI are discussed.  相似文献

Contrary to system-controlled multimedia learning environments, hypermedia systems are characterized by a high level of interactivity. This interactivity is referred to as learner control in the respective literature. For several reasons this learner control is seen as a major advantage of hypermedia for learning and instruction. For instance, learner control might increase students’ interest and motivation, facilitate adaptive instruction, or provide affordances for active and constructive information processing. In this paper we analyze the instructional potentials of learner-controlled hypermedia environments as well as possible reasons for the ambiguous results of studies that have aimed at determining the effectiveness of hypermedia learning. According to our analysis, the potential effectiveness of self-controlled learning with hypermedia might be difficult to demonstrate due to (1) usability problems (i.e., disorientation, distraction, cognitive overload), (2) moderating learner characteristics (i.e., prior knowledge, self-regulatory skills, cognitive styles, and attitudes towards learning), (3) a lack of conceptual foundations, and (4) methodological shortcomings of many hypermedia studies. The findings reviewed in this paper and the corresponding claim that hypermedia may be effective only if used in a sensible way are used to derive a couple of guidelines for further research on hypermedia learning.  相似文献

According to cognitive load theory, using worked examples is an effective and efficient instructional strategy for initial cognitive skill acquisition for novice learners, as it reduces cognitive load and frees up cognitive resources to build task competence. Contrary to this, productive failure (as well as invention learning, desirable difficulties and other problem-solving-first) frameworks suggest that scaffolded problem-solving activities (a generation phase) preceding explicit instruction enhance learners’ performance. The reported experimental study investigated the effectiveness of different levels of instructional guidance provided to students during the learning phase preceding explicit instruction in standard solution procedures in enhancing students’ engagement and transfer problem-solving skills. Specifically, the study compared partially-guided or unguided attempts at generating problem solutions as opposed to comprehensive guidance, in the form of a worked example. Levels of experienced cognitive load and learner motivation were evaluated in addition to delayed post-test performance scores. There were no differences between the three groups on the transfer post-test outcomes, even though the condition with fully-guided worked examples prior to the explicit instruction expectedly reduced cognitive load relative to the conditions without such guidance. There were also differences between the conditions on some sub-dimensions of the motivation scale. In general, the findings indicate that similar overall outcomes (delayed transfer performance) could be achieved by different sequences of instructional tasks aimed at achieving different sets of specific goals.  相似文献

Modern education emphasizes the need to flexibly personalize learning tasks to individual learners. This article discusses a personalized task-selection model with shared instructional control based on two current tendencies for the dynamic sequencing of learning tasks: (1) personalization by an instructional agent which makes sequencing decisions on the basis of learner’s expertise, and (2) personalization by the learner who is given control over – final – task selection. The model combines both trends in a model with shared instructional control. From all available learning tasks, an instructional agent selects a subset of tasks based on the learner’s performance scores and invested mental effort (i.e., system-control). Subsequently, this subset is presented to the learner who makes the final decision (i.e., learner control). A computer-assisted instructional program has been developed to put the model into practice and preliminary results are discussed. The model can be used to increase the efficiency and effectiveness of instruction and to make it more appealing by providing the learner an optimal level of control over task selection.

Abstract

This study examined the stability and change in secondary school students’ learner profiles after receiving an explicit strategy instruction (ESI) to foster their text-learning strategy use. A randomized quasi-experimental repeated measures design was set up with one experimental condition – receiving an eight-lesson-teacher delivered instructional treatment – and one control condition. Four learner profiles (i.e., integrated strategy users, information organizers, mental learners, and limited strategy users) were corroborated at three measurement occasions in a sample of 444 students. Cluster movement analysis identified positive changes in students’ learner profiles over time. Both short- and long-term results were promising.  相似文献

In Trinidad and Tobago, educational television is developed for the general secondary school population and is not generally designed to address specific learner needs. In this study, an instructional video production was developed and targeted to low-achieving students of the secondary school population, in the Junior Secondary sector. Content was drawn from the social studies curriculum and the focus of instruction was the acquisition of concepts and generalisations. There was sufficient evidence that the video production facilitated a moderate level of learning. It was also evident that there were areas of the production where instruction was not adequate. Two aspects were identified for further work. First, given the wide range of achievement levels noted in the current evaluation, there is need to identify more precisely the learning needs of the mainstream of the Junior Secondary population. Secondly, attention must also be paid to designing productions that could facilitate learner capability to link items of information and attain more complex levels of learning.  相似文献

The purpose of this study was to examine the effects of variations in lesson control and practice on the learning of facts, procedures, and problem-solving skills during interactive video instruction. Subjects were volunteers from graduate and advanced level undergraduate college classes. The instructional content was a 30-minute videotape. “Project Lifesaver,” which was designed to introduce cardiopulmonary resuscitation [CPR]. Students were randomly assigned to one of three instructional control groups: designer control, learner control, and linear control. A posttest was administered to assess learning of facts, procedures, and problem-solving skills. The results indicated that there were [1] significant differences between practiced and non-practiced information; [2] significant differences on posttest scores among various lesson control groups; and [3] a significant interaction between practice and type of learning.  相似文献

The authors examined the implementation of a blended learning program for literacy instruction across kindergarten through Grade 5 in a Title I urban elementary school, including a population of students (18%) who are English learners. Student progress in the online component of the blended learning program was a significant predictor of growth in reading performance on a standardized reading assessment (Group Reading Assessment and Diagnostic Evaluation, Pearson Assessment, Boulder, CO) when controlling for student grade level, initial student skill level, and English learner status; however, students in kindergarten through Grade 2 showed more substantial gains than students in later grades. These results suggest there is a benefit of a blended learning approach to literacy instruction for a diverse cross-section of students, particularly when beginning instruction in the early grades.  相似文献

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
