This article summarizes single-subject-design intervention studies that include students with learning disabilities. Effect sizes of 85 studies were analyzed across instructional domains (e.g., reading, mathematics); sample characteristics (e.g., age, intelligence); intervention parameters (e.g., number of instructional sessions, instructional components); and methodological procedures (e.g., internal validity, treatment integrity, sample representation). The major findings were as follows: (a) All domain areas except handwriting yielded effect sizes at or above Cohen's .80 threshold for a substantial finding; (b) instructional components related to drill-repetition-practice-review, segmentation, small interactive groups, and the implementation of cues to use strategies contributed significant variance (15%) to estimates of effect size; (c) strategy instruction (SI) models better predicted effect size estimates than direct instruction (DI) models when the results were qualified by the reported intellectual and reading levels of the participants; (d) high-IQ discrepancy groups yielded lower effect sizes compared to low-IQ discrepancy groups in the domain of reading, whereas the reverse effect occurred when treatment outcomes were not reading measures; and (e) the low-IQ discrepancy groups yielded higher effect sizes for a Combined DI and SI Model when compared to competing models. The results are supportive of the pervasive influence of cognitive strategy and direct instruction models across treatment domains and of the notion that variations in sample definition moderate treatment outcomes. 相似文献

An implication of the current research on self-regulation is to implement the promotion of self-regulated learning in schools.
Teachers can promote self-regulated learning either directly by teaching learning strategies or indirectly by arranging a
learning environment that enables students to practise self-regulation. This study investigates teachers’ direct and indirect
promotion of self-regulated learning and its relation to the development of students’ performance. Twenty German mathematics
teachers with their overall 538 students (grade 9) were videotaped for a three-lesson unit on the Pythagorean Theorem. Students’
mathematics performance was tested several times before and after the observed lessons. A low-inferent coding system was applied
to assess the teachers’ implicit or explicit instruction of cognitive strategies (e.g., organisation), metacognitive strategies
(e.g., planning), and motivational strategies (e.g., resource management). High-inferent ratings were used to assess features
of the learning environment that foster self-regulation. Results reveal that a great amount of strategy teaching takes place
in an implicit way, whereas explicit strategy teaching and supportive learning environment are rare. The instruction of organisation
strategies and some features of the learning environment (constructivism, transfer) relate positively to students’ performance
development. In contrast to implicit strategy instruction, explicit strategy instruction was associated with a gain in performance.
These results reveal a discrepancy between the usefulness of explicit strategy instruction and its rare occurrence in classrooms. 相似文献

“Formulation of instructional strategy to match subject matter and learner requirements” is an integral part of most instructional design models (Andrews & Goodson, 1980, p.5). Yet the meaning and purpose of instructional strategies in these design models vary considerably. An instructional strategy in traditional design models usually refers to the selection of instructional delivery vehicles (e.g., lecture, demonstration, computer-assisted instruction) and support activities (e.g., practice exercises, tutoring) (cf. Tracey, Flynn, & Legere, 1970). Contrast those conceptions with the many instructional strategies described in elaboration theory (Reigeluth & Stein, 1983), such as subsumptive sequencing, internally consistent orienting structures, synthesizers, summarizers, and cognitive strategy activators. What is obvious from these disparate conceptions is that instructional designers do not share a consistent definition of instructional strategies. Many of the activities that are referred to as instructional strategies are not in fact strategies, but rather are presentation vehicles. In this article, we first define instructional strategies and tactics in the context of an iterative design model. Instructional strategies are then distinguished from instructional tactics, which are the implementation of strategies. We then list the range of instructional strategies and tactics that implement them. Finally, we provide a decision tree for assisting designers to select appropriate instructional tactics. 相似文献

Spoken words have always been an important component of traditional instruction. With the development of modern educational technology tools, spoken text more often replaces or supplements written or on-screen textual representations. However, there could be a cognitive load cost involved in this trend, as spoken words can have both benefits and disadvantages based on essential characteristics of our cognitive architecture. This paper analyzes factors that might moderate the effectiveness of using spoken text in instruction by reviewing relevant studies in multimedia learning and considering cognitive load consequences of the transiency of spoken information. However, in contrast to earlier studies that considered spoken words in the context of a specific cognitive load effect, this paper provides a framework for evaluating potential instructional benefits of spoken text by analyzing various instructional situations depending on whether spoken text is used together with pictures and written text, and taking into account relations between presented sources of information. 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

This article is based on the premise that instruction involves the control of cognitive processes by means of carefully selected
instructional strategies. Visual cognitive processes having to do with perception, the assimilation of new information, and
learning by means of analogy are examined, and particular instructional strategies by which each process can be controlled
are identified. Ways of improving mental skills (i.e., those visual processes at which the learner is relatively adept) are
discussed. Conclusions are drawn regarding relationships between visual learning and instruction, and implications for research
and design are examined.

ABSTRACT This article reports on an intervention study into the effects of a training in the use of social and cognitive strategies on the learning outcomes of students in secondary mathematics education. Special attention is given to differential effects for high‐ and low‐achieving students. The focus on differential effects is derived from studies into learning in small co‐operative groups, and from the results of meta‐analyses into the effects of training in learning strategies. From these studies it can be concluded that in general such programs contribute to learning. However, it seems that low‐achieving students are unable to benefit from interventions of the kind investigated (i.e., co‐operative learning and training in learning strategies). The main question is whether it is possible to design an instructional program from which all students benefit, and from which the low‐achieving students profit more than their counterparts in the control‐program. In the present study three instructional programs for co‐operative learning were compared: (i) an experimental program with special instruction in the use of social strategies; (ii) an experimental program with special instruction in the use of cognitive strategies; and (iii) a control program without training in either cognitive or social strategies. The programs were identical with respect to mathematical content and general instructional settings (a combination of whole‐class instruction, working in co‐operative groups and individual work). The experiment addressed the following research question: what are the general and differential effects of a training in the use of social and cognitive strategies on the results of learning in secondary mathematics? The research was conducted in two schools for secondary education in a total of 21 classes, involving a total of 511 students. The design was a pretest‐posttest control group design, using two experimental groups and one control group. The data were analysed from a multi‐level perspective. The outcomes of the investigation clearly show the effects of the intervention. Teaching cognitive and social strategies has the expected, positive effects. In addition to this main effect, a compensatory effect for the low‐achieving students was found. The low‐achieving students in the experimental conditions outperformed their counterparts in the control group. 相似文献

Students with mathematics learning disabilities (LD) exhibit difficulties with retrieval and cognitive skills that impede their ability to perform basic mathematical skills. Instruction in mathematical procedures (i.e., procedural knowledge) is necessary to help students learn and apply skills such as basic facts and whole-number computation. Division is a skill that is identified in curriculum across the grade levels; yet, it is a skill that is often taught last in instructional sequences because of its complexity and prerequisite knowledge. Reviews of research have revealed that students with LD benefit from a combined model of academic instruction that includes both explicit and strategic instructional procedures. This article presents an overview of division instruction and a sample of interventions for teaching division that include explicit and strategic instructional procedures, which are found in the combined model of teaching. 相似文献

Systematic instructional strategies that investigators have used with students who display moderate to severe handicaps were identified and defined. The investigations which directly compared two or more strategies were analyzed, and summary statements/recommendations about the relative effectiveness and efficiency of the strategies were made. Analyzing the effectiveness of the procedures involved determining which strategies successfully taught skills to subjects. The efficiency of the strategies was analyzed on measures which indicated the skills were taught in a productive and timely manner (i.e., trials to criterion, sessions to criterion, errors to criterion, direct instruction time). Recommendations for future research and practice include (a) conduct more studies comparing the effectiveness and efficiency of instructional strategies, (b) conduct investigations of the specific variables of single strategies to identify the most efficient use of each procedure, (c) expand the efficiency measures to assess whether students learn information not directly targeted for instruction, and (d) conduct research to determine which strategy is best to use with given types of students and skills. 相似文献

To become competent professionals, students should work on both their strengths and weaknesses. Considering students' limited amount of time and energy to work on multiple subjects, it is important to know what determines their allocation of effort to their perceived relative strengths or weaknesses. In a series of five studies, we examined the moderating effect of instructional strategy (i.e., self-directed versus test-directed) on the within-person relation between perceived relative strength (i.e., strengths versus weaknesses) and allocated effort across multiple subjects. We used different methodologies (scenario, field, and experimental studies), research designs (within-person and mixed factorial), populations (secondary school, college, and university students), and measures of effort (intentions, self-reported, and behavioral). The results consistently indicate that students in a self-directed instructional strategy condition tend to allocate more effort to their relative strengths, whereas students in a test-directed instructional strategy condition tend to allocate more effort to their relative weaknesses. 相似文献

This article presents a critical review and analysis of key studies that have been done in science education and other areas
on the effects and effectiveness of using diagrams, graphs, photographs, illustrations, and concept maps as adjunct visual aids in the learning of scientific-technical content. It also summarizes and reviews those studies that have students draw diagrams,
graphs, maps, and charts to express their understandings of the concepts and relationships that are present in the text they
read or/and empirical data provided (i.e., student-generated adjunct visual productions). In general, the research and theory on instructional aids is fragmented and somewhat unsystematic with several flaws and
a number of key uncontrolled variables, which actually suppress and mask effects in the studies that have been done. The findings
of these studies are compared to relevant literature and empirical research and findings in the areas of cognitive psychology,
computer science, neuroscience, and artificial intelligence that help to clarify many of the inconsistencies, contradictions,
and lack of effects found for visual (e.g., diagrams and graphs) instructional aids in the science education literature currently
and in the past 20 years. A model and a set of criteria and goals for improving research in this area is then described, as
visuals are a first step in the process of learning formal (scientific) models, which are most often visually represented.
Understanding how students learn formal models is one the outstanding research challenges in the next 20 years, both within
and outside of science education. 相似文献

The present article provides a meta-analysis of instructional research with samples of children and adolescents with learning disabilities in the domains of word recognition and reading comprehension. The results of the synthesis showed that a prototypical intervention study has an effect size (ES) of .59 for word recognition and .72 for reading comprehension. Four important findings emerged from the synthesis: (a) Effect sizes for measures of comprehension were higher when studies included derivatives of both cognitive and direct instruction, whereas effect sizes were higher for word recognition when studies included direct instruction; (b) effect sizes related to reading comprehension were more susceptible to methodological variation than studies of word recognition; (c) the magnitude of ES for word recognition studies was significantly related to samples defined by cutoff scores (IQ > 85 and reading < 25th percentile), whereas the magnitude of ES for reading comprehension studies was sensitive to discrepancies between IQ and reading when compared to competing definitional criteria; and (d) instructional components related to word segmentation did not enter significantly into a weighted least square hierarchical regression analysis for predicting ES estimates of word recognition beyond an instructional core model, whereas small-group interactive instruction and strategy cuing contributed significant variance beyond a core model to ES estimates of reading comprehension. Implications related to definition and instructional components that optimize the magnitude of outcomes are discussed. 相似文献

ABSTRACT The effect of instructional materials enhanced with textual metaphors versus graphical metaphors was investigated. In the text‐plus‐textual metaphor material, the learning content described computer programming logic patterns (i.e. sequence, selection and repetition control structures) in a generic text format, followed by expository examples in the form of textual metaphors. The text‐plus‐graphical metaphor material consisted of the generic text instruction with the expository examples replaced by graphical metaphors (pictures). A total of 37 adult learners attended one lecture and two tutorials to learn how to write programming algorithms. All of the participants completed Riding and Cheema's (1991) Cognitive Styles Analysis (CSA) to measure their position on two cognitive style dimensions: Wholist‐Analytic and Verbal‐Imagery. The participants were paired based on their similar CSA ratios. One participant from each pair was given the text‐plus‐textual metaphor treatment, while the other was given the text‐plus‐graphical metaphor treatment. The treatment groups were controlled for instructional format and cognitive style. These independent variables were used to test for their effect on learning abstract computer programming concepts. Performance, as measured by the difference between pre‐test and post‐test scores, was analysed using statistical means and the QUEST probability analysis program. Both methods show that graphical metaphors improve participants’ performance. They also show that the best performance is achieved by Verbalisers, given the graphical metaphor instructional material. 相似文献

This study examines the relationship between characteristics of academic areas and students' evaluation of instruction. Based on Biglan's model of subject matter and relevant studies of the role of instruction, a weak partial order model for classifying academic fields and predicting their relative ranking on instructional evaluation was tested. The findings of the study support the weak partial order model for all three criteria of instructional evaluation that are used in this research. Moreover, the major discriminant facet in this study is the knowledge base of the academic program (i.e., hard versus soft sciences). Based on the results of this research, an adapted model for understanding the role of academic areas in predicting instructional evaluation is proposed. The implications of this study are discussed and elaborated. 相似文献

The current study examined special education teachers' ratings of the usefulness of strategy microanalytic assessment (SMA) (i.e., self‐regulation, strategy use) and standardized norm‐referenced assessment information (SNRA) (i.e., cognitive and academic skills). Ninety‐six participants separately rated the frequency with which SMA and SNRA are used in schools and the usefulness of each report [i.e., Teacher Rating Questionnaire (TRQ)] for intervention planning about a case study. A mixed model experimental design revealed that even though SNRA information is more typical of the data provided in evaluation reports/Individualized Educational Programs, the SMA data were rated significantly more helpful than the SNRA for enhancing important school‐related outcomes (e.g., test performance) as well as teacher‐related roles (e.g., developing instructional plans). Despite the participants' consistent preference for SMA information, their overall TRQ ratings of the SNRA were positive. © 2006 Wiley Periodicals, Inc. Psychol Schs 43: 149–155, 2006. 相似文献

A manipulation of the instructions students received prior to completing the 7-item Endeavor Instructional Rating card differentially affected their ratings on two types of items. Specifically, when students were led to believe their ratings would have a strong impact on the instructor's career, they tended to be more lenient on items measuring rapport (i.e., the affective domain); this same effect was not observed for items measuring pedagogical skill (i.e., the cognitive domain). The different items on our instructional rating instrument appear to be measuring different things. One implication of this observation is that the inconsistent findings reported in past research on student ratings of instruction may be due to the differential mix of items from one instrument to another. When instructors are compared on ratings given them by students, unbiased interpretation requires that the multidimensional nature of teaching (and of the rating instrument) be considered. 相似文献

Drawing on the Documents Model Framework, in two studies we investigate the types of multiple text models (e.g., mush model, separate representations model, documents model) reflected in students’ written responses, composed based on multiple texts. In among the first studies to holistically code written responses for the type of multiple text models they reflect, we find evidence for all of the multiple text representations specified in the Documents Model. We further examine the types of integration, or cross-textual connections, featured in students’ responses, including evidentiary (i.e., corroborating evidence), thematic (i.e., comparing main ideas across texts), and contextual (i.e., comparing meta-textual information, like author expertise) connections. Finally, we associate the types of multiple text models reflected in students’ written responses with various measures of integration, including the number of discourse connectives and citations included and self-reports of strategy use (Study 1), as well as with integrative utterances reported during a cued think-aloud (Study 2). 相似文献

教学效率数学模型建构的教育原理及意义 总被引：1，自引：0，他引：1
查有梁 《现代远程教育研究》2012,(4):3-8
如何提高教学效率,是各层次各类教学研究的重要问题。在教学理论和实践基础上首次提出的“教学效率的数学模型”,可以直观地理解教学效率的三个限制性原理,即在学校教育中不能仅仅强调学生自主学习,不能仅仅强调教师单向传授知识,教与学是相互“耦合”的。其原理表明三个不可能：只要求学生自主学习,不可能高效;只要求教师灌输,不可能高效;不将教师的教学转化为学生的自学,不可能高效。以此模型推论,对于不同学科、不同水平的教师和学生,两条“学历一效率”曲线的交点0是不同的。这就为因材施教地研究教学效率提供了新思路。在系统研究教学模型基础上建构的“教学模型的数学模型”,是“模式的模式”,即元模式。元模式的研究具有方法论价值,为教师在教学中选择合适的教学模型提供了实用的模式“网络结构”。这些数学模型之于远程教育的意义是：远程教学十分需要新的突破。 相似文献
