In science classes, teachers must consider the need for explicit, systematic reading instruction for students with learning disabilities (LD) while navigating the constructivist and activity‐oriented methods typically employed in science instruction. The complexity of scientific information conveyed through print may make reading science texts the greatest challenge that students with LD encounter in school. Fortunately, researchers have established that, by fostering students’ prior knowledge, providing text enhancements, and teaching reading comprehension strategies, students’ understanding of science text is improved. Effective instructional approaches and strategies for reading are reviewed and implications for teaching students with LD noted.  相似文献

Fractions are an essential foundational skill for future mathematics success (NMAP, 2008). The purpose of this article was to review current instructional practices for teaching fractions to struggling learners and to examine the quality and effectiveness of contemporary research with a view to indicating directions for future research. A comprehensive search of literature published between 1990 and 2008 resulted in the identification of 10 empirical studies that targeted fraction skills for struggling learners. Results indicated that three interventions, found to be effective for improving outcomes in mathematics for struggling learners, were also effective for teaching fractions: graduated sequence, strategy instruction, and direct instruction. In addition, explicit instruction was identified as necessary for improving students’ performance in fractions. Overall, this review highlighted the paucity of research in this critical mathematical content area.  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

ABSTRACT

In theory, both virtual manipulatives and explicit instruction are viable options to support students with disabilities as they learn mathematics. This study explored the effect of a treatment package—an app-based virtual manipulative (Cuisenaire® Rods) in conjunction with explicit instruction—on students’ acquisition and generalization of solving problems involving division of whole numbers with remainders. Three middle school students with disabilities participated in this multiple baseline, multiple probe across participants single case design study. Each of the students acquired the mathematical behavior of being able to solve division with remainders problems. In other words, a functional relation existed between the intervention package of explicit instruction and the Cuisenaire® Rods app-based manipulative and students’ accuracy in solving division with remainders problems. Yet, two students failed to generalize the skill without the explicit instruction and use of the app-based manipulative.  相似文献

Adults with learning disabilities (LD) attending adult basic education, GED programs, or community colleges are among the lowest performers on measures of literacy. For example, on multiple measures of reading comprehension, adults with LD had a mean reading score at the third grade level, whereas adults without LD read at the fifth grade level. In addition, large numbers of adults perform at the lowest skill levels on quantitative tasks. Clearly, significant instructional challenges exist for adults who struggle with literacy issues, and those challenges can be greater for adults with LD. In this article, the literature on adults with LD is reviewed, and evidenced-based instructional practices that significantly narrow the literacy achievement gap for this population are identified. Primary attention is given to instructional factors that have been shown to affect literacy outcomes for adults with LD. These factors include the use of explicit instruction, instructional technology, and intensive tutoring in skills and strategies embedded in authentic contexts.  相似文献

Improving the comprehension of disabled readers   总被引：1，自引：1，他引：0  
Students with learning disabilities (LD) often have difficulty comprehending what they read. Although reading comprehension problems frequently are associated with inadequate word recognition, students also have difficulties related to comprehension itself—a passive approach to the reading task, insensitivity to text structure, and poor metacognitive skills. The reading and language arts curricula that have emerged from today’s constructivist paradigm can pose problems for these students. Whereas the new curricula emphasize personal interpretations of text and relatively unstructured teaching strategies, students with LD do well with explicit, highly structured instruction. This paper introduces an instructional program designed to teach students with serious learning disabilities how to identify a story theme, and how to relate it to their own real-life experiences. The program focused on understanding a text as a whole, and integrating text meaning with concepts and experiences that are personally meaningful, goals shared by a constructivist approach. At the same time, the program incorporates the explicit, structured instruction that these students also need. A study to evaluate the program’s effectiveness is described, as are current efforts to refine the program to promote transfer of comprehension strategies.  相似文献

ABSTRACT

Graduate students regularly teach undergraduate STEM courses and can positively impact students’ understanding of science. Yet little research examines graduate students’ knowledge about nature of science (NOS) or instructional strategies for teaching graduate students about NOS. This exploratory study sought to understand how a 1-credit Teaching in Higher Education course that utilised an explicit, reflective, and mixed-context approach to NOS instruction impacted STEM graduate students’ NOS conceptions and teaching intentions. Participants included 13 graduate students. Data sources included the Views of Nature of Science (VNOS-Form C) questionnaire administered pre- and post-instruction, semi-structured interviews with a subset of participants, and a NOS-related course project. Prior to instruction participants held many alternative NOS conceptions. Post-instruction, participants’ NOS conceptions improved substantially, particularly in their understandings of theories and laws and the tentative nature of scientific knowledge. All 12 participants planning to teach NOS intended to use explicit instructional approaches. A majority of participants also integrated novel ideas to their intended NOS instruction. These results suggest that a teaching methods course for graduate students with embedded NOS instruction can address alternative NOS conceptions and facilitate intended use of effective NOS instruction. Future research understanding graduate students' NOS understandings and actual NOS instruction is warranted.  相似文献

Englert and her colleagues have contributed much to our knowledge about effective writing instruction. They have demonstrated that interventions that make explicit the writing process and text structures are successful with students with learning disabilities as well as those without. Englert attributes this success to the holistic, social, and interactive nature of the instruction. However, one must keep in mind that CSIW was a package approach that included other validated instructional components. CSIW teachers presented conceptual models, used examples and nonexamples to illustrate text structure concepts, modeled thinking overtly while demonstrating the process, provided guided practice by prompting the process through dialogue and think-sheets, faded prompts as students took over more of the responsibility for the process, and taught for generalization by addressing more than one text structure and promoting student talk about the process. As Englert reported, most teachers seldom do these things, even when they claim to teach the writing process. Englert allows for the possibility that all students with learning disabilities may not be ready for cognitive strategy instruction as it is described in her article, and professionals must acknowledge that different techniques may be more effective for students of different ages and abilities. Swanson (1990) emphasized that there must be a match between strategy and learner characteristics and that strategies must be considered in relation to a student's knowledge and capacity. Strategic teaching requires that the teacher have a repertoire of approaches along a continuum that encompasses coaching students to use their own mental resources at one end and basic skill instruction at the other.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

Research Findings: This study investigates the role of fine motor and mathematics instruction in mathematics achievement in an international sample of kindergarteners from the United States and China. Multilevel modeling was used to assess the interaction between students’ entering skills and classroom time spent on basic math, higher-order math and fine-motor instruction. For American children, the effect of basic math and higher-order math instruction on student achievement depended on entering skills; however, fine motor instruction had negative average effects on student achievement and did not depend on students’ entering skills. Instruction time was not a significant predictor of achievement for Chinese students. Practice or Policy: Though fine motor skills have a robust correlation with mathematics achievement, a causal link has not been established. Our study indicates that time spent in fine motor instruction does not advance mathematics achievement in kindergarten and in fact may weaken mathematics achievement, given the limited time in the instructional day. American teachers in our sample who spent more time in fine-motor instruction tended to spend less time on basic math and higher-order mathematics instruction. Educators should weigh instructional trade-offs carefully and work to tailor instruction to students’ skill levels.  相似文献

Numerous researchers have suggested that there are multiple mathematical knowledge and skill areas needed by teachers in order for them to be effective teachers of mathematics: knowledge of the mathematics that are the goals of instruction, advanced mathematics beyond the instructional material, and mathematical knowledge that is specific to what is needed to teach students. The research reported here is about the development of a test of teachers’ knowledge in these three areas related to the teaching of algebra. The test development process is described and the results of several analyses are reported that had the goal of checking whether valid inferences can be made about the hypothesized components of teacher knowledge.  相似文献

This article chronicles the evolution of a programmatic line of research on strategic writing instruction for adolescents with learning disabilities (LD) conducted by staff and affiliates of the University of Kansas Center for Research on Learning. The goal associated with this research is that students with LD learn the writing skills that they need to succeed in high school and beyond and that their skills are comparable to the skills of their peers. Individual studies have shown that adolescents with LD can master a given writing strategy and can apply that strategy to novel prompts and in general education classes. Moreover, they can learn simple writing strategies from computerized programs. They can also maintain use of a writing strategy over time. When students learn several writing strategies, their scores on standardized tests improve, and their writing competency is comparable to that of peers. Studies have also shown that teachers can teach the writing strategies and achieve successful results. Care must be taken, however, to ensure that students with LD receive the instruction under conditions where they have multiple opportunities to reach mastery on each skill and receive individualized feedback on practice attempts. Overall, the research has shown that adolescents with LD can learn complex writing skills such as planning, writing, and editing multiparagraph themes; can apply these skills to tasks that are assigned in required general education courses; and can be successful in those courses.  相似文献

The Common Core Standards require demonstration of conceptual knowledge of numbers, operations, and relations between mathematical concepts. Supplemental instruction should explicitly guide students with specific learning disabilities (SLD) in these skills. In this article, we illustrate implementation of the concrete‐representational‐abstract (CRA) sequence and the Strategic Instruction Model (SIM) for teaching multiplication with regrouping to students with SLD. CRA combined with SIM has been shown to be effective in teaching computation for students with SLD, specifically for developing conceptual understanding. Four elementary students with SLD participated in this study. The researchers used a multiple‐probe design to show a functional relation. Students demonstrated increases in computational fluency; skills were maintained and generalized.  相似文献

This study explores the impact of ‘Scientific Communication’ (SC) skills instruction on students’ performances in scientific literacy assessment tasks. We present a general model for skills instruction, characterized by explicit and spiral instruction, integration into content learning, practice in several scientific topics, and application of performance tasks. The model was applied through an instructional program that focuses on the following learning skills: information retrieval, scientific reading and writing, listening and observing, data representation, and knowledge presentation. Throughout the 7th–8th grades, 160 students learned the whole program or one of its components: structured instruction (SI) of SC skills, or performance tasks (PT). A comparison group of 42 students did not receive instruction of SC skills. Students’ performances were assessed through a questionnaire and a complex task that measured students’ scientific content knowledge, SC skills, and the quality of the final products. Results indicated that students who learned the whole program or one of its components achieved higher scores in all categories than the comparison group students. High achievers can benefit from just one component of the program: either structured instruction (SI) or learning from practice (PT). However, they can hardly acquire SC skills spontaneously. Low and average achievers require both components of the SC program to improve their performances. Results show that without planned intervention, the spontaneous attainment of SC skills occurs only to a limited extent. Systematic teaching of skills can make a significant difference. The explicit instruction of skills integrated into scientific topics, the opportunities to implement the skills in different contexts, the role of performance tasks as ‘assessment for learning’—all these features are important and necessary for improving students’ scientific literacy. Our general model of skills instruction can be applied to the instruction of other high-order skills. Its application can lead to the realization of the central goal of science education: literate students possessing scientific knowledge.  相似文献

The passage of No Child Left Behind and the Individuals with Disabilities Education Act has strengthened the conditions for instructional accountability for all learners. The standards‐based approach promulgated by curriculum and state assessments is central to the accountability of conditions in today's schools; however, national and state data continue to document a performance gap between students with learning disabilities (LD) and their nondisabled peers. Building on 5 years of experience in developing and testing the Blending Assessment with Instruction Program in mathematics, we present three basic principles that are essential to ensuring that students with LD achieve curriculum standards: (1) instruction must be aligned with curriculum standards, (2) teachers' content knowledge is essential to translating curriculum standards into aligned instruction, and (3) instructional methodology should receive greater attention during teacher preparation.  相似文献

Experimental skills should be acquired by learners at school and university alike. To promote experimental skills, various approaches exist within a spectrum between implicit and explicit instruction. Regarding these instructional approaches, numerous findings are available which predominantly relate to pupils. It is an open question whether it is better to instruct experimental skills explicitly or implicitly in university courses. And if experimental skills are fostered explicitly, what about the content-related skills? Especially in teaching programmes with both experiment-related and content-related objectives, it is questionable whether content-related objectives are achieved to a lesser degree via explicit instruction of experimental skills. Both questions are addressed in this paper. We present an intervention study involving 144 students. All students carry out the same experiments. The intervention groups differ merely in the degree of explicit instruction. Learning gains in experimental and content-related skills are assessed in a pre-/post-test design. The results show that the type of instruction does not significantly influence the acquisition of experimental and content-related skills in this target group. But by trend, the expected differences in learning gains can be observed. This leads to new research perspectives and implications for teaching which are discussed.  相似文献

Extensive evidence has suggested mathematical skill in early childhood is a robust predictor of children's later academic skills and eventual labor market outcomes; however, there is substantial heterogeneity in the degree to which different students learn from the same instructional contexts. Using data from N = 12,082 children enrolled in the Early Childhood Longitudinal Study-Kindergarten Cohort, this paper employs a latent piecewise growth curve modeling approach to investigate the role of classroom math instruction and executive function and approaches to learning in the development of mathematical skills in kindergarten, first, and second grade. Findings suggest that overall instructional frequency relates to math development in kindergarten through second, and that this is driven by exposure to advanced content in kindergarten. Further, executive function moderates children's learning in kindergarten, such that children with higher levels of executive function benefit more from instruction than do those with lower levels.  相似文献

In an attempt to demonstrate the effectiveness of instructional programming in counseling, an experimental evaluation of a ten-week program aimed at teaching skills and strategies of self-instruction to high school students was conducted. Thirty-two grade ten students were assigned randomly to an experimental self-instruction group and a control group. Dependent variables included Rotter's (1966) Control of Reinforcement Questionnaire, Rosenbaum's (1980) Self-control Schedule, a curriculum-specific test of self-instruction concepts, and a transfer test. Results revealed that students in the experimental, self-instruction program outperformed students in the control group on all dependent variables except for the Self-control Schedule. Content analysis of student responses to the transfer test showed a distinct pattern of skill development in the experimental group from pretest to posttest. Implications for the development and offering of instructional counseling programs are drawn.Many students of counseling have argued that counseling is essentially a kind of teaching (Carkhuff and Berenson, 1976; Ellis, 1977; Katz and Ivey, 1977; Krumboltz and Thoresen, 1976; Sorenson, 1967). More recently, Martin and his colleagues have developed an approach to counseling that employs models of instruction as a basis for the development and implementation of a broad range of counseling interventions and programs (Hiebert et al., 1981; Martin and Hiebert, 1982; Martin et al., 1981; Martin et al., 1980). Martin (1983) also has suggested that counselors in schools and elsewhere can make use of systematic teaching programs to help clients/students acquire functional skills in a variety of areas such as anxiety management, decision making, interpersonal skills, and so forth. In the development and offering of such programs, counselors act as curriculum developers and instructors. Initial evidence for the viability of this type of instructional counseling in schools was provided by Haynes et al. (1983), and Leal, Baxter, Martin, and Marx (1981) who developed programs based on cognitive and behavioral counseling methods that were successful in alleviating the test anxieties experienced by high school students. The experiment reported here extends the work of Martin and others in instructional counseling by evaluating an instructional program designed to teach a series of integrated skills of self-instruction to high school students. [Note that the term self-instruction is used here to refer to the activities of people engaged in systematic self-change, and is not intended to connote the system of self-instruction training developed by Donald Meichenbaum (1977).]Nearly all teachers and curriculum specialists share at least one goal: to help students acquire the capacity to engage in self-directed learning. Most often, it is assumed that school students will acquire skills in areas such as self-instruction and critical thinking (skills often seen as necessary requisites to self-directed learning) as a result of stimulating interactions with traditional school curricula. A frequently voiced alternative is to attempt to teach such skills directly (cf. Beyers, 1984a, 1984b), more or less as a curriculum in their own right. Many attempts have been made to do this, but few have received detailed empirical, experimental analysis. In a recent meta-analysis of primary prevention studies conducted in schools, Baker, Swisher, Nadenichek, and Popowicz (1984) found 40 such studies that had been conducted since 1970. Most of the experimental programs in the studies reviewed were targeted at improving students' communication skills, decision making and problem solving skills, and self-awareness. None of the studies reviewed by Baker et al. included instructional interventions that attempted to teach a broad range of skills and strategies that would permit students to plan, implement, and evaluate programs of personal change and development. Teaching school pupils to engage in systematic self-instruction for purposes of personal change simply has not been attempted, to date, in the context of an experimentally controlled investigation. Given an increasing number of pleas for exactly this kind of broad-based school programming (Martin, 1983; Sprinthall, 1984), the need for controlled experimental studies in this area is acute.Self-introduction or learning to learn has been the subject of considerable theorizing by both cognitive and instructional psychologists (Gagné, 1977; Bransford, 1979). Experimental work by Ann Brown and her colleagues (Brown, 1978; Brown et al., 1979) has highlighted the difficulty of teaching various metacognitive strategies that would seem basic to the capacity to self-instruct so as to ensure the transfer of such strategies to tasks other than those employed during strategy acquisition. At the same time, Brown's research also shows that the teaching of generalizable metacognitive strategies such as self-testing is possible, even with educable retarded children (Brown, et al., 1979). Other research concerned with differences between expert and novice knowledge has highlighted the importance of the ability to access declarative knowledge stores and the availability of relevant procedural knowledge in attempting to explain these differences (Chi et al., 1982; Leinhardt, 1983). [See Anderson, (1980) for formal definitions and discussions of declarative and procedural knowledge.] The greater ability of experts to function as independent learners or self-instructors in their areas of expertise likely is related to such differences. While it sometimes is unclear as to whether self-instructional competence resides in procedural knowledge stores or cognitive and/or metacognitive strategies, it seems clear that learning to learn involves more than simply acquiring necessary declarative knowledge in relevant substantive areas (Glaser, 1984). Thus, explicit, direct instruction in skills and strategies of self-instruction probably is necessary if students in schools are to learn to direct their own learning and development.The experiment reported here was conducted to supply initial experimental data about the possible effectiveness of a program designed to teach skills and strategies of self-instruction to high school students. It is a study of a ten-week instructional counseling program developed to teach self-instruction skills in areas such as decision making, gathering information, self-assessment, framing objectives, planning, and self-evaluation. As such, it is a more comprehensive program than other programs of primary prevention in schools that have been studied experimentally. While a variety of school and extracurricular situations were employed as illustrative contexts for presenting information about these skills to the students, the goal of the experimental program was to teach the self-instruction skills as detached skills that could be applied to a variety of situations and life circumstances. This approach was viewed as contrasting with traditional approaches in which such skills are thought to be acquired indirectly as a result of working through a series of tasks in defined substantive areas such as mathematics, history, or physics. In this latter method, it is likely that such skills, if they are acquired, become embedded in specific substantive contexts and are therefore less likely to generalize to situations or contexts other than those in which they were acquired (see Rigney, 1978 for the distinction between detached and embedded strategies). Dependent variables employed in the study were selected to test for the acquisition and transfer of targeted skills as well as for the acquisition of underlying beliefs about one's ability to control or influence external and internal events. The latter type of learning is thought by many counselors to be of great importance, particularly if attitudes and beliefs are learned that affect clients' attributional styles and/or tendencies (Strong and Claiborn, 1982).The overall purpose of the experiment was to determine whether instructional counseling curricula could be developed that would succeed in teaching detached strategies/skills of self-instruction to high school students. Should such instruction be possible, additional support would be provided for the notions of instructional counseling and counselors as curriculum developers and instructors. After all, a major part of counseling typically is associated with assisting clients to make decisions, gather information, frame goals and objectives, assess their situations and capabilities, plan actions, and evaluate the effects of their actions—all components of the self-instruction program taught to the experimental students in this study.The specific hypotheses investigated were that participation in the experimental instructional counseling program would increase: 1) students' knowledge of self-instruction skills (acquisition learning), 2) students' abilities to apply this knowledge to everyday events (transfer learning), and 3) students' attitudes consistent with higher levels of self-control and internal attributional processes (general attitudinal learning).The research reported here was supported by a grant from the Chairpersons' Research Fund, Simon Fraser University.The authors gratefully acknowledge the assistance of Bruce Dallin, Louise Bourassa, Olwyn Irving, David Langton and the Abbotsford School District (British Columbia, Canada) in completing this work.  相似文献

In this study, 12 pre-service mathematics teachers worked in teams to develop their knowledge and skills in using teacher-led spreadsheet demonstrations to help students explore mathematics concepts, stimulate discussions and perform authentic tasks through activity-based lessons. Pre-service teachers’ lesson plans, their instruction of the lessons designed, experiences and lesson enactment outcomes were examined. The pre-service teachers in the study were able to develop and demonstrate their knowledge and skill adequately in designing and enacting activity-based mathematical lessons supported with spreadsheets. The results also showed that the pre-service teachers’ use of the spreadsheet as an instructional tool promoted student in-depth mathematical concept formation and an activity-based learning approach to make lessons less teacher centred and more interactive.  相似文献

The purpose of the present study is to examine the effects of IMPROVE, a meta-cognitive instructional method, on students' mathematical knowledge, mathematical reasoning and meta-cognition. Participants were 81 students who studied a pre-college course in mathematical. Students were randomly assigned into one of two groups and groups were randomly assigned into one of two conditions: IMPROVE vs. traditional instruction (the control group). Both groups were exposed to the same learning materials, solved exactly the same mathematical problems, and were taught by the same experienced teacher. The IMPROVE students were explicitly trained to activate meta-cognitive processes during the solution of mathematical problems. The control group was exposed to traditional instruction with no explicit exposure to meta-cognitive training. Results indicate that the IMPROVE students significantly outperformed their counterparts on both mathematical knowledge and mathematical reasoning. In addition, the IMPORVE students attained significantly higher scores then the control group on the three measures of meta-cognition: (a) general knowledge of cognition; (b) regulation of general cognition; and (c) domain-specific meta-cognitive knowledge. The theoretical and practical implications are discussed.  相似文献
