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

Our study compared the learning and motivational outcome of one educational approach in two different learning environments, a natural science museum and a classroom, drawing on studies about the effects of field trips on students’ learning and motivation. The educational intervention consisted of an introduction phase in the classroom and subsequent learning at workstations, either in the museum or the classroom. 190 secondary school students participated in the quasi-experimental design. We assessed knowledge and understanding by using a pre-, post- and retention-test design, and applied subscales of the ‘Intrinsic Motivation Inventory’ to consider motivational aspects. Students of the museum-group learnt more compared to the classroom-group, whereas motivation differed only in one subscale of the motivation test, with higher scores for the museum-group. Results are discussed in terms of the overall added value of field trips for school curricula.  相似文献

The study examined the use of a conceptual and procedural framework for identifying math deficits and delivering appropriate interventions. Participants were two first‐grade students and one third‐grade student, who were identified as struggling with the grade‐appropriate content in math. The first‐grade students focused on addition and the third‐grade student focused on multiplication. Each student's conceptual understanding was assessed, and students who lacked conceptual understanding received an intervention that addressed underlying concepts. Students with acceptable understanding of the underlying concepts received an intervention that focused on the procedure. The study used a single‐case, multiple‐baseline design, but the contra‐indicated intervention was administered for the first 2 weeks following baseline, with the prescribed intervention for the final 2 weeks. Each student showed more growth during the prescribed intervention phase when compared to the contra‐indicated phase.  相似文献

In many life science classrooms, instructors rely upon lecture presentations to efficiently present course content. Students, in this case, act as passive learners with little opportunity to test their knowledge for gaps or misconceptions. The goal of the project described here was to determine whether a collaborative quiz protocol that guided students to discuss their understanding with their peers would improve learning and academic performance. The project took place during a single semester and was composed of two studies: a preliminary study that incorporated short-answer quizzes into the curriculum and a comprehensive study that incorporated short-answer quizzes and justify/explain quizzes in which students were expected to select an answer and then justify or explain it. Students took all quizzes twice, first independently and then collaboratively with classmate(s). Learning was assessed using multiple-choice exam questions based upon quiz topics. Students scored significantly higher on exam questions associated with justify/explain quiz topics than on those associated with short-answer quiz topics.  相似文献

Abstract. Thirty‐four matched pairs of sixth‐ and seventh‐grade students were selected from 358 participants in a comparison of an explicit concrete‐to‐representational‐to‐abstract (CRA) sequence of instruction with traditional instruction for teaching algebraic transformation equations. Each pair of students had been previously labeled with a specific learning disability or as at risk for difficulties in algebra. Students were matched according to achievement score, age, pretest score, and class performance. The same math teacher taught both members of each matched pair, but in different classes. All students were taught in inclusive settings under the instruction of a middle school mathematics teacher. Results indicated that students who learned how to solve algebra transformation equations through CRA outperformed peers receiving traditional instruction on both postinstruction and follow‐up tests. Additionally, error pattern analysis indicated that students who used the CRA sequence of instruction performed fewer procedural errors when solving for variables.  相似文献

Abstract. This study investigated the effects of teaching middle school students with mathematics disabilities equivalent fraction concepts and procedures using the concrete‐representational‐abstract (CRA) instructional sequence or the representational‐abstract (RA) instructional sequence. Twenty‐six students formed the CRA group, and 24 students formed the RA group. The two treatment groups received carefully sequenced instruction over 10 lessons. The only difference between the two treatment groups was that the CRA group used concrete manipulative devices for the first three lessons while the RA group used representational drawings. Analyses of the data indicated that students in both treatment groups improved overall in their understanding of fraction equivalency from pretest to posttest. On all achievement measures, students in the CRA group had overall higher mean scores than did students in the RA group. Implications for classroom instruction and suggestions for further research are discussed.  相似文献

Based on Common Core Standards (2010), mathematics interventions should emphasize conceptual understanding of numbers and operations as well as fluency. For students at risk for failure, the concrete‐representational‐abstract (CRA) sequence and the Strategic Instruction Model (SIM) have been shown effective in teaching computation with an emphasis on conceptual understanding. No studies have investigated the effects of CRA and SIM for teaching multiplication with regrouping. Therefore, the purpose of this study was to replicate and extend the literature, teaching subtraction and multiplication with regrouping using CRA and SIM. Three students receiving tier three mathematics interventions participated. A multiple‐probe across behaviors design was used to show a functional relation. All of the students demonstrated increases in fluency across all regrouping tasks.  相似文献

Studies have shown that there is a need for pedagogical content knowledge among science teachers. This study investigates two primary teachers and their objectives in choosing inquiry- and context-based instructional strategies as well as the relation between the choice of instructional strategies and the teachers’ knowledge about of students’ understanding and intended learning outcomes. Content representations created by the teachers and students’ experiences of the enacted teaching served as foundations for the teachers’ reflections during interviews. Data from the interviews were analyzed in terms of the intended, enacted, and experienced purposes of the teaching and, finally, as the relation between intended, enacted, and experienced purposes. Students’ experiences of the teaching were captured through a questionnaire, which was analyzed inductively, using content analysis. The results show that the teachers’ intended teaching objectives were that students would learn about water. During the enacted teaching, it seemed as if the inquiry process was in focus and this was also how many of the students experienced the objectives of the activities. There was a gap between the intended and experienced objectives. Hardly any relation was found between the teachers’ choice of instructional strategies and their knowledge about students’ understanding, with the exception that the teacher who also added drama wanted to support her students’ understanding of the states of water.  相似文献

Abstract

The study reported here examined college students’ academic self-efficacy, ‘academic press’ and learning achievement, as well as the association between these three variables within learning contexts using interactive whiteboard-based instruction. A quasi-experimental study was conducted using a sample (n = 103) of first-year college students in China. Participants were taught English by either an interactive whiteboard-based or traditional lecture-based instructional approach for three months. The results showed that the interactive whiteboard-based instructional intervention cultivated higher levels of academic press and academic self-efficacy among students and a significant, positive correlation was identified between these two variables. Students’ learning achievement was not affected by the instructional intervention. These results indicate that interactive whiteboard-based instruction offers some distinct benefits. In future work, additional research is needed to clarify how the instructional model relates to understanding learning achievement.  相似文献

This study explored the effects of literacy-rich sociodramatic guided play on kindergarten student literacy performance and behavior. Kindergarten students of varying socioeconomic status attending two elementary schools in the same school district participated in this repeated measures, counterbalanced design study. Students received the mandated grade-level literacy instruction with a supplemental 15 min block of time designated for play-based literacy integration during which the intervention took place. During this short time, students working in small groups were given materials (miniature items, toys, letter tiles) to practice initial letter sounds and consonant–vowel–consonant rhyming word families using either an assigned activity (control condition) or a student-invented game that practiced the same literacy concepts (experimental activity). Students instructed through the experimental condition scored significantly better on the Dynamic Indicators of Basic Early Literacy Skills (DIBELS) assessment with a medium effect size. Additional positive academic results included practice in story-composing, sequencing ideas into a complex cause and effect chain of events; application of new vocabulary; repeated practice of phonics and phonemic awareness skills to new examples; self-regulation of emotions; communication and negotiation with peers; and imagination, fantasy, humor, and creativity. Students evidenced preference for the experimental condition, continuing to repeat their games during recess or free time and to record them in their journals. Examples of student-generated literacy games are provided.  相似文献

Students with learning disabilities (LD) consistently struggle with word problem solving in mathematics classes. This difficulty has made curricular, state, and national tests particularly stressful, as word problem solving has become a predominant feature of such student performance assessments. Research suggests that students with LD perform poorly on word problem‐solving items due primarily to deficits in problem representation. Therefore, it is imperative that teachers provide these students with supplemental problem‐solving instruction that specifically targets the development of representational strategies. This article describes how one representational strategy, using number lines, can be used to model word problems as part of a comprehensive problem‐solving intervention to improve the conceptual understanding of math word problems and, subsequently, the problem‐solving performance of students with LD.  相似文献

This article explains how one teacher used iBooks Author, a free digital textbook creation tool that makes iBooks for iPads, in an upper elementary classroom to improve students’ expository writing skills and understanding of science content. The classroom teacher taught students pre-requisite writing and technology skills for two weeks, and then helped these students design, develop, and publish their own iBook. Students planned and developed content using Thinking Maps, storyboards, Google Docs, iMovie and other technology tools to create their iBook. A comparison of students’ work in the iBook to previous written work revealed an improvement in expository writing in multiple ways: better organization and connection of ideas; increased use of academic vocabulary; and an increased use of clarifying details and analogies. Students also gained a deeper understanding of science concepts as reported through their comments after the project was finished. Students became more proficient users of the technology, and also reported an increased sense of self-efficacy and confidence because they published a book in the iBookstore  相似文献

Abstract

?Multitiered systems of reading instruction and intervention, including response to intervention, are widely used in early reading by schools to provide more intense services to students who need them. Research using randomized controlled trials has compared innovative Tier 2 interventions to business-as-usual Tier 2 approaches and established a number of important components that compose effective Tier 2 interventions in early reading. The purpose of this study was to test the impact of a Tier 2 intervention with Tier 2 compared to Tier 1 instruction alone using regression discontinuity. A cut score was used to assign first-grade students at risk for reading difficulties to Tier 2 intervention plus Tier 1 instruction. Students who missed the cut score in the control group received Tier 1 instruction only. Students in the treatment group, just below the cut score, made greater gains on the SAT10 total score and the individual subtests than students just above the cut score. Outcomes were not significant on oral reading fluency.  相似文献

Computer-based multimedia presentations employing animated agents (avatars) can positively impact perceptions about engineering; the current research advances our understanding of this effect to pre-college populations, the main target for engineering outreach. The study examines the effectiveness of a brief computer-based intervention with animated agents in improving perceptions about engineering. Five hundred sixty-five elementary, middle-, and high-school students in the southwestern USA viewed a short computer-based multimedia overview of four engineering disciplines (electrical, chemical, biomedical, and environmental) with embedded animated agents. Students completed identical surveys measuring five subscales of engineering perceptions immediately before and after the intervention. Analyses of pre- and post-surveys demonstrated that the computer presentation significantly improved perceptions for each student group, and that effects were stronger for elementary school students, compared to middle- and high-school students.  相似文献

We examined the effectiveness of the Self-Regulated Strategy Development (SRSD) model of writing instruction with a self-determination training component for middle school-age students with emotional and behavioral disorders. We randomly assigned students to experimental or comparison treatments during which special education teachers provided the intervention. Students in the experimental groups received instruction on how to plan and write persuasive essays, were trained on self-determination skills, and were taught how to use persuasive writing to self-advocate. Students in the comparison condition received writing instruction with the established school writing curriculum. Instruction for both groups lasted 33 days, four days a week during 30-minute sessions. Experimental students significantly outperformed comparison students at posttest in all the persuasive essay-writing components assessed, in their ability to recall the parts of a persuasive essay, in the self-efficacy measure, and on self-determination knowledge. Experimental students were able to maintain gains in almost all writing measures and were able to generalize to content areas, although comparison students slightly increased in number of words. Student and teacher interviews revealed an overall satisfaction with SRSD procedures and the results.  相似文献

Students with specific poor comprehension (SPC) can sound out words accurately, but have difficulty understanding what they read. However, most existing reading intervention studies on students with reading disabilities did not differentiate students with SPC from other types of students with reading disabilities who accompany with decoding difficulties. The purpose of this systematic review was to synthesize findings from 14 experimental intervention studies that have included students with SPC with the goal of increasing reading comprehension. Out of eight types of interventions identified, Reciprocal Teaching (g = .856) demonstrated the largest effect size. Metalinguistic intervention showed the effect size of above .50 (a medium effect size), suggesting that intervention that explicitly teaches high-level oral language strategies was positive to improve reading performances of students with SPC. Findings also suggest a need to specify the classification criteria of students with SPC to broaden an understanding about the evidence-based intervention for students with SPC. Practical implications for effective practice, limitations, and future directions are discussed.  相似文献

This study examined differences in students’ classroom motivational climate perceptions and motivational beliefs between those enrolled in undergraduate Biology courses that implemented an innovative, active learning intervention and those enrolled in traditional Biology courses (control group). This study also sought to determine whether students’ classroom motivational climate perceptions and motivational beliefs mediated the effect of the intervention on course grades. Participants were 962 college students attending a large US public university. Students self-selected into one of the biology courses were randomly assigned to the intervention or control group. Multiple regression analyses indicated that students receiving the intervention reported greater instructor support, a perception of higher expectations for understanding (academic press), and a greater feeling that the course was interesting (situational interest). They also held higher self-efficacy and value for their biology course at completion compared to their counterparts in traditional biology classrooms. Moreover, mediation analyses indicated that the effect of the intervention on course grades was better explained through students’ classroom motivational climate perceptions and motivational beliefs. Results gained from this intervention may be useful to other campuses interested in enhancing student motivation and success even when faced with large enrolments and minimal faculty and staff support.  相似文献

Place is a concept used to explore how people ascribe meaning to their physical and social surrounds, and their emotional affects. Exploring the university as a place can highlight social relations affecting Australian Indigenous students’ sense of belonging and identity. We asked what university factors contribute to the development of a positive sense of place for these students. Findings are presented from two Australian universities, based on focus groups with Indigenous students, and interviews with Indigenous and non-Indigenous staff. Students prioritized relationships with academics as a key theme, stressing academic’s flexibility and understanding enabled their persistence at university. Students situationally manage self-identification, requiring academics to engage effectively with diverse students, but staff felt they required further professional development. We argue that academics can ‘make’ university places in their pedagogies and mentoring roles, but require universities to recognize this pedagogical caring as a legitimate and valued element of their work.  相似文献
