Science Instruction for Students with Learning Disabilities: A Meta‐Analysis

Although science has received much attention as a political and educational initiative, students with learning disabilities (LD) perform significantly lower than their nondisabled peers. This meta‐analysis evaluates the effectiveness of instructional strategies in science for students with LD. Twelve studies were examined, summarized, and grouped according to the type of strategy implemented. Effect sizes (ES) were calculated for each study. Across all studies, a mean ES of .78 was obtained, indicating a moderate positive effect on students with LD science achievement. Findings also align with past reviews of inquiry‐based instruction for students with special needs, indicating that students with LD need structure within an inquiry science approach in order to be successful. Additionally, results suggest that mnemonic instruction is highly effective at increasing learning disabled students' acquisition and retention of science facts.     

Evaluation of the Effects of the Medium of Instruction on Science Learning of Hong Kong Secondary Students: Students’ Self-Concept in Science

A longitudinal study has been conducted to explore the impact of a new language policy for Hong Kong secondary schools on science learning. According to this policy, only schools that recruit the best 25% of students can teach science in English, the students' second language, while the other schools have to teach science in Chinese, the students' native language. The study involved a student cohort of 100 schools starting from S1 for three years. The outcome of science learning is conceptualized as consisting of students' achievement and self-concept in science. This paper reports the possible effects of English-medium instruction (EMI) and Chinese-medium instruction (CMI) on students' self-concept in science, as measured by students' responses to a questionnaire. Comparing with the CMI students, the EMI students showed higher self-concepts in Chinese, English and Mathematics, but a lower self-concept in science. This finding suggests that the EMI students might experience greater learning problems in science than in other subjects, probably because science learning involves abstract thinking and the mastery of scientific terminology which make a high demand on language proficiency. The EMI students showed a greater interest in learning science than the CMI students, indicating that they were more academically oriented. The EMI students, however, formed a lower perceived self-competence in science than their CMI peers, despite that they performed better in the science achievement test than many of the CMI students. This perception supports the view that using English for instruction may have negative effects on science learning. It is also consistent with the observation that the EMI students perceived science as more difficult to understand and learn than the CMI students.     

Computer Technology,Science Education,and Students with Learning Disabilities

The ways computer technology could be used to teach science to students with learning disabilities (LD) are explored. Science is for all students and that includes students with LD. Learning science has both cognitive and affective implications for students with LD. In this context, computer technology provides cognitively engaging and motivating instructional tools for individualizing the mode of delivery; developing expert tutors; anchoring instruction; integrating science with other subjects; reducing cognitive load on working memory; and motivating students to stay on task. These applications are discussed with implications for teaching science to students with LD.     

Revealing the hidden world of research

Bringing the science of schooling into standard practice for students with learning disabilities (LD) is a threefold process that requires understanding the nature and features of high-quality instruction, encouraging their use, and developing and maintaining systems that can sustain them. Examples are drawn from the LD research base to illustrate each of these areas, with a focus on research in reading acquisition with young children at risk of LD and with older students with LD. These examples suggest a continued push for special education reading instruction through and past the elementary years. I conclude with recommendations for preparing teachers that take advantage of the knowledge gained from research-to-practice endeavors across the country.     

Effects of Computer-Assisted Instruction on the Mathematics Performance of Students with Learning Disabilities: A Synthesis of the Research

ABSTRACT

Over the past decades, there has been a significant increase in the use of computers and mobile devices in schools as part of mathematics instruction for students with learning disabilities (LD). The purpose of this synthesis was to provide a systematic review of the research on the effects of computer-assisted instruction (CAI) for both computers and mobile devices when teaching mathematics to students with LD. Twenty studies met the selection criteria that were published between 1980 and 2017. Findings revealed a wide range of effect sizes across the studies, but in general, the results represent a medium intervention effect and a large maintenance effect of using CAI for students with LD on their mathematics progress. In addition, findings revealed a relationship between the number of evidence-based instructional variables embedded in the CAI instruction and the effect on student performance. Overall, results indicated that well designed CAI with effective instructional variables should be considered as a promising intervention to support mathematics instruction for students with LD.     

Science Education and Students with Learning Disabilities

Students with learning disabilities (LD) are increasingly expected to master content in the general education curriculum, making the need for effective instructional supports more important than ever before. Science is a part of the curriculum that can be particularly challenging to students with LD because of the diverse demands it places on cognitive performance. In this summary we review a number of strategies that have been validated for learners with LD. The strategies include supports for (a) verbal learning of declarative information, (b) processing information in texts, (c) activities‐based instruction/experiential learning, (d) scientific thinking and reasoning, and (e) differentiated instruction. We also summarize the research regarding the impact of teacher behavior on achievement for students with LD in science education. The strategies reviewed yield tangible and positive effect sizes that suggest that their application to the target domain will substantially improve outcomes for students with LD in science education.     

Reading Science Text: Challenges for Students with Learning Disabilities and Considerations for Teachers

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.     

A Randomized Study of a Literacy-Integrated Science Intervention for Low-Socio-economic Status Middle School Students: Findings from first-year implementation

This paper presents the findings from a randomized control trial study of reading/literacy-integrated science inquiry intervention after 1 year of implementation and the treatment effect on 5th-grade low-socio-economic African-American and Hispanic students’ achievement in science and English reading. A total of 94 treatment students and 194 comparison students from four randomized intermediate schools participated in the current project. The intervention consisted of ongoing professional development and specific instructional science lessons with inquiry-based learning, direct and explicit vocabulary instruction, and integration of reading and writing. Results suggested that (a) there was a significantly positive treatment effect as reflected in students' higher performance in district-wide curriculum-based tests of science and reading and standardized tests of science, reading, and English reading fluency; (b) males and females did not differ significantly from participating in science inquiry instruction; (c) African-American students had lower chance of sufficiently mastering the science concepts and achieving above the state standards when compared with Hispanic students across gender and condition, and (d) below-poverty African-American females are the most vulnerable group in science learning. Our study confirmed that even a modest amount of literacy integration in inquiry-based science instruction can promote students' science and reading achievement. Therefore, we call for more experimental research that focus on the quality of literacy-integrated science instruction from which middle grade students, particularly low-socio-economic status students, can benefit.     

Special Education Teacher Education: A Perspective on Content Knowledge

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.     

Elementary Science Education in Classrooms and Outdoors: Stakeholder views,gender, ethnicity,and testing

In this article, we present a mixed-methods study of 2 schools’ elementary science programs including outdoor instruction specific to each school's culture. We explore fifth-grade students in measures of science knowledge, environmental attitudes, and outdoor comfort levels including gender and ethnic differences. We further examine students’ science and outdoor views and activity choices along with those of adults (teachers, parents, and principals). Significant differences were found between pre- and posttest measures along with gender and ethnic differences with respect to students’ science knowledge and environmental attitudes. Interview data exposed limitations of outdoor learning at both schools including standardized test pressures, teachers’ views of science instruction, and desultory connections of alternative learning settings to ‘school' science.     

Race And Ethnicity: Powerful Cultural Forecasters Of Science Learning And Performance

This article addresses the impact of race and ethnicity on students' science learning in US schools. Specifically, it discusses (a) the constructs of race, ethnicity, and culture, and the racial and ethnic student composition in US public schools; (b) effective classroom practices for curriculum, instruction, and assessment related to race and ethnicity; and (c) future policy and practice regarding race and ethnicity in science education. We discuss the science learning and teaching of African American, Latino, and Asian American students. Even though Asian American students are viewed as the model minority, some struggle with science learning, because their languages and cultures are seen as hurdles. As there is little defendable science education research related to Native Americans at the precollege level, we remain silent in this area.     

Math,Science, and Foreign Language: Evidence‐Based Accommodation Decision Making at the Postsecondary Level

Accommodations in postsecondary settings have become commonplace for many students with learning disabilities (LD) who have documented needs. Many of the accommodations professionals recommend for students with LD are based on an analysis of the course demands, the student's functional limitations, and a basic understanding of how the accommodation can facilitate the demonstration or acquisition of knowledge. However, little is known about which accommodations are recommended for math, science, and foreign language courses as well as the effectiveness of those accommodations. Because these content areas pose substantial hurdles for secondary students with LD who may transition to postsecondary settings, a review of the literature was conducted to evaluate current practices in the provision of accommodations to postsecondary students with LD in math, science, and foreign language courses. Findings indicate strong empirical evidence for extended test time for algebra exams and emerging research in changes to foreign language instruction. Recommendations for further research are provided.     

Transforming administration to support science in the schoolhouse for students with disabilities

I examine the role that administrators play in facilitating the development, adoption, use, and evaluation of scientifically based interventions within the school culture to support the educational outcomes of students with learning disabilities (LD). Two ways of transforming the administrative role to support science in the schoolhouse are presented; one considers the importance of including language in future legislation that acknowledges the role of administrators in school reform, and the other focuses on establishing a national research agenda addressing issues of leadership and special education. I argue that these 2 venues should serve to identify and to stimulate the use of evidence-based administrative practices that ultimately increase educational outcomes for students with LD, improve teacher instruction, and transform the leadership mission.     

“An adjective is a word hanging down from a noun”: Learning to write and students with learning disabilities

By the upper elementary grades, writing becomes an essential tool both for learning and for showing what you know. Students who struggle significantly with writing are at a terrible disadvantage. Data from the National Assessment of Educational Progress indicate that only 25% of students can be classified as competent writers; students with learning disabilities (LD) have even greater problems with writing than their normally achieving peers and frequently demonstrate a deteriorating attitude toward writing after the primary grades. In this article, we focus on composing and the writing process, and examine the knowledge base about writing development and instruction among students with LD. We address what research tells us about skilled writers and the development of writing knowledge, strategies, skill, and the will to write, and how this relates to students with LD. Next, we summarize what has been learned from research on writing development, effective instruction, and the writing abilities of students with LD in terms of effective instruction for these students. Finally, we indicate critical areas for future research.     

Integrating Science And English Proficiency For English Language Learners

Despite the expectation that all students should achieve high academic standards, content area instruction and English for speakers of other languages instruction for English language learners (ELLs) have traditionally been conceptualized as separate domains, resulting in educational inequities for ELLs. This is because effective instruction to promote academic achievement for ELLs requires integration of content and language. Such inequities are more pronounced in urban schools where ELLs are disproportionately represented. In science education, research on instructional interventions to simultaneously promote science and English proficiency of ELLs has begun to emerge in recent years. Grounded in this emerging research literature, we offer specific instructional strategies to integrate science and English proficiency for ELLs in five domains: (a) literacy strategies with all students, (b) language support strategies with ELLs, (c) discourse strategies with ELLs, (d) home language support, and (e) home culture connections.     

Teaching Students with Learning Disabilities to Cope in Middle School

The purpose of this article is to explore how to teach students with learning disabilities (LD) to cope effectively, so that they may develop self-determination (independence) skills in middle school. Teachers need to understand the definition of coping and what makes coping effective. They can then tailor instruction of students with LD with effective coping in mind. I describe the various ways in which the frame of instruction and specific methods can allow students with LD to cope effectively in school and hopefully, beyond it.     

Common Core State Standards,Writing, and Students with LD: Recommendations

This article examines the Common Core State Standards as they apply to writing and students with learning disabilities (LD). We first consider why the implementation of these standards is advantageous to writing instruction for students with LD as well as the challenges in implementing them. Next, we make the following four recommendations in terms of their implementation: (1) increase general and special education teachers’ knowledge about writing development; (2) create a writing environment in which students with LD can thrive; (3) employ evidence‐based writing practices in general education classes (where most students with LD are taught); and (4) use evidence‐based writing practices effective with students with LD. We conclude by considering research that still needs to be undertaken to help educators maximize the probability that students with and without LD meet the writing benchmarks proposed in these Standards.     

Science education as a pathway to teaching language literacy: a critical book review

In this paper, I present a critical review of the recent book, Science Education as a Pathway to Teaching Language Literacy, edited by Alberto J. Rodriguez. This volume is a timely collection of essays in which the authors bring to attention both the successes and challenges of integrating science instruction with literacy instruction (and vice versa). Although several themes in the book merit further attention, a central unifying issue throughout all of the chapters is the task of designing instruction which (1) gives students access to the dominant Discourses in science and literacy, (2) builds on students’ lived experiences, and (3) connects new material to socially and culturally relevant contexts in both science and literacy instruction—all within the high stakes testing realities of teachers and students in public schools. In this review, I illustrate how the authors of these essays effectively address this formidable challenge through research that ‘ascends to the concrete’. I also discuss where we could build on the work of the authors to integrate literacy and science instruction with the purpose of ‘humanizing and democratizing’ science education in K-12 classrooms.     

Technology Integration in a Science Classroom: Preservice Teachers’ Perceptions

The challenge of preparing students for the information age has prompted administrators to increase technology in the public schools. Yet despite the increased availability of technology in schools, few teachers are integrating technology for instructional purposes. Preservice teachers must be equipped with adequate content knowledge of technology to create an advantageous learning experience in science classrooms. To understand preservice teachers’ conceptions of technology integration, this research study explored 15 elementary science methods students’ definitions of technology and their attitudes toward incorporating technology into their teaching. The phenomenological study took place in a science methods course that was based on a constructivist approach to teaching and learning science through science activities and class discussions, with an emphasis on a teacher beliefs framework. Data were collected throughout the semester, including an open-ended pre/post-technology integration survey, lesson plans, and reflections on activities conducted throughout the course. Through a qualitative analysis, we identified improvements in students’ technology definitions, increased technology incorporation into science lesson plans, and favorable attitudes toward technology integration in science teaching after instruction. This research project demonstrates that positive changes in beliefs and behaviors relating to technology integration in science instruction among preservice teachers are possible through explicit instruction.     

The Self–Concept of Students with Learning Disabilities: A Meta–Analysis of Comparisons Across Different Placements

Although placement in less restrictive settings is generally believed to be associated with more positive social outcomes for students with disabilities, the empirical research has yielded equivocal findings. The purpose of this study was to synthesize the empirical research comparing the self–concept of students with learning disabilities (LD) in different educational placements. Meta–analysis revealed no overall association between self–concept and educational placement for four out of five comparisons: regular class vs. resource room, regular class vs. self–contained class, resource room vs. self–contained class, and regular class vs. special school. Students with LD receiving instruction in self–contained classrooms in regular schools exhibited lower self–concept compared to students with LD attending special schools. Follow–up analyses were conducted to explore whether the variability of effect sizes in regular class–resource room comparisons was associated with any of several potential moderator variables; the only variable for which the association approached significance was whether students in the regular classroom were provided with appropriate special education supports and services. The findings are discussed in light of documented individual variation in students’ placement preferences.
