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.     

Using Explicit and Strategic Instruction to Teach Division Skills to Students With Learning Disabilities

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.

Training Teachers to Use Food to Teach Science

ABSTRACT:  In January 2006, every science department chair in U.S. public, private, and parochial high schools received information on food science, including a DVD, poster, and experiment guide developed by the Institute of Food Technologists (IFT), IFT Foundation, and Discovery Education. To promote the experiments and to encourage implementation of the program's components in secondary schools, the IFT K-12 Career Guidance Committee presented a teacher training session at the national IFT Annual Meeting + Food EXPO® in Orlando, Florida, on Monday, June 26, 2006. Twenty Orlando-area science teachers were treated to 3 h of activities, during which they performed and learned how to teach 3 experiments from the areas of physics, chemistry, and biology, demonstrated by the committee. In addition, to extend the effects of the session beyond the Orlando area, IFT member Food Science Ambassadors were invited to the training session so that they could become proficient in demonstrating the experiments, and to equip them with the knowledge to host a training session in their own geographical area in the future. Fifteen Food Science Ambassadors attended the session. After lab time, K-12 Career Guidance Committee members and IFT Student Association (IFTSA) chapter presidents led small groups of teachers on tours of the EXPO floor to learn more about how science is applied in the food industry.

Learning What It Takes to Teach Science: High School Students as Science Teachers for Middle School Students

This study examines the influence of St. John's University Summer Science Experience and Teacher Mentoring Program on African American and Hispanic high school students' interest in science and science teaching as career goals. In the first phase of the program, high school students from six school districts in Suffolk County, Long Island (a suburb of metropolitan New York City) engaged in investigative science experiences that emphasized environmental science, chemistry, and technology and learned about effective science pedagogy. The second phase of the program functioned as a teaching practicum for the high school students, where they planned for instruction and taught middle school students investigations similar to those that they had engaged in during the summer program. Various surveys were developed to assess high school students' attitudes about science and science teaching, knowledge of effective teaching approaches, knowledge of ways to motivate younger students, and the overall impact of the program on the high students' interest in science and/or science teaching as career goals. Program evaluations reveal that over 75% of the students expressed an interest in considering science or science teaching as career possibilities. Implications for minority teacher recruitment are discussed.     

Marijuana Use in Suburban Schools Among Students With Learning Disabilities

Although much research exists on adolescent marijuana use, few studies have examined marijuana use in school settings. Students experiencing academic and social difficulties at school, such as those receiving special education services, may be more at risk for school-related substance use. Nevertheless, virtually no research has examined this problem. This study assessed the prevalence of marijuana use at school and the perceived availability and consequences of using marijuana in school among students with learning disabilities. The results showed that 15 percent of students reported using marijuana at school, and that marijuana was easily obtained. Most students perceived marijuana to be harmful to their schoolwork, and many non-users felt unsafe and angry when drugs were present at school.     

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.     

Social Attributions of Students With Learning Disabilities

The purpose of this study was to examine the social attributions of students with learning disabilities (LD) compared to those of nonlearning-disabled (NLD) low- achieving (LA) and average-achieving (AA) students. Ninety-two subjects partici- pated in the study; 32 students with LD and two matched control groups that consisted of 29 LA and 33 AA students. The results indicated that students with LD were likely to exhibit different social attribution patterns than did their NLD peers. They displayed a greater tendency to use external factors in explaining their social successes and failures, while attributing their successes to internal factors, than did LA and AA students. LA and AA students, conversely, were more likely to use interactional explanations of social events.     

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.     

On Teaching Science Teachers to Teach

Abstract

Universities and colleges have a responsibility to help solve complex social problems. The article describes an interdisciplinary approach that integrates the diverse strengths of a research and teaching institution to address issues in one such complex problem: race, science, and health. The authors' model involved a “feedback loop” among three different and simultaneous activities: two undergraduate courses, one in biology and one open to all first-year student, and a weekly seminar that included the professors teaching these two courses, other faculty from across the university, and undergraduate and graduate student representatives. The topic and logistical strategies are discussed in detail and the value and challenges of such an integrated multilevel approach are explored.     

Augmented Reality for Teaching Science Vocabulary to Postsecondary Education Students With Intellectual Disabilities and Autism

The purpose of this study was to examine the use of an emerging technology called augmented reality to teach science vocabulary words to college students with intellectual disability and autism spectrum disorders. One student with autism and three students with an intellectual disability participated in a multiple probe across behaviors (i.e., acquisition of science vocabulary words) design. Data were collected on each student's ability to define and label three sets of science vocabulary words (i.e., bones, organs, and plant cells). The results indicate that all students acquired definition and labeling knowledge for the new science vocabulary terms. Results are discussed in the context of applying universal design principles with emerging technologies to create authentic opportunities for students with intellectual disabilities and autism spectrum disorders to learn science vocabulary.

Exploring How Creating Stop-Motion Animations Supports Student Teachers in Learning to Teach Science

This article reports on an exploration of teaching and learning through creating rudimentary stop-motion animations set up to identify how learning opportunities involving stop-motion animations can support student learning and science teacher education. Participants were student teachers, volunteers representing both secondary and primary school teacher training courses, from three universities in England. Their discussions while making an animation themselves were recorded. Six of the secondary trainees were later interviewed after having taught using animation during placement in school. Thematic analysis of the content of the recordings and interviews showed that the student teachers view the opportunities that making an animation creates for peer discussion as the most likely to promote learning. Modeling was also seen as beneficial, though no one particular activity or stage in animation creation stood out as being more effective than another. It is the holistic process of representing and re-representing one's scientific knowledge in different modes that made animation creation appear to be so useful in bringing about and supporting learning. With respect to teacher education, the student science teachers reported that making animations themselves supported them in thinking through the process of how, as teachers, they would need to communicate the underpinning science to others.

The Science and Politics of Gifted Students With Learning Disabilities: A Social Inequality Perspective

Researchers and advocates who argue for increased recognition of gifted students with learning disabilities (G/LD students) often frame their arguments in terms of the need to increase the diversity and inclusiveness of gifted education. However, the criteria used to identify G/LD students are sufficiently vague and fluid that the G/LD category can serve as a vehicle for the very elitism and social class reproduction that the category's advocates abhor. Empirical research suggests that G/LD students often fail to satisfy traditional criteria for either aspect of their label, while the incentives of the classification are nonetheless evident to knowledgeable parents and school personnel. Implications of these findings for practice are discussed.     

Personal Narratives of Students With and Without Learning Disabilities

This study investigated personal narratives produced by children with and without learning disabilities in the context of naturalistic conversation. The high‐point analysis was applied to compare the referential and evaluative aspects of children's personal narratives. Participants were 60 students in Grades 4 and 5 in public suburban schools, with an almost equal number of boys and girls. The participants with learning disabilities were matched individually with typically achieving peers for chronological age, grade, ethnicity, and gender. Despite significant differences in expressive semantic and syntactic skills, both groups produced narratives that were equivalent in terms of length, structural organization, and global coherence. Group differences centered around the decreased inclusion of high points in narratives produced by girls with learning disabilities, indicating that these girls may struggle with generating coherent personal narratives and communicating their own perspective on the recounted personal experiences. This specific narrative performance is accounted for by the unique profile of cognitive and academic characteristics demonstrated by girls with learning disabilities. Practical implications for the multifaceted assessment of referential and evaluative narrative functions are discussed, and interventions for enhancing narrative skills are suggested. The study's findings are also discussed in the context of previous research and directions for future inquiries.     

Disabilities Among Norwegian Students Found Eligible for Special Education

The prevalence of different disabilities in a sample of 780 students found eligible for special education in Norway is presented in this article. Each student was judged in relation to 10 different disabilities, and the frequencies of the different disabilities were reported. Almost all students had more than one problem or disability. It is argued that statistics related to students with disabilities that ascribe each student only to one category of disability do not provide a correct picture of the prevalence of different disabilities. The most common disabilities reported in this study were psychosocial problems, intellectual disability, and communication disorders that were found in about 40 to 50% of the students. About one third of the students were reported to have attention deficit disorder or physical disabilities, 25% experienced social stress outside school, and 20% had medical problems. Hearing and visual impairments are reported for about 5% and 6% of the sample respectively.     

Using the Stepped Care Model to Empower University Students With Learning Disabilities

Students with learning disabilities face several challenges in postsecondary education settings. The authors explore the issue and shed light on the importance of self‐advocacy for academic success. The stepped care model (SCM) is suggested as an approach to assist college students with learning disabilities in developing these skills and obtaining services. A brief case example from 1 of the authors' work is shared to illustrate the use of the SCM with a student with a learning disability.
