The use of IQ scores and discrepancy formulas for identifying specific learning disabilities (SLD) has been widely discredited by prominent researchers for more than a decade. Nevertheless, the overwhelming majority of state policies still specify the use of discrepancy formulas, including the simple difference method, which is psychometrically inferior to regression-based methods. This study compares the use of a minimum IQ cutoff score and a simple difference method versus a regression-based method for identifying SLD in a sample of African American and European American full-time college students (N = 117). Replicating the findings from previous studies using typically achieving children, typically achieving adults, and school-age children with SLD, this study adds to the chorus of voices criticizing the use of outdated assessment practices that can have deleterious effects for individuals with SLD. The implications for legislative policy are discussed in the context of the historical overrepresentation of African Americans in all special education categories except SLD and the increased access to higher education that students with SLD have gained during the past decade. 相似文献

This paper describes part of a project called Modeling Across the Curriculum which is a large-scale research study in 15 schools across the United States. The specific data presented and discussed here in this paper is based on BioLogica, a hypermodel, interactive environment for learning genetics, which was implemented in multiple classes in eight high schools. BioLogica activities, data logging, and assessments were refined across this series of implementations. All students took a genetics content knowledge pre- and posttests. Traces of students' actions and responses to computer-based tasks were electronically collected (via a log file function) and systematically analyzed. An intensive 3-day field test involving 24 middle school students served to refine methods and create narrative profiles of students' learning experiences, outcomes, and interactions with BioLogica. We report on one high school implementation and the field test as self-contained studies to document the changes and the outcomes at different phases of development. A discussion of design changes concludes this paper. 相似文献

Recent advances in artificial intelligence (AI) could be used to improve occupational instruction in complex subjects with
sophisticated performance goals, such as those required for high-technology jobs. Educational devices incorporating AI would
“understand”what, whom, andhow they were teaching and could therefore tailor content and method to the needs of an individual learner without being limited
to a repertoire of prespecified responses. Intelligent Computer Assisted Instruction (ICAI) encompasses a spectrum of approaches,
including Socratic tutoring systems, simulation environments with embedded coaches, and “empowering environments” which aid
workers in using intelligent tools in complementary cognitive partnerships. This article focuses on (a) depicting how present
training methods might change if intelligent instructional devices were incorporated, (b) delineating the current state of
the art in the areas of research needed to produce such systems, and (c) indicating in which types of adult educational settings
ICAI might be productive and cost effective. 相似文献

This study investigated the relationships between role models, approaches to studying, and self‐efficacy in students attending a high school specialising in educating those with emotional and behavioural difficulties (EBD, n = 30) and students attending a mainstream high school (n = 41) in the UK. Types and quantity of role models held by students were assessed using semi‐structured interviews. Approaches to studying and self‐efficacy were measured using the Approaches and Study Skills Inventory for Students and the General Self‐Efficacy Scale, respectively. In the EBD sample, the quantity of personally known role models correlated positively with deep and strategic approaches to studying, while quantity of media role models correlated negatively with a deep approach to studying and general self‐efficacy. In the mainstream sample, no association was found between quantity of role models, on the one hand, and approaches to studying and self‐efficacy, on the other hand. The findings suggest that EBD students would benefit from direct exposure to more interpersonal role models, which would further their chances of selecting and assimilating adaptive attitudes and behaviours. 相似文献

Over the past decade, the field of teacher professional learning has coalesced around core characteristics of high quality professional development experiences (e.g. Borko, Jacobs, & Koellner, 2010. Contemporary approaches to teacher professional development. In P. L. Peterson, E. Baker, & B. McGaw (Eds.), International encyclopedia of education (Vol. 7, pp. 548–556). Oxford: Elsevier.; Darling-Hammond, Hyler, & Gardner, 2017. Effective teacher professional development. Palo Alto, CA: Learning Policy Institute). Many countries have found these advances of great interest because of a desire to build teacher capacity in science education and across the full curriculum. This paper continues this progress by examining the role and impact of an online professional development community within the top-down, large-scale curriculum and assessment revision of Advanced Placement (AP) Biology, Chemistry, and Physics. This paper is part of a five-year, longitudinal, U.S. National Science Foundation–funded project to study the relative effectiveness of various types of professional development in enabling teachers to adapt to the revised AP course goals and exams. Of the many forms of professional development our research has examined, preliminary analyses indicated that participation in the College Board's online AP Teacher Community (APTC) – where teachers can discuss teaching strategies, share resources, and connect with each other – had positive, direct, and statistically significant association with teacher self-reported shifts in practice and with gains in student AP scores (Fishman et al., 2014). This study explored how usage of the online APTC might be useful to teachers and examined a more robust estimate of these effects. Findings from the experience of AP teachers may be valuable in supporting other large-scale curriculum changes, such as the U.S. Next Generation Science Standards or Common Core Standards, as well as parallel curricular shifts in other countries. 相似文献

Just as information technology has improved effectiveness in medicine, finance, manufacturing, and numerous other sectors of society, advanced computing and telecommunications have the potential to help students master complex 21st-century skills. Research-based curriculum projects are developing examples of technologies that enable online virtual communities of practice using advanced tools to solve realworld problems. Learners engage in guided, reflective inquiry through extended projects that inculcate sophisticated concepts and skills and generate complex products. Pupils act as partners in developing learning experiences and generating knowledge, and students' collaborative construction of meaning is enhanced via different perspectives on shared experiences. Simulation and visualization tools help students recognize patterns, reason qualitatively about physical processes, translate among frames of reference, and envision dynamic models. These curricular approaches improve success for all types of learners and may differentially enhance the performance of at-risk students. 相似文献

The purpose of this study was to document how teachers and students describe and comprehend the ways in which participating
in an augmented reality (AR) simulation aids or hinders teaching and learning. Like the multi-user virtual environment (MUVE)
interface that underlies Internet games, AR is a good medium for immersive collaborative simulation, but has different strengths
and limitations than MUVEs. Within a design-based research project, the researchers conducted multiple qualitative case studies
across two middle schools (6th and 7th grade) and one high school (10th grade) in the northeastern United States to document
the affordances and limitations of AR simulations from the student and teacher perspective. The researchers collected data
through formal and informal interviews, direct observations, web site posts, and site documents. Teachers and students reported
that the technology-mediated narrative and the interactive, situated, collaborative problem solving affordances of the AR
simulation were highly engaging, especially among students who had previously presented behavioral and academic challenges
for the teachers. However, while the AR simulation provided potentially transformative added value, it simultaneously presented
unique technological, managerial, and cognitive challenges to teaching and learning. 相似文献
