Architectural building safety and health performance model for stratified low-cost housing: education and management tool for building managers

The safety and health performances aspects of a building are the most challenging aspect of facility management. It requires a deep understanding by the building managers on the factors that contribute to health and safety performances. This study attempted to develop an explanatory architectural safety performance model for stratified low-cost housing in Malaysia. The proposed Building Safety and Health Performance (BSHP) model was tested empirically through a survey on 308 construction practitioners using partial least squares (PLS) and structural equation modelling (SEM) tool. Statistical analysis results supports the conclusion that architecture, building services, external environment, management approaches and maintenance management have positive influence on safety and health performance of stratified low-cost housing in Malaysia. The findings provide valuable insights for construction industry to introduce BSHP model in the future where the model could be used as a guideline for training purposes of managers and better planning and implementation of building management

Defining Technology for Learning: Cognitive and Physical Tools of Inquiry

This essay explores definitions of technology and educational technology. The authors argue the following points: 1. Educational stakeholders, and the public at large, use the term technology as though it has a universally agreed upon definition. It does not, and how technology is defined matters. 2. For technology in schools to support student learning, it must to be defined in a way that describes technology as a tool for problem-solving. 3. Integration of technology, particularly when paired with teacher-centered practices, has the potential of reinforcing and heightening the negative consequences of a conception of learning that positions students as recipients of knowledge instead constructors of knowledge. Essay concludes with a call for leaders in the field of educational technology to provide guidance by adopting a definition that encapsulates the third point above

Computer-assisted Mathematical Interventions on Word Problems for Elementary Students with Underachievement in Mathematics

Students with mathematical difficulties are more likely to consider word problems to be challenging due to their reading abilities, and they tend to use inferior strategies when in problem-solving situations compared to their peers. As one of the effective strategies, computer-based intervention has been used for improving the academic performance of students who are struggling with mathematics problem-solving. Computer-assisted instruction provides immediate corrective feedback, enables systematically sequenced curriculum based on individual’s academic performance, and helps students to improve their mathematical performance. This paper is to review the literature that examines computer-assisted interventions for mathematical word problems for elementary students with MD. In this paper, the findings of previous studies on math interventions focusing on word problems are summarized. Also, recent literature which examined the effectiveness of computer-assisted mathematical interventions for solving word problems for elementary students with MD is reviewed. Lastly, research findings, future recommendations, and implications are discussed

The Effects Of A Modified Learning Strategy On The Multiple Step Mathematical Word Problem Solving Ability Of Middle School Students With High-functioning Autism Or Asperger\u27s Syndrome

Students with HFA/AS present with a unique set of cognitive deficits that may prevent achievement in the mathematics curriculum, even though they present with average mathematical skills. The purpose of the study was to determine the effectiveness and efficiency of the use of a modified learning strategy to increase the mathematical word problem solving ability of children with high functioning autism or Asperger\u27s syndrome; determine if the use of Solve It! increases the self-perceptions of mathematical ability, attitudes towards mathematics and attitudes towards solving mathematical word problems; and, determine if Solve It! cue cards or a Solve It! multimedia academic story works best as a prime to increase the percentage correct if the student does not maintain use of the strategy. The subjects were recruited from a central Florida school district. Diagnosis of ASD was confirmed by a review of records and the completion of the Autism Diagnostic Inventory-Revised (Lord, Rutter, & Le Couteur, 2005). Woodcock Johnson Tests of Achievement (Woodcock, McGrew, & Mather, 2001) subtest scores for reading comprehension and mathematical computation were completed to identify the current level of functioning. The Mathematical Problem Solving Assessment- Short Form (Montague, 1996) was administered to determine the need for word problem solving intervention. The subjects were then taught a mathematical word problem solving strategy called Solve It!, during non-content course time at their schools. Generalization data were collected in each subject\u27s regular education mathematics classroom. Sessions were video-taped, work samples were scored, and then graphed using a multiple baseline format. Three weeks after the completion of the study, maintenance data were collected. If subjects did not maintain a high use of the strategy, they were entered into the second study to determine if a video prime or written prime served best to increase word problem solving. The results of the study indicate a functional relationship between the use of the Solve It! strategy and the percentage correct on curriculum based mathematical word problems. The subjects obtained efficient use of strategy use in five training sessions and applied the strategy successfully for five acquisition sessions. Percentage correct on mathematical word problems ranged from 20% during baseline to 100% during training and acquisition trials. Error analysis indicated reading comprehension interference and probable executive functioning interference. Students who did not maintain strategy use quickly returned to intervention level using a prime. Both primes, cue cards and multimedia academic story, increased performance back to intervention levels for two students. However, one prime, the multimedia academic story and not the cue cards, increased performance back to intervention levels for one student. Findings of this study show the utility of a modified learning strategy to increase mathematical word problem solving for students with high functioning autism and Asperger\u27s syndrome. Results suggest that priming is a viable intervention if students with autism do not maintain or generalize strategy use as a means of procedural facilitation

Basic calculation proficiency and mathematics achievement in elementary school children

The relation between skill in simple addition and subtraction and more general math achievement in elementary school is well established but not understood. Both the intrinsic importance of skill in simple calculation for math and the influence of conceptual knowledge and cognitive factors (working memory, processing speed, oral language) on simple calculation and math are plausible. The authors investigated the development of basic calculation fluency and its relations to math achievement and other factors by tracking a group of 259 United Kingdom English children from second to third grade. In both grades the group did not retrieve the solutions to most problems, but their math achievement was typical. Improvement in basic calculation proficiency was partially predicted by conceptual knowledge and cognitive factors. These factors only partially mediated the relation between basic calculation and math achievement. The relation between reading and math was wholly mediated by number measures and cognitive factors

Exploring the episodic structure of algebra story problem solving

This paper analyzes the quantitative and situational structure of algebra story problems, uses these materials to propose an interpretive framework for written problem-solving protocols, and then presents an exploratory study of the episodic structure of algebra story problem solving in a sizable group of mathematically competent subjects. Analyses of written protocols compare the strategic, tactical, and conceptual content of solution attampts, looking within these attempts at the interplay between problem comprehension and solution. Comprehension and solution of algebra story problems are complimentary activities, giving rise to a succession of problem solving episodes. While direct algebraic problem solving is sometimes effective, results suggest that the algebraic formalism may be of little help in comprehending the quantitative constraints posed in a problem text. Instead, competent problem solvers often reason within the situational context presented by a story problem, using various forms of "model-based reasoning" to identify, pursue, and verify quantitative constraints required for solution. The paper concludes by discussing the implications of these findings for acquiring mathematical concepts (e.g., related linear functions) and for supporting their acquisition through instruction

How Readability Factors Are Differentially Associated With Performance for Students of Different Backgrounds When Solving Mathematics Word Problems

The link between reading and mathematics achievement is well known, and an important question is whether readability factors in mathematics problems are differentially impacting student groups. Using 20 years of data from the National Assessment of Educational Progress and the Trends in International Mathematics and Science Study, we examine how readability factors – such as length, word difficulty, and pronouns – interact with student background characteristics – such as race/ethnicity, mathematics achievement, and socioeconomic status. Textual features that make problems more difficult to process appear to differentially negatively impact struggling students, while features that make language easier to process appear to differentially positively impact struggling students. It is critical that readability along various dimensions be considered when designing instruction and assessment

ImpacT2 project: preliminary study 1: establishing the relationship between networked technology and attainment

This report explored teaching practices, beliefs and teaching styles and their influences on ICT use and implementation by pupils. Additional factors explored included the value of school and LEA policies and teacher competence in the use of ICT in classroom settings. ImpaCT2 was a major longitudinal study (1999-2002) involving 60 schools in England, its aims were to: identify the impact of networked technologies on the school and out-of-school environment; determine whether or not this impact affected the educational attainment of pupils aged 816 years (at Key Stages 2, 3, and 4); and provide information that would assist in the formation of national, local and school policies on the deployment of IC
