Problem Solving in Geometry: Comparing the effects of non-goal specific instruction and conventional worked examples

This study examines the extended effects of an instructional program designed to enhance schema development by using non-goal specific problems, in the teaching of geometry to high school students in need of remedial tuition. A multiple baseline across-subjects experimental design was used to compare the effects of this program with another method of teaching this subject--that is, using worked examples. This methodology provides detailed information on the shifts and changes associated with learning processes for particular individuals during the actual process of schema acquisition. Dependent measures included test performance, error analysis, time analysis, directionality and generalisation. Results indicate that participants in the non-goal specific group showed greater improvements, solving problems faster, more efficiently, more accurately and with fewer errors and greater consistency. These findings are discussed in terms of their implications for the design of mathematics instructional material.     

Mathematics education in its cultural context

This paper presents the results of a series of analyses of educational situations involving cultural issues. Of particular significance are the ideas that all cultural groups generate mathematical ideas, and that Western mathematics may be only one mathematics among many. The values associated with Western mathematics are also discussed, and various issues raised by these analyses are then presented.     

Consenting Adults Only? Patient education in the doctor's surgery

This paper explores patient education in the general practice setting. It draws on a research study carried out in Nottinghamshire, UK, to challenge the view that doctors use their power in educational encounters to silence or dupe patients into accepting normative social patterns and relationships. The study found that power appeared to work in a different and more subtle way. Patients chose to subject themselves to the controlling effects of a dominant patient educational discourse (prevention) due to its wider cultural association with freedom, personal betterment and bodily health. The paper concludes by suggesting that challenges to reactionary political forces need to address how dominant discourses work at the level of desire to seduce people into conformity.     

The role of environment in the development of reading skills: a longitudinal study of preschool and school-age measures

The purpose of this study was to extend previous studies on the influence of environmental measures on intelligence scores by examining how proximal and distal measures of children's environments in the preschool period and in the primary-grade period are related to their performance on reading achievement tests. Reading performance was explored using two approaches. The first approach involved the identification of children within a longitudinal sample who had poor reading skills at 8 years of age. The second approach used the full range of reading scores to explore whether factors influencing poor reading were different from those influencing good reading. Participants were 113 children, including 35 children with poor reading skills, who were part of a longitudinal study of cognitive development. Socioeconomic status (SES), Home Observation for Measurement of the Environment (HOME) scores at 3 and 10 years of age, and school-administered and individually administered reading achievement scores were obtained. Both SES and HOME scores were found to be related to reading abilities, but preschool environment measures were more strongly and consistently related to and predictive of reading scores. Differences in the patterns of correlations and the results of the predictive models were found between the full sample and the poor readers. Variables other than proximal and distal measures of the environment are involved in the development of reading skills.     

The roots and routes of environmental and sustainability education policy research – an introduction to a virtual special issue

This article introduces the themes of a virtual special issue (VSI) of Environmental Education Research (http://explore.tandfonline.com/content/ed/ceer-vsi) focused on policy research in environmental and sustainability education (ESE). The broad purpose behind preparing the VSI was to consider the challenges involved in linking particular concepts of environment and sustainability with key themes in educational policy, and how this remains a heavily contested practice. Examples drawn from two decades of studies published in the journal show how these might be illustrated, addressed, problematized and possibly transcended. The introduction traces how ESE researchers have dealt with key trends, complexities and issues in the policy-practice-research nexus both conceptually and empirically. It also illustrates how researchers within the field might reimagine and reinvigorate policy research on ESE, and how working with researchers from other fields who offer different perspectives, ideas and expertise might aid the cross-fertilisation of a complex terrain of ideas, policy and practice. In so doing, we hope the accompanying VSI inspires renewed interest into the (at times, fickle) relationship between ESE, and the dual worlds of possibility and tension that take place both within, and surrounding, their fields of policy and research.     

Universal Design for Learning in Pre-K to Grade 12 Classrooms: A Systematic Review of Research

Some researchers have characterized Universal Design for Learning (UDL) as a promising framework to provide diverse students with access to the general education curriculum, but to what extent and how have UDL-based interventions fulfilled that promise? The purpose of this review was to analyze studies that investigated impacts of UDL-based instruction on academic and social outcomes for pre-K to grade 12 students. For the 13 studies that qualified for our review, we analyzed how researchers applied UDL principles as well as outcomes and efficacy of UDL-based interventions. Results of this analysis suggest that overall, UDL-based instruction has the potential to increase engagement and access to general education curriculum for students with disabilities, and improve students’ academic and social outcomes. However, we found mixed results; the efficacy of UDL-based interventions varied considerably within and across many studies, with effect sizes ranging from small to large. In addition, we found that although authors noted that their interventions were UDL-based, there was considerable variance in how authors reported connections between specific UDL guidelines and components of their interventions.     

Maltreatment's wake: the relationship of maltreatment dimensions to child outcomes

OBJECTIVE: The aim of this exploratory study was to examine the extent to which, in combination, the best constructions of basic dimensions of maltreatment, identified in other papers from LONGSCAN, predict child outcomes. METHOD: Maltreatment records of a sample of 203 children were used to define dimensions of maltreatment related to Type, Severity, Chronicity, and Age at First Report. The definitions were based upon findings presented in other papers in this special issue. Children's behavioral and emotional functioning was examined at age 8 using standardized measures of problem behaviors, socialization and adaptation, and trauma symptomatology. Backward elimination regression was used to screen for interactions among the dimensions; regression models including dimensions and significant interactions were then run for each child outcome. Stratified partial correlations were utilized to explicate significant interactions. RESULTS: Individual maltreatment dimensions were found to have distinct effects on child functioning. Additionally, dimensions of maltreatment were interrelated and interacted in determining outcomes. Type of maltreatment (as indicated by the maximum severity rating of each type) was the most consistent predictor across outcomes, albeit different types predicted different outcomes. Various dimensional interactions were significant predictors of different outcomes. CONCLUSION: The results suggest that a comprehensive assessment of a child's maltreatment experience, including type and severity, when the maltreatment began and the pattern of maltreatment across the life span, is important to understanding the effects of maltreatment on children's growth and development.     

From Implementation to Efficacy: Factors Affecting Kenyan Secondary Teachers’ Technology Integration

Teaching is a complex practice that requires teachers to draw upon their content knowledge, pedagogical approaches and strategies, and knowledge about learners in order to support learning. Integrating technology into the teaching and learning practice of a classroom is a strategy that many teachers are drawing upon. This article reports on the initial findings on information communication technology (ICT) implementation in Kenyan secondary schools and discusses factors affecting effective technology integration. The study used questionnaire and classroom observation data to examine what types of ICTs for education are available in secondary schools in Kenya and what training teachers have had in using ICTs for education; teachers’ perspectives regarding the role of ICT in teaching and learning; and what factors might influence ICT integration in teaching and learning in public secondary schools in Kenya. The study found that while few teachers are integrating ICT into their teaching and learning, many teachers are implementing ICT in their teaching.
