Teaching the design and interpretation of graphs through computer-aided graphical data analysis

Graphs are one of the primary means of exploration and communication in the practice of science, but students in science laboratories are customarily taught only the low-level mechanics of constructing a single kind of graph when given a table of information. The use of a microcomputer can relieve the drudgery of plotting, allowing students to pursue higher-level issues in the design and interpretation of graphs through repeated “thought experiments.” We introduced computer-assisted graphical data analysis to inner-city high school students with weak math and science backgrounds, emphasizing the dynamic manipulation of various kinds of graphs to answer specific questions. Drawing on extensive recordings and classroom observations, we describe examples of the performance of these students on open-ended problem-solving tasks in which graphs can be used to arrive at meaningful answers to applied data analysis problems.     

Investing in high quality preschool: lessons from an urban setting

Abstract

Large numbers of children of low income families in the United States arrive at kindergarten already far behind their more affluent peers on measures of school readiness. In the absence of any federal preschool policy and amidst alarm about this growing divide, universal prekindergarten (UPK) programs have been launched around the United States, at both the state and local levels, to address the school readiness gap. Invest in Children, a public/private partnership in Cuyahoga County (Cleveland, OH) launched a UPK program of high quality, affordable preschool nine years ago. The program’s creation, implementation and challenges are discussed along with evaluation findings that document its positive impact on school readiness. Lessons learned are discussed in terms of the impact of political and economic shifts, as well as state policy changes, on this local program. The program’s planned expansion and enhancements to program design and evaluation are also described.     

Construction of common interpretive spaces through intertextual loops - How teachers interpret multimodal learning materials

This study draws on several theoretical domains: intertextuality, multimodality, and the pedagogy of multiliteracies. We introduced multimodal textbook materials to eleven experienced teachers and examined, through in-depth interviews, their approach to juxtapositions of literary texts and visual artwork. Our analysis revealed (a) three attitudes toward textbook juxtapositions: unconditional approval, conditional approval, and rejection; and (b) a three-phase pattern of behavior: identifying commonalities, repeatedly comparing texts, and interpreting juxtapositions as intertextual interpretive units. We suggest that enhancing teachers’ awareness of their own thought processes may promote their insight about the contribution of the weaving of visual art into literature instruction.     

Gifted Israeli Students' Perceptions of Teachers' Desired Characteristics: A Case of Cultural Orientation

Gifted students' perceptions of the desired characteristics of teachers of the gifted were assessed from a sample comprised of 404 elementary- and junior high–school Israeli Jewish and Arab students studying in pullout centers. Perceptions were measured using a questionnaire comprising teachers' cognitive, personal, and pedagogical dimensions. Personal characteristics were perceived by both Jewish and Arab students as the most important. Significant effects of culture, gender, and grade level were detected for all three dimensions. We suggest that differences stem from collectivist/individualist cultural orientations and girls' status aspirations. Thus, students' perceptions of teachers' desired characteristics have to be discussed in relation to their cultural background and schooling. A new lens for examining teaching of gifted students is offered, along with practical implications for teacher-certification programs.     

Examination of Critical Features and Lessons Learned for Implementation of a Tier 2 Intervention System for Social Behavior

This article reviews Check-In, Check-Out (CICO; Hawken & Horner, 2003 Hawken, L., & Horner, R. (2003). Evaluation of targeted intervention within a schoolwide system of behavior support. Journal of Behavioral Education, 12, 225–240.[Crossref] , [Google Scholar]) as an intervention within a multitiered system of support. Although literature has emerged demonstrating successful intervention outcomes for a wide range of students (e.g., Campbell & Anderson, 2011 Campbell, A., & Anderson, C. M. (2011). Check-In/Check-Out: A systematic evaluation and component analysis. Journal of Applied Behavior Analysis, 4, 315–326.[Crossref], [Web of Science ®] , [Google Scholar]; Hawken & Horner, 2003 Hawken, L., & Horner, R. (2003). Evaluation of targeted intervention within a schoolwide system of behavior support. Journal of Behavioral Education, 12, 225–240.[Crossref] , [Google Scholar]), insufficient attention has focused on the administrative and organizational systems needed for high-fidelity, sustained adoption of these practices to maximize student outcomes. We address this need by demonstrating how to explicitly and systematically embed CICO into the multitiered system of supports by reviewing data, systems, and practices needed to sustain high-quality Tier 2 interventions such as CICO. One school district's systems implementation data and student outcome data are shared highlighting lessons learned during training, initial implementation, and follow-up related to CICO systems in schools. The article emphasizes the roles of school psychologists as well as the importance of collaboration with other educators in CICO implementation.     

BMI-referenced cut-points for recommended daily pedometer-determined steps in Australian children and adolescents

The purpose of this study was to establish sex-specific criterion-referenced standards for pedometer-determined physical activity related to body mass index (BMI)-defined weight status among youth. We analyzed data from 7-16-year-old boys (n = 338) and girls (n = 337) and used pedometer-assessed physical activity and anthropometric data to derive average steps/day and BMI. Sex-specific criterion-referenced standards for steps/day relating to healthy weight and overweight/obese were determined using the contrasting groups method. Healthy weight children took more steps/day than overweight or obese (boys: 14,413 vs. 12,088, and girls: 12,562 vs. 10,114, respectively; p < .001). The optimal BMI-referenced cut-point emerging flom our sample was 16,000 steps/day for both boys and girls. Our results and those reported elsewhere suggest that youth take insufficient pedometer-determined steps/day to avoid becoming overweight.     

Maximizing your effectiveness

It is of no surprise to readers ofDay Care and Early Education that child care is an issue in today's political arena (Rieken, 1989; Willer, 1990). Many opinion polls, surveys, and interviews have been and are being conducted to gather public opinion regarding child care (Zinsser, 1989). Data are often collected and results presented in scholarly publications, and data are not fully utilized or are not presented in useful format to lay audiences.Sandra S.

Young people’s perceptions of relationships and sexual practices in the abstinence-only context of Uganda

The Ugandan government has been criticised on several grounds for its abstinence-only policies on sexuality education directed towards young people. These grounds include the failure to recognise the multiple realities faced by young people, some of whom may already be sexually active. In the study reported on this paper, students’ perceptions of relationships and sexual practices were analysed to obtain an understanding of how young people construct and negotiate their sexual agency in the context of abstinence-only messages provided in Ugandan secondary schools and at the wider community level. Ten in-depth interviews and six focus group discussions were conducted with students aged 15–19 years (N = 55) at an urban co-educational secondary school. Data were transcribed verbatim and analysed using grounded theory. Findings show that students engage in sexual activity despite their belief that contraception is ineffective and their fears for the consequences. Students’ age, gender, financial capital and perceived sexual desire further increase risk and vulnerability. To improve their effectiveness, school-based sexuality education programmes should support students to challenge and negotiate structural factors such as gender roles and sociocultural norms that influence sexual practices and increase vulnerability and risk.
