Intuition in Using Nominal Variables for Prediction

The notion of independence between two nominal variables is typically introduced through the use of chi‐square analysis of contingency tables, while the topic of prediction of one nominal variable from a second nominal variable using optimal prediction to the mode is often omitted. Through the use of a questionnaire, this article indicates that there is considerable confusion among students on the difference between the concepts of independence and prediction, and remedies are suggested.     

Getting Inside the Black Box: Examining How the Operation of Charter Schools Affects Performance

In recent years, a series of articles have examined the performance of charter schools with mixed results. Some of this research has shown that charter school performance varies by charter type or the age of the school (Bifulco &; Ladd, 2006 Bifulco, R. and Ladd, H. 2006. The impact of charter schools on student achievement: Evidence from North Carolina. Education Finance and Policy, 1: 50–90. [Crossref], [Web of Science ®] , [Google Scholar]; Buddin &; Zimmer, 2005 Buddin, R. and Zimmer, R. 2005. A closer look at charter school student achievement. Journal of Policy Analysis and Management, 24: 351–372. [Crossref], [Web of Science ®] , [Google Scholar]; Hanushek, Kain, &; Rivkin, 2002 Hanushek, E. A., Kain, J. F., &; Rivkin, S. G. (2002). The impact of charter schools on academic achievement. Cambridge, MA: National Bureau of Economic Research. Retrieved May 19, 2006, from http://http://www.nber.org/～confer/2002/hiedf02/KAIN.pdf  [Google Scholar]; Sass, 2006 Sass, T. R. 2006. Charter schools and student achievement in Florida. Education Finance and Policy, 1: 91–122. [Crossref], [Web of Science ®] , [Google Scholar]). However, this research has not examined the school attributes that lead to high- or low-achieving charter schools. In this article, we examine how student achievement varies with school operational features using student-level achievement and survey data for charter and a matched-set of traditional public schools from California. We did not find operational characteristics that were consistently related with student achievement, but we did identify some features that are more important at different grade levels or in charter schools versus in traditional public schools. We also examined the relationship between greater autonomy within schools, which is a major tenet of the charter movement, and student achievement and found very little evidence that greater autonomy leads to improved student achievement.     

The Structure of Scientific Arguments by Secondary Science Teachers: Comparison of experimental and historical science topics

Just as scientific knowledge is constructed using distinct modes of inquiry (e.g. experimental or historical), arguments constructed during science instruction may vary depending on the mode of inquiry underlying the topic. The purpose of this study was to examine whether and how secondary science teachers construct scientific arguments during instruction differently for topics that rely on experimental or historical modes of inquiry. Four experienced high-school science teachers were observed daily during instructional units for both experimental and historical science topics. The main data sources include classroom observations and teacher interviews. The arguments were analyzed using Toulmin's argumentation pattern revealing specific patterns of arguments in teaching topics relying on these 2 modes of scientific inquiry. The teachers presented arguments to their students that were rather simple in structure but relatively authentic to the 2 different modes. The teachers used far more evidence in teaching topics based on historical inquiry than topics based on experimental inquiry. However, the differences were implicit in their teaching. Furthermore, their arguments did not portray the dynamic nature of science. Very few rebuttals or qualifiers were provided as the teachers were presenting their claims as if the data led straightforward to the claim. Implications for classroom practice and research are discussed.     

Persons with Drug Addiction as Knowledge Providers: Their Contribution to Social Work Education

Social work students' stereotypical perceptions of excluded populations could be decisive in the way they treat those who are excluded. In an attempt to change such perceptions and enhance knowledge about how to work with an excluded population, a dialogue-in-class model was implemented between students of social work in Israel and persons with drug addiction. The experiences of 292 students were evaluated by utilizing a semi-structured instrument. The findings indicated the potential of this model (in which representatives of an excluded population are the knowledge providers) to expand and enrich the unidimensional and stereotypical way in which students may perceive persons with drug addiction. The participants drew implications for future practice with excluded populations. These included both the importance of coming to a fuller understanding of the unique difficulties and needs of each person and the necessity of overcoming barriers hindering connection with persons in excluded populations, thus reducing their sense of exclusion.     

Making the difference with active parenting; forming educational partnerships between parents and schools

Although parental involvement is often a priority on the quality agenda of schools for primary and secondary education, it is still not usual to involve parents as an educational partner in the actual learning process of their child. Rather than adopting an open approach, teachers tend to tell parents what they should do or keep them at a safe distance. At the same time, parents are increasingly becoming better informed, more critical and thus are more strongly positioned towards school. They address teachers more directly in case of problems or disappointing results of their child. Clearly, this might lead to a negative impact on the mutual relationship especially when parents’ emotional involvement conflicts with a professional and detached attitude of teachers. Based on the results of several studies that provide ample evidence that parental involvement in the learning process can improve learning outcomes, it is argued that there is much to be gained in forming educational partnerships between parents and schools. Different dimensions of active parenting are discussed, as well as prerequisites for successful implementation.     

Dispositions Toward Critical Thinking: The preservice teacher's perspective

This study examines the critical thinking (CT) dispositions of 202 preservice physical education students in the US. All were juniors or seniors and enrolled in physical education secondary teaching methods classes. Results provided evidence of a positive inclination toward CT on six of seven subscales and the total score of the California Critical Thinking Dispositions Inventory (CCTDI). When compared with other university populations, the preservice physical education sample generated higher scores than community college students, but were generally outscored by students from a private 4-year university cohort. Knowledge of the CCTDI data can be used to assist physical education teacher educators as they prepare teachers capable of fostering CT in their students.     

Towards educational inclusion in a contested society: from critical analysis to creative action

This paper is written by democratic educators who stand for the idea that is it worth developing, through classrooms and schools, a socially just (egalitarian), anti‐discriminatory society where interdependent relationships are valued. This paper significantly develops some of the ideas explored in the authors’ earlier contribution concerned with progress in Northern Ireland towards educational inclusion, and how this might more effectively advance in a post‐conflict transforming society. In particular, the paper poses the ‘so what’ question, and it responds by exploring the practical implications of six key ideas thought essential for transforming learning environments supportive of cultural diversity, equity and excellence for all. In addition, it includes examples of how school staff, along with collaborating partners, might utilize these key principles in order to facilitate school improvement.
