School disciplines,social representations,and the construction of the didactics of history,geography, and civics

The author presents a concept of the didactics of history, geography, and civics that seeks to link, through a single dynamic, the civic, political, and social goals of school knowledge with everyday classroom practice and pupils' learning. Two concepts occupy the heart of this construction: those of school disciplines and social representations. The concept of school disciplines addresses the fact that school knowledge is a creation of the school, designed to enable it to achieve the social goals it is assigned. A school discipline is thus a particular combination of goals, content (in the form of shared knowledge), methods, and practices. The concept of social representations is a tool serving to analyze knowledge as theories of the natural and social world, its production, and its reception by the different actors involved.     

Integrating instruction of science,reading, and writing: Goals,teacher development,and assessment

This article describes the interplay of goals, teacher development, and assessment in the context of a yearlong research and development project. The aim of the project was to integrate the teaching of science, reading, and writing processes in a conceptually based, constructivist curriculum for middle school students who read below grade level. A performance-based assessment was designed and implemented to determine the level of student awareness and control over the processes taught during a unit of instruction. Interviews with science teachers and supervisors revealed the important interaction of curricular goals, the performance assessment, and instructional practice.     

Behavioural and emotional strengths of sociometrically popular,rejected, controversial,neglected, and average children

ABSTRACT

Many behavioural and emotional characteristics are associated with children’s peer relationships. The purpose of this study is to examine behavioural and emotional strengths of sociometrically popular, rejected, controversial, neglected, and average children. 773 third-grade children (51% girls) are assessed with a sociometric questionnaire and self-evaluations of their behavioural and emotional strengths and difficulties. Teacher evaluations are also used to assess the children’s academic competencies and behaviour. Univariate analysis of variance (ANOVA) is used to analyse the data. Results indicate that children in the popular status group assess their behavioural and emotional strengths as being better than children in the rejected status group. The behavioural profile of the controversial status group is similar to that of the rejected status group. Children in the neglected status group differ from other sociometric status groups in some behavioural and emotional strengths. Issues pertaining to gender differences are also discussed.     

Biography,Identity, and Inquiry: The making of teacher,teacher educator,and researcher

This is a self-study of my professional and cultural biography and identity, a history which directed me first toward the work of urban teaching and then into teacher education and research into comparative educational issues of racial and national identity. I use this inquiry to demonstrate how biography and identity influences the lived experience of teaching and the researcher's stance. I also examine areas where preservice urban teacher education programs must improve. My personal recommendations describe experiences that would have better prepared me for urban teaching. Suggestions include expanding coursework in the historical, political, and sociocultural influences on urban education and in designing culturally responsive curricula. I also recommend restructuring field experiences to offer richer classroom-based learning opportunities for preservice teachers and extending fieldwork into urban communities. Finally, I suggest ongoing inservice teacher education in learning-community models that respond to educators' context-specific teaching concerns.     

The construction,expression, and consequences of difference in education practice,policy, and research

In this essay, I discuss three key ideas related to the construction and treatment of “difference” in and around schools and schooling. First, just as difference is most commonly located within marginalized populations at the intersections and along the lines of race, disability, social class, national origin, sexuality, sex, language, and religion, such “locating” is done by those socialized and reinforced to view themselves as normal and the norm against which they compare those different from them. Therefore, normalcy operates to maintain positions of superiority for some and inferiority for others. Next, the situation of disability at the intersection of non-dominant identities can be a powerful tool for disrupting normative spaces, practices, and beliefs. Finally, I call for critical action that exposes the negative construction of and consequences of difference in the academy, noting how epistemologies, methodologies, publication outlets and formats, and sentence structures that fall outside what we associate with normalcy, and those who employ them, are also sorted along lines of competence and incompetence, leading to the dismissal or exclusion of disabled scholars, scholars of color, and those scholars engaging in more public praxis outside the academy walls.     

Tracking Financial Aid and Persistence of Women,Minority, and Needy Students in Science,Engineering, and Mathematics

This longitudinal research study focused on persistence and financial aid of women, underrepresented minorities, and needy students majoring in science, engineering, and mathematics (SEM) in a large, public university in a metropolitan area. Beginning in fall 1989, four consecutive freshmen cohorts (n's = 1967, 1679, 1614, and 1924, respectively) were tracked through 1996–97. SEM majors persisted and graduated at higher rates, but took longer to graduate than non-SEM majors. Women, underrepresented minorities, and needy students received more gift aid than other student populations. However, only women had lower departure rates and graduated at higher rates than other SEM student populations. Compared to non-SEM majors, gift aid for SEM majors was more likely to be awarded on the basis of merit rather than need. Average loan indebtedness increased rapidly from 1989–90 through 1996–97 for both SEM and non-SEM majors. Implications of the findings for improved institutional and federal policy are indicated, and further research on the study topics recommended.     

Diagnosis,Remediation, and Locus of Control

The influence of locus of control, diagnosis, and remediation on immediate and retained achievement and attitudes of middle school science students was the focus of this study. Subjects in the experiment were assessed for locus of control and experienced one of three treatments: no diagnosis or remediation; diagnosis with no remediation; or, diagnosis and remediation. Immediate achievement was measured at two points during the experiment, and retention was measured 30 days following the experiment. Diagnosis and remediation proved to be significantly effective in increasing retained achievement. Internal locus of control subjects out-scored external subjects in the areas of both immediate and retained achievement. Whites achieved higher than blacks in retention. Attitudes of all groups tended to be positive. These findings suggest that diagnostic or diagnostic and remedial instruction is an effective means of increasing the retention level of middle school students.

Effects of guidance,sequence, and attribute-treatment interactions on learning,retention, and transfer of hierarchically ordered skills

An investigation was made of the effects of amount of guidance, sequence of instruction, and attribute-treatment interactions on speed of learning, retention, and transfer of ten intellectual skills that form part of a learning hiererchy and which are commonly part of secondary school physics courses. Four clearly-defined instructional methods were used; the methods form a linear scale from least to most guidance. It was found that the numbers of errors made in reaching a criterion performance on the skills decreased as the amount of guidance was increased, but transfer and retention were unaffected. Two sequence styles were used, which were both consistent with the requirement that no skill should be taught before the skills that were subordinate to it in the learning hierarchy. Form of sequence had no effect on speed of learning, retention, or transfer, and there was no interaction between sequence and amount of guidance. A novel method was employed to search for the presence of any interaction between attributes of learners and the amount of guidance. None was found. It is concluded that a maximum of guidance can be used to teach intellectual skills to all learners with no negative effect on retention and transfer. It is suggested that variables other than amount of guidance or sequence are more likely to affect a learner's retention or transfer of a skill. Finally, patterns of retention of skills that are connected in the learning hierarchy were found to be contrary to an earlier result. The patterns suggest that a skill in a learning hierarchy cannot be recalled unless its relevant subordinate skills are also recalled.     

教师工作价值取向与教师管理的三部曲——谋生、职业、事业与顺从、认可、内化

西方学者将工作价值取向划分为谋生取向、职业取向与事业取向三种类型。不同工作价值取向的教师,有不同的工作认识和行为,工作的主动性、幸福感和满意度也有很大差别。因此,他们对教师管理的态度也有顺从、认可、内化之别。鉴于此,在教师管理中,一方面,对不同工作价值取向的教师个体,要实施有针对性的管理;另一方面,对由不同工作价值取向个体组成的教师群体,要逐步引导更多教师由谋生走向职业,再由职业升华到事业,最终实现教师管理的理想境界。

Research,Governance, and Technologies of Openness

Recent policy changes in the European Union have introduced the requirement for publicly funded research to be published in open access. This can be seen as part of a mode of democratic accountability that not only promotes transparency but also, Naomi Hodgson argues, is constituted by visibility and openness. By drawing attention to the way in which the researcher is asked to understand herself in this policy context, Hodgson illustrates how particular technologies of performance measurement and management, and of publication, enter the researcher into this economy of visibility. The understanding of openness as a corrective to the traditional closed access system of publishing and the marketization of academia is challenged, then, in this article, which indicates how these technologies of reading and writing constitute the researcher as a particular figure in the emergent mode of governance.     

Enhancement of self-regulation,assertiveness, and empathy

This study examined the effects of teaching self-regulation strategies and social skills to 40 middle school students in a compulsory secondary education setting, who presented difficulties in self-reflection, self-inquiry, assertiveness, and empathy. A quasi-experimental design with pre- and post-test measurements was employed. Intervention consisted of the performance of tasks, called ‘Portfolio’, related to the criteria skills during the school course. Significant differences between the experimental and the control groups were observed in the measurement of the criteria variables. Results are discussed in terms of the implications concerning how teachers can implement self-regulatory activities in their daily classroom practice to meet the educational needs of students with social problems.     

Comenius,moral and pious education,and the why,when and how of school discipline

ABSTRACT

The present study provides an analysis of John Amos Comenius’s thoughts on moral and pious education, educational governance and school discipline as expressed in Didactica Magna. This is examined from the background of his view of education as a societal phenomenon, the purposes of different categories of knowledge for individual formation and the role of pedagogy in the upbringing of children. Theoretically, this paper expands on Michel Foucault’s ideas about governmentality and discipline, as well as on Henri Lefebvre’s spatial theories. The article argues that Comenius can be viewed as a significant contributor to the early modern shift towards new administrative techniques for school governance, transmitting the mode of disciplinary power into pedogogised and didactic forms. The article contributes to achieving more systematic knowledge for understanding the focused areas of schooling, the concept of discipline and the pedagogic premises of disciplinary practice in an early-modern European educational context.     

Samples of stimuli,responses, and reinforcers: Effect of incongruent sample type,serial position,and mode of presentation

In two matching-to-sample experiments, pigeons’ performance with samples of stimuli (red and green), number of responses (1 and 20), and reinforcers (food and no food) was assessed. Samples of red, 20 responses, and food were associated with the red comparison stimulus, and samples of green, 1 response, and no food were associated with the green comparison stimulus. On interference trials, three sample types were presented on each trial, and two of the samples (congruent) were associated with the correct comparison and the third sample (incongruent), with the incorrect comparison. Performance on interference trials was compared with that on control trials in which either two (Experiment 1) or three (Experiment 2) congruent samples were presented. It was found that presentation of an incongruent sample reduced matching accuracy markedly, and about equally, whether samples were presented successively or in compound. Although the type of sample that was incongruent was without effect, matching accuracy declined strongly as the recency of the incongruent sample increased. Serial position of the incongruent sample also influenced the shape of the retention function on interference trials. Presentation of the incongruent sample either first or second resulted in accuracy decreasing across the retention interval, whereas presentation of the incongruent sample last in the input sequence resulted in increasing accuracy across the retention interval. The theoretical implications of the findings are considered.

Learning,Media, and the Case of Dax Cowart: A Comparison of Text,Film, and Interactive Multimedia

Alternate reality games (ARGs) are a relatively new form of collaborative game that make use of both the virtual and real worlds to engage players in a series of challenges within a compelling narrative. The Alternate Reality Games for Orientation, Socialisation and Induction (ARGOSI) project aimed to use this game format to provide an alternative way to support the student induction process at Manchester Metropolitan University. The ViolaQuest game provided a mechanism for new university students to meet with others, navigate a new city and undertake information literacy induction activities within a purposeful context. The project ran from April 2008 to March 2009, and while the game itself had limited success in terms of student participation and impact, there were many lessons learned in terms of appropriate design and implementation of alternative reality games to support learning. This article describes the evaluation, results, lessons learned and raises a number of questions as to the suitability of ARGs in higher education.     

美英法德俄五国课程表比较

学校教育是被时钟控制的,课程表就是这种控制的表现.我国现行课程中,课程表是学校惟一有权自主决定和安排的,然而限于传统的视野,即使在实行新课程改革的今日,许多学校往往意识不到课程表的价值.然而当我们把目光转向国外的学校时,却发现这个"螺蛳壳"中还是有许多"道场"可做的.本文从课程编制、教与学的组织及课程中的时间安排这三个角度,对五国的课程改革进行分析,希望能为我国的改革提供一些借鉴.     

Globalization, Educational Targeting, and Stable Inequalities: A Comparative Analysis of Argentina, Brazil, and Chile

The present study analyzes educational targeting in Argentina, Brazil and Chile from a sociological point of view. It shows that a ‘logic of induction’ has become the vehicle for anti-poverty education strategies meant to help targeted groups improve on their own. The analysis explores the influence of the global educational agenda, the empirical connection between the logic of induction and the mechanism of emulation, and the territorial aspects of educational inequalities. Emulation plays a main role inasmuch as the logic of induction leads targeted groups to compare their adverse situation with more privileged groups, which actually legitimizes inequalities. A brief statistical summary completes the study, showing that educational inequality has remained unchanged as far as urban–rural ratios (in Brazil and Chile) and regional disparities (in all three countries) are concerned.
