Mathematics: a female,male or gender‐neutral domain? A study of attitudes among students at secondary level

The aim of the current study is to investigate whether Swedish secondary school students perceive mathematics as a female, male or gender‐neutral domain. A sample of 1300 students in two age groups, 15‐ and 17‐ years, answered a questionnaire and about 50 students participated in interviews. The main part of the inquiry form consists of Who and mathematics, an attitude scale recently developed by other researchers. The results are analysed with respect to gender, school year and study programme. Gendered attitudes were found among considerable minorities. There is a marked tendency to view mathematics as a symbolically male domain: positive aspects are associated with boys and negative aspects perceived as more female. Older students hold more strongly gendered views than younger. Boys in the science programme have the strongest beliefs of mathematics as a male domain.

Impact of inert metal particles flow on aluminium plate

Inert metal explosive,a new kind of explosive,is a mixture of high explosive and inert metal particle.When this kind of explosive is detonated,an inert metal particle flow will be formed by the ex-plosive product driving.To determine the characteristics of the movement of the metal particle flow,a series of aluminium plates were designed to be the targets on which the metal particle flow impacted.The test result was presented and a numerical model was set up to analyze the impact of the high speed inert metal particles on aluminium plate.Based on the numerical analysis,the relationship between the characteristic of the mark on the target plate and the initial condition of the inert metal particles was pro-posed.From the analysis of the impact on target plates,more information about the movement of the metal particles could be reconstructed.

University–School Partnerships in English Pre-service Teacher Education: A Dialogic Inquiry into a Co-teaching Initiative

Evidence has been accumulating for some time about the impact of standards-based education reforms on schools and schooling, but there has been little research investigating the influence of these reforms on university-based initial teacher education (ITE). This article critically inquiries into the effects of these reforms on an ITE co-teaching project where a secondary English teacher in a school was seconded to work for a year as a teacher educator in an Australian university in a praxis-based partnership. Using Cavarero’s framing of ‘who’ and ‘what’ narratives, and Bakhtinian discourse theory, the authors present three autobiographical narratives exploring different perspectives on their experiences in the co-teaching partnership. The article affirms the value of school–university praxis partnerships for speaking back to standards-based reforms, but acknowledges that this speaking back involves complex relational and dialogic work in grappling with institutional and system-wide policies and practices.     

College Student Perceptions of The (In)Appropriateness and Functions of Teacher Disclosure

This study investigated college student perceptions of the (in)appropriateness of instructor disclosures and perceived functions of instructor disclosures. An interpretive analysis of 35 college students identified that family relationships, life experiences and background, and everyday talk and activities were forms of appropriate disclosures; whereas, intimate relationship details, personal problems, personal opinions, and drinking behavior were considered inappropriate topics for instructors to disclose. In terms of the function of instructor disclosures, students perceived that these disclosures worked to humanize instructors, make instructors approachable, and create affect for instructors and courses. Implications and future research are also discussed.     

Parent-teacher conference communication: a guide to integrating family engagement through simulated conversations about student academic progress

Abstract

Teachers regularly communicate with families, yet few candidates are well-prepared for this professional activity. This gap can hinder family–school partnership and pupils’ success. Given that candidates’ opportunities to learn about family engagement (FE) depends on the decisions and values of individual teacher educators, we illustrate how FE can be integrated into an existing educator preparation programme. Specifically, we describe how to design and use simulated parent–teacher conferences (PTCs) to: foster candidates’ conference communication skills; assess their understanding of content knowledge and their ability to plan instruction. Specifically, we designed two simulation tasks that required candidates’ to analyse and respond to a given student assessment profile and then share their interpretation of the information in ways that developed parent–teacher partnership. Modelled after simulation-based medical education, we describe three steps teacher educators can take to integrate simulated PTCs into their existing curriculum. To illustrate how and why simulations impact professional readiness, we also describe the advantages, sequence and psychological processes of simulation training. A sample of candidate profiles across the two tasks are shared to illustrate what candidates take away from their experiences and the kinds of findings faculty may encounter when integrating simulation pedagogy.     

‘And what language do you speak at home?’ Ethnocentrism and cultural openness in teacher–parent interactions in disadvantaged and ethnically segregated schools

ABSTRACT

This article, based on a deep ethnography in schools located in a disadvantaged multicultural context in Geneva (Switzerland), questions the way in which the local school system and teachers comprehend the cultural diversity of students and their parents. Oscillating between recognition and assimilation, teachers publicly adhere to discourses that emphasise cultural diversity, while limiting its expression, especially when a student encounters school difficulties. Teachers’ meetings with parents are significantly influenced by the majority perspective, leaving the parents with little place to express their own needs. Nonetheless, within the conversation, some parents are able to assert practices that differ from those promoted by the host society. Ultimately, it seems that, in the absence of a multicultural position, teachers are limited to adopting hybrid practices that create unease and are evidence of limited understanding of multiculturality.     

Assessment and the co-regulation of learning in the classroom

ABSTRACT

This paper examines the processes of regulation of student learning that are associated with formative assessment in the classroom. It discusses the concept of co-regulation and presents a model of co-regulation developed in a situated perspective on classroom learning. This model conceptualises co-regulated learning as resulting from the joint influence of student self-regulation and of sources of regulation in the learning environment: namely, the structure of the teaching/learning situation, the teacher’s interventions and interactions with students, the interactions between students, and the tools used for instruction and for assessment. Examples of research showing how co-regulation functions are discussed, in particular students’ use of tools for self-assessment and peer assessment, and the role of teacher–student interactions that encourage active student participation in formative assessment.
