Personal Backgrounds of Effective Teaching

Planning time for giving students effective feedback is an important and challenging aspect of the teaching and learning process. In our article we describe and analyze how we engage students as partners in providing formative feedback in time for students to modify their own thinking or behavior to improve learning. We have found ways to provide formative feedback more frequently and to involve students in providing effective formative feedback to each other. The four techniques we describe are the following: a) three-color group quiz with feedback on product, process, and progress; b) midterm student conferencing; c) shared revision of student generated questions and statements; and d) timely feedback using collaborative assignment blogs. These techniques give feedback in time for revisions to occur, provide scaffolding for learners, inform instruction, and most importantly, involve students as partners in assessment. These pedagogical strategies show that the resulting benefits of improved instruction, enhanced student learning, and better student products are worth the time and effort and contribute to a productive classroom climate where the focus is on learning more than on grading. Formative feedback involving students as partners is a key strategy to enhance the teaching and learning process.     

The development of a perceived masculinity scale

This essay posits that masculinity can be usefully understood from a communication perspective, and it specifically defines masculinity as a social and symbolic construct. In this view, the meanings and associations attributed to masculinity are a product of the enduring images and characteristics people have ascribed and assigned to men in groups over time. Based upon a survey of contemporary published research regarding masculinity, it is concluded that masculinity is now a multidimensional construct which attributes ten traits to people viewed as masculine which are examined in terms of: (1) physiological energy; (2) physical characteristics; (3) gender‐related sociocultural roles; (4) idealized gender; (5) gender preferences; (6) subjective gender‐identity; (7) gender‐related age identity; (8) gender‐related racial and national identities; (9) lust; and, (10) male eroticism. Specific questionnaires used to measure these dimensions are reviewed, and based on the responses of 562 subjects, the reliability and validity of one of these questionnaires is examined in detail. The essay concludes by recommending the use of the Perceived Masculinity Questionnaire 47, and it outlines some of the uses that can be made of a Perceived Masculinity Scale, especially some potential classroom uses.     

磁场对单电子量子双环基态能量E_((0,0))的影响

给出了单电子量子同心环基态能量E(0,0)随磁场和势垒的变化规律,并对变化规律进行分析.结果表明,单电子量子同心环基态能量随磁场增大而增大,由于磁场的存在,原来的基态能级分裂成三个能级.由于量子同心环中势垒的存在,使得单电子量子同心环基态能量增大,基态能量随势垒的增大而增大.

Participatory capital: Bourdieu and citizenship education in diverse school communities

A priority toward creating ‘active’ citizens has been a feature of curricula reforms in many income-rich nations in recent years. However, the normative, one-size-fits-all conceptions of citizenship often presented within such curricula obscure the significant differences in how some young people experience and express citizenship. This paper reports on research that explored the citizenship perceptions and practices of New Zealand social studies teachers and students from four diverse geographic and socio-economic school communities. Attention was drawn to the scale of their citizenship orientations and participation (local/global). Drawing on Bourdieu’s conceptual triad and his species of capital in particular, the author posits that the differences observed between school communities can be usefully explained by a concept of participatory capital. The paper concludes with some reflections on the implications for young people who fail to access the ‘symbolic’ global participatory capital associated with much contemporary citizenship education.
