Voices of reform from the classroom: teachers’ approaches to change

Abstract

This paper reports on case studies of three teachers managing an education reform focussed on assessment, during a busy period of curriculum change in an Australia state Participants attended multiple professional development opportunities including a number of state-wide, systemically-facilitated assessment workshops. The most significant finding to emerge, as narratives of change unfolded over a nine- month period, was the diversity of teachers’ approaches to change. All three were insightful about practices that required change and could identify personal and professional attributes that would assist their management of change. All teachers attended the same systemic workshops and all had access to the Education Department’s published literature about assessment. Yet they organised and implemented change in very different ways. Each teacher’s approach was based on personal assumptions about learners and learning, the reform they agreed to implement, and their preferred approaches to incorporating new assessment practices into their existing repertories. Approach taken was a major determinant of experience of change and thus is an aspect of change management important to inservice-providers, teachers and school leaders. The paper concludes with an overview of a PD package designed with the findings of this research project in mind.     

Making a Difference: Using peers to assess individual students' contributions to a group project

Overcoming the potential dilemma of awarding the same grade to a group of students for group work assignments, regardless of the contribution made by each group member, is a problem facing teachers who ask their students to work collaboratively together on assessed group tasks. In this paper, we report on the procedures to factor in the contributions of individual group members engaged in an integrated group project using peer assessment procedures. Our findings demonstrate that the method we used resulted in a substantially wider spread of marks being given to individual students. Almost every student was awarded a numerical score which was higher or lower than a simple group project mark would have been. When these numerical scores were converted into the final letter grades, approximately one-third of the students received a grade for the group project that was different from the grade that they would have received if the same grade had been awarded to all group members. Based on these preliminary findings we conclude that peer assessment can be usefully and meaningfully employed to factor individual contributions into the grades awarded to students engaged in collaborative group work.     

The relationship between inertial measurement unit-derived ‘force signatures’ and ground reaction forces during cricket pace bowling

Abstract

This study assessed the reliability and validity of segment measured accelerations in comparison to front foot contact (FFC) ground reaction force (GRF) during the delivery stride for cricket pace bowlers. Eleven recreational bowlers completed a 30-delivery bowling spell. Trunk- and tibia-mounted inertial measurement units (IMUs) were used to measure accelerations, converted to force, for comparisons to force plate GRF discrete measures. These measures included peak force, impulse and the continuous force–time curve in the vertical and braking (horizontal) planes. Reliability and validity was determined by intra-class correlation coefficients (ICC), coefficient of variation (CV), Bland–Altman plots, paired sample t-tests, Pearson’s correlation and one-dimensional (1D) statistical parametrical mapping (SPM). All ICC (0.90–0.98) and CV (4.23–7.41%) were acceptable, except for tibia-mounted IMU braking peak force (CV = 12.44%) and impulse (CV = 18.17%) and trunk vertical impulse (CV = 17.93%). Bland–Altman plots revealed wide limits of agreement between discrete IMU force signatures and force plate GRF. The 1D SPM outlined numerous significant (p < 0.01) differences between trunk- and tibia-located IMU-derived measures and force plate GRF traces in vertical and braking (horizontal) planes. The trunk- and tibia-mounted IMUs appeared to not represent the GRF experienced during pace bowling FFC when compared to a gold-standard force plate.     

合作体验学习法

合作体验学习法（Tribes Learning Communities）是北美学校教育改革比较成功的一种尝试,打破传统的教师为中心的课堂管理模式,创造以学生为中心的课堂氛围,将课堂重心从教师教转到学生学。本文介绍几种在这样的教学指导思想下的教学策略框架,供课改中正在探索的老师们借鉴参考。     

桑螵蛸脂类提取物对铜绿假单胞菌的抗菌活性和抗生物膜作用（英文）

目的:探究桑螵蛸脂类提取物的成分及对铜绿假单胞菌的抗菌和抗生物膜作用。创新点:中国传统中药桑螵蛸一直广泛应用于肾病的治疗,在抗菌领域未见报道,本实验首次证明桑螵蛸脂类提取物对铜绿假单胞菌有明显的抗菌和抗生物膜作用。方法:采用气相色谱-质谱联用技术,测定桑螵蛸脂质提取物的化学成分及其相对比例。采用纸片扩散法和琼脂平板稀释法观察桑螵蛸脂类提取物对铜绿假单胞菌的抑菌效应并测定最小抑制浓度(MIC)。采用结晶紫染色法和扫描电镜(SEM)进行抑制生物被膜的试验。结论:桑螵蛸脂类提取物中含有16种化合物,最丰富的成分分别是倍半萜类化合物、单萜和微量芳香族化合物。桑螵蛸脂类提取物对铜绿假单胞菌的MIC为4 mg/ml,对铜绿假单胞菌生物被膜的抑制作用明显。     

Radical feminism,humanism and women's studies

As it is not generally understood, radical feminism is first defined in terms of the concept of patriarchy. Feminists themselves now characterize radical feminism as involving sexism, views of the superiority of women over men, and the goal to establish a separate world without men, a gynocracy. Radical feminism is then contrasted with humanism and seen to be antihumanistic. Feminists themselves further claim that Women's Studies in universities and colleges is basically radical feminism. Thus, ironically, such studies which are supported for the purpose of ending sexism are, in fact, creating it. One solution is to establish Women's Studies on the philosophies of the feminists, who are moving toward what I term humanistic feminism.The author has published over twenty books (in numerous languages), ninety-five professional journal articles, regularly lectures in English, German and French at European and American universities. His special areas of research are emotion, philosophical psychology, philosophy of language and philosophy of education (specifically, teaching young people to be critical—five books—on philosophy for children).I wish to thank the following for their comments on an earlier draft of this paper: Dr. Carol McMillan (England), Dr. Ann Johnson (University of Wisconsin), Dr. Karen Kirst-Ashman (University of Wisconsin), Gisa Bohlen (Germany), and Carolyn Lesley Shibles (Wisconsin).     

Differential costs of curricula in Illinois public junior colleges: Some implications for the future

The purpose of this study was to determine and analyze the annual cost of operation including depreciation of movable capital equipment for educating one student in each curriculum of selected community colleges and to show the relationship of costs of vocational-technical curricula to the cost for common baccalaureate oriented curricula.A stratified sample of eight community colleges was drawn from those that had been in operation for at least five years.These data indicate that a majority of the courses offered in highly specialized curricula in both the occupational and baccalaureate categories were more expansive than those courses that were common to a wide variety of curricula.This study supports differential program funding to assure continued development of high quality vocational-technical programs in community colleges.
