Factors predictive of black students' communication with the administration and students at a predominantly white university

Black students' interaction with a predominantly white university's administration, faculty, and students appears to be a central issue in current study of black student success in college. This study examined personality and situational factors predictive of black students' communication with such a university's administration, faculty, and students. The development of an instrument describing environmental and social concerns of black students demonstrated reasonable predictive validity of communication with the administration and white students. Feelings about the social environment and tendencies of communication anxiety were among the strongest predictors of black students' communication.     

How Web 2.0 is Changing the Nature of Museum Work

Abstract George Brown Goode, a former Assistant Secretary of the Smithsonian in the late 1880s, said that the nature of museum work is not only knowledge creation, but also knowledge dissemination, and, ultimately, learning: “The museum likewise must, in order to perform its proper functions, contribute to the advancement of learning through the increase as well as through the diffusion of knowledge” (1991, 337). Elaine Heumann Gurian noted that: “The use of the Internet will inevitably change museums. How museums respond to multiple sources of information found on the Web and who on staff will be responsible for orchestrating this change is not yet clear. The change, when it comes, will not be merely technological but at its core philosophical” (2010, 95). The catalyst for this change—and for accelerating the pace of change—is Web 2.0.     

Young people's views of sex education: gender,information and knowledge

This paper derives from research that had the aim of understanding more about adolescents' views of sex education and adolescent sexuality. The data are taken from three separate pieces of research conducted in 1984, 1998 and 2003. This paper presents data about gender, information and knowledge relating to sexuality. It seeks to demonstrate that attitudes to information and knowledge vary significantly with gender. The data suggest that many adolescents we studied were offered different access to information about sex and sexuality in their families. The argument is that this has impact on the sources of information that they rely upon and prefer. We investigate the underlying issues about the ways boys obtain not only information about sex, but also their attitudes to sexual encounters. Sources of information and counselling about sexuality varied with gender. Boys and girls were exposed to different kinds of experience, in which information about sexuality and messages about desire also vary. Home and intimacy with parents, especially mothers, is important for many, although not all, girls in a way it is not for boys. This indicates a picture of boys learning about sex and sexuality in ways that by and large do not include adults, or more especially trusted adults, and where there appears to be some elements of exclusion from the family. This has important implications for sex education programmes, and may offer us insights into why the boys resist school sex education work.     

Constructive Interference: Wikis And Service Learning In The Technical Communication Classroom

Four service-learning projects were conducted in technical communication courses using wikis. Results confirm previous findings that wikis improve collaboration, help develop student expertise, and enact a “writing with the community” service-learning paradigm. However, wikis did not decenter the writing classroom as predicted by previous work. Instructors using wikis to scaffold client projects should calibrate standards for evaluation with students and client, and they may need to encourage clients to stay active on the wiki.     

“The Coat Traps All Your Body Heat”: Heterogeneity as Fundamental to Learning

This article explores heterogeneity as fundamental to learning. Inspired by Bakhtin's notion of heteroglossia, a design team consisting of an experienced classroom teacher and 2 researchers investigated how a class of 3rd and 4th graders came to understand disciplinary points of view on heat, heat transfer, and the particulate nature of matter. Through a series of planned and unplanned encounters, official versions of the Second Law of Thermodynamics and the particulate view of matter were juxtaposed with varied domains of experience of heat transfer and phase change in water. We analyze the children's discourse to examine how they populated these phenomena with meaning and what they learned in the process. We conclude by describing key principles and a conundrum that emerged from this research.     

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.
