From Findings to Theories: Institutionalizing Social Informatics

We focus here on the history, status, and future of social informatics. In doing this we build on the visionary work of the late Rob Kling. Social informatics research contributes insights and perspectives to the study of computing in our society that other approaches do not. We make the case that social informatics is on its way to becoming a scholarly institution: accepted as one of the several approaches to study computing, and in particular, the approach best suited to engage on computerization. In making this case, we highlight the value of social informatics, summarize its principles and common findings, point to current work and issues, illustrate the three perspectives through which to pursue this scholarship, and identify several current activities remaining for social informatics to institutionalize.     

One- or Two-Legged Standing

To highlight the capacity of one- and two-legged standing protocols when assessing postural behavior induced by a rigid ankle orthosis, 14 healthy individuals stood upright barefoot and wore either an elastic stocking on the preferred leg or a rigid orthosis with or without additional taping in one- or two-legged (TL) conditions. Traditional center-of-pressure (CP) measures were evaluated for the total two-feet resultant CP and under the feet (plantar CP). Focusing on the plantar CP displacements under the leg fitted with the various orthoses demonstrated particular postural behaviors for traditional parameters with main effects along the mediolateral axis. Only the TL protocol showed the limiting effects of the rigid shells on the inversion-eversion movements in healthy individuals.     

An improvement index to quantify the evolution of performance in running

Abstract

Improvements in track and field sports have been attributed to factors such as population increase, drugs and new technologies, but previous research has found it difficult to distinguish the contributions from specific influences. Here it is shown how this is possible by means of a performance improvement index based on useful work done combined with modelling of the annual top 25 performances. The index was set to 100 in 1948 and showed that, by 2012, it had increased in running events to between 110.5 and 146.7 (men’s 100 m and marathon). Underlying global effects accounted for the majority of all improvements (16.2 to 46.7) with smaller influences attributable to an influx of African runners (3.6 to 9.3), and a 4 -year oscillation that arose from staging of the Olympic Games (±0.2 to ±0.6). Performance decreased with the introduction of compulsory random drug testing (?0.9 to ?3.9) the World Anti-Doping Agency (WADA; ?0.5 to ?2.5) and fully automated timing (?0.6 to ?2.5). Changes in elite sporting performance since the 1890s are attributable to societal changes caused by the industrial revolution and globalisation superimposed on millennia of human evolution.     

The White British‐Black Caribbean achievement gap: Tests,tiers and teacher expectations

A recent analysis of the Longitudinal Study of Young People in England (LSYPE) indicates a White British–Black Caribbean achievement gap at age 14 which cannot be accounted for by socio‐economic variables or a wide range of contextual factors. This article uses the LSYPE to analyse patterns of entry to the different tiers of national mathematics and science tests at age 14. Each tier gives access to a limited range of outcomes with the highest test outcomes achievable only if students are entered by their teachers to the higher tiers. The results indicate that Black Caribbean students are systematically under‐represented in entry to the higher tiers relative to their White British peers. This gap persists after controls for prior attainment, socio‐economic variables and a wide range of pupil, family, school and neighbourhood factors. Differential entry to test tiers provides a window on teacher expectation effects which may contribute to the achievement gap.     

Evaluating Comparative Judgment as an Approach to Essay Scoring

ABSTRACT

As an alternative to rubric scoring, comparative judgment generates essay scores by aggregating decisions about the relative quality of the essays. Comparative judgment eliminates certain scorer biases and potentially reduces training requirements, thereby allowing a large number of judges, including teachers, to participate in essay evaluation. The purpose of this study was to assess the validity, labor costs, and efficiency of comparative judgments as a potential substitute for rubric scoring. An analysis of two essay prompts revealed that comparative judgment measures were comparable to rubric scores at a level similar to that expected of two professional scorers. The comparative judgment measures correlated slightly higher than rubric scores with a multiple-choice writing test. Score reliability exceeding .80 was achieved with approximately nine judgments per response. The average judgment time was 94 seconds, which compared favorably to 119 seconds per rubric score. Practical challenges to future implementation are discussed.     

The role of powerful pedagogical strategies in curriculum development

Despite the frenetic pace of curriculum change in England and Wales it is highly questionable to what extent classrooms have changed since the inception of the National Curriculum, as little attention has been paid to teacher development. This article describes a human-scale approach to professional and curriculum development that relies upon powerful pedagogical strategies. The characteristics and popularity of these strategies are described. The model developed in the study of Effective Teachers of Numeracy (Askew et al., 1997) is used to explain how the use of the strategies can lead to professional and curriculum development. Particular attention is paid, through the reflective accounts of teachers who have used the strategies, to the role of pupil response in accelerating change. Finally the article discusses the way in which the strategies accord with much of what is known about how teachers plan.     

Developing online problem‐based resources for the professional development of teachers of children with visual impairment

This article presents a summary of the results from phase 1 of a two‐phase research project. Drawing on the principles of problem‐based learning (PBL), the aims of phase 1 were to design, develop and evaluate a set of flexible online teaching resources for use within a virtual learning environment. Participants in the project (n = 10) were volunteers from students registered on a two‐year distance education programme of study for specialist teachers of children with visual impairment. Two case scenarios were developed for the project, each of which was based around a fictitious support service for teachers of children with visual impairment. Following a campus‐based study day, the participants were assigned to one of two ‘PBL Activity Groups’ and completed a series of tasks within each case scenario. Participation in the project was supported by members of the Project Team over a period of one semester, following which participants were asked to provide feedback through an online questionnaire. A summary of the feedback is presented, and key findings discussed. The results suggest that, with appropriate resources, adequate preparatory training and effective tutor support, online PBL can be an effective method for supplementing the continuing professional development of specialist teachers studying through distance education.     

The positions of primary and secondary schools in the English school field: a case of durable inequality

In interviews as part of a research study of structural reform in England, some tension between primary head teachers and their secondary peers was evident. This was symptomatic of a long-standing difference in status between the two phases. At a time when relations between stakeholders in local systems are subject to change, we seek to understand anew why that might be the case and how the tension we found was evidence of a current difference of power within interactions between representatives of the phases. We analyse differences of size, resources, workforce, pedagogy and history, and how they have resulted in different, and differently valued, practices and professional identities. We explore how attributes of the two phases have been counterposed and how, in complex interaction with wider discourses of politics, gender and age, this process has invested the differences with meanings and values that tend to relegate attributes associated with primary school. By focusing on the activation of cumulative inequality in interactions, we contribute a complementary perspective to studies of perceived relative status and highlight the implications for understanding school positioning in local arenas as the role of local authorities is reduced.
