Discovering Randomness, Recovering Expertise: The Different Approaches to the Quality in Measurement of Coulomb and Gauss and of Today’s Students

The aim of this paper is to discuss different approaches to the quality (or uncertainty) of measurement data considering both historical examples and today’s students’ views. Today’s teaching of data analysis is very much focussed on the application of statistical routines (often called the ?Gaussian approach” to error analysis). Studies on students’ understanding of measurement however show, that though the majority can be enabled to apply those routines most of the students fail to construct a coherent understanding of the matter. Analysing two historical examples of measurement practice of the time around 1,800 when the statistical approach was established, we point out what often neglected key idea gave rise to the statistical approach to data analysis (the appreciation of randomness in data distribution) and how the emergence of this idea was embedded in a very sophisticated insight on measurement and the nature of measurement data (experimental expertise). These two aspects can vividly be illustrated using the different approaches to data handling of Coulomb and Gauss around the time of 1,800. Gauss’s appreciation of the randomness in data distribution consequently led him to other analytical routines as those employed by Coulomb. This is an important aspect concerning the teaching of the statistical routines of data analysis. However, the deep experimental expertise of both Gauss and Coulomb in both cases prevented an application by rote of some routines and shaped their approaches to very successful instruments of data handling. We therefore argue that both the key idea of randomness as well as an elaborated experimental expertise has to be taken into consideration much more than before by instructors and teachers in order to support the students to construct a coherent understanding on the nature and the handling of measurement data and especially the assessment of their quality.     

The Accessibility and Usability of College Websites: Is your Website Presenting Barriers to Potential Students?

Thirty community college websites were evaluated for compliance with federal web accessibility standards found in Section 508 of the Rehabilitation Act of 1973 (29 U.S.C. 794d). Two typical sites were tested for usability by individuals with visual impairments, individuals with reading-related learning disabilities (LD), and a control group of individuals without disabilities. Ten additional sites were selected for Simulated Target Group usability testing. Testing revealed that less than 1% of pages evaluated met Section 508 web accessibility standards. Over half of the users found the online admissions application process frustrating, and less than a third of all users could complete the online application without assistance. The Simulated Target Group usability testing encountered similar usability issues across the additional 10 community college websites examined. All four evaluation techniques found that community college websites fared poorly in both accessibility and usability. However, many of the issues could be addressed without significant effort.     

Planning Intercultural Interaction: Extending Anxiety/Uncertainty Management Theory

This article responds critically to a recent article by Lemieux and Tighe (Communication Research Reports, 21, 144–153, 2004) in which the authors conclude that recipients of comforting efforts prefer messages that exhibit a moderate rather than high level of person centeredness. It is argued that an erroneous assumption made by Lemieux and Tighe about the status of “receiver perspective” research on the comforting process led to faulty interpretations of the data and unwarranted conclusions about recipient preferences regarding comforting messages. Alternative interpretations of Lemieux and Tighe's data are presented; these are guided by the extensive previous research that has assessed evaluations and outcomes of comforting messages.     

“Why Is This Happening to Me?:” The Attributional Make-Up of Negative Emotions Experienced in Emotional Support Encounters

Weiner's (2000 Weiner , B. ( 2000 ). Intrapersonal and interpersonal theories of motivation from an attributional perspective . Educational Psychology Review , 12 , 1 – 14 . [CSA] [CROSSREF] [Crossref], [Web of Science ®] , [Google Scholar]) attributional model of intrapersonal motivations suggests that attributions influence not only people's emotional experiences, but also their behavioral responses to the events that caused these emotions. The current study investigates the causal dimensions (i.e., stability, controllability, locus) of five emotions (i.e., sadness, helplessness, hurt, fear, anger) people commonly experience when they are distressed and in need of emotional support. Participants (N = 258) were asked to identify an upsetting event and subsequently talk about it with a confederate helper in a five-minute conversation. After the conversation, participants completed attribution and emotion indices scales. The events discussed were coded into nine categories (e.g., death of a relative, college performance/job problems, break-ups). Results suggested that the five emotions possess a unique attributional make-up and are uniquely tied to specific events that were discussed by participants. Implications of the results are discussed in the context of providing emotional support to people who experience distress.     

Expansion policy and the role of agricultural research in Nazi Germany

Agricultural science played a prominent role in Nazi research policy. During the Second World War, German science commandeered research results and materials from occupied Europe. This process advanced individual careers. It also had a decided influence on research practice and problem choice, both during and after the war. This essay explores the significance of wartime developments for an understanding of Nazi policy and the history of agricultural research.     

Friendship stability among students with and without special educational needs

Previous research has shown that students with special educational needs (SEN) have fewer friendships than their peers without SEN. In this longitudinal study, 545 students from primary and secondary schools, including 106 students with SEN, were surveyed at the beginning and the end of the school year. The results show that students with SEN generally have fewer reciprocal friendships and, proportionally, more often nominate students with SEN than students without SEN. The stability of friendships is lower for students with SEN than for students without SEN. Additionally, for students with SEN, same-SEN-status friendships were as stable as cross-SEN-status friendships, whereas for students without SEN friendships with peers without SEN were more stable than those with peers with SEN.     

Increasing employability by implementing a Work-Integrated Learning partnership model in South Africa – A student perspective

In South Africa, 70 per cent of the population is under 35 years old. South Africa has a vision to increase youth employment by focusing on education, training and skills development that will promote employment opportunities. A work-integrated learning (WIL) partnership model was developed to provide students with work experience and to increase their employability. this article presents the research on the perspectives of students subsequent to their WIL experience. the research method consisted of a structured questionnaire with both closed and open-ended questions. The study findings indicated that students were capable of seeking their own WIL placement and that over 90 per cent of students experienced WIL as rewarding, with multiple opportunities for employment. the article adds theoretical value by increasing the WIL body of knowledge from a student perspective, as well as strategic and practical value by presenting the WIL partnership model that may easily be implemented by lecturers in various disciplines across the continent of Africa and beyond to enable students to enter the workplace with confidence.

Inclusive Elite Education in Sweden: Insights from Implementing Excellence Programs into an Egalitarian School Culture

A global demand for excellence programs and elite education for pupils identified as specially gifted has emerged in recent decades. This article provides preliminary insights into the ongoing efforts to integrate special tracks for “the best” with the egalitarian ideal of A School for All, which remains highly influential in the Swedish educational system. Focusing on a government resolution to introduce excellence programs at Swedish upper secondary schools, the official aim of promoting highly gifted students is compared to the policy’s actual implementation. This comparison reveals that Swedish excellence programs are riven with contradictions, satisfying neither the elitist ambitions embedded in their official guidelines nor the egalitarian convictions of educational practitioners.
