Peer assessment in university teaching: evaluating seven course designs

Peer assessment is understood to be an arrangement with students assessing the quality of their fellow students’ writings and giving feedback to each other. This multiple‐case study of seven designs of peer assessment focuses on the contribution of peer assessment to the acquisition of undergraduates’ writing skills. Its aim is to arrive at an optimal design of peer assessment. Factors included in this study are: the quality of peer assessment activities, the interaction between students in oral peer feedback, students’ learning outcomes, and their evaluation of peer assessment. Most students took assessing the work of their fellow students seriously, and included the peer feedback in the revision of their work. In most conversations, students provided feedback in an evaluative manner. In others, the interaction was more exploratory. For peer assessment, we recommend a combination of written and oral peer feedback.     

Communities of Public Service Support: Citizens engage in social learning in peer-to-peer networks

New Public Management and bureaucratic models fail to acknowledge the value of peer-to-peer cooperation between citizens as a resource for public service support. Social media enable citizens to create environments for sharing information about public services in Communities of Public Service Support. The success of this model for public service support depends on the availability of communities, the level of active participation, and the information content. This paper presents an empirical study of virtual communities of expats in The Netherlands. Our analysis shows that there is a wide variety of virtual expat communities with a high level of participation and valuable content. We conclude that virtual communities play an important role in public service support since they facilitate social learning between citizens.     

Linguistic analysis of extended examination answers: Differences between on‐screen and paper‐based,high‐ and low‐scoring answers

This small‐scale pilot study aimed to establish how the mode of response in an examination affects candidates' performances on items that require an extended answer. The sample comprised 46 17‐year‐old students from two classes (one in a state secondary school and one in a state sixth‐form college), who sat a mock A‐level English Literature examination. The analysis compared writing produced on screen and on paper to try to uncover any systematic differences between the two modes of delivery. The study considered the linguistic features of the texts produced in each mode, the marks achieved and the views of the participants regarding the use of computers in essay‐based examinations. The study found that the response mode had a small effect on the length of essay produced, in that students using a computer wrote more, and on the type of language used, in that students writing on paper used denser but less varied language. There was very little effect on the marks achieved. Participants expressed a variety of concerns about computer‐based examinations, such as noisy keyboards, assessment of spelling, and unfairness towards those who are less comfortable with the technology.     

Comorbidity of PTSD in anxiety and depressive disorders: Prevalence and shared risk factors

The present study aims to assess comorbidity of posttraumatic stress disorder (PTSD) in anxiety and depressive disorders and to determine whether childhood trauma types and other putative independent risk factors for comorbid PTSD are unique to PTSD or shared with anxiety and depressive disorders. The sample of 2402 adults aged 18–65 included healthy controls, persons with a prior history of affective disorders, and persons with a current affective disorder. These individuals were assessed at baseline (T0) and 2 (T2) and 4 years (T4) later. At each wave, DSM-IV-TR based anxiety and depressive disorder, neuroticism, extraversion, and symptom severity were assessed. Childhood trauma was measured at T0 with an interview and at T4 with a questionnaire, and PTSD was measured with a standardized interview at T4. Prevalence of 5-year recency PTSD among anxiety and depressive disorders was 9.2%, and comorbidity, in particular with major depression, was high (84.4%). Comorbidity was associated with female gender, all types of childhood trauma, neuroticism, (low) extraversion, and symptom severity. Multivariable significant risk factors (i.e., female gender and child sexual and physical abuse) were shared among anxiety and depressive disorders. Our results support a shared vulnerability model for comorbidity of anxiety and depressive disorders with PTSD. Routine assessment of PTSD in patients with anxiety and depressive disorders seems warranted.

Effects of a Problem-based Structure of Physics Contents on Conceptual Learning and the Ability to Solve Problems

A model of teaching/learning is proposed based on a ‘problem-based structure’ of the contents of the course, in combination with a training in paper and pencil problem solving that emphasizes discussion and quantitative analysis, rather than formulae plug-in. The aim is to reverse the high failure and attrition rate among engineering undergraduates taking physics. A number of tests and questionnaires were administered to a group of students following a traditional lecture-based instruction, as well as to another group that was following an instruction scheme based on the proposed approach and the teaching materials developed ad hoc. The results show that students following the new method can develop scientific reasoning habits in problem-solving skills, and show gains in conceptual learning, attitudes and interests, and that the effects of this approach on learning are noticeable several months after the course is over.
