Academics’ perceptions of the benefits and challenges of self and peer assessment in higher education

Despite compelling evidence of its potential effectiveness, uptake of self and peer assessment in higher education has been slower than expected. As with other assessment practices, self and peer assessment is ultimately enabled, or inhibited, by the actions of individual academics. This paper explores what academics see as the benefits and challenges of implementing self and peer assessment, through the analysis of interviews with 13 Australian academics. Thematic analysis of our qualitative data identified seven themes of benefits and five challenges. Our academics showed strong belief in the power of self and peer assessment as formative assessment, contrary to past literature which has focussed on the accuracy of students’ marking. This paper therefore brings insights as to not only what academics value about self and peer assessment but also identifies potential inhibitors in practice. Recommendations are made about improving the design and implementation of self and peer assessment in higher education.     

Swiss Elementary School Teachers’ Attitudes Toward Forest Education

This article investigates benefits and challenges of forest education in view of 257 Swiss elementary school teachers (1st–3rd grade), by means of a written questionnaire and 15 in-depth interviews. Two thirds of the teachers carried out forest education during normal lesson hours (mean visits = eight per year). Forests were clearly considered as an educational setting, and especially suitable for the enhancement of personal and social skills. Setting rules was seen as indispensable for successful forest education and a must to communicate to “novice” teachers. Moreover, the didactic of forest education should be implemented in teacher education curricula.     

Alternative Facts and States of Fear: Reality and STS in an Age of Climate Fictions

Minerva - In the decades since the Science Wars of the 1990s, climate science has become a crucible for the negotiation of claims about reality and expertise. This negotiation, which has drawn...     

Acoustic emission monitoring of an eighteenth-century wardrobe to support a strategy for indoor climate management

The on-site monitoring of acoustic emission (AE) has allowed the direct tracing of climate-induced crack propagation in an eighteenth-century wardrobe displayed in the Gallery of Decorative Art in the National Museum in Krakow, Poland. The anti-correlation measuring scheme and frequency filtering allowed very low levels of physical damage to the wardrobe to be detected in spite of the high background noise typical of the museum environment. The total AE energy recorded during two years of monitoring corresponded to a fractured area of 12 mm² or a total crack propagation of 1.2 mm for two10-mm-thick panels. Although the total damage recorded was minute, correlation between the events of fracturing and falls in indoor relative humidity (RH) in winter due to insufficient humidification was evident. The risk of damage, expressed in terms of crack propagation, was quantified as a function of the magnitude of the RH falls of the duration compatible with the response time of the object. The data allow acceptable RH falls to be identified if a conservation professional or a curator selects a ‘tolerable’ yearly propagation of the fracture, in other words the progress of damage considered insignificant.     

Experimental Comparison of Virtual Reality with Traditional Teaching Methods for Teaching Radioactivity

Research at the University of Nottingham has been carried out to investigate the potential of Virtual Reality (VR) for teaching secondary school science. This paper describes the evaluation of VR to teach radioactivity at secondary school level. Evaluation was carried out in a local school and compared directly to the traditional teaching methods currently used in the school to teach radioactivity. Computer experience, computer attitudes, general attitudes and knowledge gained were measured to allow comparisons to be drawn. Individual differences of gender, ability and home computer use were also looked at in relation to the above measures. Results indicated that both ability level and the order in which the conditions were completed significantly affected the attitude scores. High ability students reported higher attitude scores, both overall and for the VR class in particular. As a result of the evaluation study, the Virtual Laboratory has been heavily modified and further evaluation studies were then carried out.
