Integrating problem- and project-based learning opportunities: assessing outcomes of a field course in environment and sustainability

Improving student competencies to address sustainability challenges has been a subject of significant debate in higher education. Problem- and project-based learning have been widely celebrated as course models that support the development of sustainability competencies. This paper describes a course developed for a professional Master’s program in environment and sustainability that employs such a model. Additionally, the course was designed to offer value-added opportunities by introducing attributes of interdisciplinary training, service learning, academic research, and professional practice. Results from the course assessments by students, faculty, community clients and organizational partners show this model provided a range of learning, professional and practical outcomes for course partners. The value-added benefits include strengthening sustainability competencies and professional skills for students; longitudinal research opportunities for teaching faculty; real-time assessments of farming practices for community clients; and a heightened regional profile for the non-profit biosphere reserve organization supporting course delivery.     

The effect of mindfulness on extinction and behavioral resurgence

In the present experiments, we investigated the effects of mindfulness on behavioral extinction and resurgence. Participants received instrumental training; either they received FI training (Experiment 1), or they were trained to emit high rates and low rates of response via exposure to a multiple VR yoked-VI schedule prior to exposure to a multiple FI FI schedule in order to alter their rates of responding learned during Experiment 2. Participants were then exposed to either a focused- (mindfulness) or an unfocused-attention induction task. All participants were finally exposed to an extinction schedule in order to determine whether a mindfulness induction task presented immediately prior to extinction training affected extinction (Experiment 1) and behavioral resurgence (Experiment 2). During the extinction phase, the rates of responding were higher in the control group than in the mindfulness group, indicating that the mindfulness group was more sensitive to the contingencies and, thus, their prior performance extinguished more readily (Experiment 1). Moreover, rates of response in the extinction components less precisely reflected previous training in the mindfulness group, suggesting less resurgence of past behaviors after the mindfulness induction (Experiment 2).     

The influence of brief stimuli uncorrelated with reinforcement on choice between variable-ratio schedules

Experiment 1 investigated the behavior of rats trained to leverpress on a concurrent variable ratio (VR) 30 VR-30 schedule with a brief, 500-msec, light occurring at the midpoint of the ratio on one of the levers. Higher response rates were recorded on the lever associated with this stimulus, a finding that paralleled the effect produced by inserting primary reinforcement at the midpoint (i.e., by training on a concurrent VR-30 VR-15 schedule). Similar results were found in Experiment 2 using a concurrent VR-20 VR-20 schedule with a 2-sec visual stimulus presented midway through one of the components. In addition, a brief stimulus inserted midway through the VR-20 component of a concurrent VR-20 VR-10 schedule retarded the development of a difference in response rates between the components relative to a VR-20 VR-10 group lacking the signal. In Experiment 3, multiple VR VR schedules were used. Again, the response rate was higher in the component that had the added stimulus or, for a second group of subjects, on the component with the smaller response requirement. Probe-choice trials revealed a preference for the component that generated the higher rate in both groups. Presenting a stimulus partway through a ratio appears to reduce the effect on response rate and choice of a large ratio value.     

Conceptions of literacy in primary and secondary school teachers

Recently, teachers have been described as lacking an organised and consistent understanding of how children acquire literacy. Arguments about falling standards have been aired in the media, and links drawn between methods currently in favour in UK schools, and an apparent failure of children to acquire ‘basic skills'. Proposals have now been made by the Department for Education which give greater prominence to more structured, skill-based primary teaching which, it is claimed, will raise standards and better prepare children to meet the demands they face as they move into secondary school. This study analyses teachers’ conceptual maps of literacy teaching as the preliminary phase of a research programme aimed at describing and enhancing pupils’ functional use of literacy across the curriculum. The analysis is based on a four-quadrant model of adult-child proximation. Using a questionnaire format, important similarities and contrasts were found between the views of primary and secondary teachers. However, the study does reveal that teachers have complex models of literacy which underpin their work and do not adhere to simplistic, uni-dimensional methods.     

A perplexed story

This piece of life‐story—or, to give it its grand title, auto‐ethnographic research—owes its initial impetus in becoming a written project to a photograph someone took of me in a London secondary school staffroom early on in my teaching career. The young man in the photograph peers out at me from my office wall. Sometime last year, he began to compel me to dig around in filing cabinets for the journals, occasional poems and other dusty relics of a teaching life; it seems he has helped me to recollect the social and historical experiences that have affected my development.     

Evaluating impact from research: A methodological framework

BackgroundInterest in impact evaluation has grown rapidly as research funders increasingly demand evidence that their investments lead to public benefits.AimsThis paper analyses literature to provide a new definition of research impact and impact evaluation, develops a typology of research impact evaluation designs, and proposes a methodological framework to guide evaluations of the significance and reach of impact that can be attributed to research.MethodAn adapted Grounded Theory Analysis of research impact evaluation frameworks drawn from cross-disciplinary peer-reviewed and grey literature.ResultsRecognizing the subjective nature of impacts as they are perceived by different groups in different times, places and cultures, we define research impact evaluation as the process of assessing the significance and reach of both positive and negative effects of research.Five types of impact evaluation design are identified encompassing a range of evaluation methods and approaches: i) experimental and statistical methods; ii) textual, oral and arts-based methods; iii) systems analysis methods; iv) indicator-based approaches; and v) evidence synthesis approaches.Our guidance enables impact evaluation design to be tailored to the aims and context of the evaluation, for example choosing a design to establish a body of research as a necessary (e.g. a significant contributing factor amongst many) or sufficient (e.g. sole, direct) cause of impact, and choosing the most appropriate evaluation design for the type of impact being evaluated.ConclusionUsing the proposed definitions, typology and methodological framework, researchers, funders and other stakeholders working across multiple disciplines can select a suitable evaluation design and methods to evidence the impact of research from any discipline.
