Defensive burying in rats and hamsters     

Karen V. Whillans  Sara J. Shettleworth 《Learning & behavior》1981,9(3):357-362

Hooded rats and golden hamsters were shocked by one of two prods in a chamber with a sawdust-covered floor. Rats buried the prod through which they had been shocked, but hamsters displayed no burying behavior. Hamsters may not have buried the prod because they could not perform the required motor pattern. However, hamsters can carry and pile food pellets. Therefore, in a second experiment, rats and hamsters were shocked in a chamber with wooden blocks on the floor. Rats piled blocks around the prod through which they had been shocked, but hamsters did not. The third experiment established that, like rats, hamsters can associate a prod with shock in one trial, since they showed differential avoidance of a prod through which they had been shocked. Since hamsters are nonsocial and rats are social, these results are consistent with suggestions that burying sources of aversive stimulation evolved as an altruistic behavior.  相似文献   

An examination of the instruction provided in Australian essay guides for students’ development of a critical viewpoint     

Sara Hammer 《Assessment & Evaluation in Higher Education》2017,42(7):1069-1081

The argumentative essay has endured as a popular form of university assessment, yet students still struggle to meet key intended learning outcomes, such as those associated with critical thinking. This paper presents the results of a study that examines the instruction provided by Australian essay writing guides to support students’ development of a questioning, critical viewpoint. Thirty publically available guides were chosen from a range of university types, and sourced from central student learning units and humanities disciplines. Findings of this documentary analysis show that some guides provide too little context for essay writing as an academic practice, and conceptualise definitional, instructional and procedural aspects of the task in ways that may not align with intended outcomes. The conclusion indicates a need for further research about the teaching of argumentative essay writing.  相似文献   

Socialisation into Teaching: the research which lost its way     

Paul Atkinson  Sara Delamont 《British Journal of Sociology of Education》1985,6(3):307-322

The paper argues that in recent years sociologists have neglected the processes of occupational socialisation of leaching, despite research interest in everyday life in other educational settings. Shortcomings in the extant research on teacher socialisation and in the wider literature on professional socialisation are detailed to explain the lack of intellectual interest in teacher socialisation. Finally, the paper offers some potential lines for the development of research on teacher socialisation.
