This paper considers a range of factors that may contribute to an unwillingness or inability of teachers to participate in the teaching of biology through fieldwork. Through a synthesis of the views of both pre-service teachers in training and primary school teachers in practice we explore the relative importance of a wide range of potential barriers and potential responses to them in the context of the wider literature. We conclude that although fieldwork may be impeded by the interaction of a wide range of individual barriers, including an individual's predisposition towards the outdoors, it is possible to group interacting barriers into two main areas: school culture and teacher confidence. It is also apparent that barriers may assume different levels of significance when considered in general terms rather than when applied to a particular context and that the significance of barriers may change through time. Encouragingly, we have also shown that in-service teachers have a willingness to overcome these barriers.

Hypertrophy of the sciatic nerve occurred after above-knee amputation in young patients. This finding differed from atrophy of the nerve that has been reported previously in older patients.

It is widely held among biology teachers that fieldwork is valuable, but little is heard about students' perception of fieldwork or about the reasons for their liking or disliking fieldwork. This paper uses data from students to explore the hypotheses (1) that biology students with a positive perception of fieldwork have a less positive perception of laboratory work and vice versa and (2) that perception of fieldwork is related to demographic/personal factors and/or to pre-university perceptions and experience of fieldwork. Numeric indices of appreciation of biology field and laboratory work (I field and I lab ) were determined using questionnaire information from 54 students. I field and I lab were positively correlated and there was no evidence of polarization of views; the problem that some students have a poor perception of both needs to be addressed. Mature students had a more positive view of fieldwork than 18-20-year-olds. However, regression analysis of I field against principal components suggested that demographic/personal factors had relatively little overall influence (, 20%) on appreciation of fieldwork. Perception of fieldwork at university was related to the rank given to fieldwork when choosing a university course. However, students who had participated in pre-university fieldwork did not have a more positive perception of university fieldwork; although students who recalled a worst memory of pre-university fieldwork had a less positive perception of fieldwork at university. The seeming mixed relevance of pre-university fieldwork suggests that the relationship between perception of fieldwork undertaken at university and quality of pre-university fieldwork is an area for future research.
