Twenty-eight geography students were questioned about how they had prepared an essay about Africa and their answers were related to their essay marks. Each essay was marked by one of 9 postgraduate tutors and the researcher. Aspects of the students' essays, such as length and number of main points, were analysed and related to the students' marks. Tutors said that, in order to qualify for a high grade, students should have: answered the question, made a readable presentation, a logical presentation, and showed evidence of wide reading. These criteria were positively correlated with the students' marks and consistent with the comments which the tutors wrote on the students' essays. In this study, the students attained higher marks if they: included more main topics in their essays, had a readable writing style, produced more drafts for their essays, and cited more references. The results are discussed in relationship to advice about essay-writing in study manuals and other ways of helping students to improve their essay-writing.Students' essay-writing has been investigated from many different points of view (Nightingale 1988) and yet there are very few studies about students' preparation strategies or which strategies lead to success. Researchers may have been discouraged by methodological difficulties, such as: classifying and defining relevant concepts, measuring these concepts, evaluating alternative strategies, and taking into account different disciplines and students; to say nothing of the fact that essay marking is subjective, rather than objective. These and other methodological difficulties have been touched upon by Humes (1983) and Entwistle and Wilson (1977). However, such difficulties must be surmounted if we are to understand students' essay-writing, and although early studies are likely to be relatively crude, they are a necessary part of progress.Pioneer research in student essay-writing was reported by Branthwaite, Trueman, and Hartley in 1980. These researchers asked 82 psychology students in their first, second or third year at Keele University, England, to complete questionnaires about their preparation of one or two essays. Answers were related to the students' essay marks, but their essays were not analysed. Questions about preparation related to: time spent on essay preparation, number of sources used, planning, revising, and what marks the students expected from their tutors. The seven tutors who marked the students' work were asked about their marking criteria. The main finding from the study was a mismatch between the assessment criteria of students and their tutors. There was no significant relationship between marks and year of study, although there was a tendency for more experienced students to gain higher marks.The second year students got higher marks if they had prepared rough drafts for their essays, and there was a tendency for all students to get higher marks if they had made written answer plans before writing their essays. The most significant relationship between strategy and ...
