In this paper we explore the influence of students’ personalized notion of ‘small’ numbers based on real life experiences
on their understanding of limits. Tests were conducted on two samples of students. The first sample, consisting of students
in the XII grade, had been taught limits using an informal approach (i.e., without recourse to the definition) and the second sample, consisting of first year undergraduates, had been taught the formal definition of limits. Our research points out that most students in both samples round off to zero such ‘small numbers’ while evaluating limits wherever such numbers might occur because they perceive
limit as a process of approximation. 相似文献

The discussion of issues relating to academic dishonesty in the UK higher education sector has become increasingly intense in recent years and has often been subject to the media spotlight. This study examines the policies, procedures and penalties at law schools across the UK when dealing with allegations of plagiarism. Data were obtained in two stages via questionnaires and structured interviews with members of staff. The considerable degree of diversity which emerges is discussed and the possible implications of such diversity are examined. 相似文献

Many mathematics departments have instituted transition-to-proof courses for second semester sophomores to help them learn how to construct proofs and to prepare them for proof-based courses, such as abstract algebra and real analysis. We have developed a way of getting students, who often stare at a blank piece of paper not knowing what to do, to start writing proofs. This is the technique of writing proof frameworks, which is based on the logical structure of the statements of the theorems and associated definitions. Also, in order to unpack the conclusion and know what is to be proved, students need definitions to become “operable.” 相似文献
