This paper presents an integrated view of the ideas and conceptual problems of high school students with respect to the cell, its processes, structure and relation to the functions of multicellular organisms. The theme of cell has divided into eight topics, with a questionnaire for each topic. In these topics, different levels of representation and understanding are distinguished between general considerations about plants and animals, those connected with processes at organ and system levels and, finally, the level of cell processes. Data from 1200 students were analysed. Results show that students have an analogical mechanism that establishes an isomorphism between the representation of the functioning of multicellular organisms of cell processes. A series of problems in understanding was also shown. Results imply that these problems are mainly due to students' lack of differentiation between some processes at organism and organ level, and have important implications for learning this subject. Finally, some suggestions are made for teaching. 相似文献

This paper draws upon a broader piece of research on assessment in higher education, particularly focusing on issues regarding the fairness and effectiveness of the assessment methods and their implications for the learning process. The perceptions of undergraduate students are analysed taking into account the effectiveness and fairness of both traditional and learner-centred assessment methods, as well their influence on the learning process. In total, 624 students participated in this study in five Portuguese Public Universities in different areas of knowledge and programmes. Data were collected through questionnaires. Findings suggest that assessment is seen as more effective and fairer when it is done through the use of learner-centred assessment methods rather than by traditional assessment (e.g. written tests or exams). The students also claim that they devote more time to study when assessment is performed through learner-centred assessment methods than by traditional ones. The most used assessment methods are written tests and oral presentations in group. However, differences in the programmes were identified as well as differences according to gender. Implications of the findings for assessment and for the teaching and learning process are discussed. 相似文献
