This paper first takes a brief look at the school system and the teaching of biology in Germany. Then a research project is described which is aimed at improving methods of teaching biology. Within the framework of this project, several teaching models are examined and their effectiveness, in both cognitive and affective terms, analysed. This research project includes empirical studies in which more than 2000 school students have been involved. The results of four of these studies will be looked at in detail. The following models were studied and compared: Lab work completed by students compared with lab work demonstrated by the teacher and with pencil and paper lessons. Classroom instruction on the identification of plants compared with outdoor instruction. Lessons using living invertebrates compared with lessons using models, slides and pictures. The effect on the attitudes of students towards AIDS infected children and on their knowledge about AIDS after lessons showing films on the subject compared with lessons on the same subject with no films.  相似文献

Summaries

English

The paper discusses the reasons why students may be deficient in mathematics on entering universities and investigates methods of diagnosis and remedy with the help of illuminative evaluation techniques. The bulk of the paper concentrates on the improvement of manipulative skills and concludes that more deficiencies arise from students having forgotten material which they had learned before than from any other cause, and that deficiencies due to this cause, while readily remediable, can cause great difficulties later, if not remedied early. Deficiencies due to failure of understanding concepts and notation are discussed briefly in an appendix by J. Nuttall.  相似文献
