高师环境教育的途径与模式

根据我国环境问题现状的紧迫性．我们认为在环境教育中应充分发挥高等师范院校“工作母机”的作用,以带动学校教育、社会教育和家庭教育全面而有效地发展。在高师环境教育中,应结合专业教育和素质教育,建立不同层次的教育实施体系,遵循“专业──专业渗透──素质提高”的基本模式,使环境教育工作适应可持续发展的战略要求。

THE UNIONIZATION OF TEACHERS IN TURKEY

The beginnings of teacher unionization in Turkey go back to 1921, before the proclamation of the Turkish Republic. The process of unionization has had to confront two obstacles: on the one hand, the tendency of teachers’ associations and unions to be co‐opted by the ruling party and thus to lose their militancy; on the other hand, the fact that although professional associations may have been permitted to exist by certain Turkish regimes, true unionization, and above all, the right to strike, has been prohibited on the grounds that teachers are civil servants and like all civil servants do not have the right to strike. The latter restriction was most recently confirmed by provisions in the Constitution of 1982. Thus Turkey is the only country in Europe in which teachers do not have the right to form true labour unions and to go on strike.

内蒙古河套地区农业开发与环境变化的关系分析

河套地区是内蒙古自治区的商品粮基地,随着近代农业发展规模的不断扩大,以土地盐碱化、土地沙化为核心的生态环境恶化问题日趋突出,已严重制约了该地区农业的可持续发展。河套地区生态环境的变化是自然过程和人类社会长期发展影响共同作用的结果。该地区农业发展的历史,就是近现代生态环境演变的历史。开展农业开发与生态环境变化相关关系的研究,将为河套地区农业可持续发展提供科学的依据     

TELEVISION IN THE TEACHING OF CHEMISTRY: A REVIEW FROM FURTHER EDUCATION

The uses and potentialities of educational television as described by recent authors are reviewed, and television compared with film from the viewpoints of producer and audience, while off‐air recordings are compared with ‘home‐made’ programmes.

The author concludes with an extensive review of the literature concerned with the uses of television in the teaching of chemistry. While the review does not attempt to list every possible reference, none of the few that have been omitted adds substantially to the uses mentioned, and the survey should provide a basis for those interested in beginning research in this field, as well as those contemplating the introduction of television into chemistry teaching.

The article was prepared in connection with research into student attitudes to educational television, the results of which will appear in the next issue of the Journal.     

THEORY AND PRACTICE IN THE EDUCATION OF TEACHERS

This paper reports an investigation into the method described by Hertzig et al. (1968), for measuring the response style of pre‐school children performing cognitive tasks (the Stanford‐Binet Intelligence Test Form L). The inter‐observer reliability of the major variables proposed as parameters of ‘cognitive style’ is examined, as well as their stability over time, and their association with level of test performance.

It was not found possible to record behaviour in adequate detail using the original method of a handwritten protocol so a modified procedure was adopted in which observers classified responses directly by their type and recorded them in code. Using this method, reliability was found to be high. Moreover, over a period of four to six weeks there was substantial consistency in the style of behaviour shown by these children when dealing with test demands.

Since there were ethnic differences in the small sample of children studied (N=32), it was also of interest to discover whether children of immigrant and English‐born parents would show differences in behaviour comparable to the differences between Puerto Rican and middle‐class American children reported by Hertzig et al. Some behavioural differences were found, but these appeared to be wholly a function of differing test performance.

THE PLACE OF A SINGLE CAMERA VIDEO SYSTEM IN A CHEMISTRY DEPARTMENT

In recent years there has been an upsurge in the number of academic departments which possess their own video equipment. The Department of Chemistry at Queen Elizabeth College is one such example: it has its own VCR and camera. Details are given of the use to which this equipment is put, including the different types of programmes which are generated within the department and the production techniques employed therein. The educational benefits, advantages and disadvantages of video as a teaching and learning aid for both staff and students, are discussed.

Observations and experience indicate that frequently there is an underlying dissatisfaction with programmes produced by central ETV units and that this stems from the poor relationship which often exists between the academic and the producer. A re‐examination of this relationship is included, along with some suggestions as to how it might be improved.     

PROFILE OF NEW TEACHERS IN THE TURKISH EDUCATIONAL SYSTEM

A profile of students entering the teaching profession in Turkey was developed based on demographic and academic information obtained from the University Entrance Examination (UEEX) for 1982 and 1986. Findings reveal that low achieving students and others from low‐income families comprise the majority of persons desiring to become teachers at the elementary and secondary levels, thus posing the possibility of education serving as a vehicle for upward mobility. Alternative are considered so as to alleviate the consequences of the entering of less capable leaders into education than was the case in the past, in Atatürk's time, when educators were held in high esteem.
