In line with previous studies, where outdoor nature experience was shown to support adolescents’ environmental knowledge, our study monitored the influence of a hands-on environmental programme within a National Park on cognitive knowledge achievement. A sample of 4th and 5th graders (n = 289) completed a week-long outreach conservation programme with two follow-up options: the first group (n = 170) interacted with thematic posters, the second group (n = 128) also completed a thematic board game. In a quasi-experimental design, we analysed both versions with regard to achievement efforts and individual situational emotions. Altogether, programme participation added cognitive knowledge, while group one (poster and board game as follow-up option) outmatched group two (just the poster option). Measures of 'state' and 'situational' emotions regarding the programme and right after game participation revealed positive effects toward knowledge. Thus, we conclude, direct experiences with nature and additional hands-on follow-up activities may foster a student’s cognitive achievement in such programmes. 相似文献

Since Sinclair and Coulthard introduced the follow-up move in 1975,it has attracted a great deal of attention.However,most of the studies focus on English while Chinese has been neglected.This article aims to analyze Chinese conversational structure and investigate the role of the follow-up move.The present study is based on twenty natural Chinese conversations and Tsui’s(1994) conversational framework.As the result will show,the presence or absence of the follow-up move in Chinese conversations relies heavily on the interlocutors’gender. 相似文献

This study examines teaching evaluation based on student feedback which is intended to contribute to teachers’ professional development. Although studies have highlighted that teaching evaluation is a potential source of professional development and that follow-up sessions are crucial to this benefit, little attention has been paid to the usefulness of follow-up sessions as perceived by the teachers involved. Based on 217 teacher responses and analysis done with Structural Equation Modelling, this article provides additional insight into teaching evaluation by investigating possible antecedents for teachers’ perceived usefulness of follow-up sessions and for evaluation-related stress. Our results indicate that the perceived developmental purposes of teaching evaluation, recognition of the person conducting follow-up sessions and perceived clear communication from leaders are positively related to teachers’ perceived usefulness of follow-up sessions. Higher levels of perceived control purposes are related to higher levels of reported stress among the evaluated teachers. 相似文献
