Organismic integration as a dynamic process: a systematic review of empirical studies on change in behavioral regulations in exercise in adults

In facilitating the adoption of exercise behavior, attention should be directed towards the dynamic nature of behavioral regulations. Organismic integration theory presents a suitable framework for investigating fluctuations in behavioral regulations. However, current results pertaining to this issue revealed mixed findings. The aim of this review is to examine the empirical literature on the dynamic nature of organismic integration theory in exercise settings over time in adults. A systematic review of English articles using PsycINFO, PsycARTICLES, ScienceDirect, and SPORTDiscus was conducted including keywords of organismic integration theory, longitudinal designs, change in behavioral regulations, and exercise. Findings are summarized through quantitative analysis of the evidence. Regarding autonomous regulations, steady increases in regulations are observable that originate within the first weeks and persist for up to one year. Most studies reported no changes in controlled regulations, although in a few cases changes were observed six weeks after baseline or later. The review adds to the theoretical understanding of how behavioral regulations are internalized. However, whether changes in regulation occur depends on both the type of regulation and on contextual characteristics. Future research of longitudinal design is warranted to identify optimal periods in which individuals seek for increased support during exercise adoption.

The influence of discussion groups in a case-based learning environment

The common practice of using discussion groups during case-based learning makes the role of discussion important in these learning environments. However, little empirical research has been done to investigate the influence of discussion on performance and motivation in case-based learning. The purpose of this article is to present the results of a study conducted to examine the role of discussion groups in a case-based environment. College students completed two cases either individually or in small discussion groups. Measures included two case analyses, an attitude survey, time on task, and document analysis. Results revealed significant performance and time differences between instructional methods on the first case, but not on the second case. In addition, results indicated significant differences in student attitudes between treatments. Overall, participants who worked in groups liked their method significantly better than those who worked alone, felt they learned more working in a group than they would have working alone, and expressed a preference for working in a group if they had to do the class over again. Implications for implementing case-based learning and future research are discussed. Anna E.

心理授权理论对课堂英语教学的启示

作为管理学领域中的概念,心理授权在教学中的应用还相对较少,而心理授权研究本身还缺乏对具体实施方法的相关研究。为了将心理授权这一理念引入课堂英语教学并促进心理授权具体实施方法的探索,文章通过对心理授权理论的回顾和分析,联系课堂英语教学,试图建立二者的联系来提高课堂英语教学的效率和对学习者的关注程度。结论:心理授权的适用环境和适用对象在很大程度上与课堂英语教学的环境和对象类似;通过对心理授权模型中各因素的分析,文章提出应将心理授权的理论应用于英语课堂,并总结了对课堂英语教学的相关启发。     

Evaluation of the non‐formal forest education sector in the state of North Rhine‐Westphalia,Germany: organisations,programmes and framework conditions

Although a large number of different organisations offer various forest education programmes within Germany, specific information (i.e., sectoral and programme content and provision at a state level) is lacking. This study used a survey of all 61 forest education organisations (43 respondents) in the state of North Rhine‐Westphalia, Germany, to evaluate its forest education sector, with a specific focus on the organisations, demand for its services, forest educational programmes and framework conditions. Input from expert interviews was also used to develop recommendations. The study indicates that, especially with children as the main target group, many non‐formal programmes are offered to support the formal environmental education sector and to promote leisure activities in the forest. Yet, despite a high demand for forest education, low personnel resources restrict the number of visits and activities, principally owing to limited financial resource. We also discuss the provision of innovative new educational programmes and supplementary services, combined with increased quality management, that could be beneficial to the future development of the sector in NRW.
