This study applied situated learning appoach in the interpretation course of college English major students and is designed to gain the students' perception of stuated learning. From the study, it is found that most of the students showed their positive attitudes towards situated learning approach applied in their interpretation course and enjoyed their learning in such learning enviroment. However, there is still a long way to go to achieve their satisfaction. Teachers need to explore more for creating authentic atmosphere in the interpretation course to arise students' interest and passion to a greater degree.展开更多

With large sample data and high-resolution remote sensing images, we explored the spatial differentiation and influencing factors of household embedded carbon emissions within the city fine scale using the EIO-LCA model, spatial autocorrelation analysis and standard deviation ellipse, quantile regression, etc. The results indicate that the spatial dependence is more obvious than the characteristics of spatial heterogeneity;the high-value area of household embedded carbon emissions gathers in new development zones in cities that are expanding rapidly, mainly with residents in large number of newly-built commercial housing families and the relative’s courtyard of institutions. The factors of family characteristics, housing characteristics, lifestyles, and consumption concept have significant effects on the embedded carbon emissions of each person. The influencing intensity of most factors showed an increasing trend with increased carbon emissions. The study verified the impact of urban sprawl on residential carbon emissions and the applicability of the situated lifestyles theory in the construction of urban low-carbon communities in China.展开更多

Current research suggests, however, that as students persist in this activity their situational interest decreases as their ability to exercise consistently at moderate intensity levels increases. In this article I will briefly review the literature citing benefits of exergaming and the role of exergaming in contemporary PE curricula before turning to the question of the place of exergaming in a learning- oriented approach to PE. I will suggest that exergaming, when taught within a situated learning framework, can contribute to student under- standing of the effects of exercise on their bodies and may produce meaningful lessons to assist students to create, monitor, and adapt a fitness plan to participate in life long exercise using a variety of physical activities.

Previous studies observedassociations between features of emerging adulthood and PA levels, while the potential psychological mechanisms that mightexplain this phenomenon are not fully understood. In this context, there is some evidence that situated decisions towardphysical activity (SDPA) and exercise-intensity tolerance might influence PA level. To provide empirical support for thisassumption, the current study investigated whether (i) features of emerging adulthood are linked to SDPA, which, in turn,might affect PA engagement;(ii) exercise-intensity tolerance moderate the relationship between SDPA and PA level;and (iii)SDPA is a mediator of the relationship between features of emerging adulthood and PA levels under the prerequisite thatexercise-intensity tolerance moderates the link between SDPA and PA engagement. In this study a group of 1,706 Chinesecollege students was recruited and asked to complete a set of questionnaires assessing their SDPA, PA levels, exercise-intensitytolerance, and features associated with emerging adulthood, namely Self-exploration, Instability, and Possibility. Our resultsindicated that SDPA positively predicted PA levels and this relationship became stronger when exercise-intensity tolerance wasused as a moderator. Furthermore, it was observed that individuals with a higher level of Instability and a lower level ofPossibility during emerging adulthood exhibited a lower level of SDPA. Taken together, the results of our study providefurther insights on a potential psychological mechanism linking features of emerging adulthood and physical activity.展开更多
