Classroom silence is complex and discrete problem.It affects the overall teaching and learning quality as well as the high-quality development of both teachers and students.Avoiding classroom silence is a highly dynamic and valuable learning process.This study explores the ecological logic of classroom silence of both teachers and students based on the connotation of classroom silence and deconstructs the endogenous and exogenous mechanisms of classroom silence from the perspectives of escape culture and the continuity theory.Following that,we construct a new model of interaction for elementary school classroom,which includes optimizing the teaching evaluation tools,creating a multidimensional physical technology environment,and fostering an interactive culture of returning to the classroom,so as to promote the overall classroom effectiveness. 展开更多

During space missions,astronauts live in a confined technological environment,completely isolated and deprived of the variety and variation found in the environment on Earth.This circumstance has a strong impact on the psycho-physiological states of the crew.Particularly in light of the plans for long-duration missions,new research needs to be carried out.The goal of this study,conducted at Xiangtan Central Hospital in China,was to test whether multicolour lighting can improve people’s psychological state in an isolated and confined environment over a period of seven days.Twenty participants(10 male and 10 female)were randomly divided into two groups:one group that was exposed to multicolour lighting and a control group,which was exposed to a static,monotonous white interior.The participants’psychological state was recorded on the first day,the fourth day,and the seventh day.The results of the control group showed that the participants’negative emotions and anxiety continued to increase over time,whereas the group randomly exposed to multicolour lighting that changed every three hours did not show any significant increase in negative emotions and anxiety.Moreover,the random change of light colour in the isolated environment appeared to help the participants increase their sense of surprise,thereby counteracting monotony.Finally,during this experiment,it was observed that when people who are accustomed to being connected to social networks were deprived of this,they experienced insomnia and unaccustomed reactions,in particular on the first days of deprivation.This article contributes to future space exploration and to social and psychological support of life in isolated and confined environments. 展开更多
