基于不同学习风格的英语教学设计

认知心理分析研究表明:在二语习得中,学习者个人的学习风格在一定程度上影响着学习效果。因此,教师在进行课堂教学设计时,要针对不同学习风格的学生采用相应的教学策略。同时,认知因素和非认知因素也极大地影响着学生的语言习得,教师应该充分利用学生认知因素和非认知因素来进行英语教学设计。     

抗强电磁干扰可直接启停电机逆变电源的研制

由于中频无源电焊机机内发电机不能发出50Hz的工频交流电,所以在野外施工中不能利用焊机内的发电机给现场的检测仪器和泥浆泵等设备供电.如果给中频无源焊机配备50Hz工频逆变电源,将会使该设备具有更高的使用性和性能价格比.本文研制了中频无源焊机内置2KW工频逆变电源,并且很好的解决了抗干扰问题,提高了工频逆变电源工作的稳定性.     

Assessing twenty‐first century skills through a teacher created video game for high school biology students

As twenty‐first century skills become a greater focus in K‐12 education, an infusion of technology that meets the needs of today’s students is paramount. This study looks at the design and creation of a Multiplayer Educational Gaming Application (MEGA) for high school biology students. The quasi‐experimental, qualitative design assessed the twenty‐first century skills of digital age literacy, inventive thinking, high productivity, and effective communication techniques of the students exposed to a MEGA. Three factors, as they pertained to these skills, emerged from classroom observations. Interaction with the teacher, discussion with peers, and engagement/time‐on‐task while playing the MEGA suggested that students playing an educational video game exhibited all of the projected twenty‐first century skills while being engrossed in the embedded science content.

Episodic and individual effects of elementary students' optimal experience: An HLM study

The authors defined optimal experience as a functional state of a relatively high level of concentration, time distortion, satisfaction, and enjoyment (Csikszentmihalyi, 1992 Csikszentmihalyi, M. (1992). The flow experience and its significance for human psychology. In M. C. I. S. Csikszentmihalyi (Ed.), Optimal experience: Psychological studies of flow in consciousness. London, England: Cambridge University Press. [Google Scholar]) and collected data through the Day Reconstruction Method. In three random days, 147 fifth-grade students answered questionnaires for each school event in the previous day resulting repeated data from 2,288 episodes. Several hierarchical linear models were conducted. The authors found that elementary students perceived better quality of optimal experience during break time versus classes taught by activity, seatwork or lecture methods. Unexpectedly, more optimal experience was reported in the events when students perceived themselves as having high skill but low challenge, contradictory to the original expectation of skill–challenge balance. Four additional flow conditions were more effective than primary flow condition and instructional methods in predicting optimal experience. Finally, optimal experience varied much more across event-episodes than among individuals meaning that teachers have rooms to improve students' optimal experience in elementary school days.     

转型时期权力失控的制约措施
