远程教育学习支持服务满意度调查分析

远程教育机构关注的焦点在于学生的学。本研究把学习者的满意度作为学习支持服务的衡量标尺,从服务对象出发,展开学习支持服务满意度调查。结果表明,学习者对学习支持服务总体上呈现出比较满意的状态。专业对学生满意度影响较为显著;就地域来看,苏北、苏南区域差异变得不甚明显。研究者认为,必须根据学习者的需求,针对学习支持服务中存在的问题,更新理念,投入更多的人力与物力,为建设开放大学打下坚实基础。

用改进的元胞自动化模型模拟不同信号灯控制策略下的交通流

Traffic flows controlled by traffic light strategies were investigated via a cellular automaton model with anticipation, which is suitable for describing urban traffic. Three kinds of strategies, i. e., synchronized, green-wave and random switching lights, were designed, simulated and compared with each other. It is shown that the green-wave strategy is only valid at lower density and there is not an effective way with the three strategies to improve the efficiency of traffic flow at high density.

Personalized learning in iSTART: Past modifications and future design

Abstract

Computer-based learning environments (CBLEs) provide unprecedented opportunities for personalized learning at scale. One such system, iSTART (Interactive Strategy Training for Active Reading and Thinking) is an adaptive, game-based tutoring system for reading comprehension. This paper describes how efforts to increase personalized learning have improved the system. It also provides results of a recent implementation of an adaptive logic that increases or decreases text difficulty based on students’ performance rather than presenting texts randomly. High school students who received adaptive text selection showed increased sense of learning. Adaptive text selection also resulted in greater pre-training to post-training comprehension test gains, especially for less-skilled readers. The findings demonstrate that system-driven, just-in-time support consistent with the goals of personalized learning benefit the efficacy of computer-based learning environments.
