Reducing the prior-knowledge achievement gap by using technology-assisted guided learning in an undergraduate chemistry course

There have been many practical obstacles for teachers to implement evidence-based educational technology, especially in STEM classrooms. By implementing learning principles related to Cognitive Load Theory, we developed an innovative Technology-Assisted Guided Learning (TAGL) approach and its web-based instructional tool, combining expertise from educational research and best teaching practices to enhance guided student-centered learning in chemistry. A total of 185 community college students were randomly assigned to learn stoichiometry through either TAGL or one of two active control interventions, traditional direct instruction and Khan Academy, a widely used web learning platform. We found that the TAGL group significantly outperformed both active control groups immediately after instruction, and furthermore, despite the fact that all groups received additional instruction in stoichiometry, the beneficial effects of TAGL compared to the control groups were maintained a month later. Notably, TAGL was able to eliminate the achievement gap between students with low prior knowledge and students with high prior knowledge. Furthermore, prior-knowledge activation was found to be especially beneficial for students with low prior knowledge. Our work contributes to existing research in learning theories and provides new insight toward the development of more effective and adaptive instructional designs. By translating research into practice, this study demonstrates the great potential of using innovative computer-based technology to improve student learning for all.

外包钢-混凝土连续组合梁的负弯矩极限承载力(英文)

对2根外包钢-混凝土连续梁试件进行了静力加载实验研究与承栽力分析.测量并分析了试件的荷栽-挠度及荷载-应变关系曲线.结果表明:外包钢-混凝土组合梁负弯矩区钢筋和外包钢梁通过抗剪连接措施能有效地共同工作,整体工作性能良好.在承栽能力极限状态,负弯矩和正弯矩最大截面的塑性应变均充分发展,并形成比较理想的塑性铰.随着配筋率的提高,组合梁受弯承栽力明显提高,而延性和转动能力相应降低.在试验数据基础上,给出了外包钢-混凝土组合梁在负弯矩区极限受弯承载力的计算公式,计算结果与实验结果吻合良好.     

论专业发展取向的小学教师在职教育的实施

在职教育在教师入职以后的教育教学质量提升中发挥着重要的作用,以教师个人的专业发展作为基本价值取向的小学教师在职教育的实施过程中,应该注意：更新观念,树立在职教育促进教师专业发展的意识;增加在职教育办学主体的多样性和开放性,充分尊重受训教师的自主性;根据不同的需求,对不同发展阶段的教师实行分层设课;提高培训者的素质水平,吸收小学专家型教师充实培训者人才库;建立合理的评价体系,促进小学教师在职教育的科学化、规范化。     

Beyond gender identity?

This paper focuses on the continuing significance of gender identity as a category of analysis within the field of gender theory and research in education. I begin by considering contemporary discussions of the limitations of research relating to gender theory and research in education. Following on from this, I explore some contemporary theorising on the category of gender within educational research in order to highlight ongoing debates that I perceive in the field. Finally, via a discussion of school toilets and gender performance, I consider how theoretical discourses relating to space and architecture might further develop the utility of gender as a category of analysis within education.     

Students' comprehension of science textbooks using a question‐based reading strategy

Despite the heavy reliance on textbooks in college courses, research indicates that college students enrolled in first‐year science courses are not proficient at comprehending informational text. The present study investigated a reading comprehension questioning strategy with origins in clinical research based in elaboration interrogation theory, which outlines how to encourage readers to recall relevant background knowledge while reading text materials. The theory suggests that the strategy increases the likelihood that readers will integrate what they read with what they know to make new knowledge. The setting for the study more closely resembled classroom conditions compared to similar studies in the past. Unlike previous studies on reading comprehension, students read a challenging passage from the textbook used in a science course in which they were enrolled. In addition, the text was longer than that used in clinical research. The college students (n = 294) in this study were randomly assigned to either a questioning strategy treatment or a rereading placebo‐control. While reading, treatment students were presented with statements taken from regular intervals in their textbook (about every 150 words) and asked a simple why question about each of these statements. Significant differences were found favoring elaborative interrogation theory and its question strategy treatment over the placebo‐control in terms of science comprehension even after significant estimated predictors of prior knowledge and verbal ability were statistically controlled or accounted for by removing the statistical contributions of these predictors to the main effects. © 2010 Wiley Periodicals, Inc.
