Incremental validity of thinking styles in predicting academic achievements: an experimental study in hypermedia learning environments

The study examined the incremental validity of thinking styles in predicting academic achievement after controlling for personality and achievement motivation in the hypermedia‐based learning environment. Seventy‐two Chinese college students from Shanghai, the People’s Republic of China, took part in this instructional experiment. The End‐Of‐Semester test was designed to examine the students’ achievement in the course of General Psychology. The results partially supported the hypotheses concerning the relationships between students’ Type I and II thinking styles and their academic achievement in Type I test (including analysis, problem‐solving, and essay tests) and Type II test (including multiple‐choice and cloze tests), and showed that some Type III styles were significantly related to their academic achievement. Hierarchical regression analysis indicated that the capacity of thinking styles for explaining and predicting academic achievement was sometimes over and above the sum of personality traits and achievement motivation. Implications for educational practice are discussed.

Judgment‐Based Scoring by Teachers as Professional Development: Distinguishing Promises from Proof

The engagement of teachers as raters to score constructed response items on assessments of student learning is widely claimed to be a valuable vehicle for professional development. This paper examines the evidence behind those claims from several sources, including research and reports over the past two decades, information from a dozen state educational agencies regarding past and ongoing involvement of teachers in scoring‐related activities as of 2001, and interviews with educators who served a decade or more ago for one state's innovative performance assessment program. That evidence reveals that the impact of scoring experience on teachers is more provisional and nuanced than has been suggested. The author identifies possible issues and implications associated with attempts to distill meaningful skills and knowledge from hand‐scoring training and practice, along with other forms of teacher involvement in assessment development and implementation. The paper concludes with a series of research questions that—based on current and proposed practice for the coming decade—seem to the author to require the most immediate attention.     

Evaluating the Comparability of Paper‐ and Computer‐Based Science Tests Across Sex and SES Subgroups

As access and reliance on technology continue to increase, so does the use of computerized testing for admissions, licensure/certification, and accountability exams. Nonetheless, full computer‐based test (CBT) implementation can be difficult due to limited resources. As a result, some testing programs offer both CBT and paper‐based test (PBT) administration formats. In such situations, evidence that scores obtained from different formats are comparable must be gathered. In this study, we illustrate how contemporary statistical methods can be used to provide evidence regarding the comparability of CBT and PBT scores at the total test score and item levels. Specifically, we looked at the invariance of test structure and item functioning across test administration mode across subgroups of students defined by SES and sex. Multiple replications of both confirmatory factor analysis and Rasch differential item functioning analyses were used to assess invariance at the factorial and item levels. Results revealed a unidimensional construct with moderate statistical support for strong factorial‐level invariance across SES subgroups, and moderate support of invariance across sex. Issues involved in applying these analyses to future evaluations of the comparability of scores from different versions of a test are discussed.     

提升师德因生施爱

作为一名教师应学会比较,善于比较,通过机遇和更差的比,干劲和更足的比,道德和高尚的比,目标和接近的比,将来和更强的比,需要和入党时比,不断反思,不断成长,努力提升师德修养,成为自己心目中的好老师,学生、家长、同事心目中的好老师和人民满意“德艺双馨”的好老师。实施新课改的核心理念是以人为本,关注每一位学生,为了每一位学生的发展。对教师来说就是要以人为本,因生施爱,做到尊重并“偏爱”后进生;鼓励并“博爱”中等生;赏识并“严爱”优秀生。     

《鬼妈妈》恐怖元素与作用探析

随着制作观念的开放,新的青少年儿童文艺形式不断衍生,融入了恐怖元素的作品大量涌现,影片《鬼妈妈》就是一部成功之作。儿童片与恐怖因素并非势不两立,合理适度的运用恐怖因素有利于激发青少年儿童的想象力,培养他们分辨是非的能力和勇于挑战的精神。少儿文艺影视作品的恐怖元素也会对青少年儿童带来不良影响,在其应用于儿童片时应以禁止滥用、避免危害少年儿童为原则。     

以制度创新推动西部地区的生态环境建设

西部大开发对我国21世纪的发展意义重大，西部大开发要把生态环境建设放在突出的位置，走可持续发展之路，目前，我国的相关体制与制度尚不适应西部地区生态环境建设的要求，当务之急是推进制度创新，构建和完善西部地区生态环境建设的激励和约束机制，为西部地区的生态环境建设创造良好的制度性保障。     

Evidence‐Based Teaching in Higher Education: Application to Counselor Education

The authors examined best practices in university‐level teaching, as premised on the evidence‐based teaching (EBT) literature found in fields external to counselor education. Findings were reported in relation to 3 areas: developing an effective learning environment, structuring intentional learning experiences, and assessing teaching effectiveness. Implications regarding the training of doctoral‐level counselor educators using EBT practices are discussed.
