Additive and multiplicative effects of working memory and test anxiety on mathematics performance in grade 3 students

The aim of this study was to investigate the interplay between test anxiety and working memory (WM) on mathematics performance in younger children. A sample of 624 grade 3 students completed a test battery consisting of a test anxiety scale, WM tasks and the Swedish national examination in mathematics for grade 3. The main effects of test anxiety and WM, and the two-way interaction between test anxiety and WM on mathematics performance, were modelled with structural equation modelling techniques. Additionally, the effects were also tested separately on tasks with high WM demands (mathematical problem-solving) versus low WM demands (basic arithmetic). As expected, WM positively predicted mathematics performance in all three models (overall mathematics performance, problem-solving tasks, and basic arithmetic). Test anxiety had a negative effect on problem-solving on the whole sample level but concerning basic arithmetic only students with lower WM were affected by the negative effects of test anxiety on performance. Thus, students with low WM are more vulnerable to the negative effects of test anxiety in low WM tasks like basic arithmetic. The results are discussed in relation to the early identification of test anxiety.     

An examination of male-female performance in a programmed achievement learning center

College students operated under different classroom contingencies. The Programmed Achievement (PA) condition required students to evidence criterion performance (100% mastery) on weekly quizzes. Failure to show mastery performance on any of the weekly quizzes resulted in course failure. The Standard Control (S-C) condition involved a more traditional college classroom structure where students took weekly quizzes with no requirement to evidence mastery. Male and female performances were analyzed to determine if different course structures interacted with sex of student. The results indicated that PA students demonstrated higher performance than controls on weekly quizzes and a major exam. It was also shown that PA females increased at a more rapid rate than PA males, while S-C males and females were not significantly different. Theoretical implications of the results are discussed.     

关于Diophantine方程x3-p3n=Dy2

设P是奇素数，D是无平方因子正奇数，本文证明了：当p≡5(mod12)，D≡1(mod4)时，如果D不能被P或6k 1之形素数整除，则方程x^3-P^3n=Dy^2没有适合gcd(x，y)=1的正整数解(x，y，n)．     

Inquiry-Based Science and Technology Enrichment Program for Middle School-Aged Female Students

This study investigates the effects of an intensive 1-week Inquiry-Based Science and Technology Enrichment Program (InSTEP) designed for middle school-aged female students. InSTEP uses a guided/open inquiry approach that is deepened and redefined as eight sciences and engineering practices in the Next Generation Science Standards, which aimed at increasing female students’ interest in science and science-related careers. This study examined the effectiveness of InSTEP on 123 female students’ pre-assessment and post-assessment changes in attitudes toward science and content knowledge of selected science concepts. An attitude survey, a science content test with multiple-choice questions, written assignments, and interviews to collect data were all used to measure students’ attitudes and content knowledge. A within-group, repeated measure design was conducted, and the results indicated that at the post-intervention level, InSTEP increased the participants’ positive attitudes toward science, science-related careers, and content knowledge of selected science concepts.

原象——中国审美意象的历史生成

意象是中国文艺美学中一个非常重要的范畴,包含着丰富深邃的哲学美学思想。意象概念并非凭空生成,而具有哲学文学两方面的长期积累。从先秦有关“言”、“意”、“象”关系的论述,到魏晋玄学兴起,深化对“言”、“意”、“象”三者的思辩,加上先秦《诗》、《骚》以及两汉魏晋文学创作对文论的影响,才最终形成这一独具东方民族色彩的范畴。
