Teachers’ belief that math requires innate ability predicts lower intrinsic motivation among low-achieving students

Many students find math difficult, but those who are intrinsically motivated learn and do well even when they face obstacles. Here, we examine an environmental factor that might affect students' intrinsic motivation in math: namely, teachers' beliefs about success in math. Do teachers perceive elementary school math as a domain that requires an innate ability, and does this belief relate to students' intrinsic motivation in math? Our study explored these questions in a sample of 830 German fourth graders and their 56 teachers. Teachers reported stronger beliefs in the role of innate ability for math than for German language arts. In addition, the more teachers believed that math requires innate ability, the lower was the intrinsic motivation of their low-achieving students. These results suggest that teachers’ beliefs that math success depends on innate ability may be an important obstacle to creating a classroom atmosphere that fosters engagement and learning for all students.     

Stability and change in US prospective teachers’ beliefs and decisions about diversity and learning to teach

Helping prospective teachers develop the beliefs, knowledge, skills, attitudes, and practices necessary to meet the needs of diverse learners in the US is critical given that the teaching force remains overwhelmingly White, monolingual, and middle class and the student population is increasingly diverse. Teacher education programmes, in particular, are faced with the arduous task of creating courses and other experiences for prospective teachers that help mitigate some of the challenges that diverse learners encounter in public schools. The results of a course that attempted to help prospective teachers gain a richer understanding of diversity is reported in this article. Particular attention is placed on the stability and change of the prospective teachers’ beliefs and practices around diversity and learning to teach as a result of the course. The results suggest that the extent of change in prospective teachers’ beliefs and practices was linked explicitly to their interactions and experiences with diverse individuals and contexts. The development of international immersion partnerships is suggested as a means to help US prospective teachers develop the consciousness, skills, and knowledge necessary to teach culturally and ethnically diverse students in ways that optimise teaching and learning.     

谈小学语文低段朗读指导的基础性

朗读指导是小学语文教学中重要环节。针对低年级学生的朗读实际,应重视进行基础性的朗读指导。教师在教学中要教给朗读技巧,使学生"会读";把握朗读环境,让学生"美读";优化评价语言,促学生"乐读"。从小学低年级起抓好扎实的朗读基础,才能逐步提高朗读水平。     

初中数学自主探究式教学的策略

培养学生的数学探究能力成为初中数学教学的焦点和主题。文章根据教育学、心理学研究学生学习数学的心理,通过实例探讨培养学生自主探究数学的途径在于:创设"想"的氛围,激发探究兴趣;创设"动"的氛围,加强实践操作;创设"问"的氛围,鼓励参与探索。同时,提供生活实例,让学生灵活运用数学;创设成功情景,让学生在数学中体验成就感。如此,方能让学生通过自己的动手操作,在积极参与教学活动的过程中去体验、亲近和应用数学,最终真正成为数学学习的主人。

Relations among parental causal attributions and children’s math performance and task persistence

The present longitudinal study examined the cross-lagged relations between parental causal attributions of children’s math success to children’s ability, parental help, children’s math performance and task persistence. A total of 735 children, their mothers, fathers and teachers were assessed twice – at the end of the second and the third grades. Children were tested in math and parents filled out questionnaires measuring causal attributions. Children’s task persistence was reported both by parents and by class teachers. The results of path analyses indicated mutual negative effects between mothers’ and fathers’ help attributions and children’s math performance, and a positive effect of mothers’ ability attributions on children’s math performance. Cross-lagged relations were also found for children’s math performance and task persistence. However, relations between parental attributions and children’s task persistence were evident only for fathers’ ability attributions. The findings emphasise the importance of examining both mothers and fathers, home and school context.

Why does teacher gender matter?

This paper shows that high school math and science teacher gender affects student interest and self-efficacy in STEM. However, such effects become insignificant once teacher behaviors and attitudes are taken into account, thus pointing towards an omitted variables bias. Teacher beliefs about male and female ability in math and science – as well as how teachers treat boys and girls in the classroom – matter more than teacher's own gender. The student fixed effects estimates also highlight that creating a positive learning environment and making math and science interesting are pivotal in engaging students in these subjects.     

Prospective Turkish primary teachers’ views about the use of computers in mathematics education

The use of computers and technology in mathematics education affects students’ learning, achievements, and affective dimensions. This study explores prospective Turkish primary mathematics teachers’ views about the use of computers in mathematics education. The sample comprised of 129 fourth-year prospective primary mathematics teachers from two different universities in Turkey. Data consisting of participants’ written responses were qualitatively analyzed and categorized according to TPACK. Results show that the prospective teachers’ views about computers and their use in mathematics are usually positive. They enjoy working with computers, even though they are only able to perform relatively minor calculations with computers. They stated that improved use of computers can help them to learn and teach mathematics more effectively. However, they did not feel confident about their ability to teach mathematics using computers.
