Making the Hidden Explicit: Learning About Equity in K-8 Preservice Science Education

Preservice teachers in a K–8 science methods course used guided video reflection to examine their interactions with children during science teaching. This inquiry approach helped preservice teachers identify and respond to gaps between their beliefs and intentions about teaching all children and their enactment of those beliefs. The experience of teaching a science lesson and then viewing it multiple times through a critical framework provided an opportunity for preservice teachers to recognize hidden assumptions, unexamined behaviors, and the unintentional meanings they may have conveyed to children. This encouraged them to think more critically about their roles as teachers in creating spaces where all children have access to quality science learning experiences.

The quadratic relationship between socioeconomic status and learning performance in China by multilevel analysis: Implications for policies to foster education equity

The purpose of the present study is to explore the relationship between family socioeconomic status and mathematics performance on the base of a multi-level analysis involving a large sample of Chinese primary school students. A weak relationship is found between socioeconomic status and performance in the Chinese context. The relationship does not follow a linear, but a quadratic curve, implying that students from a disadvantaged family and higher socioeconomic background have a higher probability to attain higher mathematics scores. This can be explained on the basis of Chinese cultural beliefs about education, exams and social class mobility. Moreover, the aggregated socioeconomic status at the school level seems to moderate in the relation between individual SES and academic performance. This suggests that individuals from a disadvantaged family will achieve higher in the school with a higher family socioeconomic status than students who are enrolled in schools with a lower and average family socioeconomic status.

Orientations of prospective teachers toward students' family and community

Teacher educators need an awareness of orientations that prospective teachers (PSTs) hold about children's families and communities, so that they can support PSTs in developing positive perspectives and addressing deficit perspectives. Orientations expressed by 20 PSTs while in preK-8 mathematics methods courses are examined. Results from interviews indicate that PSTs recognize the importance of connecting with parents, understanding home and community practices, and building on these practices to support children's mathematical learning. They also, however, exhibit inconsistent perspectives, at times indicating a lack of understanding as to why some families appear to be less able to support students' academic efforts.
