Can Suggestions by Teachers Improve Instruction?

Twenty-four experienced teachers each selected a different reading skill and each prepared a set of written suggestions for teaching the skill selected. Subsequently, 24 unsuccessful teachers, i.e., those less able than their peers to effect pupil achievement in the skills, were identified. These unsuccessful teachers were randomly assigned to two treatment groups. One group received the previously prepared suggestions and the other group did not. Later, the two groups of teachers again taught the skills. It was found that all teachers receiving suggestions improved relative to their previous performance, i.e., their pupils achieved more, while only slightly more than half of those without suggestions showed improvement (p < .05). Thus, it was concluded that suggestions for teaching can be helpful to less successful teachers.

Does Reflective Journal Writing Improve Course Performance?

Abstract. This study investigated whether a reflective journal writing assignment would improve students' course performance. A total of 166 students from undergraduate sections of a course taught by the same instructor over three semesters completed the assignment as part of their requirements. Students (N = 317) from five previous semesters of the same course taught by the same instructor, who were not required to complete the assignment, served as a comparison group. Intervention and comparison groups were comparable on a variety of variables including all assignments, excepting the journal assignment. The findings are interpreted within the context of factors such as students' study habits and motivation.     

HPS and school science education: remediation or reconstruction?

Concern to incorporate historical and philosophical insights within school science curricula is an international phenomenon. Whatever the intrinsic merits of these insights, it is suggested that any willingness on the part of science educators to enter into a rapprochement with scholars in the history, philosophy and sociology (HPS) of science stems mainly from the perceived shortcomings of contemporary school science curricula. Some of the difficulties of incorporating HPS within school science are reviewed and it is argued that, together with broader questions about the role of science in society, historical, philosophical and sociological insights point towards a radical reappraisal of school science education. The article suggests three ways in which such education might respond to some recent work in the history, philosophy and sociology of science.

Does Higher Education Improve Student Scientific Reasoning Skills?

An ultimate goal of higher education is to prepare our future workers with needed knowledge and skills. This includes cultivating students to become proficient reasoners who can utilize proper scientific reasoning to devise causal inferences from observations. Conventionally, students with more years of higher education are expected to have a greater level of scientific reasoning. Also expected traditionally is that studying science and engineering or attending top-rated universities can better promote students’ scientific reasoning than studying other majors or attending lower ranked institutions. In this study, we used Lawson’s Classroom Test of Scientific Reasoning (LCTSR) with 1,637 Chinese students in different years of study, different fields, and different university tiers. It was found that regardless of which major or university students entered, their scientific reasoning measured by the LCTSR showed little variation across the entire 4 years of undergraduate education. Simply put, there was little association between tertiary-level learning and scientific reasoning. This study calls our attention to the status quo of higher education and motivates researchers across the globe to look into this issue in their own nations.

Does Children's Academic Achievement Improve when Single Mothers Marry?

Promoting marriage, especially among low-income single mothers with children, is increasingly viewed as a promising public policy strategy for improving developmental outcomes for disadvantaged children. Previous research suggests, however, that children's academic achievement either does not improve or declines when single mothers marry. In this paper, we argue that previous research may understate the benefits of mothers' marriages to children from single-parent families because (1) the short-term and long-term developmental consequences of marriage are not adequately distinguished and (2) child and family contexts in which marriage is likely to confer developmental advantages are not differentiated from those that do not. Using multiple waves of data from the ECLS-K, we find that single mothers' marriages are associated with modest but statistically significant improvements in their children's academic achievement trajectories. However, only children from more advantaged single-parent families benefit from their mothers' marriage.     

Does Investing in School Capital Infrastructure Improve Student Achievement?

Within the research community, there is a vigorous debate over whether additional educational expenditures will lead to improved performance of schools. Some of the debate is an outgrowth of the lack of causal knowledge of the impacts of expenditures on student outcomes. To help fill this void, we examine the causal impact of capital expenditures on school district proficiency rates in Michigan. For the analysis, we employ a regression discontinuity design where we use the outcomes of bond elections as the forcing variable. Our results provide some evidence that capital expenditures can have positive effects on student proficiency levels.
