Eliciting Mathematics Interest: New Directions for Context Personalization and Example Choice

Building on common assumptions in theories of interest and mathematics education, this experimental study examined the effect of context personalization based on individual preferences, group personalization, and example choice with preselected popular examples on middle school students' situational interest and performance in mathematics. Participants (N = 713) learned a principle in probability calculus in one of four instructional conditions. Individual interest and perceived competence were examined as moderators on triggered and maintained situational interest, perceived value, task effort, and performance. Results showed that example choice triggered situational interest in the learning activity and that context personalization influenced perceived value and effort, contingent on students' perceived competence and individual interest in mathematics. We discuss results in relation to previous findings on interest-based interventions and the theoretical and practical implications.     

Two secondary teachers’ understanding and classroom practice of dialogic teaching: a case study

Dialogic Teaching (DT) is effective in fostering student learning; yet, it is hard to implement. Little research focused on secondary teachers’ learning of DT and on the link between teachers’ understanding and practices, although these two are usually strongly intertwined. Using a wide range of evidence, this case study systematically investigated and compared two secondary teachers’ understanding and practice of DT during their participation in a continuing professional development programme (CPDP). The CPDP appeared effective to some extent. The History teacher’s understanding of DT, i.e. being a co-learner, appeared highly effective in implementing DT, whereas the Mathematics teacher’s understanding of DT, i.e. creating a democratic learning environment, seemed only effective to some extent. Focusing on both teachers’ understanding and practice when developing DT seemed fruitful in explaining differences in practice. Future research could further explore to what extent understanding DT as being a co-learner facilitates professional development.     

What supports 11- to 13-year-old Pasifika students in mathematics learning in New Zealand classrooms?

The steepest decline in achievement in New Zealand primary schools occurs in Years 7 and 8, with the greatest decline in the subject area of mathematics. The cohort that achieves at the lowest level in New Zealand schools is Pasifika. This study considers the views of those stakeholders involved in the teaching of these children. It seeks to uncover the positive steps being taken to advantage this group and the difficulties principals, teachers and parents face to improve achievement. One-to-one interviews were used to elicit advice and information to provide evidence of best teaching practices for Pasifika students     

Does class-size reduction close the achievement gap? Evidence from TIMSS 2011

Policies about reducing class size have been implemented in the US and Europe in the past decades. Only a few studies have discussed the effects of class size at different levels of student achievement, and their findings have been mixed. We employ quantile regression analysis, coupled with instrumental variables, to examine the causal effects of class size on 4th-grade mathematics achievement at various quantiles. We use data from 14 European countries from the 2011 sample of the Trends in International Mathematics and Science Study (TIMSS). Overall, there are no systematic patterns of class-size effects across quantiles. Class-size effects are generally non-significant and uniform at different achievement levels, which suggests that in most European countries class-size reduction does not have an impact on student achievement and does not close the achievement gap. However, combined estimates across countries indicate that high achievers may benefit more from class-size reduction.     

The postmodern perfectionist,the pragmatic hedonist and the materialist maximalist: understanding high school students’ profile choices towards or away from mathematics,science and technology (MST) fields in the Netherlands

This study focuses on high school students’ profile choices and the choice for or against the Nature and Technology (NT) profile in the Netherlands. A mixed-methods approach is used to study cultural values that affect this choice. The quantitative part of the study shows that being female is negatively correlated with the choice for the NT-profile, irrespective of the grade average for mathematics, chemistry and physics. It further shows that students’ ethnic background does not have a significant effect on this choice. The qualitative part of the study reveals that students’ choice processes towards or away from NT can be categorised in three ideal types: the postmodern perfectionist, the pragmatic hedonist and the materialist maximalist. Gender differences appear to be more pervasive across these types than differences in ethnic background.     

Introduction to the Special Issue on Perspectivesand Experiences on Mentoring Undergraduate Students in Research: Part II

Abstract

This issue is the second of a special PRIMUS two-part issue collecting articles on undergraduate research from experienced faculty mentors. We offer it as a valuable resource for faculty leading undergraduate research programs. This issue presents a collection of papers offering advice on a variety of specific topics important for leaders of undergraduate research programs. Issues of finding and designing appropriate and accessible research projects, assessing undergraduate research, and publicizing it in the media are addressed.
