We interrogate the opportunities and challenges of using mixed methods (MM) within a developmental evaluation (DE) context by drawing on two illustrative cases that investigated educational change in Canada. Methods: Multi-case design and cross-case analysis, with a focus on examining common patterns across the two cases, enabling new ways of…

The Math for All (MFA) qualitative research team approached the randomized control trial (RCT) mixed methods investigation from a "pragmatic" perspective (Cresswell and Plano-Clark, 2011), that is, the belief that multiple realities can exist and that neither a qualitative nor quantitative approach is valued over the other. Further, the…

The following research report documents a professional development that focused on promoting understanding of algebraic learning progressions across vertical teams of elementary and secondary teachers. Analyzing quantitative data from the pre and post MKT assessment and qualitative data from lesson reflections and final course reflections,…

Detailing is a linguistic tool for mathematical argumentation in which given mathematical information is operationalized through one's warrants to support a claim. Recent literature suggests that students' detailing is related to their early algebraization. This study examined 168 elementary students' use of detailing in two mathematical…

This research report presents the final year results of a three-year research project on computational thinking (CT). The project, funded by the National Science Foundation, involved training teachers in grades four through six to implement Scalable Game Design and LEGO® EV3 robotics during afterschool clubs. Thirty teachers and 531 students took…

This Macau study investigates the unwillingness of primary 5 Chinese native students to read in English on a Lexile® Framework based digital reading platform provided by their school, with visible negative consequences on their English reading literacy, and whether or not it is possible for teachers to help improve students' reading literacy by…

This paper reports on a mathematics intervention initiative, "Prepare 2 Learn," designed taking into account research literature and elements of other successful programs. The program was intended to prepare students for their upcoming mainstream mathematics lessons as well as make them aware of the impact they can have on their own…

This paper presents one product of a research report about the promotion of resilience in the school setting in two public secondary schools, located in Mexico and Germany, and its relation with the pupils' multiculturalism. The paper focuses on the need of the results' analysis to identify the school actors' perceptions of the promotion of…

Research (for example Ball, 1988; Philippou & Christou, 1998) have linked teachers' attitudes with classroom practice in teaching mathematics. Previous studies have identified and examined the relationships between different components of teachers' attitudes (Nisbet, 1991). However, a particular criticism of these studies is the lack of…

In this mixed methods study, we use positioning theory to analyze teachers' professional discussions about students' mathematical work over the course of 60 hours of professional development focusing on a learning trajectory. After identifying a category of speech actions that suggested student learning is limited by their age or grade level, a…

This paper presents findings as part of a wider study that investigated the professional knowledge of teachers when teaching mathematics for numeracy in the primary school classroom. This paper focuses on teachers in action as they taught two lessons on multiplication. It outlines the specific pedagogical categories the teachers used and the…

This research report presents the results of a STEM summer program on robotics and game design. The program was part of a three-year study funded by the National Science Foundation. Children in grades four through six participated in a two-week summer camp in 2015 to learn STEM by engaging in LEGO® EV3 robotics and computer-based games using…

Most research on linguistic features of test items negatively impacting English language learners' (ELLs') performance has focused on lexical and syntactic features, rather than discourse features that operate at the level of the whole item. This mixed-methods study identified two discourse features in 162 multiple-choice items on a standardized…

This mixed-methods study examines effects of implementing a mock edTPA task on prospective elementary teachers' perceptions of teaching effectiveness. Results from the Mathematics Teaching Efficacy Beliefs Instrument document a significant change in participants' beliefs that they can effectively teach mathematics. Qualitative results illuminate…

This paper describes part of a mixed-methods study comparing the effectiveness of an individual, conceptual instruction based, tuition program delivered face-to-face and by personal videoconferencing (PVC) for 30 upper primary and middle school students with mathematical learning difficulties (MLDs). The experimental intervention targeted number…
