In this study, 80 ninth-grade students enrolled in Algebra I from a high school in south Texas completed the Implicit Theories of Intelligence Scale for Children (ITIS) Survey and the Attitudes Toward Mathematics Inventory (ATMI) Survey, before and after a set of interventions. The students were divided into one of four groups, three with applied…

Background/Context: As part of a national movement to eliminate a global tracking system that disproportionately assigned underserved students to low-level math classes, the Chicago Public Schools (CPS) mandated academic algebra for all students entering high school in 1997. The results were disappointing: low-skill students experienced elevated…

This quantitative study examined the impact of a multi-subject double-dose STEM intervention on the academic achievement of underprepared 9th-grade males. The intervention consisted of heterogeneously grouped core classes of Algebra 1 and biology accompanied by a second multi-subject (Algebra 1 and biology) support class. This nine-week study did…

Our research with Grade 9 learners at a school in Soweto was conducted to explore learners' understanding of fundamental fraction concepts used in applications required at that level of schooling. The study was based on the theory of constructivism in a bid to understand whether learners' transition from whole numbers to rational numbers enabled…

The problem addressed in this study was that teachers underestimate the benefits of technology usage in grade nine Algebra mathematics classrooms. The purpose of this quantitative quasi-experimental study was to examine how the use of a supplemental digital mathematics tool affected achievement scores among grade nine Algebra mathematics students…

This study investigated the effect a computer intervention program has on student proficiency in the Algebra 1 End of Course (EOC) examination. This study utilized the intervention math program IXL Math, a computerized program that targets individual students' skill practice and supports students' need to accelerate mastery of Algebra 1 skills in…

This study investigates the impact of a professional development programme in formative assessment (FA) for high school mathematics teachers. Through a collaborative approach between researchers and in-service teachers, a 16-week online course was designed focusing on feedback strategies, peer co-assessment, and student engagement. A mirrored…

We investigated how students' strategic knowledge about situational (pictorial) drawings and mathematical (schematic) drawings affects drawing accuracy and modeling competencies in the domain of geometry. We conducted a pre-posttest experimental study with 473 students in grade 9. Students were randomly assigned to one of three treatment…

The purpose of this systematic review was to examine the effectiveness of proportional reasoning interventions for students with learning disabilities (LD) or mathematics difficulty (MD). We evaluated fifth to ninth grade interventions on proportional reasoning content, instructional features, and disability and difficulty identification. The nine…

This study employed student choice and tiered worksheets as strategies of differentiated instruction on Quadratic Equations in addressing students' non-compliance with assignments in a flipped classroom. In each lesson, students choose among the instructional materials with guide questions to assist them in focusing on key areas during the…

The virtual-representational-abstract (VRA) instructional sequence presents as a viable mathematics intervention for students with disabilities, including students with autism spectrum disorder (ASD). Yet, to date, all research has been conducted face-to-face with students. However, virtual manipulatives provide an opportunity for educators to…

Purpose: This paper aimed to present the integration of contextualisation in the Department of Education (DepEd) existing module using mobile applications and to find out the influence of the contextualised module with mobile applications (CMMA) entitled Geometry Techy on learners' mathematics performance. Method: The module used…

The article reports an empirical study on the introduction of elementary probabilistic concepts in school, focusing on tasks related to the psychological tradition of heuristics and biases. The concepts involved were studied using an extensional natural frequencies approach. We describe the school intervention conducted in an interaction across…

This article discusses how mathematics didactics can be inspired by and further developed through responsive pedagogy, understood as feedback directed at self-regulation and self-efficacy, in mathematics teaching. The authors explain the rationale behind an intervention model for improving mathematics teachers' feedback practices. The model is a…

We describe results of a long-term design experiment focused on promoting mathematics learning among multilingual ninth graders classified as English Learners. The intervention at a linguistically diverse public high school in the US focused on a unit introducing concepts related to linear rates of change. We analyze results from a…
