Developing both conceptual and procedural knowledge is important for students' mathematics competence. This study examined whether U.S. Grade 9 general education mathematics teachers' self-reported use of concept-focused instruction (CFI) and procedure-focused instruction (PFI) were associated differently with ninth graders' algebra achievement…

In response to recent interest in K-12th students' mathematics identity formation and its implications for achievement, the present study examines the relationship between learners' mathematics identity and student achievement while simultaneously accounting for teacher-enacted instructional practices in mathematics. Drawing from HSLS:2009, a…

This study examines the relationship between class size and secondary school students' mathematics achievement focusing on three aspects: (1) the relationship between class size and mean mathematics achievement gains; (2) how relationships differentiate across student groups; and (3) the association between class size and variance in mathematics…

Assessments play a pivotal role in Mathematics education, serving as vital gauges of students' mathematical proficiency and informing teaching strategies. Despite calls for contextualization, some educators still rely on abstract teaching methods and decontextualized tasks. This study aims to address these concerns by designing and implementing a…

Based on expectancy-value theory, this study adopted a person-centred approach to explore the heterogeneous profiles of secondary German and Taiwanese students' mathematical modelling task values, and examined the differences in their mathematical modelling performance, controlling for the variable of intra-mathematical knowledge among the…

This large-scale study characterizes the algebraic learning of a cohort of nearly 800 French students during the last year of middle school (9th grade, 14-15 years old) and examines their evolution in relation to the composition of the classes to which the students belong. Based on the Anthropological Theory of the Didactic (ATD), the study is…

South African children have a right to equitable education free from harm. Still, news of school bullying incidents continues to grab South African news headlines. Creating a safe environment conducive to learning is vital in learners' mathematics achievement (MA). We investigated the association between bullying and Grade 9 MA in South African…

This paper quantifies learning losses between 2020 and 2022 in the Dominican Republic, an upper-middle-income country. The paper uses data from a sample of ninth-grade students who benefited from computer adaptive learning software during this period. This study is among a few to measure actual losses among secondary school students, and it is the…

Background: There is growing interest in studying the co-occurrence of multiple achievement goals and how different goal profiles relate to educational outcomes. Further, contextual aspects of the classroom have been known to influence the goals students pursue but existing studies remain confined within certain traditions and confounded by…

This study examined how adolescents' emotions in mathematics develop over time. Growth curve modeling was applied to longitudinal data collected annually from 2002 to 2006 (Grades 5-9; N = 3425 German adolescents; M[subscript age] = 11.7, 15.6 years at the first and last waves, respectively; 50.0% female). Results indicated that enjoyment and…

Recent research syntheses have identified several potentially high-leverage teaching strategies for improving low-attaining secondary school students' learning of mathematics. These strategies include the structured use of representations and manipulatives and an emphasis on derived facts and estimation. This paper reports on 70 semi-structured…

With growing demand for online courses, it is important to assess the efficacy of quality online virtual instruction. This study investigates the impact of Edmentum's Courseware Algebra I on student achievement using data on 1,205 ninth-grade students from a large urban school district in the Midwest during the 2020-2021 school year. Utilizing a…

Purpose: Mathematical literacy and mathematical problem-solving are crucial abilities that link mathematics content to real life applications, facilitating both mathematics understanding and mathematical processes. The present study aimed to investigate the effectiveness of the STEMEN (STEM and educational neuroscience) teaching model in enhancing…

In poor-performing, resource-constrained education systems, such as South Africa, solutions to improve academic achievement have tended to focus on resources and cognitive factors. An area that requires more attention is the importance of non-cognitive, psychosocial factors and their relationship with academic performance. These factors are…

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…
