This single-case study assessed the effectiveness of a mnemonic pegword strategy designed to enhance the multiplication fact fluency of three 6th-grade students who demonstrated persistent learning difficulties in mathematics. A nonconcurrent multiple baseline across subjects design was utilized, incorporating 3-5 baseline sessions followed by…

This single-subject design study examines the effectiveness of a Tier 3 math intervention designed to address the academic challenges of three fifth-grade students not meeting minimum proficiency standards in long division. Using the self-regulated strategy development (SRSD) model, the intervention targeted procedural fluency and conceptual…

Background/Objective. This study aimed to assess the effectiveness of a multisensory approach based on the CRA framework in enhancing geometric thinking skills among fourth-grade students with learning difficulties in mathematics. It examined the relationship between sense preferences and performance and investigated how interactions among those…

Fractions are a fundamental component of the school mathematics curriculum, and most students achieve proficiency in these concepts during their elementary education. However, a significant proportion of students still encounter challenges in this area even after entering secondary education, necessitating additional support to prevent further…

Competence with rational numbers is essential for mathematics proficiency in secondary mathematics. However, many students struggle with rational number concepts, and students with mathematics difficulties struggle even more. The purpose of this study was to examine the effects of an intervention that incorporated the use of explicit instruction…

This quasi-experimental study was designed to investigate the initial efficacy of a fraction-vocabulary intervention for Grade 4 students with mathematics difficulty (MD) and to explore its impact on relevant fraction competencies. Thirty-three students were assigned to either the intervention condition (n = 16) or a business-as-usual comparison…

This pilot study examined the feasibility of using worked examples as a mechanism to improve verbal explanations of fractions concepts among Grade 5 students with mathematics difficulties in a small-scale randomized controlled trial (RCT) before scaling up to a large-scale RCT. Students (N = 49) were randomly assigned to a business-as-usual (BAU)…

Through a constructivist teaching experiment, we studied how a 6th-grade student (Adam, pseudonym) struggling in mathematics may reorganize his available additive scheme (count-up-to) into a more advanced scheme involving the decomposition of composite units (break-apart-make-ten, or BAMT). First, we posed a task that led us to infer Adam was yet…

This study examined how mathematics anxiety, trait emotional intelligence, and mathematics self-concept predict calculation fluency, numerical operations, and mathematical reasoning in students with and without mathematics learning difficulties (MLD). Participants (N = 326) were third- to fifth-grade students from China who completed standardized…

The present study used the Early Childhood Longitudinal Study, Kindergarten Class of 2011 (ECLS-K:2011) to examine the bidirectionality and co-occurrence between math achievement and behavioral outcomes of upper elementary school students. We analyzed the cross-lagged relations across four groups of students who had different initiating statuses…

This study examined how word-problem characteristics influenced students' learning and retention of word-problem knowledge during and after an intervention. The participants were 221 fourth-grade students (average age at pretest = 8.8 years) who experienced word-problem difficulties (WPD) and had received a word-problem intervention in third…

The purpose of this study was to evaluate the effects of a simple motivational treatment (consisting of immediate feedback, goal setting, and positive reinforcement) on the reading performance of an 11-year-old boy with learning difficulties. We applied an ABAB reversal design to test the impact of our approach. The dependent measure was the…

In this study, our team observed sixth grade teachers as they taught fractions to students in their mathematics intervention classes to see whether they were including motivational-supportive messages within the framework of Situated Expectancy-Value Theory. Messages in the intervention lessons and teacher transcripts were explored and analyzed,…

Previous studies reported that a substantial number of students with autism spectrum disorder (ASD) encounter challenges in mathematics as they advance through their education. The present study evaluates the mathematical competence of 17 students diagnosed with ASD who were recruited from first through fourth grades in 12 different mainstream…

This exploratory study evaluated the effects of self-regulated strategy development (SRSD) on students' written expression when asked to solve a word problem and explain reasoning. A secondary question evaluated potential for differential effects based on determination of having mathematics difficulty (MD). We implemented a quasi-experimental…
