  Reading comprehension self-efficacy and mathematical problem-solving in primary education: a serial mediation model through mathematical reasoning and critical thinking

  Filiz, Tunahan; Kaplan, Kadir

  Introduction Mathematical problem-solving is fundamental for academic success and real-life challenges and involves more than procedural and computational skills. As most primary school mathematics problems are text-based, reading comprehension self-efficacy may be closely associated with students' performance in mathematical problem-solving. Grounded in Albert Bandura's social cognitive theory, this study examined the associations between reading comprehension self-efficacy and mathematical problem-solving, focusing on the sequential indirect associations involving of mathematical reasoning and critical thinking.Methods A quantitative, correlational research design was employed. The sample consisted of 518 fourth-grade students from 14 provinces across seven regions of T & uuml;rkiye. Data were collected using validated scales measuring reading comprehension self-efficacy, critical thinking, mathematical reasoning, and mathematical problem-solving skills. Data were analyzed using correlation analysis and regression-based mediation analysis.Results The findings revealed that mathematical reasoning and critical thinking partially accounted for the association between reading comprehension self-efficacy and mathematical problem-solving. The findings indicated significant indirect effects through critical thinking skills (beta = 0.18, K2 = 0.23), mathematical reasoning skills (beta = 0.04, K2 = 0.19), and the sequential pathway from mathematical reasoning to critical thinking (beta = 0.01, K2 = 0.03). Although the sequential mediation effect was statistically significant, its effect size was relatively small compared with the individual mediation effects, particularly that of critical thinking skills.Discussion These results highlight the interconnected roles of foundational cognitive processes in relation to higher-order mathematical problem-solving skills. The study contributes to the literature by emphasizing the relevance of considering reading comprehension self-efficacy, mathematical reasoning, and critical thinking as interconnected factors in early mathematics education.

  Strategy instruction integrated with realistic mathematics education: A design-based research on teaching word problem solving to students with learning disabilities

  Fılız, Tunahan; Öztel, Nur Çağlayan

  This study used a design-based research method to explore how to design realistic mathematics education principles integrated into strategy instruction for teaching word problem solving to students with learning disabilities. The study was divided into two iterative research phases lasting 3 semesters in which the differentiation of word problem solving strategy steps for 12 third-grade students with learning disabilities was explored. During the two iterations, a combination of quantitative and qualitative data collection and analysis procedures were used to examine the impact of the designed strategies on the word problem solving achievement of students with learning disabilities and to explore students' feedback on the worksheets. After two designbased iteration phases, it was concluded that the redesigned STAR worksheets with realistic mathematics education significantly increased the word problem solving achievement of students with learning disabilities. This design, which increased students' motivation and enhanced classroom interaction, also improved students’ overall problem solving performance and discussion participation. Possible studies for the next phases of the design-based research study are also discussed.

  The effect of cognitive strategy instruction enriched with active learning techniques on word problem-solving skills of students with learning disabilities

  Filiz, Tunahan

  This study aimed to investigate the effectiveness of cognitive strategy instruction (CSI) enriched with active learning (AL) techniques in teaching word problem solving to primary school students with learning disabilities, as well as to examine the overall instructional process. Word problem solving is the process of using contextual information from real-life or fictional situations to develop mathematical solutions. The research was designed with an embedded mixed-method model. The quantitative phase included 30 third-grade students with learning disabilities, while the qualitative phase involved six randomly selected students from the experimental group. Quantitative analyses revealed that students in the experimental group showed significantly higher achievement in problem-solving tests, indicating the positive impact of CSI enriched with AL techniques. Qualitative findings highlighted increased class participation, enhanced collaboration, and more positive attitudes toward mathematics. Furthermore, teacher and peer interactions supported the problem-solving process, and the use of tools promoting mathematical thinking strengthened performance. The results demonstrated that CSI enriched with AL techniques encouraged strategic thinking and the generation of alternative solutions in word problem solving. The study, limited to three learning outcomes within the third-grade mathematics curriculum in Turkey, suggests that teachers should adapt and implement such instructional approaches across other mathematical domains, given the students’ positive experiences and outcomes.

  A Psychometric Analysis of The Mathematics Learning Disability Screening Scale Developed Through DSM-5

  Filiz, Tunahan; Çelik, Ahmet

  Purpose: This study, it was aimed to develop a valid and reliable measurement tool by evaluating the psychometric properties of the Mathematics Learning Disabilities Screening Scale (MLDSS) for elementary and secondary school students. In this context, a measurement tool that is culturally and linguistically appropriate for the Turkish context and overcomes the limitations of translated scales was developed. Design/Methodology/Approach: The study was conducted as a scale development study within a survey research design. The scale's items were developed based on DSM-5 criteria and an extensive literature review. The sample consisted of 644 students, identified by their teachers, from 120 schools across Türkiye's seven geographical regions. The psychometric properties of the scale were evaluated using Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA), along with internal consistency (Cronbach's Alpha) and test-retest reliability analyses. Findings: The EFA results revealed a three-factor structure (Number Sense, Calculation, and Mathematical Reasoning) that explained 68.5% of the total variance. The CFA confirmed this structure, with goodness-of-fit indices indicating an excellent model fit (e.g., CFI = .95, IFI = .95, RMSEA = .069, χ²/df = 2.41). The scale demonstrated high internal consistency (Cronbach's Alpha = .93) and strong test-retest reliability (r = .90). Highlights: The mathematics learning disability screening scale is a valid and reliable instrument developed for elementary and secondary school students. Its three-factor structure is consistent with modern theories of mathematics learning disabilities and its strong psychometric properties make it a valuable tool for educators and experts in early identification and intervention planning.

  Effects of Instructional Intervention Programs on Reading Skills of Students with Reading Difficulties

  Filiz, Tunahan; Demir, Mustafa; Kaya, Metin

  Evaluating the impacts of instructional intervention programs on students with reading difficulties is important for setting guidelines to teachers, researchers, and policy-makers. The aim of this research is to examine how these interventions initiatives impact the reading abilities of students diagnosed with reading difficulties (RD). 38 impact sizes obtained from 17 meta-analysis studies are analysed with second order meta-analysis method. These studies included are carried out between 1999 and 2023, and focus on the effects of instructional intervention programs on the reading abilities of individuals who experience difficulties in reading. Finally, in the analysis, it is decided that the impact of instructional intervention programmes on students with RD is mid-range (g=.50). Also, instructional intervention programs caused important differences according to the type of intervention, quality level, and the year of publication on the reading abilities of individuals with RD. It is determined that comprehension strategy instruction (CSI) intervention programs are more efficient than foundational reading skills instruction (FRSI) and multicomponent instruction (MI) intervention programs. It is necessary to make more experimental studies to determine if instructional interventions cause meaningful differences in terms of the characteristics of participant students. It can also be beneficial to carry out primary meta-analysis studies that test the impact of instructional interventions on the reading abilities of individuals with RD who are determined with standardized tests.
