Eye tracking is an increasingly popular method in mathematics education. While the technology has greatly evolved in recent years, there is a debate about the specific benefits that eye tracking offers and about the kinds of insights it may allow. The aim of this review is to contribute to this discussion by providing a comprehensive overview of the use of eye tracking in mathematics education research. We reviewed 161 eye-tracking studies published between 1921 and 2018 to assess what domains and topics were addressed, how the method was used, and how eye movements were related to mathematical thinking and learning. The results show that most studies were in the domain of numbers and arithmetic, but that a large variety of other areas of mathematics education research was investigated as well. We identify a need to report more methodological details in eye-tracking studies and to be more critical about how to gather, analyze, and interpret eye-tracking data. In conclusion, eye tracking seemed particularly beneficial for studying processes rather than outcomes, for revealing mental representations, and for assessing subconscious aspects of mathematical thinking.
Alliance is defined as the client-therapist bond and their ability to collaborate on therapeutic activities. Treatment for adolescents with ADHD is rarely studied in terms of alliance. In this study, two cognitive-behavioral treatments (CBT; one structured treatment aimed at planning skills and one less-structured solution-focused treatment, both delivered in the style of Motivational Interviewing) were compared with regard to alliance and alliance-outcome association. The influence of therapist competence on this alliance-outcome association was also evaluated. The alliance between 69 adolescents diagnosed with ADHD and their therapists was measured early in treatment, using the Therapy Process Observational Coding System for Child Psychotherapy-Alliance scale. Observer-rated therapist competence was measured using the Motivational Interviewing Treatment Integrity scale (version 3.1.1.). Outcome variables were the adolescents' reduction in planning problems and ADHD symptoms. The alliance, and, more specifically, collaboration on therapeutic activities, was significantly higher for the more structured CBT (p = .04; moderate effect size). Alliance was not related to outcome in the more structured CBT, while the alliance was positively related to the reduction in planning problems in the less structured CBT. Finally, alliance was a significant mediator between therapist competence and treatment outcome for the less-structured CBT. The clarity and structure of CBT may help facilitate alliance formation for adolescents with ADHD who often have difficulty implementing structure themselves. Therapists may need to invest more in alliance formation in less structured CBT as the alliance affects outcome. Moreover, enhancing therapist competence in less structured CBT may help improve outcomes in less structured CBT, as therapist competence may impact outcome through alliance.
Many studies have examined the cognitive determinants of children's calculation, yet the specific contribution of children's patterning abilities to calculation remains relatively unexplored. This study investigated whether children's ability to complete sequence patterns (i.e., add the missing element into 2-4-?-8) uniquely predicted individual differences in calculation and whether these associations differed depending on the type of stimuli in these sequence patterns (i.e., number, letter, time, or rotation). Participants were 65 children in first and second grade (M = 7.40 years, SD = 0.44). All children completed four tasks of sequence patterning: number, letter, time, and rotation. Calculation was measured via addition and subtraction tasks. We also measured cognitive determinants of individual differences in calculation-namely symbolic number comparison, motor processing speed, visuospatial working memory, and nonverbal IQ-to verify whether patterning predicted calculation when controlling for these additional measures. We observed significant relationships between the patterning dimensions and calculation, except for the rotation dimension. Follow-up regressions, controlling for the aforementioned cognitive determinants of calculation, revealed that the number and time dimensions were strong predictors of calculation, whereas the evidence for the letter dimension was only anecdotal and the evidence for the rotation dimension was nonexistent, suggesting some degree of specificity of different types of sequence patterning in predicting calculation. Symbolic magnitude processing remained a powerful unique correlate of calculation performance. These findings add to our understanding of individual differences in calculation ability, such that sequence patterning could begin to be considered as one of the cognitive skills underlying calculation ability in young children.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
