Does Taekwondo improve children's self-regulation? If so, how? A randomized field experiment.

Emerging evidence suggests interventions can improve childhood self-regulation. One intervention approach that has shown promise is Taekwondo martial arts instruction, though little is known about its acceptability among stakeholders or its mechanisms of effect. We extend evidence on Taekwondo interventions in three ways: (a) testing the efficacy of a standard introductory course of Taekwondo, (b) assessing the acceptability of Taekwondo instruction among school children, and (c) investigating two self-regulatory mechanisms by which Taekwondo may operate (executive functions and motivation). This article reports findings from a randomized control trial implementing a standard 11-week beginners' course of Taekwondo. Participants were from a mixed-sex, nonselective U.K. primary school (N = 240, age range 7 to 11 years). Measures of self-regulation included teacher-rated effortful control, impulsivity, prosocial behavior, and conduct problems; computer-based assessments of executive functions; and child self-reported expectancies and values to use self-regulation. Postintervention, children in the Taekwondo condition were rated by teachers as having fewer symptoms of conduct problems and better effortful control (specifically attentional control), and they also had better executive attention assessed by a flanker task. Effects were not found for teacher-rated inhibitory control, activation control, impulsivity, and prosocial behavior or for assessments of response inhibition, verbal working memory, and switching. Taekwondo was rated very positively by children. Finally, there was evidence that children who completed Taekwondo classes reported higher expectancies and values to use self-regulation and that expectancies and values mediated intervention effects on self-regulation. We conclude that short standard Taekwondo courses are well received by pupils, improve attentional self-regulation, and reduce symptoms of conduct problems.

Cross-Domain Trajectories of Students' Ability Self-Concepts and Intrinsic Values in Math and Language Arts.

Different cross-domain trajectories in the development of students' ability self-concepts (ASCs) and their intrinsic valuing of math and language arts were examined in a cross-sequential study spanning Grades 1 through 12 (n = 1,069). Growth mixture modeling analyses identified a Moderate Math Decline/Stable High Language Arts class and a Moderate Math Decline/Strong Language Arts Decline class for students' ASC trajectories. Students' intrinsic value trajectories included a Strong Math Decline/Language Arts Decline Leveling Off, a Moderate Math Decline/Strong Language Arts Decline, and a Stable Math and Language Arts Trajectories class. These classes differed with regard to student characteristics, including gender, family background, and math and reading aptitudes. They also resulted in different high school math course enrollments, career aspirations, and adult careers.

Gender Stereotypes in a Children's Television Program: Effects on Girls' and Boys' Stereotype Endorsement, Math Performance, Motivational Dispositions, and Attitudes.

Television programs are a central part of children's everyday lives. These programs often transmit stereotypes about gender roles such as "math is for boys and not for girls." So far, however, it is unclear whether stereotypes that are embedded in television programs affect girls' and boys' performance, motivational dispositions, or attitudes. On the basis of research on expectancy-value theory and stereotype threat, we conducted a randomized study with a total of 335 fifth-grade students to address this question. As the experimental material, we used a television program that had originally been produced for a national TV channel. The program was designed to show children that math could be interesting and fun. In the experimental condition, the program included a gender stereotyped segment in which two girls who were frustrated with math copied their math homework from a male classmate. In the control condition, participants watched an equally long, neutral summary of the first part of the video. We investigated effects on boys' and girls' stereotype endorsement, math performance, and different motivational constructs to gain insights into differential effects. On the basis of prior research, we expected negative effects of watching the stereotypes on girls' performance, motivational dispositions, and attitudes. Effects on the same outcomes for boys as well as children's stereotype endorsement were explored as open questions. We pre-registered our research predictions and analyses before conducting the experiment. Our results provide partial support for short-term effects of gender stereotypes embedded in television programs: Watching the stereotypes embedded in the video increased boys' and girls' stereotype endorsement. Boys reported a higher sense of belonging but lower utility value after watching the video with the stereotypes. Boys' other outcome variables were not affected, and there were also no effects on girl's performance, motivational dispositions, or attitudes. Results offer initial insights into how even short segments involving gender stereotypes in television shows can influence girls' and boys' stereotype endorsement and how such stereotypes may constitute one factor that contributes to gender differences in the STEM fields.

How Do Perceptions of Importance Support From a Reading Intervention Affect Students' Motivation, Engagement, and Comprehension?

Interventions can enhance students' motivation for reading, but few researchers have assessed the effects of the specific motivation-enhancing practices that comprise these interventions. Even fewer have evaluated how students' perceptions of different intervention practices impact their later motivation and academic outcomes. In this study, we utilized data from a study of Concept-Oriented Reading Instruction, a program designed to enhance seventh-grade students' reading comprehension and motivation. We examined the effects of students perceiving one practice from this intervention, emphasizing the importance of reading, which was designed to enhance their task values for reading (Eccles-Parsons et al, 1983). Unexpectedly, structural equation modeling analyses showed that students' perceptions of importance support predicted their later competence-related beliefs, but not their task values. Students' competence-related beliefs predicted their reading comprehension and behavioral engagement, whereas students' task values predicted reading engagement. However, there were no significant indirect effects of perceiving importance support on students' reading outcomes.

The Role of Family Characteristics for Students' Academic Outcomes: A Person-Centered Approach.

Using data from 1,571 ninth-grade students (Mage  = 14.62) from 82 academic track schools in Germany and their predominantly Caucasian middle-class parents, configurations of different family characteristics reported by parents were investigated. Latent profile analyses considering academic involvement, family interest, parents' self-concept, child's need for support, and parents' time and energy identified average, indifferent, motivated and engaged, motivated and disengaged, and involved families. Cross-sectional and longitudinal associations with students' motivational (self-concept, effort, and interest) and achievement outcomes (achievement test and grades) in math were analyzed. Students from families classified as motivated and disengaged showed higher initial levels motivation and achievement. Over 5 months, these students also showed an increase in self-concept and higher achievement than students from other family types.

Robin Hood effects on motivation in math: Family interest moderates the effects of relevance interventions.

Using a cluster randomized field trial, the present study tested whether 2 relevance interventions affected students' value beliefs, self-concept, and effort in math differently depending on family background (socioeconomic status, family interest (FI), and parental utility value). Eighty-two classrooms were randomly assigned to either 1 of 2 intervention conditions or a control group. Data from 1,916 students (Mage = 14.62, SDage = 0.47) and their predominantly Caucasian middle-class parents were obtained via separate questionnaires. Multilevel regression analyses with cross-level interactions were used to investigate differential intervention effects on students' motivational beliefs 6 weeks and 5 months after the intervention. Socioeconomic status, FI, and parental utility values were investigated as moderators of the intervention effects. The intervention conditions were especially effective in promoting students' utility, attainment, intrinsic value beliefs, and effort 5 months after the intervention for students whose parents reported lower levels of math interest. Furthermore, students whose parents reported low math utility values especially profited in terms of their utility and attainment math values 5 months after the intervention. No systematic differential intervention effects were found for socioeconomic status. These results highlight the effectiveness of relevance interventions in decreasing motivational gaps between students from families with fewer or more motivational resources. Findings point to the substantial importance of motivational family resources, which have been neglected in previous research. (PsycINFO Database Record

Fostering adolescents' value beliefs for mathematics with a relevance intervention in the classroom.

Interventions targeting students' perceived relevance of the learning content have been shown to effectively promote student motivation within science classes (e.g., Hulleman & Harackiewicz, 2009). Yet, further research is warranted to understand better how such interventions should be designed in order to be successfully implemented in the classroom setting. A cluster randomized controlled study was conducted to test whether ninth-grade students' value beliefs for mathematics (i.e., intrinsic value, attainment value, utility value, and cost) could be fostered with relevance interventions in the classroom. Eighty-two classrooms were randomly assigned to 1 of 2 experimental conditions or a waiting control condition. Both experimental groups received a 90-min intervention within the classroom on the relevance of mathematics, consisting of a psychoeducational presentation and relevance-inducing tasks (either writing a text or evaluating interview quotations). Intervention effects were evaluated via self-reports of 1,916 participating students 6 weeks and 5 months after the intervention in the classroom. Both intervention conditions fostered more positive value beliefs among students at both time points. Compared with the control condition, classes in the quotations condition reported higher utility value, attainment value, and intrinsic value, and classes in the text condition reported higher utility value. Thus, stronger effects on students' value beliefs were found for the quotations condition than for the text condition. When assessing intervention effects separately for females and males, some evidence for stronger effects for females than for males was found.

Developmental changes in using verbal self-cueing in task-switching situations: the impact of task practice and task-sequencing demands.

In this study we examined whether developmental changes in using verbal self-cueing for task-goal maintenance are dependent on the amount of task practice and task-sequencing demands. To measure task-goal maintenance we applied a switching paradigm in which children either performed only task A or B in single-task blocks or switched between them on every second trial in mixed-task blocks. Task-goal maintenance was determined by comparing the performance between both blocks (mixing costs). The influence of verbal self-cueing was measured by instructing children to either name the next task aloud or not to verbalize during task preparation. Task-sequencing demands were varied between groups whereas one group received spatial task cues to support keeping track of the task sequence, while the other group did not. We also varied by the amount of prior practice in task switching while one group of participants practiced task switching first, before performing the task naming in addition, and the other group did it vice versa. Results of our study investigating younger (8-10 years) and older children (11-13 years) revealed no age differences in beneficial effects of verbal self-cueing. In line with previous findings, children showed reduced mixing costs under task-naming instructions and under conditions of low task-sequence demands (with the presence of spatial task cues). Our results also indicated that these benefits were only obtained for those groups of children that first received practice in task switching alone with no additional verbalization instruction. These findings suggest that internal task-cueing strategies can be efficiently used in children but only if they received prior practice in the underlying task so that demands on keeping and coordinating various instructions are reduced. Moreover, children benefitted from spatial task cues for better task-goal maintenance only if no verbal task-cueing strategy was introduced first.
