Precursors of metamemory in young children: the role of theory of mind and metacognitive vocabulary

This paper describes findings of a longitudinal study that was carried out to examine relationships among different aspects of young children's cognitive development, namely, theory of mind, metacognitive vocabulary, and metamemory, which seem theoretically connected but so far have not been studied simultaneously. In total, 174 children were included in the present analyses who were about 4;6 years of age at the first measurement point. Children were tested at four time points, separated by a testing interval of approximately half a year. At the first time of testing, children completed a set of theory of mind tasks. At each of the following measurement points, measures of metacognitive vocabulary and general vocabulary as well as metamemory were given. Overall, the findings show that theory of mind performance assessed at the age of 4;6 predicts metacognitive knowledge assessed about one and a half years later. Furthermore, they point to a reciprocal relationship between metacognitive vocabulary and metamemory in that comprehension of metacognitive vocabulary predicted later metamemory and, conversely, metamemory significantly predicted later comprehension of metacognitive verbs. This research was supported by a grant from the German Research Foundation (SCHN 315 /20–7) to the German Research Group on Cognitive Development.     

Strategic escapes: Negotiating motivations of personal growth and instrumental benefits in the decision to study abroad

Studying abroad is one way in which university students can develop personal capital and distinguish themselves in an increasingly congested graduate labour market. Data show that studying abroad indeed provides employment benefits, with evidence pointing to even greater positive effects for students from low socio‐economic status backgrounds. Focusing on a group of Canadian students about to embark on a study exchange, we find no evidence that career‐instrumental reasons played a role in participants’ decisions to study abroad. Rather, they sought personal growth and escape from the everyday frustrations of being an undergraduate student. We argue, however, that these motivations nonetheless have to be understood as strategic, since going on a study exchange abroad allows students to escape temporarily, while ‘staying in the game’ of becoming credentialed at home. We discuss the role of socio‐economic status, as well as the policy implications of these findings.

Comparisons of observed process quality in German and American infant/toddler programs

Observed process quality in infant/toddler classrooms was compared in Germany (n = 75) and the USA (n = 219). Process quality was assessed with the Infant/Toddler Environment Rating Scale(ITERS) and parent attitudes about ITERS content with the ITERS Parent Questionnaire (ITERSPQ). The ITERS had comparable reliabilities in the two countries and similar factors were found. Content validity of the ITERS is supported in both countries by similarly high ITERSPQ importance scores. ITERS classroom mean scores are similar (Germany = 3.21; USA = 3.36), but a higher US standard deviation is found. A discriminant analysis revealed differences between countries on a bipolar dimension, with US programs characterized by higher scores on custodial issues while German programs have higher scores on educational aspects. Spearman rank order correlations were completed on ITERSPQ importance scores and observed ITERS scores, showing an association only in the USA. Results are discussed in terms of the parental values and infrastructures found in the two countries.

La qualité de processus observée dans les salles de classe des Enfants/Petits Enfants a été comparée en l’Allemagne (n = 75) et aux Etats‐Unis (n = 219). La qualité de processus a été évaluée avec l’Échelle d’Évaluation de l’Environnement des Enfants/Petits Enfants (ITERS) et les attitudes des parents au sujet du contenu de l’ITERS avec le Questionnaire d’ITERS pour les Parents (ITERSPQ). L’ITERS a eu fiabilités comparables dans les deux pays et des facteurs semblables ont été trouvés. La validité du contentu de l’ITERS est soutenue dans les deux pays par des points sur l’importance d’ITERSPQ pareillement hauts. Les points moyens ITERS de la salle de classe sontsemblables, (Allemagne = 3.21 ; Etats‐Unis = 3.36), mais un écart type plus élevé pour les Etats‐Unis est trouvé. Une analyse discriminante a indiqué des différences entre les pays sur une dimension bipolaire, avec les programmes des Etats‐Unis caractérisés par de points plus hauts sur la question de la garde tandis que les programmes allemands ont de points plus hauts sur des aspects éducatifs. Des corrélations Spearman d’ordre de rang ont été accomplies sur les points d’importance ITERSPQ et on a observé des points d’ITERS montrer une association seulement pour les Etats‐Unis. Des résultats sont discutés en termes de valeurs et infrastructures parentales trouvées dans les deux pays.

La calidad de proceso observada en salas de clase de infantes/niños pequeños fue comparada en Alemania (n = 75) y los E.E.U.U. (n = 219). La calidad de proceso fue determinada con la Escala para Evaluar el Ambiente del Infante/ Niño pequeño (ITERS) y las actitudes de los padres hacia el contenido del ITERS con el Cuestionario ITERS para los Padres (ITERSPQ). El ITERS tenía confiabilidades comparables en los dos países y se encontraron factores similares. La validez del contenido del ITERS es apoyada en ambos países por los puntajes sobre la importancia del ITERSPQ que son semejantemente altos. Los puntajes medios ITERS de la sala de clase son similares, (Alemania = 3.21; E.E.U.U. = 3.36), pero se encuentra una desviación estándar más alta con los E.E.U.U. Un análisis discriminante reveló diferencias entre los países en una dimensión bipolar, con los programas de los E.E.U.U. caracterizados por puntajes más altos en el área de la custodia mientras que los programas alemanes tienen puntajes más altos en los aspectos educativos. Las correlaciones Spearman sobre el orden de rango fueron completadas en los puntajes sobre la importancia de ITERSPQ y se observaron puntajes de ITERS demostrando una asociación solamente en los E.E.U.U. Los resultados se discuten en términos de los valores parentales e infraestructuras encontradas en los dos países.     

Just do it! Study time increases mathematical achievement scores for grade 4-10 students in a large longitudinal cross-country study

Decades of research produced inconsistent findings on whether study time can lead to achievement gains in mathematics. Data generated by more than six thousand students from three different countries who solved more than 1.1 million problem sets using a dedicated mathematics software are analyzed regarding the effect of study time on students’ achievements in mathematics. Results showed that more study time led to higher performance scores in mathematics. Further analyses revealed that low-performing students in the first school year (2017-2018) who increased their study time in the following year (2018-2019) revealed greatest gains in performance in the same school year (2018-2019) and even in the year after (2019-2020). Finally, results replicated previous observations of robust performance scores within students over the three school years, with performance scores in 2017-2018 predicting those of 2018-2019 which predicted those of 2019-2020. These results support the idea that students, in particular low-performing students, can boost their academic abilities to upper levels when increasing their study time.

     

Protecting knowledge: How legal requirements to reveal information affect the importance of secrecy

Most firms use secrecy to protect their knowledge from potential imitators. However, the theoretical foundations for secrecy have not been well explored. We extend knowledge protection literature and propose theoretical mechanisms explaining how information visibility influences the importance of secrecy as a knowledge protection instrument. Building on mechanisms from information economics and signaling theory, we postulate that secrecy is more important for protecting knowledge for firms that have legal requirements to reveal information to shareholders. Furthermore, we argue that this effect is contingent on the location in a technological cluster, on a firm’s investment in fixed assets and on a firm’s past innovation performance. We test our hypotheses using a representative sample of 683 firms in Germany between 2005 and 2013. Our results support the moderation effect of a technological cluster and a firm’s investment in fixed assets. Our findings inform both academics and managers on how firms balance information disclosure requirements with the use of secrecy as a knowledge protection instrument.     

A Place to Protest

The national media converged on Baltimore, Charleston, and Ferguson, Missouri, in 2014 and 2015 to cover protests in response to police violence toward African American males. Although national and local media covered the events and the aftermath, alternative media sought to provide additional viewpoints and spur readers to respond. This study analyzed the practices, content, and public discourse connected to alternative weekly newspapers in Baltimore, Charleston, and St. Louis. The study examined whether the publications reflected ideal roles of alternative media, including representing different viewpoints, using non-traditional methods of content, and providing a space for the public to challenge systems of power and oppression. The authors also studied the online forums associated with all three publications, including each organization’s website and Facebook page, as potential spaces for alternative publics to emerge around a shared interest in collective action. The publications showed some characteristics of the ideal form of alternative media, but most lacked the diverse voices and critical calls to action needed to represent the normative standard. The discourse the news organizations spurred also fell short of the ideal. The forums lacked rational and critical engagement, and commenters largely failed to promote sincere attempts to engage in community conversation.     

Accuracy of elevation recording using sport watches while walking and running on hilly and flat terrain

Elevation gain (EG) is a significant contributor to the total workload in many endurance sports. Hence, the aim of this study was to evaluate the accuracy of elevation recording as assessed by popular sport watches. Eighteen participants walked and ran at different speeds in various weather conditions in two terrain types: on a hilly 2490 m course with a total EG of 90 m and on a flat 1200 m outdoor track with 0 m EG. In total, 180 recordings from each sport watch were analyzed and compared according to two processing types: filtered and unfiltered EG data. Compared to the reference values, regarding default settings, on hilly terrain, EG was underestimated by ?3.3 to ?9.8 %, and on flat terrain, EG was overestimated by 0.0–4.8 m per 1200 m. These errors could be reduced to ?3.3 to +0.4 %, when filtering conditions were adjusted according to the terrain. Gait speed (ranging from 1.47 to 4.89 m s^?1) or fluctuations in weather conditions between- or within-trials did not influence EG accuracy. A straightforward comparison between manufacturers is hampered as the filter conditions set by default differ. In conclusion, all devices measure EG adequately; however, the displayed default feedback on EG data is not always the most accurate measurement. Consequently, accuracy in elevation recordings could be increased if users appropriately post-process EG data.
