Educational goals and motives as possible mediators in the relationship between social support and academic achievement

Perceived social support has been widely recognized as having beneficial effects on a person’s development, and adolescence is no exception. The objective of this article is to go beyond this “stereotypical” vision of friendship by showing that social support does not always have a positive and direct effect on adolescents’ academic achievement. We sought to understand whether this relationship is mediated by the educational goals and motives that student value and pursue. If these values do not coincide with the expectations and values that the academic institution seeks to transmit, the influence of social support can become harmful, especially with regard to the students’ academic achievement. Data were collected by means of questionnaires from 676 junior high school students in 9th grade from contrasting academic institutions. We chose to observe each participant’s subjective point of view of three dimensions: social support, academic achievement, and educational goals and motives. The results showed that the relationship between social support and attention and involvement in class was negative and mediated by students’ goals. The adolescents with a high level of social support mainly pursued social goals and neglected achievement and future goals. Consequently, these students were less attentive and involved in class. The results also showed that social support was predictive of students’ investment and interest in personal work and success, but only when the students pursued achievement and future goals.

Contribution of temporal processing skills to reading comprehension in 8-year-olds: evidence for a mediation effect of phonological awareness

This study tested whether the association between temporal processing (TP) and reading is mediated by phonological awareness (PA) in a normative sample of 615 eight-year-olds. TP was measured with auditory and bimodal (visual-auditory) temporal order judgment tasks and PA with a phoneme deletion task. PA partially mediated the association between both auditory and bimodal TP and reading, above nonverbal abilities, vocabulary, and processing speed. PA explained a larger proportion of the association between auditory TP and reading (56% vs. 39% for bimodal TP), and most of the association between bimodal TP and reading was direct. This finding is consistent with a dual-phonological and visual-pathway model of the association between TP and reading in normative reading skills.     

Reliability and Validity of the Flemish Physical Activity Computerized Questionnaire in Adults

The purpose of this study was to investigate the test-retest reliability and concurrent validity of the Flemish Physical Activity Computerized Questionnaire (FPACQ) in employed/unemployed and retired people. The FPACQ was developed to assess detailed information on several dimensions of physical activity and sedentary behavior over a usual week. A triaxial accelerometer, the RT3 Triaxial Research Tracker (RT3), in combination with a written 7-day activity record, was used as the objective criterion measure. In employed/unemployed people, 2-week test-retest reliability for several activity variables calculated from the FPACQ was good to excellent with intraclass correlations (ICCs) ranging from .67 to .99. In retired people ICCs were lower but, except for time spent eating, still fair to excellent, ranging from .57 to .96. Except for time spent in leisure time activities for men and the average energy expenditure related to sports participation in women, correlations between the RT3 and the FPACQ generally supported the relative validity of the FPACQ for employed/unemployed people (r ranging from .37 to .88). Values for retired people were somewhat lower (r ranging from .15 to .85), but most variables still reached at least moderate correlations. Concerning absolute validity, the FPACQ generally overestimated physical activity and underestimated sedentary behavior compared to the RT3. From this study, it can be concluded that the FPACQ is a reliable and reasonably valid questionnaire for assessing different dimensions of physical activity and sedentary behavior.     

Students’ Perception of Risk About Nanotechnology After an SAQ Teaching Strategy

We experimented with teaching nanotechnology in high school within the perspective of citizenship education in science by involving experts in nanotechnology, education, ethics and philosophy. After training, the students debated a Socially Acute Question (SAQ) that they elaborated during the various phases of instruction. The field of SAQs represents a French orientation for the teaching of SocioScientific Issues. We analyzed the interactions of students in the debate to determine their risk perception on nanotechnology. We compared and put their arguments into perspective using various analytical frameworks. We observed two contrasting argumentative tendencies: one reflecting a positivist view that involved an individualistic use of nanotechnology and science and one carrying a critical and humanistic vision of the use of nanotechnology and science.     

Enclothed cognition: putting lab coats to the test

ABSTRACT

Although there has been some success with programmes that aim to increase STEM involvement by women and underserved minorities, science educators continue to seek ways to promote students’ interest in STEM. This study builds on social cognitive career theory (SCCT) and the theory of enclothed cognition to assess the impact of wearing lab coats on 5th-grade students. Students were assigned to a treatment group (that wore lab coats, n = 106) or a control group (that did not wear lab coats, n = 110) for 10 science classes taught by their classroom science teacher. Students were assessed pre and post to the intervention with a survey designed to measure science interest, recognition from others as a science person, science self-efficacy, and STEM career goals. Results showed students’ interest in science was not significantly changed due to wearing the lab coat, but the lab coats did have significant effects on students’ perceived recognition by others as being a science learner. Furthermore, those treatment students with low self-efficacy (compared to those with high self-efficacy) and those with who did not report having access to a parent with a STEM career had significant increases in perceptions of self-efficacy in science.     

Implementing and Integrating Effective Teaching Strategies Including Features of Lesson Study in an Elementary Science Methods Course

Teacher preparation programs have been under attack by policy makers in the last decade, and teacher educators are constantly striving to improve their programs. Yet, there are several research-based practices that have been shown to be effective for developing teachers. In this article, the author summarizes a study in one science methods course that included adaptations and updates of several of these practices integrated with newer strategies featuring elements of Japanese lesson study. Some of these practices include collaboration, critique, revision, and reflection. Video technology is utilized for reflection and to record updated forms of microteaching. The voices of the preservice teachers illustrate the value and challenge of these practices.     

El retraso de origen afectivo: nueva orientación en el enfoque de las deficiencias intelectuales y revisión crítica de la literatura sobre la carencia de cuidados maternos

RESUMEN

Se puede hablar de retraso mental de origen afectivo cuando no se encuentran determinantes biológicos y hay una evidente situación de privación afectiva precoz. La carencia de cuidados maternos provocada por la situación de separación definitiva de la madre podría determinar su desarrollo cognitivo, al incidir en el aprendizaje en curso y en la organización emocional del niño. Se analiza la naturaleza del vínculo madre-hijo desde las diferentes escuelas. Quedan planteadas algunas cuestiones: la posibilidad de que la separación definitiva madre-hijo conlleve en determinados niños una insuficiencia intelectual; a través de qué mecanismos ésto se produce; y la reversibilidad de este proceso. Las contradicciones entre los resultados obtenidos y las divergencias de opinión entre los especialistas nos muestran la complejidad del tema.     

Preschool children’s conversational skills for explaining game rules: communicative guidance strategies as a function of type of relationship and gender

Ten trios of children from 4 to 6 years old were observed in a situation where one child (the expert) who had learned the rules of a game explained these rules to two other children at the same time (the novices): one with whom s/he had a positive relationship and the other with whom her/his relationship was negative. Within this asymmetrical situation created artificially, the children functioned on the basis of a complex tutorial contract. The results indicated that, at these young ages, children are capable to strongly manage three dimensions of the explanatory goal: interactional, ideational (management of the object), and linguistic. However, the errors made by the novices were regulated differently, depending on the type of relationship and gender: the experts in boy trios intervened less frequently when errors were made by the novice with whom the relationship was negative (i.e., the not-friend novice) than with the other novice; conversely, the experts in girl trios intervened less frequently when errors were produced by the novice with whom the relationship was positive (i.e., the friend novice) than with the other novice. An analysis of the communicative strategies observed here highlights early sophisticated pragmatic skills in this interactive assigned design.
