The Relations of Emotionality and Regulation to Children's Anger-related Reactions

The purpose of this study was to examine the relations of emotionality (intensity and negative emotion) and regulation (attentional control, mode of coping) to preschoolers' naturally occurring anger reactions. School personnel's ratings of 4–6-year-olds' constructive coping and attentional control were associated with boys' constructive anger reactions whereas their ratings of acting out versus avoidant coping, emotional intensity, and anger intensity generally were correlated with low levels of constructive reactions to anger. Mothers' reports of children's constructive coping and low emotional intensity were associated with children's use of nonabusive language to deal with anger, whereas aggressive coping and negative emotionality were associated with escape behavior when angered. The findings are consistent with the conclusion that individual differences in emotionality and regulatory skills are associated with children's constructive versus nonconstructive anger reactions.     

Effect of bike-fit in the perception of comfort,fatigue and pain

ABSTRACT

The aim of this study was to assess the influence of different bike positions on the perception of fatigue, pain and comfort. Twenty cyclists underwent three tests that involved cycling for 45 min at their individual 50% peak aerobic power output while adopting different positions on the bike. Participants performed the cycling tests adopting three positions defined by two parameters (knee flexion angle [20°, 30°, 40°] and trunk flexion angle [35°, 45°, 55°]) in random order. Angles were measured using a 2D motion analysis system during cycling and applying Fonda’s correction factor. Perceptions of comfort, fatigue and pain were reported before the end of each test. The combination of 40° knee flexion and 35° trunk flexion was perceived as the most uncomfortable position. Moreover, greater knee flexion had a negative effect on trunk comfort, accompanied by greater levels of fatigue and pain perception in the anterior part of the thigh and knee. In conclusion, cyclists perceived the most comfortable position to be when the saddle height was within the recommended knee angle (30° calculated from the offset position or 40 ± 4.0° of absolute value). Upright trunk was found to be the most comfortable position for recreational cyclists, where aerodynamics is not so important. Cyclists’ bike perceptions should be taken into account when it comes to choosing the most beneficial position, since this can play a role in injury prevention and enhance cycling performance.     

Vibrant student voices: exploring effects of the use of clickers in large college courses

Teachers have begun using student response systems (SRSs) in an effort to enhance the learning process in higher education courses. Research providing detailed information about how interactive technologies affect students as they learn is crucial for professors who seek to improve teaching quality, attendance rates and student learning. This study investigates social, educational and emotional effects of the use of SRSs – clickers – at the University of Colorado at Boulder. Methods include participant observation, survey data from over 2000 students enrolled in three semesters of General Chemistry, and in‐depth interviews exploring the nature of student experiences with clickers. Findings suggest clickers significantly alter the social environment experienced by students as they learn. Clickers create learning environments characterized by greater activity, cooperation and conceptual application compared to traditional, lecture‐based instruction. Gender also influences whether students choose to work with peers during clicker‐prompted interaction. The qualitative analysis presented here extends upon themes identified in existing research on the effects of clickers for learning.     

Becoming Data Driven: The Influence of Teachers’ Sense of Efficacy on Concerns Related to Data-Driven Decision Making

Data-driven decision-making (DDDM) reform has proven to be an effective means for improving student learning. However, little DDDM reform has happened at the classroom level, and little research has explored variables that influence teacher adoption of DDDM. The authors propose a model in which teachers’ sense of efficacy for the skills that support classroom-level DDDM and DDDM anxiety significantly influenced teachers’ DDDM efficacy, which then influenced collaboration concerns that influenced refocusing concerns. The authors used structural equation modeling to analyze data on 537 teachers in order to validate this hypothesized model. Results supported this model and are discussed.     

Interacción y símbolo en autistas

Resumen

El análisis del autismo, desde una perspectiva interaccionista, pone de manifiesto la falta de fundamento de muchas de las posiciones «cognitivistas» y «afectivistas», mantenidas tradicionalmente en la interpretación del sindrome, y la escasa eficacia de muchos procedimientos terapéuticos basados en tales interpretaciones. La comparación del desarrollo interactivo del niño normal con el del niño autista permite una interpretación más adecuada del sindrome y sugiere vías terapéuticas para su tratamiento eficaz.     

Primary grade students engage in creative word play through traditional and hands-on methods

Word play is an important skill allowing product names, show titles, jokes, poetry and other writings or orations to be interesting, entertaining and well-remembered. This pretest–posttest counterbalanced study compared two instructional approaches for teaching second and third grade students (n = 71) word play skills. Students at a public elementary school in Iowa, United States studied vowel patterns and rhyming as part of the regular school curriculum for literacy through two conditions: a traditional format of reading, pocket charts, worksheets and oral discussion; versus a more concrete approach of arranging objects and corresponding word cards in a chart-like formation. There was no significant difference in student performance between the conditions but an attitude survey indicated that a large majority of students preferred the object boxes for understanding of word play concepts and task enjoyment.     

Una propuesta de lenguaje exclusivamente gráfico para la comunicación humana

A mediados de este siglo apareció en Occidente toda una generación de lenguajes gráficos «artificiales» (diseãados ex novo y globalmente). La iniciativa fue entonces de los diseñadores y esa tradición ha continuado entre ellos. Los educadores y psicopedagogos retomaron alguno de ellos (como el Bliss) y han iniciado otra vía de desarrollo de estos lenguajes gráficos modernos. El autor presenta aquí un trabajo de creación en esta última línea.
