Effect of acquisition rates on off‐task behavior of kindergarten students while learning sight words

Assessing a student's acquisition rates (ARs) is a reliable way to determine how many new words should be taught in one lesson without reducing retention. Exceeding a student's AR can result in frustration and problem behaviors. The purpose of this study was to examine the effect of AR on the off‐task behavior of kindergarten students while participating in a commonly used sight‐word instruction video. Participants included 39 kindergarten students whose ARs were assessed before showing the sight‐word video. Behavior was measured as on‐ and off‐task using momentary time‐sampling with 10‐s intervals. Results indicated that students' time off task increased after exceeding their ARs, with a noticeable immediate increase. The implications and limitations of these results are discussed. 相似文献

The relationship between the construct of mental attention and “giftedness” is not well established. Gifted individuals could
make effective use of their executive functions and this could be related to their mental attentional capacity. The dialectic
constructivist model developed by Pascual-Leone introduced the concept of mental attention or “effort”, relating it to mental
capacity. The aim of this study is to investigate whether the measurement of mental capacity (M-measurement) is differential
for a group of children with high IQs. 110 students between 4 and 18 years old participated in this study. Some were Gifted
(n=70) and others Non-Gifted (n=40). Wechsler-R Scale and the Figural Intersection Test were administered to all participants.
An interesting pattern was found in the younger groups. The gifted scored higher than the non-gifted in the Figural Intersection
Test and much higher than their theoretical M. The non-gifted scored quite close to their theoretical M (based on age). In
the oldest group, the gifted again achieved higher scores, but now they scored at the theoretical level, and the non-gifted
underperformed. 相似文献

The combined effects of pH and temperature on red pigment production and fungal morphology were evaluated in a submerged culture
of Penicillium purpurogenum GH2, using Czapek-Dox media with d-xylose as a carbon source. An experimental design with a factorial fix was used: three pH values (5, 7, and 9) and two temperature
levels (24 and 34 °C) were evaluated. The highest production of red pigment (2.46 g/L) was reached with a pH value of 5 and
a temperature of 24 °C. Biomass and red pigment production were not directly associated. This study demonstrates that P. purpurogenum GH2 produces a pigment of potential interest to the food industry. It also shows the feasibility of producing and obtaining
natural water-soluble pigments for potential use in food industries. A strong combined effect (p<0.05) of pH and temperature was associated with maximal red pigment production (2.46 g/L). 相似文献

This article reinforces the use of research for faculty who prepare K-12 educators and leaders for social justice. The author conceptualizes auto-ethnography as a form of professional development and maintains that faculty must first experience an internal revolution before they can expect to model it, especially in a Hispanic Serving Institution (HSI). Faculty who develop critical consciousness through auto-ethnography can facilitate the use of auto-ethnography as a form of personal/professional development with his/her pre-service leaders/educators. 相似文献

We present a proposal for helping students to cope with statistical word problems related to the classification of different cases of confidence intervals. The proposal promotes an environment where students can explicitly discuss the reasons underlying their classification of cases. 相似文献

This study was undertaken in an effort to help illuminate the deleterious effects of traumatic stress on children and families in Mexico. Rates of exposure to traumatic events, family and community violence, and posttraumatic stress disorder (PTSD) were investigated in 87 school-age children and their mothers. Binary logistic regression analysis was performed to examine potential family and ecological risk factors for the presence of child PTSD. A total of 51 children (58.6%) reported an event that met the DSM-IV A criteria, and 36 children (41.4%; 20 boys and 16 girls) met criteria for full PTSD. Traumatic exposure in this sample was considerable, particularly intense, and chronic as a result of interpersonal violence in the home and community. Results support the need for preventive systemic interventions targeting the individual level, parent–child dyadic level, and the larger cultural and community context. 相似文献
