Fostering Supportive Teacher–Child Relationships: Intervention Implementation in a State-Funded Preschool Program

Research Findings: Banking Time is a set of techniques designed to promote positive, supportive relationships through 1-on-1 interactions between teachers and children. Web-based training resources were made available to 252 preschool teachers who received different levels of support as a component of a professional development intervention, and the purpose of this study was to examine teachers' implementation of Banking Time. Teachers with greater levels of professional development support were more likely to implement Banking Time with children in their classes. Teachers were more likely to choose to implement Banking Time with children who had lower social-emotional skills (e.g., more problem behaviors). Teachers developed greater relational closeness with children who participated in Banking Time than with children who did not participate. Practice or Policy: The implications of these preliminary findings for fostering supportive teacher–child relationships are discussed.     

The effects of various mastery criteria on student performance and attitude in a mastery-oriented course

The purpose of this study was to determine the effects of various mastery criteria on student performance and attitude in a course in which mastery learning strategies were employed. Undergraduates in an introductory course in educational psychology were randomly assigned to one of three treatments—one in which mastery criteria gradually increased from 70% to 90%, a second in which mastery criteria gradually decreased from 90% to 70%, or a third in which mastery criteria remained constant at 80%. Results indicated that although the high mastery criterion (90%) had a positive effect on some aspects of quiz performance, it did not have an effect on final examination performance. Results also indicated that students preferred that mastery criteria remain constant during a semester. These findings, when examined in light of previous research, call into question some prior notions regarding the levels at which mastery criteria should be set.     

The effects of ascending,descending, and fixed criteria on student performance and attitude in a mastery-oriented course

This study examined whether the criteria for mastering unit quizzes in a mastery-oriented course should increase, decrease, or remain fixed across units. Subjects were randomly assigned to one of three treatments, one in which mastery criteria on unit quizzes gradually increased, a second in which mastery criteria gradually decreased, and a third in which mastery criteria remained fixed. Results indicated that students in the fixed criterion condition proceeded through the course at the steadiest pace and performed better than the other students on the unit quizzes they mastered. In addition, the vast majority of subjects indicated that they preferred the fixed criterion condition. These results strengthen the notion that the level of performance expected of students in a mastery-oriented course should not vary across units.     

人是如何学习的--兼谈技术在学习中的作用

在去年春天的教育大会中,我参加了一次有关教学技术在转变学校的教与学中的潜力的讨论。其中有一个发言人讲述了发生在他14岁儿子身上的故事。儿子跟他一样,对教育技术的新鲜玩艺非常钟情,并总是希望拥有即将在市面上流行的最新和最先进的技术产品。有一天,儿子将一个电视机遥控     

Researcher Development of Doctoral Students: Supports and Barriers Across Time

We used content analysis to analyze 42 counseling doctoral students' reports of supports and barriers influencing their researcher development across 3 years. In line with social cognitive career theory, the students named cognitive-person, environmental, and social-context influences. Analyses indicated no differences in frequencies of supports and barriers across time but significant differences by cohort.     

Kinetic and kinematic analysis of stamping impacts during simulated rucking in rugby union

Laceration injuries account for up to 23% of injuries in rugby union. They are frequently caused by studded footwear as a result of a player stamping onto another player during the ruck. Little is known about the kinetics and kinematics of rugby stamping impacts; current test methods assessing laceration injury risk of stud designs therefore lack informed test parameters. In this study, twelve participants stamped on an anthropomorphic test device in a one-on-one simulated ruck setting. Velocity and inclination angle of the foot prior to impact was determined from high-speed video footage. Total stamping force and individual stud force were measured using pressure sensors. Mean foot inbound velocity was 4.3 m ? s^?1 (range 2.1–6.3 m ? s^?1). Mean peak total force was 1246 N and mean peak stud force was 214 N. The total mean effective mass during stamping was 6.6 kg (range: 1.6–13.5 kg) and stud effective mass was 1.2 kg (range: 0.5–2.9 kg). These results provide representative test parameters for mechanical test devices designed to assess laceration injury risk of studded footwear for rugby union.     

Making it happen: Possibilities and pitfalls of Cunningham's educational semiotic

In fundamental agreement with Cunningham's overall thesis, we attempt in this paper to articulate what an educational semiotic might look like on a practical level. For educational psychologists, it should mean an increased awareness of the limited, localized world views offered by current models of cognition and an increased attentiveness to alternate models. For teachers, an educational semiotic offers integration of cognition and affect and instructional strategies that depend upon and facilitate many ways of knowing. For an educational semiotic to be realized, however, there must be much greater attention paid to the roles of motivation and metacognition in semiotic pedagogy.     

Dominance relationships in femaleHerotilapia multispinosa (Pisces: Cichlidae)

Agonistic interactions between all possible pairings of 10 adult female rainbow cichlids (Herotilapia multispinosa) were observed in three round-robin tournaments. Specific behaviors and color patterns were found to characterize winning and losing fish. The outcomes of agonistic encounters were used to construct a hypothetical dominance hierarchy. This hierarchy was consistent over the three tournaments in that (1) the order of animals in the hierarchy remained relatively unchanged and (2) the relationship between the members of a particular dyad tended to remain stable. The latter was especially true for fish of widely different dominance rank.
