Acquiring an attacking forehand drive: the effects of static and dynamic environmental conditions

Two groups of 10 novice subjects each were trained to perform attacking forehand drives in table tennis and land the balls as fast and as accurately as possible onto a target on the opposite side of the net under two different training conditions. Under the static training condition, the balls were to be struck from a constant position, and under the dynamic training condition, balls approached the subjects in a normal way. Both groups were tested under dynamic conditions prior to and after four days of training, during which they received 1,600 practice trials. Both groups of subjects were shown to increase the number of balls that landed on the target, and learning was also evident from an increased consistency of the direction of travel of the bat at the moment of ball/bat contact. However, no increase in consistency was found for the location of the bat at the moment of ball/bat contact and for the movement times. Thus, learning can occur in the absence of externally generated time-to-contact information, but this is not due to the establishment of a consistent movement form. Learning appears to progress from control at the moment of ball/bat contact backward, toward the moment of initiation.     

What Do We Really Know About the edTPA? Research,PACT, and Packaging a Local Teacher Performance Assessment for National Use

This article calls attention to the overreliance on research about the Performance Assessment for California Teachers (PACT)—often labeled edTPA's predecessor—as justification for the edTPA. The article argues that the distinctions between the assessments are too vast to rely on PACT data to support the edTPA, given the localized nature of PACT and the way in which it is scored.     

Evidence‐Based Interventions for Depressed Mothers and Their Young Children

Depression in mothers is a significant risk factor for the development of maladjustment in children. This article focuses on modifiable risk processes linking depression in mothers and adaptation in their young children (i.e., infancy through preschool age). First, the authors present evidence of the efficacy of interventions for reducing the primary source of risk: maternal depression. Second, they describe a central mechanism—parenting behaviors—underlying the relation between maternal depression and children's adjustment. Third, the authors recommend two different integrated interventions that successfully treat mothers’ depression and enhance parenting skills with infants and young children. Finally, the authors note the possible need for supplementary interventions to address severity and comorbidity of mothers’ depression, barriers to engaging in treatment, and the sustainability of program benefits.     

Eliciting Mathematics Interest: New Directions for Context Personalization and Example Choice

Building on common assumptions in theories of interest and mathematics education, this experimental study examined the effect of context personalization based on individual preferences, group personalization, and example choice with preselected popular examples on middle school students' situational interest and performance in mathematics. Participants (N = 713) learned a principle in probability calculus in one of four instructional conditions. Individual interest and perceived competence were examined as moderators on triggered and maintained situational interest, perceived value, task effort, and performance. Results showed that example choice triggered situational interest in the learning activity and that context personalization influenced perceived value and effort, contingent on students' perceived competence and individual interest in mathematics. We discuss results in relation to previous findings on interest-based interventions and the theoretical and practical implications.
