New Frontiers in Visual Search: An Exploratory Study in Live Tennis Situations

This study compares the motor skills and physical fitness of school-age children (6-12 years) with visual impairments (VI; n = 60) and sighted children (n = 60). The relationships between the performance parameters and the children's body composition are investigated as well as the role of the severity of the impairment. The degree of VI did not differentially affect the outcomes. Compared to their sighted peers, the children with VI scored lower on the locomotor and object control skills as assessed with the Test of Gross Motor Development-2, and the physical fitness (Eurofit) parameters of plate tapping, the standing broad jump, the modified 5 × 10-m shuttle run, and 20-m multistage shuttle run (20-MST). Their body mass and body fat indexes were inversely correlated with the standing broad jump and the 20-MST, but positively correlated with handgrip strength. Moreover, significant inverse correlations were found between their locomotor and object control skills on the one hand and plate tapping and the 5 × 10-m shuttle run on the other hand. Given the relatively high proportion (25%) of overweight/obese children within the VI sample, educators are recommended to promote health-related activities and help enhance motor skills in this population.

Maximizing Performance Feedback Effectiveness through Videotape Replay and a Self-Controlled Learning Environment

This study was designed to examine whether participants who could control the schedule of performance feedback (KP) would learn differentially from those who received a rigid feedback schedule while learning a complex task. Participants (N = 48) were randomly assigned to self-controlled KP (SELF), summary KP (SUMMARY), yoked control (YOKE), or knowledge of results only (KR) conditions. Data collection consisted of an acquisition phase and a 4-day retention phase during which right-handed participants performed a left-handed ball throw. Overall, throwing form improved across trial blocks during acquisition, with the SUMMARY, SELF, and YOKE groups showing more improvement than the KR group. During retention, the SELF group retained a higher level of throwing form and accuracy in comparison to the other groups. Results suggest that when given the opportunity to control the feedback environment, learners require relatively less feedback to acquire skills and retain those skills at a level equivalent to or surpassing those who are given more feedback but receive it passively.     

A comparison of preservice and in-service earth and space science teachers' general mental abilities,content knowledge,and problem-solving skills

The purpose of this study was to compare in-service and preservice earth and space science teachers on their general mental abilities, their content knowledge or declarative knowledge of earth and space sciences, the Gagnean levels of their content knowledge or declarative knowledge, and the procedural knowledge used in solving earth and space science problems. This study used a contrast-group design to compare in-service (n = 30) and preservice (n = 30) earth and space science teachers. The in-service earth science teachers (a) bring more declarative knowledge to the problem-solving situation, (b) use fewer steps while problem solving, (c) generate more subroutines and alternate hypotheses, and (d) possess different structural knowledge than do preservice earth science teachers. Findings from this study support Norman's theory of learning that experts (in-service teachers) function at the tuning mode of learning, whereas novices (preservice teachers) function in an accreting or structuring mode. In-service earth science teachers exhibited smoothness, automaticity, and decreased mental effort not exhibited by preservice earth and space science teachers.     

Perceptual Decision Making for Baseball Pitch Recognition: Using P300 Latency and Amplitude to Index Attentional Processing

Abstract

This study was designed to examine the perceptual and attentional processes associated with the effects of administering a cost-benefit precuing paradigm to intermediate and advance-level baseball batters. Psychophysiological and performance data obtained from 10 advanced and 10 intermediate-level players were compared. A total of 400 pitches (200 fastballs, 200 curveballs) was randomly presented via a large projection screen, and participants pressed one of two buttons to indicate the type of pitch thrown. Verbal precues were given for 300 of the pitches. Of those, 75% were valid, and 25% were invalid. Electroencephalographic data collected from the P_z location was used to assess the latency and amplitude of P300. Analysis of variance (Skill Level x Precue x Pitch) for P300 and reaction time (RT) indicated that intermediate batters produced shorter P300 latencies, larger P300 amplitudes, longer RTs, and less correct responses than the advanced batters; the effects were more pronounced for the curveballs. These results suggest that intermediate batters are less efficient in their perceptual decision-making processes due to greater limitations in attentional capacity when compared with advanced batters.     

Young Children’s Mathematical Learning From Intelligent Characters

Children’s math learning (N = 217; M_age = 4.87 years; 63% European American, 96% college-educated families) from an intelligent character game was examined via social meaningfulness (parasocial relationships [PSRs]) and social contingency (parasocial interactions, e.g., math talk). In three studies (data collected in the DC area: 12/2015–10/2017), children’s parasocial relationships and math talk with the intelligent character predicted quicker, more accurate math responses during virtual game play. Children performed better on a math transfer task with physical objects when exposed to an embodied character (Study 2), and when the character used socially contingent replies, which was mediated by math talk (Study 3). Results suggest that children’s parasocial relationships and parasocial interactions with intelligent characters provide new frontiers for 21st century learning.     

A study of culturally syntonic variables in the bilingual/bicultural science classroom

The purpose of this study was to conduct a needs assessment of bilingual/bicultural elementary science classrooms in order to determine if the current instructional environment addresses the educational needs of Hispanic/Latino children. This study examined 57 randomly selected elementary bilingual/bicultural science classrooms in a large metropolitan area of the southwestern United States in terms of culturally syntonic variables (i.e., culture-of-origin beliefs and/or practices that impact the teaching/learning process). Findings from this study indicate that Hispanic/Latino children are receiving science instruction: (a) with culturally asyntonic printed materials, teaching strategies, and supplementary materials, (b) in classrooms that do not use the child's native language, familia learning groups, peer tutoring, or manipulative materials, and (c) with oral and verbal instruction that lack culturally syntonic role models, examples, analogies, and elaborations. Findings from this study imply that changes are needed in pre-service and in-service teacher training, in science textbook formats, and in the scope and focus of elementary school bilingual/bicultural science curriculum and instructional strategies.
