Combining a human performance model and a Six Sigma model to assess performance in a military environment

Military officials continually search for improvements in processes that focus on high‐performance outcomes. This qualitative study investigated process improvements of two departments within the Naval Diving and Salvage Training Center (the Security Department and the Testing Department) by assessing performance levels of the two departments using a combinatorial model from human performance theory and Six Sigma theory. Study findings produced strong empirical evidence with specific recommendations for initiating cost‐effective interventions for improvements. The Behavior Engineering Model was used to identify possible solutions to post‐training performance gaps identified during the evaluation.     

Symbolic,identity, and probe delayed matching of sounds by the bottlenosed dolphin

The short-term memory for sounds of the bottlenosed dolphin was tested using symbolic, identity, and probe forms of the delayed matching-to-sample (DMS) task. The forms differed in the number (one or two) or nature (symbolic or identity matches of sample sounds) of postdelay test stimuli available as memory retrieval cues. Although symbolic DMS was difficult to learn, the final performance level was approximately equal to that for identity or probe DMS. On all tasks, the dolphin’s responses were above 80% correct through to delays of 90 sec and, in some cases, through to delays of 180 and 240 sec, the “limits” being governed mainly by the dolphin’s reluctance to continue being tested at long delays. Encoding of sample stimuli into their learned symbolic representation was hypothesized to have reduced symbolic DMS to a recognition memory task, resulting in the observed equivalence of performance with the other two recognition memory tasks. The probe DMS results, unlike those for identity or symbolic DMS, showed no significant proactive interference effects from samples of prior trials. Instead, proactive interference was traceable to the probe value of the prior trial. Overall, the auditory DMS data for the dolphin were functionally similar to results reported for monkeys tested on symbolic, identity, and probe visual DMS tasks.     

Pre-kindergarten teachers’ use of transition practices and children's adjustment to kindergarten

This study describes pre-kindergarten teachers’ use of kindergarten transition practices and examined the extent to which these practices were associated with kindergarten teachers’ judgments of children's social, self-regulatory, and academic skills upon their entry into kindergarten. Participants were 722 children from 214 pre-kindergarten classrooms participating in the National Center for Early Development and Learning's (NCEDL) Multi-State Pre-kindergarten Study. Of nine transition practices intended to promote children's adaptation to kindergarten, pre-kindergarten teachers reported implementing, on average, six transition practices, with notable variation across pre-kindergarten classrooms. Children were judged by their kindergarten teachers to have more positive social competencies and fewer problem behaviors when they attended pre-kindergarten classrooms in which more transition activities were implemented and, specifically, in which teachers discussed curricula or specific children with kindergarten teachers. In addition, positive associations between kindergarten teachers’ perceptions of children's social competence and pre-kindergarten transition activities (total number of activities and activities that children experience directly) were stronger for children who experienced social and economic risks. Implications of these findings related to alignment across the pre-kindergarten to kindergarten settings to improve children's school readiness are discussed.     

The ‘good’ parent in relation to early childhood literacy: symbolic terrain and lived practice

In this paper we consider the place of early childhood literacy in the discursive construction of the identity(ies) of ‘proper’ parents. Our analysis crosses between representations of parenting in texts produced by commercial and government/public institutional interests and the self‐representations of individual parents in interviews with the researchers. The argument is made that there are commonalities and disjunctures in represented and lived parenting identities as they relate to early literacy. In commercial texts that advertise educational and other products, parents are largely absent from representations and the parent's position is one of consumer on behalf of the child. In government‐sanctioned texts, parents are very much present and are positioned as both learners about and important facilitators of early learning when they ‘interact’ with their children around language and books. The problem for which both, in their different ways, offer a solution is the “not‐yet‐ready” child precipitated into the evaluative environment of school without the initial competence seen as necessary to avoid falling behind right from the start. Both kinds of producers promise a smooth induction of children into mainstream literacy and learning practices if the ‘good parent’ plays her/his part. Finally, we use two parent cases to illustrate how parents' lived practice involves multiple discursive practices and identities as they manage young children's literacy and learning in family contexts in which they also need to negotiate relations with their partners and with paid and domestic work.     

Effects of Methylphenidate on Academic Achievement from First to Second Grade

The objectives of the current study were to identify the long‐term effects of Methylphenidate (Ritalin) on cognitive ability and academic achievement. A retrospective/longitudinal design was utilised in the study with dependent measures being scores from the Iowa Tests of Basic Skills (ITBS). The study included 17 experimental subjects who were identified with ADHD and placed on Methylphenidate between first and second grade. For each experimental child, a control child without ADHD was matched based on gender, Verbal IQ score, and family structure. Results of the study revealed that the Methylphenidate group's achievement was lower both before and after medication even after being matched on verbal abilities. The results also indicated that after receiving medication the Methylphenidate group's rate of learning was similar to the Control groups on Reading, Word Analysis, Listening, Vocabulary, and overall achievement. Finally, a positive relationship between dosage level and Listening subtest scores was observed while a negative relationship was obtained between dosage level and Vocabulary subtest scores.     

Communicating Prevention: The Effects of the keepin' it REAL Classroom Videotapes and Televised PSAs on Middle-School Students' Substance Use

This study sought to determine if exposure to two communication-oriented activities, videotapes and public service announcements, accounts for changes in substance use among adolescents participating in the Drug Resistance Strategies Project's keepin' it REAL adolescent substance use prevention curriculum. Middle-school students (4,734, 72% Latino) responded to questionnaires related to these analyses. An analysis of covariance (ANCOVA) model was fit separately to six substance use outcomes. The results suggested that intervention students who saw four or five videos engaged in less substance use in the past month than did students who saw fewer videos. Having seen the PSAs one or more times did not predict the reported change in substance use.     

Looking for love in all the wrong places: Accessing sexual and reproductive health information via the Readers' Guide to Periodical Literature

The Readers' Guide to Periodical Literature has been described as a cultural barometer. It supports scholars of history and culture by providing access to ideas circulated via the mass media in earlier times, but its own coverage and indexing practices also reveal attitudes and values toward issues of the time. The Progressive Era (1900–1924) coincides with the founding and growth of the Readers' Guide. Examining how the Readers' Guide directed readers' attention to matters of sexual and reproductive health in its first quarter century demonstrates changes in social attitudes and has implications for scholarly work. The array of index terms required to locate information on this topic indicates both barriers to information access for contemporary readers as well as challenges for present-day scholars concerned with recovering information of the era.     

Effects of student-facilitated learning on instructional facilitators

We investigated perceptions about learning strategy use and instructional roles among a sample of high needs adolescents (n = 230) who acted as near-peer instructional facilitators. The sample was drawn from science and mathematics classes in nonselective public secondary schools in New York City. Students participated in an inschool intervention that draws on social constructivism, theory and research on metacognition and learning strategies, role theory, and empirical findings from the peer-to-peer learning literature to promote advanced achievement among students who act as facilitators. Using a pre- and post-test single group design, we surveyed student instructional facilitators before and after program participation and related their perceptions about learning strategy use and perceptions about teaching roles to data about academic achievement. We found no survey gains in student perceptions about learning strategies or instructional roles between pre-survey (fall) and post-survey (spring). We found small but significant effects of individual perceptions about learning strategies and teaching roles on academic gains among instructional facilitators. The study also suggests that an in-school near-peer facilitated learning program can be an effective means to raise achievement in urban high schools. The study provides partial support for theories that hold that metacognition and role perceptions are involved in the academic gains of instructional facilitators, as gains in these dimensions were small compared to achievement gains.
