Task Level

Purpose The purpose of this systematic review was to determine evidence of a cognate effect for young multilingual children (ages 3;0–8;11 [years;months], preschool to second grade) in terms of task-level and child-level factors that may influence cognate performance. Cognates are pairs of vocabulary words that share meaning with similar phonology and/or orthography in more than one language, such as rose – rosa (English–Spanish) or carrot – carotte (English–French). Despite the cognate advantage noted with older bilingual children and bilingual adults, there has been no systematic examination of the cognate research in young multilingual children. Method We conducted searches of multiple electronic databases and hand-searched article bibliographies for studies that examined young multilingual children's performance with cognates based on study inclusion criteria aligned to the research questions. Results The review yielded 16 articles. The majority of the studies (12/16, 75%) demonstrated a positive cognate effect for young multilingual children (measured in higher accuracy, faster reaction times, and doublet translation equivalents on cognates as compared to noncognates). However, not all bilingual children demonstrated a cognate effect. Both task-level factors (cognate definition, type of cognate task, word characteristics) and child-level factors (level of bilingualism, age) appear to influence young bilingual children's performance on cognates. Conclusions Contrary to early 1990s research, current researchers suggest that even young multilingual children may demonstrate sensitivity to cognate vocabulary words. Given the limits in study quality, more high-quality research is needed, particularly to address test validity in cognate assessments, to develop appropriate cognate definitions for children, and to refine word-level features. Only one study included a brief instruction prior to assessment, warranting cognate treatment studies as an area of future need. Supplemental Material https://doi.org/10.23641/asha.12753179

Valid Criterion

In this study we assessed whether the predictive validity of personality scores is stronger when respondent test-taking motivation (TTM) is higher rather than lower. Results from a field sample comprising 269 employees provided evidence for this moderation effect for one trait, Steadfastness. However, for Conscientiousness, valid criterion prediction was only obtained at low levels of TTM. Thus, it appears that TTM relates to the criterion validity of personality testing differently depending on the personality trait assessed. Overall, these and additional findings regarding the nomological net of TTM suggest that it is a unique construct that may have significant implications when personality assessment is used in personnel selection.

Research Goal

This research goal is to identification and evaluation influence of work motivation and work environment to employee’s performance in BAPPEDA Kabupaten Wonosobo. The object of this research is 37 employees of Badan Perencanaan Pembangunan Kabupaten Wonosobo. And the location of this research is at Badan Perencanaan Pembangunan Kabupaten Wonosobo. The analysis used is test validity, reliability testing, and test the hypothesis, with the help of the computer program SPSS version 17, using multiple linear regression analysis. Based on calculations of data and analysis used, the regression equation is obtained: Y = 11.733 + 0.320 X1 +0.334 X2 + ε, by using the equation regression analytical method can conclude that (X1) take effect positively against employees performance. With t value in amount of 2,219 (bigger than t in table in amount of 1,690) and significance value in amount of 0,33. By applying significance limited value in amount of 0,05, it means, hypothesis that claim if work motivation take effect against employees performance can be accepted. There is a positive and significant correlation between work environment variables (X2) against employees. With t value in amount of 2,219 (bigger than t in table in amount of 1,690) and significance value in amount of 0,33 (smaller than 0,5). Simultaneously, work motivation take effect positively and significantly against employees performance with the F value in amount of 11,562 (bigger than 0.05), then obtained significance value 0.000. It can be concluded that the work motivation and work environment has a positive and significant influence on employee performance in BAPPEDA Kabupaten Wonosobo.

The purpose of this research was to find out the effectiveness of the implementation of problem based learning model with multiple representations to reduce the percentage of students’ difficulty in XIth Science SMAN 1 Pontianak. The research design was one group pretest-posttest design, and the instrument used was an essay test. Test reliskill (0, 5) was classified as medium, and test validity (3,56) was classified as a medium. The effect size of this research (2,18) was classified high, but the reduction percentage of the student’s difficulty (41,33%) was classified as a medium. The percentage increase in the students’ skill in multiple representations (52,38%) was classified as a medium. The research doesn’t find a significant correlation between the posttest result of students’ difficulty and the posttest result of studentS’ skill in multiple representations (C = 0,935, p = 0.348). The research result was expected to the development of the implementation problem based learning model with multiple representations approach.Keywords: Implementation, Multiple representations, Problem Based Learning

Abstract Surveys based on self-reported hygiene-relevant routine behaviors have played a crucial role in policy responses to the COVID-19 pandemic. In this article, using anchoring to test validity in a randomized controlled survey experiment during the COVID-19 pandemic, we demonstrate that asking people to self-report on the frequency of routine behaviors are prone to significant measurement error and systematic bias. Specifically, we find that participants across age, gender, and political allegiance report higher (lower) frequencies of COVID-19-relevant behaviors when provided with a higher (lower) anchor. The results confirm that such self-reports should not be regarded as behavioral data and should primarily be used to inform policy decisions if better alternatives are not available. To this end, we discuss the use of anchoring as a validity test relative to self-reported behaviors as well as viable alternatives to self-reports when seeking to behaviorally inform policy decisions.

While interpersonal skills in telehealth may positively impact clinical practice, patient engagement and outcomes, assessment strategies are lacking. We conducted a multi-stage iterative approach to develop and test validity and reliability of the Teaching Interpersonal Skills in Telehealth checklist (TIPS-TC). First, we identified observable communication behaviors from the literature. Second, we surveyed telehealth managers and researchers (N = 11) to rate appropriateness of potential checklist items. Level of agreement (35%–91%) and Kappa statistic (0.18–0.89) confirmed items to be retained and identified items to modify. Based on response patterns and comments, we reduced 44 items to 12 critical checklist behaviors. Third, student clinicians used the checklist with video telehealth consultations and provided feedback. Fourth, we conducted reliability testing with practitioners and administrators (N = 68) who completed the TIPS-TC for two versions of a telehealth scenario. Strong interrater reliability intraclass correlation coefficient (ICC) and test-retest reliability ICC (both p < .001), along with non-significant findings of order effects supported the checklist as an acceptable instrument to differentiate high skill from low skill telehealth sessions. The TIPS-TC offers an evidence-based approach to assessing interpersonal skills in telehealth to help evaluate clinician competence and tailor learning activities across disciplinary roles.
