Student perceptions and instructional effectiveness of deaf and hearing teachers

The study examined the views of deaf and hard of hearing secondary-level students when asked about their preferences for deaf vs. hearing teachers. It also compared elementary- and secondary-level students' achievement scores based on the hearing status of their teachers. Deaf and hard of hearing secondary-level students showed greater preference for deaf teachers, with deaf students showing greater preference for deaf teachers than hard of hearing students did. No significant differences were found in the achievement levels of students based on differences in teacher hearing status. The study supports the limited research done in the past.     

Onset,development, and prevention of drinking and driving among adolescents

An etiological study was designed to investigate the onset and development of drinking and driving among adolescents who recently received their driver’s license. A theoretical framework, derived from Problem Behavior Theory, was applied in order to identify environmental, personality and behavioral factors associated with drinking and driving. Among students who reported that they had driven a motor vehicle in the past three months (N=1416), 33 percent of the males and 22 percent of the females (who averaged 16.7 years) reported “drinking at least two drinks on a single occasion prior to driving” at least once in the previous three months. Personality factors (including perceived ability to drive after drinking, tolerance of drinking and driving, and lack of self-confidence in avoiding drinking and driving situations), perceived environmental factors (perceived car availability and friends modelling of drinking and driving) and behavioral factors (riding with a drinking driver and marijuana use) accounted for a large proportion (49%) of the variance in reported drinking and driving. It is recommended that school-based, peer-led educational programs be designed which target young adolescents prior to the age at which legal driver license is obtained. The programs should be broad-based and consider drinking and driving within the larger context of drinking and driving related behaviors and traffic safety in general.     

Response Time Adjustment in the Stop Signal Task: Development in Children and Adolescents

Adjusting speed to maintain fast and accurate performance is critical to goal-directed behavior. This study examined development of response time adjustments in the stop signal task in 13,709 individuals aged 6–17 years (49.0% Caucasian) across four trial types: correct and incorrect go, successful (stop-inhibit), and failed (stop-respond) trials. People sped more after correct than incorrect go responses and slowed more after failed than successful stop trials. Greater slowing after stop-respond but less slowing after stop-inhibit trials was associated with better response inhibition. Response time adjustments were evident in children as young as age 6, developed throughout childhood, and plateaued by age 10. Results were consistent with the predictions of the error detection and shifting goal priority hypotheses for adjustments.

Precursors of mnemonic strategies in very young children's memory

In 4 studies with 18-24-month-old children, evidence was obtained of strategy-like behaviors in a memory-for-location task in which the child had to remember in what natural location a toy had been hidden. The children exhibited behaviors that resemble the mature strategies of rehearsal and monitoring, including talking about the toy or its hiding place and looking or pointing at it during the delay interval. In Experiments 1 and 2, these strategy-like behaviors were engaged in differentially as a function of familiarity, both of the setting in which the task was embedded and of the task itself. Significantly more target behaviors occurred in an unfamiliar than in a familiar setting, and more target behaviors occurred on the first than on the second day of observation. In Experiment 3, when the basic memory task was modified to remove the memory demands from the child, very few of the strategy-like behaviors occurred, indicating that they were indeed memory specific. In the fourth experiment, the rehearsal-like behaviors were shown to be related to subsequent retrieval. We interpret these results as evidence of an early natural propensity to keep alive what must be remembered, a rudimentary and imperfect version of what will later become more elaborate and planful mnemonic strategies.     

Escape rooms as tools for climate change education: an exploration of initiatives

Abstract

In the last years we have observed a growing interest in the use of gamification approaches for climate change education. While most practices are related to digital gaming, there is a new trend which is still academically unexplored: escape rooms. The main objective of this paper is to serve as an initial exploratory study in this field by identifying and analysing climate change-related escape rooms. For that purpose we carried out a web search and a qualitative content analysis. A total of 17 initiatives are described and compared, unravelling their main audience, country of origin, topics, scenarios and objectives covered. The paper also highlights what escape rooms can offer to climate change education: experiential and immersive learning, problem solving and critical thinking skills, and a sense of collaboration and urgency.     

Historicizing Mathematics and Mathematizing Social Studies for Social Justice: A Call for Integration

Researchers and theorists in education have offered persuasive arguments and evidence documenting the need for, and benefits of, education for social justice. Despite these efforts the intersection of social justice with interdisciplinary curricular designs remains underexplored. This article argues that social justice education is enriched through interdisciplinary curricula, in that it holds the potential for students to develop deeper conceptions of social justice and experience deeper learning outcomes related to content knowledge across subject matter areas. Central to this argument is the notion that situating disciplinary relationships explicitly within social justice perspectives encourages an emphasis on broader and richer sociopolitical consciousness among learners. We draw on historical and contemporary narratives to position social justice in mathematics and social studies education. As researchers in these two fields, we envision greater possibilities for the advancement of knowledge, and we envision learning from inequalities and resisting oppression by nurturing deeper, more explicit connections between mathematics and social studies. We conclude this article with three overviews of learning segments as potential representations of interdisciplinary mathematics-social studies for social justice work in secondary school contexts.     

Extended Validation of the Korean Version of the Quality of Life Survey

In this study, we examined the factor structure and reliability of the Korean Quality of Life (KQoL) survey and compared the KQoL survey to both the World Health Organization Quality of Life-Brief Version (WHOQOL-BREF) and the Satisfaction with Life Scale (SWLS). We also assessed associations between KQoL scores and physical activity (PA) participation. Participants were 557 (male = 281, female = 276) healthy Korean adults with ages between 18 and 71 years (M = 33.2, SD = 14.2). Results of confirmatory factor analyses confirmed the 7-subscale model and indicated acceptable values supporting convergent validity (χ² = 1,678.758, df = 443, p < .001, RMSR = .045, RMSEA = .071, TLI = .880, CFI = .892). Correlations of KQoL subscales with similar subscales of WHOQOL-BREF and with SWLS supported concurrent validity. Results confirm that the KQoL survey can assess multidimensional aspects of quality of life (QoL), including spiritual, physical, social, and psychological. KQoL scores were positively related to PA participation, in line with previous research supporting the positive association of PA with QoL.
