Efforts to improve science education include university science departments hiring Science Faculty with Education Specialties (SFES), scientists who take on specialized roles in science education within their discipline. Although these positions have existed for decades and may be growing more common, few reports have investigated the SFES approach to improving science education. We present comprehensive data on the SFES in the California State University (CSU) system, the largest university system in the United States. We found that CSU SFES were engaged in three key arenas including K-12 science education, undergraduate science education, and discipline-based science education research. As such, CSU SFES appeared to be well-positioned to have an impact on science education from within science departments. However, there appeared to be a lack of clarity and agreement about the purpose of these SFES positions. In addition, formal training in science education among CSU SFES was limited. Although over 75% of CSU SFES were fulfilled by their teaching, scholarship, and service, our results revealed that almost 40% of CSU SFES were seriously considering leaving their positions. Our data suggest that science departments would likely benefit from explicit discussions about the role of SFES and strategies for supporting their professional activities.  相似文献

This systematic review and meta-analysis considered evidence of guided play compared to direct instruction or free play to support children's learning and development. Interventions from 39 studies were reviewed (published 1977–2020); 17 were included in meta-analysis (Ntotal = 3893; Mchildage = 1–8 years; Mgirls 49.8%; Methnicity White 41%, African American/Black 28%, Hispanic 19%). Guided play had a greater positive effect than direct instruction on early maths skills (g = 0.24), shape knowledge (g = 0.63), and task switching (g = 0.40); and than free play on spatial vocabulary (g = 0.93). Differences were not identified for other key outcomes. Narrative synthesis highlighted heterogeneity in the conceptualization and implementation of guided play across studies.  相似文献

Using four waves of longitudinal data collected in 2015–2019 from 1419 Dutch adolescents (Mage = 12.5, 45.9% female, 21.9% immigrant), this study identified trajectories of problematic social media use (SMU) in parallel with trajectories of SMU frequency. Latent class growth analysis identified two subgroups with relatively high levels of problematic SMU over time: One showed high (24.7%) and one showed average SMU frequency (15.8%). Also, two subgroups with persistently low levels of problematic SMU were identified: One reported low (22.4%) and one reported high SMU frequency (37.1%). Although both subgroups with high levels of problematic SMU reported low subjective well-being, the group with high SMU frequency showed low self-control, whereas the group with average SMU frequency reported poor social competencies.  相似文献

Using quantitative content analysis, we examined the prevalence and use of the Multicultural Social Justice Counseling Competencies (MSJCC) in 21 ACA journals between June 2015 and July 2021. We found that only 7.62% of the articles (n = 2860) referenced the MSJCC. Implications for counselor educators are discussed.  相似文献

We present a case example of a school leader whose understanding of both in- and out-of-school policies and issues supported 2 students who experienced severe trauma. We describe some of the principal's key beliefs and practices that led to the development of a justice-oriented school, and then contextualize her work in a “social frontiers” perspective. We conclude by suggesting that, especially in contexts where poverty affects many students, school leaders must go beyond school walls to cultivate appropriately responsive systems of practice that allow all students to thrive.  相似文献

This article studies the conceptions of the interior of the Earth held by Portuguese elementary school children and senior citizens. Several studies were conducted regarding conceptions related to Earth sciences, such as rocks, minerals, earthquakes geological time, and Earth structure. Most of these studies involved students enrolled in compulsory education, some involved higher education students, several involved teachers, and only a few involved adults. The majority of the results showed that many misconceptions are held by people of all ages. Similar results were found in this study, as both children and senior citizens revealed several misconceptions. The research resorted to a questionnaire based on a drawing task so as to find out the way that children and senior citizens imagine the structure and composition of the interior of our planet. A comparison between children’s and senior citizens’ drawings was made, as well as a comparison between those drawings and the historical models of the internal structure of the Earth. We found that only a small number of children and even a smaller number of senior citizens recognize that the interior of the Earth is organized in concentric layers. They assume that soil and water are a common part of the internal composition of our planet. Similarities between the drawings and the historical models were identified, particularly similarities related to Gautier’s model, which accepts the possibility of the existence of life in the interior of the planet as it happens on its surface.  相似文献
