Mesleki Gelişim Programı: Öğretmenlerin Bilimin Doğasını Öğrenme ve Öğretme İnançları
The Nature of Science (NOS) is an important component of science literacy, which is the main vision of science teaching programs. In contrast, science teachers face significant problems in transferring the nature of science to classroom practices. Science teachers' classroom practices are influenced by their belief in learning and teaching. Therefore, the development of teachers' beliefs in learning and teaching the NOS is important for the development of classroom practices. Thus, in this research, the effect of a continuing professional development (CPD) program aimed at improving science teachers’ professional competences related to the NOS on their beliefs about learning and teaching of the NOS was searched. 18 volunteered science teachers participated in the research. A single group pretest-posttest experimental design was used in the study. The data were collected using the ‘’Beliefs About Reformed Science Teaching and Learning (BARSTL)’’developed by Sampson and Benton (2006) and the ‘’Scale of Self-Efficacy Belief About Teaching the Nature of Science’’ developed by researchers. Pre-test and post-test performances of the teachers were compared using the Wilcoxon test. As a result of the research, it has been shown that the CPD program is effective in developing teachers' self-efficacy beliefs about teaching the NOS and teachers’ beliefs for reform approaches. Findings show that science teachers' self-efficacy beliefs are quite high, even though their views on the nature of science are inadequate before the professional development program. There is a risk that teachers who have inadequate views and misconceptions about NOS but who are eager to teach and who have high self-efficacy will be an obstacle to the education of science literate individuals. This has further clarified the need for CPD programs that will enable them to face current misconceptions and support their classroom practices, without compromising teachers' enthusiasm and self-efficacy about NOS that is important component of scientific literacy. For this reason, it has been proposed to increase the number of such professional development programs in accordance with the changing professional development paradigms.Bilimin doğası, fen öğretim programlarının ana vizyonu olan bilim okuryazarlığının önemli bir bileşenidir. Buna karşılık fen bilgisi öğretmenleri bilimin doğasını sınıf içi uygulamalarına transfer etmekte önemli sorunlarla karşılaşmaktadır. Fen bilgisi öğretmenlerinin sınıf içi uygulamaları öğrenme ve öğretmeye yönelik sahip oldukları inançlardan etkilenmektedir. Dolayısıyla öğretmenlerin bilimin doğasını öğrenme ve öğretme inançlarının gelişimi, sınıf içi uygulamalarının geliştirilmesi açısından önemlidir. Bu araştırmada fen bilgisi öğretmenlerinin bilimin doğası ile ilgili mesleki yeterliliklerini geliştirmeyi amaçlayan uzun süreli bir mesleki gelişim programının öğretmenlerin bilimin doğasını öğrenme ve öğretme inançları üzerindeki etkisi araştırılmıştır. Araştırma gönüllü 18 fen bilgisi öğretmeni ile gerçekleştirilmiştir. Araştırmada tek gruplu ön test-son test deneysel desen kullanılmıştır. Veriler Sampson ve Benton (2006) tarafından geliştirilen Reform Yaklaşımlarına Yönelik İnançlar Ölçeği (BARSTL) ve araştırmacılar tarafından geliştirilen Bilimin Doğasının Öğretimi Özyeterlik Ölçeği ile toplanmıştır. Öğretmenlerin ön test ve son test performansları Wilcoxon Testi kullanılarak karşılaştırılmıştır. Araştırmadan elde edilen bulgular uzun süreli mesleki gelişim programının öğretmenlerin bilimin doğasını öğretmeye yönelik öz yeterlilik inançlarını ve reform yaklaşımlarına yönelik inançlarını geliştirdiğini göstermiştir. Bulgular, fen bilgisi öğretmenlerinin mesleki gelişim programı öncesinde bilimin doğası hakkında görüşlerinin yetersiz düzeyde olmasına rağmen öz yeterlik inançlarının oldukça yüksek olduğunu ortaya koymuştur. Bilimin doğası hakkında yetersiz görüş ve çeşitli kavram yanılgılarına sahip ancak bu konuyu öğretmeye hevesli ve öz yeterliği yüksek olan öğretmenlerin, bilim okur yazarı bireyler yetiştirilmesinin önünde engel teşkil etme riski bulunmaktadır. Bu durum, bilim okuryazarlığının önemli bir bileşeni olan bilimin doğası hakkında öğretmenlerin heveslerini ve öz yeterliliklerini düşürmeden, mevcut kavram yanılgılarıyla yüzleşmelerini sağlayacak ve onların sınıf içi uygulamalarını destekleyecek uzun süreli mesleki gelişim programlarına ihtiyacı daha da belirginleştirmiştir. Bu nedenle bu araştırmada değişen mesleki gelişim paradigmalarına uygun bu tür mesleki gelişim programlarının arttırılması önerilmiştir
A new index for the prediction of in-hospital mortality in patients with acute pulmonary embolism: The modified shock index
BACKGROUND: Pulmonary embolism severity index, its simplified version, and shock index have been used for risk stratification in acute pulmonary embolism. In this study, we proposed a modification in severity index and evaluated the correlates and prognostic value of modification in severity index in this setting. METHODS: The study group comprised retrospectively evaluated 181 patients with acute pulmonary embolism. Systematic workup including pulmonary embolism severity index, its simplified version, shock index, biomarkers, and echocardiographic and multidetector computed tomography assessments was performed in all patients. Moreover, we calculated modification in severity index by multiplying original shock index (heart rate/systolic blood pressure ratio) and a third component, 1/pulse oxymetric saturation (pSat O2%) ratio. The primary endpoint was defined as all-cause mortality and hemodynamic collapse during the hospital stay. RESULTS: On the basis of initial risk stratification, ultrasound-assisted thrombolysis, systemic tissue-type plasminogen activator, and unfractionated heparin therapies were utilized in 83 (45.9%), 37 (20.4%), and 61 (33.7%) patients, respectively. The primary end-point occurred in 13 (7.2%) patients. Receiver-operating curve analysis revealed that modification in severity index had the highest area under the curve of 0.739 (0.588-0.890, P =.002) compared with shock index, pulmonary embolism severity index, or its simplified version. The modification in severity index > 0.989 predicted primary endpoint with 73% sensitivity and 54% specificity. CONCLUSIONS: The modification in severity index seems to be a simple, quick, and compre-hensive risk assessment tool for bedside evaluation at initial stratification, in monitoring the clinical benefit from therapies, and decision-making for escalation to other reperfusion strategies in patients with acute pulmonary embolism. However, the prognostic value of modification in severity index needs to be validated with further studies
A novel composed index to evaluate the right ventricle free-wall adaptation against ventricular wall stress in acute pulmonary embolism
Background: Pulmonary embolism severity index and simplified pulmonary embolism severity index have been utilized in initial risk evaluation in patients with acute pulmonary embolism. However, these models do not include any imaging measure of right ventricle function. In this study, we proposed a novel index and aimed to evaluate the clinical impact. Methods: Our study population comprised retrospectively evaluated 502 patients with acute pulmonary embolism managed with different treatment modalities. Echocardiographic and computed tomographic pulmonary angiography evaluations were performed at admission to the emergency room within maximally 30 minutes. The formula of our index was as follows: (right ventricle diameter × systolic pulmonary arterial pressure-echo)/(right ventricle free-wall diameter × tricuspid annular plane systolic excursion). Results: This index value showed significant correlations to clinical and hemodynamic severity measures. Only pulmonary embolism severity index, but not our index value, independently predicted in-hospital mortality. However, an index value higher than 17.8 predicted the long-term mortality with a sensitivity of 70% and specificity of 40% (areas under the curve = 0.652, 95% CI, 0.557-0.747, P = .001). According to the adjusted variable plot, the risk of long-term mortality increased until an index level of 30 but remained unchanged thereafter. The cumulative hazard curve also showed a higher mortality with high-index value versus low-index value. Conclusions: Our index composed from measures of computed tomographic pulmonary angiography and transthoracic echocardiography may provide important insights regarding the adaptation status of right ventricle against pressure/wall stress in acute pulmonary embolism, and a higher value seems to be associated with severity of the clinical and hemodynamic status and long-term mortality but not with in-hospital mortality. However, the pulmonary embolism severity index remained as the only independent predictor for in-hospital mortality
Parental psychological distress associated with COVID-19 outbreak: A large-scale multicenter survey from Turkey
Aims: Pandemics can cause substantial psychological distress; however, we do not know the impact of the COVID-19 related lockdown and mental health burden on the parents of school age children. We aimed to comparatively examine the COVID-19 related the stress and psychological burden of the parents with different occupational, locational, and mental health status related backgrounds. Methods: A large-scale multicenter online survey was completed by the parents (n = 3,278) of children aged 6 to 18 years, parents with different occupational (health care workers—HCW [18.2%] vs. others), geographical (İstanbul [38.2%] vs. others), and psychiatric (child with a mental disorder [37.8%]) backgrounds. Results: Multivariable logistic regression analysis showed that being a HCW parent (odds ratio 1.79, p <.001), a mother (odds ratio 1.67, p <.001), and a younger parent (odds ratio 0.98, p =.012); living with an adult with a chronic physical illness (odds ratio 1.38, p <.001), having an acquaintance diagnosed with COVID-19 (odds ratio 1.22, p =.043), positive psychiatric history (odds ratio 1.29, p <.001), and living with a child with moderate or high emotional distress (odds ratio 1.29, p <.001; vs. odds ratio 2.61, p <.001) were independently associated with significant parental distress. Conclusions: Parents report significant psychological distress associated with COVID-19 pandemic and further research is needed to investigate its wider impact including on the whole family unit. © The Author(s) 2020
A multi-country test of brief reappraisal interventions on emotions during the COVID-19 pandemic.
The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about a situation. Participants from 87 countries and regions (n = 21,644) were randomly assigned to one of two brief reappraisal interventions (reconstrual or repurposing) or one of two control conditions (active or passive). Results revealed that both reappraisal interventions (vesus both control conditions) consistently reduced negative emotions and increased positive emotions across different measures. Reconstrual and repurposing interventions had similar effects. Importantly, planned exploratory analyses indicated that reappraisal interventions did not reduce intentions to practice preventive health behaviours. The findings demonstrate the viability of creating scalable, low-cost interventions for use around the world
