“…In this regard, some engineering education scholars conducted more thorough analyses of students' and teachers' NOE views, revealing that both groups held inadequate views of NOE (Aydoğan & Çakıroğlu, 2021; Karataş et al, 2016). Karatas et al (2011), for example, studied sixth graders' NOE views and focused on students' understanding of the NOE.…”

Background: Pre-college engineering education reform documents aim to help students develop engineering literacy. Helping students develop sophisticated epistemological views about engineering makes a significant contribution toward developing engineering-literate citizenry. Despite these widely recognized benefits, research on students' and teachers' epistemological views about engineering, commonly termed nature of engineering (NOE) views, has remained stagnant due to the absence of an open-ended questionnaire whose collected evidence of validity indicates its appropriateness for assessing students' and teachers' NOE understanding. Purpose: The purpose of this study is threefold: (a) describing the development of a new open-ended instrument, the Views of Nature of Engineering Questionnaire version B (VNOE-B), (b) providing evidence in support of the VNOE-B validity and reliability, and (c) discussing the implications of the newly developed instrument for future research. Design/Method: We aimed to provide evidence for the content and face validity of the VNOE-B by seeking input from a panel of science/engineering educators. Evidence for the construct validity was determined by analyzing the open-ended questionnaire and semistructured interview responses provided by pre-service and in-service teachers (considered novices in this field) and experts (engineers and engineering educators). Results: Our findings indicate that the VNOE-B is consistently successful in differentiating between experts' and novices' NOE views. All engineering experts held sophisticated NOE views across all NOE views under study, whereas most novices held partially informed or uninformed NOE views. Conclusion: Evidence of validity supports the appropriateness of the VNOE-B as an open-ended instrument for assessing adults' NOE views. Its application may guide teacher educators in determining the efficacy of teacher professional development in meeting the aim of improving in-service teachers' NOE

“…Rigid polyurethane foams (RPUFs) are mainly used as thermal insulation materials in various industrial applications such as automotive, transportation, construction, and so forth due to their low‐thermal conductivity coefficients 1–5 . However, the rigid polyurethane foams easily decompose with producing a large amount of small molecular fragments in the gaseous phase 6–8 .…”

Weak thermal stability and low‐burning resistance of the rigid polyurethane foams are the classic problems in the usage of them. Therefore, it is required to improve these problems of the foams while reducing the cost of production. This study investigated the effects of dolomite (DOL) and intumescent flame retardant (IFR) system on thermal and combustion behaviors of rigid polyurethane foams (RPUFs). For this purpose, DOL (5, 10, and 15 wt%) and DOL/IFR (5/5, 10/5, and 5/10 wt%) combinations were added into RPUFs. Thermogravimetric analyses were performed to investigate the thermal decompositions of the foams and the thermal conductivity measurements were performed to examine the effects of DOL and DOL/IFR additions on the thermal insulation properties of the foams. Cone calorimeter and UL 94 tests were performed to investigate the fire resistances of the foams. The test results showed that up to 15 wt% DOL could be incorporated into the rigid polyurethane foams as filler without any problems in the foam productions, and the thermal and the combustion behaviors of the foams were slightly enhanced. In addition, it was determined that IFR should be used to improve the thermal stability and the fire resistance of the DOL added foams. Among DOL/IFR combinations, 5 wt% DOL and 10 wt% IFR addition satisfied the best performance in terms of the thermal stability and the fire resistance with reducing the smoke, CO, CO2 and NO emissions. In general, the additions of DOL and IFR slightly increased the thermal conductivity coefficients of the foams.

Bu araştırmanın amacı, fen bilgisi öğretmen adayları için Phyphox uygulaması kullanılarak geliştirilen bir STEM etkinliğinin uygulanıp değerlendirilmesidir. Bu kapsamda 21 öğretmen adayı ile karma desende bir araştırma yürütülmüştür. Araştırmanın verileri; Baydas ve Goktas (2016) tarafından geliştirilen “Öğretmen Adaylarının Gelecekteki Derslerinde Bilişim Teknolojilerini Kullanma Eğilimleri Ölçeği” ile araştırmacılar tarafından geliştirilen “Çalışma Yaprağı” ve “Etkinlik Değerlendirme Formu” yardımıyla toplanmıştır. Araştırma sonucunda, etkinliğin öğretmen adaylarının gelecekteki derslerinde teknoloji kullanma eğilimleri üzerinde pozitif yönde anlamlı bir etki yarattığı ve öğretmen adaylarının Phyphox yardımıyla üç farklı cep telefonu sensöründen yararlanarak salıncak tasarımları yaptıkları belirlenmiştir. Bunun yanında, öğretmen adaylarının etkinlik ile ilgili olumlu görüşler ileri sürmekle birlikte bu süreçte bazı güçlükler de yaşadıkları saptanmıştır. Elde edilen sonuçlar ışığında bu tür güncel teknolojik uygulamaların fen bilgisi öğretmen eğitiminde sıklıkla kullanılması önerilmektedir.
