Content and Language Integrated Learning Practices in Kazakhstan Secondary Schools During COVID-19 Pandemic
No full textA case study was initiated from the perspective of three research questions: 1) CLIL teachers’ practices at secondary schools of Aktobe during COVID-19 pandemic; 2) challenges for the teachers; 3) support provided for the teachers. The research methodology combined face-to-face personal interviews, and non-participant observation. Data analysis was conducted in line with Mayring’s (2020) approach to content analysis and by means of categorization into specific themes that emerge from teachers’ conceptualization of their CLIL practices. The analysis of teachers’ reflections on their experiences and challenges of using the CLIL approach during the pandemic, support provided to them and teachers’ attitudes towards the approach is presented in the paper. Research data on the secondary schools Science teachers’ CLIL practices in a remote learning setting was categorized related preparation to teaching, resources used by the teachers, students’ interaction during the lessons, and stakeholders’ attitudes and perceptions of the approach. The obtained data enables to understand Science teachers’ practices in terms of using the CLIL approach in Kazakhstani secondary schools in the period of COVID-19 pandemic, and will contribute to teacher development and preparation for successful CLIL realization in a non-traditional classroom. © 2022 by the authors; licensee CEDTECH by Bastas
Designing the 'new normal': Key insights from the pandemic for transforming online learning going forward
No full textIndexación: Scopus.The deep disruption to education caused by the move to online learning during COVID-19 was unprecedented. While most educational stakeholders adapt to the transition back to a “new normal”, it seems an obvious time for constructivist reflection on the lessons learned. The aim of this longitudinal inquiry was to examine the experiences of higher education learners in Chile during the pandemic for potential insights to be gained. The focus was on students in multi-disciplinarian fields and the changes to their perspectives, practices, and identities. Working within the qualitative paradigm, data was gathered using interviews (n=22), surveys (n=1,054, n=1,137, n=205) and field notes. Learners’ experiences were mapped against contemporary e-learning theory and 21st century learner identity goals. Through this lens, pedagogical practices, course designs, and uses of technology reflected in online spaces were found to influence learners and their learning in complex ways. Two key themes emerged in the analysis: (1) exposure to conventional pedagogy, information transfer and assessment-driven designs and technology challenges online, left students discouraged with their learning progress and disparaging of their future workplace preparedness and (2) students who experienced learner-centered practices online, supported by contemporary learning theory and community-building course designs and technologies, underwent transformative changes to their learning and identities and feeling confidently qualified for their post study careers. In view of the increasing role e-learning will play in this century, we believe further empirical research of this kind into a myriad of global, digital learning contexts, could help transform online learning and learners in our new post pandemic reality. © 2023 by authors; licensee CEDTECH by Bastas, CY.https://www.cedtech.net/article/designing-the-new-normal-key-insights-from-the-pandemic-for-transforming-online-learning-going-1338

Preliminary Development of an Item Bank and an Adaptive Test in Mathematical Knowledge for University Students
No full textIn the last decades, the development of computerized adaptive testing (CAT) has allowed more precise measurements with a smaller number of items. In this study, we develop an item bank (IB) to generate the adaptive algorithm and simulate the functioning of CAT to assess the domains of mathematical knowledge in Argentinian university students (N=773). Data were analyzed from the Rasch model. A simulation design created with the R software was used to determine the necessary items of the IB to estimate examinee ability. Our results indicate that the IB in the domains of mathematical knowledge is adequate to be applied in CAT, especially to estimate average ability levels. The use of CAT is recommended for rapidly generating indicators of the knowledge acquired by students and to design educational strategies that enhance student performance. Results, constrains, and implications of this study are discussed.Fil: Ghio, Fernanda Belén. Universidad Nacional de Córdoba.

Students' views on mathematics in single-sex and coed classrooms in Ghana
No full textIn this study, we investigated students’ views on themselves as learners of mathematics as a function of school-by-sex (N = 2034, MAge = 18.49, SDAge = 1.25; 12th-grade; 58.2% girls). Using latent variable Structural Equation Modeling (SEM), the measurement and structural equivalence as well as the equality of latent means of scores across single-sex and coed schools were tested. Findings regarding the latent mean differences revealed that girls in single-sex schools had significantly higher mathematics self-confidence than did students’ in coed schools. Girls in coed schools had significantly lower mathematics self-concepts than did boys in single-sex, girls in single-sex and boys in coed schools. Girls in single-sex schools had significantly higher family encouragement than students’ in all other school types. Moreover, a more complex dynamics were found on the teacher quality variate. This paper argues for a deeper understanding of sex-school interaction and of possible causes of students’ views on mathematics.Peer reviewe
Enhancing Physical Activity Discussions of Oncologists for People Living with and Beyond Cancer: Implementing a Webinar Training Module
No full textOncologists hold a unique position to facilitating physical activity (PA) behaviour change in cancer survivors as they are highly trusted. Despite improved PA participation following recommendations by oncologists, many oncologists do not regularly discuss PA with survivors. Oncologists experience low knowledge and confidence with PA discussions, thus there is a need for formal training, targeting these outcomes, to facilitate PA discussions. The purpose of this study was to assess the feasibility of a theory-based webinar for enhancing oncologists’ PA discussion practices. Oncologists and oncology residents/fellows (N=13) attended a single 35-minute or 60-minute webinar. Outcomes were assessed pre- and post- webinar. Results demonstrated the feasibility of both a 35-minute and 60-minute webinar for oncologists and oncology residents/fellows. However, there were advantages unique to the 60-minute group, with the inclusion of discussion activities, that further enhanced the webinar experience. Future interventions should target changes in PA discussion practices with formal training.M.Sc

Phys., 9 (2013) 717) that in a two-level multiplex network, a gradual change in the value of the "interlayer" strength p can provoke an abrupt structural transition. The critical point p * at which this happens is system dependent. In this article, we show in a similar way as in (Garrahan J. P. and Lesanovsky I., arXiv:1406.4706) that this is a consequence of the graph Laplacian formalism used in the above-mentioned paper by Radicchi and Arenas. We calculate the evolution of p * as a function of system size for ER and RR networks. We investigate the behavior of structural measures and dynamical processes of a two-level system as a function of p,b yM o n t eC a r l o simulations, for simple particle diffusion and for reaction-diffusion systems. We find that as p increases there is a smooth transition from two separate networks to a single one. We cannot find any abrupt change in static or dynamic behavior of the underlying system
First Report of Bacterial Canker of Kiwifruit Caused by <i>Pseudomonas syringae</i> pv. <i>actinidiae</i> in Turkey
No full text A new disease was observed during the spring and autumn of 2009 and 2010 on kiwifruit plants (Actinidia deliciosa cv. Hayward) in Rize Province of Turkey. Disease incidence was estimated as 3% in approximately 10 ha. Symptoms were characterized by dark brown spots surrounded by yellow halos on leaves and cankers with reddish exudate production on twigs and stems. Eight representative bacterial strains were isolated from leaf spots and tissues under the bark on King's B medium (KB) and identified as Pseudomonas syringae pv. actinidiae on the basis of biochemical, physiological (1,2), and PCR tests (3). Bacteria were gram negative, rod shaped, and nonfluorescent on KB; positive for levan production, sucrose and inositol utilization, and tobacco (Nicotiana tabacum cv. White Burley) hypersensitivity; and negative for growth at 37°C, oxidase, potato soft rot, arginine dihydrolase, urease, arbutin, erythritol, lactic acid, aesculin hydrolysis, gelatin liquefaction, and syringomycin production. Identity of the eight isolates was confirmed by PCR using P. syringae pv. actinidiae-specific primers PsaF1/R3 to generate a 280-bp DNA fragment (3). P. syringae pv. actinidiae reference strain NCPPB 3739, and CJW7 from Jae Sung Jung, Department of Biology, Sunchon National University, Korea, were employed in all biochemical, physiological, and molecular tests as positive controls. Pathogenicity was confirmed by artificial inoculation of 2-year-old A. deliciosa cv. Hayward. A bacterial suspension (108 CFU ml–1) was injected into kiwifruit twig tips, stems, and leaves with a hypodermic syringe, and the inoculated plants were placed at 25 to 28°C and 80% relative humidity growth chamber for 3 weeks. First symptoms were observed on leaves within 5 days after inoculation and on twigs after 20 days. No symptoms were observed on control plants that were inoculated with sterile water. Reisolation was made from dark brown lesions surrounded by yellow halos on leaves and cankers on twigs and stem and their identities were confirmed using the techniques previously described. All tests were performed three times and pathogenicity tests employed three plants for each strain. To our knowledge, this is the first report of P. syringae pv. actinidiae causing disease on kiwifruit in Turkey. Kiwifruit production in Turkey has expanded rapidly during the last 10 years ( http://www.tuik.gov.tr ) and phytosanitary measures are needed to prevent further spread of the bacterium to other kiwifruit orchards.

© 2023 by authors; licensee EJSME by Bastas.Technology is recognized for its potential to implement exploration tasks. The ease and speed with which it becomes possible to observe many cases of a situation, allows the development of conjectures and brings conviction about their veracity. Mathematical proof, assumed as the essence of Mathematics, tends to appear to the students as something dispensable. Based on KTMT – Knowledge for Teaching Mathematics with Technology model, this study intends to understand the impact of the teachers’ knowledge on mathematical proof in a context of technology integration. The study adopts a qualitative and interpretative methodology, based on case study, analyzing the practice of one teacher. The conclusions emphasize the relevance of the teacher’s MTK – Mathematics and Technology Knowledge, and TLTK – Teaching and Learning and Technology Knowledge. The teacher's MTK guides her decisions, leading her to focus on helping students understand the meaning of conjecture and proof, valuing, at the same time, the relevance of algebraic manipulations. However, the teacher’s TLTK guides her practice, where the knowledge about the students is determinant. The study provides evidence about the difficulty of articulating proof and technology, but it also clarifies the relevance of this articulation and of how the teacher’s KTMT can impact the teacher’s decisions.publishersversionpublishe
Multi-Word Combinations in Science Communication. A Corpus-Driven Study of University Press Releases
No full textEntrepreneurial universities sponsor their research through the media to increase their
popularity. This in turn may engender a biased representation of scientific knowledge in the
media. We present the results of a quali-quantitative analysis of phraseology characterizing
press releases (PRs) issued by universities and focusing on published research. Our investigation
aims to identify typical n-grams in university PRs and their main purposes. The study is based
on a developmental 68,913-word collection of university PRs. 5-word n-grams were assigned
categories and functions. Results contribute to the characterization of PRs as a hybrid genre at
the crossroads between news and ads. Moreover, findings add knowledge about this specific
type of PRs, which cover some of the same functions as scientific discourse while at the same
time enhancing promotional features. This is shown by the recurrent use of phrasal units
fulfilling both informative and promotional needs to the detriment of others only fulfilling
informative functions
