No full textTheaim of this study is to survey on the preschool teacher candidates' mathematical literacy and their attitudes towards mathematics education according to the type of high-school and the field of which they graduated, and to examine the effect of mathematical literacy on the attitude towards early mathematics teaching. This study is a descriptive research in which survey model is used. The study group of this study consists of 195 pre-school teachers. The data collection tool "Mathematical Literacy Self-Efficacy Scale" and "The Tool Identification of Pre-school Teachers' Attitudes towards Early Mathematics Education" has been used in this research. Datum of the research has been analyzed by using SPSS 18 package software. Findings of the research indicated that there is a statistically significant difference between the mathematical literacy of preschool teacher candidates and the type of high-school they graduated from, and between the attitudes of pre-school teacher candidates towards pre-school mathematics teaching and the high-school field of which they graduated (p0.05)

No full textThe objective of this study is to determine the views of maths teachers who have inclusive students in their classes and students' parents regarding the educational applications within a qualitative framework in detail. Being among the qualitative research approaches, the method of 'case study' was used in the study. The participants were selected among teachers working at secondary education schools in Bulancak and Dereli districts of the central Giresun, as well as the parents of inclusive students receiving education at these schools. The study data were collected via an open-ended questionnaire being developed and for that purpose, the "Teacher's Questionnaire Form" and "Parent's Questionnaire Form" were developed by researchers. The method of content analysis was used in the data analysis. As a result of the study, majority of parents were observed to have expected their children to be able to perform the basic mathematical processes and adapt them into the daily life. It was also determined that a great majority of participant teachers conducted the familiar 'teacer-centered' method in the process of inclusive applications. In addition to this, teachers emphasized that they needed to be informed about the inclusive education by experts

No full textControversies in the management of acute tonsillitis: an evidence-based review
No full textBACKGROUND: Patients admitted with acute tonsillitis generate a substantial workload for the National Health Service (NHS), placing huge financial pressures on an already overstretched budget.OBJECTIVE OF REVIEW: Due to the difficulty of accurate diagnosis and varying practices across the UK, there exist a number of controversial areas and non-standardised practice. These will be highlighted and tackled within this article.TYPE OF REVIEW AND SEARCH STRATEGY: A literature review, last performed in September 2013, searched PubMed citing variations on the areas of controversies with 'tonsillitis', 'pharyngitis' and 'pharyngotonsillitis' - from 1956 to present with language restrictions. Excluded articles included those regarding sore throat after tonsillectomy and peritonsillar abscess.EVALUATION METHOD: Titles and abstracts were initially screened, and full text of potentially relevant articles obtained. The bibliographies of articles were searched for relevant references. The references were then compiled and reviewed independently by two authors (JB & TB), overseen by the senior author (EK).RESULTS: (i) Diagnosis and investigation: Use of the Centor criteria is inadequate within the secondary care setting. Blood testing is unnecessary in the majority of cases where patients do not require admission, as they are unlikely to change management. (ii) Antibiotics: Antibiotics are likely to be indicated in all those presenting to secondary ENT care, with penicillin being the antibiotic of choice for first-line therapy. (iii) Corticosteroids: Moderate evidence supports the benefit of steroid administration in this patient cohort, advocating a single dose initially followed by reassessment. (iv) Analgesia: Paracetamol and NSAIDs have good evidence of action. Codeine should be used with caution in the paediatric population. (v) Reduced admission rates and early discharge: There is evidence suggesting that a trial of medical therapy prior to admission is beneficial in reducing rates of admission and length of stay.CONCLUSIONS: Management of acute tonsillitis within a secondary care setting largely consists of anecdotal or relatively low-quality evidence. Thus, much evidence from management comes from expert opinion or practice within a primary care setting. Management across the UK can also vary greatly. An evidence-based review of best practice has been presented here, but further evidence will be required in the future examining the significance of corticosteroids and antibiotic administration in this patient cohort specifically, ensuring practice is evidence based and clinically relevant.</p
Exceptional visible-light-driven photocatalytic activity over BiOBr-ZnFe2O4 heterojunctions
Full text linkAn ultrasound-assisted, precipitation–deposition method has been developed to synthesise visible-light-responsive BiOBr–ZnFe2O4 heterojunction photocatalysts. The heterojunctions with suitable BiOBr/ZnFe2O4 ratios have a fascinating micro-spherical morphology and exhibit exceptional photocatalytic activity in visible-light degradation of Rhodamine B
