AN EXAMINATION OF THE NUMBER SENSE PERFORMANCES OF PRESERVICE ELEMENTARY SCHOOL MATHEMATICS TEACHERS

The aim of this study is to examine the number sense skills of preservice elementary school mathematics teachers. This study was conducted by using the survey model among descriptive research methods. A total of 111 preservice teachers studying at second and third grades in the elementary school mathematics teaching program at a state university participated in the study. The data of the study were collected by using the number sense test consisting of 17 questions and developed by Kayhan-Altay (2010). The findings of the study indicated that the number sense performances of preservice elementary mathematics teachers were lower than expected and there was a significant difference in favour of third-grade students. It is considered that the “Special Training Methods I and II” courses and the “Mathematics Curriculum” course, which are taught in third grades and in which subjects such as estimation and making mental calculations, etc. superficially related to number sense are mentioned, may cause this difference. Thus, it was suggested that it was necessary to include courses consisting of number sense and how it can be developed in the curriculum

Examination of the Number Sense Skills of Secondary School Students (6th-8th Grades)

The aim of this study is to examine the number sense skills of secondary school (6th-8th grades) students. The screening model among the descriptive research methods was used in the study. 366 secondary school students (6th-8th grades) in Ordu province participated in the study. The study data were collected by the number sense test developed by Kayhan- Altay (2010). The findings of the study showed that the number sense performances of the students were very low. It was determined that there was a significant difference in favour of the 8th-grade students in terms of the grade levels and in favour of the female students in terms of the gender in the number sense performances between 6th-8th-grade students and 7th-8th-grade students. On the other hand, it was determined that there was a significant positive relationship between the mathematical achievements and number sense performances of the students.

Cytocompatibility of Novel Algae-PLA Membranes For Guided Bone Regeneration At The Level of Types I, III And V Collagen Expression

Statement of the problem: In recent years, the development of innovative and increasingly optimized barrier membranes has focused on marine algae, which as a biopolymer can form a membrane composite together with polylactic acid, thus a combination could show numerous advantages such as antioxidant, antitumor, antibacterial, antiviral as well as antiallergic properties. Furthermore, algae can be produced in an ecologically sustainable way and offer an alternative for patients who refuse treatment with bovine or porcine derived membranes due to ethical or religious reasons.Objective: In this study, four different algal membranes were evaluated for their cytocompatibility with cultured human fibroblasts and osteoblasts.Materials & Methods: Mem-Lok® (Collagen Matrix, New Jersey, USA) as a resorbable collagen membrane and ArgonautTM (Botiss Biomaterials, Zossen, Germany) as a native pericardium GBR/GTR membrane served as reference membranes (RMs). As the negative control cells incubated with normal culture medium only were used. In addition to the cell viability and proliferation assays water soluble tetrazolium (WST), MTT and BrdU, a real time semiquantitative real time PCR (RT-PCR) was developed to investigate in vitro cytocompatibility at the level of types I, III and V collagen expression. A sandblasted- large grid-acid ached titanium surface (Dentcon® Dental Implant Systems, Ankara, Turkey) served as a positive inactive control group for osteoblastic cytocompatibility.Results: For human osteoblasts, the algal membranes showed very good proliferation levels in WST-1, MTT as well as BrdU, indicating cytocompatibility. Examination of the expression behavior of type I, type III, and type V collagen genes showed no evaluable results. However, the RT-PCR should be repeated with the incorporated optimizations to be able to make a statement regarding the success of bone, skin, and connective tissue regeneration after a possible application of the membrane in maxillofacial injury treatment.Conclusion: The investigated collagen types are essential for a proper healing of defects in both soft and bone tissue, as they have fundamental functions such as stability and structural integrity of the tissues

A mixed method study on global warming, climate change and the role of public health nurses from the perspective of nursing students*

Aim: This study aims to evaluate the knowledge and awareness of the nursing students taking the Public Health Nursing course about global warming, climate change, the impact on health and the role of the public health nurse. Design: The study is a mixed method study that includes descriptive data and focus group discussions on global warming, the effects of climate change and the role of the public health nurse. Methods: The data were collected from the nursing faculty of a university located in the Central Anatolia region, where agricultural lands are widespread and climate change effects are most commonly observed. The data were collected from 154 undergraduate senior nursing students between February 2020 and May 2020. Firstly, the students completed the Global Warming Questionnaire that includes 26 items about global warming, climate change, their effects and the role of the public health nurse. Secondly, some students (n = 19) selected through the purposive sampling method participated in online focus group meetings. Results: Our study revealed that 87.7% of the students know the main cause of climate change. The mean scale scores of the students who watch documentaries on the environment, who participate in activities related to the environment, and who know that climate change, sustainable development and health services are closely related were found to be statistically significantly higher (p <= 0.005). The views of the students on global warming and the environment were analyzed in focus group interviews according to five themes (global warming perception; the impact of global warming on health; methods of protection; roles of nurses; nursing education). Conclusion: Global warming and climate change are sensitive and important issues that cannot be evaluated considering only knowledge level. Impact: Global warming, climate change, their effects on health and the roles and responsibilities of nurses need to be included in the nursing curricula so that health professionals who can take measures against global warming, climate change and their health effects can be educated
