A Content Analysis Study towards Researches Regarding Context-Based Learning Approach in Science Education by Between Years 2010 and 2020 in Turkey

The purpose of this study is to study research regarding the context-based learning approach in science education between 2010 and 2020 in Turkey. In this study, a descriptive content analysis method was used to analyzed 86 articles on context-based learning in science education published in 67 different journals. According to some variables such as the year of publication, purpose, area, method, sample, number of samples, data collection tool and data analysis techniques. The Research Classification Form developed by the researchers was used in the analysis of the data. The data were analyzed using descriptive content analysis. Most studies in the field of context-based learning approaches in science education were published in 2019. Most of the studies aimed to determine the effects of the method on achievement and attitude and were carried out within science. The experimental method was preferred among the quantitative methods in the studies. Most of the studies were conducted with secondary school students, and the number of participants was in the range of 0-100. Achievement tests and attitude scales were used extensively as data collection tools, and content analysis and t-test were used extensively in data analysis techniques. According to the results obtained in the research, it is suggested that the researches on the context-based learning approach should be conducted in areas other than science education

Determination of copper, iron, lead, cadmium, cobalt and nickel by atomic absorption spectrometry in baking powder and baking soda samples after preconcentration and separation

The contents of copper, iron, lead, cadmium, cobalt and nickel in baking powder and baking soda samples have been determined by atomic absorption spectrometry after separation and preconcentration. Two different separation/preconcentration methods including APDC-Chromosorb 102 solid phase extraction method and Ce(OH)(4) coprecipitation method have been used for this purpose. The effects of main components of the baking soda and powder were examined. The methods were successfully applied for the determinations of Cu, Fe, Pb, Cd, Co and Ni in the baking soda and baking powder samples purchased from the local markets in Kayseri City-Turkey (recoveries greater than 95%). The results found the two preconcentration methods generally agree with each other. The levels of the analytes in the samples were below the allowed limit values given by Turkish Authorities

The Effects of Educational Level on Breast Cancer Awareness: A Cross-Sectional Study in Turkey

Breast self-examination (BSE) is important for early diagnosis of breast cancer (BC). However, the majority of Turkish women do not perform regular BSE. We aimed to evaluate the effects of education level on the attitudes and behaviors of women towards BSE. A descriptive cross-sectional study was conducted on 413 women (20-59 years), divided into university graduates (Group I, n = 224) and high school or lower graduates (Group II, n = 189). They completed a 22-item scale assessing the knowledge level, attitudes and behaviors regarding BSE, and the Turkish version of the Champion's Revised Health Belief Model. A significantly higher number of women in Group II did not believe in early diagnosis of BC. A significantly higher number of Group I had conducted BSE at least once, and their BSE frequency was also significantly high. Moreover, a significantly lower number of Group I women considered themselves to not be at risk for BC and the scores for perceived susceptibility and perceived barriers were significantly higher. Logistic regression analysis identified the university graduate group to have a higher likelihood of performing BSE, by 1.8 times. Higher educational levels were positively associated with BSE performance. Overall, the results suggest that Turkish women, regardless of their education level, need better education on BSE. Consideration of the education level in women will help clinicians develop more effective educational programs, resulting in more regular practice and better use of BSE
