İLKÖĞRETİM ALTINCI, YEDİNCİ VE SEKİZİNCİ SINIFLARI, LİSE BİRİNCİ SINIF VE FEN BİLGİSİ ÖĞRETMEN ADAYLARININ FEN BİLGİSİNDEKİ TEMEL BİLGİLERLE GÜNLÜK HAYATI İLİŞKİLENDİRME BECERİLERİ

Bu araştırma; ilköğretim 6., 7., 8., sınıf öğrencileri ile Lise 1 (9. sınıf) ve Fen Bilgisi Öğretmen adaylarının, fen bilgisinin bazı temel bilgilerini günlük hayatla ilişkilendirebilme düzeylerini belirlemek amacıyla yapılmıştır. Araştırma, 2006-2007 öğretim yılında Ankara İl Merkezindeki muhtelif okulların 6., 7. ve 8. sınıf öğrencileri ile 9. sınıf öğrencilerine ve Fen Bilgisi Öğretmen adaylarına; fen konularını günlük hayatla ilişkilendirme testi hazırlanması, uygulanması ve değerlendirilmesi ile gerçekleştirilmiştir. Pilot çalışma için hazırlanan test 8. sınıf öğrencilerinden toplam 106 kişiye uygulanmıştır. Yapılan bu pilot çalışmanın verileri SPSS 12.0 paket programına girilerek güvenilirlik kat sayısı =0,73 olarak bulunmuştur. Geliştirilen bu test; 6. sınıf öğrencilerinden 61 kişiye, 7. sınıf öğrencilerinden 70 kişiye, 8. sınıf öğrencilerinden 258 kişiye, Lise 1. sınıf öğrencilerinden 94 kişiye ve Fen Bilgisi Öğretmen adaylarından ise 58 kişiye uygulanmıştır. SPSS 12.0 paket programı kullanılarak cinsiyetin öğrenci başarısında etkili olup olmadığını belirlemek için t-testi, bu sınıflar arasında anlamlı bir başarı farkının olup olmadığını belirlemek için ise Tek Yönlü Varyans Analizi (ANOVA) uygulanmıştır. Araştırmadan elde edilen verilerin istatistiksel analizi sonucunda fen bilgisinin günlük hayatla ilişkilendirilme düzeyinin düşük olduğu görülmüştür. Bu araştırma ile, sınıf düzeyleriyle fen bilgisini günlük hayatla ilişkilendirme düzeyleri arasında farklılıklar görülmüş; ilköğretimin 8. sınıf öğrencilerinin daha başarılı olduğu, 9.sınıf öğrencilerinin testteki ortalamalarının ilköğretim ikinci kademe öğrencilerinin ortalamalarından da düşük olduğu belirlenmiştir. Bunun yanında fen konularını günlük hayatla ilişkilendirmedeki öğrenci başarısı ile cinsiyet faktörü arasında anlamlı bir ilişki bulunmamıştır. Araştırma sonucunda ayrıca ; 6. sınıf öğrencileri ile lise 1. sınıf öğrencilerinin biyoloji konularını, 7. ve 8. sınıf öğrencileri ile Fen Bilgisi Öğretmen adaylarının ise fizik konularını günlük hayatla ilişkilendirmede daha başarılı oldukları belirlenmiştir..This research was done to determine the level of 6 th , 7 th , 8 th year primary school and 1 st class high school students and the candidates of science teachers for relating science with their daily life. The search was executed by prepearing tests for relating science subjects with daily life, practicing and estimating them to the students of 6 th , 7 th , 8 th year primary school and 1 st year high school students and the candidates of science teachers in various schools in Ankara city centre in 2006-2007 school years. The test prepeared for pilot study was practiced to total 106 person of 8 th year students. The datums of this pilot study was found that the reliability of coefficient is =0.73 by entering the packed software of SPSS 12.0 This imroued test was practiced to 61 of 6 th year students, 70 of 7 th year students, 258 of 8 th year students, 94 of 1 st year high school students and 58 of candidates of science teachers. By using SPSS 12.0 packed software, t-test is practiced to determine whether the gender is effective on the success of the student or not. To determine if there is a meaningful success difference between this classes Analyze of One Way Variance (ANOVA) is practiced. As a result of statiskal analyze of the datums after the research, it was found out that the level of relating science with everday life is quite low. By this search, the differences are seen between the class level and the level of relating science with daily life. It is determined that 8 th year of primary school students are more successful, and the test avarage of 9 th year students even is lower than the students of second rank. Beside this, a meaningful relation is not found between the student success of relating the science with daily life and gender factor. Furthermore, as a result at the research it is determined that the 6 th year primary and 1 st year high school students are successful in biology; and 7 th and 8 th year students with the candidates of science teachers are succesful in physics in terms of relating them with their everyday life

A SEMIOTIC EVALUATION OF COVER IMAGES OF THE TEN MOST HELD TURKISH POP MUSIC ON THE 2021 SPOTIFY LIST

Semiotics, or semiotics as it is commonly known, is an interdisciplinary research field that examines the sign strings of studies in many fields such as music, sociology and linguistics. Today, semiotics, which makes metaphorical analysis of various disciplinary fields such as literature, art, music and cinema and has a wide range as a field of study, has been an important communication tool in this sense. The science of semiotics, which has both a principled and free movement environment due to its multidisciplinary structure, has explained objects, figures and situations in this way by revealing the meaning and establishing a connection with the place of that meaning in society. Among these fields, especially in music, graphic designs used in the creation of album covers, concert posters, posters have an important role in conveying the message that the musical product wants to convey. In this research, it is aimed to make a semiotic analysis of the cover images of the ten most listened songs in the field of Turkish pop music in the Spotify 2021 list. Within the scope of the purpose of the study, cover images were evaluated semiotically in terms of elements such as writing styles, color preferences, use of figures and objects. In this case, questions such as how the current album cover designs examined are, what kind of differences they have with the album covers of the past, how the effects, colors, figures, etc. used in the design of the album covers are, whether the album covers are meaningfully compatible with the title of the album. According to this analysis, ten cover images determined by scanning reliable sites on the internet were reached. The covers were analyzed semiotically in four groups with the criteria of object, human, digital photograph and color under the elements of signified and signifier according to the sign method created by F. Saussure. In addition to these examinations, the content of the lyrics in the albums was also evaluated and it was determined whether they were meaningfully compatible with the album title and cover image. In the light of the evaluations made, it has been concluded that some of the album covers are compatible with the name of the album and some are not. It has been observed that the design of the album covers is influenced by the general fashion sense of the global music industry, and for this reason, they are far from the old album covers in terms of design and meaning

Catalytic performance improvement with metal ion changes for efficient, stable, and reusable superoxide dismutase-metalphosphates hybrid nanoflowers

Herein, for the first time, the flower-like enzyme-inorganic hybrid nanoflowers were synthesized using a superoxide dismutase (SOD) as organic material and selected some metal ions (Cu(II), Co(II), Mn(II) and Zn(II)) as inorganic parts at optimum pH value. The synthesis steps of SOD @metalphosphates hybrid nanoflowers were verified by XRD, FT-IR, FESEM, and EDX. The synthesized nanoflowers were utilized as a catalyst in the reduction of organic pollutants (2-nitrophenol (2-NP) and Rhodamine B (RhB)) with NaBH4 in aqueous media for catalytic properties and susceptibility. The activities of both the substrate and the metal center of the catalyst were determined in the increasing rate order of RhB > 2-NP for substrate and SOD@Cu-3(PO4)(2)center dot 3H(2)O > SOD@Co-3(PO4)(2)center dot 8H(2)O > SOD@Mn-3(PO4)(2)center dot 7H(2)O > SOD@Zn-3(PO4)(2)center dot 4H(2)O hNfs for catalysts. The catalytic data provided herein by using SOD @metalphosphates (SOD@Cu-3(PO4)(2)center dot 3H(2)O, SOD@Co-3(PO4)(2)center dot 8H(2)O, SOD@Mn-3(PO4)(2)center dot 7H(2)O and SOD@Zn-3(PO4)(2)center dot 4H(2)O) nanoflowers suggest that the materials can be effective catalysts for the water-based reduction reaction of organic pollutants
