Mass attenuation coefficients for 12 selected moderate-to-high atomic-number elements have been obtained from good-geometry measurements made at five 241Am photon energies of significant emission intensity. Particular interest focuses on measured values for photon energies close to absorption edges. Comparisons with renormalized cross-section predictions indicate agreement to within stated error limits for the majority of cases. Significant discrepancies (>10%) are noted

Bu arastirmanin amaci, onuncu sinif fizik dersinde uygulanan farklilastirilmis ogretimin sinif iklimine etkisini arastirmaktir. Arastirmada nitel arastirma yaklasimlarindan birisi olan durum calismasi metodolojisi kullanilmistir. Arastirmanin calisma grubunu, Erzurum ilinde uc farkli lisede ogrenim gormekte olan toplam 84 onuncu sinif ogrencisi olusturmustur. Bes hafta suren uygulama boyunca fizik dersi farklilastirilmis ogretim ile islenmistir. Dersleri ogrencilerin kendi ogretmenleri anlatirken arastirmacilardan birisi sinif ortamini gozlemlemistir. Arastirmanin verileri “Sinif Iklimi Gozlem Formu” (SIGF) kullanilarak toplanmistir. Toplanan verilerin analizinde betimsel analiz kullanilmistir. Sonuc olarak farklilastirilmis ogretimin olumlu bir sinif iklimi olusturdugu gozlemlenmistir. Bu sonuctan yola cikilarak ogrencileri ile iletisim kurmakta zorlanan ogretmenlerin siniflarinda farklilastirilmis ogretim kullanmalari tavsiye edilebilir.

The Ll, Lα, Lβ and Lγ x-ray production cross-sections were measured for seven elements in the atomic range 74 ≤ Z ≤ 92 at 31.635 keV. The values of Li subshell fluorescence yields (ω1, ω2 and ω3) were measured for the same elements using these measured cross-section values and the theoretical Li subshell photoionization cross-sections, Coster–Kronig transition probabilities and emission rates. The measured x-ray production cross-sections values are in general agreement with the theoretical values evaluated using L subshell fluorescence yields, Coster–Kronig transition probabilities, emission rates and subshell photoionization cross-sections.

The purpose of this study is to investigate whether students are more successful on abstract or illustrated test questions. To this end, the questions on an abstract test were changed into a visual format, and these tests were administered every three days to a total of 240 students at six middle schools located in the Erzurum city center and surrounding districts. After the data obtained from the study were examined, it was concluded that students were more successful in illustrated (visual) tests. Keywords: Illustration, Achievement, Concrete, Abstract

The aim of this study is to investigate high school students? views about teaching with 7E model in the unit of electromagnetism. This study carried out with 52 eleventh grade (15-16 years) in two classrooms of a public high school. This study was designed as an action research. The data for the study were collected means of individual interviews. In the study, 12 students were interviewed. Six of the interviews focused on the students? conceptual developments while the rest of the six interviews were about the process and teaching models. The interviewees were selected on the basis of their achievement levels such as high achievers, moderate achievers and low achievers. According to the interviews, it is identified that students have positive views about the application of 7E learning model.

This research aims to investigate the ways in which pre-service physics teachers interact with computers, which, as an indispensable means of today's technology, are of major value in education and training, and to identify any misconceptions said teachers may have about computer-aided instruction. As part of the study, computer-based physics course packages were designed by the researchers and computer-aided assignments were prepared by the pre-service physics teachers. At the end of the study, Physics Achievement Tests were administered to the sample pre-service teachers. The research study group included 50 pre-service physics teachers who were taking classes under the Physics Education Department of Kazim Karabekir Faculty of Education at Ataturk University during the 2015-2016 Fall semester. The research data were analysed using SPSS software packages. The study concluded that the computer-aided science courses were effective, and that pre-service physics teachers had misco...

The aim of this study was to investigate the impact of the course materials developed in accordance with 7E model in the unit of electromagnetism in high school physics class on students' conceptual success. The present study was conducted with a total of 52 11th grade students in two separate classrooms at a high school. The action research design was used as the research method. The data of the study were collected through worksheets, open-ended and multiple-choice conceptual achievement tests and individual interviews. The worksheets, which were developed in order to ensure conceptual change and development based on experimental activities, were prepared and administrated in accordance with 7E model. In the research, 6 students with high level, moderate level and low level of conceptual changes were interviewed about their achievements. The activities and materials, which were applied according to the average scores of students, were found to be effective on conceptual develo...

The most common learning theories in science teaching are developed by Piaget, Vygotsky, Bruner, Gagne and Ausebel. In addition to these, learning cycle approach and constructivism which are defended by many educational researchers and studied on effectiveness of science education in last 30 years have an important place. In this study, these theories are discussed briefly and especially application types of constructivist approach on science teaching are described in detail for models 4E,5E and 7E. Besides, necessary suggestions are made with emphasis on contributions which the laboratory studies of constructivist teaching approach were made.

The purpose of this research was to determine the effectiveness of conceptual based instruction and traditionally designed physics instruction on students? understanding of projectile motion concepts. Misconceptions relevant to projectile motion concepts were specified by related literature on this subject. Projectile Motion Concepts Test was developed according to misconceptions. The data were gained through 43 students in an experimental group taught with learning activities based on conceptual change instruction and 39 students in a control group who followed traditional classroom instruction. The results showed that conceptual change-based instruction caused significantly better acquisition of conceptual change of projectile motion concepts than the traditional instruction.
