Investigation and mapping of natural and artificial radioactivity in sediment samples from Borcka Black Lake, Artvin-Turkey
(Taylor and Francis Ltd., 2022)All living creatures in nature are constantly exposed to ionising radiation, which is emitted from natural and artificial radiation sources. For this reason, it is important to monitor the levels of radioactivity in living ... -
Comparison of the frequency of mathematics teachers' use of mathematics textbooks in face-to-face and distance education
(Mehmet Tekerek, 2022)Understanding the variables that affect the use of textbooks are important for the development of eligible and preferable resources. In this research, the frequency of textbook usage in face-to-face and distance education ... -
Prospective elementary teachers' views on their teachers and their effectiveness
(Nova Southeastern University, 2013)In this paper future elementary teachers reflect on their past experiences and talk about their teachers and the way they were taught, and portray the characteristics of effective and not so effective teachers. The study ... -
Examination of the relationship between statistical literacy levels and statistical literacy self-efficacy of high school students
(Turkish Education Association, 2022)The purpose of this study was to examine the existence of a relationship between statistical literacy levels and statistical literacy self-efficacy of high school students. A total of 163 high school students studying at ... -
Student and school-level factors to predict science literacy for two top-performing countries in PISA 2015: Finland and Singapore
(Routledge, 2022)Finland and Singapore are both top-performing countries in international assessments such as PISA. Finland has been consistently one of the high-achievers regarding not only students’ literacy levels but also educational ... -

On an inverse scattering problem for a class of Dirac operators with spectral parameter in the boundary condition
(Academic Press Inc Elsevier Science, 2012)In this work, we consider the inverse scattering problem for a class of one dimensional Dirac operators on the semi-infinite interval with the boundary condition depending polynomially on a spectral parameter. The scattering ... -
On an inverse scattering problem for a class Dirac operator with discontinuous coefficient and nonlinear dependence on the spectral parameter in the boundary condition
(Wiley, 2012)On the positive semi-infinite interval, we obtained a generalization of the Marchenko method for a Dirac equation system with a discontinuous coefficient and a quadratic polynomial on a spectral parameter in the boundary ... -
Teaching density with a little drama
(Routledge Journals, 2012)This article provides an example of an innovative science activity applied in a science methods course for future elementary teachers at a small university in northeastern Turkey. The aim of the activity is to help prospective ... -
