Abstract: The purpose of this study is to determine the views of students about blog use for supplementary purposes in courses. Survey research method was applied for the quantitative dimension of the study, and the semi-structured interview technique was used for the qualitative dimension. Regarding the quantitative dimension of the study, the participants were 68 undergraduates at a university in Turkey; as for the qualitative dimension, the participants were nine students from the same group. The research results revealed that the students’ interest in courses, the duration of their preparation for exams, and their socialization did not differ with respect to the variables such as their gender and the availability of the Internet connection. On the other hand, the results demonstrated that there was a significant difference in favour of female students in terms of the variable of achievement. Also, in the study, it was revealed that the students who had frequently followed the course blog and their personal blogs had higher levels of achievement and interest in the course.

Abstract: The purpose of the current study is to determine opinions of teachers on using internet searching strategies in an elementary school. The study conductad through qualitative method was designed on survey research model. Participants were consisted of 21 teachers at an elementary school in Eski ehir in Turkey. Questionnaires consisting of open-ended questions were used to collect data in the spring semester of 2008, which were analyzed through inductive coding technique. Findings reveal that elementary school teachers primarily use Google for searching on the internet. It is revealed that internet search strategies applied by teachers differ between the inception and the development processes of the search. In addition, teachers have several problems like irrelevant information, accessing insufficient information, accessing websites with virus threats while searching. A need for in-service training regarding the ways of accessing and retrieving information from nternet was stated along with creative suggestions in accordance with the content and structure of the instructional process assumed.
An Elementary Proof of the Mean Inequalities  [PDF]
Ilhan M. Izmirli
Advances in Pure Mathematics (APM) , 2013, DOI: 10.4236/apm.2013.33047

In this paper we will extend the well-known chain of inequalities involving the Pythagorean means, namely the harmonic, geometric, and arithmetic means to the more refined chain of inequalities by including the logarithmic and identric means using nothing more than basic calculus. Of course, these results are all well-known and several proofs of them and their generalizations have been given. See [1-6] for more information. Our goal here is to present a unified approach and give the proofs as corollaries of one basic theorem.

On Some Properties of Digital Roots  [PDF]
Ilhan M. Izmirli
Advances in Pure Mathematics (APM) , 2014, DOI: 10.4236/apm.2014.46039

Digital roots of numbers have several interesting properties, most of which are well-known. In this paper, our goal is to prove some lesser known results concerning the digital roots of powers of numbers in an arithmetic progression. We will also state some theorems concerning the digital roots of Fermat numbers and star numbers. We will conclude our paper by an interesting application.

An Algorithm to Generalize the Pascal and Fibonacci Matrices  [PDF]
Ilhan M. Izmirli
Applied Mathematics (AM) , 2015, DOI: 10.4236/am.2015.66101
Abstract: The Pascal matrix and the Fibonacci matrix are among the most well-known and the most widely-used tools in elementary algebra. In this paper, after a brief introduction where we give the basic definitions and the historical backgrounds of these concepts, we propose an algorithm that will generate the elements of these matrices. In fact, we will show that the indicated algorithm can be used to construct the elements of any power series matrix generated by any polynomial \"\" (see Definition 1), and hence, it is a generalization of the specific algorithms that give us the Pascal and the Fibonacci matrices.
Software Competences of Geomatic Engineering  [PDF]

International Journal of Geosciences (IJG) , 2015, DOI: 10.4236/ijg.2015.612102
Abstract: In this paper, it is both intended to effectively transfer and emphasize the relationship between geospatial data and software applications while presenting the learning activities which required software competences and presented some software techniques related with geomatic engineering. Effective software competence in geomatic is required for both the combination of information-communication technologies and interdisciplinary collaborative learning activities. The essential way to keep up with future competences is adaptation to different types of information technologies. Today, it is obviously seen that the using of interest-activated technology is a sine qua non condition of engineering education. The main focusing point of this paper is to present some learning suggestions while developing a software related course content in Geomatic to empower engineering education.
EDUCATIONAL TECHNOLOGY IN PRACTICE Research and Practical Case Studies from the Field
Reviewed by Ozden SAHIN-IZMIRLI
The Turkish Online Journal of Distance Education , 2010,
Abstract: The book starts with an explanation of the reason why the terms found in the book are sometimes used in place of each other. The editors stated that when technological tools are used to establish an effective and productive study process in education, the concept of learning technology is used instead of educational technology. The editors of the book considers the field as complex and vague in terms of the fact that the meanings of the concepts are close to each other in the field of educational technology and that the field provides an opportunity for inter-disciplinary studies. However, according to the editors, this vagueness and complexity shows the superiority of the field. This superiority is explained with the fact that the field of educational technology requires upper-level skills of problem solving and critical thinking and that it presents a multi-dimensional and inter-disciplinary study field. The book was edited by Wanjira Kinuthia and Steward Marshall. Wanjira Kinuthia, an assistant professor at Georgia State University, works in the Department of Middle-Secondary Education and Instructional Technology. Steward Marshall, a professor at the University of the West Indies, is the director of the Distance Education Centre. The book includes five sections and 21 chapters. These sections are “Materials, Methods, and Modalities”, “Technology Implementation and Integration Issues”, “Student Engagement and Learning”, “Building Capacity”, “Using Technology for Performance Improvement and Productivity Enhancement”.
A Preliminary Investigation into Critical Thinking Skills of Urban High School Students: Role of an IT/STEM Program  [PDF]
Mesut Duran, Serkan Sendag
Creative Education (CE) , 2012, DOI: 10.4236/ce.2012.32038
Abstract: This paper reports the development of critical thinking of urban high school students in an IT/STEM program-using information technology (IT) within the context of science, technology, engineering, and mathematics (STEM). The study used a quasi-experimental time-series design, involving 47 initial participants in an eighteen-month intervention period. Data were collected from the Test of Everyday Reasoning (TER), which provides an overall score on critical thinking skill (CTS) and five sub-scale scores (analysis, inference, evaluation, inductive reasoning, and deductive reasoning). Findings indicate that based on a mean score of 15.77, the average participant scored between the 16th and 19th percentiles at the beginning of the program compared to an aggregated national sample. Participants who completed the program and responded to all three time-series TER tests (14) significantly improved their critical thinking skills throughout the program. Program completers’ overall post-program CTS test score was more homogeneous than the pre-program scores with a 20.07 mean score. In addition, data showed significant improvement in inductive reasoning skills of the program participants during the first nine months with continuing improvement in the second nine months. In contrast, data presented improved inference skills during the first nine months with significant gains during the second half of the program. The study estimates the relative effects of IT/STEM experiences with technology-enhanced, inquiry and design-based collaborative learning strategies on CTS of urban high school students.
DNA Methylation
Muzeyyen Izmirli,Turan Tufan,Davut Alptekin
Arsiv Kaynak Tarama Dergisi , 2012,
Abstract: Methylation is a chemical reaction in biological systems for normal genome regulation and development. It is a well known type of epigenetic mechanism. Methylation which regulates gene expression via epigenetic events like gene activation, repression, and chromatin remodelling, consists of two methylation systems. One of these systems is DNA methylation whereas the other is protein (histone) methylation. These systems are associated with some fundamental abnormalities and diseases. This review highlights the role of methylation in normal genome function, how it can be arranged and which diseases it cause. Furthermore, the role of methylation in some diseases and its functions in epigenetic mechanism has been reviewed. [Archives Medical Review Journal 2012; 21(4.000): 274-282]
Towards Earthquake Shields: A Numerical Investigation of Earthquake Shielding with Seismic Crystals  [PDF]
Baris Baykant Alagoz, Serkan Alagoz
Open Journal of Acoustics (OJA) , 2011, DOI: 10.4236/oja.2011.13008
Abstract: Authors numerically demonstrate that the seismic surface waves from an earthquake can be attenuated by a seismic crystal structure constructed on the ground. In the study, seismic crystals with a lattice constant of kilometer are investigated in the aspect of band gaps (Stop band), and some design considerations for earthquake shielding are discussed for various crystal configurations in a theoretical manner. Authors observed in their FDTD based 2D wave simulation results that the proposed earthquake shield can provide a decreasing in magnitude of surface seismic waves. Such attenuation of seismic waves might reduce the damage in an earthquake.
