The aim of this study is to investigate mathematics teachers' views about measurement-evaluation dimension of new Turkish geometry curriculum. With this aim, 15 mathematics teachers who are selected from Artvin, Bayburt, Rize and Trabzon were carried out semi-structured interview. As a result, it was seen that teachers in our samples tend to apply traditional measurement and evaluation approach as they find the new measurement-evaluation dimension difficult and uneasy using the tools and methods. And the teachers are not aware of which tools are to be used in alternative measurement and evaluation approach or they do not know how to use it. Also, there are teachers who have negative views about new approach. These teachers have stated the main issue occurs due to time limitations, crowded classes, lack of tools and materials and density of class hours.

It is very important to identify and correct the mistakes that students make about mathematical concepts. The purpose of this study is to detect the secondary school students' misconceptions about functions in the 2009-2010 academic year. Research data was collected 61 students, included 9 th,10 th and 11 th grade students selected randomly, in Erzincan (2009-2010) academic year. Data collection tools consist of knowledge test and interviews. Frequency tables and percentages were used by analyzing students' explanations as answers to questions on the function information test. Pearson correlation was chosen to state the meaningful difference among the questions, if there is any, on the Function information test also included four different categories. Student, being believed to be in error, were interviewed with the help of data obtained from Function information test. As a result of the interview, it is most commonly observed that students make mistakes to understand whether a graphic is a function graphic or not, and about the demonstration of the table and function especially on the function information test.

A series of crown ethers carrying a pyrene group with nitrogensulfur donor atoms, that differ in having three, four and five sulfur atoms in the macrocycle was designed and synthesized by the reaction of the corresponding macrocyclic compound and 1-bromomethylpyrene. The influence of metal cations such as Mn 2+, Fe2+, Fe3+, Co2+, Ni 2+, Cu2+, Zn2+, Cd2+, Hg 2+, Pb2+ and Al3+ on the spectroscopic properties of the ligands was investigated in acetonitriledichloromethane (1:1) by means of absorption and emission spectrometry. Absorption spectra show isosbestic points in the spectrophotometric titration of Fe2+, Zn2+, Cu2+, Pb2+ and Hg2+. The results of spectrophotometric titration experiments disclosed the complexation compositions and complex stability constants of the novel ligands with Fe 2+, Zn2+, Cu2+, Pb2+ and Hg 2+ cations. The monoazatetrathia crown ether showed good sensitivity for Cu2+ with linearity in the range 5.0×10-72. 5×10-6 M and detection limit of 1.6×10-8 M.

In this study it is aimed to investigate whether university students' attitudes toward the use of PowerPoint as a supporting teaching tool in the lectures change according to variables such as gender, academic units attended. For this purpose, the sample consisted of total 653 students who enrolled, Faculty of Education (N=287), Faculty of Engineering (N=125), School of Economics and Administrative Sciences (N=92) and Vocational School (N=149) in Bayburt University. Data was collected using "attitude toward the use of PowerPoint" scale. Additionally, students' opinions of the use of PowerPoint as a supporting teaching tool was collected from their responses to a questions form developed by researchers, then written documents analyzed to reveal their opinions with respect to the use of PowerPoint. The data obtained was statistically analyzed (ANOVA). It was found that there is no any statistically meaningful difference in the participants' attitude toward the use of PowerPoint in respect to gender, but there was significant difference in the participants' attitude toward the use of PowerPoint according to academic units attended. Recently, the findings were discussed in terms of the use of PowerPoint as a supporting tool in the lectures and its importance.

The aim of this study is to develop an attitude scale towards multi-grade classrooms (AMC) for elementary school teachers who work in the Multi-grade Classrooms. The research was carried out with the total 215 elementary school teachers in Tokat and Samsun provinces in Turkey. The study carried out in five stages that are literature review, creating item pool, expert opinions, administer of scale and computing the reliability and validity. The five point rating scale consisted of 50 items was developed. The draft scale obtained has been applied to the total 205 elementary school teachers and as a result of factor analysis; the number of items in draft scale was reduced to 43. The Cronbach-Alpha internal integrity coefficient of the final version of the scale was found to be 0.81 after factor analysis was carried out. The scale has been ready to be used.

The study aims to explore the effect of preparing and presenting powerpoint slides on prospective teachers' biology achievement and attitudes toward biology. The sample of the study was 109 freshman students from Pre-School Education Department at Atatürk University in Turkey. The sample was randomly assigned as control group consisted of 53 students and experimental group consisted of 56 students. The experimental group was taught by powerpoint presentations preparing and presenting by prospective teachers while the lesson was conducted through traditional approach in the control group. Results indicated that preparing and presenting powerpoint slides had a significant effect on prospective teachers biology achievement and attitudes towards biology.
