The spread of the COVID-19 all over the world have negatively affected many areas, leading to a number changes throughout the world. Being one of these areas, education had to undergone some changes and shifted to distance education during the COVID-19 pandemic. However, distance education has also brought some discussions and problems. This study was carried out to investigate the thoughts of middle school students on distance education and face-to-face education. Based on quantitative research design, this study adopted a phenomenological design Data were collected from a participant group consisting of 240 secondary school students (60 5th grade, 60 6th grade, 60 7th grade and 60 8th grade) through a scale prepared by the researchers. The data were analyzed using SPSS package program with descriptive statistics such as frequency and percentage. As a result of the study It was found that middle school students' views on distance education and face-to-face education differed significantly with regard to parents' education level, gender, grade level and average monthly family income.

In this study, secondary school mathematics teachers' the opinions related to skills-based questions that are compatible with the LGS (High School Transition Exam) question style were examined. Qualitative research methods were adopted in the study. Mathematics teachers working in secondary schools in various parts of Turkey participated in the study. The data is collected via the semi-structured interview form via the "Google drive". Content analysis was used in data analysis. The findings revealed that maths teachers did not agree with the achievements of their skill-based questions, and that the maths course's teaching programs and textbooks were not sufficient to provide effective guidance on skills-based questions. It turns out that teachers need a new course processing process for skill-based questions such as LGS questions. Therefore, it was discovered that they were experiencing a shortage of resources. It was also identified that teachers needed to read books and need in-service training as skill-based questions are questions to understand and interpret what they are reading. Recommendations were made in accordance with the results.

This study aims to evaluate the relationship between mobbing perception and job burnout of secondary school mathematics teachers. Another subject of the study is to find out whether mobbing and burnout perception differs according to gender, marital status, teachers' professional experience, educational background, staff position, and school type variables. The demographical information form developed by the researchers, Maslach Burnout Inventory-Educators Survey, developed by Maslach and Jackson (1981),and Mobbing Scale developed by Cemaloglu and Ertürk (2007) were used as data collection tools. The study was conducted using the survey method. The study participants included 243 mathematics teachers working in public and private secondary schools in a city centre of a province in the Eastern Anatolia Region of Turkey. Although the study findings of burnout perceptions of mathematics teachers do not differ significantly according to the variables of gender, and educational background, they differ according to the variables of marital status, professional experience, staff position, and school type. Mobbing perceptions of mathematics teachers differ according to sub-levels of all variables but the variable of gender and staff position. In addition, a significant relationship has been identified between the mobbing and burnout perceptions of secondary school mathematics teachers. In addition, it has been determined that mathematics teachers' mobbing perceptions are significant predictors of burnout perceptions.

The aim of this study is to develop a valid and reliable measurement tool that measures mathematical visualization perceptions for mathematics teacher candidates. Therefore, the type of study is a survey research. Research was carried out with 462 (336 Female, 125 Male) mathematics teacher candidates from a university located in the Eastern Anatolia region Turkey in 2018-2019 spring season. Exploratory and confirmatory factor analyzes were performed for the analysis of research data. In the process of development of Mathematical Visualization Perception Scale (MVPS); the preparation of the pool of material, testing of the validity of the scope and appearance, conducting the trial application, ensuring the construction validity, calculating the reliability and establishing the final scale were followed. As a result of the exploratory factor analysis, a valid and reliable 5-point Likert-type scale consisting of 42 items, with 6 factors [Additional Drawing (AD), Spatial Thinking (ST), Direction Concept (DC), Relation with Daily Life (RDL), Transition from Algebra to Geometry (TAG) and Transition from Geometry to Algebra (TGA)] was created. Cronbach Alpha internal stability coefficient of these factors was calculated as 0.938. The factor structure of the scale was also confirmed by confirmatory factor analysis. As a result of the findings obtained, it was suggested to the researchers who will study in the related field to evaluate mathematical visualization perceptions of mathematics teacher candidates by using related scale with different sample groups or different variables.

This study aims to develop a valid and reliable scale that shows the secondary school mathematics teachers' evaluations of mathematics homework. A literature review was conducted, and a pool of 41 articles have been prepared for this purpose. Five expert academicians in the field of mathematics education were consulted for the content, construct, and appearance validity of the prepared items. According to the opinions of the field experts, the number of items was reduced from 41 to 38 and applied to 492 mathematics teachers in total. The answers of 20 mathematics teachers were removed from the scope of this study since the answers were either incomplete or coded incorrectly. Therefore, scale forms collected from 472 mathematics teachers were included in this study. This form data was split, Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were done. The construct validity was analyzed via EFA. The scale is a five-factor scale of the five-point Likert scale, which explains the 64.643% of the total variance with 21 items according to EFA results. The reliability of the scale was tested with Cronbach's Alpha coefficient, and the coefficient was calculated as 0.737. The subscales of the scale are titled "Parent Relationship", "Motivation", "Control and Evaluation", "Time" and "Source Use" respectively. CFA was carried out for the scale, and it was concluded that the fit indices are either acceptable or perfect. As a result, a reliable and valid "Teacher Approaches for Mathematics Homework Scale" has been added to the literature.

Purpose: In this study, it was aimed to examine the relationship between the visual mathematics literacy perceptions and its sub-dimension for geometry success levels of prospective teachers. It was also aimed to examine to what extent visual mathematics literacy perception and its sub-dimensions predicted geometry success. Research Methods: This study was designed in accordance with a qualitative, scanning model. The research was carried out with 232 (97 males and 135 females) prospective teachers who studied in Mathematics Education Program at Firat University, Education Faculty, and were selected by simple random sampling method. "Visual Mathematics Literacy Perception Scale" and "Geometry Success Test" were employed in this study as data collection tools. Correlation analysis and multiple regression analysis were used for analyzing the data. Findings: After the data were analyzed, it was determined that there was a positive relationship between the visual mathematics literacy perception and geometry success of prospective teachers. It was also determined that visual mathematics literacy perception is a meaningful predictor of geometry success. Implications for research and practice: Providing trainings on these concepts in the direction of the results, to investigate the concept of perception on other learning areas of mathematics and conducting experimental studies on the perception of visual mathematics literacy are suggested.

Literacy has been defined in the literature frequently. Each new interpretation leads to the idea that the definition can change based on the relevant environment, instruments used and/or the intended objective and there might be different types of literacy including computer literacy, media literacy and visual literacy (Reinking, McKenna, Labbo and Kieffer, 1997; Tuman, 1994). This is also true for computer literacy and mathematical literacy. Therefore, there is a need for studies on computer and mathematical literacy. The objective of the present study was to determine the computer and mathematical literacy levels of secondary school 6th grade students and to reveal the correlation between computer and mathematical literacy levels. The study sample included students that attended provincial, district and village schools, as well as the private schools. The correlation between the computer and mathematical literacy levels of the students that were selected from various regions was determined and the differences based on these levels among the schools were also identified. Since the study aimed to determine the correlation between computer literacy and mathematics literacy of the 6th grade students, relational screening model was utilized in the study. Relational (correlative) studies aim to determine whether there is a correlation between two or more variables (Karasar, 2009). Study population included 139 6th grade students attending a secondary school in Turkey. In the study, "Mathematics Literacy Scale" and "Computer Literacy Scale," which were developed by the author and tested for validity and reliability, were used. The obtained data were analyzed by specific statistical techniques. After the findings were analyzed, results were discussed based on the findings in the literature and necessary recommendations were presented.

The aim of this study is to determine the primary school teachers' views related to the new Turkish primary school mathematics curriculum which was put into practice in the 2005-2006 academic years. A questionnaire developed by the researchers, consists of open ended and closed items, was applied to 60 primary school teachers selected randomly from among classroom teachers in Trabzon, one of the cities in the west Karadeniz Regions of Turkey. Data were analyzed using descriptive analysis technique. The results of this study show that in-service training seminars administered about the new mathematics curriculum were insufficient in terms of their duration, organizations, model activities, and did not provide teachers with sufficient experiences about the new curriculum. It is found that teachers have been aware of distinguishing the new and old mathematics curriculum sufficiently but, teachers have needed knowledge and skills of developing teaching material and implementing student-centered instruction and using alternative assessment methods.(Contains 4 tables.)

In the study Cabri was used for teaching geometry at 4th grade. To investigate students' geometry level, a semi-experimental method was used. In the test group, geometry subjects are taught using Cabri. A multiple choice test was used to collect data as pre and post test. Answers were assigned as 1 to correct, 0 to wrong answers. Data were analyzed using SPSS. It is found that teaching geometry at 4th grade with Cabri has no mean affect on the students learning on information level compared with the traditional education but it is determined that there is a meaningful difference between the other levels.
