This study was aimed to explore the interaction between effective physics teacher characteristics, from teachers&rsquo / and students&rsquo / shared perceptions and students&rsquo / motivation. The thesis included two main parts. The first part was quantitative and the characteristics were identified. The second part was qualitative and the characteristics were used as criteria to select two case teachers and the interaction between their characteristics and students&rsquo / motivation was investigated. The questionnaire, in the quantitative part, was administered in 3 regions of Turkey and 3 cities for each region including 214 high school physics teachers. There were two different questionnaires, derived from the quantitative part, to select the two case teachers for the qualitative part. The qualitative data included interviews with the two case teachers and their students, field notes, and videos. The data in the quantitative part was analyzed by descriptive statistics. Findings revealed that there were 38 effective physics teacher characteristics affecting students&rsquo / motivation in physics within 8 categories as perceived by teachers and students. The characteristics were important in terms of students&rsquo / motivation as perceived by teachers more than as perceived by students. The teachers&rsquo / subject matter knowledge and their personal characteristics were the two categories that mostly affected the students&rsquo / motivation. The data in the qualitative part was analyzed by cross case analysis. The findings revealed that the positive characteristics increased students&rsquo / motivation, when the teachers exhibited them. When the teachers did not display the positive characteristics, the students&rsquo / motivation decreased. If teachers exhibited the negative characteristics in a positive way it was likely to increase students&rsquo / motivation. The qualitative part enhanced results of the quantitative part in that it enlightened the way that those characteristics affected students&rsquo / motivation and what would cause if those characteristics were not exhibited or were exhibited negatively.

The purpose of this study was to investigate the prospective teachers&rsquo / knowledge of mistakes held by elementary students in fractions and their proposed strategies to overcome those mistakes. The data were collected from 149 prospective elementary mathematics teachers enrolled in the elementary mathematics education programs from a public university in Central Anatolian Region. Fraction Knowledge Questionnaire was used to accomplish the purpose of the study. The data collection tool included nine open ended questions, and each question had two sub-tasks. In this study, the items in the &ldquo / Fraction Knowledge Questionnaire&rdquo / were analyzed in-depth in order to reach a detailed description of prospective teachers&rsquo / knowledge about students&rsquo / mistakes on fractions. The results of this study revealed that prospective elementary mathematics teachers mostly could identify the students&rsquo / mistakes. However, although prospective teachers could notice the students&rsquo / mistakes, they could give superficial reasons for these mistakes. Furthermore, verbal explanations, using area representation, using real life model, reviewing prior knowledge, teaching standard algorithm, asking guided questions, using simple examples, using counter examples, using drill and practice, making students aware of their mistakes, and increasing students&rsquo / motivation were the suggested strategies by prospective teachers in order to overcome students&rsquo / mistakes in fractions.

This study aimed to investigate a) which type of written feedback (direct feedback or use of error codes) university prep-school EFL students with elementary level of proficiency prefer to receive on their written texts, b) whether or not the (mis)match between students&rsquo / preferences and received feedback affect their level of improvement in writing, and c) to what extent the students&rsquo / previous writing experience affect their preference for the type of written feedback. In order to determine the students&rsquo / preferences for a specific type of feedback and to find out their previous writing experiences, a questionnaire was designed. Moreover, the participants were given two subsequent writing tasks with the purpose of determining the level of improvement in their linguistic accuracy after receiving their (not) preferred type of feedback. The results show that the majority of the students in the preparatory class with Elementary level prefer to receive use of error codes in their written texts / however, giving them what they ask for may not contribute to their improvement as would be expected. Moreover, some conclusions are made as to the relationship between the students&rsquo / previous writing experience and their current practices.

This study investigates the impact of computer games on students&rsquo / motivation. A computer game was created for this study by using Tomb Raider 4 Level Editor. The game covers photosynthesis, vitamins, carbohydrates, proteins and fat subjects of 5th grade science and technology course. Data was collected from 71 5th grade students of three primary schools. Students have played the game until the end of lesson than they were asked to complete The Instructional Materials Motivation Survey (IMMS). The study reveals that gender, weekly computer use and weekly game playing do not affect the impact of educational computer games on students&rsquo / motivation.

This study investigated the students&rsquo / perceptions about a web based course. Their perceptions about course materials, level of communication, online course support, and satisfaction were discussed in this study. In this case study, Information Technology in Education II (CEIT 112), an undergraduate course at the department of Computer Education and Instructional Technology (CEIT), Middle East Technical University (METU) at 2004/2005 spring semester was taken into investigation. Totally 34 1st year CEIT students attended the course in the term and participated to the study. The course was delivered via web based instruction. The data were collected by using a survey instrument at the end of the term and analyzed using descriptive statistical analyzing methods. Frequency distributions for demographic data about the students and the statements evaluating different aspects of the course were obtained. Results showed that students&rsquo / feelings about course materials, online course support, level of communication and satisfaction were neutral. The study results may be used in evaluation of web-based instruction environment for the instructor and the department. They may give clues in order to create an effective learning environment in the future design of the course.

This study analysed the students&rsquo / perceptions about the web based instruction in a blended learning environment. Students&rsquo / perceptions, expectations and comments about their blended learning experiences, course web site and their communication experiences with the instructor were investigated. This case study was conducted within the Information Technology in Education II Course (CEIT 112). This course was delivered for the undergraduate course at the Computer Education and Instructional Technology Department (CEIT), Middle East Technical University, during the 2004-2005 Spring semester. Number of the participants was 25 and all of them were first year CEIT students. This course was delivered as a blended learning which combined face-to-face instruction with the web based instruction. The questionnaire was used to identify the students&rsquo / perceptions about the web based course at the end of the semester. Interviews were conducted at the end of the semester in order to take students&rsquo / comments, expectations and recommendations with respect to the course. Also, an interview was conducted with the instructor to identify his perceptions about the blended instruction experiences at the end of the semester. Both quantitative and qualitative data were gathered at the end of the semester. Data results showed that students had positive perceptions about the blended learning environment and to some extent neutral about the effectiveness of the course website. According to the instructor&rsquo / s point of view, the blended learning was beneficial for the students, but the efficient utilization of computer mediated communication would be better supported. This study can contribute the following research studies related with the blended learning. Also, the instructor of the course can benefit from this research result in order to improve the productivity of the course for the next terms.

This study aimed at investigating the effect of an extended teacher wait time on student participation in primary school context. The main purpose of the study was to inquire whether primary level students would participate in the lesson more when they are given extended wait time after questions than those lessons in which they received average wait time. Students&rsquo / attitudes towards receiving extended wait time and teachers&rsquo / opinions about and experiences in applying it were also explored. For this purpose, two fifth grade classes at ihsan Dogramaci Foundation Bilkent Primary School participated in the study. Pre-test and post-test results and first part of the teacher and student questionnaires provided the quantitative data of the study. The qualitative data came from the second part of the questionnaires that were given to the teachers and the students. The analysis of the quantitative data indicated that students who received extended wait time participated in the lesson more than the students who received average wait time. Analysis of the results of student questionnaire indicated that the students were aware of the positive outcomes of being allowed extended wait time. The results of the teacher questionnaire showed that although extending wait time strategy and its outcomes are known by the teachers, it is not widely used in the classrooms.

This study aims to investigate the preservice teachers&rsquo / perceptions about online communication in blended learning. The study tries to understand strengths and weaknesses of online communication from the learners&rsquo / point of view. To reach this aim, four research questions are asked: (1) What are the learners&rsquo / perceptions about the online synchronous communication tool? (2) What are the learners&rsquo / perceptions about web-based support? (3) What are the learners&rsquo / perceptions about collaboration with online communication? (4) What are the learners&rsquo / perceptions about the roles of the instructor at blended learning as (a) administrator, (b) facilitator, (c) technician, and (d) evaluator? To answer the research questions, a case study in line with action research design was conducted. An undergraduate course in blended learning form was selected as a case and both synchronous and asynchronous communication tools were utilized throughout the semester. At the end of the semester, data about perceptions was collected via four questionnaires and interviews with the students. Both qualitative and quantitative results showed that the online communication facilities in the case were perceived to be adequate by the students. Yet, the students reflected diverse thoughts about preference of communication modalities in synchronous communication. Moreover, the value of asynchronous communication was pointed out. It is concluded that communication needs, communication partner and other contextual factor have impact on selection of communication modalities.

The purpose of this study was to investigate teachers&rsquo / ways of using mathematics textbooks while planning the lesson and during the lesson, to document teachers&rsquo / views about elementary students&rsquo / usage of mathematics textbook during the classroom time and for their homework and teachers&rsquo / views about mathematics textbooks&rsquo / characteristics. A case study was conducted in a private elementary school with more class hours for mathematics and six mathematics teachers teaching 4th, 5th, 6th, and 7th grade mathematics in this school participated. Data were collected in the spring semester of 2010-2011 academic year through an interview protocol with 16 main questions addressing teachers&rsquo / mathematics textbook usage and students&rsquo / mathematics textbook usage developed for this study by the researcher through the findings and discussions in the literature. Data analysis was conducted through qualitative methods. The findings of this study showed that participant teachers expressed both positive and negative views about characteristics of textbook and usage of textbook. All of them stated that the textbook was their main tool for lesson preparations and teaching. They followed the curriculum from textbook and decided what to do, how to do, and when to do. Participants underlined that textbook was an effective helper but it needed improvement in many aspects. The findings also showed that teachers viewed that students did not use their textbook efficiently. All of the teachers expressed that students did not prefer to study from textbook if there were not any assignment or homework. Teachers specified that students could improve studying habits from textbook if teachers could direct them efficiently. The findings of this study might be useful to prepare more effective lessons for teachers, to give ideas to teachers for guiding their students for effective textbook usage, and to increase the quality of textbooks.

The purposes of this study were to explore students&rsquo / perceptions of the extent to which constructivist approaches are present in chemistry classes at high school level in Turkey, to assess students&rsquo / perceptions of their chemistry teachers&rsquo / communication behaviours in their classroom learning environments and to investigate the learning strategies of students in chemistry classes considering school type, gender, and grade level differences. In this study, the Constructivist Learning Environment Questionnaire (CLES), the Teacher Communication Behaviour v Questionnaire (TCBQ) and the Motivated Strategies for Learning Questionnaire (MSLQ) were used as measuring instruments. In addition, the questionnaires included some questions for demographic characteristics of participants. The study was conducted in conveniently selected two schools (private and public) in Ankara with a total of 994 ninth and tenth grade students in the second term of 2006-2007 semesters. Data obtained from the administration of measuring instruments by using the analysis of multivariate analysis of variance (MANOVA) The results of the study indicated that school type, gender and grade level of the students had significant effect on perception of classroom learning environment, teacher&rsquo / communication behaviour and perceived use of learning strategies. For instance, students in private schools perceived their classroom-learning environment more constructivist than student in public school. In addition girls rated that, their learning environment and teachers&rsquo / communication behaviours more favourably than did boys. The study also showed that students use rehearsal-learning strategy mostly in their chemistry classrooms.
