This study qualitatively examined the lives of non-tenured, secondary school teachers who are preparing for the teachers' exam. Semi-structured, face-to-face interviews were conducted with ten teachers and the data were analyzed using the consensual qualitative research method. Most of the participants had chosen a contract-based teaching position, believing that it would meet their financial needs, provide them with the satisfaction of being a teacher and, more importantly, afford practical help with their exam preparation. In practice, however, they suffered from low self-esteem and identity confusion due to discrimination by the school administrators. Ironically, this unfair treatment strengthened the participants' commitment to studying for the exam, in order to acquire a stable and secure position in school. However, they experienced a lot of study-related stress, including a lack of study hours, heavy study load, multiple life roles, physical exhaustion, the difficulties caused by the vague exam guide, and anxiety due to previous failure in the exam. Based on the findings of this study, directions for future research are suggested.

This study investigated Korean science teachers' concerns and needs regarding inquiry testing to cope with the innovation called College Scholastic Abilities Test(CSAT), which was officially first administered as the nation-wide college entrance exam in 1994. This study adopted Concerns Based Adoption Model(CBAM) as the theoretical framework developed by Hall et al. 60 high science teachers (30 physics, 20 earth science, 10 others) were involved for the main study in August, 1992. In general. science teachers demonstrated a concern profile similar to that of 'nonusers'. They showed high level of concerns on the 'information' and 'personal' stage, while low level of concerns on 'management' and 'consequence' stage. Science teachers expressed their strong needs for knowledge and support to facilitate inquiry teaching and testing, text books written in inquiry mode. It is recommended that in-service trainings be provided based on the concerns and needs of teachers for a better teacher training and successful implementation of the innovation.

Usually, students write on a paper using writing materials and submit it to teachers when they do a homework or take an exam. However, there are temporal and spacial constraints because teachers and students should be in the same place at the time in this system. In addition, it is hard for teachers to maintain numerous papers from students. Applying a digital pen produced by Pen Generations Corporation to education system, we developed a smart education system transmitting image data from written papers using digital pen. As a result, teachers and students can use this system without any constraints. In addition, teachers are able to maintain their papers from students more effectively.

The informatics computer teacher appointment examination is the only national test to measure the competence of educators in teaching students relevant informatics content. The purpose of this study is to provide suggestions and directions for improvement of the informatics computer teacher appointment exam. To this end, we collected appointment exam questions from 2002, when the informatics computer teacher appointment exam first started, to 2017. Based on evaluation areas and evaluation content factors of the indication subject of informatics computer, we built the analysis framework and criteria used in this study. The analysis took into account the revision of basic required courses and changes in the types of exam questions. We analyzed the percentage of points allotted to the subject matter compared to the total number of points, and also the trends of exam questions by school year. The results of the analysis are as follows: first, improvements should be made to avoid concentration in certain areas of the basic required courses of the informatics computer subject. Second, the discrepancy between the exam and the curriculum of basic required courses must be addressed to properly teach and evaluate preliminary teachers. It is significant that this study serves as a stepping stone in supplying highly competent teachers to the field through improving the informatics computer teacher appointment examination.

The purpose of this study is to analyze and present keywords, trends, and language networks of keywords for each year of the pedagogical exam of the secondary teacher's employment exam for the 2019~2022 school year. The main research methods were text mining technique and language network analysis method, and analysis programs were KrKwic, Wordcloud Maker, Ucinet6, NetDraw, etc. The research results are as follows; First, keywords such as teacher, student, curriculum, class, and evaluation appeared in the top rankings, and keywords (online, wiki, discussion ceremony, information, etc.) that reflect the recent online class progress in the current COVID-19 situation also tended to appear. The keywords with high frequency of occurrence in the four-year integrated text were student(44), teacher(39), class(27), school(18), curriculum(16), online(10), and discussion method(8). Second, the overall language network of the keywords with high frequency of 4 years showed a significant level of density(0.566), total number of links(492), and average degree of links(16.4). The degree centrality was found in the order of teacher(199.0), class(197.0), student(185.0), and school(150.0). Betweenness centrality was found in the order of teacher(30.859), class(18.956), student(16.054), and school (15.745). It is expected that the results of this study will serve as data to be considered for preparatory teachers, institutions and related persons, and teachers and administrators of secondary school teacher training institutions.

As computational thinking(CT) is gaining focus as a key 21st century skill much attention has been paid to promoting CT through software education. However, more studies are needed to design and implement effective CT assessment methods. This study aims to investigate the effects of three CT assessment methods in a course designed to enhance CT competencies of 52 pre-service teachers with a non-computer science background during one semester. To analyze pre-service teachers' CT competencies, we used 3 CT assessment methods: (1) pre-and post-testing based on Bebras computational thinking challenge questions, (2) Dr. Scratch to analyze group scratch projects automatically, and (3) scratch exam designed in this study to evaluate the development of CT. Our results show the positive effects of integrating assessment methods for promoting CT competencies. We end this paper with the discussion of advantages and implications of this integration.

Mathematics teachers' content knowledge is an important asset for effective teaching. To enhance this asset, teacher's knowledge is required to be diagnosed and developed. In this study, we employed problem-posing and problem-solving tasks to diagnose preservice teachers' understanding of fraction multiplication. We recruited 41 elementary preservice teachers who were taking elementary mathematics methods courses in Korea and the United States and gave the tasks in their final exam. The collected data was analyzed in terms of interpreting, understanding, model, and representing of fraction multiplication. The results of the study show that preservice teachers tended to interpret (fraction)×(fraction) more correctly than (whole number)×(fraction). Especially, all US preservice teachers reversed the meanings of the fraction multiplier as well as the whole number multiplicand. In addition, preservice teachers frequently used 'part of part' for posing problems and solving posed problems for (fraction)×(fraction) problems. While preservice teachers preferred to a area model to solve (fraction)×(fraction) problems, many Korean preservice teachers selected a length model for (whole number)×(fraction). Lastly, preservice teachers showed their ability to make a conceptual connection between their models and the process of fraction multiplication. This study provided specific implications for preservice teacher education in relation to the meaning of fraction multiplication, visual representations, and the purposes of using representations.

This study aims to investigate how secondary mathematics teachers understand and intend to use textbooks for their mathematics instruction. For this purpose, we developed a set of survey items in order to unpack what the teachers understand the mathematical tasks suggested in the textbooks in terms of the levels of cognitive demand and how they intended to use the tasks in the textbooks for their teaching. Twenty-five teachers participated in the survey. The data from the survey were analyzed. The findings from the data analysis suggested as follows: a) the teachers seemed to closely follow textbooks without attempting to modify the tasks, even when the teachers consider it is necessary to modify textbook tasks to high-level tasks, b) the teachers seemed to be unstable in regards that they admitted themselves very competent for modifying tasks for developing students' mathematical thinking but, at the same time, they were uncomfortable with transforming tasks into cognitively demanding tasks that promote students' mathematical understanding, and c) the teachers appeared to consider textbooks as significant criteria in conducting tests including midterm and final exam. In conclusion, the teachers seemed to intend to follow closely the contents and sequence of mathematics textbooks in their mathematics classrooms.
