The purpose of this research is to investigate the types of semantic errors made by MT in translating EFL college students' original drafts written in Korean into English. Specifically, this study attempts to find out 1) what types of semantic errors are most frequently committed by MT? and 2) how students feel about the quality of the MT-produced output? The findings from this study indicated that MT produced the errors related to accuracy (47%) the most, followed by the errors related to fluency and ambiguity (14.6% respectively). Students were well aware of the errors with accuracy and fluency but had limited ability to check the errors with ambiguity. Based on the findings, this study suggests pedagogical implications which can be implemented in L2 writing classrooms.

The purpose of this paper is to describe about the issues concerning student teachers' perceptions of ICT use and obstacles they experience during the teaching. Student teacher experience conflicts with ICT in particular, and lack of confidence in using ICT. Furthermore, pre-service teachers experience various conflicts while teaching during student teaching. Main conflicts student teachers experience are reported that their lack of confidence in using ICT, especially in front of the student body during the class, and firm belief on ICT and its effects. Student teachers lack systematic training during their professional development. As a conclusion, the teacher training programs need to have systematic approach in their curriculum to assist pre-service teachers to use ICT before their student teaching to give them first hand experience in classrooms.

The majority of research on Automated Writing Evaluation (AWE) programs has focused primarily on Grammarly, whereas QuillBot and its use in English as a Foreign Language (EFL) classrooms remains limitedly explored. This study examined the effectiveness of using QuillBot on the writing quality of college students. A total of 26 participants took pre- and post-writing tests, and four analytical tools were applied to assess their writing quality in terms of syntactic complexity, lexical diversity, lexical richness, and readability. Results of the syntactic complexity analysis across the four indices demonstrates that the syntactic complexity of EFL writing increased significantly, and substantial differences were observed in lexical richness and readability. These results suggest that QuillBot can compensate for the drawbacks of Grammarly and assist EFL writers in improving their overall writing quality.

The purpose of this study is to examine middle school teachers' use of technology and problem-based learning (PBL) in their teaching practice. Factors related to teachers' use of technology and PBL are also investigated including: teachers' computer and Internet skills, feelings of preparedness to use the Internet, attitudes toward the use of web resources, pedagogical beliefs, science teaching efficacy, and the use of general teaching strategies. Twenty-seven middle school science, math, and technology teachers participated in the study. Research results describe the participants as slightly proficient in computer and Internet skills, positive toward use of web resources, and neutral on feelings of preparedness toward use of computer and the Internet. Participants also tended toward constructivist pedagogical beliefs and used various teaching strategies. They, however, reported low science teaching efficacy. Teachers' use of computers and the Internet correlated with pedagogical beliefs and feelings of preparedness toward the use of computers and the Internet. The study also found the relationships between the use of PBL and teachers' computer and internet skills, pedagogical beliefs, and the use of general teaching strategies. Also discussed are meaningful implications for teachers' professional development, especially for the programs designed to facilitate the use of web-enhanced PBL.

This research, selected for 40 classrooms(20 old, 20 new) in chungnam area from June 22 to July 19 and from November 21 to December 30, 2003, in order to study of Recognition of Indoor Air Quality of Indoor Environment at School. we used Questionnaire for 193 health teachers, 41 teachers, and 1,359 students. The results of study are as follows. 1. To the question 'Currently Were you damage caused by classroom air?', showed that worry class teachers more than students with 43.9% of class teachers, 35.9% of health teachers and 23.5% of students. 2. To the question 'What would be an efficient way to manage classroom sanitation?', 50% of class teachers, 40.5% of health teachers and 47.4% of students wanted 'installation of air purifier.' 3. To the question 'How are you getting information about indoor air pollution?', showed that all of 3 groups get information through on TV. 4. According to survey, Health teachers who act as health supervisors appeared to have more prior knowledge air quality than class teachers and students. The results of this research show insufficient understanding of health risks from indoor air pollution, and shows possible health problems to students from school indoor air pollution. Therefore, these results suggested that a logical and systematic education program for students about the importance of indoor air quality should be carried out.

This paper presents an analysis of the Developmental Approaches in Science, Health and Technology (DASH) program, a K-6 curriculum developed by the Curriculum Research & Development Group (CRDG) at the University of Hawaii employing the curriculum analysis framework created by Posner. Using this framework the analyst found that the DASH design is based on the research on learning, teaching, and assessment now driving efforts to reform science education at the elementary level. DASH embraces the constructivist idea that learning is a personal and social process and the recapitulation model that new concepts are built out of theories previously learned. DASH provides an understandable, exciting, and memorable experience in the operations of science, health, and technology, and develops their capacity to use the skills and knowledge of science, health, and technology both in and outside school. A number of studies of DASH have examined its functionality, effectiveness of pedagogy and what students learn. The innovative nature of DASH necessitated a multidimensional assessment that included both quantitative and qualitative research techniques. Ongoing development of the DASH program in the research setting of a university laboratory school permits ever deeper connections with emerging curriculum theory and curriculum practice, and allows new linkages as ideas are tested in research classrooms.

Information technology is sometimes considered as a cause that puts education in a big crisis, or it can be seen as a savior. In 2011, the Korean government announced that it would innovate education and build a talented nation by bringing IT into schools of public education system through the SMART education policy. The policy initiative aimed to establish a standard classroom models that can be diffused all over the country's schools so that teachers and students may become familiar of using devices such as tablet PCs and laptops. This paper analyzes how the smart classrooms caused friction in the actual education practices. To this end, I analyzed the direction and ideals of the SMART education policy by reading government policy document and design guidelines officially published, and visited three elementary schools that are actually building and operating a smart classroom environment to visit the facilities and have in-depth interviews with teachers and technicians. The ideal type of classroom proposed by the smart education policy was a package equipped with various functions at once in a neatly designed space like a "model house", but it was difficult to be used as a normal classroom in everyday life of school. Instead of copying and installing the model, each school decided to get "smart" in its own way, depending on how factors such as size, local characteristics, socioeconomic conditions of students and teachers, teacher experiences, and the level of existing infrastructure were combined. In Elementary School A, the machines tamed specific space of the school to create their own space, while following the rules of the school for being mobile. Although Elementary School B could not construct fully supported environment that encompassed the entire school, the system was organized with the help of well trained teacher's experiences in other schools. In Elementary School C, the machines are concentrated on specific classrooms and they promote teacher's professionalism. The components of the smart classroom were disassembled and recombined in context to make each school's classroom "smart".

An educational network system based on CAN protocol internal to a passenger ground vehicle has been developed. The developed network system has been applied to a commercial plug-in electrical vehicle and verified the educational applicability. To apply this in-vehicle network technology based on CAN, a suitable electric vehicle has been chosen and a CAN network structure has been designed, developed and manufactured. Since the commercial electric vehicle chosen as a test bed has its own proprietary electric network, we explain how the original electric network has been utilized and how the new network system has been designed. The developed network system on a real vehicle has been tested to show the applicability and the performance. Finally, the system has been applied at few classrooms to demonstrate how the in-vehicle network system works and to teach how to analyse the CAN signals. The developed system proven to be effective for educational purpose.

Using computer technology in teaching school mathematics creates new instructional environments. The emphases on the use of computer technology in the classrooms and in particular the use of computer-based exploration as a context of mathematics instruction have been reflected in the recommendation of the NCTM (Curriculum and Evaluation Standards for School Mathematics, 1989). Although the power of using computer technology in the exploration of mathematical problems has been recognized and stressed by many educators, we do not have many research studies on mathematics in computer-based explorations. Especially research has failed to clarify how computer technology can contribute to the construction of procedural and conceptual knowledge of mathematics. Up to now most researches on procedural and conceptual knowledge in computer environments have only focused on classifying programming languages which program language has more random access and rich interrelationship characteristic in relation to conceptual knowledge in humans, and which computer language has more characteristic flavor of procedural knowledge. How computer-based explorations affect the knowledge construction of mathematics, therefore, emerges as an issue of research on teacher education program for theoretical framework. This situation leads to do research on the effectiveness of using computer explorations in pre-service teacher education in terms of procedural and conceptual knowledge construction.

Videoconferencing technology is increasingly used in classrooms to introduce children to people from other countries and cultures in order to provide a wider learning experience. However, with traditional screen-based video conferencing technology, research has shown that it is easy for students to miss non-verbal cues that play a key role in developing human relationships. To investigate how children interact differently when their interactions are mediated through screen-based video communication versus robot-mediated communication, we conducted a study with elementary students in Korea, comparing the use of both technologies to introduce classroom students with peer-aged individuals in America. Our findings show that the children displayed more positive emotions during certain tasks and exhibited more interest and intimacy to remote participants in the context of robot-mediated communication than with video-mediated communication.
