본 연구는 수열에 대한 학생의 두 가지 인식을 바탕으로 고등학교 수열 수업에서 나타나는 학생의 수학 주목하기를 분석하였다. 구체적으로 수학 주목하기를 초점의 중심, 초점을 유발하는 상호작용, 수학 과제의 특징, 수학 활동의 본질의 네 가지 측면에서 분석하여 다음의 결과를 얻었다. 우선 초점의 중심 변화 양상은 '초점을 유발하는 상호작용', '물질적 자원', '수학 활동의 본질' 중 어떤 한 구성요소만으로는 유일하게 묘사될 수 없었다. 다음으로 수학 주목하기 구성요소 간의 상호작용이 식별되었으며, 소집단 활동에서의 교사의 개별 피드백은 초점의 중심 형성에 영향을 주었다. 마지막으로 학생들은 동일 교실, 즉 동일 초점을 유발하는 상호작용, 물질적 자원, 수학 활동의 본질 내에서도 서로 다른 두 가지 추론 양상을 보였다. 본 연구가 마중물이 되어 수열에 대한 학생의 이해 연구가 더욱 활발히 진행되길 기대한다.

본 연구는 우리나라 고등학교 학생들(142개 학교의 4863명)의 PISA 2015 컴퓨터 기반의 협력적 문제해결력(Collaborative Problem Solving, 이하 CPS)에 미치는 학생, 학교 수준의 배경요소와 ICT 요인을 설정하여, 설명 변수가 없는 기초모형(모형1)부터 모든 변수가 투입된 최종모형(모형5)까지 2수준 위계선형모형(Two-Level Hierarchical Linear Model, 이하 HLM)으로 분석하였다. 연구 결과 첫째, 성별, 사회경제문화적 배경, 협동지수는 CPS 점수를 정적으로 예측하였던 반면 학생들이 지각하는 교사의 불공평함은 CPS 점수를 부적으로 예측하였다. 둘째, 학교 밖에서 이루어지는 학습 목적의 ICT 사용빈도가 많을수록, 그리고 오락 목적의 ICT 사용빈도와 학교에서의 ICT 사용빈도가 적을수록 CPS 점수가 높았다. PISA 2015에서 최초로 측정된 ICT 태도 중 ICT에 대한 흥미가 높고 ICT 기기 사용에 대한 자율성이 높을수록 CPS 점수가 높았으며, ICT를 사회적 상호작용(SNS, 채팅)을 위한 도구로 더 중요하게 인식하고 있는 경우에는 CPS 점수가 낮았다. 셋째, 학교 수준 변수에서는 학교의 학습 분위기를 저해하는 학생 행동이 적을수록, 교사 근무환경 만족도가 높을수록, 그리고 학생 당 이용가능한 컴퓨터 수가 적을수록 CPS 점수가 높았다. 결론적으로 컴퓨터 기반의 협력적 문제해결력 소양을 높이기 위해서는 학생들이 ICT에 대한 흥미나 자율성을 가질 수 있도록 조력해야 하며, 학교현장의 ICT 기기의 효과성을 높이기 위한 ICT 활용이나 SW 교육과정에 대한 지침이 마련되어야 할 것이다.

이 연구에서는 과학 영재를 위한 토론수업을 위해 새로운 FPHER (problem finding, prediction & discussion, hands-on & experiment, explanation & arrangement, enrichment) 수업 모형을 개발하고, 이를 적용하는 과정에서 나타나는 언어적 상호작용의 특징을 분석하여, 수업 과정에서 나타난 언어적 상호작용의 전반적인 특징 및 수업단계별 특징을 알아보았다. 연구를 위해 과학고등학교 1학년 화학수업 시간을 이용하여 학생들에게 수업 처치를 하였으며, 각 모둠별로 학생들의 토론 내용을 녹음하고, 분석하였다. 연구 결과, 개발된 FPHER 수업 모형은 대부분 과제와 관련된 인지적 영역의 상호작용을 유도하였으나, 의견받기 보다는 의견제시가 우세하였다. F 단계에서 전반적으로 상호작용이 적었고, P 단계에서는 과제해결 관련 제안과 자신감 부족이 많았다. H 단계에서는 과제진행 관련제안이 많고 지시가 많았다. E 단계에서는 질문과 설명, 불만과 자신감 부족이 많았다. R 단계는 상위수준 상호작용을 유도하였으며, 주로 활동지와 상호작용을 하며 상당히 수준 높은 문제 해결력을 보였다. 앞으로 FPHER 수업 모형에 따른 학생-학생 간 상호작용과 교사가 학생의 설명에 반론을 제기하거나 정교화나 정당화를 요구함으로써 사고를 유도하는 형태의 수업에 익숙해 질 수 있도록 교사와 학생 간의 상호작용이 활발할 수 있는 수업전략의 심층적인 연구가 필요하다.

This study was to find the difficulties students faced in their mathematical learning and to identify the instructional dimensions a teacher provided for the students from multi-cultural background. Since the study was focused on the process of students' learning, the qualitative method was chosen through clinical interviews with 2 students in a total of 11 units which played a role of compensating their learning of mathematics as an extra curriculum. The students solved the computational problems relying on formal procedure without understanding of concepts and principles and solved the word problems based on own interpretation of certain words without semantic comprehension out of math sentences. As the instructional dimensions of teaching mathematics, tasks, a tool and classroom norm were found in the activities they performed. For the tasks, situated tasks, challenging tasks, tasks with lack of conditions, and open-ended exploratory tasks were used. As the tool, pictorial representations were very useful to describe their ideas. Finally, as the classroom norm, consider equity for everyone, and cooperate and encourage each other were found.

It is the concept of this paper to build up the convergence type of the total class service system, and the goal is to develop the education services, which are differentiated from existing digital textbooks and development tools. We establish developmental programs and convergence strategies from market analyses related to apps and digital education. Then this paper proposes 'E-Class Author Service System (ECA)' as an education service system based on the tablet PC. It is the convergence system of the app type of textbook development tool and class management system. Teachers can produce and develop class materials and textbooks using the app type of textbook development tool in ECA service system. They can also add necessary functions from the class management system for efficient class progress. ECA improves the interaction and communication between a teacher, student and parents in the sever-based network. This study expects that ECA will achieve prior occupation of the app market as an educational app development tool and reduce private education expenses.

This is a case study that defined collaborative utterances and analyzed how they appear in the problem-solving process when 5th-grade students solved problems in groups. As a result, collaborative utterances consist of an interchange type and a deliver type and the interchange type is comprised of two process: the verification process and the modification process. Also, in groups where interchange type collaborative utterances were generated actively and students could reach an agreement easily, students applied the teacher's help to their problem-solving process right after it was provided and could solve problems even though they had some mathematics errors. In interchange-type collaborative utterances, each student's participation varies with their individual achievement. In deliver-type collaborative utterances, students who solved problems by themselves participated dominantly. The conclusions of this paper are as follows. First, interchange-type collaborative utterances fostered students' active participation and accelerated students' arguments. Second, interchange-type collaborative utterances positively influenced the problem-solving process and it is necessary to provide problems that consider students' achievement in each group. Third, groups should be comprised of students whose individual achievements are similar because students' participation in collaborative utterances varies with their achievement.

The aim of this study is to examine the effects of web-based cyber instruction on EFL learning from the viewpoint of learners` perceptions and needs. Data was collected through a questionnaire survey that was carried out with 709 undergraduate student enrolled in three cyber English courses offered at N university during the secind semester in 2004. The results of the study indicated that the learners exhibited a positive attitude towards web-based cyber instruction and considered it a paper educational method in the cyber age. However, the students perceived that web-based cyber instruction was not greatly satisfactory in terms of cultivating their English communicative competence or improving the language skills they needed. It was also found that cyber instruction was still teacher-dominant, lacking in interaction, which made the students passive recipients of informaton presented. In comparison with off-line instruction, cyber instruction was not particularly better in enhancing their motivation interest or concentration on class. To be more effective, cyber instruction needs to be equipped not only with a large variety of contents and class activities, but also with more exposure to authentic language by native English speakers. The finding of the investigation yield some implications for the design and development of web-based cyber EFL programs.

The development of mobile devices and network technology is changing the ways in which people communicate with one another. Mobile text message has emerged as one of the most frequently used form of communication, which also gave rise to various non-verbal texts such as emoticons. Nonetheless, the use of text messages has largely been denied in education because text messages often involve colloquial and non-verbal texts considered inappropriate or grammatically incorrect by the teacher. In efforts to provide a theoretical framework to better understand mobile e-text communication, this research compared the practical usages of non-verbal texts in the mobile e-learning environment. The study developed three types of text messages according to the degree of using non-verbal texts and their phraseology as instructors' messages, which were then distributed to 259 students via mobile text messaging. The perceptions of students were analyzed using a semantic differential scale and a questionnaire. The results showed clear differences in students' perceptions of non-verbal text and traditional text, and that optimally designed non-verbal texts turned out to encourage the students' interaction the most out of the three types of text messages. Following the discussion of the results, an expanded theoretical framework beyond Ong's concepts of orality and literacy is also suggested to understand the evolution of mobile e-text communication in education.

Those students with ability and interest in science should be supported to develop their potential and to reach high levels of achievement in science and technology. In order to ensure that gifted pupils are able to enhance their creativity as well as research abilities, appropriate learning programs and environments are essential. One of the various teaching and learning models for the gifted in science is the discovery learning model based on inductive science activities. There is a clear line of continuity between knowledge discovery at the forefront of research and student's learning activities. If students receive excellent training in organizing scientific concepts for themselves, they will be able to skillfully apply appropriate scientific concepts and solve problems when facing unfamiliar situations. It is very important to offer an appropriate learning environment to maximize the learning effect whilst, at the same time, understanding individual student's characteristics. In this study, the authors took great pains to research effective learning environments for gifted science students. Firstly, appropriate classroom learning environments thought by the teacher to offer the most potential were investigated. 3 different classes in which a revised teaching and learning environment was applied in sequence were examined. Inquiries were conducted into students' activities and achievement through observation, interviews, and examination of students' worksheets. A Science Education expert and 5 elementary school teachers specializing in gifted education also observed the class to examine the specific character of gifted science students. A number of suggestions in discovery learning classes for elementary students gifted in science are possible; 1) Readiness is essential in attitudes related to the inquiry. 2) The interaction between students should be developed. A permissive atmosphere is needed in small group activities. 3) Students require training in listening to others. In a whole class discussion, a permissive atmosphere needs to be restricted somewhat in order to promote full and inclusive discussion. 4) Students should have a chance to practice induction and abduction methods in solving problems.
