Instructive lessons in the language classrooms are extremely constrictive to language learners in improving their English skills, thus, the use of technology in education plays an important role in a language classroom. Results of language proficiency improvement of the learners vary depending on the extent of supplementary materials offered by the internet delivered to the learners. The purpose of the present study is to explore and propose a new approach of language acquisition offered by the internet. This study presents effective methods of using the internet in carrying out the written work. In this paper, we show that the relationship between participation of the learners in the class activities and improvement of English writing skills are mutually proportional.

The necessity of this study was to improve academic achievement and math attitudes through leveled reciprocal peer learning, and the specific purpose was as follows. First, each unit seeks to select learning methods and contents for each level of class for reciprocal peer learning, second, develop activity sites for each level through curriculum analysis, and third, improve academic achievement and math attitudes through classes that apply reciprocal peer learning activities. The study was conducted on 60 second graders of 00 High School in 00 Metropolitan City. Two classes were selected for the midterm exam results for the first semester of the second grade. Class 1 was divided into the experimental group and the other class 1 was divided into the comparative group, and 13 classes were conducted for about 2 months from May 1 to July 4, 2020. The experimental group (30 students) was a class that applied leveled reciprocal peer learning activities, and the comparative group (30 students) was a class that was taught based on traditional textbooks. As a result of this study, first, in this study, it was possible to improve academic achievement and math attitudes by setting learning contents for each unit and applying reciprocal peer learning activities for each level. Second, the experimental group taught by applying leveled reciprocal peer learning activities was effective in academic achievement and math attitudes compared to the comparative group taught based on traditional textbooks to students in the upper, middle, and lower groups. Third, in the class applying leveled reciprocal peer learning activities, low-level students who were neglected in math classes were also interested in the class and actively participated in it, showing improvement.

This study introduces a development of calculus contents which makes to understand the main concepts of calculus in a short period of time and to enhance problem solving and computational thinking for complex problems encountered in the real world for college freshmen with diverse backgrounds. As a concrete measure, we developed 'Teaching and Learning' contents and Python-based code for Calculus I and II which was used in actual classroom. In other words, the entire process of teaching and learning, action plan, and evaluation method for calculus class with Python based coding are reported and shared. In anytime and anywhere, our students were able to freely practice and effectively exercise calculus problems. By using the given code, students could gain meaningful understanding of calculus contents and were able to expand their computational thinking skills. In addition, we share a way that it motivated student activities, and evaluated students fairly based on data which they generated, but still instructor's work load is less than before. Therefore, it can be a teaching and learning model for college mathematics which shows a possibility to cover calculus concepts and computational thinking at once in a innovative way for the 21st century.

As information technology has been developed in a rapid way, a lot of users get to be familiar with social media. Accordingly, the possibility of social media for educational use has increased. From the view point of learning, social media help learners make communities of practice that can lead to collective intelligence. In this study, two different types of social media, synchronous and asynchronous, were compared in terms of usage patterns in the e-learning settings of college level. Content analysis has figured out four factors: learning content, tasks and assignments, emotional communications, and chatting. There found to be a statistical differences in the postings in all of the factors except tasks and assignments. In the qualitative interviews, the participants told various usage patterns of synchronous and asynchronous social media. In sum, the learners generally preferred synchronous social media. Rather, asynchronous social media were mainly used for deep thinking and summarizing. Last, suggestions were made to improve educational environments for the learners in the digital and social media age.

This article is to investigate the possibility that project-based classes introducing mobile phones can replace the monotony of traditional classes led by teachers as well as they can encourage students to take active part in the classes to some extent. The students in groups choose a genre for their own video projects (e.g., movie, drama, news, documentary, and commercial) and produce the video contents using a mobile phone for presentation made at the end of a semester. In the sense that the students are allowed to do video-based mobile phone projects, they can work independently outside of class, where time and space are more flexible and students are free from the anxiety of speaking or acting in front of an audience. A mobile phone project consists of around five stages done both in and outside of the classroom. All of these stages can be graded independently, including genre selection, drafting of scripts, peer review and revision, rehearsals, and presentation of the video. Feedback is given to students. After the presentation, students filled out a survey questionnaire sheet devised to analyze students' responses toward preferences and level of difficulty of the project activity. Finally, proposals are made for introduction of a better mobile phone-based project classes.

SCORM(Sharable Content Object Reference Model)은 세계 이러닝(e-Learning) 표준화 분야에서 가장 주목을 받고 있는 ADL(Advanced Distributed Learning)의 표준화 모델이다. ADL은 비교적 안정화 단계에 접어들었다는 평가를 받고 있는 SCORM 2004를 제시함으로써 콘텐츠의 재활용성을 높여 경제성 있는 콘텐츠 구현을 가능하게 하였고, 개발 과정에서의 효율성을 극대화 시켰다. 그러나 SCORM 스펙의 다양한 요소를 충분히 활용하면서도 게임적인 요소를 가미하여 효과적인 학습 콘텐츠를 구현 할 수 있는가에 대한 연구는 현재 매우 미약한 실정이다. 또한 IMS SS(Simple Sequencing)를 기반으로 하는 SCORM 시퀀싱 & 네비게이션은 구현 방법이 간단하지 않아 LSAL등에서 제공하는 SCORM 시퀀싱 템플릿을 거의 그대로 사용하는 것이 일반적이다. 따라서 본 연구에서는 LSAL 템플릿 모델 및 게임 기반 학습에 대한 관련 연구 조사를 수행하고, 게임 기반 학습에서 사용 될 수 있는 SCORM 데이터 모델을 참고하여 이를 실제 초등 학습에서 적용 가능한 SCORM 기반 에듀테인먼트 콘텐츠를 제작한다. 또한 기존의 선형적인 학습 구조에서 벗어나 수준별 학습을 실현하는 보다 구체적이고 세련된 시퀀싱 & 네비게이션 설계 방법을 제시한다.
