Through quantitative analysis of two math classroom videos, combined with the relationship between types of teachers' questioning and students' answering, it is concluded the following problems are in the mathematics classroom teaching: (1) The time of teachers' questioning is longer, the number is too much, with managerial questions and prompting questions is given priority to; (2) Teachers' questioning time is longer than students' answering time, comprehensive answer is more, creative answer is little; (3) In the classroom questioning, students' participation is low; and (4) There is a significant correlation between types of teachers' questioning and length of waiting time after questions. In response to these phenomena, we propose strategies as follows: pursuit of timeliness of classroom questioning, reducing inefficient questions, to increase efficient questions, adopting different waiting strategies for different questioning types, to mobilize students' thinking activities, and improving students' participation etc.

This study explored how teachers and students in different countries discursively interact to build 'Classroom Science Knowledge' (CSK) - the knowledge generated situatedly in the context of the science classroom. Data came from publicly released $8^{th}$ grade science classroom videos of five nations who participated in the Third TIMSS (Trend in International Mathematics and Science Study) video study. A total of ten video-recorded science lessons and their verbatim transcripts were selected and analyzed using a framework developed by the researchers of the study. It was revealed that a range of discourse modes were utilized and these modes were often sequentially connected to build CSK in the science classrooms. Although dominant discourse modes and their sequences varied among different lessons or different countries, the study identified three salient patterns of science classroom discourse: teacher-guided negotiation and the sequences of exploring - building on the shared and retrieving - elaborating. These patterns were found to be different from the discursive features commonly witnessed in the community of professional scientists and interpreted as implying the existence of unique epistemic cultures shared in science classrooms of different countries. Further studies are suggested to reveal detailed characteristics of these epistemic cultures of science classrooms, as well as to confirm whether any cultural traits inherently shape the differences in science classroom discourse among different nations.

This endeavor is an attempt to explore the effect of flipped classroom strategy (FCS) on (a) academic achievement in the computer and information technology course and (b) students' attitudes towards this strategy. The sample of the study consisted of 64 students, divided into two groups: experimental and control groups. Two instruments were used to collect the data: a test and a questionnaire. The test was used to measure the students' achievement and the questionnaire to measure their attitudes towards the FCS. The results show statistically significant differences at the level of 0.05 in support of the experimental group at all Bloom's levels. Similarly, students' positive attitude towards the FCS was evident. Therefore, expanding this strategy in different courses is highly recommended because it positively impacts students' achievements. Organizing workshops and designing courses that encourage teachers to implement the strategy in the classroom and develop their technical skills are also recommended.

The purpose of this study is to reveal the insights that teachers has learned through developing preschooler's classroom into field-trip-oriented ones with role play areas. The data of this study was collected from participatory observation and in-depth interviews, which included videos, photos, teachers' journal, descriptive questionnaire, and interview records. The whole process of organizing role-play oriented class was composed of four steps: activities before the trip, activities on-the-spot, activities after the trip, and its evaluation. Firstly, activities before the trip were making the lists of questions, deciding children who ask the questions, making rules on the trip, understanding the purpose of the trip. Secondly, on-the-spot activities included having a tour of the place and asking the questions. Thirdly, activities after the trip was constructing the classroom into small real world with various sections. This required the teachers to reflect the field trips, make plans how to construct, prepare for the data, and furnish the classroom with role-play areas. In the process of furnishing the classroom with small real world, the field trips played a big role as the learning opportunities for language development, and keeping public rules.

By using the recording and quantitative analysis of two videos about "The multiplication and division of the Fractions" and the "Flanders Interaction Analysis System," we classified the teachers' language of instruction in algebra classroom and also analysis the language of instruction in the different teaching process. The results after the analysis as follows: (1) The proportion of time was taken in teachers' language of instruction is high and vary in types, most of the teachers' language is teachers' question; (2) In the different teaching process, the proportion of time was taken in teachers' language of instruction is different; (3) Teachers attached importance to explain the example and had the similar teaching strategy, but the teachers' language is different; (4) In the practice process, teachers placed importance on exploring the tough question and its teaching strategies are different. The teachers' questions are the main teachers' language of instruction.

Recently, an advanced form of blended learning, which incorporates a teaching method that focuses on flipped learning is actively used in colleges. Flipped learning is for learners to pre-learn content through videos uploaded by instructors before class, and then participate in learner-centered learning activities such as discussions and team activities in the classroom. The purpose of this paper is to review where flipped learning is being used in medical schools, and to draw implications for effective and efficient use in medical schools. For this, the definition of flipped learning, how it evolved, educational usefulness of this method of learning, and application cases in medical schools were reviewed. Through the reviews of cases of flipped learning and its positive effects, it is suggested that medical schools consider more use of flipped learning in the classroom instructions, with sensitivity to the individual medical departments' needs, environment and professors' preferences.

Problem-based learning (PBL) appears to be a superior and effective strategy to train competent and skilled practitioners and to promote long-term retention of knowledge and skills acquired during the learning experience. This study concerns the implementation of PBL in the online environment and face-to-face PBL. An online environment allows participants to communicate with one another, view presentations or videos, interact with other participants, and engage with resources in work groups. Nowadays, education is accessible everywhere with the use of digital devices. Educational institutions subscribe to GSuite for Education, and Google introduced its Google Classroom as an e-learning platform. This study aims to analyze Google Classroom and to design PBL for Mongolian students taking Korean courses. The main objective of this paper is to identify the usability and evaluation of Google Classroom. The result of this study will be a proposed e-learning platform for Dornod University, Mongolia, which is initially needed in the Natural Science and Business Department.

The purpose of this study was to help teachers for their teaching practice by analyzing the excellent lesson videos. To analyze the lesson videos between teacher and students, the researchers classified excellent lesson classes into four types as 'Discourse type', 'Representation type', 'Operation type' and 'Complex type' by mathematical communication pattern and kept close watch each lesson videos. Mathematical communication of the best discourse type classroom was analyzed in terms of questioning, explaining, and the sources of mathematical ideas. As a result, the number of Discourse type classes was 6. Operation type classes were 16 owing to characteristic of elementary class. Representation type class was 1 and Complex type class was 1. The Classes excluding Operation type was more planned by teachers. Teachers need to know about mathematical communication accurately because they designed just 5 lesson plan considering mathematical communication of students and only one of the lessons has the intellectual purpose of communication. Furthermore teachers should reflect questioning for student-to-student in their lesson plan.
