The purpose of this study is to investigate how elementary teachers perceive and practice using Visual Thinking (VT) in science classes. For this, we collected 161 VT teaching materials for science that uploaded on the elementary teacher's online communities, and analyzed the characteristics. Also we interviewed four elementary teachers who have used VT in science class. The results are as follows. First, VT teaching materials shared in teacher's online communities were most often used to review the science concepts that students learned. Most of the materials required 'remember' among the Cognitive Process, and most of them provided layouts for VT activities. Second, the participants were using VT materials to review the science concepts they learned, so that students remember them. Third, the participants were satisfied because of the beliefs of effects as follows: facilitating learning and reviewing what students had learned; increasing students' positive reactions and confidence; learning through the interation among learners; the formation of habits thinking visually; indirect experiences of science class; possibility of class corresponding to learner characteristics. Fourth, the participants had difficulties in preparing for the VT science class, such as the burden of making VT materials, the long preparation time, concerns over overlapping contents, consideration of learners' VT skills, and the themselves' drawing ability. Furthermore, they also had difficulties in proceeding for the class, like different preference among learners about Visualization and loss of objectives in science class using VT. Fifth, the participants needed support as follows: platform to share students' VT results; VT case books and teachers' guidebooks; physical environment.

The purpose of this study was to determine the effects of verbal analogy activities on science achievement and science attitude of elementary students. Students consolidated lessons by making short sentences with core words that a teacher gave for scaffolding instruction. Many researches about analogies have been conducted in science education. However, most of them considered analogy as learning tools, whereas this research considers analogy as a cognitive process. To see the effects of verbal analogy activities, two groups were selected from 6th grade elementary school students; one was an experimental group working with the student-generated verbal analogy and the other was a control group with teacher-centered and textbook-centered activities. Science achievement, scientific attitudes, attitudes toward science and retention were tested after the treated lessons.

The purpose of this research is to analyze teacher's lesson language pattern based on robot class. For this research as an analytical tool AF (Advanced Flanders) was utilized. Actually ClassReport ver 1.0 computer program was used in the process of input data. From the results of the Flanders index, The major instruction sequences were 4-8-3 in elementary school and 4-8 in middle school. The teacher's remarks in robot class in the elementary school rank 'instruction', 'question'. And In the middle school rank 'instruction' and 'positive advice' are very high ratio, but 'indication' is low ratio. The teacher constantly teach and ask question ratio in the middle school was higher than elementary school. But a tendency for non-indication was low ratio in the middle school than elementary school. These results could provide effective cues and information on how to to improve instruction.

본 연구의 목적은 2013-2024학년도 초등임용시험의 수학과 문항을 분석하여 수학 교과를 가르치기 위해 초등학교 교사에게 요구되는 지식과 그 특징을 파악하고 초등임용시험의 개선 방향을 논의하고자 한다. TEDS-M의 분석틀을 수정 및 보완하여 분석한 결과 MCK와 MPCK의 비율이 해마다 차이가 있었지만 전반적으로 MPCK의 비율이 높았다. MCK와 MPCK는 특정 지식 영역, 인지적 과정, 수준에 편중되는 현상을 보이고 있었고 고등 사고력과 평가 지식을 측정하는 문항이 부족하였다. 이러한 결과를 토대로 다변화하고 있는 사회에서 필요한 교사의 지식과 능력을 평가할 수 있는 초등임용시험의 개선 방향을 제언하였다.

This study analyzed the effect of Human-oriented Alternative Science Activities(HASA) on a coaching teacher and the students who participated in this activity. Human-oriented alternative science activities were used in the experimental group and traditional teaching methods were used in the control group. In pretest and posttest sessions, both groups were evaluated using an academic achievement test, and an affective characteristics related science test. After the activity, questionaries regarding attitudes to science lessons were administered as well. The process of change (if any) which occurred in the science lessons of the experimental group teacher was also analyzed through the teacher's diaries. The results showed that application of HASA had a positive effect upon affective characteristics and attitudes to science classes held by the experimental group and teacher. However, the result of this study also showed that the variation between academic achievement of each group was statistically insignificant.

Mathematics educators have examined mathematical modeling, where students tackle authentic real-life problems and develop problem-solving strategies with a sense of agency. However, few empirical studies have been conducted to illuminate the developmental process of teachers' competencies in mathematical modeling, particularly for elementary school teachers. Scholars have noted that elementary mathematics teachers can effectively teach mathematical modeling by designing tasks that consider students' abilities and preferences. In this vein, this review paper introduces a study conducted by Jung (2023), which examines the developmental process of an elementary school mathematics teacher's competencies in mathematical modeling and how she overcame related challenges.

The purpose of this study was to investigate the elementary students' views about lab-based science learning. For the purpose of this study, semi-structured interviews were conducted with thirty sixth grade students in 12 classes from two elementary schools located in Daegu City. The interview contents consisted of three major categories. The first category was related to attitude toward science lab, the second was related to lab-based science learning which had four sub-categories; recognizing lesson object, planning experiment, performing experiment, drawing conclusion in lab-based science learning in which the students had ordinary have views and expectations, and the last category was related to students' difficulties and something need to be improved in lab-based science learning. In-depth interviews were performed individually and the interviews were recorded. From the interviews, we found that students, in first category, do like lab-activities more than lectures or instruction-based activities in textbook. Students, in second category, wanted generally more discussion for their own activities rather than teacher's instruction and they wanted teacher' mediation conflicts within small groups and comments for students' experiment results. In the last, most of students had fears for some dangerous reagents and accidents. Based on the results, the study suggested that teacher need to give their students to autonomous discussion opportunities to design and interpret data through teacher' guided questions in inquiry steps, to produce some intimate atmosphere for active interaction in small groups, and to teach the safety education on some dangerous reagents.
