The crisis of the COVID-19 pandemic has caused significant changes in education systems worldwide, including in Korea. Due to COVID-19's social distancing policies, the education system was suddenly switched to distance learning, resulting in many problems in primary schools without preparation. The purpose of this study was to investigate a teacher's awareness of science education techniques, responses to issues in science classes, including inquiry activities, advantages and disadvantages, and roles after experiencing distance learning. Survey and focus interviews were conducted for primary school teachers who had previously participated in distance learning, such as online content classes and real-time interactive classes. The study findings showed three conclusions: 1) Primary school teachers conducted one-way and interactive lectures in online classes. It is vital to improve a teacher's digital literacy to improve other teaching methods such as investigation and discussion in online classes. 2) Primary school teachers acknowledged the challenges of field feedback, inquiry item preparations, and safety in inquiry activities of science classes, by providing individual experimental packages and videos and using online discussion and feedback among teacher - student and student - student interactions. 3) Primary school teachers recognized that various types of classes using IT devices and individualized learning were possible as advantages of distance learning. As for disadvantages, it was acknowledged that inquiry activities, cooperative learning, immediate feedback, and interaction among students were challenging. Furthermore, learning gaps were wider in distance learning.

The purpose of this study was to find out the validation of instructional strategies using the Advanced Laboratory Equipment (ALE class) by investigating science high school students’ perception on ALE in chemistry classrooms and to consider the need for development of teaching materials on ALE class. 7 sessions of ALE including experiments with innovative equipment were developed and applied to 21 students in D Science High School. At the end of the sessions, questionnaire was given to the students. We also collected qualitative data by interviewing 9 students who participated in the questionnaire. We analyzed the data collected by In-depth interviews and students’ experimental reports. The result showed that ALE class was effective to enhance students’ understanding of learning concepts because the experimental time was shortened in real time data processing. Some students showed creative performance on solving scientific problems by using everyday materials in experimental process and developed perceptions of practical inquiry. Through this process, students’ positive attitudes and interests in science and heuristic inquiry skills were also enhanced. Developing ALE lesson materials will be helpful for students to understand science and technology and the domain of science in broader contexts.

The purpose of this study was to find out the factor that causes the difference on understanding the aim and perception of laboratory activities between teachers and students. For this study, in-depth interview was conducted for sixth grade students and teachers of 10 classes. The questionnaire of the interview can be divided into 3 sections: the aim of laboratory activities, whether teachers present the aim of laboratory activities, the method of laboratory class progress and the evaluation method. The factors that bring about the difference between the teachers and the students on perception of the aim are the absence of proper guidance on the aim of laboratory activities, the laboratory classes that the progress out of teachers' intention and evaluation method that is the performed without any relationship with the aim of the laboratory activities. Because the teacher-intended aim of laboratory activities is not properly presented, students can't percept the accurate aim. Even though teachers recognize the importance of the improvement of science process skill acquired through laboratory activities, this is not delivered practically in the class and students also can't percept the importance of science process skill.

This study investigates the science teacher identity of pre-service science teachers (PSTs) in the context of a teaching practice course. Twenty-two PSTs who took the 'Biological Science Lab. for Inquiry Learning' course at the College of Education participated in this study. Artifacts created during the course were collected, and the teaching practices and reflections were recorded and transcribed. In addition, semi-structured interviews were conducted with nine PSTs, recorded, and transcribed. We found the science teacher identity was not well revealed at the beginning of the course. Authoritative discourse appeared in the early oral reflections of PSTs, indicating that the PSTs perceived oral reflection activities as 'evaluation activities for teaching practice'. This perception shows that pre-service teachers participate in teaching practice courses as students attending a university, performing tasks and receiving evaluations from instructors. After the middle of the course, discourses showing the science teacher identity of the PSTs were observed. In the oral reflection after the middle part, dialogic discourses often arose, showing that the PSTs perceive the oral reflection activities as a 'learning activity for professional development'. In addition, in the second half, discourse appeared to connect and interpret one's experience with the teacher's activity, indicating that the PSTs perceive themselves as teachers at this stage. In addition, the perception of experimental classes was expanded through the course. During the course, the practice of equalizing the authority of the participants, providing a role model for reflection, and experiencing various positions from multiple viewpoints in the class had a positive effect on the formation and continuation of the teacher identity. This study provides implications on the teacher education process for teacher identity formation in PSTs.

The purpose of this study is to develop theme-based integrated science unit by the interdisciplinary approach and to analyze it's effects on the science achievement and the attitude towards science learning. 'Interaction' and 'Stability' were selected as the integrated themes, and the main concept and subconcept in relation to the themes were extracted from the four areas of science, and the learning contents were constructed in the integrated ways. While the main concept have relevance to subconcept in the interaction, the main concept have little relevance to subconcept in the stability. Therefore, the stability was to fit with middle school integrated science theme, but the interaction was not. The theme-based integrated science units developed was implemented in middle school, and the results are follows. First, the science achievement of group of theme-based integrated science teaching is significantly higher than those of group of traditional teaching. Second, the scores of the test of attitude toward science learning of the group of theme-based integrated science teaching is significantly higher than those of group of traditional teaching. Third, the students' perception of theme-based integrated science teaching was positive. The students have participation, interest, motivation in theme-based integrated science teaching, and students have difficulty in learning theme-based integrated science teaching.

The consistency and balance of objectives by objective domains in units, sub-units and instructional units were investigated. The 6th elementary biology curricular teaching guidebooks were analysed. Domains of objectives are cognitive, inquiry process, instrumental skill, creative, affective and STS. Cognitive objectives were most dominant in all units, sub-units and instructional units. But no objective for creative domain were suggested. In unit and sub-unit, proportions of objectives were cognitive, inquiry process, affective, instrumental skill and STS domains in order. Objectives for cognitive and inquiry process domains were more than others in instructional units, Except cognitive and inquiry process domains, objectives for the others were not consistent in all units, sub-units and instructional units. Especially, the percentages of objectives for affective domain decreased in units, sub-units and instructional units orderly. These resulted from teaching objective domains categorized formally, Thus, it is necessary to develope curriculum and textbook to be consistent and balanced with objective domains and reflect upon the characteristics of them.

In the era of the 4^th industrial revolution and convergence, various discussions and studies have been conducted to develop future social talents, and through this, the need for creative convergence talents is increasing. In line with the change to a software-oriented society, countries around the world are trying to strengthen SW education, but high school students' awareness of the necessity of information subject and SW education that is the center of convergence is insufficient. Therefore, opportunities for convergence of the information subject and various fields should be provided. In this study, information education was converged to the science exploration experiment subject to construct an educational program that can develop creative convergence, and a convergence class using physical computing were applied to high school students for 9 hours. As a result of the experiment, the recognition of SW education of the experimental group was improved, and it was confirmed that the learner's convergence literacy of the experimental group was statistically different from that of the control group that conducted the general science experiment class.

Recently, there has been a dramatic increase in the number of cases that have formed and operated teachers' learning communities through cross-curricular consulting at the school level. The purpose of this study is to explore cross-curricular instructional consulting as an activity of teachers' learning communities at the school level, and investigate the effect of cross-curricular instructional consulting on middle school science teaching. We analyzed features and limitations of cross-curricular instructional consulting revealed in three case studies in middle school, including open classes and instructional consulting sessions, and conducted additional instructional consulting on the same videotaped science classes with science experts from outside. According to the results, science inquiry experiments are often replaced with text reading and interpreting, students' misconceptions and exact scientific representations are ignored, and the goal setting as well as class coverage has been questionable and disputable in science classes resulted from cross-curricular instructional consulting. Discussed in the conclusion are the necessity of cross-curricular instructional consulting in middle school, and ways to overcome limitations of the method of cross-curricular instructional consulting, including alternatives to a praise-only policy in cross-curricular instructional consulting, ways to use cross-curricular instructional consulting without compromising the subject's essence, and ways to improve the undue authority of consultants.

Using TIMSS survey data, we analyzed whether there were any significant changes in the learning environment of middle school science classes over the last 10 years. Our study selected questions from teachers and school principals' questionnaires and divided them by category: science class, teacher professional development, and school environment. The science class components were subdivided into three categories: science learning activities, evaluation, and homework. Within teacher professional development, the sub-categories included teacher training, collaboration to improve teaching, and teacher evaluation. School environment subdivided into two aspects, these being school characteristics and school system. Our research confirmed that there has been a positive change overall in learning environments. However, most classes are teacher-conducted and also teacher-oriented; the proportion of science investigation activities has declined compared against the prior ten years. Our study show that students do not engage in a range of inquiry-related activities. The questions on tests and examinations involve mostly knowledge application and understanding, although recent methods of evaluation show improvement. As for the science teachers, they participate in many professional development programs but focus on science content, science curriculum, and pedagogy. In addition, teachers do not have many opportunities to participate in the training to integrate information technology into science, science assessment, or improving students' critical thinking or inquiry skills. The teachers are satisfied with their profession, and the shortage of science resources does not seem to affect instruction.
