Distance learning for students with intellectual disabilities can prove beneficial, particularly if adjusted to their educational characteristics and needs. This study seeks to identify the views of parents living in Saudi Arabia, regarding the opportunities offered by distance learning for students with intellectual disabilities, alongside their challenges during the Covid-19 pandemic. The research employed qualitative methods using semi-structured interviews with six parents of students with intellectual disabilities. The results revealed a number of both opportunities and challenges, including issues related to the family, in addition, the data highlighted difficulties related to the educational process (i.e. a lack of variety of educational methods) and technical issues related to access to the Internet and the insufficient computer skills of both teachers and students. The findings have several important implications for future practice, including the need for training workshops for parents concerning the online platform, as well as further research to determine students' perspectives of their experiences with distance learning.

This paper describes some major trends in primary and secondary education now. It is a selective views of significant topics with important implication for the future. These trends are summarized as follows, after examining historical development of Teaching-learning Methodology in primary and secondary education. 1. Education is seen as part of interdisciplinary world; emphasis is on relating education to the students' world, which is not compartmentalized. 2. Emphasizing students' individual growth with their own goal of lives. 3. Open-education with variable contents and purposes of education. 4. Education for all from that for some. 5. Consructivist based from behavior based. 6. Cooperative learning, peer tutoring, group projects. 7. Authentic assessment; assessment integrated with instruction. 8. The teacher is a facilitator of learning and a learner as well; students are learners and teachers in some situations; networks emerge instead of one-way forms or communication. 9. Spiral curriculum from single exposure.

본 연구는 과학 교과교육학 이론이 예비과학교사에게 어느 정도 필요한지에 대한 과학교육 연구자들의 의견을 알아보고자 하였다. 이를 위해서 과학교육 전공교수들의 설문을 통해 과학교사의 역량과 소양 측면에서 과학 교과교육학 이론들의 세부 내용들이 어느 정도 중요한지에 대한 의견을 분석하였다. 또한 중등과학교사신규임용후보자선정경쟁시험(중등과학교사 임용시험)에 제시된 과학 교과교육학 이론 관련 문항을 분석하여 과학교육 연구자들의 의견과의 차이점을 비교하였다. 그 결과, 과학교육 전공교수들은 탐구과정, 과학지식 평가, 탐구능력 평가 실험장치 및 도구 사용법, 실험실 안전, 학생의 오개념, 토론, 논술 등에 대해서 중요하다고 인식하고 있었다. 반면에, 과학교육 전공교수들은 과학 철학, 과학교육과정의 변천, 외국 교육과정, 브루너의 수업이론, 카플러스 순환학습모형, 발생학습모형, 발견학습모형, 클로퍼 교육목표 분류 등의 내용이 상대적으로 덜 중요하다고 인식하고 있었다. 중등과학교사임용시험 문항 분석 결과, 교육과정이나 오수벨 이론 등과 같이 중요도와 관계없이 편중된 영역에서 많은 문항들이 출제된 것으로 나타나 과학교육 연구자들이 중요하게 생각하는 이론의 중요성과 중등과학교사임용시험에서 출제된 문항 분포는 관련이 적었다. 본 연구는 과학교육 연구자들의 의견과 중등과학교사임용시험 출제 경향의 차이를 줄이는 방안 마련이 필요함을 시사한다.

과학의 본성에 대한 학생들의 이해는 과학적 소양을 길러 일상생활의 문제해결에 도움을 주기 위해 필요할 뿐 아니라 학생 개인의 과학학습에 미치는 영향에 의해서도 그 중요성을 간과할 수 없다. 이런 맥락에서 살필 때 현재 7차 교육과정에서 과학 교육을 받고 있는 학생들의 과학의 본성에 대한 관점이 어떤가를 살펴보고 이것이 기존의 연구에서 나타난 7차 교육과정 이전의 학생들의 과학의 본성에 대한 관점과 비교할 때 차이가 있는지를 살펴보는 것은 그 차이에 기여하는 요인이 무엇인지를 살펴보기위한 첫걸음이 될 수 있다. 그러므로 본 연구에서는 7차 교육과정의 인문계 고등학교에서 교육을 받은 1학년과 2학년 학생들의 과학의 본성에 대한 관점을 조사하여 관점의 분포를 알아보고 그 결과를 기존 연구에 나타난 7차 교육과정이전에 과학의 본성에 대한 1학년과 3학년 고등학생들의 관점과 비교하였다. 7차 교육과정에서 교육을 받은 고등학생들은 과학의 본성에 대한 하위차원에 있어서 전반적으로 상대주의, 연역주의 관점이 유의미하게 증가하고, 비상황주의에서 상황주의 관점으로 변화된 것으로 나타나 과학 철학적으로 일관되게 과학의 본성을 인식하고 있는 것으로 나타났다. 그리고 7차 교육과정 이전의 학생들에 비해서 유의미하지 않지만 좀 더 도구주의적인 관점을 갖고 있었다. 과학교육에서 과학지식보다는 과학적 방법과 과정을 중요하다고 보는 생각은 7차 교육과정 이전의 과학 교육을 받은 학생들과 같지만 인식의 정도에서는 유의미한 감소가 있었다. 이러한 차이의 원인으로 여러 가지를 생각할 수 있겠으나 선행연구를 통하여 교과서에서 과학사의 도입과 탐구활동의 변화가 영향을 줄 수 있음을 논의 하였다.

In recent years, deep reinforcement learning (DRL) models are enjoying great interest as their success in a variety of challenging tasks. Deep Q-Network (DQN) is a widely used deep reinforcement learning model, which trains an intelligent agent that executes optimal actions while interacting with an environment. This model is well known for its ability to surpass skilled human players across many Atari 2600 games. Although DQN has achieved excellent performance in practice, there lacks a clear understanding of why the model works. In this paper, we present a visual analytics system for understanding deep Q-network in a non-blind matter. Based on the stored data generated from the training and testing process, four coordinated views are designed to expose the internal execution mechanism of DQN from different perspectives. We report the system performance and demonstrate its effectiveness through two case studies. By using our system, users can learn the relationship between states and Q-values, the function of convolutional layers, the strategies learned by DQN and the rationality of decisions made by the agent.

In this study, we operated science teacher learning community to enhance professionality of elementary science teachers. 8 participants with various background, which include their science content knowledge, teaching experience and beliefs about teaching, were involved in this study. Bales(1950)'s social interaction process framework was mainly used to understand the members' interaction, focusing particularly on process aspects not on contents aspects. The data analysis shows that the members in the science teacher learning community tried their best to maintain the positive reaction to other members in most occasions in the community meetings. On the other hand, there were also negative reaction process due to their different ideas and views, causing their emotional conflicts in some social relations and dialogical situations. Nevertheless, the results also imply that the dual reaction processes, which are positive and negative processes, are equally important to facilitate science teachers' professional knowledge and experience. The educational meanings are discussed in the aspects of science teacher education.

The purpose of this study was to explore characteristics of sixth grade students' opistemological beliefs in science and the relationship to learner's characteristics: learning motivation, learning strategies, and logical thinking. The subjects were 265 sixth graders and data was collected through two types of questionnaires, translated and modified by researchers: opistemological beliefs regarding science, learning motivation & strategies. The results of this study were as follows. The students believed that the goals of science were related to activations such as 'Science is experiment', or 'Science is invention: These beliefs were connected with the emphasis of science classes or the focus of the science curriculum. However, the students' beliefs related to the changeability of science knowledge, the source of science knowledge, and the role of experiments in developing knowledge were oriented to modern opistemological views. Moreover, the beliefs were meaningfully related to students' characteristics: learning motivation, learning strategies, and logical thinking. Among the students' characteristics, logical thinking was especially related to all of the factors of students' beliefs: the changeability of science knowledge, the source of science knowledge, and the role of experiments in developing knowledge. However, the students who believed that scientific knowledge came from scientists, science teachers, or science textbooks had high levels of self-efficacy. Therefore, the belief that scientific knowledge is formed by self-discovery, in order to generate high self-efficacy, needs to be encouraged. From the results, it is possible to check the orientation of current science education based on the students' opistemological beliefs. In addition, the resources can be accumulated for persevering in our efforts to achieve a positive orientation for science education.

This qualitative study investigated two preservice teachers' conceptual ecologies in professional development during the science teacher preparation program. The notion of a conceptual ecology contains nature of knowledge, science and science teaching, learning, and content knowledge and comfort level. The data were collected during the participants' preservice year and their practicum experience. Both data collections and analyzing were from the various sources of interviews, teaching observations, journals, and information and profiles by the participants' supervisor. Two preservice teachers serve as cases representative of this study. Results show that problems preventing the preservice teachers from moving closer to conceptual change teaching were their understandings of the nature of science and the nature of knowledge. The preservice teachers' views about knowledge come from, and what knowledge is, are largely shaped by the nature of science and learning drive pedagogy and classroom practice. Knowledge of and comfort with the subject matter are also important.

Science education has been in a state of crisis for some time. To understand the science teacher's role, it is helpful to reconsider an aspect as fundamental as the nature of science. Since teaching cannot be separated from learning and knowledge, their very close dynamic processes need to prescribe the role of the teacher and student simultaneously. However, traditional views are limited because they tend to emphasize some particular selected aspect of learning and teaching. This paper investigates the epistemology of Michael Polanyi (1891 1976), which is often considered to transcend the confrontation between objectivity and subjectivity of knowledge. Polanyi reconceptualized science knowledge as 'personal knowledge' based on his own experience as a scientist and a thinker. In this study, I discuss 1) the nature of science in light of Polanyi's epistemology, 2) what this says about the meaning of science learning and teaching, 3) the potential of these ideas for the role of the science teacher.
