본 연구의 목적은 중등과학교사신규임용후보자선정경쟁시험(이하 중등과학교사임용시험)의 문항들에서 어떤 과학교육학 이론이 제시되었는지를 분석하는 것이다. 이를 위해 최근 5년간 시행된 중등과학교사임용시험의 과학교육학 관련 문항들을 과학과 교육과정, 과학사 및 과학철학, 과학 탐구, 과학 교수학습이론, 과학 교수학습모형, 과학 평가 등의 6가지 영역으로 분석하였다. 그 결과, 과학 교수학습이론이 다른 영역에 비해 가장 많이 출제되었고, 각 영역 내에서는 '차시별 교육과정의 내용요소', '과학적 방법'과 '현대과학철학', '탐구과정요소', '오수벨의 유의미학습', '로슨의 순환학습'과 '협동학습', '수행평가 준거 개발' 등에서 많은 내용이 출제되었다. 반면에, 과학교육자들 사이에서 '과학사'와 같이 예비 과학교사에게 중요한 주제로 여겨지지만 중등과학교사임용시험에서는 출제가 거의 이루어지지 않은 영역도 많이 있었다. 중등과학교사임용시험이 예비교사들의 전문성 함양을 위한 노력에 영향을 미치기 때문에 예비교사들이 익혀야 할 과학교육학 이론의 양과 수준에 대해 많은 연구가 요구된다.

The Islamic jurisprudential legal system represents an essential component of the Islamic religion, that governs many aspects of Muslims' daily lives. This creates many questions that require interpretations by qualified specialists, or Muftis according to the main sources of legislation in Islam. The Islamic jurisprudence is usually classified into branches, according to which the questions can be categorized and classified. Such categorization has many applications in automated question-answering systems, and in manual systems in routing the questions to a specialized Mufti to answer specific topics. In this work we tackle the problem of automatic categorisation of Islamic jurisprudential legal questions using deep learning techniques. In this paper, we build a hierarchical deep learning model that first extracts the question text features at two levels: word and sentence representation, followed by a text classifier that acts upon the question representation. To evaluate our model, we build and release the largest publicly available dataset of Islamic questions and answers, along with their topics, for 52 topic categories. We evaluate different state-of-the art deep learning models, both for word and sentence embeddings, comparing recurrent and transformer-based techniques, and performing extensive ablation studies to show the effect of each model choice. Our hierarchical model is based on pre-trained models, taking advantage of the recent advancement of transfer learning techniques, focused on Arabic language.

Rhetorical relations between two text fragments are essential information and support natural language processing applications such as Question - Answering (QA) system and automatic text summarization to produce an effective outcome. Question - Answering (QA) system facilitates users to retrieve a meaningful response. There is a demand for rhetorical relation based datasets to develop such a system to interpret and respond to user requests. There are a limited number of datasets for developing an Arabic QA system. Thus, there is a lack of an effective QA system in the Arabic language. Recent research works reveal that unsupervised learning can support the QA system to reply to users queries. In this study, researchers intend to develop a rhetorical relation based dataset for implementing unsupervised learning applications. A web crawler is developed to crawl Arabic content from the web. A discourse-annotated corpus is generated using the rhetorical structural theory. A Naïve Bayes based QA system is developed to evaluate the performance of datasets. The outcome shows that the performance of the QA system is improved with proposed dataset and able to answer user queries with an appropriate response. In addition, the results on fine-grained and coarse-grained relations reveal that the dataset is highly reliable.

In order to foster 'creative convergence talents' teachers and pre-service teachers who possess a certain degree of creativity must learn about this new approach as part of their teacher training. In this study, we attempted to identify the implications on the curriculum of the teacher education-training college in question by analysing secondary school teachers' and pre-service teachers' creativity and by collecting sufficient data to develop a positive feedback model for selecting, cultivating, and appointing pre-service teachers who fulfil the requirements of said college of education. Such teachers will display the commitment and professionalism to fulfil their teaching duties in the best possible manner and will consistently produce valuable contributions to their chosen subject matter and integrate these into their daily teaching. These teachers will complete all their tasks in a creative way, including student guidance, administrative duties, and academic lessons. The factors that distinguished creative teachers from others included originality and fluency. Our test group comprised 216 pre-service teachers as well as 137 fully qualified teachers. Teachers' understanding of the factors required in order to qualify as a 'creative and committed teacher' was very low. We provided data to the college of education to increase creativity when selecting teachers and curricula based on an analysis of perceptions of creativity provided by teachers and pre-service teachers.

The study aims to figure out pre-service elementary teachers' knowledge understanding on 'stratum and rock' as well as teaching-learning types on the same topic. A total of 65 seniors in an advanced science education course at B University of Education joined the research to fulfill the purpose above. With PCK classification framework, the study examined pre-service teachers' knowledge understanding on 'stratum and rock' while it analyzed how the teachers would teach the given topic to students. The results of the study are presented as follows. First, it was observed that the pre-service elementary teachers have a great understanding on 'stratum and rock' that would be taught via a science textbook for elementary fourth graders. However, regarding terms in 'shale and limestone', they appeared to have a relatively short understanding. Second, PCK elements of the pre-service teachers related to 'stratum and rock' were analyzed and according to the results, the teachers would be interested in teaching model selecting in the teaching-learning strategy field while they would be well aware of how important it is for them to perform an experiment in a teaching process. The teachers also appeared to understand that the teacher question can be mutual complementary during class. However, it turned out that the teachers would have a very much low understanding on learners' prior knowledge as they particularly believe that learning could be significantly affected by the learners' perception level as well as their learning interest and motive. Third, the pre-service elementary teachers were told to design teaching plans on 'stratum and rock' so that the study could find out what learning-teaching methods the teachers would adopt to teach the topic. It was learned that the teachers would proceed with the class basically by giving the learners a descriptive explanation on the topic and also by using pictures and drawings to enhance the learners' understanding during the class.

Voyager IRIS (Infrared Interferometer Spectrometer) observations of Jupiter's Great Red Spot (GRS) have been examined in order to extract the vertical distribution of phosphine. To the accuracy than can be achieved from this approach, there appears to be no difference between the PH3 distribution over the GRS compared with the distribution over the neighboring South Tropical Zone. This result is at variance with a pre-Voyager prediction of an enhancement of PH3 over the GRS resulting in the preferential production of red phosphorous in this location on the planet (Prinn & Lewis 1975). The composition of the red material remains an open question.

This study aimed to analyze the characteristics of good science teachings regarded by preservice elementary school teachers. It also aimed to suggest a direction of peer teaching practice to help preservice teachers' professional development. Adjacency pairs were adopted to analyze the characteristics of good science teachings. The results showed that pre-service elementary teachers were accustomed to adjacency pairs. Almost of their discourse were organized by adjacency pairs. 'Question-Answer' and 'Request-Accept' were mainly used in science classes by pre-service elementary teachers. Based on the findings, the study suggested science teacher educators to provide chances to analyze exemplary science teachers' science class or chances to analyze their science teachings in terms of competence of science classroom discourse.
