  • The research focuses on the provincial universities in the western region of China and investigates the research level of 12 provincial universities from 2017 to 2021, considering both static efficiency and dynamic efficiency. The static efficiency is examined using Data Envelopment Analysis (DEA), while the dynamic efficiency is analyzed using the Malmquist model. The analysis results are as follows: the scientific research efficiency of universities in the 12 western provinces is generally not high. Against the background of the "Double First-Class" construction, the overall efficiency of scientific research in universities is showing an increasing trend. The main reason for the increase in scientific research efficiency is the increase in scale efficiency in recent years. The total factor productivity (TFP) of research activities is influenced by the technology progress index and exhibits a pattern of initial increase, followed by a decline, and then an increase again. Research conclusion: Western colleges and universities should reasonably allocate resources for scientific research activities, perfect scientific research mechanisms, improve management standards, promote scientific innovation and corresponding achievements, and ultimately raise the scientific and technological level in western China.

  • The purpose of this study was to develop forensic science program for the improvement of scientific creative problem-solving abilities in gifted elementary-school students. A program that consists of six sessions (18 hours) is developed in accordance with the CPS model, which has been already proven effective for the improvement of creative problem-solving abilities. This program was applied to sixth-grade 18 gifted students in an elementary school in Gyeonggi province. Examinations of scientific creative problem-solving abilities were performed before and after applying the program in order to determine its effect on gifted elementary students. A qualitative analysis of students' activity sheets, peer assessment and teacher's class journal was made in order to examine the process of improvement of students' scientific creative problem-solving abilities. The results of this study are as follows: First, forensic science program to enhance the scientific creative problem-solving abilities of gifted students was developed. Second, forensic science program is significantly effective in the improvement of scientific creative problem-solving abilities of gifted children of elementary school (p<.05). Third, in early stage of the class, a student, who showed the highest range of change in pre and post tests, revealed the trend of responding in a short answer type. In the late stage of the class, he revealed the capability of producing various creative ideas promptly. On the other hand, students belonging to the upper group of both pre and post test revealed the improvement of divergent thinking skills such as fluency, flexibility, and originality. Fourth, after class, the students responded that the forensic science program developed in this study intrigued the interests and curiosities, and helped them break away from fixed ideas.

  • The purpose of this study was to investigate the effect of small group discussion and debate emphasizing maker class on elementary school students's science learning motivation and scientific attitude. The conclusion of the study is as follows. First, it was shown that the small group discussion and debate emphasizing maker class had a statistically significant effect on elementary school students's science learning motivation. This is due to the fact that the small group discussion and debate emphasizing maker class stimulates students' interaction, which is why students are more interested in class while solving problems with their peers. Second, it was found that the small group discussion and debate emphasizing maker class had a statistically significant effect on the elementary school students' scientific attitude. This allows students to have enough opportunity to express their opinions through small group discussions and debate, and I think that because they listen to others' opinions when they make new things or make new plans, so they have been able to increase their scientific attitude continuously. Third, based on the analysis of the participant students' opinions on the small group discussion and debate emphasizing maker class, all the participants answered that they were interested in this kind of class and they want to participate in this kind of maker class again. Therefore, it is thought that the small group discussion and debate emphasizing maker class can play a big role in raising the elementary school students's science learning motivation and scientific attitude.

  • The use of evidence is very important in scientific argumentation. This study investigated the types and levels of evidence in scientific argumentation in an elementary science class. 34 fourth graders in a class were selected as subjects, and argumentation was performed in seven lessons on 'Heat transfer and our lives' unit. Small group argumentation was recorded, transcribed and used as data for analyses. The analyses found the following results. First, in regard of the types of evidence, personal evidence dominated over authority-based evidence. Second, in the analysis of the levels of evidence, using inappropriate evidence was found to account for the highest percentage, followed by using appropriate evidence and just arguments without evidence. There were quite a lot of cases of arguments without evidence. It was found that the types and levels of evidence that students used could change depending on the relevance between experiments and argument tasks.

  • The main purpose of this research is to search the effect of different types of advance organizers in elementary science classes, to the students in acquiring scientific concepts and its retentions. In order to proceed with the research, We have chosen 93 students of three different classes of fifth graders, studying in M elementary school in U metropolitan city. We have randomly chosen two classes as an experimental group and one class as a comparative group. In the first experimental group (Group1), advance organizer was put in a form of a sentence., and the second experimental group (Group2), advance organizer was put in a form of a picture. For the comparative group, We have not put any advance organizer, and the method of class was proceeded as it was before. The result of this research are as follows. Firstly, the result of 'One-way analysis of variance' on scientific concept grade, right after the experiment on three groups, has shown a meaningful difference that, the shape of advance organizer does affect the acquisition of elementary school students' scientific concept. Secondly, even though Group1, who was given with a sentence as an advance organizer, got higher scientific concept scores after the experiment than that of comparative group, However, there was not a meaningful difference between Group1 and comparative group. Thirdly, Group2, who was given with a picture as an advance organizer, has shown a meaningful difference from comparative group. Judging from the facts above, utilizing an advance organizer of a picture in elementary science class, will be very affective on students' acquiring scientific concept.
