Focusing on the role of the science museum as an institution to improve the scientific literacy of the public, this study investigated public perception and behavior about science museum to know how much science museums affect the public by using social media big data analysis. For this purpose, we extracted texts containing 'science museum' in Naver blogs and Twitter, analyzed them by using network, frequency, co-ocurrence, and semantics analysis and compared them with the results in English speaking countries. As a result, blogs were mainly concerned with science museum among parents who have young children, while in Twitter posts from many students who visited as a group appeared. Therefore, the Korean public used science museum mainly as a space for children's experience, and in this case, programs and exhibitions of science museums are perceived positively. On the other hand, students who visited as a group showed some negative emotions. The result of comparison with the cases of foreign countries in terms of the function of the third generation science museum such as communications with the science museum and the public and the participation of the public in science, the Korean public hardly mentioned the scientific contents, words related to communications such as 'argue', and curators or staff after visiting the science museum. In contrast to many verbs related to meaningful activities such as 'learn', 'participate', 'listen', 'read', 'ask', 'think' appeared in English, only a small number of verbs include 'ask' and 'thin' appeared in Korean. Therefore, science museum need to improve impression, communicating with public, and involving activity with impact and variety after visit.

The nature of science has been recognized in a great deal in the field of science education. However, only few innovative programs are offered for science-gifted students to improve their recognition of the nature of science. The current study describes and analyzes science-gifted students' understandings of the nature of science (NOS). In addition, the study looks into contradictory views among the aspects of NOS, which are fundamental data in constructing target programs on NOS for science gifted students. Data used in this study were collected from 73 middle school science-gifted students using an open-ended questionnaire, VNOS. The results of this study showed that the participants' understanding of NOS was significantly distributed on naive or transition view except for 'tentative NOS', and the results revealed inconsistent view among the aspects of NOS. This study proposes two suggestions to enhance the recognition of science-gifted on NOS of science to informed state and to have consistent perspectives with other areas. First, the role of experiment has to be changed-it should be the process in constructing scientific knowledge rather than an instrument to check scientific knowledge to transform perspective on experimental data and scientific knowledge. Second, various opportunities must be provided to science-gifted students, so they can experience the culture and community of scientists and science to gain a wider insight of science.

Heuristic is a empirical method that is used quickly when uncertainty or insufficient time and information are insufficient. The purpose of this study is to find out what heuristics appear in the processing of the experimental manual among science experiment activities of elementary school students. To do this, 20 fifth-grade elementary school students (female 10 and male 10) were required to conduct scientific experimental activities as research participants to collect experimental behavior data and gaze movement data, and retrospective interviews were conducted. The collected data extracted and conceptualized behavior by heuristics. As a result of the study, there were five heuristics that appeared in the processing of the experimental manual: "reducing the difference between the target state and the current state," "guessing the experimental procedure," "paying attention to the expected results," "comparing with the picture of the experimental manual," and "using a trial and error strategy." According to each concept of heuristics, there were favorable and unfavorable aspects for experimental activities. In science experiment activities that students experience for the first time, there is a lack of information and the situation is uncertain, so behavior by heuristics appears in nature. Therefore, educators need to understand students' heuristics and guide scientific experimental activities.

Materials and techniques used for two portraits (Jo-nyeon Lee and S ung-in Lee) of the Lee family from Seongju enshrined in Seongsan temple were scientifically analyzed, and based on the data, an optimal replica restoration method was designed. According to the expression technique investigation, both portraits were expressed mainly in line drawing, but there were differences in shoes, pupils, the color expression of flesh, overpainting, and traces of reinforcement. Pigment analysis revealed that a mixture of cinnabar and minium, organic pigment, azurite, malachite, lead white, and yellow pigment were used in common. In the case of Sung-in Lee's portrait, seokganju and atacamite were also used. In addition, comparison with the contemporaneous portraits of gentry showed that the portrait style at the time was found in the two portraits, but the singularity was modified differently there. Based on the scientific analysis, it was decided to replicate the old color restoration for Jo-nyeon Lee's portrait while for Sung-in Lee's portrait, it was decided to replicate the phenomenon. Detailed coloring techniques were presented by supplementing the expression techniques that are difficult to confirm visually using scientific data. In addition, by measuring the chromaticity of representative positions in the portrait for each color and presenting the color reference value calculated as the average value, the current color of the artifact can be replicated and restored based on the objective data as much as possible.

With the advancement of the Internet/IT technologies and the increased computation power, massive data can be collected, stored, and processed these days. The availability of large databases has brought forth a new era in which companies are hard pressed to find innovative ways to utilize immense amounts of data at their disposal. Indeed, data has opened a new age of business operations and management. There are already many cases of innovative businesses reaping success thanks to scientific decisions based on data analysis and mathematical algorithms. Big Data is a new paradigm in itself. In this article, Big Data is viewed as a new perspective rather than a new technology. This value centric definition of Big Data provides a new insight and opportunities. Moreover, the Business Analytics, which is the framework of creating tangible results in management, is introduced. Then the Internet of Things (IoT), another innovative concept of data collection and networking, is presented and how this new concept can be interpreted with Big Data in terms of the value centric perspective. The challenges and opportunities with these new concepts are also discussed.

This paper aims to find out whether or not elementary school students recognize and understand scientific units that they encounter in their everyday life. To select appropriate units for the survey, first, scientific units in elementary textbooks of science and other science related subjects were analyzed. Then it was examined how these units were related to the learners' daily life. The participants in the current survey were 320 elementary school 6th graders. A questionnaire consisted of 11 units of science, such as kg for mass, km for distance, L for volume, V for voltage, s for time, $^{\circ}C$ for temperature, km/h for speed, kcal for heat, % for percentage, W for electric power, pH for acidity, which can often be seen and used in daily life. The students were asked to do the following four tasks, (1) to see presented pictures and select appropriate scientific units, (2) to write reasons for choosing the units, (3) to answer what the units are used for, and (4) to check where to find the units. The data were analyzed in terms of the percentage of the students who seemed to well recognize and understand the units, using SPSS 17.0 statistical program. The results are as follows: Regarding the general use of the units, it was revealed that almost the same units were repeated in science and other subject textbooks from the same grade. With an increase of the students' grade more difficult units were used. As for the use of each unit, it was found that they seemed to relatively well understand what these units kg, km, L, $^{\circ}C$, kcal, km/h, and W stand for, showing more than 91% right. However, the units of V, s, in particular, %, and pH did not seem to be understood. With respect to the recognition of the units, most students did not recognize such units as L for volume and pH for acidity, probably because the units are difficult at the elementary level in comparison to other scientific units. The students indicated that schools were the best place where they could learn and find scientific units related to life, followed by shops/marts, newspapers/broadcasting, streets/roads, homes, and others in that order. The results show that scientific unit learning should be conducted in a systematic way at school and that teachers can play a major role in improving students' understanding and use of the units.

In this study, we explored the development of scientific model through the social-construction process on "combustion." Students were 8th graders from one middle school class. Each student engaged in small group discussions three times and made a group model on combustion. Discourses between peers and teacher were videotaped, audiotaped, and transcribed. The results show that the small groups constructed an initial concept: 'Conditions of combustion', which they then evaluated and revised the initial concept through combustion experiment. Following the discussions, some small groups evaluated their model and made a revised model. Then, the small groups compared various models and constructed a scientific model through consensus within the small group and as a whole class. Finally, students kept revising their model to 'Burning needs oxygen.' This tells us that the social construction process of scientific model made a meaningful role to build scientific model through diverse discussion between the students and their teacher, although they have had some difficult process to reach the final consensus. The data also showed some group features: the members were open to other's ideas. They analyzed the differences between their own ideas from others and revised their model after the whole class discussion. Lastly, they showed the tendency to make a good use of teacher's guidance. This study implies the importance of having social interaction process for students to understand the scientific model and learn the nature of scientific inquiry in class.

The purpose of this study is to investigate elementary teachers' views on the democratic scientific inquiry and the methods for promotion of democratic citizenship in science classroom, and to conduct exploratory discussions about science classroom for promotion of democratic citizenship based on their views. Data were collected from 96 elementary teachers. AS results show, the elementary teachers in the study thought that the features of democratic scientific inquiry was 'communication and cooperation', 'autonomy and fairness', and 'contribution to the benefit of mankind and society'. In addition, the participants regarded the 'inquiry/activity focused on communication and cooperation' as the best method for promotion of democratic citizenship in science classrooms. Finally, several suggestions on the science education for promotion of democratic civic literacy and the democratic inquiry were given.
