  • The purpose of this study is to develop scientist vignettes and to explore their effects to change students' perceptions of scientists, scientific attitudes, and the nature of science. The scientist vignettes developed in this study include research cases on seven scientists, including British zoologist Jane Goodall. Each vignette consists of 4 to 6 pages in consideration of the reading level of elementary school students, and contains illustrations describing the main contents of the text. In addition, scientist vignettes contain descriptions on terms and text boxes explaining the higher concepts, and each vignette contains questions that students can think deeply based on the story of the scientist. To verify the educational effectiveness of scientist vignettes, we investigated changes in their perceptions of scientists, scientific attitudes, and the nature of science in 564 elementary school students. We conducted group interviews with four elementary school teachers. As a result of conducting pre-test and post-test using a narrative questionnaire consisting of 6 questions, students became more sophisticated in the understanding of the science and the characteristics of scientists after experiencing scientist vignettes and their understanding the nature of science changed into a more modern epistemological perspective. Also, in a group interview with teachers, teachers assessed that scientist vignettes would positively affect the understanding of science process skills and the nature of science, and forming a scientific attitude, especially in increasing understanding of the nature of science. We discussed ways to effectively utilize scientist vignettes in elementary school science education based on these result.

  • This study was designed to 10 questions as development of GAP program for ninety high school students(each student of 30 with achievement as high, medium, and low categories), it was analyzed the perception of Earth scientist. High school students have a positive perception about a course in Earth science, but they have lack of knowledge about Earth scientist as a career man, and they can't recognize Earth scientist as a career. A failure of learning of Earth science for Students with low level achievement leads to a negative perception about Earth scientist and disconnection to future career. School education should provide an opportunity to encounter Earth scientist for students and it is badly in need of effort to connect to the job training program.

  • A number of studies have shown that students have a stereotyped image of a scientist, and this image is often a rather negative. Earlier work on images of the scientist revealed to be consistent across the various social classes and across countries. This study aimed to examine a Korean students' stereotyped images of scientist, compare it with earlier work, and also find out whether students have other ideas about scientist, apart from the stereotyped image. To these purposes, modified DAST and individual interviews were carried out with 217 students and 53 students, respectively. The results are as follows : 1. Most of the students portrayed the scientist as a neat and young man with well-featured face, which was different from earlier studies. 2. Year 3 boys described the scientist as a mu, but year 3 girls as a woman. 3. Most of the students gave positive answers which were at variance with the streotyped image. 4. An interview asking only one question was a complement to DAST. It was concluded that students have private perceptions of scientists and their work, as well as a stereotyped image.

  • This article aims to (a) investigate children's images of a scientist's life style by comparing children's drawings about a scientist's schedule with those about a company employee's schedule in a weekday and on Sunday; and (b) examine the usefulness of 'Drawing A Scientist's Schedule (DASS)' test as a new instrument of learners' conceptions of a scientist and his/her work. To do those, thirty sixth- grade children participated in this study. The children, 15 boys and 15 girls, were selected from a classroom of an elementary school located in Gongju city. The children's drawings were analyzed in conjunction with individual interviews. The interviews facilitated the clarification of any ambiguous attributes of the drawings by questioning after their completion. Several significant conclusions can be drawn from this work: First, the children conceived that a scientist has more mandatory time, and less necessary and leisure time than does a company employee. Interestingly, many children thought that a scientist has similar life style on Sunday to that in a weekday, unlike a company employee. Second, in case of necessary time use in a weekday and on Sunday, the difference between a scientist and a company employee results from their sleeping time. Also, the children showed more various conceptions of a scientist's sleeping time than those of a company employee's sleeping time. Third, in case of mandatory time use, the children conceived that a scientist spends more time for his/her occupational work and less time for his/her housework activities than does a company employee. Fourth, the children's drawings showed that there is difference between a scientist's and a company employee's leisure time use and activities. Finally, the DASS test indicated its possibility and usefulness as an instrument for investigating learners' images on a scientist and his/her work. The instrument exhibited several distinctive children's conceptions that is difficult in identifying by using the DAST, a popular instrument.

  • As the global business environment is rapidly changing due to the 4th industrial revolution, new jobs that did not exist before are emerging. Among them, the job that companies are most interested in is 'Data Scientist'. As information and communication technologies take up most of our lives, data on not only online activities but also offline activities are stored in computers every hour to generate big data. Companies put a lot of effort into discovering new opportunities from such big data. The new job that emerged along with the efforts of these companies is data scientist. The demand for data scientist, a promising job that leads the big data era, is constantly increasing, but its supply is not still enough. Although data analysis technologies and tools that anyone can easily use are introduced, companies still have great difficulty in finding proper experts. One of the main reasons that makes the data scientist's shortage problem serious is the lack of understanding of the data scientist's job. Therefore, in this study, we explore the job competencies of a data scientist by qualitatively analyzing the actual job posting information of the company. This study finds that data scientists need not only the technical and system skills required of software engineers and system analysts in the past, but also business-related and interpersonal skills required of business consultants and project managers. The results of this study are expected to provide basic guidelines to people who are interested in the data scientist profession and to companies that want to hire data scientists.

  • The main purpose of this study is to investigate the Korean youths' impressions of the scientist. The concept of impression is assumed to reflect our significant view of an object better than that of image. That is, the basic assumption is that we tend to behave toward an object, based on its impression which is conceived to be "significant". In late August and early September 2002, a national survey for 1,204 youth (406 for 5th grad; 381 for 8th grade; and 417 for 11th grade) was conducted to find the Korean youths' impressions of the scientist. Our major finding is that the Korean youths' most impressions of the scientist were re his or her activities such as inventing, experimenting, researching, etc. And the major sources of those impressions were found to be television, book, and class. Other findings were about youths' impressions of the science teacher and opinions of the scientist as a profession. Finally, some policy-related implications based on survey results were presented at the end.

  • This study examined young Korean children's perceptions about scientists, kindergarten science and the application of science in their daily lives. An interview questionnaire developed by the researchers and based on Chamber (1983)'s Draw-A-Scientist Test (DAST), was administered to 104 five-year-old children. Most of the children (68.2%) saw themselves doing activity-oriented science in kindergarten, but they did not use outside kindergarten for the knowledge and skills they learn in science (70.4%). In general, children recognized scientist as a male working with lab equipment in the laboratory. Although most of children (74.5%) were interested in science, only a few of them (12.5%) hoped to be a scientist in the future. There were significant differences attributable to gender in preference for science; girls showed more interest in science than boys.

  • The purpose of this study was to analyse middle school students' images and perceptions about scientist, technician and engineer and to compare the images of male students with those of female students. Fralick et al.(2009)'s "Draw a scientist at work and draw an engineer at work" was modified and administered to 110 middle school 3rd grade students (43 male students, 67 female students) from 5 middle schools. They drew the figures at work and took explanation of what the person was doing in a drawing. The results of this study were as follows; First, the representative image of scientist was the man with glasses and lab gown performing the chemical experiment. There were no significant differences between the male students and female students in terms of the scientist images. Second, the representative image of technician was the man who was fixing a car and working with his hands. The technicians were illustrated as working with tools such as wrench, hammer and so on. There were no significant differences between the male students and female students in terms of the technician images. Third, the students involved in this study frequently perceived male engineers as working indoors. But perceptions about performance of engineers were significantly different between male students and female students. A majority of male students recognized that engineers should design, invent and create the products, however many female students perceived the engineers as car mechanics. Fourth, the students perceived differently the scientists' task compared with the technicians', but they had difficulty in distinguishing the scientists' task from the engineers' task.
