  • An analysis was done on the “inquiry sections” of Earth Science chapters of 10th grade science textbooks. The Inquiry sections were classified into different types and the frequencies of basic process skills, integrated process skills, and inquiry activities were measured in section to find out whether they sufficiently satisfy the requirements based on the 7th National Curriculum. The number of selected science textbooks that have been used in high school for this study were eleven. The number of inquiry tasks were on an average of 24.0. The types of inquiry sections and the elements of basic and integrated process skills were different in every textbooks. The number of inquiry activities were also different and analyzed more than those presented. They were not integrated activities but presented as scientific process skills. The basic process skills and integrated process skills presented in textbooks were $16\%\;and\;77.2\%$, respectively. However, the distribution of two kinds of process skills were analyzed to be $45.6\%\;and\;55.4\%$, respectively. In the process skills, the frequencies of inferring $(49.5\%)$ and data interpretation (68.7%) were the highest; however, the other process skills including recognizing problem, formulating hypothesis and generalization were not even presented in any of the text books. Due to the lack of the definitions of Science process skills and inquiry activities in the 7th National Curriculum, each text book defined these terms differently. It suggests that the meaning of inquiry, science process skills, and inquiry activities should be operationally defined in the national curriculum and the criteria for construction of inquiry activities are required.

  • Line graphs are frequently used to communicate data and basic concepts in classroom activities, Science teachers often assume that students are able to interpret the symbolic meaning of the graphs, but such an assumption is not based on sufficient evidence, The purpose of this study was to investigate the relationships of graphing ability to science-process skills and academic achievement of high school students: With regard to science-process skills, graphing ability was found to have a slight correlation with science-process skills (.41). Among the sub-skills of the science-process, graphing ability was seen to have a relatively high correlation with basic science-process skills such as 'measuring', 'inferring', 'predicting', while having relatively low correlation with integrated science-process skills such as 'formulating hypothesis' and 'generalization', With regard to academic achievement, graphing ability appeared to have no correlation with academic achievement (.06). Hence, a correlation between graphing ability and science-process skills was proved. It can also be concluded that improving graphing ability will greatly support students with their science study and, therefore, organized efforts and efficient educational methods should be developed in order to overcome the insufficient graphing ability among high school students.

  • The purpose of this study is to examine the effects of small group inquiry skills on improving science process skills and attitudes toward science in elementary school science. The research questions of this study were as follows. First, effects of small group inquiry skills on improving science process skills in elementary school science. Second, effects of small group inquiry skills on improving attitudes toward science in elementary school science. The subjects of this study is two classes from 6th grade elementary classes in Busan. The experiment class practiced small group inquiry skills, while the control class practiced self inquiry. To verify the effect of the experiment, ANOVA was conducted. The main findings of this study are as follows. First, the small group inquiry skills gave a significant influence on increasing the science process skills, including the basic science process skills and the integrated science process skills, of students. Especially, among subordinate factors of science process skills between groups, it was effective to increase abilities of observing, reasoning, interpreting data, formulating hypothesis. It is necessary for teachers to make an effort to teach according to steps of the small group inquiry skills and to support inquiry activities, in order to increasing the science process skills. However, frequency of additional lessons have a little influence on increasing the science process skills. Second, there is meaningful change in the attitudes toward science for those who studied the small group inquiry skills. Also, they affected subordinate factors of the attitudes toward science, like the attitudes toward science inquiry, the happiness about science class. This study shows that the small group inquiry skills give a positive influence on the science process skills and attitudes toward science in elementary school science.

  • The purpose of this study is to investigate how free inquiry activities affects the scientific process skills and scientific attitudes of 5th and 6th of elementary school students. For this study, 265 elementary students from 5th and 6th grade in Seoul were selected. In comparison group 130 students were implemented and to the experimental group 135 students who did not the free inquiry activities were implemented. The result of this study is as follows: First, curiosity was the most affective factor that motivate free inquiry activities and made them select their topics. Most of the students invested for the inquiry activity in less than 3 weeks. They had some help in every stages. Students became interested in free inquiry activities because they learned new facts and enjoyed doing experiments and they wanted to continue for the same reasons. Second, free inquiry activities had little effect on the basic science process skills of the experimental group, compared to the control group at the significant difference of p=0.05. Third, free inquiry activities had considerable effect on the integrative inquiry process skills of the experimental group, compared to the control group at the significant difference of p=0.05. Fourth, the result of the post-test of the experimental group showed that free inquiry activities had no effect on scientific attitudes at the significant difference of p=0.05. In conclusion, free inquiry activities will be much more effective in developing integrative inquiry process skills than in developing basic scientific process skills and scientific attitudes.

  • This study was to examine elementary male and female students' spatial abilities, science process skills, and graph construction and interpretation abilities in order to understand the effect that their spatial abilities and science process skills would have on their graph abilities. To conduct this study, total 12 classes of 435 pupils, 6 classes each from grades 5 and 6 in elementary schools were selected for subjects. The number of male student was 207 and that of female one was 228 of them. And previous test papers of spatial abilities, of science process abilities, and of graph abilities were retouched and updated for reuse in new tests. The results of this study are briefed as follows: Firstly, when spatial abilities for male and female group were compared, female group showed a little higher rate of correct answering than male, but not providing statistically significant gap. Secondly, the science process skill tests revealed basic process skills of both groups were more excellent than their integrated process skills, while female group was found to have more correct answers than male, all of which were proving statistical distinction. Thirdly, of graphing skills for two groups, the graph interpretation skills turned out to be better than the graph construction skills, with female group scoring higher than male and with meaningful difference. Fourthly, both between spatial abilities and graph abilities, and between science process skills and graph abilities, static correlations existed with statistical meaning. In other words, those with higher spatial abilities or science process skills were to do better in constructing and interpreting graphs.

  • This paper examines the effects on academic achievement, scientific process skills and affective domain for elementary students learning the 'Chicken life cycle' through traditional science class versus a smart media based STEAM approach. Students designed and built a hatching jar and created a smart media content for chickens using time-lapse technology. This STEAM program was developed to improve their scientific concepts of animals over nine periods of classes using integrated education methods. The experimental study took place in the third grade of public schools in a province, with the STEAM approach applied in 2 classes (44 students) and the traditional discipline approach implemented in 2 classes (46 students). The STEAM education significantly influenced the improvement of academic achievements, basic scientific process skills and affective domain. The results suggest that this STEAM approach for teaching scientific concepts of animal life cycles has the performance in terms of knowledge, skills and affect gain achievements in elementary school students' learning when compared to a traditional approach. Moreover, the smart media based STEAM program is helpful to lead students to engage in integrated problem-solving designs and learning science and technology.

  • Inquiry activity is a major source of student investigation which both of the national curriculum standards strongly emphasize for achieving scientific literacy. The purpose of this study was to examine inquiry activities incorporated in high school biology textbooks used in China and Korea. The inquiry activities were examined with regard to inquiry level and science process skills. Bell's and a modification of Padilla's framework were used in these analyses. Results show that the Korean textbooks were more exclusively occupied by simple inquiry activities - None of them provided activity more complex than level 2 inquiry. In addition, the Korean textbooks had uniformly basic science process skills, whereas their Chinese counterparts gave students some challenges for higher level process skills. Therefore, it cannot be guaranteed that the activities in the Korean textbooks are helpful in guiding students toward a gradual progression to high-level inquiry. Implications for inquiry-based science education were suggested based on the results of the study.

  • The purpose of this study was to develop a plan to ensure that students lacking basic science skills acquire the minimum needed science learning ability while completing the common curriculum. We surveyed 27 elementary and secondary science teachers with experience in research and teaching related to basic skills support to investigate their perceptions of the criteria for minimum achievement standards using Consensual Qualitative Research (CQR) and Analytic Hierarchy Process (AHP). The results indicated that the science teachers tended to describe low achievers as lacking science learning competency, accumulating a science learning deficit, and lacking prerequisite knowledge. However, there were some differences in the characteristics that the elementary and secondary teachers paid attention to in students with insufficient science and basic academic skills. Specifically, the secondary teachers demonstrated greater sensitivity towards low learning motivation and difficulties in using scientific symbols, whereas the elementary teachers were more sensitive towards students' attitudes towards science or lack of experience. Furthermore, it has been observed that the prioritization of items, categorized by school level, differs in terms of setting minimum achievement standards to ensure basic skill support. This implies the need to develop minimum achievement standards considering various variables based on the school level. As there are diverse opinions among science teachers, depending on their expertise, regarding the factors to be considered when developing these standards to guarantee science and basic skill support. Based on the findings of the study, policy support is required to enhance teachers' professionalism in developing students' basic skills while considering the individual context and diversity of low achievers. Additionally, it is crucial to establish a shared vision for students lacking basic skills to reduce the gap between national policy and the practices of science teachers in ensuring support for basic skills.
