Computer programming has educational effect on improving high-level thinking abilities. However, students initially have to spend too much effort in learning the basic grammar and the usage model of programming languages, which negatively affects their eagerness in learning. To remedy this problem, we propose to apply the Scratch to a Game Developing Programming Class; Scratch is an easy-to-learn and intuitive Educational Programming Language (EPL) that helps improving the Meta-cognition and Self-efficacy of middle school students. Also we used the Demonstration-Practice instruction model with self-questioning method for activating the Meta-cognition. In summary, a game developing programming class using Scratch was shown to significantly improve the Meta-cognition of middle school students. However it was shown to insignificantly improve the Self-efficacy of girl students group.

The study aimed to investigate elementary school gifted students' hypothesis-generating ability and characteristics of hypotheses and to analyze the correlation between hypothesis-generating ability and meta-cognition. Nineteen students enrolled in a science gifted education center affiliated with a university in 2013 were selected as research subjects. An instrument of open ended items about hypothesis generating was developed and administered to students, and their meta-cognition as well as their preferred science teaching method were examined. Hypotheses generated by students were classified into two categories: scientific and non-scientific hypotheses, and then a closer analysis was conducted on characteristics of non-scientific hypotheses. It was found that 47% (18 out of 38 hypotheses) was scientific ones showing that elementary school gifted students in science in this study presented low level of ability in generating hypothesis. It was also found that non-scientific hypotheses frequently showed characteristics of uncertain in causality or impossible to verify relationships. Furthermore, differences in hypothesis-generating ability and characteristics of hypotheses were appeared in conditions whether inquiry questions and variable identification process were given or not. Students showed high abilities in hypothesis generating and variable identifying when inquiry questions and variable identification process were given. Compared to previous research results, students in the study showed high level of meta-cognition and tendency of utilizing monitoring strategy more than planning and regulating. In ill-structured conditions that students themselves find inquiry questions and identify variables, a significant (p<.05) correlation appeared between hypothesis generating ability and meta-cognition and a high level of correlation between planning and regulating strategies. It was also found that differences existed in hypothesis-generating ability and preferred science teaching methods between students with high level and those with low level of meta-cognition; and students with low level of meta cognition showed difficulties in generating hypothesis and identifying variables.

The purpose of this study was to examine the effects of ill-structured problem solving program on the social self-efficacy, democratic citizenship, and meta-cognition of the scientifically gifted high school students and provide an opportunity to consider how to improve students' social self-efficacy, democratic citizenship, and meta-cognition when comprehensive character education has been emphasized in science programs for gifted students. The subjects consisted of 17 students(10th graders) and 19 students(11th graders) who were participated in a science gifted program in a Korean high school located in Seoul and pre-examination on their social self-efficacy, democratic citizenship, and meta-cognition was conducted. After applying 12-class-time of ill-structured problem solving program, post-examination on their social self-efficacy, democratic citizenship, and meta-cognition was conducted and student's self-essay about program was also conducted. Paired t-test was used to analyze the data collected and students's self-essays were also analyzed. The results of this study were as follows: First, the findings showed that ill-structured problem solving program developed students' social self-efficacy and especially showed a significant improvement in asking for help. Second, they also showed that ill-structured problem solving program raised students' democratic participation especially in a democratic function. Third, in terms of meta-cognition, ill-structured problem solving program also played a positive role. The result of analyzing students' essays also showed students' positive perception on the program. The findings of the present study suggested that ill-structured problem solving program should be taken into consideration when developing a science program for scientifically gifted high school students.

The purpose of this study is to obtain basic data for constructing a modeling practice program integrated with meta-modeling knowledge by analyzing the cognition level for each meta-modeling knowledge components through modeling practice in the context of the chemistry discipline content. A chemistry teacher conducted inquiry-based modeling practice including anomalous phenomena for 16 students in the second year of a science gifted school, and in order to analyze the cognition level for each of the three meta-modeling knowledge components such as model variability, model multiplicity, and modeling process, the inquiry notes recorded by the students and observation note recorded by the researcher were used for analysis. The recognition level was classified from 0 to 3 levels. As a result of the analysis, it was found that the cognition level of the modeling process was the highest and the cognition level of the multiplicity of the model was the lowest. The cause of the low recognitive level of model variability is closely related to students' perception of conceptual models as objective facts. The cause of the low cognitive level of model multiplicity has to do with the belief that there can only be one correct model for a given phenomenon. Students elaborated conceptual models using symbolic models such as chemical symbols, but lacked recognition of the importance of data interpretation affecting the entire modeling process. It is necessary to introduce preliminary activities that can explicitly guide the nature of the model, and guide the importance of data interpretation through specific examples. Training to consider and verify the acceptability of the proposed model from a different point of view than mine should be done through a modeling practice program.

Evidence regarding the efficacy of Ginkgo biloba extract on cognitive function has been contentious. This study evaluated the effective period of G. biloba intake to improve cognition in the elderly. PubMed, EMBASE, Cochrane, Web of Science, and PsycArticles databases were searched for short-listing relevant studies. Twenty-five studies fulfilled the inclusion criteria. Cognitive efficacy was assessed based on the duration of intervention. G. biloba intake for 3-6 months statistically significantly affected cognitive function (SMD= -0.21; 95% CI -0.39, -0.03; p=0.02). However, the improvement in activities of daily living (ADLs) was not statistically significant. Thus, G. biloba intake for more than three months improves cognition in the elderly people with cognitive impairment and AD dementia without any safety risk. Intake for up to six months does not improve ADLs significantly in mild to moderate dementia patients.
