The purpose of this research was to examine the attitudes toward science on geology and satisfaction of education according to the stage of cognitive development of middle school students mainly on the geoscience education program of IS-GEO(International School for Geoscience and Mineral Resources) which is the KIGAM(Korea Institute of Geoscience and Mineral Resources) and to see what kind of correlation it shows between these. The subjects of research are 139 out of 282 students who participated in the geoscience education program conducted at the IS-GEO which is a KIGAM in 2018 by random sampling. Therefore, the research results are as follows. First, the concrete operational stage was 44%, the transition stage was 32%, the formal operational stage was 24%, 76% of the middle school student's cognitive development level didn't reach at the formal operational stage. Also, attitudes towards science on geology indicated statistically significant differences in the sub-region in "Geology-related science class", "Suburban geological science class", "Recognition of geological science and technology". Second, there was no statistically significant difference in educational satisfaction depending on the stages of every cognitive development. In other words, all participants at the cognitive stages showed high satisfaction with the geological education program which progresses at the IS-GEO, which is the KIGAM. Third, the correlation between educational satisfaction and attitudes toward science on geology showed a statistically meaningful static correlation. Therefore, attitudes toward science on geology can be positively displayed that participants who participated in geoscience education program and training of the IS-GEO have high satisfaction of education in science behavioral system.

The purpose of this study was to investigate cognitive acceleration effect of the experimental group over three years compared with the control group through the ‘Thinking Science' program in the middle school students. The ‘Thinking Science' program was implemented to 168 students in 7th grade over a period of two years. After implementation of the ‘Thinking Science' program, the improvement of formal thinking ability of the students was almost twice examined with SRT VII as the post-test and the delayed test. It was shown that by the end of the implementation period the experimental group had achieved a significantly greater gain score in levels of cognitive development than had the control group. In the subsequent year during which there was no further implementation, the experimental group continued to develop at the same rate as the control group. However, it is clear that much more experimental students in mature concrete operational stage shifted to formal operational stage in delayed test. The results were also analyzed by gender, and cognitive levels of the students. In the post-test, the ratio of girls that shifted to formal operation stage in the experimental group increased as compared with the ratio of boys, while, in the delayed test cognitive level of boys was more effective than that of girls.

This paper examines the cross-sectional development of children's conception of place. Previous research by Piaget and Weil, Jahoda, Daggs has questioned how young children develop the ablity to comprehend place. Oral interview and graphic test were made vy the children at the age of 5-14, in order to attain information on their knowledge, understanding and feeling about place. These data were used ti indentify developmental stages through cluster analysis. The results suggest that young children's conception of place develops with an identifiable 4 stages. There is no significant difference in development of conception of place between the 2nd year of kindergarten and the 1st year of elementary school, or the between the 5th, 6th year of elementary school and 1st, 2nd year of middle school. Rather, the 4th year of elementary school is an important and crucial truning point in the development of children's conception of place. It is concluded that children's conception of place develops in line with Piaget's general cognitive developmental theory in which the pre-conceptual stage ends at age 7 and the concrete-operation stage starts at age 11 to 12.

The purpose of this study is to identify factors that affect the language development of infants. For the analysis, data of three years from the first year (2008) to the third year (2010) of the 'Panel Study on Korean Children (PSKC)' were constructed and panel analysis was conducted. The subjects were 2,150 infants who participated in the questionnaire, and the language development of the infants was measured using the communication scores of the K-ASQ test provided by the Korean children's panel. In addition, the factors influencing the language development of infants derived from previous studies were introduced into the model. As a result of the analysis, it is shown that the fixed effect model with fixed individual error of the panel is suitable through the Hausman test. The higher the cognitive development level of the infant, the more positive parenting behavior of the infant, respectively. The conclusions and suggestions about the characteristics of the parents and the parents affecting language development were introduced.

This study investigates aspects of the zone of proximal development (ZPD), the distance between the actual development and the potential development. Out of 18 university students taking a geometry course, two students with the same actual developmental level in the van Hiele model in the pre-test and post-test were interviewed for measuring their potential developmental level. Based on the communicational approach to cognition, the characteristics of the two interviewees' discourse on 3D reflective symmetry were identified. There were considerable differences between the two interviewees in terms of their potential developmental level. Methodological implications for how to investigate students' ZPD in mathematics education research were addressed.

The purpose of this study is to investigate the process of development of explanatory hypothesis being generated by middle school students and the factors that affect the process in water wave interference phenomena by analogy scaffolding. For this purpose, the processes on how explanatory hypotheses were generated, revised, and then elaborated by analogy scaffolding were investigated and analyzed. The subjects for the study were 60 eighth grades students in one middle school divided into 12 groups according to their cognitive level measured by GALT. The research findings are as follows: First, it was found that there is a regular pattern in development of explanatory hypothesis by students about water wave phenomenon; second, the cognitive level of the student affected apparently on the students' hypothesis development process, however, it was also observed that students with inferior cognitive level could form a scientific explanatory hypothesis in the second stage of the scaffolding; third, the analogy scaffolding actually helped the students in formulating hypothesis. In conclusion, analogical reasoning can be a meaningful and powerful strategy for secondary school students to formulate explanatory hypothesis.

Bullying is the intentional, unprovoked abuse of power by one or more children to inflict pain on or cause distress to another child on repeated occasions. Bullying can be considered to be a form of child abuse：peer abuse. Victims suffer adverse effects in the short and long term. If bullying is regarded as a form of abuse then professionals have a duty to detect it, take it seriously, and ensure that it is deal with to reduce the child's suffering and minimize the potential long term effects. This study is aimed preliminarily the development of cognitive behavioral group therapy for school bullied. 202 normal middle school freshman responded to self report scales- Offer's Self-Image Questionnaire-Revised, Children's Depression Inventory, Spielberger State/Trait Anxiety scale, and Defining Issues Test. The data were analyzed with Pearson's correlation to test the relationship among the above 4 variables. Self Image, depression, and anxiety were correlated strongly each other. But moral development was not correlated with self image, depression, and anxiety. Five school bullied students were referred by their teacher for school maladjustment. The author tried 12 sessions of Cognitive-Behavioral group therapy and assessed their behaviors pre- and post intervention by above 4 scales. There were no significant different intervention effects statistically. But It is meaningful that improvement of psychological mindedness in diary written by subject in treatment sessions

Assessment in music therapy is a vital part for both the therapist and client in the process of therapy. Based on what is assessed, objectives are identified to formulate specific action procedures and strategies. The existing assessment tools involve lists of skills and behaviors in developmental domains without the music assessment protocol. In this study, the authors attempted to develop an assessment protocol using rhythm production for assessing skills in cognitive and emotional-behavior domain, namely Music Therapy Assessment for Cognitive and Emotional Behaviors (MACEB). The test items of the MACEB-Rhythm were developed using rhythmic patterns varying in terms of item difficulty, which are based on the various degree of clarity in the grouping/gestalt, saliency in part-whole relationship, and complexity in repetition vs. variability. Also the developed tool purported to examine one's level of emotional behavior trait by analyzing performance of musical parameters such as tempo, pacing, and loudness in the reproduced output. In order to verify the logical sequencing of test items, firstly 61 subjects participated in verifying the item difficulty for the selected 15 pilot items. The test items were revised and re-sequenced based on the gathered scores of item difficulty. In the second procedure, seven experts in the fields of music education, music therapy and music psychology whose research interest lie in music cognition revised the developed rhythm protocol items focusing on learning sequence, cognitive process and feasibility for skills assessment. The study attempted to provide foundations for using rhythm as an assessment protocol prior to its verification of assessment validity and reliability.

This study is based upon the survey for the GALT(Group Assessment of Logical Thinking) full version and short version used in the science education researches for investigating the cognitive levels of students in secondary schools. The main discussions include the annual trends of two GALT versions appeared in the research papers, the distributions of the students' cognitive levels obtained by two GALT versions, the purposes of the GALT used in the researches, and the results of two GALT versions applied to the same group of high school students. The summarized results are as follows. The frequency of the GALT short version used in the research papers has been increased recently relative to that of the full version. For the same grade students, the fraction of students in the formal operational cognitive level obtained from the GALT short version was always bigger than those obtained from the full version. The purposes of the GALT employed in the researches are classified into two groups. One group includes the papers in which the subjects were subgrouped into three cognitive levels from GALT results and it was used as an independent variable to analyze the dependent variable. In this case, the analyzed results might be altered depending on the version of GALT used. The other one includes the papers in which the GALT results were used as a covariable or the GALT scores were used directly without subgrouping the subjects by cognitive levels. For this group, the research results would not depend on the GALT version. When both of the GALT versions were tested on the same group of students with two months interval, the fraction of formal operational level obtained from the short version was bigger than that obtained from the full version.
