The purpose of this study was to ascertain high school student ideas on the motion of the Earth and moon by cognitive level. For this study, five students determined to be of high, middle and low cognitive level selected from 73 10th-grade students at a high school located in Suwon, Gyeonggido. The results of this study were as follows: first, students at the high cognitive level had comparatively more logical and scientific conception on the revolution and rotation of the Earth and moon. second, students at the middle cognitive level, generally had a passive learning attitude to unconditionally memorize learned contents, so they were apt to forget learned contents, also their recognized conception was not enlarged. In addition, they had native theories, intuitive ideas and misconceptions as well as made logical errors in the course of explanation for the motion of the Earth and moon. In the course of explanation for the phases of the moon and the cause of change of season, because of their scientific conception, the students made more and more errors in conception. finally students at the low cognitive level were not willing to think logically and positively and were very passive in the attitude to recognize conception. In addition, they have learned helplessness on the grounds that they have low scholastic achievement specially in science.

The purpose of this study was to develop the level-defferentiated Web Based Instruction(WBI) program, to examine its effects on the science achievement self-directed learning characteristics, and the students’ perceptions on the WBI learning. For this purpose, the advanced and complementary WBI program of level-differentiated curriculum was developed to adapt to class fields and examine instruction facilitating efficiency. Designed and developed the WBI program make it possible to teach students according to the level-differentiated learning for the chapter, ‘weather and climate’ in high school science curriculum. The results of this study are as follows: First, level-differentiated WBI was effective to encourage self-concept, learning eagerness, future-oriented self-apprehension, creativity, self-assessment of the student’s self-directed teaming characteristics. There was no interaction effect of treatment and students’ learning ability at the self-directed learning characteristics. Second, the scores of science achievement of WBI group were significantly higher than those of conventional lecture group. There was interaction effect of treatment and students’ learning ability. However level-differentiated WBI has no effect on openness, initiative, responsibility of the student’s self-directed learning characteristics. There was interaction effect of treatment and students’ learning ability at the science achievement, Third, in the perception questionnaire of WBI teaming, many students showed the WBI teaming was good in terms of causing interaction between learners and web based learning materials including various images and animations. However there are several students who showed learning difficulties. For example they wonder which part is more important and what order is proper to study in hypertext environment.

The purpose of this study is to analyze the effects of parental educational involvement and mathematical attitude perceived by students on math motivation and math anxiety. The results showed that parents' educational involvement had effect on students' motivation to learn mathematics and had a significant effect on mathematics anxiety. In addition, the parents 'mathematical attitude has a significant effect on the motivation of the students, and the higher the mathematical attitude of the parents, the lower the mathematics anxiety of the students but the higher the students' mathematics anxiety. This suggests that even if the parents are educated, the parents can influence their motivation to learn mathematics, rather the more the achievement pressure becomes, the higher the educational involvement. In addition, the parents' mathematical attitude is independent of the degree of educational involvement, and parents can expect to increase their motivation to learn mathematics by nurturing with positive and positive perceptions and attitudes. In order to do this, it is a time when parents' education for the recognition of parents' right mathematics courses and their interest in education and the role of education are positively required.

The relationship between cadmium level and mental retardation was investigated. The 297 subjects with mental retardation were drawn from two schools providing special educational services, one, consisted of children living in an orphan home, another, children with parents. The 117 control subjects were drawn from whom had got average or above average academic achivement in a general elementary school. Hair sample was taken from the nape of the neck and the cadmium and zinc analysis were carried out on an atomic absorption spectrophotometer (IL 551). Children in the retarded group had significantly higher cadmium levels compared with control but not in zinc levels. There was no relationship between metal concentrations and age except control male group, which showed significant positive linear relationship in zinc, and there was no difference between sex in both metal except the male orphan group in cadmium. In the orphan group, there was relationship between severity of retardation and cadmium concentration in both sex but not in retarded children with parents. No difference in cadmium levels between the group with Down's syndrome, one of causes of mental retardation, and the control group suggested the cadmium as a possible cause of mental retardation. In the case of accompanying autism, zinc level was significantly lower than that of other accompanying diseases. Although not establishing an etiologic relationship, findings of this study suggest that there are some influeces of cadmium on mental retardation, and call for a continuing study.

This is a descriptive study to determine the influence of character strength of nursing students on perceived stress. Data were collected from 174 nursing students in the A- area and analyzed using SPSS WIN 21.0 program. The character strength of nursing studentswas $3.46{\pm}.34$(on a 5-point scale) and perceived stress was $2.84{\pm}.42$(on a 5-point scale). Among the subdomains of character strengths, humanity was the highest,with a score of $3.65{\pm}.49$. The perceived stress of nursing students showed a negative correlation with character strength(r=-.50, p<.001) and was negatively correlated with all subdomains of character strength. In addition, the factor that most affected the perceived stress of nursing students-among general characteristics-was very difficult family experience (${\beta}=.146$, p=.026), and the factors with the greatest effect among the subdomains of character strengths were courage(${\beta}=-.250$, p=.006) and transcendence(${\beta}=-.275$, p=.013). These three factors were found to explain 39.5% of variance in perceived stress. Therefore, these results demonstrate the need to explore interventions that enable nursing school faculty and counseling staff to help confirm character strengths and reduce stress in students with hard time getting adjusted to nursing school.
