This study investigates how high school students with low academic achievement seek and use information. Participants were seven US students in an American Literature and Composition course of the $11^{th}$ grade Remedial Education Program who completed a class project that required comprehensive information seeking and use. Data were collected through comprehensive observation and individual interviews with each student, the teacher, and two library media specialists. Additionally, we gathered and analyzed the instructions the teacher and the two library media specialists provided and all documents each student produced to complete the class project. The process of data analysis was supported by QSR NVivo. The findings of the study implied that students experienced cognitive and affective challenges for their information seeking and use required for the tasks and suggested that technological and individual conferencing would motivate the students to continue their information seeking and use. We then conclude the study with some important implications that can be used as a basis for designing information literacy instructions for students with low academic achievement.

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.

This study aimed to investigate the changes in learner's scientific conceptual formation and academic achievement after a CoRe-based science lesson. For this study, two classes of the 6th grade of elementary school were divided into an experimental class and a comparison one. The students of the experimental class received CoRe-based science lesson and those of the comparison one received general science lesson. Both of the classes studied 'unit 1. A change in the weather', which is a part of content of 6th grade science text book. The results of this study were as follows. First, in the questions of invisible and abstract phenomena, students had misconceptions based on their experience in real life, or did not understand the fundamental causes of that phenomena. But after receiving lessons respectively, experimental class generally showed at a higher rate of understanding the causes of the phenomena than comparison class. Second, CoRe-based science lesson was more effective to improve students' scientific conceptual formation than the general science lesson. Moreover, when two classes were respectively divided into two groups as high and low-level groups according to their pre-test achievement records, the CoRe-based science lesson was more effective to learners of the high-level groups. Third, CoRe-based science lesson was more effective to enhance students' academic achievements than the general science lesson, especially to learners of the low-level groups.

The study was proceed to get the information how change teaching content and method in accordance with the level of academic achievement by looking at the types of errors that can occur in the four arithmetic operations of the fractions. The test paper for checking the type of errors caused by calculation of fractional was developed and gave it to students to test. And we saw the result by error rate and correct rate of fraction that is displayed in accordance with the level of academic achievement. We investigated the characteristics of the type of error in the calculation of the arithmetic operations of fractional that is displayed in accordance with the level of academic achievement. First, in the addition of the fractions, all levels of students showing the highest error rate in the calculation error. Specially, error rate in the calculation of different denominator was higher than the error rate in the calculation of same denominator Second, in the subtraction of the fractions, the high level of students have the highest rate in the calculation error and middle and low level of students have the highest rate in the conceptual error. Third, in the multiplication of the fractions, the high and middle level of students have the highest rate in the calculation error and low level of students have the highest rate in the a reciprocal error. Fourth, in the division of the fractions, all levels of students have the highest r rate in the calculation error.

This article compares the psychological and behavioral profiles of adolescents on probation and high school students. A total of 253 adolescents on probation and 257 high school students completed an open-ended questionnaire developed by the present researchers and structured questionnaire that assessed moral disengagement and self-efficacy developed by Bandura (1995), delinquent behavior and academic achievement. Adolescents on probation reported that they engaged in delinquent behavior due to the fault of others and they were angry for being forced to be on probation. They are not likely to take responsibility and morally disengage from their delinquent actions. When compared to high school students, adolescents on probation are likely to report low self-efficacy, low academic grade, and less likely to feel proud of themselves. They are more likely to meet their friends in Internet and video game rooms and less likely to focus on academic achievement. Results of ANCOVA indicate that adolescents on probation have higher scores on moral disengagement, social efficacy, but lower score on efficacy for self-regulated learning. They are more likely to run away from home and have lower academic grade. The results of the discriminant analysis indicate that running away from home, social efficacy and moral disengagement are predictive of adolescents on probation and academic achievement and efficacy for self-regulated learning are predictive of high school students.

This study investigates the effect of cloze procedure using either cartoons or texts on academic interests and reading achievements. Three equivalent classes were selected from an 1st grade in elementary school in terms of academic interests and reading achievements. While two experimental conditions used cloze procedure either with cartoons or texts during 15 lessons, the control condition used a traditional reading procedure. The results indicated that cloze procedure with cartoons enhanced academic interests in reading only for low achievement participants. Cloze procedure condition also outperformed the control condition on both immediate and delayed dictation test. In particular, cloze procedure with cartoons were quite effective for low achievement participants. Lastly, both types of cloze procedure facilitated overall comprehension test score, specifically inferential understanding test score but not factual understanding test score. Based on these findings, the types of text and learning strategy to improve academic interests and reading-related achievements were discussed.

The purpose of the study is to analyse students' academic achievement by their university major field and changes of grade. The subject was entering students of C medical graduate school in 2008. We divided entering students' major fields into two fields that are natural science and non-natural science filed. We analysed academic achievements of entering students by grades, curriculum from 2008 to 2011. And We analysed to find out whether there are differences in academic achievements by grades, curriculum of each major fields. There were no significant statistical differences in academic achievements by grade, curriculum of the two different university major fields. Futhermore, as a results of analysis on level(high, medium, low) distribution and differences of academic achievements by grade, curriculum of the two different university major fields, there were no statistically meaningful results. There is the need to keep entrance selection systems that open the possibility of selecting the students with other academic background. And there is the need to change general awareness assuming that there are differences in academic achievements by university major fields. We need to guide students with belief of their learning possibility.

The purpose of this research is to promote the academic achievement motivation and improve problem solving ability in Mathematics. In addition I hope to explore a new teaching method and facilitate students interest in mathmatics. If the teachers utilize an Internet Web Page and exchang information, the interaction activities will allow them to collect and analyse a variety of data. As this teaching method assists students motivation to get the effects of self-regulated learning strategies of students using the internet and their academic achievements and learning attitudes can be explored. The information will be gathered after the students participate in classes which were taught through the Edunet Homepage and the Department of Mathematics Homepage of KongJu National University. The Internet pages focused on the "Function" chapter of the first grade text for students attending middle school. The students were divided into two groups, experimental and comparative. Each group is composed of three levels, high, middle, and low. In the post experimental phase, two tests were administered which measured achievement ability and the learning attitude of the students. The results of the tests were then compared and analyzed. The results were as follows: First, the study demonstrated that self-regulated Learning Starategies towards Academic Achievements and Learning Attitudes were more effective than traditional teaching methods. These methods were significantly effective in the middle level and low level groups. The study demonstrated little to no improvement in the high level groups

Purpose: This study investigated sleep satisfaction and influencing factors in Korean adolescents with atopic dermatitis. Methods: Data were obtained from 4,570 subjects who completed the 2017 13th Korea Youth Risk Behavior Web-based Survey. For data analysis, descriptive statistics and multiple-sample logistic regression were used. Results: The results of this study were as follows. Gender, academic achievement, economic status, perceived stress, happiness, health status, and depression in the subjects showed a significant difference in terms of sleep satisfaction in atopic adolescents. Multiple-sample logistic regression analysis showed that male adolescents (odds ratio (OR)=0.48), academic achievement (low OR=0.67, middle OR=0.78), economic status (low OR=0.50, middle OR=0.64), lack of depression (OR=0.63), perceived stress (very OR=4.65, a little OR=2.25), perceived happiness (unhappy OR=1.99, moderate OR=1.22), perceived health status (unhealthy OR=2.17, ordinary OR=1.35), alcohol nondrinking (OR=0.75), and nonsmoking (OR=0.73) were not associated with sleep satisfaction. Conclusion: It is necessary to develop interventions that can relieve stress management and depression and develop positive emotions in atopic adolescents. In addition, there is a need to improve the environment to avoid health risks such as alcohol consumption and smoking and to minimize the effects of passive smoking.
