Due to the increasing demand and importance of non-face-to-face education, open online learning platforms are getting interests both domestically and internationally. These platforms exhibit different characteristics from online courses by universities and other educational institutions. In particular, students engaged in these platforms can receive more learner autonomy, and the development of tools to assist learning is required. From the past, researchers have attempted to utilize process mining to understand realistic study behaviors and derive learning patterns. However, it has a deficiency to employ it to the open online learning platforms. Moreover, existing research has primarily focused on the process model perspective, including process model discovery, but lacks a method for the process pattern and instance perspectives. In this study, we propose a method to identify learning patterns within an open online learning platform using process mining techniques. To achieve this, we suggest three different viewpoints, e.g., model-level, variant-level, and instance-level, to comprehend the learning patterns, and various techniques are employed, such as process discovery, conformance checking, autoencoder-based clustering, and predictive approaches. To validate this method, we collected a learning log of machine learning-related courses on a domestic open education platform. The results unveiled a spaghetti-like process model that can be differentiated into a standard learning pattern and three abnormal patterns. Furthermore, as a result of deriving a pattern classification model, our model achieved a high accuracy of 0.86 when predicting the pattern of instances based on the initial 30% of the entire flow. This study contributes to systematically analyze learners' patterns using process mining.

The purpose of this study was to analyze the relevance of the school science contents that have been implemented for the 7-10th grade students in Korea since 2001. To fulfill the purpose of the study, we 1) analyzed the 7th national science curriculum of Korea, California science standards, the national science curriculum of England, Japanese national science curriculum, and current Korean and Japanese science textbooks, 2) conducted a nationwide survey in order to gather opinions from students, teachers, and science specialists. The main findings of this research were as follows: First, the number of topics presented at each grade level should be reduced and similar topics and themes should be integrated for students' deeper understanding. Second, science contents were excessive compared to the allotted teaching time and to foreign countries. Thus, the excessive overlapping and repetition of science contents should be avoided among the primary, middle and high school level, and the number of science concepts and activities should be reduced to an appropriate level considering time allotment for science classes, teachers' workload, laboratory conditions, etc. Third, to cope with the decreasing students' understanding and interests in science as school level and school year goes up, the science curriculum and textbooks should be developed to allow for student to learn science concepts by solving problems confronted in their daily lives. Fourth, a differentiated curriculum such as in-depth and supplementary course should be described not in science contents, but in teaching and learning strategy.

This study aimed to compare the eating habit, preferences, intake frequency, nutrition knowledge, and self efficacy of vegetables between middle and high school students in Busan. Subjects were 550 middle school and 560 high school students. The survey was conducted by questionnaire in May 2015. The results are as follows. About 68% of adolescents in Busan have eaten a variety of vegetables from a child. Less than 50% of them ate all vegetable dishes in school foodservice and ate three kinds of vegetable dishes at home. 40% of them did not like vegetables independent of gender and schools. They have low preferences for vegetables. More than 2/3 of them have rarely eaten green vegetables a month or twice. They have eaten more frequently white than green vegetables. They have eaten frequently yellow vegetables, but seldom purple or black vegetables. Middle school students have eaten more vegetables than high school students. Adolescents in Busan have low nutrition knowledge about vegetables. Middle school students have higher self efficacy of vegetables than high school students. Conclusively, adolescents in Busan have undesirable eating habit, low preference, and low nutrition knowledge of vegetables. Middle school students have more desirable eating habit, higher preference, more frequent intake, and higher self efficacy of vegetables than high school students. Therefore differentiated education is needed by middle and high school. It is needed urgently, especially vegetables targeted education for high school students.
