  • The purpose of this study is to examine epistemic thinking in middle school students in an argument-based inquiry science class. Participants of the study were 93 9th grade students from four classes of a middle school in a metropolitan city. Observations were made over one semester during which argument-based inquiry lessons on five subjects were conducted. Data was collected from argument-based inquiry activity worksheets and student questionnaires. After analysis of epistemic thinking in the written reflections, students were found to have the highest frequency of epistemic metacognitive skills, followed by epistemic cognition, epistemic metacognitive experience, and epistemic metacognitive knowledge. While investigating the effects of an argument-based inquiry science class on student epistemic thinking and after analysis of the reflections written for the first ABI activity and the fifth ABI activity, we found that all of the sub-elements of epistemic thinking have increased. The rate of growth for epistemic cognition is greatest, followed by epistemic metacognitive knowledge and epistemic metacognitive skills. Assessed for epistemic thinking, the level of epistemic thinking improved over the course of the argument-based inquiry science class. The results of the survey show that students actively participating and being recognized for their active participation in the argument-based inquiry science class are helpful in understanding scientific knowledge. Therefore, an argument-based inquiry science class is a teaching and learning program that allows students to understand and experience the epistemic nature of scientific knowledge and its construction through collaboration and agreement.

  • The current study aimed to examine the gender differences in trajectories of nine successful aging indicators (chronic disease, depression, activities of daily living, instrumental activities of daily living, mini mental state examination, social activity, personal contact, health satisfaction, and general life satisfaction) with age, controlling the effect of education. The data were from the Korean Longitudinal Study of Aging, which had been conducted biennially from 2006 to 2016. The sample included 822 men and 1,236 women who responded to all of the panel surveys and were 65 years old or above in 2006. Multilevel modeling analyses showed that older men had fewer chronic diseases; lower levels of depression; higher levels of activities of daily living, cognitive function, and social activity; and better perceived health satisfaction and general life satisfaction at age 65 years compared to women. However, both men and women showed increase in the number of chronic diseases and depression level, and decrease in physical, cognitive, and social functions with age. In addition, perceived health and life satisfaction also decreased after the age of 65. The trajectories of most of the indicators were non-linear, and markedly increased or decreased around mid-70s. Study limitations and implications were further discussed.

  • There has been a growing number of research about children's development indicators and child well-being indicators. After the Convention on the Rights of the Child (CRC) and concluding observations on the second report of Korea, the effort to monitor and measure children's rights and the use of child rights indicators has increased within policy and academic research. However, few indicators provide a realization of children's rights. The purpose of this paper was to analyze children's own perceptions of their rights and to develop a children's rights index to measure children's rights. In this study, a children's rights index was developed from 38 indicators categorized into nine components and four domains (survival rights, development rights, protection rights, and participation rights) to measure children's rights. Data were gathered from 17,000 elementary and middle school children and their parents in 16 cities. The survey revealed significant differences in the children's rights index by region and age group. There was also a correlation between the economic circumstances of both households and communities and the children's rights index. In the light of the findings, it is suggested that there is a need to increase public investment on children and to raise awareness of children's rights in order to improve children's rights and to decrease disparity.

  • This study analyzes the epistemic considerations and the argumentation level revealed in the discourse of the key concept of natural selection for science-gifted elementary students. The paper analyzes and discusses the results of a three-student focus group, drawn from a cohort of twenty gifted sixth-grade elementary students. Nature, generality, justification, and audience were used to analyze epistemic consideration. Learning progression in scientific argumentation including argument construction and critique was used to analyze students' scientific argumentation level. The findings are as follows: First, Epistemic considerations in discourse varied between key concepts of natural selection discussed. The nature aspect of epistemic considerations is highly expressed in the discourse for all natural selection key concepts. But the level of generality, justification and audience was high or low, and the level was not revealed in the discourse. In the heredity of variation, which is highly expressed in terms of generality of knowledge, the linkage with various phenomena against the acquired character generated a variety of ideas. These ideas were used to facilitate engagement in argumentation, so that all three students showed the level of argumentation of suggestions of counter-critique. Second, students tried to explain the process of speciation by using concepts that were high in practical epistemic considerations level when explaining the concept of speciation, which is the final natural selection key concept. Conversely, the concept of low level of epistemic considerations was not included as an explanation factor. The results of this study suggest that students need to analyze specific factors to understand why epistemological decisions are made by students and how epistemological resources are used according to context through various epistemological resources. Analysis of various factors influencing epistemological decisions can be a mediator of the instructor who can improve the quality and level of the argumentation.

  • With broad individual variability in social communication skills of children with autism spectrum disorders and increasing focus on interventions targeting social communication of this population, there is a need for systematic analysis of how social communication outcomes are measured. This study aimed to systematically analyze the measurement tools used in the music therapy interventions for improving social communication of children with ASD. Electronic databases and music therapy journals were searched for controlled studies published between 1980 and 2015. A total of 21 studies were included for the analysis. The results demonstrated that direct observation of behaviors was the most frequently used and the combination of targeted social communication areas and specific measurements used for a specific skill varied among the studies. In addition, 90.4% of studies reported interrater reliability. These results indicate that there has been a diversity in approaches to measure social communication skills despite increasing attempts for systematic measurements. In consideration of the nature of social communication development in children with ASD, multifaceted strategy to understand and assess the target skills in terms of specific behavior acquisition, social functioning in general, and social cognition was recommended.

  • The purpose of this study is to figure out the characteristics of teacher's scaffolding that can promote the social construction of scientific models by analyzing a teacher's scaffolding that actually promoted the social construction in a real classroom context, so that we can better understand the teacher's scaffolding. For this study, a total of 32 middle school students and their science teacher in Seoul were observed and videotaped. The level of social construction were categorized in four stages. We divided the teacher's scaffolding by whether the level of social construction has changed or not, and analyzed teacher's scaffolding in each group. Teacher's scaffolding were categorized based on its object, purpose and means. The object were categorized into two types; small-group and individual. The purpose were categorized into two types; process-help and product-help. The means were coded into Diagnostic strategies(Reading, Listening, Questioning), Checking diagnosis and Intervention strategy(Instruct, Explain, Hint, Confirm). The result show that teacher's scaffolding is helpful in the social construction of scientific models when it supports small-groups more than individuals, and process-help more than product-help. It also shows that in diagnostic strategies, questioning and listening are effective. Finally, using checking diagnosis promoted interactions among students and a 'confirm' intervention strategy should be avoided because it has no positive effect on changes in the level of social construction. This study provides the features of the teacher's scaffolding that promotes social construction of scientific models in middle school classes.

  • The significant role of joint attention in the development of children with autism spectrum disorder (ASD) has highlighted the importance of early intervention. With the emphasis on the effective cueing and reinforcer for orienting to social stimuli in improving responding to joint attention (RJA) of children with ASD, the use of musical cue was hypothesized. This study aimed to examine the occurrence of RJA behaviors depending on the attentional cue, which differed in the level of information and type of auditory modality. Nine children with ASD participated in this study. The use of eight different joint attention cues were analyzed in terms of the frequency and accuracy of RJA behaviors elicited. The results of the study showed that RJA behaviors occurred more frequently with musical cues than with verbal cues and the mean accuracy rate of RJA was higher with musical cues (p = .047). Musically delivered eliciting and directing cues accompanied with pointing elicited the highest attentional shift and RJA accuracy. The significant increases in RJA with the use of musical cues indicated that incorporating musical elements into an attentional cue may provide more accurate cue information, enough to improve RJA behaviors of children with autism.

  • Objective : The purpose of this study was to identify the status and trends of Korean child occupational therapy intervention studies according to the International Classification of Functioning, Disability, and Health, Children and Youth Version (ICF-CY). Methods : In this research, 47 studies on occupational therapy interventions for children that were published between January 2017 and December 2021 in the Journal of Occupational Therapy, registered in the Korea Citation Index, and analyzed the classification of the study type and evidence level to understand the trends. Moreover, intervention objectives and approaches were analyzed on the basis of the ICF-CY. Results : The outcomes of the analysis of the articles published in the Journal of Occupational Therapy were as follows: (1) Level IV was the highest evidence level (53.19%). (2) Among the studies, most (53.7%) included school-age children as subjects. Autism spectrum disorders and developmental delays were the most common diagnoses (14.8%). (3) As for the purpose of intervention according to ICF-CY, activity and participation factors were the most common (48.94%), and a sensory approach was frequently used. Conclusion : This study reviewed articles on occupational therapies for children that were published in the Journal of Occupational Therapy to understand the trends in occupational therapy interventions for children in South Korea. For the development of occupational therapies for children in the future, more qualitative research types and studies on various intervention approaches are needed.

  • Because of a rising in the standard of living and the development of medical technology, Korea is expected to become an aging society more than 14% elderly population and the silver generation will be responsible for the large portion of economic activities. The silver generation has relatively diminished in perception, learning, and exercise due to the physical aging. Therefore, it is important the development of game contents which can constantly provide the maintenance function of physical and mental health and the functional exercise with spending the leisure time. In this paper, we suggest a design method for developing the game contents which are able to help the silver generation to strengthen their lower extremities and to enjoy their leisure time. The proposed method will enable to lead the silver generation to carry on the physical activities with the amusement of playing a game through the functional design concepts appropriate for the ability of the silver generation's perception and physical activities, an adaptive game process customized by the individual capability and a user-friendly sensory interface.
