  • 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.

  • The study was carried out to identify the relationship of patients' self-rating and nurses' rating on health literacy of hospitalized patients. Data were collected using the Korean Functional Health Literacy Test (KFHLT) which was revised for hospitalized patients and Single Item Literacy Screener. A total of 178 subjects, which consisted of 89 hospitalized patients and 89 nurses taking care of them, were recruited from medical and surgical wards of E university hospital. Collected data were analyzed using SPSS 23.0 program. The results showed that the average health literacy score of the subjects was $11.45{\pm}4.22$ out of 17 and the average correct answer rate was 67.3%. Patient health literacy was significantly different by age, education, occupation and reading handouts. The patients' self-rating had significant correlation with health literacy measured by KFHLT while nurses' rating did not. There was no significant correlation between patients' self-rating and nurses' rating. The findings suggest that patients' self-rating might be available to assess patient health literacy in hospitals and a careful approach is required when nurses use a single-item rating.
