Purpose : This study aimed to investigate the effects of blended learning on learning satisfaction in nursing students. Methods : This study was conducted with 160 current nursing students in the department of nursing at K university located in city B. All students included in the study understood the purpose of the study and provided informed consent to participate. Data were collected between May 3 and July 9, 2021 and analyzed using SPSS/WIN 22.0. The frequency, percentage, mean, and standard deviation were created, and t-test, ANOVA, and Scheffé test for post hoc analysis were performed. Correlations were analyzed using Pearson's correlation coefficient. The factors influencing learning satisfaction were analyzed using multiple regression. Results : Significant differences were observed for academic stress according to the online classes environmental satisfaction (F=4.10, p=.001), online classes experience (t=4.11, p=.001) and self-directed learning ability according to the grade (F=4.10, p=.001), online classes environmental satisfaction (t=4.11, p=.001). The academic stress of nursing students who experienced blended learning was significantly negatively correlated with self-directed learning ability (r=-.480, p<.001), and learning satisfaction (r=-.236, p<.001). self-directed learning ability showed a significant positive correlation with learning satisfaction (r=.524, p<.001). The regression model for the factors affecting the learning satisfaction of the subjects was statistically significant (F= 3.027, p<.001). The major influential factors of learning satisfaction were grade (𝛽=.154, p=.013), satisfaction with school life (𝛽=.168, p=.032), and satisfaction with non-contact learning environment (𝛽=-.141, p=.028). The explanatory power was 28 %. Conclusion : These results indicate that it is necessary to reduce academic stress and increase self-directed learning ability to enhance learning satisfaction in nursing students through blended learning.

본 논문은 2009 개정 교육과정 초등학교 3학년 수학 교과서와 익힘책에 제시된 곱셈과 나눗셈 문장제를 유형별로 분석하고, 초등학교 4학년 학생을 대상으로 문장제 유형에 따른 문제해결능력을 살펴봄으로써 곱셈과 나눗셈 문장제의 효율적인 지도 방안을 생각해보기 위한 것이다. 이를 위해 먼저 초등학교 3학년 수학 교과서와 익힘책에 제시된 자연수의 곱셈 문장제를 동수누가, 비율, 비교, 정렬, 조합의 5가지 의미 유형으로, 나눗셈은 등분제와 포함제의 2가지 유형으로 구분하여 살펴보았다. 이와 함께 곱셈과 나눗셈 문장제에서 미지수의 위치에 따라 처음량, 변화량, 결과량을 묻는 문장제의 구문 유형에 대해서도 살펴보았다. 그런 다음 4학년 학생을 대상으로 문장제 문제해결능력 검사 도구를 개발하였는데, 앞서 분석한 곱셈과 나눗셈의 문장제 유형을 의미와 구문으로 나누어 2차례의 검사를 실시하여 정답률과 학생들의 오답 반응 등을 분석하였다. 분석 결과 곱셈은 동수누가에서의 정답률이 높게 나온 반면 나눗셈의 경우 포함제와 등분제에서 차이를 보이지 않았는데, 이는 교과서의 문제 유형 분포와 상관관계를 보임을 알 수 있다. 이러한 논의를 바탕으로 곱셈과 나눗셈 문장제의 효과적인 지도와 학생들의 문장제 문제해결능력을 향상시키기 위해 다양한 유형의 문장제를 제시할 필요가 있음을 제안하고 있다.

The purpose of this study was to assess elementary student's ability of measuring length, area, and volume and reading metric scales. The findings of this study were as follows. All students were successful in measuring without scale, regardless of grades. But they were less successful in measuring the task using standard and nonstandard scales. Especially, in measuring area, lower grade students were not able to perform the task using nonstandard instruments, but higher grade students were able to perform the task. Measuring area using grade paper was least successful for sixth graders. In measuring volume, students under fifth grade read the upper scale when using graduated cylinder. In measuring by direct comparison, students were more successful in measuring length than in measuring area and volume using given material. The use of given nonstandard material was successful for 4th, 5th, and 6th grade students. In measuring using metric scale, lower grade students did not pay attention to the zero of the scale, but just read the end point. Higher grade students considered both zero and end points.

The problem solving activities developed for this formal assessment program are based on familiar, real life problems. Responses of third and fourth grade subjects to problem solving items were assessed by problem solving ability, reasoning, and imagination/creativity. Reliability of problem solving activities was supported by the results of interrater reliability and Cronbach's alpha. Correlations between problem solving activities and the Naglieri Nonverbal Ability Test(NNAT: 1985) showed that cluster scores on the NNAT were significantly related to each score on the problem solving activities. Problem solving by gender showed that girls were more likely to express ideas than boys. There were also differences related to grade level on some items.
