This study is a pre-experimental research that applied one-group pretest-posttest design to find out effects of the health assessment learning program using an online platform on the problem-solving process, critical thinking disposition, class participation, and class flow of nursing college students. Data before and after participation in the learning program using the online platform were collected from second-year nursing students who were 52 test subjects taking the health assessment and practice course at J University located in G-gun, C-buk-do. As a result of analyzing, it was found that the problem-solving process (t=-2.569, p=.013), critical thinking disposition (t=-5.363, p<.001), class participation (t=-4.429, p<.001), and class flow (t=-3.747, p<.001) were statistically significantly improved according to before and after participation in the program. Therefore, it is believed that a learning program using an online platform can be used to improve the problem-solving process, critical thinking disposition, class participation, and class flow of nursing college students during health assessment classes.

The purpose of this study is to examine the effect of the backward design reflecting the process-focused assessment on science learning achievement and science learning motivation in elementary science class. The process-focused assessment to support the growth and development of learners and the backward design that seeks a learner's complete understanding can be of great help to science learning. The results of study are as follows. First, we conducted the backward design reflecting the process-focused assessment centering on 'Earth and Moon's movement' unit, and reflecting various process-focused assessment to help achieve achievement standards. Second, as a result of science learning achievement test and science learning motivation test, there were statistically significant differences in the experimental group. It is expected that the process-focused assessment reflecting the characteristics of science subject will be utilized in the school field in conjunction with the backward design.

The purpose of this study was to examine the science writing and perception of students who experienced the argument-based claim and evidence writing approach. One hundred and eight grade 11 students were assigned to an experimental group, while 99 grade 12 students were assigned to a comparative group in their earth science classes. Students' science writings on two science topics were scored using an analytic rubric developed in this study. The comparison of experimental and comparative groups in science writing was carried out using an independent two samples t-test. Students' perception on the instruction was examined using an open-ended survey. Science writing by the experimental group scored significantly higher than that by the comparative group, except for the big idea of 'green energy'. For six concepts in 'green energy' and four concepts in 'plate tectonics, there were more students in the experimental group than the comparative group who indicated them in their science writing. Students' perception on the instruction was positive in that they mentioned planning and conducting inquiry, citing of claims and evidence, and developing inquiry questions were helpful in science learning. The results of this study imply that the argument-based claim and evidence writing approach should be implemented in science classrooms for students to develop a conceptual framework for science.

Problem solving ability, having been thought as one of the most important goals of science education is also a primary task for the current education. Indeed, the students' problem solving ability has shown almost no actual progress, despite our long accumulated science education. Under this circumstances, cooperative learning, a way to grow students' positive inter-dependence and problem solving ability in the basis of their active participation and discussion, was proposed as an effective teaching method. But, results have not consistently shown the advantage of cooperative learning over traditional learning for promoting academic achievement in science. Studies have consistently shown greater effectiveness on affective aspects. But, relatively few have focused on biology in Korea. The purpose of this study was to examine the effects of cooperative learning on the achievement and attitude of high school biology students. The pretest-posttest control group design was applied. The sample consisted of 50 11th-grade female students in experimental group(cooperative learning Student Team Achievement Division model) and 50 students in control group(traditional learning). Students in both groups recieved identical content instruction on the unit 'II. Methabolism'. These groups were treated for 13 hours during 5 weeks. Achievement data were collected using a 24-item multiple-choice test(content validity= .85). Science attitude was measured by an instrument which adapted by Kim In Hee(1994). The instrument(Cronbach $\alpha$=.89) included 40 items in four subscales: attitude toward science, social meaning of science, attitude toward science class, and scientific attitude. An analysis of covariance (ANCOVA) was used as the data analysis procedure. For the achievement data, no significant difference exists between the cooperative and traditional groups (p> .05). But, cooperative learning was effective in low-ability students(p < .05). For the science learning attitude data, cooperative learning was more effective than the traditional one(p< .05). Students in the cooperative group acheived better than those in traditional one especially in the subscale of attitude toward science class. There was no meaningful difference of the two methods in both high and average ability students, while cooperative learning was more effective than the traditional one in low ability students(p<.05).

Astronomy is the subject that can easily draw students' interest in studying science, therefore plays an important role in developing scientific core competence. However, it is difficult to develop spatial thinking that is required in understanding astronomical concepts through the classroom lessons. Planetarium, along with the science museum, is one of the most representative informal educational institution where astronomical concepts can be taught beyond time and space constraints. In this study, we developed the astronomy education program that is operated in the planetarium and applied the program to the elementary, middle and high-school students to investigate the effects of the planetarium lesson compared to the classroom lesson. The duration of this research was about 8 months, and the number of the students involved is 761, including participants of the 1 night and 2 days camps in the Daegu National Science Museum. The newly developed planetarium lesson is comparable to the previous classroom lesson of which topics are cardinal points, constellation, and the rotation of the earth. Test items were developed to evaluate the understanding of the astronomical concepts. The study was conducted based on the pre- and post-test with non-equivalent groups design comparing classroom and planetarium lessons. The results of this study are as follows. First, planetarium lesson is more effective for understanding astronomical concepts such as the cardinal points, earth's rotation, and the constellation than classroom lesson. Second, planetarium has a positive effect irrespective of gender and previous knowledge. Third, planetarium for high school students has the same effect as additional observation activities followed by the classroom instruction. Therefore, planetarium can be used as an alternative, effective tool when night observation is not available. In summary, planetarium is an effective tool that helps students to understand the astronomical concepts.

This study applied the PBL class to the 'Nursing Process and Critical Thinking' courses in the second semester of 2018, and is a primitive research that utilized a single-group, pretest-posttest experimental design in order to examine the effects of the class on Critical Thinking Disposition, Problem Solving Ability, and Professional Self-Concept. Self-report questionnaires were administered to 59 nursing college students in G province. The PBL class consisted of 8 weeks of traditional lectures and 4 weeks of PBL classes. The SPSS/WIN 23.0 program was used for data analysis. Frequency and percentage were used to analyze the general characteristics, and mean, standard deviation and paired t-test were used to analyze the difference between the two groups. As a result, the Critical thinking Disposition of nursing college students was significantly increased(t=4.39, p<.001) after PBL class(3.71±.36) than before PBL class(3.41±.40). The Problem Solving Ability was notably improved(t=3.97, p<.001) after PBL class(3.70±.59) than before PBL class(3.36±.38). The Professional Self-Concept was considerably increased(t=4.84, p<.001) after PBL class(3.22±.50) compared to before PBL class(2.92±.28). Therefore, applying Problem-Based Learning in nursing education to a greater extent is estimated to be effective in increasing the core competencies of nursing college students.
