<p class="Abstract">Drawing – based modeling as learning approach, it allows students to create models based on drawing which help them to run a simulation. Students can use drawing–based modeling to learn a pair of interacting population known as predato–prey system while they usually conducted practicum using diagram of organisms. This study was to explore students’ argumentation and students’ understanding on the concept of the ecosystem. The study was conducted quasi – experimental using the matching – only post-test – only control group design. The participants consist of 60 grade 10 senior high school students in Subang, West Java. They are placed into two groups, 30 students in the experimental group and 30 students in the control group. Data was collected through argumentation test and selected response test for assessing students’ understanding. Students’ argumentation were analyzed using Toulmin’s argumentation pattern and statistical analysis. The result showed there is no significant difference between the experimental group and the control group for students’ argumentation. Most of the students are predominantly at level 2. But the coherency of arguments of the experimental group is more coherent than the control group. It means that the students in experimental group can make logical claim and supported by the correct and relevant grounds (data, warrant, and backing). The result of students’ understanding showed there is a significant mean score between the experimental group and the control group whether 72.33 for the experimental group and 62.13 for the control group</p>

Health education is one part of type 2 diabetes mellitus (T2DM) management. Healtheducation on T2DM has been given to patients with T2DM but has not resulted in positivebehavioral changes, seen from uncontrolled blood glucose levels and complications. Acomprehensive knowledge of T2DM, appropiate education with engaging families, can give apositive impact on comprehension and self-confidence of people with T2DM.The purpose of this study was to determine the effect of PsychoeducationMods (PM) on comprehension and self-efficacy patients with T2DM. This study uses quasyexperiment, pre and post test control group design. Respondents were patients with T2DM andtheir families who are undergoing outpatient in Dr. H. Moh. Anwar Sumenep Hospital (n = 40).Data collection used a comprehension and self-efficacy questionnaires for people withT2DM. Statistical analysis used different test with α <0,05. Mann Whitney U test result showed thatthere were differences in comprehension and self-efficacy variables between treatment group andcontrol group. Different independent sample test results in the treatment group using Paired Ttest and Wilcoxon signed rank test showed that PM improves comprehension (p = 0.007) and selfefficacy (p = 0.002) of patients with T2DM. MP needs to be applied by health personnel, especiallynurses in assisting patients with T2DM improves comprehension with the awareness and selfefficacy of patients with T2DM. Comprehension with awareness and good self efficacy with familysupport will be a reinforcing factor for the establishment of a positive behavior to control bloodglucose levels.
