This study used a quasi-experimental design with a pretest-posttest control group. The research population was 288 students of class VIII, and 64 students were selected as research samples consisting of 32 students of class VIII Apples as the control class and 32 students of class VIII of Mangosteen as the experimental class. The two classes were selected by purposive sampling, where the consideration was the similarity of the characteristics of the students (homogeneous)—collecting data using observation questionnaires of scientific attitudes and students' scientific work. The research data were analyzed using the Mann Whitney test because the normality test results were not normally distributed. Thus the correlation test uses the Spearman correlation test. The research data shows an influence of the STEM Approach in the Guided Inquiry Learning model on students' scientific attitudes and scientific work. Based on the Spearman correlation test conducted on scientific attitudes and scientific work in the experimental class, a value of 0.664 was obtained with a significance of 0.000 < 0.005, meaning that the relationship between scientific attitude and scientific work was strong. The correlation coefficient of scientific attitude and scientific work in the control class is 0.818 with a significance of 0.000 < 0.005, meaning that there is a strong influence of the guided inquiry model on scientific attitudes and scientific work. A good scientific attitude will make students' scientific work better. The STEM approach in the guided inquiry learning model is superior to making students' scientific attitudes and scientific work better than those without using the STEM approach.

Abstract The ability to understand concepts is very important and becomes the basis for supporting the solving of mathematical problems. The connection between one concept and another concept and one topic with another topic is a characteristic of learning mathematics. The relationship requires that each student must have the ability to understand the concepts well, but it cannot be denied that the ability to understand mathematical concepts is still low, as happened to theLangke Rembong 4Junior High School students. Learning innovation needs to be done to achieve a good understanding of concepts. This study aims to compare the understanding ability of mathematical concepts of students who follow a guided inquiry learning model with students who take direct learning. The research design uses Posttest only control group design. The population is all eighth grade students of Langke Rembong 4 Junior High School, totalling230 students. Sampling is done by random sampling with equality test between classes.It is then obtained class VIII A as the experimental class and class VIII C as the control class. Data collection uses tests in the form of description questions. Data analysis uses t-test with normality test and homogeneity test for the assumptions. The results show that the students who follow the guided inquiry learning have higher understanding of  mathematical concepts than those who are taught with direct learning model.

Objective: The aim of this study was to investigate the levels of Human Beta Defensin (hBD) 2 and 3, chemokine and cytokine expressions between teeth endodontically diagnosed with symptomatic irreversible pulpitis (SIP), asymptomatic irreversible pulpitis (ASIP) and normal pulps. We hypothesized that there would be a correlation between hBD’s and the immunoregulatory response. Design: Pulpal samples were collected with paper points. Six samples were obtained from normal teeth, 21 from SIP, 18 from ASIP. Levels of cytokines and betadefensins were measured by Luminex technology and ELISA, respectively. Data were statistically analyzed using Kruskal-Wallis, Wilcoxon Mann-Whitney test and Spearman correlation test. Differences were considered significant at p<0.05. Results: hBD-2 levels correlated with samples obtained from patients in the ASIP group, but not in the samples obtained from patients with SIP or the control group. HBD-3 concentrations associated with all of the cytokines and chemokines in both SIP and ASIP groups. However, in the normal group, hBD-3 correlated with only TNFα, IL-8, MCP-1, IL-1β, MIP-1a, RANTES, IL-17 in normal group. When comparing control levels of hBD-2 and hBD-3 with patients samples from either the ASIP or the SIP groups, hBD-2 and hBD-3 concentrations were highest in the ASIP group. Conclusions: The hBD-2 and-3 were highly associated with the levels of the chemokines and cytokines in ASIP group. HBD-3 concentrations correlate with the levels of the chemokines and the cytokines in the SIP and ASIP groups.
