ANALYSIS OF PSEUDO THINKING PROCESS SKILLS IN ELEMENTARY SCHOOL STUDENTS THROUGH ETHNOMATHEMATICS BASED PROBLEM SOLVING

This research aims to analyze process skills in pseudo-thinking through ethnomathematics-based problem solving in elementary school students. The subjects used in this research were 4 students from class IVB of SD Negeri 76 Muaro Jambi involving 4 subjects, namely 2 male and female subjects who thought pseudo-true and 2 male and female subjects who thought pseudo-false. Data collection techniques in this research used tests, interviews and documentation. Data analysis used in this research includes data reduction, data presentation, and drawing conclusions. The research procedures carried out in this research include the pre-field stage, field work stage, and data analysis stage. The results of the study stated that the four subjects showed various characteristics in using pseudo thinking patterns when answering mathematics questions. Each subject has abilities in several aspects of process skills in pseudo-true thinking, such as observing information, however, they still have shortcomings and difficulties in explaining the calculation process, communicating results, and understanding mathematical concepts as a whole. Consequently, further development is required to improve their processing skills in pseudo-thinking.

Pengaruh Model Pembelajaran Kooperatif Tipe Make A Match Terhadap Hasil Belajar Matematika Materi Luas Bangun Datar Kelas IV di SDN Kemayoran 2 Bangkalan

This research aims to determine the significant influence of the application of the make a match type cooperative learning model on mathematics learning outcomes regarding area of ​​flat figures for class IV SDN Kemayoran 2 Bangkalan. This research is a quantitative research type of experimental research, the research design used is quasi experimental design, and the form of design used is nonequivalent control group design, meaning that neither the experimental group nor the control group samples were chosen randomly. The sample used was 56 students at SDN Kemayoran 2 Bangkalan consisting of class IVA and class IVB. This research uses an experimental class and a control class. Data collected using observation, interviews and tests. Trials on test instruments use validity tests, reliability tests, level of difficulty of questions, and distinguishing power. The data analysis used is a prerequisite test using the normality test, homogeneity test, and hypothesis testing using the Mann Whitney test. Researchers used the Mann Whitney hypothesis test because based on the results of the normality test, the data was not normally distributed. So to compare data from two groups of data (experimental and control) you must use the non-parametric Mann Whitney test. Based on the results of data analysis in hypothesis testing using Mann Whitney, the posttest obtained on the Mann Whitney line was U = 269.5 and Pvalue = 0.039/2 = 0.02. According to Kadir (2015), if pvalue < 0.05 then Ho is rejected. So it can be concluded that there is a difference in the average value of mathematics learning outcomes between the control and experimental classes

PENGARUH MEDIA VIDEO ANIMASI TERHADAP PEMAHAMAN KONSEP IPA SISWA KELAS IV SEKOLAH DASAR

Many elementary school students have low conceptual understanding, it is because students do not absorb learning well, and one of the factors is the lack of learning media. Therefore, it is necessary to use more interactive learning media such as animated video media. This study aims to determine the effect of animated video media on students' understanding of science concepts. This research was conducted at SDN Kebon Besar 1. The method applied in this study is quantitative in the form of quasi-experiments. The population of this study was all grade IV students totaling 56 students, which were divided into two (2), namely class IVA as a control class using conventional learning methods and class IVB as an experimental class using animated videos. The data collection technique was in the form of a test (pretest-posttest). Hypothesis testing carried out with a t-test on the posttest test with a significance level of ? = 0.05 found Sig. (2-tailed) = 0.000 which means H0 is rejected and H1 is accepted. It can be concluded that animated video media has an effect on students' understanding of science concepts.

Refining Field Cancerization: An Institutional Cohort Analysis of Patient Characteristics in a Validation Cohort.

Field cancerization is poorly defined in dermatology. The author group previously proposed and applied a classification system in an original cohort to risk-stratify patients with field cancerization. Apply the authors' classification system within a validation cohort. Patients with keratinocyte carcinoma history completed a survey regarding demographic information, medical history, and chemoprevention use. Patients were assigned a field cancerization class, and differences between validation and original cohorts were assessed. A total of 363 patients were enrolled (mean age 67.4; 61.7% male). After comparing validation and original cohorts, there were differences in age between class II (p = .02) and class IVb (p = .047), and differences in chemoprevention use in class III (p = .04). Similar to the original cohort, the validation cohort was associated with increases in total number of skin cancers in the last year (p < .001), 5 years (p < .001), lifetime (p < .001), years since first skin cancer (p < .001), and chemoprevention use (p < .001). In the validation cohort, there were increases in age (p = .03) and immunocompromised status (p = .04) with increasing class, which were not observed in the original cohort. Differences among field cancerization classes were similar in a validation cohort, further highlighting the importance of class-specific treatment and management.

Ovarian cancer management in an ESGO ovarian cancer center of excellence: a systematic case study of the interprofessional and interdisciplinary interaction

PurposeWith growing knowledge about ovarian cancer over the last decades, diagnosis, evaluation and treatment of ovarian cancer patients have become highly specialized, and an individually adapted approach should be made in each woman by interdisciplinary cooperation. The present study aims to show the variety and extent of medical specialties involved at our institution according to the European Society of Gynecologic Oncology (ESGO) Quality indicators (QI).MethodsA woman, diagnosed with high-grade ovarian cancer, International Federation of Gynecology and Obstetrics (FIGO) class IVb was selected for a single case observational study. The observation period (total = 22d) comprised preoperative diagnostic procedures, including imaging, the in-patient stay for cytoreductive surgery, and the postoperative course and case discussion at our interdisciplinary tumor board. Data were obtained by self-reporting and by patient file review.ResultsPatient tracking demonstrated an interdisciplinary cooperation of 12 medical specialties [62 physicians (63% male, 37% female)], 8 different types of nursing staff [n = 59 (22% male, 78% female)], and 9 different types of perioperative/administrative staff (n = 23; male 17,4%, female n = 19, 82,6%). Contact with the patient was direct (n = 199; 76%) or without face-to-face interaction (n = 63; 24%).ConclusionThe present study demonstrates the high diversity of physicians and the affiliated medical staff, as well as interdisciplinary intersections within teams of a specialized hospital. Matching the ESGO QIs, this report underlines the requirement of an adequate infrastructure for the complex management of advanced ovarian cancer patients.Future prospective studies are warranted to evaluate the specific procedures and actions to optimize the interprofessional and interdisciplinary workflows.
