Penerapan Model Pembelajaran Generatif Berbantu Simulasi Physics Education Technology (Phet) untuk Meningkatkan Hasil Belajar Siswa

The research aimed to find out the results of student learning, teacher and student activities, teachers 'skills in managing learning, and students' response to the use of Generative Learning Model simulations PhET assisted in the learning process. The approach used in this study is a quantitative approach in the form of classroom action research (PTK). The research data was sourced from the students of class XI-MIA 3 SMAN 12 Banda Aceh the school year 2015/2016 totaling 29 students, 9 male students and 20 female students. Data collection instruments used in this study is the observation sheets, sheets of test in the form of pre-test and post-test at the beginning of the end of learning, and student feedback questionnaire sheets were analyzed using analysis of all three percentages. The result showed that (1) An increase in the activities of teachers and students during the learning process in each cycle, (2) There was an increase in the skills of teachers in managing learning in each cycle of the medium category to be very good, (3) The percentage of classical completeness overall well increase of 62%, 72% and 93%, and (4) the students tend to be positive where 86% of students said he was happy to learning by using model-assisted simulation generative this PhET. Based on data obtained from this study can be concluded that the application of the generative learning model-assisted simulation PhET on the material elasticity and Hooke's Law can improve learning outcomes of students of class XI-MIA 3 at SMAN 12 Banda Aceh in terms of both individual and classical completeness completeness

Penerapan Model Pembelajaran Generatif dengan Menggunakan Virtual Laboratorium untuk Meningkatkan Hasil Belajar Siswa

This study aims to find out the result of student learning, teacher and student activity, the ability of teachers in managing learning and students' response to the application of the generative learning model. This research is a type of class action (PTK) and the approach used in this research is descriptive statistical approach. The subjects of study were students of class IX.4 SMPN 8 Banda Aceh the school year 2016/2017 totaling 21 people. Data collection instruments used in this study is a test and non test. Test instruments in the form of matter pretest and posttest, whereas the non-test instrument in the form of sheets of teacher and student activity observation, sheets teacher's ability in managing learning and sheet of student responses of learning. The fourth non-test instrument are analyzed using percentages. The results showed an increase in student learning outcomes on an individual basis from 57% to 89% and classical completeness also increased from 60% to reach 87.5%. The increase also occurred in the activities of teachers and students. The ability of teachers in managing learning increases from good to be excellent category. In addition, the students' response to learning is also very well where 90% of students said he was happy of generative learning model application using the virtual laboratory. Based on this research can be concluded that the application of the generative learning model by using virtual labs can improve student learning results, increasing the activity of teachers and students, increasing the teacher's ability in managing learning in a dynamic electrical lesson

Perbandingan Hasil Belajar Fisika dengan Menggunakan Laboratorium Nyata dan Laboratorium Virtual

This research aims to know compare the results of the student in X MAN Darussalam which taught by real lab and virtual lab at Newton's Law matter. The sampling in this research were taken by using purposive sampling technique that was selected the student on X-IPA totally 20 students as the class experimental 1 and the student on X-IPA2 totally 25 students as the class experimental 2. The data obtained from tests of student learning outcomes are taught by real laboratory and virtual laboratories and data analysis techniques used by formula “uji-t”. Obtained results of data analysis based on the criterion of testing the two parties received H0 if –t(1 - 1/2 α) - ttabel and t -2.021 and 1.76 < 2.021 then declared Ho received. Based on the data analysis revealed the research hypothesis is rejected. It can be concluded that there isn't differences in physics learning outcomes are taught by real laboratory and virtual laboratories in X MAN Darussalam on Newton's laws of matter

Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study

Summary Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030
