Abstract

The implementation of the flipped classroom model was one of the efforts to prepare quality human resources and master the skills of the 21st century. Face-to-face activities that were more of an analysis, evaluating, and creating in a flipped classroom could train critical thinking skills and had a direct impact on students' understanding. The purpose of this study was to analyze the implementation of the flipped classroom model and its effect on students' understanding of the whole mount material (pollen and spore acetolysis) in microtechnique courses. This research was a quasi-experiment with nonequivalent control group design. The independent variable was the flipped classroom model, while the dependent variable was student understanding. Test (pretest and posttest) was used as data collection techniques. Data analysis was performed by calculating the N-gain then t-test. The learning design was divided into pre-class, in-class, and post-class stages. The in-class stage is designed using the practicum method. The results showed that the percentage of students with high and moderate N-gain categories in the control group was 43.76%, while in the treatment group was higher, namely 64.87%. The implementation of a flipped classroom could improve student understanding of lecture material.

Abstract

The problem of implementing biology learning in class VIIIB SMPN 3 North Batukliang 2016/2017 school year is creative thinking skills and student cognitive learning outcomes are still not satisfactory, as evidenced by the existence of MID semester scores under the KKM (Minimum completeness criteria). Caused by the learning process not running effectively because of the use of ineffective learning models. The purpose of this study was to measure the effect of the Reciprocal Teaching learning model with the Example Non Example Technique on the cognitive activities and learning outcomes of students on the subject matter of the digestive system in humans class VIII SMPN 3 North Batukliang. The instrument used in this study was an observation sheet for student learning activities and tests for student cognitive learning outcomes. The results showed that there was an increase in student learning activities, for an average student learning activity in the control class of 2.9 which was included in the quite active category, while for the experimental class by 3.5 with the active category. The results of students' cognitive learning post-test obtained an average value in the experimental class of 85.8 and a control class of 80. The t-test analysis at the significance level of 5% was obtained tcount of 3.12 while the value of ttable with dk = 54 of 2, 05. This means that the value of t is greater than the table value (3.12> 2.05). Thus it can be concluded that there is an effect of the Reciprocal Teaching learning model with the Example Non Example Technique on the cognitive learning outcomes of students.

Abstract

The purpose of this study was to assess the effectiveness of integrated local wisdom sheets for local wisdom on students' critical thinking skills. This type of pre-experimental research with the design of one groups pre-test post-test design. Samples were 18 students taken with saturated sampling technique. The instrument used was the Critical Thinking Skills Test (TKBK) with indicators: 1) interpretation; 2) analysis; 3) conclusions; 4) evaluations; 5) explanations; and 6) self-regulation. Data were analyzed descriptively and in paired sample test statistics. The results showed that the integrated inquiry wisdom local worksheet was declared effective based on the results of the N-Gain analysis with an average value of 0.65 (moderate). Indicators of interpretation and evaluation reached a percentage of 81 with a category (very high). Skills indicators explain 80 in categories (high), analysis indicators and skills conclude 60 categories (low), and the lowest percentage in self-regulation indicators reaches 37 in categories (very low). Weak skills in analyzing and making conclusions, because student self-regulation skills are low. This condition demands the need to improve self-regulation by developing cognitive monitoring through an emphasis on learning that can practice scientific curiosity skills.

Abstract

A study of the existence of Bioactive Immunosuppressant Compounds on Balinese Testis Extract (Bos sondaicus) through In Vitro Test. This study aims to study the provision of bioactive compounds immunosuppressant that has been extracted from cow testes against inhibition of lymphocyte cell ploriferation. The effects of these immunosuppressant compounds can be observed from ploriferation of Mus musculus lymphocytes cells to injections (exposure) of Bali Cow Testicular Extract exposed together or without concanavalin A (Con A, as a trigger for lymphocyte cell proliferation) and Bovine Serum Albumin (BSA) as standard solution . This research was designed with Completely Randomized Design (RAL). The data obtained were analyzed by ANOVA analysis using F-test. The results of this study indicate that injection of Balinese Cervical Test Extract exposed simultaneously with BSA (ET + BSA) can increase the proliferation of Balb / c lymphocyte cell culture in In Vitro (p <0.05) compared with control and exposure of BSA and Con A together for 72 hours. However, when exposed without Con A and BSA, the Bali Cattle Testicular Extract significantly suppressed (immunosuppressed) lymphocyte cell proliferation (p <0.05) compared with exposure to Con A.
