Abstract

This research aims to investigate the impact of the Discovery Learning model on students' scientific literacy skills in ecology at SMP Negeri 1 Delitua. The research method used was quantitative with a sample of 66 students from classes VII-5 and VII-6, selected using a purposive sampling technique. The instrument used is a scientific literacy test, with the independent variable (Discovery Learning model and direct learning model) and the dependent variable is students' scientific literacy abilities. The results of the research show that the application of the Discovery Learning model has a significant influence on the scientific literacy abilities of class VII-5 students who are at level 2 with a score of 31, which is in the poor category. However, after implementing the Discovery Learning model, scientific literacy ability increased to level 4 with a score of 69 and was included in the sufficient category.In conclusion, the application of the Discovery Learning model is effective in improving students' literacy skills on ecological material in class VII-5 SMP Negeri 1 Delitua. This finding provides an important implication for the development of a more problem-oriented student learning approach in improving students' science literacy.

Abstract

Learning at UPT SMPN 1 Sutera seems to be still low, this is because the learning model used by teachers is still not appropriate and the discussion process has not been carried out well. One way to overcome this problem is to apply the STEM integrated Problem-Based Learning (PBL) model. This research aims to determine the effect of the STEM integrated Problem-Based Learning (PBL) model on student learning outcomes in human respiratory and excretory system material at UPT SMPN 1 Sutera. The type of research used in the research is Quasi Experiment, namely a research method to find the effect of certain treatments on others under controlled conditions. The design used in this research is the Non-Equivalent Control Group Design. The population in this study were class VIII students at UPT SMPN 1 Sutera. The sample in this study consisted of two classes, namely the experimental class and the control class which were taken using a purposive sampling technique. The instruments used consisted of an observation sheet on the implementation of the STEM integrated PBL model, pre-test and post-test questions. The research data obtained was then analyzed through descriptive statistical tests and inferential statistics using SPSS version 25. Based on the results of the analysis in hypothesis testing, it showed that there was a significant average difference between the control and experimental classes. The results of research hypothesis testing were found to be 0.000 and smaller than 0.05. Thus, it can be seen that the significant difference between Ha is accepted and H0 is rejected, so there is an influence. The conclusion from the hypothesis test is that there is a significant influence between students' scores using the STEM integrated PBL learning model. So H0 is rejected and Ha is accepted. So there is an influence of the STEM integrated PBL model on student learning outcomes.

Abstract

The background of this research was the results of the researcher's observations on 8th grade students of SMPN 14 Padang. Based on the results of observations, information was obtained that teachers had previously implemented the PjBL learning model but never had implemented the STEM approach, and teachers had never combined the learning model with the STEM approach. The purpose this research was to examine the effect of the PjBL-STEM learning model on students' cognitive skill regarding substances and their changes subject. The type of research used was Quasi Experimental, design, using a Posttest Control Group Design. This research used two classes, there were experimental and the control class. The experimental class uses the PjBL-STEM learning model, while the control class used a conventional approach learning model. Sampling in this study was carried out using a purposive sampling technique, based on almost the similliary average daily test scores. The instrument of this research were multiple choice test with 20 questions. The results of data analysis show that the cognitive skill of students in the experimental class are higher than those in the control class. The used of the PjBL-STEM learning model makes a good difference in students' cognitive abilities. The results of hypothesis testing based on posttest data obtained from the two sample classes showed that, H0 was rejected and H1 was accepted, so it can be interpreted that there is a difference in the average cognitive abilities of students in the experimental class and the control class. There is an effect of the application of the PjBL-STEM learning model on the students™ cognitive skill on substance material and its changes subject.

Abstract

Low student communication skills have been the cause of this research, which had an impact on learning outcomes because there had not been training on students' communication skills through the application of appropriate learning models. The learning process, which still uses conventional learning models, namely group discussions, has not made each student active and responsible for group assignments and has not trained communication skills in scientific arguments. Therefore, an appropriate learning model is needed, one of which is the Numbered Head Together (NHT) type cooperative learning model. The aim of the research is to determine the effect of implementing the NHT type cooperative learning model on the communication skills of SMPN 3 Tebo students. The research uses a Quasi-Experimental type of research with a Nonequivalent Control Group Design. The research began with a pretest in the experimental class and control class, then treatment was given to the experimental class, and at the end of the learning process, a posttest was given to both classes. Samples were taken using purposive sampling technique. The test instrument consists of 13 description questions. Data were analyzed using Microsoft Excel to carry out prerequisite tests and hypothesis tests on overall communication skills and each ability indicator. The results of the research showed that there was an increase in students' overall communication skills between before and after treatment. Through the Mann Whitney test with Zcount -5.32 and Ztabel 1.96 with the criterion that H0 is accepted if “Ztabel ≤ Zcount ≤ Ztabel, then Zcount -5.32 < -Ztabel -1.96, then H0 is rejected, and H1 is accepted. It can be concluded that there is a significant influence of implementing the Numbered Head Together type learning model on the communication skills of students at SMP Negeri 3 Tebo Regency.
