Abstract

Various types of models student-centered learning has increase for this time. In addition to appropriate learning models, use media for learning is expected to improve student achievement. The purpose of this research is to determine whether the learning achievement student by using media power point in cooperative learning NHT better than just using cooperative learning NHT without media on the subject of hydrocarbons. The study population was the whole class X SMA Teladan with totaling 3 class. Samples were taken at random as much as 2 class and consists of 72 students. The data of student achievement in Chemistry obtained by providing multiple-choice test with 20 questions. Hypothesis testing is done right part t-test at a significance level of = 0.05. Results of data analysis obtained by the average value of the students taught using media power point and a model cooperative pembelajran NHT (class eksperimen1) was 72.08 ± 13.80 with an increase of 56.67%, while the average value of the students taught by implementing cooperative learning NHT (class eksperimen2) was 65.28 ± 9.41 to 40.56% increase. The results showed that an treatment by using media power point on cooperative learning model NHT better than the treatment only implement cooperative learning model NHT to improve student’s achievement in Chemistry, with t-test (2.739) > t table (1.66883) for α = 0.05 and df = 68.

Abstract

The outbreak of the corona virus (covid-19) in Indonesia which continued to increase until early March 2020, eventually led the government to impose a large-scale system of social restrictions (PSBB) in the DKI Jakarta area and several other regions. The implementation of this system also automatically encourages education practitioners to carry out online learning. Teachers and students are forced to be ready in their implementation, although so far some schools have never done learning with an online system. Through this research, the researcher wants to analyze how effective the implementation of the learning system is from the teacher's perspective. The sample of this study was 35 teachers who teach at the primary school level from public and private schools in the North Jakarta area. The instrument used was a questionnaire distributed online using the ms.form link. Based on the data obtained, shows that the implementation of online learning has been carried out effectively seen from the readiness of the teacher, the ability to use applications, responses and benefits obtained
