Mathematical communication skills of students are still relatively low. One learning model can improve students 'mathematical communication skills and at the same time students' mathematical disposition is the Problem Based Learning (PBL) model. The aim to be achieved is to find out the improvement of students 'mathematical communication skills and mathematical disposition using PBL models in terms of students' initial mathematical level. This research is an experimental research design with pretest posttest control group design. The research population was Grade VII students of SMP 9 Langsa. Students are grouped into two classes namely the experimental class and the control class randomly selected from eight parallel classes. The instrument used was a test of mathematical communication skills and a mathematical disposition questionnaire. Data analysis was performed using two-way ANOVA. The results showed that improving students 'mathematical communication ability and students' mathematical disposition by applying PBL learning models is better than students applying conventional learning models. There is no interaction between the PBL learning model with student level on mathematical communication skills and students' mathematical disposition.

Realistic Problem

Problem-based learning has been well-documented, from its early days in the teaching of medical professionals to its more recent use in other disciplines. It has been adopted in many educational institutions because it gives students a realistic problem and provides opportunities to translate knowledge into solutions. This article is a case study of this approach at a second-year technical course, in which members of the class were divided into groups and given a scenario concerning a fictitious organisation about to embark on a major upgrade to its existing and problematic networking infrastructure. The course consisted of two parts. The first group was provided with a set of virtual machines to upgrade, and the second group chose and implemented a major technology on this newly upgraded network. The authors outline how problem-based learning is used in this context in a way that informs the teaching of any technical computing course.

This article reports on the achievement and attitude aspects of a study comparing students who had the first 4 years of the University of Chicago School Mathematics Project (UCSMP) secondary curriculum to two distinct groups of comparable students, an age cohort and a mathematics course level cohort. A case study design with schools in three different sites (one urban, two suburban) was used. Three instruments were given: a Mathematics Level I Achievement Test from the Educational Testing Service, a 30-item Applications Test, and a 25-item Student Opinion Survey. At two of the sites, the UCSMP students outperformed both the age and course level cohorts by substantial amounts on both the achievement and application tests. At the third site, both comparison cohorts outperformed the UCSMP students on the achievement test, but results on the application test were mixed. At all three sites, there was little difference in the attitude items except on items concerning calculator use.

Student's enthusiasm and interest in learning mathematics are factors that influence learning outcomes. Where in the application of problem-based learning models on trigonometric material that aims to improve learning outcomes, but in the application process will also appear the activeness of students during the learning process takes place. This is intended to supplement the problem-based learning process in stages, including: understanding the problem, making a solution plan, implementing the plan, and reviewing the results obtained. From these stages there will also appear student activity and interest in the mathematics learning process which certainly contributes to learning outcomes. So the purpose of the study is to determine the effect of activeness and interest in student learning outcomes on trigonometry subjects through problem-based learning models. This research was designed using the One-Shot Case Study design. In this design there is only one group treated. The population in this study were all students of SMA Negeri 15 Semarang. With the sampling technique in this study using the Random sampling technique, obtained a sample of students in class X 7.

Humans can only try but God is the one who decides, when the government is full of optimism with economic growth which since 2016 – 2019 has been sharply corrected not in line with expectations, although many doubt it because it is too dreaming in the midst of the world's economic downturn and macro and micro indicators that are not supportive . At the end of 2019 the world was shocked by a humanitarian disaster, namely Covid-19 which started from Wuhan, China and spread throughout the world. Many observers say that Covid19 has spread to Indonesia but the government denies it and many ministers underestimate it and even make it a very unfunny joke.It was only on March 2, 2020 that the government announced that Covid19 had entered Indonesia. The government began to panic especially the people, people stormed shopping centers so that basic commodities became scarce even if they were available, the prices were very expensive, health products disappeared from the market because there were many inappropriate purchases and many people hoarded them in the hope of getting high profits. The government seems to be in a dilemma between the economy or the safety of its people, both of which are very important, especially since Indonesia's economic growth is largely influenced by public consumption.Now that we have entered the second year of Covid19, there are no signs that mean that covid19 will disappear in the world and especially in Indonesia on June 10-16, 2021, the surge affected by Covid19 is getting crazier, even as if it is out of control at the athlete's house in Jakarta, the occupancy is approaching 80%. has exceeded the limits set by the WHO, West Java, Central Java and East Java. The higher spike makes people more nervous and makes it more difficult to survive.
