Problem Based Learning to Improve the Quality of Mathematics Teaching At Elementary School Education Academic Year 2018/2019 (Published)
Research conducted at the University of Quality Jl Ngumban Surbakti No 18 Medan, North Sumatera Indonesia. This study aims to determine the influence of problem based learning models to improve learning quality. The type of research that researchers use is a draft of the research on quasi exsperimen with research draft using Non-Equivalent Control Group Design experiments. The population in the study is all students of the second generation of PGSD with a total of 7 classes with a student number of 278 people and as a sample of the class 2B21 (X-2) as the experimental class as many as 40 people and class 2B22 (X-1) as control class as many 35 people are acquired in a random way. Research instrument is a form test of the 35 description of the problem that has been validated by the validator with the level of breliability of Cronbach’s alphadan of 0.83 very high category. Hypothesis testing conducted with Independent sample T-Test significantly ∝ = 5% and test requirement analysis is data normality and variance homogenization.Based on the results of the test Independent Sample Test obtained t = 6.2706 and t at the degree of freedom (DF = 73) and a significant level of α 0.05 is 1.6660. It was therefore null Hypotesis rejected and received an alternate hypothesis. Thus the implementation of a problem-based learning model is influential and can improve the outcomes of low-grade mathematics teaching the primary school teacher Education course of Quality University

The Effectiveness of Problem – Based learning Strategy in the Acquisition of Scientific Concepts in Physics and the Development of science operations among the Ninth Grade Female Students (Published)
The purpose of this study is to design the unit of the mechanics and its effect on substances among the ninth grade female students in Jordan depending on problem – based learning strategy. The study also aimed at identifying the problem – based learning strategy as well as highlighting the applied importance of physics in the students’ daily life in addition to specifying the effect of the problem – based learning strategy in the student’s acquisition of scientific concepts in physics and development of their science operation. The study produced a set of results and recommendations the most significant of which were that there is an effect of the problem based learning strategy in the ninth grade students’ acquisition of the scientific concepts in physics, and that there is an impact of the problem – based learning strategy in the development of science operations in physics among the ninth grade students. The researcher recommends to construct and design the units of the scientific subjects by means of modern learning strategies like the problem – based learning strategy to facilitate the learning process by male and female students
