Abstract

The influence of the advances of science produces technological innovations that leverage on education, economics, social and self-development. In education, design of laboratory experimental modeling tools continues to be carried out by researchers to improve learning effectiveness. Wheel movement experiments related to belts include one of physic learning activities. The parameter measured from the creation of modeling tool is the wheel speed and analysis of wheel motion related to the belt. The system can be controlled in speed and time using Blynk application. Video recordings are used as circular motion analysis material on Tracker applications. The design of system is a box size 35 cm in length, 20 cm in width and 18 in height consisting of one switch, LCD, and two wheels connected by a belt. Wheel 1 has a diameter of 15 cm and wheel 2 is 10 cm. Based on data analysis, the results of physical parameters were obtained with high accuracy and precision values using standard measuring instruments, namely tachometers, calculation of the theoretical formula. The system's precision was 98.84% and speed accuracy for 30 rpm, 50 rpm and 80 rpm were 99.3%, 99.19% and 99.93%. Frequency values increased according to the increase in input speed and compared to the reverse period.  The angle speed will increase as the wheel spokes become smaller. So, the wheel modeling tool related to the belt using speed and time control with the Blynk application as well as the Tracker video alysis can work effectively and validly.

Abstract

The purpose of the this research was to know the effect of the use of Contextual Teaching and Learning (CTL) learning models on the learning outcomes of addition and subtraction of fractions in class V SD. This research design is quasi experiment with nonequivalent control group design. The sample in this study is class V SDN 05 Tarok Dipo as a Conventional class and SDN 16 Tarok Dipo as a class CTL. The results showed that there were differences in students' mathematics learning outcomes using Conventional models with the CTL Guguk Panjang Cluster IV model in Bukittinggi City. This is evidenced by the results of tcount 1,96 and t table at a significance level of 0,05 at 1,68595, so that t count> t table.
