Wedges: Stories as Simple Machines

This piece of comics-based research (CBR) details the use of arts-based methods in ongoing research with young transgender or otherwise gender diverse children. Drawing from both the anthropology of childhood and draw–write–tell research in public health, the central innovation of this methodology hinges on gathering children’s narratives in a less coercive manner that holds their stories intact and produces better, more trustworthy research. Discussion includes problematizing and problem-solving contemporary “child friendly” methodology, exploring the role of the child informant in qualitative research, and illustrating how arts methods can inform deeper understanding of participant data when applied in a systematic format.

How to Improve Students’ Cognitive Ability?: The Influence of Two Stay Two Stray Type Cooperative Model Assisted by Innovative Module

This study aims to see the effect of using the two stay two stray learning model assisted by an innovative module on the cognitive learning outcomes of students on the topic of simple machines. This quantitative study used a quasi-experimental design with a pretest-posttest control group design. This study consisted of 2 classes, class VIII A as the experimental class and class VIII B as the control class. The results showed that the average of the cognitive test of the experimental class was 80.00 and the control class was 72.67. The results of data processing using the Mann Whitney test with a sig level of 0.05 revealed that the results of sig.2 tailed were 0.000, less than 0.05, which means that there is a difference in the posttest average value of students’ cognitive learning outcomes in the control and experimental classes.

Penerapan Metode Eksperimen untuk Meningkatkan Hasil Belajar Siswa Pada Materi Pesawat Sederhana Kelas V SD

<em>The problem of this research is the students' learning outcomes in the science subject of simple aircraft for class V SD Negeri Citepus 01 in the 2015/2016 academic year. The purpose of this study is to improve student learning outcomes. This research was conducted in 2 cycles consisting of planning, implementation, observation and reflection. The subjects of this study were the fifth grade students of SD Negeri Citepus 01, totaling 35 students. The technique of collecting the results of the short and descriptive test results. Data analysis was carried out by analyzing quantitatively and qualitatively, to find out whether or not student learning was complete or not. Based on the learning outcomes from the pre-cycle, cycle I and cycle II experienced a significant increase. In the pre-cycle learning outcomes were 43% and increased in the first cycle by 69%, while the second cycle increased even more, namely learning outcomes reached 91%. The conclusion of this study is that the application of the experimental method can improve the learning outcomes of fifth graders at SDN Citepus 01 in science subjects about simple machines</em>

PENGEMBANGAN MODUL IPA BERBASIS INQUIRY LESSON PADA MATERI USAHA DAN PESAWAT SEDERHANA UNTUK MENINGKATKAN KREATIVITAS ILMIAH SISWA

THE DEVELOPMENT OF INQUIRY LESSON-BASED SCIENCE MODULE IN WORK AND SIMPLE MACHINE MATERIAL TO IMPROVE STUDENTS’ SCIENTIFIC CREATIVITY AbstractThis research aimed to: 1) develop inquiry lesson-based science modules to improve student’s scientific creativity, 2) determine the feasibility of an inquiry lesson-based science module and 3) find out the effectiveness of inquiry lesson-based science modules to improve students’ scientific creativity. The science module material developed is work and simple machines. The module learning steps are arranged according to the inquiry lesson syntax and students’ scientific creativity indicators. The type of research is research and development (RnD) used Borg and Gall procedure that modified into 9 stages: 1) research and information collection, 2) planning, 3) initial product development, 4) initial field trial, 5) initial product revisions, 6) small-scale trial, 7) second product revisions, 8) operational field trial and 9) final product revisions. Characteristics of the module analyzed using descriptive analysis, module feasibility analyzed based on criteria scores and the module effectiveness analyzed using N-gain score. The result showed that: 1) inquiry lesson-based module has been successfully developed with characteristics according to the inquiry lesson models to improve students’ scientific creativity, 2) inquiry lesson-based module was very feasible used in learning process, 3) inquiry lesson-based module was effective in improving students’ scientific creativity with N-gain score of 0,55.AbstrakPenelitian ini bertujuan untuk: 1) mengembangkan modul IPA berbasis inquiry lesson untuk meningkatkan kreativitas ilmiah siswa, 2) mengetahui kelayakan modul IPA berbasis inquiry lesson, 3) mengetahui keefektifan modul IPA berbasis inquiry lesson untuk meningkatkan kreativitas ilmiah siswa.

Energy Production and Conversion

In many ways, energy production and its conversion from one form to another is the heart of mechanical engineering. The history of energy is vast, beginning with efforts to make the energy produced by human muscle more effective through the use of lubricants or the application of the so-called six simple machines in pre-history. By the end of Classical antiquity, inventors and engineers had harnessed the power of wind to move ships and water to grind flour. In the eighteenth century the first practical heat engines opened the era of fossil fuels, utilizing the expansive power of steam to convert thermal energy to mechanical energy.
