Developing Students' Ability of Mathematical Connection Through Using Outdoor Mathematics Learning

The Purpose of this study is to determine the achievement and improvement of students' mathematical connectionability through using outdoor mathematics learning. 64 students from the fifth grade of Primary School at SDN 65 and SDN 67 Bengkulu City were taken as the sample of this study. While the method of the research used in this research is experiment with quasi-experimental designs non-equivalent control group. The results of the study are as follows: (1) There is an increasing ability found in mathematical connection of students whom taught by using outdoors mathematics learning is 0,53; (2) Based on statical computation that achievement of students' ability of mathematical connection is taught by using outdoor mathematics learning score is 71,25. It is higher than the students score 66,25 which were taught by using the conventional learning. So as to improve students' mathematical connection, teachers are suggested to use the outdoors mathematics learnin

The effect of the use of indigenous knowledge-based physics comics of android-based marbles games on verbal representation and critical thinking abilities in physics teaching

This research aims to reveal the effectiveness of the use of an indigenous knowledge-based physics comic of Android-based marbles games on verbal representation and critical thinking abilities. It is a quasi-experiment applying the pretest-posttest control group design. The research sample consists of two classes: the control and experimental classes, each of which consists of 35 students established using the cluster random sampling technique. The effectiveness of the indigenous knowledge-based physics comic of marbles games was analyzed using the quantitative method applying the effect size analysis. The result of the effect size analysis obtained from Cohen’s f in verbal representation ability is 0.11 interpreted as medium effect size and critical thinking ability is 0.43 interpreted as large effect size. This shows that the developed indigenous knowledge-based physics comic of Android-based marbles games in physics teaching gives effects to verbal representation and critical thinking abilities of the students. In other words, the developed comic is effective in improving verbal representation and critical thinking abilitiesPeer Reviewe

Effect of Game-Based Learning in Vehicle Air-Conditioning Course on Cognitive and Affective Skills of Vocational Students

Refrigerant and air conditioning course in vocational college is challenging to students and teachers as indicated by the unsatisfactory student’s examination results. Students come diverse backgrounds with poor basic skills and low motivation which, is difficult to address using the traditional interactive teaching and learning methods as currently practiced by teachers Therefore, game-based learning is suggested as an alternative to increase students’ motivation and achievement. A study was conducted to assess the effect of game-based learning on learning of the cognitive (recall the fact, concept, and procedure) and affective (respond/reaction) skills of vocational students in automotive air-conditioning course.  A quasi-experiment was conducted on 30 students from two vocational colleges who were randomly assigned to the experimental and control group. The experimental group underwent a game-based learning method and tested using pre-test, post-test, and questionnaire. Whereas the control group underwent the existing method and tested using only pre-test and post-test. The teaching and learning module were developed based on the ADDIE model. The module has been analysed for usability and method. The results of this experiment show that the achievement of the experimental group is better than the control group. The students show good responses and reactions towards game-based learning. In conclusion, game-based learning is effective for student’s cognitive and affective skills in this course

Analytic Framework for Students' Use of Mathematics in Upper-Division Physics

Many students in upper-division physics courses struggle with the mathematically sophisticated tools and techniques that are required for advanced physics content. We have developed an analytical framework to assist instructors and researchers in characterizing students' difficulties with specific mathematical tools when solving the long and complex problems that are characteristic of upper-division. In this paper, we present this framework, including its motivation and development. We also describe an application of the framework to investigations of student difficulties with direct integration in electricity and magnetism (i.e., Coulomb's Law) and approximation methods in classical mechanics (i.e., Taylor series). These investigations provide examples of the types of difficulties encountered by advanced physics students, as well as the utility of the framework for both researchers and instructors.Comment: 17 pages, 4 figures, 3 tables, in Phys.

Learning Application Derivative Algebraic Functions: Ethnomathematical Studies and Digital Creator Books

Learning mathematics has been meaningful if it is associated with real-life problems. Ethnomathematics is an activity in which mathematical concepts are related to the local "Lontong Sayur" culture that students often encounter in real life. Ethnomathematics needs to be applied to students at the high school level. It aims to make it easier for students to understand mathematical concepts, one of which is ethnomathematics based on Digital Book Creator. This study aims to create a product as a Book Creator based on the application of ethnomathematics in learning. Applications derived from algebra help teachers create conducive conditions for students to learn. The development model used in this research is the Borg and Gall development model in the research and data collection stages. Book Creator is a simple tool for creating exciting books. The validation of materials, learning media, and culture received a score of 3.58 using "good" criteria. Book Creator can be developed to understand documents more in context to understand documents from concrete to abstract and provides several menus, namely: a) Presenting user guides and brief descriptions of Book Creator; b) Business plans and concept maps; c) A summary of the material is presented in stages equipped with sample questions and quizzes containing learning videos, audiovisual sections, and aptitude tests; and d) Summarizing, presenting summary/basic learning materials
