Developing modified indonesian children song lyrics to teach vocabulary to elementary school third graders

Abstract: Lagu merupakan salah satu alat edukasi yang membantu penguasaan bahasa peserta didik. Lagu menyediakan media yang menarik dan instruksional pada pembelajaran. Ini menarik karena siswa akan lebih menikmati pembelajaran. Atmosfer yang mendukung dari lagu telah membuktikan bahwa lagu merupakan media yang sangat kondusif dan efisien. Kebanyakan siswa sekolah dasar tidak dapat mengingat kosakata dengan membaca buku atau mengulang guru. Mereka akan merasa bosan dan tidak memperhatikan karena materi tidak menarik. Guru sSekolah Dasar yang menggunakan lagu sangat membantu siswa untuk meraih full mental, potensi intelektual, dan kreatif. Karena siswa belajar melalui pengulangan dan akitifitas multi sensorik, lagu sangat membantu dalam mengingat konsep bahasa mulai speech sampai kecakapan mendengarkan dan berbicara. Dengan menggunakan lirik lagu, diharapkan guru dapat memotivasi siswa buntuk belajar dan memperhatikan materi yang guru sampaikan. Songs become one of the most valuable educational tools that aid the language acquisition as well as the whole learner’s physical and mental development. Song can provide attractive and instructional media in learning activities. It is attractive because the children will have more fun in learning processes. The pleasant, relaxed atmosphere fostered by songs has proven to be highly conducive to efficient learning. Most of students in elementary school are unable to memories vocabulary easily by read the textbook or by repeating the teacher. They feel bored and do not attention because the material which is presented by the teacher is not interesting and attractive. Elementary educators who add songs to the language arts classroom help students achieve their full mental, intellectual and creative potential. Because children learn best through repetition and multi-sensory activities that engage the full body, singing familiar songs and doing activities set to music help kids memorize and retain language arts concepts from parts of speech to proper listening and speaking skills. By using songs lyric during the teaching learning process, it is hoped that the teacher will be able to motivate the students to learn and pay attention to the material the teacher presents.

The Effect of Sodium Hydroxide Molarity on Strength Development of Non-Cement Class C Fly Ash Geopolymer Mortar

Abstract: The use of fly ash as cement replacement material can overcome the environmental issues, especially the global warming problem caused by the greenhouse effect. This is attributed to the CO2 gas produced during the cement manufacturing process, which 1 ton of cement is equivalent to 1 ton CO2. However, the major problem of fly ash is the requirement of activators to activate the polymer reactions. The most common activator used in non-cement or geopolymer material is the combination of sodium hydroxide (NaOH) and sodium silicate. This study aims to identify the effect of NaOH molarity as activator on strength development of non-cement class C fly ash geopolymer mortar. The molarity variations of NaOH were 6 Molar (M), 8M, 10M, 12M, 14M and 15M. The compressive strength test was performed at the age of 3, 7 and 28 days in accordance with ASTM standard, and the specimens were cured at room temperature. The results show that the highest compressive strength was achieved by geopolymer mortar with a molarity of 12M. It exhibits a higher strength to that normal mortar at 28 days. However, the use of NaOH molarity more than 12M tends to decrease the strength of non-cement geopolymer mortar specimens.

Pengembangan Media Pembelajaran Berbasis Android pada Materi Gerak Parabola Untuk Siswa SMA

Abstract: The development of science and technology encourages various reform efforts in the learning process. Meanwhile, teachers are required to be able to utilize information and communication technology for self-development. Android is one of the most popular operating systems today. The purpose of this research is to make android instructional media that has the appropriate characteristics so that it is suitable for high school students. The development of this medium follows the Borg and Gall groove that has been simplified by the Center for Policy Research and Innovation consisting of 4 stages of needs analysis, initial design, validation and revision, small-scale and revised trials. In the development study, the learning medium has been validated by an expert validator with 77.53% results or is eligible to use. Trial program conducted by students at 2nd Muhammadiyah Senior High School at Magelang city with a result of 68.82% or eligible to use. Research data collection method used is observations, questionnaires and documentation. Based on data analysis then in this study can be concluded android learning media on parabolic motion material can be used as alternative learning resources with offline characteristics, practice questions and android operating system specifications minimum 5.0.

The Effect of Constructivist Learning Using Scientific Approach on Mathematical Power and Conceptual Understanding of Students Grade IV

Abstract: This study used a model of Concurrent Embedded with the aim of: (1) determine the difference between the conceptual understanding and mathematical power of students grade fourth who take the constructivist learning using scientific approach and direct learning, (2) determine the interaction between learning approaches and initial competence on the mathematical power and conceptual of understanding, and (3) describe the mathematical power of students grade fourth. This research was conducted in the fourth grade elementary school early 2015. Data initial competence and mathematical power obtained through tests, and analyzed using statistical tests multivariate and univariate. Statistical analysis of the results showed that: (1) There are differences in the concept of understanding and mathematical power among the students who follow the scientifically-based constructivist learning than students who take the Direct Learning in terms of students initial competency (F = 5.550; p = 0.007 < 0.05), and (2) There is an interaction between the scientific-based constructivist learning approach with an initial competence (high and low) on the ability of concept of understanding and mathematical power (F = 5.259; p =0.033 < 0,05). Observations and in-depth interviews with students, shows that the construction of mathematical power of students have influenced the thinking of students in problem solving and contributes tremendous increase students' math skills. Researcher suggested that the learning of mathematics in schools using scientifically- based constructivist approach to improve the mathematical power of students and conceptual understanding.
