Pembelajaran Kontekstual (Contextual Teaching And Learning) pada Bangun Ruang Sisi Datar di Sekolah Dasar

Mathematics learning should be more varied methods and strategies in order to optimize the potential of the student. Selection of methods, strategies, and approaches in designing the learning model in order to achieve an active and meaningful learning is a demand that must be met for teacher. Learning of mathematics which enables fun learning and is done naturally, so student can perform directly the things learned. It is appropriate with contextual teaching and learning is a concept that helps teacher relate the contents of the subject matter with the real world so that learning is more meaningful. In geometry content, teacher should be able to use contextual teaching and learning and also give an innovative questions that can improve higher order thinking skills of the students

Peningkatan Kemampuan Pemecahan Masalah Mahasiswa Pgsd Universitas Sarjanawiyata Tamansiswa melalui Problem Posing

This study aims to improve problem solving skills in Basic Mathematics courses through Problem Posing approach. This research is a Classroom Action Research. The subject of the research is the 2nd semester students of PGSD at Sarjanawiyata Tamansiswa University (UST). The research instruments are observation sheets, pretest and postest. Data analysis was done by descriptive statistc technique by determining mean, median, mode, lowest score, highest score, and completeness of study individually or classically presented in percentage form. The result of this research shows that Problem Posing approach can increase the problem solving ability of 2E PGSD students. This can be seen from the increase of the pra cycle stage which shows the problem solving ability of the students by 45 % has increase in the first cycle of 52,72 % and the second cycle there is also a significant increase of 84 %. This means that the implementation of class action research is successful. Based on the result of the research, the implications that can be given, among others, is this study provides an overview of the improvement of student problem solving skills after applying the problem posing approach. This learning provides students the opportunity to learn independently and improve their creativity

Implementasi Pembelajaran Origamasains untuk Menumbuhkan Kecintaan terhadap Matematika dan Sains Sejak Dini

This study aims to provide an overview of how the learning using origamasains can emerge fondness to mathematics and science subjects from the early age. The result of the study was expected to become the input for the upcoming learning and the reference for developing the learning at the basic level especially for the mathematics and science subjects. In order to get the accurate research result, the qualitative research method was employed. The data were analyzed using the data collection, data reduction, data presentation, and data validity check procedures. The research was conducted in May - September 2018 at Jageran Yogyakarta early childhood school. The primary data being analyzed were the impression of the students to the given learning and the results of the interviews to the students. The finding showed that the students could learn better using the origamasains learning. In this first activity,80% of the students showed fondness to the given learning activity, while 20% of the students expressed normal impressions and 0% of the students showed dislike. In this second activity 100% of the students showed fondness to the given learning activity. Meanwhile in the third activity, 75% of the students showed fondness to the given learning activity, 20% of the students expressed normal impressions and 0% of the students showed dislike. In that third activity, the classroom’s good atmosphere was destructed by the crying from some students.   References Cossentino, J. (2005).

Phenomenologi Study: Risk Factors Related to Fall Incidence in Hospitalized Pediatric Patient with Theory Faye G. Abdellah

The incidence of the fell is one of the hospital serious problems, especially in the hospitalized patient. The number of fall incidence is one of the main indicators in patient safety and hospital quality. Qualitative study with phenomenology approach was conducted to explore factors affecting the risk of fall in pediatric patients. Four nurses consist of two team leaders and two associate nurses participated in in-depth interviews. The findings from the interviews were triangulated in some process including an interview with the head of an inpatient installation, supervisor, and patient family, participative observation, documentation of form Humpty Dumpty and operational standard prevent the risk of fall. The result data was analyzed with the content analysis method and concluded with a fish bone. Four themes emerged from the analysis: knowledge, human resources, environment, and facilitation. Bad implementation of operational standard procedure, heavy workload of a nurse with unbalance ratio between patient and nurses, the slippery floor, unfixed bedside rails, and unavailability of patient bell have a role in affecting the risk of fall. This study suggests to held fall prevention education, make a review of nurse's workload with recalculate the ratio of patient and nurse and upgrade the hospital facilitation and environment situation

This research was conducted in one of the elementary schools in the Wates, Kulon Progo area. This study aims to develop learning media based on snakes and ladders mathematics Augmented Reality for fifth grade students and describes the feasibility of mathematics-based snakes and ladders learning media Augmented Reality for fifth grade students. This development research uses the ADDIE development research model which is modified into three steps, namely Analysis, Design and Development. The methods used are qualitative methods and quantitative methods. The results showed that the learning media for snakes and ladders is mathematics based Augmented Reality meets the eligibility criteria as evidenced by the validation results of media experts getting an average score percentage of 99.57% with the "Very Eligible" criteria, the material expert validation results get an average score percentage of 94.29% with the "Very Eligible" criteria and the results of the questionnaire the media trial obtained an average score of student responses as a whole, namely 96.54% with the "Very Good" criterion. Then, the results of observations and interviews showed that teachers and students gave a positive response to the mathematics-based snakes and ladders media Augmented Reality. Thus, learning media based on snakes and ladders mathematics Augmented Reality can be used as an alternative learning media in class V elementary school

Optimization of Mathematics Learning with Problem Based Learning and 3N (Niteni, Nirokke, Nambahi) to improve mathematical problem solving skills

Learning mathematics is considered a difficult subject for students. Learning difficulties experienced by students often have an impact on the lack of awareness of the importance of mathematics in students' daily life. Optimization of learning mathematics with problem-based learning can be applied using the 3N teachings of Tamansiswa concepts, namely Niteni, Nirokke, Nambahi. This research is qualitative in the form of a literature review. This article describes how teachers can optimize PBL with Tamansiswa teachings in learning mathematics so that students become enjoy, more effortless, and responsive in applying mathematical concepts in daily life
