Pengembangan Model Elaborasi untuk Membangun Konsep Sistem Pencernaan pada Manusia melalui Multimedia Kelas XI

Penelitian ini dilatarbelakangi dengan pembelajaran Biologi di kelas XI IPA di SMA Negeri 1 Batu Ampar masih dilaksanakan secara konvensional, pebelajar diharuskan menghafal konsep-konsep yang tidak tahu penerapannya. Sehingga, mata pelajaran Biologi menjadi sesuatu yang tidak disukai pebelajar, atau bahkan mereka menganggapnya sebagai mata pelajaran yang abstrak dan rumit. Tujuan dari penelitian ini adalah tersedianya sumber belajar menggunakan pengembangan model elaborasi untuk membangun konsep sistem pencernaan pada manusia melalui multimedia. Penelitian dilakukan dengan pengembangan produk (Research and Development) dengan pendekatan kualitatif naturalistik, dan data yang diolah dengan analisis data kualitatif, serta pengambilan sampel dengan snowball sampilng. Perilaku belajar para pebelajar yang menggunakan model elaborasi melalui multimedia berupa perolehan belajar membangun konsep sistem pencernaan pada manusia selama kegiatan uji coba lapangan berdasarkan hasil rekaman dan foto menunjukkan bahwa pebelajar merasa senang dan aktif, serta merasa mudah dalam menemukan konsep, sehingga pebelajar mampu membangun konsep sistem pencernaan pada manusia secara mandiri. Kata Kunci : Model Elaborasi, Multimedia, Konsep Sistem Pencernaan Pada Manusia. Abstract: This research is motivated by the learning of Biology in class XI IPA at SMAN 1 Batu Ampar was carried out conventionally, learners are required to memorize concepts that do not know the application. Thus, the subjects Biology into something undesirable learners, or even they consider it as a subject of abstract and complex. The general aim of this research is to produce the learning resources that using the development model for constructing concept of human digestive system through multimedia.The study was conducted with product development (Research and Development) with naturalistic qualitative approach, and data that is processed with the analysis of qualitative data, as well as snowball sampling with sampilng. Conduct study of the learners who use the model elaboration through multimedia to build the concept of the human digestion system during activity field trials based on the recordings and photographs indicate that learners are very active in following the learning steps which have been designed in multimedia and more motivated, eliminate boredom, exciting, and fun at the self-learners. Keywords : Models Elaboration, Multimedia, Concept Of The Human Digestive System

This study aims to explore how an increase in the representation and understanding of the mathematical ability of students after learning the treatment given by problem-based learning model and conventional, the association between the representation and understanding of mathematical abilities of students as well as student activity during the learning takes place. This research is an experimental study in SMP Negeri 1 Sungai Kunyit school year 2014/2015. Pretest and posttest study design is given in the experimental group and the control group. The experimental group learning through problem-based learning model and the control group learned through conventional learning. Based on the final test analysis results obtained representation and understanding of mathematical ability of students increased scores after being given pretest and posttest, besides students learn problem-based learning model is significantly there is a difference compared with students who studied with conventional learning. There is an association (the relationship) between mathematical ability and understanding repesentasi. While the activity of students in problem-based learning model and students showed increased active during the learning activity

Implementasi Model Pembelajaran Berbasis Masalah pada Materi Luas Permukaan Prisma dan Limas di SMP

This research purposed is for knowing the learning efectifity using problem based learning model based on prism surface area and pyramid in SMP Negeri 3 Sungai Raya. The research method that being used is descriptive research. The research from is pre-experimental with the design the one case study or post-test only design. The sample was 36 students. The result of data analysis showing us that the completeness of student result classical is not reached, the category of student activity is quite active, the student give a positive respons, syntax (step) learning is done with good category. In conclusion learning is using problem based learning is not effective to be applied on learning prism surface area and pyramid in SMP Negeri 3 Sungai Raya grade VIII B class

Pemanfaatan Media Kit dalam Proses Pembelajaran Matematika di SMP Negeri Kota Pontianak

This study focused on the use of the media kit in learning mathematic at junior High School in Pontianak City. The kinds of kit considered in usefulness, preparation, take care of activity and the storage kit media. The result of study showed that use has been carried out by teachers at school but the utility was not optimal. The teacher has prepared the times, the number of media, study materials and the safety but less of focus on students characteristic and the teachers ability. The implementation is focus only on basic competency on space shape and flat space shape but another competency was not use the available of kit. The teacher competence is more increase in usefulness of kit. The storage of kit is get more pay attention in order the kit storage is more tidy and take care well. The support of principal and advisor need to be done to give motivation to the teacher in utility mathematic of kit media at school
