Exploring computer assisted learning for low achieving children: A comparative analysis study

Learning assistance or support is essential for a learner regardless of their cognitive ability and learning preference. Computer assisted learning (CAL) is one of the facilitation that widely explored as alternative learning assistances with different concepts, approaches, contents and target users. The main concern of this study is to explore and identify learning concepts and approaches that have been employed in previous research for normal and learning disabilities learners. In relation with the intention, 15 articles from past five years (2010-2015) are selected for review and analysis processes in this comparative analysis study.The finding shows some similarities and differences of CAL concept and approach for both type of learners. Some insights and suggestions are drawn based on the extracted concepts and approaches specifically for low achieving children as their learning assistance in primary school

Keefektifan Model Pembelajaran Problem Solving Berbantuan Video Interaktif Terhadap Kemampuan Pemecahan Masalah Siswa Kelas III SDN Gedawang 01 Semarang

The purpose of this study is to determine the effectiveness of the problem solving learning model on the problem-solving ability of grade III students of SDN Gedawang 01 Semarang. This type of research is quantitative research with a problem solving learning model using interactive videos. The population in this study was grade III SDN Gedawang 01 and grade III SDN Gedawang 02 Semarang totaled 56 students. Meanwhile, the sample, namely class III SDN Gedawang 01, was 28 students. Data collection techniques in the form of observations, questionnaires, interviews and tests. The technical data analysis used is the Independent Test sample T-test and the Simple Linear Regression Test. The results showed that: there was a difference in the average problem solving ability of students between the control class and the experimental class, which can be seen from 1) Independent Test T-test sample and obtained thitung > ttabel (3.83 > 2.13) with a sig value. (2 -tailed) i.e. 0.001<0.05 then Ho is rejected and Ha is accepted. 2) There is an effectiveness of interactive video-assisted problem solving learning models, which can be seen from the Simple Linear Regression Test and obtained a signification level of F 67.195, sig:0.000a < 0.05. So it can be concluded that the interactive video-assisted problem solving learning model is effectively used to improve the problem-solving ability of grade III students of SDN Gedawang 01 Semarang

KEMAMPUAN PEMECAHAN MASALAH MATEMATIKA SISWA KELAS V SEKOLAH DASAR DALAM MENYELESAIKAN SOAL LEVEL C4 TENTANG MATERI DEBIT

The purpose of this study is to describe the mathematical problem solving abilities of fifth grade elementary school students in solving c4 level questions about discharge or volumetric flow rate material from various levels of ability. This research is motivated by the low ability of students to solve mathematical problems in solving C4 level problems. The subjects of this study were six students of class V-B at SDN 013 Pasir Kaliki. The research method used is descriptive qualitative research that describes the mathematical problem solving abilities of fifth grade students who have high, medium, and low level abilities in solving C4 level problems according to the way they are, without manipulation during research. Based on research according to George Póly, this study shows the results that students who have high-level mathematical problem solving skills can go through four steps of problem solving. Students who have medium level mathematical problem solving skills are mostly able to go through 3 steps of problem solving and only understand the concept of discharge material, beyond the subject's volume, timing, and discharge's subject. So it is less able to think deeply to solve the problem. Students who have low level mathematical problem solving skills are only able to go through the stage of understanding the problem. The implications for further learning, students with high level abilities are given enrichment, students with moderate level abilities are given remedial, and students with low level abilities are given repetition of material by applying the information processing model. Key word: problems solving and C4 level mathematical questions

PROSES PEMECAHAN MASALAH MATEMATKA SISWA BERKEMAMPUAN TINGGI BERDASARKAN LANGKAH POLYA

The purpose of this study is to determine the process of solving the problem of students who are high-ability based on Polya step. This research uses the qualitative approach. The subject in this study was a high-ability student. The results of this study indicate that the ability to solve the problem of high-ability students based on Polya steps are: (1) Understanding the problem begins by understanding the vocabulary, identifying all the facts in the form of existing information data, connecting all information from the identification result, and ending by identifying the question ; (2) A plan for splitting begins with the selection of operations and establishes the formulation of equations; (3) Implement the plan of splitting; (4) Re-checking of the settlement result obtained by substituting the result obtained to the initial equation

KESALAHAN KONSTRUKSI KONSEP MATEMATIS DALAM PROSES REPRESENTASI VISUAL MAHASISWA

Belajar matematika merupakan proses konstruksi pengetahuan dengan cara mengaitkan suatu konsep matematika dengan konsep matematika yang lain. Penelitian ini dilakukan untuk mendeskripsikan kesalahan konstruksi konsep matematis dalam proses representasi visual terkait menggambar grafik fungsi sebagai dasar menentukan luas  daerah di bawah kurva. Jenis penelitian yang digunakan adalah kualitatif dengan pendekatan deskriptiif. Subjek penelitian adalah tiga mahasiswa S1 program studi Pendidikan Matematika Universitas Muhammadiyah Malang. Pengumpulan data dilakukan dengan memberikan soal tes dan melakukan wawancara. Hasil pekerjaan mahasiswa tersebut diambil tiga data berdasarkan kesalahan tertinggi untuk di identifikasi kesalahannya kemudian dianalisis lebih lanjut dengan mengaitkan hasil wawancara berdasarkan konsep matematis dalam merepresentasikan grafik. Hasil penelitian menunjukkan bahwa kesalahan konstruksi konsep matematis dalam proses representasi visual mahasiswa adalah pseudo construction ”salah”, lubang konstruksi, mis-analogical construction dan mis-logical construction. Kesalahan tersebut terjadi karena mahasiswa hanya terpaku pada rumus, tidak memeriksa ulang setelah menggambar grafik dan kurang memahami konsep, baik konsep materi prasyarat atau materi pokok
