The purpose of this research was to determine the effect of learning models to studentachievement. Learning models compared between NHT-CTL, NHT and direct instruction.Method of research used quasi experimental with the factorial design of 3x1. Populationof this research was all students class VIII in SMP Negeri at Madiun City. The samplingtechnique using a stratified cluster random sampling. Samples in this research were 266students with 91 students as experimental class I, 88 students as experimental class II and87 students as control class. Data collection methods used documentation andtest.Hypothesis testing was performed using one-way analysis of variance with unequalcells. Based on the results of hypothesis testwere concluded that NHT-CTL learningmodel gave better achievement than NHT learning model and direct instruction, whileNHT learning model and direct instruction gave the same achievement. Keywords: NHTlearning model, CTL approaches, learning achievement

The digital era makes education begin to be contaminated with technology. This study aim to determine the effectiveness of Virtual Mathematics Kits (VMK) viewing by student' mathematical literacy. The VMK was used in extracurricular activities based on mathematical literacy. 83 elementary school students (grade 5) in 4 school participated in this study. There were two intervention classes and two non-intervention classes. All classes were given mathematical literacy activities for 6-weeks period (90-min each week). The VMK used in intervention classes. The activities focus on student' ability to make ideas, reasoning and solve various mathematical problem. The mathematical literacy activities led to improvements in both of two classes. However, the use of VMK make student' mathematical literacy much better. The VMK support student to reason and manipulated mathematical object although students have difficulty to operate VMK. This study showing the use of digital media (VMK) support student' mathematical literacy.

This purpose of the research was to determine the effectiveness of learning start with a questionmethods on geometry learning. The effectiveness of these methods would be compared withpresentation method. The method of this research was quasi experimental method with 2x1factorial design. The population in this study was the third semester students at PGSD IKIPPGRI MADIUN while the sample was 3G as an experimental class and 3C as the control class.The sampling technique used was cluster random sampling. Methods of data collection in thisstudy was test method and divided into two: pre-test and post-test. Data analysis techniquesused in this study is a t-test with two independent samples. The results of this study were learningstarts with a question method was more effective than presentation method.

Computational thinking is needed in the 21st century, where we live in an era of digitalization. Also, there is a global movement to incorporate computational thinking into the education curriculum, especially Mathematics education. The different of this research with others is this research compares the Polya problem solving and computational thinking. This research was conducted to find out how the relationship/relationship of the Polya problem-solving with the steps of computational thinking. The method used in this research is descriptive qualitative. The subject of this study was mathematics education students. The results showed that the relationship between problem-solving and computational thinking of respondent when solving the problem is when defining the problem in the context of problem-solving, the respondent performs the stage of decomposition and abstraction in the context of computational thinking. During the planning process of the solution process, respondents carried out the generalization stage. When the scene is carrying out the plan and the problem solver to look back to evaluate the solution, the respondent performs the debugging and algorithmic steps.

The field of spatial reasoning has seen a lot of research. The process of spatial reasoning, on the other hand, needs to be investigated further. The goal of this study is to capture an elementary school student's spatial reasoning process when solving geometric problems. The spatial skills used in solving geometric problems were also identified in this study. A geometric test was given to seventeen elementary school students. Three participants were chosen as the study's subjects based on their written responses. According to the findings, the subject's spatial reasoning process always begins with the processing of information in mental visualization. Mental visualization is used to help with orientation and selecting the appropriate visual perspective. The spatial skills of spatial visualization and spatial orientation are critical in spatial reasoning. Furthermore, this research initiated the emphasis on the focus of spatial reasoning in the process.

Penalaran spasial abstrak merupakan penalaran terkuat dari siswa autis. Dalam penelitian ini kami ingin mengidentifikasi penalaran spasial siswa autis berdasarkan kategori penalaran spasial (visualisasi spasial, rotasi mental, dan orientasi spasial) dan level penalaran (abstrak dan kongkrit). Sebanyak 46 siswa autis dan 46 siswa non-autis berpartisipasi sebagai subjek. Semua subjek diberikan 6 tipe tes penalaran spasial yang meliputi ketiga kategori serta level penalaran spasial. Hasil yang diperoleh yaitu siswa autis memiliki keunggulan pada kategori visualisasi spasial abstrak sementara siswa non-autis memiliki keunggulan pada kategori visualisasi spasial kongkrit. Hasil tersebut menunjukkan secara spesifik bahwa visualisasi spasial abstrak merupakan penalaran spasial terkuat yang dimiliki oleh siswa autis. Dengan demikian penelitian ini memberikan gambaran baru mengenai kemampuan penalaran spasial siswa ditinjau dari kategori penalaran serta level penalaran.
