Non-Euclidean geometry is an abstract subject and difficult to learn, but mandatory for students. The ethnomathematics approach as a learning approach to improve students’ spatial abilities. The aim of this research is to discover new elements of the spatial abilities of non-Euclidean geometry; determine the relationship between spatial abilities for Euclid, Lobachevsky, and Riemann geometry. This study used the micro genetic method with a 2×2 factorial experimental research design. The sample of this research is 100 students of mathematics education. There are three valid and reliable research instruments through expert trials and field trials. Data collection was carried out in two ways, namely tests and observations. Quantitative data were analyzed through ANCOVA, and observational data were analyzed through the percentage of implementation of the learning trajectory stages. The result is that the spatial ability of students who are given the ethnomathematics learning approach is higher than students who are given the conventional learning approach for Lobachevsky geometry material after controlling for the effect of Euclidean geometry spatial ability. Also, the same thing happened for the spatial abilities of Riemann geometry students. The learning trajectory is conveying learning objectives (learning objective); providing ethnomathematics-based visual problems; students do exploration; students make conclusions and summaries of exploration results; and ends with students sharing conclusions/summaries about concepts and principles in geometric systems. It was concluded that learning non-Euclid geometry through learning paths with an ethnomathematics approach had a positive impact on increasing students’ spatial abilities.

This article begins with a research collaboration between the Director of Seameo-Sen, based in Melaka Malaysia, and the Study Center in the Field of Learning for Students with Disabilities of FMIPA UNNES. The research objective to obtain the results of the analysis that revealed the use of the Multi-purpose Videos of Mathematical Teaching Aids to increase the absorption of students with special needs. The research method is with a qualitative approach. The subjects of this study taken one Malaysian Special School teacher, a Partner Researcher from Seameo-Sen, and the four of visually impaired and the mental retardation students at State Special School (SLBN) in Salatiga. Data analysis: data reduction, data presentation, data interpretation, and drawing conclusions, accompanied by class visit activities at SLBN Salatiga by applying Multi-purpose Videos of Mathematical Teaching Aids, interviews, Focus Group Discussion (FGD), and triangulation of data sources. As a result, by applying the Multi-purpose Videos of Mathematical Teaching Aids there was an increase in the absorption of SLB students. In conclusion, SLB needs to use Multi-purpose Videos of Mathematical Teaching Aids to increase the absorption of students with Special Needs in Mathematics.

Children with disabilities (CwD) have limitations in conceptual understanding of mathematics. Lack of numerical conceptual understanding will cause CwD to experience difficulty in counting. The purpose of this case study was to analyze the growth of numerical abilities of students with disabilities through the application of manipulative teaching aids. This research method used a qualitative approach. The subjects of this study were students of the seventh grade of the State Extraordinary School of Salatiga (SLBN) who had limited vision, mind, hearing, or speech impairment. After the results of the students' work were corrected, the qualitative data analysis was done by analyzing the results of the test, interview, and triangulation data. The results of this research: Through the use of Manipulative Teaching Aids, the numerical abilities of CwD could be improved and developed. It is recommended that teachers in ES should use Manipulative Teaching Aids so that the numerical abilities of CwD can be improved and developed.

Government and the private parties had also organized of Special School (SS) and Inclusive School. SS requires of math teachers who were professional in the material, but also master the needs of Children with Disabilities (CwD) in teaching-learning process. The problem: How to design the Teaching Aids for CwD through Extra-Curriculum Training (ECT) activities to Joyful Learning? The purposes of this research: (1) To find new ways how to grow the imaginative in mathematical thinking for students of Mathematics Education. (2) To find a Teaching Aids Design that suitable for CwD who studying in SS. (3) In order to create a Teaching Aids for CwD through activities based on ECT to Joyful Learning. The research method was done by qualitative approach. The research subjects were 6 students of Mathematics Education Study Program of FMIPA UNNES who were interested in attending of the training activities based on ECT. The results: (1) ECT can be a place to grow an Imaginative in Mathematical Thinking of students, (2) created the design of the teaching aids for CwD through activities based on ECT to Joyful Learning as a mirror of the imaginative growth in mathematical thinking for students.
