“…Spatial orientation is one of the spatial abilities related to adaptability to spatial situations. Many studies on spatial ability have shown that spatial ability can improve and support students' mathematics performance (Cheng & Mix, 2014;Kospentaris et al, 2016;. VMK are an alternative media that can be used by elementary school students.…”

The purposes of the current study were to develop students' spatial orientation skills using Virtual Mathematics Kits (VMK) and to evaluate VMK as a form of digital media in terms of spatial orientation. This study involved 42 lower-class and 47 higher-class elementary school students as the intervention group and 36 lower-class and 41 higher-class students as the control group. The intervention group was administered spatial orientation activities for 10 weeks. These activities were performed using a VMK to facilitate solving spatial problems. In the end of activities, spatial orientation instruments administered to compare spatial orientation ability on each group. The findings of this study, spatial orientation activities using a VMK improved students' spatial orientation skills. More specific, VMK provides more significant effect on higher-class students. Finally, VMK allows students to explore many ideas and perspectives to solve various spatial problems. VMK can be used as a digital media that helps students to develop spatial reasoning.

“…According to [12] lecturers should give instructional activities that afford opportunities for fostering spatial abilities, and those should be included in pre-service programmes so that in the future they have a mathematical foundation to teach geometry. Then, based on [13] some researchers stated that educators need to develop instruction that emphasizes not the recall formal definitions and rules but construct dynamic activities of students for giving them visual spatial experiences and representations of geometrical shapes.…”

This research aims were to describe major difficulty for university students in solid geometry learning process and to know the causes of the problem. This research used qualitative method. The data was collected by testing and interviewing respondents. Respondents were 39 mathematics education students in class D, Universitas Muhammadiyah Surakarta, academic year of 2016/2017. The interview was conducted to 6 students who did most errors in major error category based on the test results. The result of this research showed that most of students had main difficulty to develop visual spatial skills in solid geometry learning. They could not visualize shapes of solid geometry objects well. It was because they did not understand well about steps for drawing intersection plane of cube, drew cube carelessly, did not know the shape of cube if the frontal plane was not standard, and remembered the answer of the exercise.

“…However, visualization tends to be associated with spatial aspects as a visual-spatial ability. Visual-spatial ability is the ability to understand the relationship between objects and space consisting of spatial visualization, mental rotation, spatial orientation, and perception (Bruce et al 2017;Haciomeroglu & LaVenia, 2017;Kospentaris et al 2016;Kotsopoulos et al 2017). Activities related to visual-spatial specifically encourage the formation of visual representations (e.g.…”

This research investigated types of multi-representations raised by prospective teachers in expressing algebra. This study used a qualitative approach with case study methods. As many as 112 prospective mathematics education teachers from Universitas Negeri Malang of Indonesia participated. Researchers used Algebra Task Sheet and Interview Guide Sheet as data collection tools. Then an analysis is carried out so that the following categories are obtained: subjects that symbolically express algebra, pictorial, and geometric. The results obtained showed that 74% of subjects expressed symbolically algebra, while 15% of subjects expressed pictorially, and 11% of subjects expressed geometrically. The research findings showed that there are three forms of representation raised by the subject in expressing algebra, namely the representation of algebraic symbols, image representations, and geometric representations. Most of the participants produced algebraic symbolic representations and some of them experienced obstacles in producing pictorial representations and geometric representations, also researcher found similar patterns in producing geometric representation namely, perception, appearance, strategy, and re-examination. Researchers recommend geometric representations for further research because they tend to be done by subjects with high mathematical abilities and rarely found research that produces geometrical representations when solving algebraic problems.
