Abstract

Students’ difficulty within learn geomety is closely related to the spatial ability. Spatial ability is needed by students to support and solve mathematics problems, partcularly in geometry. This descriptive qualitative research aimed to describe the spatial ability of the students JHS in manipulating and rotating mentally the object and also the ability imagine the shape of object from the different perspective by giving test of geometry three dimensions. The research subjects were 3 students of JHS with different mathematical ability, namely higher level, average level, and lower level. The research subjects were given test of geometry three dimensions I and interviewed. Time triangulation was conducted to check the credibility of the data by giving test of geometry three dimensions II and interviewed again. Based on the results of analysis were found that the ability to  change mentally the shape of object into different shape and the ability to move mentally the position of object were possesed by all of the subjects However, the higher and average level ability have difficulty in representing the image of three dimensions into two dimensions at the plane. Differ from those two subjects, the subject with lower level ability was found has difficulty in visualizing the shape of object from the different perspective.

Abstract

This study aims to develop Delphi XE8 software combined with Microsoft Access into a new application of the type of Setup Compiler called DASS. This application development uses 4-D development methods (Define, Design, Develop, and Disseminate). This application was developed based on Setup Compiler is an application with a small memory and easy in the process of deployment and is designed with two types of files Installer and Portable so easy in the distribution of files to users, especially students and lecturers. Validator gives an average response of 4.28 which means "valid". While on field trial average respondents give very good response with value 88.20%. The end result obtained 24 Delphi Form / GUI which has been developed with the use of Alpha Skins very interesting.
