Abstract: This advanced research aims to determine the feasibility, effectiveness and practicality of mobile math products in geometry courses an expanded manner in LPTKs in Central Java. This research method uses the Borg and Gall development Model with 10 stages that’s are; research and information collecting, planning, develop preliminary form of product, preliminary field testing, main product revision, main field testing, operational product revision, operational field testing, final product revision, dissemination and implementation. In this follow-up study using steps 7-10 with the produced mobile math products have been tested expanded. The mobile math products obtained from students and lecturers responses with the average percentage of student responses, namely the media aspect by 90%, material aspects by 90%, language and display aspects by 86% and examples of questions and exercises by 93%, its means that students generally, assess this product as valid and practical to use in classroom learning while the results of the average percentage of lecturer responses are media aspects by 100%, material aspects by 100%, language and appearance aspects by 97% and sample problem aspects and training by 100% means that the lecturer in general considers this product to be very valid and practical to use in geometry learning in the class then the post test results obtained by the average value of the experimental class better than the control class are 78.33>60.66 and t count<t table is 1.28<1.65, so that, this product is effectively used as a medium of learning mathematics for the mathematics education Walisongo State Islamic University Semarang.
