Abstract:

Virtual manipulatives were used as an intervention tool between assessments to determine, through quantitative and qualitative data, their effect on developing conceptual understanding of mathematics. Fourth grade elementary students were selected to participate in this case study. The students were exposed to virtual manipulatives designed to develop an understanding of time, coordinates, the conversion of fractions, and the difference between area and perimeter. Furthermore, this study investigated barriers that students come across when using virtual manipulatives. Finally, this study reviewed the characteristics of virtual manipulatives to determine which types are more effective than others. The results from this study indicated that virtual manipulatives were successful in developing the participants' understanding of the mathematical concepts. Barriers to using virtual manipulatives came in the form of reading comprehension as opposed to technical problems that can occur when utilizing technology. Students had little difficulty using the virtual manipulatives; however, lower level students had difficulty reading the grade level text that was associated with them. Finally, the study indicated that the most effective virtual manipulative was engaging and simple to use.

Faculty Spotlight:

As a resident of sunny Southern California, I have been an educator of all ages, including graduate students, for just over 10 years. After experiencing different occupations from Advertising to Restaurant management, I found my calling as an instructor.

A professional hobby of mine and interest is the infusion of multimedia technology in education. I have had the privilege of being a part of the California Technology Assistance Project (CTAP). Through CTAP, I have been able to routinely meet with educators that use the latest advances in technology in their classrooms. The collaborations have been useful in the development of professional development classes that I coordinate within my school district.
