The objective of the study was to find out the effect of learning through Wireless technologies and the traditional method in teaching and learning Mathematics. The investigator adopted experimental research to find the effectiveness of implementing Wireless technologies in the population of B.Ed. trainees. The investigator selected 32 B.Ed. Mathematics Trainees from a College of Education in Tamil Nadu. Tools used were Mathematics learning package developed by the investigator and Achievement test in Mathematics developed by the investigator. In the experimental group, B.Ed. trainees were learning the Mathematics by Wireless technologies in their convenient place and time. The control group B.Ed. trainees were taught using traditional method. Findings of the study showed that there was significant difference between pre-test and post-test scores for the experimental group in learning Mathematics. That is experimental group B.Ed. trainees have achieved high in post- test than the Pre-test. And also there was significant difference in the Post-test Scores of the experimental and control group. That is experimental group B.Ed. trainees have achieved high in post- test than the control group B.Ed. trainees. The investigator concludes that the experimental group is more effective than the control group. Thus the Trainees using Wireless technology for their learning is more successful than the traditional method.
