studentsAn overwhelming majority of the students felt that they were adequately prepared (81.3%) forthe first college math course, and on a scale of 1-10 they rated their math skills between 7 and10. They probably had reason to be confident since 82.5% had received a grade of either an A ora B in their last high school math course, as they had reported. Yet, roughly a third of thestudents surveyed reported that they had to repeat a math course in college. Calculus I andCalculus II were the two courses that were repeated most often with 31.4% of students reportingthat they had repeated Calculus I and 36.2% had repeated Calculus II.Perhaps a sampling of the responses to the survey question, “What was the biggest challenge inthe first math course that

The motivation forthis study was derived from Schunn‟s work but is different in that the measurement ofproportional reasoning was purposefully planned and included a sample size of thirty students,including a control group.Norton (2006) used a LEGO-robotics context to investigate the mathematics learning of 46seventh grade students. He found that (a) the LEGO-robotics activities afforded learningopportunities that also reinforced social relationships, (b) explicit scaffolding was needed bysome students to achieve the mathematics learning, and (c) many students were able todemonstrate greater than expected mathematics and science learning.

Researchers have actuallydemonstrated that if one utilizes technology systematically, it actually helps the instructoraddress perceptual dimensions of learning (Keefe, 1991). It is also important thattechnology should not be viewed just as a growing trend. It must be intelligentlyimplemented as an invaluable instructional tool that can accommodate diverse learningstyles of 21st century students (Watkins, 2005). Dr. Walter B.

As the number of layers increase,the deformation becomes more evident. However, the grooves become shallower and the 287surface becomes smoother.
