Abstract:
This paper reports the use of Tracker as a pedagogical tool in the effective learning and teaching of projectile motion in physics. When computer model building learning processes is supported and driven by video analysis data, this free Open Source Physics (OSP) tool can provide opportunities for students to engage in active inquiry-based learning. We discuss the pedagogical use of Tracker to address some common misconceptions of projectile motion by allowing students to test their hypothesis by juxtaposing their mental models against the analysis of real life videos. Initial research findings suggest that allowing learners to relate abstract physics concepts to real life through coupling computer modeling with traditional video analysis could be an innovative and effective way to learn projectile motion.

Query A:
Author: Please check and clarify the first
sentence of the captions of figures 2 and 3.
Data tool display real data mass A y versus t =  Data tool display of mass_A showing y versus t
Figure 2: Line 4: b = -2.379 should be b = 2.379

the final statement could look like this.
Figure 2. Data tool display of mass_A showing y versus t view where the parabola fit equation of
y = a2t + bt + c is used with parameters a = −5.038, b = 2.379 and c = −0.003. By comparing with
equation (4y), it is determined that gy = −10.08 m s−2 and uy = 2.379 m s−1 respectively

"Figure 3. Data tool display real data mass_A of the x" could be "Data tool display of mass_A of the x"
final form could look like this
Figure 3. Data tool display of mass_A of the x versus t view where a line fit equation of x = at + b is used with parameters a = 1.733 and b = −0.005 as determined using Tracker. By comparing with equation (4x), it is determined that vx = 1.733 m s−1.


Query B:
Author: Figure 9 not cited. Please check.
insert (figure 9) into the Page 5 after "Expert students can be challenged to extend their own learning to model air resistance by comparing the trajectories of the dynamic particle model and that of the real video, and being convinced that the video’s projectile motion cannot be realistically assumed to be a motion with significant air resistance (figure 9). "

please note, you may wish to reposition the actual Figure 9 nearer to the Paragraph in Page 5?
