Title: Developing a Local Instruction Theory for Learning the Concept of Angle through Visual Field Activities and Spatial Representations by Bustang

One of the materials which students tend to have misunderstanding is angle. Even when students could distinguish the name, some of them still have difficulty when come to draw the angle. This situation is happened to some of my students back then in my working place. They can name the angle, but they did not have the right concept of those angle. They cannot fathom the meaning behind those angles.

This paper will tell us about learning activities (HLT) which worth to try by teachers when teaching angle. However, because this design research creates only a local instructional theory, the HLT should be modified so that it would suitable for other classroom.

There were 4 main activities that Bustang developed, to make the students mastering angle. This reflection paper would only describe those activities in general. When one needs to find more information about those activities, one just has to look up in the actual paper.

The first activity proceed was a spatial representation task “Now you see it, now you don’t” where the student investigated the real situation represent vision line and blind spot. The second activity was constructing vision lines and blind spot while the third and fourth were coloring the blind spot and constructing angle of vision.

According to the researcher the notion of angle was emerge when students draw the vision lines resulted from some observations. However, the researcher also found that even when students can remember what they experienced in the field activities did not guarantee they would be able to construct the abstract concept of the materials. Students also still carry a misconception of the angle’s size which related to the length of the arms. In the end, the researcher suggest to adding an activity which will make students ease this misconceptions by focused in validating the results of angle’s measurements.

To sum up, what way teachers choose to make their students understand was simply an easy pick. There were lot of research where teachers welcome to modified, so that they did not need to think of the activities plan from the very beginning.
