solving process. Since there are many established heuristics (strategies and techniques), a good problem solver
should be able to select appropriately one or a combination of available heuristics. The Find an Answer stage makes
use of students’ drawing skills. The use of mobile learning is made applicable at this stage.
In Reflect and Extend stage, answers are checked for accuracy to determine if the question has been answered
correctly. Creative thinking is maximized in this stage wherein variations to the original conditions can be applied to
create new yet related problem situations (Krulik & Rudnick, 1999). However, if students are taught these processes,
they are in a good position to resolve problems successfully (Krulik & Rudnick, 1999). The common heuristics
available include guess and check, make a systematic list, act it out, simplify the problem, look for pattern, working
backwards, use of diagram or model. Combination of Rudric & Krulik Problem Solving Model into Performanced
ased will make sure the tool effectiveness for TVET student. Figure 2.0 is diagram for Rudric & Krulik Problem
Solving Model.
