2. Research Design Considering the number of classes that is given treatment is only one class in the
absence of comparable classes and control class, the research design used in this study is one group post-test design. the observations made after the treatment given
is called the post-test. Hence, the research design will be the effect of a treatment in form of teaching-learning process using Numbered Heads Together NHT, and
eventually the results of the treatment will be investigated using the post-test and compare the results with the school standard score.
