This research aims at introducing a new suggested strategy, "QCEJ" strategy, identifying its impact on developing the skills of constructing scientific arguments, and determining the level of scientific argument construction skills among middle school students. Results have shown shortages in the level of argument construction skills in both cases of familiarity and unfamiliarity with science content knowledge and the impact of the "QCEJ" strategy on developing constructing scientific argument skills through teaching a chosen unit entitled "Matter and Energy" for grade (8) students. The study applies important applications in science education in general and scientific argument construction skills in particular.
