Semi-quantitative diagram about temporal evolution in basic physics   learning: a study with engineering students
  We show a new semi-quantitative technique of analysis about of temporal evolution of learning of basic physics concepts. In this technique we arrange a geometric diagram with the score and the homogeneity (H-S), in this diagram we have a quantitative and qualitative information about the learning of students and the effectiveness instruction. We applied this technique to study the temporal evolution of the graphical interpretation of motion in one dimension through tutorials in a introductory course physics with 20 students of engineering at the Universidad Central de Bogot\'a Colombia for a period of 6 weeks. We found in the general diagram that (Smax,Hmax)=(0.75,0.75).
