Results of Research
The first part of the results of this study, relating to the success of teaching and pupils'
ability to use their newly acquired knowledge, was stated by analyzing the results obtained with
the control test. A key emphasis of the second part of these results is focused on the competences
acquired and developed by pupils either assembling or self-generating chemical models.
Achievement of Pupils on the Control Test (Three Weeks After Performed Activities)
Figure 1 and 2 present the achievement of pupils in the control test:
(1) The average values of the results obtained in Tasks 1 - 4 and the total test (result on
the graph with the number 5) in relation to different teaching strategy - assembling (control
group) and individual designing (experimental group) of models (see Figure 1);
(2) The average values of the results achieved on Tasks 1-4 and tested together with different
types of models (commercial, paper, wire), see Figure 2).
The results in Graph 1 show that the pupils who assembled pre-fabricated models as
the control group achieved the minimum score on the test (on average 45.36%). Pupils who
were exposed during the learning only to self-generation of models achieved results that were
on average 6.00% better result, namely 51.43% (this is the number 5 on the x-axis, i.e. the test
items on the graphs). Pupils as model generators better solved all individual, separately controlled
tasks except Task 2. The biggest difference in performance between individual pupils’
groups occurred on the task 3 (EG was in 15.65% more successful), which verified the content
objective realization in teaching this topic, and Task 4, where the difference between the two
groups was as high as 19. 62%.
