Vloge legende v kemijskih nalogah temelječih na submikroskopskih predstavitvah

Submikroskopske predstavitve, s katerimi je predstavljena delčna narava kemijskih pojmov, lahko pomembno pripomorejo k odpravljanju napačnih razumevanj in izboljšanju znanja kemije. Predstavljajo pomemben element različnih učnih gradiv, pri čemer se pogosto predpostavlja, da so jih učeči sposobni učinkovito uporabiti in interpretirati. Glavni namen je bil raziskati vlogo legende pri procesiranju submikroskopskih predstavitev med reševanjem na njih temelječih enostavnih kemijskih nalogah. Pri tem je bila izbrana in z uporabo očesnih sledilcev ter intervjujev študentov nekemijskih smeri preučevana lastnost slikovna oz. besedna oblika legende. Na podlagi pridobljenih rezultatov je bilo ugotovljeno, da študenti sicer enako dolgo rešujejo naloge s slikovno oz. besedno legendo, vendar se pri tem pojavljajo pomembne razlike pri razporeditvi njihove pozornosti med območjem s submikroskopskimi predstavitvami in območjem z navodili ter besedno oz. slikovno legendo. Študentje pri nalogah z besedno legendo porabijo za njeno procesiranje več časa in tudi nanjo v primerjavi s slikovno legendo večkrat fiksirajo svoj pogled. Rezultati tako nakazujejo na pomembnost vloge legende submikroskopskih predstavitev in opozarjajo na smiselnost njene vključitve v učna gradiva tudi z namenom razvijanja reprezentacijske kompetence, kar predstavlja s strani učiteljev in oblikovalcev različnih učnih gradiv pomembno spoznanje.

• Naslov: The role of the explanatory key in solving chemical tasks involving submicroscopic representations

Izvleček

Submicroscopic representations, that present particle nature of chemical concepts, can significantly contribute to the diminishment of misconceptions, as well as to the improvement of chemistry knowledge. They represent an important part of various learning materials, thereby it is often assumed, that the learners are capable of their efficient use and interpretation. The aim of the presented research was to study the role of the explanatory key in processing of submicroscopic representations while solving chemistry tasks that involve them. The pictorial and textual explanatory key was studied by the use of Eyetracker and interviews with non-chemistry major students. The results indicate, that students spent the same amount of time for task solving involving the pictorial or textual explanatory key. However, there are significant differences in their attention focused towards the area of interest involving the submicroscopic representations and the area of interest involving instructions including pictorial or textual explanatory key. Students tend to use more time for processing of the textual explanatory key in comparison to pictorial explanatory key and they also made more fixations on it. Based on the results, it can be devoted, that the key attached to submicroscopic representations, has an important role in processing information and that it is useful for students to include the key into learning materials. In such a way it is also possible to facilitate the development of students’representational competence, which is an important finding for teachers and designers of learning materials.
