The integration of submicroscopic representations used in chemistry textbook sets into curriculum topics

Hrast, Špela (author), Ferk Savec, Vesna (author)

To support the understanding of chemistry concepts and processes at the particulate level, various representations are included in learning materials. This paper focuses on how submicroscopic representations (SMRs) are integrated into Slovenian chemistry textbook sets with respect to the curriculum topics for 8th and 9th Grade. Textbook set analysis is based on four holistic SMRs descriptors (direct, indirect, combined descriptor, and SMRs without descriptors), which support learners’ recognition of SMRs’ informational value at different levels by providing different accompanying SMRs add-ons. The textbook sets analysis revealed that the number of SMRs varies significantly with regard to different curriculum topics. The overall proportion of the descriptors that enable the learner a direct recognition of SMRs is low in all curriculum topics. Interestingly, the descriptors that do not enable the learners a direct recognition of SMRs prevail in textbook sets. To obtain more detailed insight into the criteria based on which the textbook authors integrate SMRs with various descriptors into textbook sets, further studies are necessary.

Abstract

V podporo razumevanju naravoslovnih pojmov in procesov na ravni delcev so v učna gradiva vključene različne predstavitve (reprezentacije). Članek se osredotoča na preučevanje, kako so submikroskopske reprezentacije (SMR-ji) integrirane v slovenske kemijske učbeniške komplete v povezavi z vsebinami učnega načrta za osnovno šolo. Izhodišče za analizo učbeniškega gradiva so predstavljali štirje holistični deskriptorji SMR-jev (direktni, indirektni, kombinirani deskriptor in SMR-ji brez deskriptorjev), ki glede na specifične opisnike SMR-jev do različne mere podpirajo učenca pri prepoznavanju informacijske vrednosti SMR-jev. Analiza učbeniških kompletov je pokazala, da se število SMR-jev močno spreminja glede na različne vsebine učnega načrta. Delež deskriptorjev, ki učencem omogočajo direktno prepoznavanje SMR-jev, je nizek v vseh vsebinah učnega načrta. Zanimivo je, da deskriptorji, ki ne omogočajo direktne prepoznave SMR-jev, prevladujejo v učbeniških kompletih. Z namenom pridobitve poglobljenega vpogleda v kriterije, na podlagi katerih avtorji učbenikov integrirajo SMR-je z različnimi deskriptorji v učbeniške komplete, so potrebne nadaljnje raziskave.
