Data from a 15-itemLikert survey and open-ended responses reveal a strikingly asymmetriclearning profile: while students reported high cognitive engagement(mean = 4.30) and strong intrigue with the equipment (mean = 4.49),their psychomotor confidence was markedly lower (mean = 3.60). Notably,students expressed high attraction to the equipment (positive affect)alongside persistent intimidation and low confidence in data-drivendecision-making (psychomotor). These results suggest that while greenchemistry principles serve as effective cognitive and affective anchorsfor student interest, the technical novelty of flow systems createsa psychomotor threshold that current single-session formats do notfully bridge. Our findings demonstrate that measuring only cognitionand affect would obscure this bottleneck, underscoring the importanceof independently assessing all three domains. We propose that prelabfamiliarization activities, distributed multisession exposure, andexplicit linking of experimental steps to green chemistry principlescan support the development of technically confident sustainable chemists.","PeriodicalId":43,"journal":{"name":"Journal of Chemical Education","volume":"103 10","pages":"5422–5432"},"PeriodicalIF":3.0,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149173764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As such, they do not adequatelycapture the domain-specific cognitive demands that arise when learnersengage with chemistry-specific graphs. This paper introduces the ReceptiveGraph Competence Model for Chemistry (RGC-Chem), a hierarchicallystructured, domain-specific framework for the analysis, instruction,and assessment of receptive line graph competence in chemistry. Themodel comprises five hierarchically ordered levels, ranging from theidentification of individual function values (Level 1) to the integratedinterpretation of more than one graph (Level 5), and integrates twocomplementary dimensions: a formal-representational dimension addressingthe structural conventions of graphs and a domain-specific contentdimension encompassing the chemistry-related conceptual knowledgerequired for comprehensive graph understanding. The RGC-Chem was developedusing a deductive–inductive approach, grounded in establishedtheoretical frameworks and empirically refined through a systematictextbook analysis of 371 line-graph-related tasks from German secondarychemistry textbooks. The findings indicate that the model’scompetence levels accommodate the full range of graph-related taskdemands identified in these textbooks and support the model’spractical utility as a research and instructional tool. The paperalso discusses the model’s potential for task design, assessment,and instructional planning, as well as its current limitations, particularlythe need for empirical validation with learners. Overall, the RGC-Chemprovides a theoretically grounded framework for research and practicerelated to graph competence in chemistry education and highlightsthe importance of connecting graphical patterns to their underlyingchemical meaning.","PeriodicalId":43,"journal":{"name":"Journal of Chemical Education","volume":"103 10","pages":"5612–5622"},"PeriodicalIF":3.0,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149173377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
