“…Such is the case for 'categorize' (Evnitskaya & Dalton-Puffer, 2020), 'define' (Nashaat-Sobhy, 2020; Llinares & Nashaat-Sobhy, 2021), 'describe' (Dalton-Puffer, 2004), 'evaluate' (Llinares & Dalton-Puffer, 2015;Whittaker & McCabe, 2023;Hasenberger, ongoing), 'explain' (Dalton-Puffer, 2004;Lose, 2007;Connolly, 2019), and 'predict' (a subcategory of 'explore') (Dalton-Puffer, 2007), though only a few have been validated in terms of usefulness by developing explicit teaching programmes. Work in this direction includes a study by Breeze and Gerns (2019) in a secondary-level CLIL history class, where some general CDF-related features were explicitly taught for 'describing' and 'explaining', four doctoral theses (Connolly, 2019;Gerns, 2021;Bauer-Marschallinger, 2022;Hasenberger, ongoing) and Nashaat-Sobhy's (2020) validated framework for working with the CDF 'defining' in the university setting. Classroom materials are now being developed to teach, scaffold and assess these CDFs in the CLIL classroom 1 (see Coetzee-Lachmann, 2019;DeBoer & Leontjev, 2020;Del Pozo & Llinares, 2021;Coyle et al, 2023).…”
