Abstract

Reševanje tangram sestavljanke je aktivnost sestavljanja oblik in sodi na ničto stopnjo razvoja geometrijskih pojmov po teoriji Van Hieleja. Fokus prispevka je uporaba sedemdelnega tangrama s fotografskim ozadjem v šolski situaciji. Empirični podatki, pridobljeni s polstrukturiranim intervjujem na vzorcu 10 učiteljev, kažejo, da učitelji slabo poznajo uporabo tangrama v šolske namene. Predlagani intervencijski materiali so bili evalvirani skozi pedagoški eksperiment na vzorcu 31 učencev 2. in 5. razreda. Fotografija kot ozadje tangram sestavljanke je predstavljala kontekst danega problema. Raziskovali smo, kako fotografija v ozadju vpliva na uspešnost reševanja ter na motivacijo. Izkazalo se je, da je fotografija kot kontekst lahko vir motivacije tudi v drugem triletju osnovne šole, ki pozitivno vpliva na uspešnost reševanja.

Secondary title: The tangram in lower primary mathematics
Secondary abstract: The tangram puzzle is a shape composing activity that is appropriate for the O-level of the Van Hiele geometrical thinking development theory. The focus of this article is the applicability of the seven-piece tangram with photography background in a school setting. The empirical data, collected using a semi-structured interview on a sample of 10 teachers, shows that teachers' knowledge concerning the effectiveness of the tangram is weak. The materials were evaluated through pedagogical experimentation and included 31 students in two classes (2nd and 5th). The contextualized environment was reinforced via photography as the un-derlying context of the tangram puzzle. The materials enhanced motivation even in the higher grades of lower primary education and positively influenced the students' solving capabilities.
