Implication

Qualitative ethnographic study reveals plane geometry and proportional reasoning in traditional Toraja cake making, highlighting its potential as a contextual mathematics learning tool.

Key Points

Identify the mathematical concepts embedded within the traditional preparation of Deppa Tori' cake and examine its utility as a contextual resource for school mathematics learning.
Conducted a descriptive qualitative study using an ethnographic approach focused on the Toraja community.
Gathered data through direct observation, semi-structured interviews, and documentation of Deppa Tori' production.
Analyzed data via source triangulation comparing observational, interview, and photographic evidence.
Traditional cake makers intuitively apply ratio and proportional reasoning during the measurement and preparation of dough ingredients without formal instruction.
Cake shaping and cutting processes directly incorporate plane geometry principles, specifically generating two-dimensional rhombuses.
