q1 · i? · qualitative · r3

Qualitative coding of classroom video from one kindergarten classroom's seven equivalence lessons. The article reports "38 instances of the GSIDES code", alongside 28 ISA, 26 BAL, 17 DEF, 11 GBAL and 6 FORM instances. Counts are descriptive; no test is reported.

"Across the seven lessons that addressed mathematical equivalence, we observed 26 instances of the BAL code, 17 instances of the DEF code, 6 instances of the FORM code, 28 instances of the ISA code, 11 instances of the GBAL code and 38 instances of the GSIDES code (see Table 2)."

Related Claims¶

• The kindergarten teacher explicitly discussed the forms an equation can take (FORM) with the goal of expanding the range of equations students would accept as valid — related
• After an early algebra intervention, the number of kindergarteners giving a relational definition of the equal sign went from one to nine, and acceptance of non-standard equation forms rose, as reported from the authors' earlier study — related
• Relational understandings of the equals sign are associated with middle grades mathematics success — related
• A procedural \"answer is coming\" interpretation of the equals sign leads students to chain arithmetic and errors on missing-number equations — related
