Teachers who are knowledgeable about math concepts and recognize the prerequisite skills for constructs they are teaching as well as how the constructs they are teaching relate to subsequent knowledge and skills. In other words, teachers" knowledge and understanding of mathematics influence their instruction. School curriculum and materials also influence students" performance in mathematics. Schools that have a well-conceptualized math curriculum with necessary materials and resources are more likely to develop successful math instruction. The learning characteristics of students and how instruction can be modified to support their acquisition of mathematics knowledge and skills. 1. page 362: four variables that can influence math ability. Cognitive factor such as distractibility and cognitive learning strategies. Education factors such as the quality and amount of instructional intervention across the range of areas of mathematics. Some examples are computation measurement time and problem solving. Self-regulation factors such as persistence, attitudes towards mathematics, and math anxiety.
