“…Noting various concerns, such as the lack of sound subject matter knowledge and the strong influence of prospective teachers' past experiences as students, the consensus in the mathematics education community is that it is essential to provide prospective teachers with ample opportunities to improve and transform their knowledge, beliefs, and actual teaching practice.However, what prospective teachers bring to teacher education programs is, admittedly, often difficult to greatly change in the limited time period.For example, candidates' beliefs about what to teach and how to teach it have been consciously or unconsciously developed through many years of observations of their own K-12 teaching practices, and it is almost improbable to completely transform their beliefs (e.g., Ambrose, 2004;Doerr&Lesh, 2003;Eisenhart, Borko, Underhill, Brown, Jones, &Agard, 1993;Thompson, 1992).…”
