Eric.ed.gov – Provoking Mathematical Thinking: Experiences of Doing Realistic Mathematics Tasks with Adult Numeracy Teachers

eric.ed.gov har udgivet: This action research project looks at what happened when a small group of adult numeracy teachers with widely different experiences of learning and teaching mathematics explored their own informal numeracy practices and undertook a series of collaborative mathematical tasks. Evidence from qualitative data collected during the enquiry suggests that “realistic” tasks can provoke a range of mathematical thinking and learning responses which allow us to identify ways in which “procedural” and “conceptual” thinking is being used, and to track learning journeys through different stages of problem-solving. Although more experienced numeracy teachers could move between and within their “real worlds” and “maths worlds” with intent and ease, others had less integrated experiences, often valuing perceived mathematical powers over their own intuitive powers, with mixed success.

Abstract p-Values are viewed by many as the root cause of the so-called replication crisis, which is characterized by the prevalence of positive scientific findings that are contradicted in subsequent studies. The spectrum of proposed solutions includes redefining statistical significance, abandoning the concept of statistical significance, or eliminating the use of p-values altogether. The unintended consequence of these proposals has been confusion within the scientific community, especially in the absence of consensus or clear alternatives. The goal of this… Continue Reading
