Keeping Math Simple has changed its name to Mathematics for Teaching. It has also changed its URL (now at http://math4teaching.com/). The author of the blog, Erlina Ronda, is a fellow Filipino. Written below is her blog description.
This blog is my contribution to narrowing the gap between theory and practice in mathematics teaching and learning. It contains teaching tips based on current reforms in mathematics education and teaching such as teaching mathematics through problem solving (TtPS), developing higher-order thinking skills (HOTS) and mathematical habits of mind, variation theory, constructivist teaching, scaffolding learning, etc.
I believe that K-12 mathematics is about developing students’ mathematical thinking and communication capacities first, and, knowing mathematics next. Experience and education have also taught me that mathematical thinking, communicating mathematically, and mathematics are best learned in the context of solving problems and doing mathematical investigations.
I love to develop mathematical tasks and activities that involve basic mathematics concepts but has the potential to engage both teachers and students in higher level thinking. I am particularly interested in students’ learning trajectory for specific content topic.
My work includes doing research in mathematics teaching, writing curriculum materials and facilitating professional development programs for mathematics teachers. I taught mathematics for 8 years before my current work.
I recommend her blog because of her innovative ideas in teaching middle school and high school mathematics.
