Welcome to the mathematics education revisited (essays, rants and proposals) site section. In the past essays and rants used to be spread though out site sections. Now they are all located in this site area. Section material represent reflections and reactions to what has been done in the past. When I first heard of constructivism in the 1990s, I read its then and revised principles and standards (NCTM emitted) to see what proposed in the hope of supporting local trends with a few methods (lessons that had worked) because I did not have an academic position, and prospect for one were dim. Instead I found myself in a counter-trend position with ends and values for mathematics education strikingly different from dominant position and more closely aligned what is called the mathematically correct. At the same time, constructivist calls to engage students, to provide rich learning problems and environments and to empower students through such environments had a strong appeal. They represented an ideal to strive.

My exploration and expression of ideas and methods for instruction stemmed from an observation of steps too large or gaps and eventually inconsistencies in skill and concept course design that the constructivist movement inherited from earlier efforts. I had some remedies which I felt compelled to explore and report. While the latter was motivated by the difficulties of my students 1983-89 while I taught in college posts, the remedies posted online 199502010 are too late for past students, but may be timely for their grand-children. That is another case of better late than never.

That being said, the constructivist principles or standard that true knowledge is a private affair, located in the mind, apart from reliable observation and testing, and not to be challenged because everyone's ideas and reflection should be respected, appears to be in contradiction with the old-fashion ends and values that called for observable skill development in a tangible or observable manner. Each of us in a daily lives from cooking to driving has and follow skills or routines to obtain repeatable and reproducible results. In that, there is an element of rote learning. In rules and practices are given and followed carefully (we hope) to avoid mistakes. Performance, know-how, observable skill development, does not require comprehension. They may be learnt by rote. For material ends and subjects in education, some practices may be learnt and combined by rote. But there may be intelligence or observable skill in learning to how apply implications, rules and practices carefully (avoid mistakes) and in mastering the further super-practice of how to combine implications, rules and practices to obtain more, all in an observable and recorded manner for peer- or self-correction.

The site two level framework POMME for Progressive (meaning step by step) or Practical Observable Motivated Mathematics Education is based on teachers and students being given or offered clear ends, values and methods for skill development via small and alternative step likely to work and likely to ease or avoid common fears and difficulties. The focus of instruction is on credible and reliable skill development. True skill development has to been seen and reliable to be credible. And this student confidence and self-esteem comes learning to do. The rich learning environment and problems currently sought to support constructivist may also lead to projects and paths that enrich and motivate observable and verifiable know-how development. POMME tangible ends and values provide a context and motivation for its methods, while it methods support the ends and values. In that, awareness of the domino effect of approximations and errors in figuring and reasoning may be both a method and also an end and value for instruction. So ends, values and methods for instruction may overlap.

Before the advent of POMME, many ideas were explored in formative essays. The essay still include reflections yet to be included in the implementation of POMME. Just for the record, this site has existed for a three to four years or not more.

About this Site

About POMME: In mathematics education, the question of which way to go is answered here by a statement and balance of ends, values and methods in a two level framework POMME for Progressive (meaning step by step) or Practical Observable Motivated Mathematics Education. The first level for the education serves common needs of life in the streets, or at home or at work, in many societies - developing to de-industrializing. The first level focuses on student centered skill development. The core of the second level represents preparation for college programs in scientific fields.

The second level core is subject centered in that students learn skills and concepts that may have intellectual value, but more importantly to society, prepares some not all for work in mathematical arts and disciplines - engineering, technology, business and money matters, and/or mathematics education itself.

The second level core is not inclusive where observable student performance in mathematics and other disciplines is employed for student selection by college programs. That selection may be described positively via talk of competitive spirit and giving the most able a chance to continue in the few space available in higher education. It may be described negatively as giving preference to some, not all, in terms of opportunity.A similar question of competition versus inclusion is met in the question of whether or not athletic activities are for competition or general health.

The first level aim to develop know-how and work habits with take-home value as long as that development remains simple. We may may also say the role of the second level is provide the less simple know-how with take-home value, and do that as early as possible for the sake of student centered instruction. That may offset content concerns, that is the mathematical demands of further instruction and/or competition for places there-in. While I prefer inclusion (helping as many as possible) to competition (selecting the few), I dislike more the existing state of secondary mathematics in which topics and skill development are not explicitly connected to common needs (even if they be years or decades later) nor explicitly to the needs of college programs in scientific and other fields. The ends and values of the two level framework may not be optimal, but if that is all we have to offer, they should be stated clearly and strongly. That being said, students gain self-esteem or confidence by being shown what to do in an observable ways, ways chosen to aid skill development and not to distract from it. The confidence and self-esteem that may follow from learning to do (see site methods to make learning to do simpler and richer) may compensate where the ends and values of instruction are not perfect.

Besides ends and values, POMME or site material includes content innovations and different starting points for skill and know-how development. Those starting or entry points are chosen to facilitate, optimize and not impede the development of skills and practices, those appearing in daily life and those appearing in scientific fields. Different starting points and starter lessons, all motivated by explanations of common content difficulties apart from context, make quantitative skills and know-how development richer and easier for learning and teaching. POMME and site material stands on and reacts to earlier paths for course design, on their strengths and weaknesses. Where the initial aim in writing was to address a few initial concern or content gaps, over time writing drifted to a more daring and bold endeavor of providing not only more and more different pathways for skill development, but also to provide context. Without that, mathematics skill development year after year, no matter how refined or polished, serves no ends and values.

Ideas and Principles For Instruction and Educational Reform

  1. Inductive Principles For Instruction - systematic skill and concept development.
  2. Fairness in Education - requires systematic development of all skills and concepts.

    Can education be fair if students are tested on natural talents instead of developed ones? Mastery of a skill, say the algebraic way of writing and reasoning, is regarded as a natural talent when and only when we do not know how to systematically develop that skill or concept. Site material reduces the number of natural talents required in the mastery of mathematics. Find the four skills for algebra in chapters 8 to 14 of Volume 2, Three Skills for Algebra, to see how to develop the algebraic way of writing and reasoning, and thus make mathematics fairer.

Logic and Reason in Mathematics

Mixing Rote & Thought-Based Development

  1. Cultivating Intelligence - Why value careful mastery of rules and patterns, steps and methods, practices, in a repeatable and reproducible manner.
  2. Multiply Kinds of Reason in mathematics - Essay I
  3. Multiply Kinds of Reason in Mathematic- Essay IIs - On the hierarchical development of rules and patterns, steps and methods, and practices in pure and applied mathematics (mixed mathematics). What is proof? What options are there for a thought-based development and verification of college and pre-college mathematics?
  4. Theory of Knowledge - Stories, Longer and longer
  5. Formal or Informal Peer Review
  6. Education in Mathematics, Science and Technology - All based on empirical verification and empirical skill development and verification. But in mathematics we can offer a full thought-based development while in science and technology, we can introduce the scientific method and introduce lab equipment, but can only provide a full-thought based development through visits to the lab and library. The lab alone is insufficient.
  7. Maths Instruction in General - Three Goals A B and C to Set for Student, Supporting those goals and why rewrite the curriculum
  8. Operational Viewpoint - Aim for an Operational Command of Mathematics First.- For students with no immediate interest in the know-why, a focus on the practice, an operational command of key skills and concepts may make comprehension later of the know-why easier and more appealing. The calculus teacher may says to students - learn to do now and to understand later.
  9. How to Set Standards for textbooks and course materials - Need for Inspection by University Domain experts outside of Education Faculties to ensure bureaucratic course design and textbook composition does not lead to nonsense in mathematics education.

  4. What Should be Learnt and When?
  5. Grouping Students - Streaming?
  6. Learning Takes Time and Effort
  7. Making the Hard Easier but Ignoring how and so missing the Point

  11. Euclidean Model for Development. Damage Reversal
  12. Educational Follies - Learning By Discovery incomplete, cannot work, compound difficulties.

  14. Modern Education

But teaching by indirect instruction requires not only a knowledge of what can be taught directly, but also a knowledge of how to explain all elements indirectly. Anything less invites or compound difficulties. Ouch.

Pre-Teen and young teen mastery of skills and practices which should be common with map-plans-diagrams drawn to scale, contour interpretation included, has actual or potential take-home value for daily- and adult-life in solving routine problems. Elevating some practices to principles, axioms or postualates, provides a base for analytic and Euclidean geometry, an analytic view of similarity, and an efficient mastery of trigonometry and complex numbers. Right triangle trigonometry provide an analytic alternative to solving geometric problems by drawing diagrams to scale.
