Logic mastery makes the hard, easier. Logic mastery  leads to better, stronger and richer comprehension.  Logic mastery  improves reading and writing.  Logic mastery ease learning difficulties.  Logic mastery gives a headstart.  In sum, logic mastery  will develops critical thinking, improve reading and writing, and give a firmer base for work and studies at many levels. Good luck.

What may be learnt and when depends on how skills and concepts are developed. Making the hard easier and clearer will allow earlier & richer development of skills and concepts.

Foreword 

Four principles offer an inductive philosophy for the explanation and comprehension of math and reasoning skills. Three of the principles were met in a course on how to teach Nordic, that is cross-country skiing. The course was taught one weekend early in 1981, by an instructor-trainer from CANSKI, the CANadian association for Nordic SKIing in Flin Flon, Manitoba. Nordic ski instruction may begin with a lesson on how to put on the boots and attach them to the ski and also how to hold the ski poles – to be precise one holds not the poles, but their straps in way that will guide the poles. 

There is a technique here, one that is not obvious. The course gave minute attention to the details which novice and even experienced skiers might not know. In this course on ski instruction, the more complicated movements or skills were deliberately preceded by simpler motions. Each of which was easy to describe, master and/or review separately. This course turned Nordic ski instruction into an art. The four principles follow.

1. Each discipline needs to be presented, so that students understand what they are learning and why. Without a knowledge or an opinion of why, students may lose interest and not go further. The why could be approximate — a little uncertainty leaves room for thought.

2. Pathways through easily described and repeated ideas may extend knowledge of any discipline, area of thought or belief. One or more paths through easily described and easily repeated topics may allow those who travel further to tell others willing to listen, what to expect and again possibly why. Of course, differences of opinion exist on which disciplines should be taught or what pathways in them should be followed.

3. Awkwardness with an idea or skill often signals difficulty with previous ones. It may indicate at least one earlier skill has been missed or forgotten. When an awkwardness is felt or seen, learners should go or be taken back to practice the missing skills, more precisely the ones just before them. This retreat aims to restore confidence and build skills, so that the learner can go further. This requires a diagnostic skill – a knowledge of or opinion on how the topics in question can be organized and taught. Here again opinions may differ.

4. Each collection of mental and physical skills should be organized into a ladder-like sequences of steps with the basic ones first and the more advanced ones second. Learning in any subject stumbles when a first or succeeding step is not easily reachable from those before them. [1] To climb a ladder, the initial steps must be reachable, and each further step must be reachable from the one or ones before it, else failure occurs. Explanations should follow chains of reasons or persuasion which begin at the level of the student.

In mathematics education there are two barriers to comprehension to be lowered or removed. First, the algebraic or symbolic way of writing and thinking is better seen and read silently than read aloud or spoken. This has been an obstacle to the comprehension and communication of mathematical thought. Second, the deductive nature of formal mathematics exposition with its long chains of reason and preparation implies that concepts appearing at the end of a course are not comprehensible to students in the middle of the course nor at its beginning. Mathematics beyond the last concept mastered may seem impenetrable and mysterious.

To lower both barriers, students may be given lessons, easily described and repeated, which require a minimal formal comprehension of mathematics and logic while presenting ideas essential to deductive and to algebraic or symbolic thought. Recognizing, collecting and offering first such lessons may extend the common knowledge of mathematics beyond the mastery of arithmetic, counting and simple formulas that should be obtained in elementary school. This work identifies such lessons and indicates ideas for math and logic instruction from primary school to the start of college. Some of the ideas may be worth reading, repeating or refining – the three Rs that this author hopes for.

Postscript: The jumpmath program unconnected to whyslopes.com says the following: One feature distinguishes our workbooks from regular math textbooks, however: in the JUMP workbooks, teachers are consistently shown how to help students who are having trouble moving forward by breaking mathematical concepts and operations into the most basic elements of understanding and perception on page 2 of the Jump Teacher Manual - Fractions, one of three plus pdf files in the Jump publication page. The quote italized here complies with inductive principles given above.

-Inductive principles for course design & delivery  require a clear description of where and how skills and concepts may rest on earlier ones, so that difficulties may be explained and remedied by looking for  what was missed or forgotten in earlier studies. 


Mathematics is a demanding subject. All errors in notation and comprehension need to be identified and corrected. In reading, spelling and writing, students have to learn all the letters in the alphabet, not just some. and memorize spelling. Anything less implies difficulty.

Likewise in mathematics, students have to master key skills and concepts, one at a time and one after another. Anything less implies difficulty.


Modern mathematics curricula introduced an inconsistency into course design and delivery. They did not sanction the use of decimals nor the use of diagrams in skill and concept development but decimal arithmetic and diagrams are needed for student comprehension and for an operational mastery of quantitative skills. That implies the need for an mixed-math curricula based on a systematic development of operational skills, sufficient for applications and sufficient to provide a base & context  for  the very optional study of pure mathematis.
