Read  logic chapters 1 to 5  in online volume Three Skills for Algebra  for greater skills & confidence in  work 
and study

 Logic chapters 1 to 5  re- appear not in sequence, as is or longer,  in  Volume 1A,  Pattern Based Reason, Bon Appetite.

Logic Mastery
 Amazing, Amusing, Amorous,  Delicious, Delightful, Edifying, Strengthening Elixir. 
It eases work & learning difficulties Makes the hard easier. Opens eyes. Leads to greater precision.
in reading and
writing

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.


After logic  (a) continue reading Three Skills for Algebra, chapters 8 to 14  and do so alongside site area on solving liinear Equations ; or (b) see this calculus starter lesson and Volume 3, Why Slopes  & More Math, chapters 2 to 6;

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.


Try the Twiddla Whiteboard. In principle, it  allows to people to draw and chat together online on a copy of this webpage or a clean sheet. The chat may be via text or audio.  Visit www.twiddla.com to set up whiteboards to work with the webpage of your choice.

Good luck.

4 Ways to Improve Education Reform

  1. Respect inductive principles for course design and delivery. 
  2. Test ideas for reform in optimal and sub-optimal conditions first - reform in haste, repent at leisure. Reforms like drugs should be tested before widespread use. 
  3. Provide materials and methods simple to understand and follow as a lower bound or safety net for teachers parachuted into unfamiliar topics. Do not assume that teachers are providing instruction within their area of comfort - an ideal situation, but one is too often absent in mathematics where two-thirds of instructors in North America, if not elsewhere, do not regard themselves as skilled and confident in mathematics.
  4. For instruction not streamed by ability, for instruction to be inclusive and for instruction of students with poor attendance, develop multi-term or multiyear, multilevel modules to favour self-paced instruction skill and concept mastery.  Include enrich material to slow the more gifted students while everyone else catches.

For instruction, teachers and mathematics education committees need to proactively collect and  review ideas for  not wait for others.  Course design and delivery, and approval of  materials or textbooks in secondary and even primary school mathematics  should include university professors of mathematics, so that content gaps,  inconsistencies and material that is not essential, your standard curriculum pitfalls, are flagged. Good intentions should defer to or combine with discipline knowledge.

The  invention or collection of appetizers and lessons easily understood and followed  in class BY TEACHERS  is one way to make learning and teaching more effective.  Some adjustment or variation will be needed for different cultures, different learning styles, in which students may be passive to active, cooperative to resistance, to instruction, voluntary to compelled. Modular course design may allow instruction to cope with multi-level classrooms and intermittent attendance. And where instructors may be given teaching assignments outside their zone of comfort or expertise,  textbooks and modules easily understood and followed by students and teachers could provide a lower bound for education, and in place of complete confusion may allow first-time  instructors in a discipline to be two pages ahead of students.

The question of how to develop skills and concepts, so the study of mathematics and logic seems purposeful and not endless remains open.  Primary school and junior high school mathematics could provide practical drill and practice on geometric and quantitative figuring and measuring skills and concepts needed daily life at work, in the home and in buying and selling, while offering or providing a thought-based development. But skills and confidence may come from the mastery through rote or comprehensions of methods which give repeatable, reproducible and hence verifiable results.  The direct and simple use of formulas, given if not derived, could be part of this wide ranging, preliminary and practical education. Saying and showing how to use measurement and mathematical methods in a repeatable and reproducible, and hence verifiable manner may be designed to help students who end their studies early while providing an invitation and a context for further studies. Ease of exposition and mastery would be the guide.  Details how need to be determined.

Hope for benefits, but look for the limitations first in any reform, and then provide alternatives.
