Streaming by Student Cooperation

The student right to a good education ends where he or she disturbs the education of others. The students right to good education also requires course materials to be clear and readable to allow self-instruction and also requires instructors versed in mathematics to teach the latter. Anything less may be grounds for student alienation, lack of cooperation included, and parental protest. This essay on streaming students by cooperation is premised on the notion that course design and delivery is sound. I have seen situations where both course design and delivery are unsound, and students are brow-beaten by teachers and school counsellors to behave. Bullying in schools is not limited to students.

Discipline When Education is Inclusive

Some school are able to expel difficult students. But many other schools or school boards cannot expel difficult students. Where that occurs there is still a possibility of providing quieter and better schooling. Let students level of cooperation with their teachers decide in which classes students are placed - make access to some classes conditional on good behavior and on cooperating with the instructor.

How does one in general provide teachers with easier classroom management in public secondary schools and at the same time provide a better and safer school environment for most students? One answer is Let the student decide. Let the classes or streams in which they are placed depend on their cooperation with instruction and perhaps on their abilities. With students who cooperate, teachers may be able to provide multilevel instruction - not a simple task - by enlisting more advanced students to aid and tutor struggling students. Students who cooperate may be placed in larger classes where teacher subject knowledge is more important than classroom management skills. Non-cooperative students may be placed into smaller classes.

Imagine an instructor Henderson with a subject expertise in say chemistry or physics, and great talent for skill and concept development there-in. In the school, the principal should be able to tell students, Henderson is a great teacher but to be Henderson’s classroom you have to co-operate and be well behaved. Otherwise, you will be expelled from that class and put somewhere else. Then student in Henderson class will have a good learning environment and a chance to sit down and study. The chance to be in such an environment in physics or mathematics or another subject may drive students to be well behaved. No force is involved.

The stark message that student will be streamed not by academic success, but according to their classroom behavior, could lead - a hope not a guarantee - for classrooms where learning and not agitation is the main objective. Student will wanting to stay in such classes or be promoted to them will have incentive to behave. The otherwise boisterous student who wants to learn may then decide to control his or her behaviour alone or with advice from the school or parents. Thus firm limits and natural consequence of lack of cooperation are set. It is cruel to be kind. Give students responsibility. The introduction of such streaming may take a few months or years, but as it proceeds students will strive and their parents will lobby for access to the stream noted for student co-operation in their own instruction.

Mixing Large Group and Small Group Instruction

Students who decide to behave may be placed in larger groups as classroom management is less difficult with them. That re-grouping could release teachers for the small group instruction of the difficult students. We hope that latter are not deliberately difficult to have small group instruction. No scheme is perfect. The instruction of that small group may have to be shared between those teachers able to manage difficult students. Each teacher is different. There is no need to insist all instructors who works well with cooperative students have the ability to work with the difficult ones at the start of a teaching career. 

The onset of teenage years or puberty is a time of unsettling changes for students in which rationality may not always be present. The teen that is difficult today may become more responsible over time. The growing teen is not on drugs, he or she is on hormones whose effects are unpredictable and whose effects will hopefully reduce over time, so that growing maturity is seen. In this matter, there will be invariably students who are difficult, who do not see the point of being in school or lack self-control. That is where small group instruction and guidance counselors may help. Leaves from education to work or not, to see need for self-application may provide the motivation and self-control needed for a student to cooperate in their own education.

A student who is difficult, there is always hope, may decide later to settle down in order to have the fruits of a safer learning environment. The hope in the foregoing is that students will decide to behave.

The Logic of Injustice: How Texas sent an innocent man to his death - The wrong Carlos. Some judgments are irreversible. Procescution: Where and when prosectors play to win rather than for justice, guilt beyond a reasonable doubt goes unrespected due to prosecutors who putting winning first, those innocence before the law may be convicted. Some procescutors offices in continuing to accuse after a pardon due to reasonable doubt or innocent being shown, may sucessfully oppose compensaton for false convictions by asserting a pardon individual is still under suspicion. Then the pardoned individual or the latter's estate is not compensation for years or decade of improper or false imprisonment, or for execution. Site chapters on Logic
and some in Pattern Based Reason may slowly lead to greater precision in reading, applying and writing laws.

Parent Center: Help your child or teen learn:

Parent-friendly Work Booklets for ages 3+ to 13 Use these or others to check or build skills. Other booklets are available but these booklets allow parents unsure of themselves in mathematics to help their children. The selection acquired in Canada is published in the USA. So it has a US orientation. In retrospect, the selection shows parents what to check with the booklets or by other ways, the choice is theirs. But in retrospect, the selection does not cover integral and fractions liquid weights and measures - ask the publishers to correct that! For ages 9 to 12 say, parents may compensate by showing boys and girls how to use weights or mass, and further measures in food preparation. Beyond that children may be shown how to measure and calculate angles, lengths and areas [proportional amounts too] directly or by using maps and plans drawns to scale. Learning how to gather and measure all the ingredients, pots and pans for a dish or a meal, along with cleaning up sets the stage for like activities or experiments in science courses, and in developing organizational skills, gives boys and girls a head start. Good luck.

Skills with take home value - A few ideas

Basic skills include time-date-calendar Matters; money matters; map, plan and scale diagram matters;counting, measuring and figuring; decision making with logic and likelyhood; being careful and being aware of the domino effect of mistakes; reading and writing with precision.

Is your child able to add, subtract and multiply amounts of money, work with fractions, work with clocks and calendars, work with maps and plans, and measure length, weight-mass and volume? Schools may promote your son or daughter without providing basic skills in reading, writing and arithmetic.

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.

The first topic leads to a full high school level theory for the forward and backward mastery of growth and decay models and for definition, range and domains of radicals, roots and powers. The next two topics make quadratics and polynomials easier to learn and teach. Site coverage of functions turns vertical and horizontal line rules into computation methods for evaluating functions.

As invited guest here and elsewhere, if one or more explanations is not to liking, try another. It may be better or just right.

Unsolicited Advice

Learning to do and high marks if it comes to easy is often deceptive - light rather than deep. For that reason, students with learning difficulties determined not to let it get in their way may go deeper and farther than those with none. High marks, if the come easy, may be deceptive - provide a too light and not a deep mastery. That could have been your problem in secondary school, one that leads to comprehension shock or difficulties in calculus and more generally in the first year of college. Bon Appetite.
