new rules for teachers!

quoted from: http://edge.ascd.org/_New-Rules-for-Teachers-11-20/blog/6560482/127586.html

"new rules for teachers (11-20)
11. technology is not the magic secret to academic success; put a bunch of ipads in the
      classroom, watch the teacher spend of his time managing the ipads rather than teach the
      class.
12. all teachers must have unit plans; this includes teachers of autism students, severe and
      profound, incarcerated students or the physically disabled.
13. all students must be assessed; this includes students who are visually impaired,
      hearing impaired, cognitively delayed, or those with autism.

14. students should read the unit plan just as college students read the syllabus; kids need
      to know where the instruction is headed and what the assessments will be.
15. if you treat kids as if they are in prison they will act like inmates.
16. parents must know the grade level their kids are at, in reading, writing and math,
      forget grades! teacher grades are generally meaningless; cruel, harsh truth is the best
      medicine.
17. students must be taught to monitor their progress in a class, in relation to the common
      core standards, not just the teachers' grade book.
18. the whole point of the assessment is to determine the extent of student learning, not to
      trick them into being wrong!
19. when a teacher or other staff member stands by the time clock everyday, just waiting for
      the moment when they can punch out and go home, they are yelling out loud their
      commitment to the children.
20. differentiation does not mean dumbed down!"

4th new concept "roller suction effect" (roller skating)

the "roller suction effect" is the 4th new concept introduced, as intended & written (2/7/13)
(r.s.e. - conceptual approach, through cross industry knowledge)

applicability: spoke roller skates - spokes circumferentially disposed like fan blades.
                     the above mentioned example has been chosen, for it is intuitive;
                     for other spoke roller types, aerodynamic - in the spin :) - testing advised.

advice beforehand: when skating on this type - always avoid too dusty or too wet tracks.   

for this type of rollers, only heavy duty bearings would be a good option.
please check this out with your bearings' supplier.
to be continued...

lower the bridge Dooley! :)

if you are a parent of a cool teen, and his evolution may seem out of order to
you, our advice is:
lower the bridge Dooley! :)
as absurd as it may seem, but for us, you don't  "have" enough "paths" to his
heart & mind...
"there can be no keener revelation of a society'soul than the way in which
it treats its children." (Nelson Mandela)

about the mountain bike subculture.

this post is:
- offered by the author - a la memoire de lieutenant Jean Bastin,
  ww1 french heroe - author of:
  "la lutte pour la liberte, mes dix evasions. 1914 - 1917",
  ("un récit absolument extraordinaire d'évasions ratées au dernier moment
  et souvent par malchance ou hasard puis enfin celle, la dixième, réussie
  après la traversée de pratiquement toute l'Allemagne. certains, peu nombreux,
  ne se résignent pas à être éloignés de leur patrie.")
  thank you Mr. Jean Bastin!

- an analogy, but respects the general rule of the blog,
  (... would not venture into other sports.)

- meaningful teenwise mainly, the true teens' self esteem -
  neither shaken, nor stirred here ever, :)

is crowd skating on speed skates, more like riding a mountain bike in a city?

yes, your speed skates (or mountain bike), might give you that "extra thrill" of
freedom, nonetheless you will be forced to adapt to the existing environment.
Mr. Jean Bastin did it 96 years ago, certainly you will succeed too;
the only question that remains is: your number of failures was?

good faith in good taste.

debating:

a. good faith in good taste? - lit., :)
  ex. 1: good faith in "a la grecque" recipes, would help you reach a more subtle "a la grecque"
           taste? (d.i.y. repeteadly).   
  ex. 2: good faith in "al dente" recipes, would offer you a more varied taste of "al dente"?
           (d.i.y. repeteadly).

b. good faith in good taste? - fig., :)
  ex. 1: good faith in "art nouveau", would build your taste in academic art, even further?
  ex. 2: good faith in "der jugendstil" (art nouveau, :) ), would suit your taste of Wien &
           its heritage, even more?
          
the examples are just questions to ask ourselves, ...
..., but don't limit these to the above ...! :)

..., more here, than meets the eye, ...

did food ever fool you?

this post is offered by the author - homage to those affected by
peripheral neuropathy, ... some of these cannot skate any longer :( ...
this aproach is mainly statistical (consequently original).
the conclusions to this case study should be your own and may or may not be
extrapolated to other serious human health conditions (cancer etc.)

 a.
 an increased overall toxicity of your daily lunch (... and/or breakfast, ... dinner)?
 how could this be?
 if you're not up to date with the term: "processed food" you might experience this toxicity the
 hard way...
 please keep in mind, at all times, that even when you cook for yourself (different courses for
 lunch, etc.), this also is food processing.
(b.
 an increased alcohol intake/day?
 c.
 an increased consumption of combustible tobacco/day?)

so, is there  a problem with these? yes, unfortunately, it might be...

might this also be a new insight on why everybody discusses only calories/day (of
different courses), and not their combined and/or cumulated overall toxicity/day?
we think so.

a, (b, c), a direct consequence of: "people being slaves of their own habits"?
more than probably.
about a.: it's not that we "aggress" ourselves (daily even - d.e.), it's that we are
"aggressing" ourselves (d.e.), without the necessary  knowledge about toxic
compounds and/or byproducts the food that we're eating/day, may contain.

liners - the "inside job"? (an all sports issue?)

yes, this is an all sports issue, excepting those done barefoot. :)

in skating, skiing, cycling, ... ballet even:
is the liner inside your sport shoe..., the "liason first officer", between you
and your exceptional sport performances? certainly yes!
don't use counterfeit sport shoes, or counterfeit liners inside your skates...,  if performance
is what you are after.

ex: what could one say about the compressibility of his skates' liner, if  soaked in 
      perspiration? how might this affect his overall skating performance?

liners, inside all our sport shoes (any detachable parts, shoelaces even) - do we really know
how to replace &/or customize them, to improve our performance? 

be advised, some of the detachable parts could require custom re-engineering:
a. a choice of other materials, than the initial ones, could be beneficial.
b. remodeling the inside of a sport shoe (not a simple task, although may appear as such.)

sorry, further suggestions here, would only be given directly to those interested (e-mail)

welcome to RollersBagneux!

a warm welcome to RollersBagneux! (Club de rollers de Bagneux, France.)
they are a section of the Club Olympique Multisport de Bagneux, association sportive régie
par la loi du 1er juillet 1901.
we particularly liked their: "Balade a Paris"... check it out!

the "behavioural dyspeptic" - a case study?

the "behavioural dyspeptic" is the 3rd new concept introduced, as intended & written (2/7/13),
(b.d. - conceptual approach, through cross disciplinary knowledge).

this approach might give you another insight, if you try to address & answer some of your
own nutrition related problems & questions. 

the aim here?
- help healthy people achieve a better skating experience, by emphasizing more on -
   the way & what they eat - strictly to their own benefit.

if you have any nutrition related organic condition, or experience sudden loss or gain in weight,
please seek medical advice at all times & address any of your problems to your general
practitioner, or ask for other appropriate medical assistance in your area.

this post is:
- addressed exclusively to healthy people who seek minor adjustments
   in weight and/or muscular mass, so their skating experience could improve;
- strictly related to skating (r. s. & i. s. - freestyle), as we would not venture with opinions,
   into other sports;
- only referring to: slightly overweight or slightly too thin individuals, as first exterior signs
   of ill-nourishment might be just these;

what to eat? calories, vitamins, carbs, fibers, fat, proteins,... who didn't hear about...?
cook to eat? how is your cookin'? ex: does acrylamide ring any bells?
how to eat? how is your eatin'? ex:  one of John's biscuits ( :) still around) asked him:
                                                       ... chewing too fast?
...

currently we try to outsource (flyers print), pls. tell us if you could optimize
the layout for as many flyers, as could be printed on an A4.

skates' assessments done for pros, cannot be published, sorry.

for figure skating, yes, s.p. and c.c.s. are applicable too;
(further details, only by e-mail).

2nd new concept: "critical contact surface" (ice & roller skating)

the "critical contact surface" is the 2nd new concept introduced, as intended & written (2/7/13)
(c.c.s. - conceptual approach, through cross industry knowledge)
it represents the blades'/rollers' minimal total surface area, in full contact with the
skating surface, at a certain moment during skating, beyond which the skater looses.
grip (slips & might fall) and eventually traction (often just partially).

attn: (r.s.) consider replacing the rollers on your skates, right away, if their surface appears
                pitted by craters (mm wide), particularly in speed skating, downhills and/or if you
                are overweight.
                from now on, we will call the rollers, with this type of wear: "pitted"
                (not the same as "pitting" - localized craters on a metal surface, associated always
                with corrosion.)
 the analogy for roller skating (not done 2/7/13), is to be added (using c.c.s.) here below:
 
               

overweight, but want to skate?

first, to all of you, trying to reduce weight this way: respect!
this post is exclusively dedicated to you.
is your body dynamics influenced by overweight? yes.
(here below, comparison overweight/normalweight would be more relevant, if made
between approximately same height & same sex individuals).

how could you avoid skating associated accidents &/or incidents, as much as a normalweight?
simple enough! ex.:
does the kinetic energy (at any given moment) of skaters skating
(overweight and/or normalweight), depend on their body mass & velocity? yes it does.
if your body mass is over your normal value (overweight), for a comparable
kinetic energy (to that of a normalweight), when skating, what would you
control &/or decrease first? (to keep yourself, in the same "risk zone" as a normalweight)
certainly, your speed!
- would you try to skate slower? 
- if you're a skater with a speed addiction, could you become an ex-addict?
  (at least until you reach your normalweight.)

would analogy reveal the unexpected & lead you, to the same outcome, for:
- rotational kinetic (turns, etc.),
- potential (downhills, jumps, etc.),
energies? :)

1st new concept: "secondary play" (ice & roller skating)

"secondary play" is the 1st new concept introduced, as intended & written (2/7/13)
(s.p. - conceptual approach, through cross industry knowledge)
it represents the axial and/or radial play of the:
(i. s.) - grinding wheel, relative to the shaft it is mounted on;
           (could appear when the grinding wheel is/becomes loose, or is fixed/becomes
           decentered, on its rotating shaft; dangerous, as the grinding wheel rotates at high speeds;
           serious injuries may occur, by flying grinding wheel pieces, if this breaks while
           rotating, due to this type of  play; always keep in safe distance  from a sharpening
           machine in operation.
           the grinding wheel's secondary play (axial and/or radial), even taken without any
           abnormal values of the axial and/or radial play of its shaft bearings, could mean damages,
           even beyond repair, to the ice skates' blades.
(r. s.) - rollers, relative to the bearings they are mounted on
            the rollers' secondary play (axial and/or radial), even taken without any abnormal
            values of the axial and/or radial play of  their respective bearings, could mean serious
            crashes, particulary in speed skating, downhill, etc....

bearings' axial and/or radial play, became so much more important in ice & roller skating
competitions, of any kind.

secondary play, as a new concept, for the first time defined, might only add up as information
for the casual skater; but in terms of competition & performance in skating, plays a role & has
to be dealt with, accordingly.

is bearing axial & radial play increasing your drag? (ice & roller skating)

adjusting your position, clothing and equipment, to reduce your drag, so that you get the most out of the power you're putting in - is this the idea? yes it is.

here, at this stage, we will only refer to:
- ice & roller skates (equipment),
- used (more or less) bearings - with a play (a &/or r), out of the manufacturer imposed limits.
the analogy (unusual) between ice s. & roller s., will be made on grounds of this play (a &/or r).

bearings are assembled with a slight amount of looseness between the balls and the raceways.
for further research related to bearings' axial & radial play, please take your time & visit:
JESA, Swiss bearings manufacturer.

schematic analogy r.s. - i.s.:
r.s.: a &/or r play (if any), of the rollers' bearings -
i.s.: a & or r play (if any), of  the grinding wheel shaft's bearings - when sharpening the skates -
could increase your drag & alter your intended trajectories, when (r. respectively i.) skating?
unfortunately yes.

suggestions welcomed...

we:
- would like to thank all those that gave a thought & visited this blog.
- also, take this opportunity and let you know, that we will offer free advice and support -
   couching one would be skater in Vienna, Austria, aged 10 - 14 - (humble beginnings -
   nonetheless gifted). please just let us know. (austrian residents - please do not insist
   otherwise).

our thanks also, to those companies, that brought (in all confidence) adverts to this blog.

suggestions welcomed...

... "sharp" enough with your skate sharpener (s.s.)? (ice skating)

the following text will give you some generic insight into how one should interact with his / her s.s.,

a. the ability to analyze what your s.s. says, helps you gain insight into his attitudes.
b. interact more with your s.s.., ex:
    - ask questions.
    - explain him what are you after (speed, crowd skating, competition, etc.).
c. try to "monitor" his craft:
    1.  visually check your newly sharpened skates (hollow, etc.), after each sharpening.  
    2.  mentally compare with past sharpenings, in terms of gliding, breaking capabilities, etc...
         (very relevant , if done repeteadly on the same ice surface)
    3.  interpret your "feet feedback".

optimal correlation: c1 visual check - c2 mental comparison - c3 feet feedback - ice surface,
will make you break through present limitations, in ice skating.

(analogy for roller skating, comin' up,... :) )  

you might be surprised to find out also, that among the best s.s. , in your area, some (the very best), take the initiative first & ask you a lot of questions, about your skates & skating style, etc. even before starting to sharpen them. (the s.s. tries to be consistent in what he does for you, so we think, his attitude should oblige).

we will introduce later, other concepts, related to the geometry of the skates' blades (but not only), slightly different from what you already may know.
this knowledge, never before published, which might fill in some engineering gaps, surely would enhance your skating capabilities & experience.
   

does your study buddy skate? (ice & roller skating)

does your study buddy skate?

is skates' choosing difficult for you?
can't decide yet? ask your study buddy what he would choose...
you might be very surprised to find out his opinion. why?

suppose, for example, your intention might be to do some crowd skating 
(this being also a reason, for you to choose a certain pair of skates..)
you also certainly would like to find out more about his / her skates, but quickly you
take notice that very little he /she says. why?

at a certain point, everything about skating becomes "second nature"?
we think so. (perfect skater wanted - "on earth" or on ice? :) )

but, could "second nature" also lead you, to better skating performances?
we think so, :)...

if you fall, try to land on your bottom??? (ice & roller skating)

"try to land on your bottom, if you fall", was/is an "advice" that left/leave us speechless, each time we heard/hear it.
therefore we decided to publish the text below ("a warned he/she counts for two."):

definitely not!
surely, landing on your bottom, could be the worst fall you could ever experience, particularly if you will land on it, upright.

attentive should be those:
- suffering from scoliosis, lordosis, ...,
- who suffer from overweight,
- with a clinical history of discopathy (risk of further intervertebral disk/disks damage) and/or
   osteoporosis (risk of vertebral fractures).

please take into account that we are referring only to traumatology statistics.
under no circumstances, could our opinion replace that of your general practitioner or specialist,
please seek their advice, at all times.

sharpened skates? (ice skating)

sharpened skates? a bold question with a nuanced answer? why?

1st homework: questions a & b, :)
a. are your newly sharpened skates useful enough, if you are skating on a poor quality and/or soft ice?
b. are your less sharpened skates useful enough, if you are skating on a mirror smooth and/or hard ice?

our answer:
keep your skates sharpened according to the ice surface. - easily said than done?

all skaters are interested, to reduce drag on the ice and make the most of their momentum (even beginners, in their instinctive reactions...) but, regarding their skates, do they really pay enough attention to how:
- suitable is the pair, for themselves?
- sharp should they be, given the ice surface? (indoor/outdoor ice rinks, crowd skating...)
- stiff and/or tight, they have to be? (once put on...)

foreword

here, an engineer offers you skating related facts, in detail. (ice & roller skating - free style)

did you ever think that you might improve your experience on skates, by "listening" to what your feet "tell" you while skating? :)

we will begin our story by bringing applied engineering to your finger tips (toes :) ), so you could avoid incidents and/or accidents, while skating; moreover you might improve your skating style using simple rules & techniques.

is skating smoother & improved peformance, of some interest to you? then, be on line and
on skates after... :)
