Description

A kind of Pu Feng throws pin experiment mathematical modelling machine and control system thereof
Technical field
The present invention relates to mathematics teaching aid field, a kind of Pu Feng throws pin experiment mathematical modelling machine and control thereof System.
Background technology
Probability, also known as probability, chance rate, probability (probability) or probability, it is the basic conception of theory of probability.Probability is Tolerance to the probability that random event occurs, the possibility typically occurred with one event of a real number representation between 0 to 1 Property size.Closer to 1, this event more likely occurs;Closer to 0, then this event unlikely occurs, and it is objective demonstration, and Non-subjective checking.
Probability Experiments generally comprises touches ball game, toss a coin, and dish of walking around is thrown pin test, thrown drawing pin and throw the experiments such as bottle cap,
Wherein, the test of Pu Feng throwing pin refers mainly to:
1) taking a blank sheet of paper, drawing many stripe pitch above is the parallel lines of a.
2) take the pin of an a length of l (l≤a/2), throw n time on the paper be decorated with parallel lines randomly, observe pin with The number of times of straight line intersection, is designated as m.
3) probability of pin and straight line intersection is calculated.
It is first example expressing probability problem with geometric format that Pu Feng throws pin experiment, and he uses at random experiments first Reason definitiveness mathematical problem, certain impetus is played in the development for theory of probability.
Above-mentioned experiment all should allow student do in person, and these experiments are fairly simple, and experimental result is the most uncomplicated, operability By force.The frequency that event occurs can be preferably known from experience by doing in person, and the contacting and distinguishing of frequency and probability, know from experience the most heavily During experiment, frequency can be as the estimated value of event occurrence rate again.
Student does toss a coin experiment in person and throwing pin is tested and had following effect:
1. contribute to the feature of students' response random phenomenon.Carrying out testing and in analysis to test data, student will Gradually realize the uncertainty of random phenomenon, and repeat the regularity that test is presented in a large number.
2., by Probability Experiments, contribute to student and clarify some wrong understandings.By in person testing, student can be in reality The uncertainty that thing occurs is known from experience in the middle of the process tested;The puzzlement that there is also for those, is not especially inconsistent with experience As a result, by experiment, clarify wrong understanding, allow student convince.
Existing the most toss a coin (throwing pin) experiment throws coin (hands throwing pin) often by a staff, and another people side is counted The mode of number is tested, but, more than the number of times of needs experiment, thus above-mentioned toss a coin (hands throwing pin) Probability Experiments Method needs to expend a large amount of manpower and materials, and affects conventional efficient;So present mathematical probabilities toss a coin (hands throwing pin) experiment Often using computer to be simulated, computer simulation experiment makes student to participate in Probability Experiments, or cannot feel By practical experimentation, thus student cannot be made to deepen the understanding to probability;In consideration of it, be now badly in need of one can make Raw direct feel is to the enjoyment of toss a coin (throwing pin) Probability Experiments, and the mathematical probabilities teaching simulation not affecting conventional efficient sets Standby.
Summary of the invention
In order to make up the deficiencies in the prior art, heretofore described a kind of Pu Feng throw pin experiment mathematical modelling machine and Control system, it can make student's direct feel to throwing the process that coin (throwing pin) is tested, increase student to the interest of probability and reason Solve, and without manual operation, there is higher work efficiency.
