## Description

[0001] 本发明涉及数学教具领域，具体的说是一种掷币实验用数学概率运算设备及其控制系统。 [0001] The present invention relates to the field of mathematics teaching aids, specifically a coin toss experiment mathematical probability calculation apparatus and a control system.

[0002] 概率，又称或然率、机会率、机率(几率)或可能性，它是概率论的基本概念。 [0002] probability, also known as probability, chance of probability (chance) or the possibility that it is the basic concept of probability theory. 概率是对随机事件发生的可能性的度量，一般以一个在〇到1之间的实数表示一个事件发生的可能性大小。 Probability is a measure of the likelihood of random events, and generally in a square to a real number between 1 indicates the likelihood of a magnitude events. 越接近1，该事件更可能发生;越接近〇，则该事件更不可能发生，其是客观论证，而非主观验证。 The closer to 1, the event is more likely to occur; the closer billion, the event is more likely to occur, it is an objective verification, rather than subjective validation.

[0003] 概率实验一般包括摸球游戏，掷硬币，转转盘，投针试验，掷图钉和掷瓶盖等实验， 上述实验都应该让学生亲身做，这些实验比较简单，实验结果也不复杂，可操作性强。 [0003] probability experiments typically include touch the ball game, a coin toss, the jog dial, cast needle test, throw and throw pushpin caps and other experiments, the above experiment should allow students to personally do these experiments is relatively simple, not complicated results , strong operability. 通过亲身做可以更好的体会事件发生的频率，及频率与概率的联系与区别，体会大量重复实验时频率可以作为事件发生概率的估计值。 By doing personally frequency can better understand events, and contact with the difference frequency and probability, when a lot of experience experiment was repeated frequency can be used as an estimate of the probability of occurrence of the event.

[0004] 学生亲自做掷硬币实验有以下几个作用： [0004] student personally do a coin toss experiment has the following effects:

[0005] 1.有助于学生体会随机现象的特点。 [0005] 1 helps students to understand the characteristics of random phenomena. 在进行试验及对试验数据的分析中，学生将逐渐体会到随机现象的不确定性，以及大量重复试验所呈现的规律性。 Conducting tests and analysis of the test data, students will come to realize the uncertainty of random phenomena, as well as a large number of repeated trials presented regularity.

[0006] 2.通过概率实验，有助于学生澄清一些错误认识。 [0006] 2. probability experiments to help students clarify some misconceptions. 通过亲自做实验，学生可以在实验的过程当中去体会事情发生的不确定性;对于那些还存在的困惑，尤其是与经验不符的结果，通过实验，澄清错误认识，让学生信服。 By personally doing the experiment, students can experiment and understand the process of the uncertainty of what happened; for those confused there, especially with the experience inconsistent results, experiments, clarify misconceptions, to enable students to be convinced.

[0007] 现有的人工掷硬币实验往往是通过一人手抛硬币，另一人旁边计数的方式进行实验，然而，由于需要实验的次数之多，因而上述掷硬币概率实验的方法需要耗费大量人力物力，且影响实验效率;所以现在的数学概率掷硬币实验往往采用计算机进行模拟，计算机模拟实验使得学生无法参与到概率实验中，或者无法感受到切实的实验过程，从而无法使得学生加深对概率的理解;鉴于此，现急需一种能够使学生直观感受到掷硬币概率实验的乐趣，并且不影响实验效率的数学概率掷币设备。 [0007] Existing artificial coin toss experiment often experiment with a coin toss hand, another person next counting mode, however, since the number of experiments needed much, whereby said coin toss experiment probabilistic method requires a lot of manpower and the effects of experimental efficiency; so now mathematical probability of a coin toss experiment often using computer simulation, computer simulation so that the student can not participate in the probability experiment, or can not feel real experiment, and thus can not allow students to deepen understanding of the probability of ; in view of this, the students are now in urgent need of a solution that provides an intuitive feel pleasure coin toss probability experiment, and does not affect the efficiency of the experimental mathematical probability toss equipment.

[0008] 为了弥补现有技术的不足，本发明中所述的一种掷币实验用数学概率运算设备， 其能够使学生直观感受到掷币实验的过程，增加学生对概率的兴趣和理解，且无需人工操作，具有较高的工作效率。 [0008] In order to compensate for deficiencies of the prior art A coin toss experiment according to the present invention in mathematical probability calculation device, which enables students to feel an intuitive process toss experiment, increase student interest and understanding of the probability, and without manual operation, with high efficiency.
