摘 要

本文通過建立數(shù)學(xué)模型對教學(xué)質(zhì)量進行評估,應(yīng)用馬爾科夫鏈分析法考慮學(xué)生的原始狀態(tài),在同一標(biāo)準(zhǔn)下把 、 教師學(xué)生的初始成績分成五個等級,確定出狀態(tài)空間,然后根據(jù)施教后的成績,求出一步轉(zhuǎn)移概率,建立一步轉(zhuǎn)移概率矩陣,最后根據(jù)馬爾科夫鏈的遍歷性求出極限分布 .對每一等級賦予分?jǐn)?shù),對教學(xué)效果的定量指標(biāo)加權(quán)平均,由所得的數(shù)學(xué)期望來評價教師的教學(xué)質(zhì)量,這種方法克服了學(xué)生原有基礎(chǔ)存在差異的問題.轉(zhuǎn)移概率矩陣 集中反映了教學(xué)質(zhì)量、教學(xué)條件、學(xué)風(fēng)及社會環(huán)境等等因素的影響, 的極限狀態(tài)說明,這些因素穩(wěn)定時,教學(xué)效果在這些條件的影響下可能達到的程度,且這一可能達到的程度與學(xué)生原有的基礎(chǔ)無關(guān).由極限分布 可以對極限狀態(tài)下各等級人數(shù)進行預(yù)測,通過分析使教師獲取教學(xué)的反饋信息,以對自己的教學(xué)方式進行反思和調(diào)整,促進教學(xué)水平的提高.
對馬氏鏈模型進行改進,在求得一步轉(zhuǎn)移概率矩陣后,定義學(xué)生成績“進步度”,即學(xué)生進步的程度(退步時進步度為負(fù)值),把握學(xué)生成績的整體進步、退步情況,同時也消除了基礎(chǔ)差異的因素.通過計算進步矩陣和效率值又能對教學(xué)效果進行評價,且與馬氏鏈模型所得的結(jié)論一致,同時還能得到一些很有參考價值的教學(xué)反饋信息.

ABSTRACT

In this thesis, we study a mathematical model which can eva luate the quality of teaching. We analysis the original state of the student by Markov chain, In the same standard, we divided the students who tought by teacher A and teacher B respectively into five levels by initial achievement, then determine the state space. We calculate the one step Transition probability matrix according to the student’s achievement that after teaching, and obtain the Limit distribution by Markov chain Ergodicity. The quantitative index of teaching weighted average by given every level scores, so we can eva luate the teaching quality according to the mathematical expectation. This method overcome the problem of student’s basis difference, therefore, Transition probability matrix reflects the quality of teaching, teaching conditions, style of study and social environment, and so on. Limit distribution shows teaching effectiveness may reach when these factors are stable, and it have nothing to do with the students’ basis difference. By analyzing the feedback information, teachers can adjust their teaching style, and improve the teaching quality.
To improve the Markov chain model, we define ‘progress degree’,which is the extent of the student progress (the progress degree is negative when regress). From the progress degree we can learn the overall progress of students achievement, and it also eliminates the factor of basis difference. We can eva luate the teaching quality by calculate the progress matrix and the value of efficiency, and it’s conclusion is similar to the model of Markov chain, we can also get some valuable feedback information.
Keywords: Markov chain; Transition probability matrix; Ergodicity; Teaching eva luation; Limit distribution
