## Abstract

Big data is widely used for its large capacity. Performance appraisal is the evaluation of work, which can serve as a warning and motivation for employees. College teachers play an important role in the development of higher education. How to realize the rational use of college resources is a problem that needs to be solved urgently. This paper aims to study the construction scheme of quantitative assessment of college teachers’ performance based on big data analysis, and use big data analysis methods to make more scientific and reasonable performance assessment methods. Based on the research of relevant theories, this paper analyzes the characteristics and existing problems of the performance appraisal system of college teachers according to the current situation of college teachers’ performance appraisal. In addition, considering the particularity of college teachers, based on questionnaires and field interviews to understand their assessment status and teachers’ expectations for assessment; based on the construction principles of college teachers’ performance assessment system, a college teacher performance assessment system is constructed. The experimental results of this paper show that 140 people believe that performance appraisal is related to salary, accounting for 35% of the total number of teachers. This data shows that the correlation between performance appraisal and salary is relatively high.

## Body

## 1. Introduction

Education directly contributes to the growth of national economy and the advance of S&T, especially the higher education, which provides huge human resources and material wealth to the society. In the process of cultivating talents, teachers in colleges and universities determine to a certain extent whether the school can cultivate outstanding talents. Therefore, how to motivate and spur teachers through quantitative assessment is an important content of college reform. The emergence of the reform and opening-up policy has provided opportunities for the development of China’s economy and technology. In the process of development, data has become an indispensable part of it. This paper aims to study the construction scheme of quantitative assessment of college teachers’ performance based on big data analysis, and use big data analysis methods to make more scientific and reasonable performance assessment methods.Teachers, as an essential part of the tertiary sector, can be fully motivated and motivated if their role is fully exploited, and cultivate more talents. The implementation of performance appraisal facilitates the developmental review of teachers, the growth of their professionalism, and the quality of education.This paper presents an analysis of the proposed system, which has a very good role in promoting the strengthening of the teaching staff of the college. The topic selection is based on the performance assessment of college teachers, and the quantitative assessment is introduced into the assessment of college teachers’ teams, which puts forward new ideas for improving the teacher assessment system. Combined with the characteristics of college teachers’ positions and work characteristics, according to the current situation of college teachers’ performance assessment, a teacher performance assessment index system suitable for the characteristics of colleges and universities is established.


## 2. Related Work

As an important means of enterprise inspection work, performance appraisal is conducive to the scientific development of enterprise work. As a special enterprise in colleges and universities, teachers’ performance appraisal is also very important. AbellT N aims to provide an analysis of the FA practice of chemistry teachers through the lens of the chemistry frame of mind. Two groups of middle and high school science teachers participated in a year-long professional development aimed at enhancing their FA practice in teaching chemistry. To develop a methodology used in ongoing research to analyze teacher progress throughout the year, he provides an analysis of the participants’ final FA portfolio chapters to describe the FA task design, the purpose for which teachers implement FA, and how teachers evaluate students’ work. The experiment revealed a pattern that echoes broader research in science education, but with instantiation in chemistry [1]. The study described by Schafer A assessed item responses by identifying patterns of teacher attention. Results show that comparing the two can reveal potential targets for formative assessment of responses [2]. Deng and Deng studied the results of teaching evaluation of science and technology undergraduates and directed students to pay attention to the main contents of science and technology courses that are highly related to teaching outcomes. Based on factor analysis, he used association rules to obtain high correlations among three factors and found that students studying science and technology courses focused on [3]. The current research on PPDM mainly focuses on how to reduce the privacy risks brought by data mining operations, but actually in data collection, data release, and information (ie, data mining results) delivery. Xu takes a broader perspective on privacy issues related to data mining and studies various methods that help protect sensitive information. For each type of user, he discusses his privacy concerns and the methods he can use to protect sensitive information. He briefly introduces the basics of related research topics, reviews state-of-the-art methods, and presents some preliminary ideas for future research directions [4]. Based on the effect of historical time, Wu classified the samples. To solve the related problems, he integrated the bagging-based ensemble method into back propagation [5].Li envisions these challenges for feature selection in big data analytics. He first introduces feature selection, and then details the structuring problem. Finally, to facilitate and improve the research on feature selection, he proposes an open source feature selection library containing feature selection algorithms [6]. The proliferation of networks of all types has made the types, problems, and problems of big data more varied than ever. Chi Lu reviews the latest research on the types of data associated with Big Data on the Web. He concludes with a summary of Big Data trends and evolutions to anticipate ongoing and upcoming issues [7].While these theories go some way to elaborating on big data and teacher performance appraisal, there is less of a link between the two to achieve meaningful results.

### 3.1. Performance Overview

Performance is a very important part of business management and is a view of how employees are doing as a whole [8, 9]. In practical terms, performance can be divided into a variety of different elements depending on the situation and it can be influenced by the individual employee’s abilities, resulting in different outcomes [10, 11].Performance appraisal is an effective means to check the quality of employees’ work, which is usually measured in years in practice [12]. Through performance appraisal, we can know the actual ability and inadequacy of the staff, and understand the gap with the organizational goal, so as to improve the work and improve the work efficiency [13]. Teacher performance appraisal refers to a series of behavioral evaluations of college staff in the organizational environment of colleges and universities. It includes teachers’ own morality, work attitude, teaching quality, scientific research quantity, etc. Through these evaluations, it is determined whether the teaching staff meet the post standards, so as to promote the enthusiasm of the teaching staff and achieve the organizational goals of the university [14, 15]. In the performance appraisal, teachers should follow the principle of openness to enhance the transparency of the assessment work; the principle of goal consistency, to provide teachers with a guide, so that teachers can give full play to their important role in the work process; the principle of feasibility and practicality.Figure 1 is a schematic diagram of stakeholders.Figure 1
Two-dimensional map of PPP project stakeholders.There are two types of performance appraisals in the organization. Formal appraisals are carried out on a regular basis, with clear rules and clear goals. Informal assessment does not have a specific assessment date, and the purpose is not unique. The common informal assessments include verbal praise and encouragement from supervisors to employees [16, 17]. Performance can exist in many ways. For example, in a PPP project, performance is broken down into two components. For firms, performance is an important indication of profitability. For governments, performance is a method of comparison[18]. The properties intrinsic to PPP items dictate that when conducting performance evaluation, attention should be paid not only to the balance between investment and delivery, but also to the public and utility nature of PPP items.Due to the particularity of the teaching profession in colleges and universities, teachers are different from the performance assessment of other organizations while emphasizing their conduct and performance, and have higher requirements in terms of teaching ability and knowledge reserve [19].The human capital investment of college teachers is larger than that of other industries; the sense of achievement needs of college teachers is strong; the labor objects of college teachers are complex and special; the realization cycle of labor value results of college teachers is long.


### 3.2. Data Mining Technology

Data mining is a method of obtaining information on data resources. It is used in a total variety of ways, driven by IoT technology.Data mining technology finds useful information from massive data and provides decision-making assistance to decision-makers. Introduce data mining technology into the field of performance appraisal, through a variety of data mining techniques, to find out the potential factors that affect teachers’ performance appraisal, so as to provide relevant information for relevant functional departments, promote teachers’ teaching, scientific research and other work to be better carried out, improve teaching and learning. and research service quality.The decision tree is an information analysis tool, which is output in the form of nodes and they represent different information.

## 4. Construction Experiment of Quantitative Assessment of College Teachers’ Performance Based on Big Data Analysis

### 4.1. Data Mining Data

The focus of this paper is the performance evaluation of college teachers. In order to collect the number and basic situation of teachers in colleges and universities, we have investigated the basic situation of teachers in a college in A, the specific situation is as follows:According to the data in Table1, we have investigated the situation of teachers in place A. According to the classification, we have divided teachers into four categories: teaching assistants, lecturers, associate professors and professors, and conducted a comprehensive analysis of teachers with four professional titles. According to the specific data, most of the teaching assistants have master’s degrees, the teaching experience is generally about 4 years, and the average evaluation score is 67. Most of the lecturers have a bachelor’s degree, and their teaching experience is generally about 12 years. The average assessment score is 69. Most of the associate professors have doctoral degrees, and their teaching experience is generally around 29 years. The average assessment score is 88. Most of the professors have master’s degrees, and the teaching experience is generally about 23 years. The average evaluation score is 85. According to the survey data, the evaluation scores of college teachers will increase with the increase of teaching age, which is related to the teaching experience of college teachers.Table 1

In the whole weight division, it is divided into teacher morality, academic qualifications and basic quality. Teachers’ morality accounts for 35%, academic qualifications account for 35%, and teachers’ basic quality accounts for 30%. We have subdivided teachers’ morality, of which ideological style accounts for 33%, moral cultivation accounts for 39%, and collaboration ability among teachers accounts for 15%, teachers’ participation in public welfare activities accounted for 8%, and discipline compliance accounted for 5%. In the education classification, the first degree accounted for 32%, the final degree accounted for 40%, and the further education accounted for 28%. In the basic quality classification, the foreign language level accounts for 30%, the technical application ability accounts for 30%, and the double-qualification situation accounts for 40%. According to the data, it can be seen that teachers’ ideological and moral style and educational background are more important, in addition, teachers’ ability to unite and cooperate is also more important.Table 2

### 4.2. Preparation of Teachers’ Lesson Plans

Lesson plans are the basis of teachers’ teaching, and teachers’ different standards for lesson plan preparation reflect teachers’ different teaching attitudes. In order to explore the teachers in place A, we analyzed the situation of the teachers, the specific situation is as follows:According to the data in Table3, we classified the preparation level of the teaching plan when assessing the teacher’s teaching plan, and divided the teaching plan into four categories: excellent, good, pass, and poor. At the same time, the different components of the lesson plan are subdivided. When the readiness of the components of the lesson plan is less than 0, the comprehensive assessment results are 82, 65, 43 and 16 respectively. When the readiness level of the components of the lesson plan is 0–15, the comprehensive assessment results are 87, 72, 52 and 27 respectively. When the preparation level of the components of the lesson plan is 15–30, the comprehensive assessment results are 91, 78, 63 and 42 respectively. When the preparation level of the components of the lesson plan is 30–60, the comprehensive assessment results are 93, 82, 67 and 55 respectively. When the preparation level of the components of the lesson plan is greater than 60, the comprehensive assessment results are 95, 89, 78 and 65 respectively.Table 3

### 4.3. Attendance Assessment

In addition to students’ attendance assessment, teachers’ attendance is also an important part of the assessment. In order to explore the teachers in place A, we have analyzed the teachers’ attendance. The details are as follows:According to the situation in Table4, we classified the frequency of absenteeism when assessing teachers’ absenteeism, and divided absenteeism into four categories: excellent, good, pass, and poor. At the same time, the frequency of absenteeism was subdivided. When the absences were more than 4 times, the comprehensive assessments were 83, 65, 43 and 13 respectively. When there are 2–4 absences, the comprehensive assessment is 92, 73, 53 and 42 respectively. When the absences were less than 2 times, the comprehensive assessments were 99, 86, 67 and 58 respectively. According to this data, the higher the absenteeism frequency of teachers, the lower the comprehensive examination score.Table 4

## 5. Construction Scheme of Quantitative Assessment of College Teachers’ Performance Based on Big Data Analysis

### 5.1. Current Situation of Teachers in Colleges and Universities

College teachers are an important part of the activities of colleges and universities. In order to evaluate the performance of college teachers, we need to analyze the basic situation of college teachers.According to the data in Figure7, there are 252 full-time teachers in place A, accounting for 63%, and 48 administrative staff, accounting for 12%. There are 36 teaching assistants, accounting for 9%, 16 scientific researchers, accounting for 4%, and 48 other teaching staff, accounting for 12%. According to the data, there are many teaching staff in colleges and universities, of which the proportion of full-time teachers is the highest, and the proportion of scientific research personnel is the least. From this data, it can be seen that there are fewer scientific research talents and more faculty members in colleges and universities.Figure 7
Basic situation analysis of university teachers.Teachers in colleges and universities are an important part of educating students. In order to investigate the age of teachers, we divide them into categories such as less than 28 years old, less than 35 years old, less than 40 years old, less than 55 years old and others. According to the specific data, there are 108 teachers under the age of 28 in place A, accounting for 27%, and 88 teachers under the age of 35, accounting for 22%. There are 76 teachers younger than 40 years old, accounting for 19%, 16 teachers younger than 55 years old, accounting for 6%, and 68 teachers older than 55 years old, accounting for 17%. According to the data, with the continuous development of the teaching team, more and more young people have joined the teaching team, which will inject fresh blood into the entire teaching team.According to the data in Figure8, in order to understand the teaching status of college employees, we investigated the teachers’ professional titles in place A. Among them, there are 48 senior teachers, 12% of instructors, 132 associate senior teachers (33% of instructors). There were 160 intermediate teachers, 40% of faculty, 44 junior teachers, 11% of faculty, and 16 teachers without a title, 4% of faculty. Based on the information, the proportion of intermediate teachers is the highest, and the number of senior and junior titles is less.Figure 8
Distribution of university teachers’ education.In addition to the survey of the professional titles of college teachers, we also surveyed the academic qualifications of teachers. Among them, 56 have doctoral degrees, 14% of faculty, 140 have a master’s degree, 35% of faculty. 192 teachers have a bachelor’s degree, 48% of faculty, and 12 have a college degree or less, 3% of faculty members. The data shows that the highest percentage of teachers have a bachelor’s degree, including more middle-aged teachers, which can promote the further study of in-service teachers. The proportion of teachers with a junior college or below is the lowest, indicating that college teachers have higher and higher requirements for academic qualifications, which also shows that the overall academic qualifications of the entire industry have generally increased.


### 5.2. Impact of Performance Appraisal

Performance appraisal can not only check the work situation of employees, but also motivate employees, but if performance appraisal is not scientific, it may also have the opposite effect.According to the data in Figure9, we have analyzed the assessments implemented in colleges and universities and conducted interviews with local teachers. Among them, 140 think that performance appraisal is related to salary, 35% of judges, 120 (30% of teachers) thought that performance appraisal was related to promotion. One hundred and twelve thought that performance appraisal was related to employment, 28% of instructors, and 28 were unclear about the factors influencing performance appraisal, 5% of instructors. The data show that in those universities where the appointment system for university teachers is in place, there is no focus on linking the results of performance appraisals to the appointment of teachers, which is an appointment system that does not live up to its name. However, according to survey research, not all performance appraisals have a clear purpose.Figure 9
Performance appraisal impact analysis.In addition to the influencing factors of performance appraisal, we also investigated which factors are related to teachers’ expectation of performance appraisal results. According to the survey data, 136 teachers expect the assessment results to be related to their salary, 34% of instructors, 124 instructors, or 31% of instructors, expected assessment results to be related to promotion. One hundred and twenty teachers, or 30% of instructors, expected assessment results to be related to appointment, and twenty teachers, or 5% of instructors, had no clear requirements for assessment or promotion. Based on the data, performance appraisal needs to combine the strategic positioning of different universities and the management of teachers to formulate a performance appraisal system that conforms to their own development.


### 5.3. The Role of Teacher Performance Appraisal

According to the data in Figure10, in order to investigate the role of performance appraisal in colleges and universities, we surveyed teachers in local colleges and universities. Among them, 152 people think that performance appraisal will mobilize the enthusiasm of teachers, accounting for 38%. There are 96 people believe that performance appraisal will introduce external competition, lead to internal elimination, and improve the local teaching level of teachers, accounting for 24%. There are 108 people believe that performance appraisal will stimulate the personnel mechanism in colleges and universities, accounting for 27%, and 44 people think that performance appraisal can better complete supervision and management, accounting for 11%. According to the data, in the whole performance effect, mobilizing teachers’ enthusiasm accounts for the highest proportion, indicating that the motivational effect of performance analysis is very obvious.Figure 10
Analysis of the role of teacher performance appraisal.According to the current performance appraisal situation, 244 people believe that the current appraisal system needs to be rectified, accounting for 61%. There are 100 people think that the current assessment system is very general, accounting for 25%. There are 20 people think that the current appraisal system does not need to be rectified, accounting for 5%, and 36 people have no opinion on the current performance appraisal system, accounting for 9%. According to the data, most employees in colleges and universities believe that the current performance appraisal system needs to be rectified.


## 5.1. Current Situation of Teachers in Colleges and Universities

College teachers are an important part of the activities of colleges and universities. In order to evaluate the performance of college teachers, we need to analyze the basic situation of college teachers.According to the data in Figure7, there are 252 full-time teachers in place A, accounting for 63%, and 48 administrative staff, accounting for 12%. There are 36 teaching assistants, accounting for 9%, 16 scientific researchers, accounting for 4%, and 48 other teaching staff, accounting for 12%. According to the data, there are many teaching staff in colleges and universities, of which the proportion of full-time teachers is the highest, and the proportion of scientific research personnel is the least. From this data, it can be seen that there are fewer scientific research talents and more faculty members in colleges and universities.Figure 7
Basic situation analysis of university teachers.Teachers in colleges and universities are an important part of educating students. In order to investigate the age of teachers, we divide them into categories such as less than 28 years old, less than 35 years old, less than 40 years old, less than 55 years old and others. According to the specific data, there are 108 teachers under the age of 28 in place A, accounting for 27%, and 88 teachers under the age of 35, accounting for 22%. There are 76 teachers younger than 40 years old, accounting for 19%, 16 teachers younger than 55 years old, accounting for 6%, and 68 teachers older than 55 years old, accounting for 17%. According to the data, with the continuous development of the teaching team, more and more young people have joined the teaching team, which will inject fresh blood into the entire teaching team.According to the data in Figure8, in order to understand the teaching status of college employees, we investigated the teachers’ professional titles in place A. Among them, there are 48 senior teachers, 12% of instructors, 132 associate senior teachers (33% of instructors). There were 160 intermediate teachers, 40% of faculty, 44 junior teachers, 11% of faculty, and 16 teachers without a title, 4% of faculty. Based on the information, the proportion of intermediate teachers is the highest, and the number of senior and junior titles is less.Figure 8

Among them, 56 have doctoral degrees, 14% of faculty, 140 have a master’s degree, 35% of faculty. 192 teachers have a bachelor’s degree, 48% of faculty, and 12 have a college degree or less, 3% of faculty members.

## 6. Conclusions

The problem of cultivating engineering talents in the 21st century is a key issue in the industrial development and international competition of various countries. With the development of the socialist economy with Chinese characteristics, the current society pays more and more attention to the quality of education, and teachers, as an important part of colleges and universities, are of great significance to the education of students. This paper aims to study the construction scheme of quantitative assessment of college teachers’ performance based on big data analysis, and use big data analysis methods to make more scientific and reasonable performance assessment methods. Although this paper explores the performance appraisal of college teachers, there are still some shortcomings: (1) Colleges and universities are in the process of continuous development and improvement, and talent management should also be constantly transformed, which is not mentioned in this part of the article. (2) How to improve teachers’ own moral construction and make moral construction and system construction develop together is difficult in practice.
