The topic of teacher work satisfaction has long been a focus of educational study. This study examined the impact of school organizational support on teacher job satisfaction as mediated by teachers’ engagement in educational research, utilizing the findings of a survey on the academic quality of basic education students in Jiangsu Province in 2020 and analyzing the data of 21,154 primary and 16,585 secondary school teachers. In this work, the structural equation model is utilized. Significant favorable relationships are shown between school organization support, teachers’ participation in educational research, and teachers’ work happiness. The engagement of teachers in educational research somewhat mediates the relationship between school organization support and teacher job happiness. School organization support positively predicts teacher job satisfaction. The impact of school organization support on teachers’ participation in educational research and job satisfaction is greater at the primary level than at the junior secondary level.

Teacher shortage is a major hindrance to China’s rural education growth in underdeveloped areas, as well as one of the main causes of educational injustice. We conducted a survey of 5,554 teachers from 117 towns in H province in the Wuling Mountains Zone to investigate the issue of rural school teacher supply. From geographical, emotional, and institutional perspectives, we used a polynomial logit model to examine the validity of the “hometown effects” hypothesis. The findings showed that hometown effects exist in China in all three dimensions. The institutional hometown effects are the most pronounced; when compared to open recruitment, teachers sourced through teacher supply augmentation programs (such as the Secondary Normal Graduates Program, Special Position Program, and Targeted Position Program) are more likely to teach in rural schools, particularly more disadvantaged village primary schools or teaching sites. China’s policy of increasing teacher supply has had a considerable positive influence on rural school staffing. Students from rural areas make better teacher candidates; feelings for hometowns should be encouraged among normal school or university students in pre-service education; and the implementation of teacher support policies should be emphasized to retain rural teachers and improve their teaching quality.

Based on the educational hierarchical reproduction theory and the MMI and EMI hypotheses, this paper discusses the impact of the tracking of general and vocational education at the secondary level on higher education opportunity equity among social classes. The study finds that increasing gross enrollment rates of both general high schools and secondary vocational schools can help improve the equity in admission opportunities of colleges and universities among social strata; expanding the share of general high school places by adjusting the structure of general and vocational tracks (that is, the general-vocational ratio) can effectively reduce the class disparities in college and university admission opportunities; neither the change in the scale nor in the structure of general and vocational tracks will contribute to alleviating class inequality in top university enrollment opportunities.

This paper utilizes data from the China Education Panel Survey 2013-2015 to examine the effects of family time and money inputs in education on adolescent academic performance from the perspectives of home social capital, cultural capital, and shadow education. Home time input in education is more vital to teenager academic progress than money input. Domestic social capital and cultural capital as well as weekend shadow education positively impact child academic results. Home-based parental participation as a key component of domestic social capital has the most significant influence on teenager academic improvement, while weekend supplementary tutoring generates the weakest effect; workday extracurricular tutoring even negatively affects student academic achievement. School-based parental involvement differs among families of different classes, with a significant negative effect on academic results of teenagers from disadvantaged backgrounds. Due to the absence of heterogeneity effects of home time input in education on academic progress of students from various social backgrounds, parental time investment should be taken as the most effective means to improve academic performance of adolescents from underprivileged classes.

In recent years, shadow education—paid private supplementary tutoring providing additional educational assistance for students who are preparing for a variety of examinations—has become one of the fastest growing industries in a number of countries around the world, causing concern among governments and education policymakers, who believe that shadow education exacerbates the financial burden on poor families and exacerbates education inequality (Yu & Zhang, 2022).

Leadership behavior of classroom teachers has a significant impact on students’ academic success. However, little empirical research on this subject has been undertaken in China. By developing truth tables and doing necessary computations, this study examines the influence of differential combinations of parameters connected to class teachers’ qualities and leadership behavior on student academic performance. It has been discovered that the democratic leadership behavior displayed by class teachers is the most popular among students and is helpful to student academic achievement; the numerous combinations of linked characteristics have varying effects on student academic performance. The study compensates for a dearth of empirical research on the subject and sheds light on the process by which class teacher leadership influences student academic progress.

Transfer payment is of great significance for poverty alleviation and balanced regional development. Based on the first-hand survey data from 18 key counties of 6 provinces in China’s national poverty alleviation and development program, this paper uses propensity score matching to calculate the effects of transfer payment funds on the results of compulsory education in impoverished areas and uses Shapley value decomposition to decompose correlated factors. It finds that when the characteristics of students, families and schools controlled, transfer payment funds significantly lower student academic achievements in some subjects and aggravate the inequality of educational results, which may be the result of the reduction of local education funds caused by the “crowding out effect” of transfer payment. Suggestions are made in this paper to standardize the utilization of transfer payment funds, establish a linkage mechanism between the educational results of poor students and transfer payment funds, implement the assisting plan for teachers and students in poor areas, strengthen the “pertinent support for intelligence development”, and unite multiple agencies to increase input in education, with the purpose of reducing the inequality of compulsory education in poor areas.

Educational research has long used quantitative and qualitative analysis. Quantitative analysis is the process of quantifying things through the use of numbers, which represent quantifiable characteristics of things such as scale, speed, and degree, as well as the spatial arrangement of their constituents (Yang, 1995). Qualitative analysis is the polar opposite, i.e., evaluating things on the basis of their quality rather than their quantity. A thing's quality refers to its normative nature, which distinguishes it from other things (Li, 1997). Simply put, quantitative analysis focuses on the "what" and employs numerical expressions to depict a given reality, whereas qualitative analysis aims to comprehend the "why" and investigates how we describe something.

Blended instruction integrating off-line and on-line teaching has become an important instrument for promoting educational reform and innovation. However, the results of current empirical studies diverge on the effect of blended instruction on student performance, which necessitates further research on the effectiveness of blended instruction and related factors. This study, using an evidence-based meta-analytical approach, conducts a quantitative analysis of 106 experimental and quasi- experimental studies published from January 2000 to September 2021 in China and abroad, and systematically examines the effectiveness of blended instruction. The research finds that: i) The summary effect size (ES) of the included sample is 0.669 (n=142), indicating that blended instruction has above-moderate positive effects on student performance, especially on student learning motivation and academic emotions and attitude; ii) In terms of education levels, experimental periods and class sizes, blended instruction has the most significant positive effect on junior and senior secondary school students, on a teaching period from one to three months, and on a class size of 51 to 100 students; iii) Regarding the proportion and interactive patterns of online teaching, 50% composition of online teaching and synchronous or synchronous + asynchronous interaction exert the most significant positive effects on student learning. iv) Teaching methods including task-driven learning, role-playing, inquiry-based teaching, and case-based teaching have greater positive effects on student performance than other methods. Group study yields a greater effect on promoting student learning compared to individual study. Based on the findings, the present study also makes suggestions for the effective practice of blended instruction.
