Ways to Improve the Quality of Higher Education by Studying Perceptions of the Teachers

: In this paper the author analyzes empirically the perception of teaching staff in technical higher education regarding the quality of university education services. The research was conducted online and the respondents were the teaching staff in University POLITEHNICA of Bucharest, the largest technical university in Romania. The tool used was the questionnaire consisting of closed and open questions that allowed in-depth data collection. Teachers have provided some suggestions for improving the quality of educational services among which: reducing the number of students in the groups, modifying the curriculum and content of the disciplines where appropriate and involving master students in research activities.


Introduction
Quality is the ability of a bidder to produce/assure the characteristics of goods or services at a certain level determined on the basis of customer expectations [Bruhn, 2001].Especially, the quality in technical higher education is primarily related to the quality of the human resource [Manea, 2015[Manea, , 2017)); Manea et al, 2017].When talking about the quality of an educational service, both the provider (the teacher) and the beneficiary (the student) participate in its realization.The quality of higher education services is an important objective that can increase economic efficiency [Kang, James, 2004;Seth et al., 2005].The perceived quality of service is a component of customer satisfaction [Zeithaml et al., 2013].tool used was the questionnaire, which contained 20 closed, open, dichotomous and multihomous questions.In order to study the perception the previous experience in the university is needed, so teachers with a minimum of 2 years of experience in UPB have been considered.

Research objectives
1. Identifying teachers' perception about the working 2. Identifying teachers' perception about the UPB's salary package.
3. Identifying teachers' perception regarding the quality of teaching in UPB.

Research hypothesis
1. Most employees (over 51%) 2. The majority of teachers (over 51%) are satisfied with the salary package.
3. Teachers in UPB believe that the teachingis a quality one, but there is always room for improvement.

Data analysis
In order to identify teachers' perception about the working environment in UPB we need to know their seniority within the university

Figure
As can be seen, most of the respondents have a seniority within the university years (43%).
In order to identify perceptions regarding the working environment of UPB, several variables were taken into account, namely: teamwork (Figure 2), relationship with the direct hierarchical superior (Figure 3) as well as opportunities and professional promotion.(Figure 4).In order to study the perception the previous experience in the university is needed, so teachers with a minimum of 2 years of experience in UPB have 1.Identifying teachers' perception about the working environment in UPB.

The data analysis in the above figures shows that the perception of respondents about the working environment in UPB is also a small percentage of "Most employees (over 51%) perceive Only basic salary and related bonuses of the respondents was taken into account, not the income (which for most employees are higher due to scientific research projects).Thus, the hypothesis according to which " salary package" is infirmed.analysis in the above figures shows that the perception of respondents about the working environment in UPB is generally favorable or very favorable, although there are a small percentage of dissatisfied respondents.This confirms the hypothesis Most employees (over 51%) perceive favorable the working environment

In order to achieve the third objective of the paper (Identification of teacher perception regarding the quality of teaching in UPB), open questions were used to allow respondents to express themselves freely.Table 1 summarizes their responses.-Interested in knowing, smart, determined -Intuition, creativity, intelligence, sense of humor, ability to analyze and synthesize -Open to new, eager to acquire knowledge, adaptable -To be altruistic, energetic, sociable, willing to experience If you consider it necessary, please provide some suggestions for improving the quality of educational services in UPB -Reducing the number of students in groups -Modifying the curriculum and the content of the discipline in accordance with the requirements of the labor market -Involving students in research activities -Developing entrepreneurship -Attracting foreign students to Erasmus exchanges and masters programs -Well-trained teachers who prove their vocation for the tutoring profession -Reduce the number of hours in the baseline and limit the number of hours spent in hourly payment -Developing the practical nature of disciplines, real case studies -I do not consider it necessary As can be seen from the above table, the teachers perceive favorable the teaching in UPB, although some respondents considered it necessary to offer some suggestions for improving the quality of the educational services, thus confirming the last hypothesis (Teachers in UPB believe that the teachingis a quality one, but there is always room for improvement).

Conclusion
The data analysis from this research shows that the perception of the respondents regarding the working environment of UPB is favorable or very favorable one.Although there are also dissatisfied respondents, their percentage is small.Also, with regard to the UPB's wage package, we can see that only 38.8% of respondents are satisfied with it, 30% of them are neutral, while 21% are dissatisfied.Percentages may mean that those who considered the answer to the question neutral have other sources of income (scientific research projects, consultancy, hourly payment) also.
The quality of the teaching is a priority for the respondents, so they considered it necessary to offer suggestions for improvement.They also suggested ways to attract students by developing the practical nature of disciplines and by developing entrepreneurship.
The limits of the research derive from the size of sample (small), unrepresentative in order to be generalized at the level of all the teaching staff of UPB.
Although it is an empirical research, this study can provide sufficient information for a further in-depth research.
