        <p>In the article the expediency of quality assessment of teaching the disciplines in higher education institutions was justified. A method of quality assessment level of teaching the disciplines and respective algorithm were proposed for making informed decisions in the quality management of education. This method is based on using the expert method of paired comparison and identifies two common forms of control: control at the level of teacher to learn the experience of colleagues (reciprocal visits) and a survey of students after studying disciplines. The paper concentrates on the correlation between indexes of teaching quality renders possible to quantify the overall index, which is called "level of teaching quality". Furthermore, the method takes into account the requirement of quality management systems to identify critical points and eliminate inconsistencies.</p>

      <p>Rapid changes in the political, socio-economic and cultural realities in Ukraine and
abroad, the current trends of globalization and integration of the world community have
an impact on education. The modernization in education requires the use of innovative
technologies, creative search of new strategic directions for content improving,
methods, techniques and means of education and their application in the educational process
of higher education institutions.</p>
      <p>
        Higher education institutions begin to develop the quality management system at this
current stage of development of higher education in Ukraine, that meet the requirements
of ДСТУ ISO 9001:2015 (harmonized with ISO 9001:2015) [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ] and include not only
the organization of the educational process, but also technical, financial and other
material and methodological resources. In this connection, acutely raised the question
about the teaching quality of discipline that affects the activation of students' knowledge
and their positive motivation.
      </p>
      <p>In addition, significantly increases the role of modern information technology, namely
the use of a single computer learning environment. This renders possible a systematic
approach to raising the level of educational services within higher education
institutions.</p>
      <p>Therefore, raising the quality of educational services by application the assessment
system of teaching subjects in a single information space is an important issue for higher
education institutions.

      <p>
        The Application Relevance of Quality Assessment System of
Teaching the Disciplines
Today higher education in Ukraine is in the process of transformation from the Soviet
to the European model, established in accordance with the signed by Ukraine in 2002
Bologna agreement. By joining the Bologna process, Ukraine has pledged to work on
bringing the quality of national education in line with European standards.
The main focus in reforming of higher education made on the need to create the internal
quality systems. One of the main tasks of quality management systems according to the
standards requirements of ISO 9001:2015, which are implemented in modern
universities, is the presence of the feedback and determines the satisfaction degree of internal
customers – students. The education quality or obtaining specialists, which are required
by employers, primarily dependent on the quality of teacher’s work [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ]. So, the issue
of control and assessment of the teacher’s work quality is one of the difficult and
important tasks in management of the education quality. Such assessment is necessary to
correct actions in the educational processes and for changes to the organization
management, educational programs and technology education, as well as joining the
Bologna process, which requires accreditation of individual disciplines of the curriculum.
The main principles of creation of feedback systems involved in a number of scientists:
С. Evans [
        <xref ref-type="bibr" rid="ref3">3</xref>
        ]; A. Lizzio and K. Wilson [
        <xref ref-type="bibr" rid="ref4">4</xref>
        ]; E.C. Ball [
        <xref ref-type="bibr" rid="ref5">5</xref>
        ]; P. Black and D. William [
        <xref ref-type="bibr" rid="ref6">6</xref>
        ];
J. Hattie and H. Timperley [
        <xref ref-type="bibr" rid="ref7">7</xref>
        ] etc. Their research focused on the study of the influence
of these systems on the motivation of students (and thus the education quality at all).
The study of feedback is not new in Ukraine. For example, in Kherson State University
under the guidance of Professor Spivakovsky O.V. the information system of
satisfaction assessment of students, based on the use of KSU Feedback service, was organized
[
        <xref ref-type="bibr" rid="ref8 ref9">8,9</xref>
        ].
      </p>
      <p>Analyzing the results and making decisions, based on them, is no less important stage
of assessment quality of teaching the disciplines.</p>
      <p>To ensure the quality of higher education have approved a number of normative
documents in Ukraine such as [10,11]. They identified the main ways to improve the
education quality and responsible departments.</p>
      <p>In Sumy State University (SSU) the number of normative documents such as:
Regulation "About the quality control system of the educational process in SSU", Regulation
"About bureau of quality assurance of education and quality of higher education" and
others were introduced [12,13,14,15]. These documents regulate the organizational
forms and components of the quality control system of the educational process,
monitoring the quality of educational activity and quality of higher education at all in its
various components throughout the university. Also, the Council on ensuring the
quality of educational activity and the quality of higher education was established at the
university, which implements the university policy in the field of quality assurance and
monitoring. Moreover, since 2015 the EU project Erasmus+ “Quality Assurance system
in Ukraine: Development on the Base of ENQA Standards and Guidelines”
(QUARE562013-EPP-1-2015-1-PL-EPPKA2-CBHE-SP) has been implementing in the SSU in
cooperation with leading universities in Ukraine with the support of the Ministry of
Education and Science of Ukraine.</p>
      <p>But the analysis of requirements of normative documents of Ukraine and SSU has
demonstrated that the criterias and methods of evaluating the quality of teaching are not
identified, therefore the authors propose the development of a system and method of
assessment of indexes of teaching quality.</p>
      <p>It should be noted that nowadays the educational process is characterized by the
introduction of modern information systems, which is to create single information space
[16]. This greatly simplifies the exchange of information and data collection. In
addition, IT renders possible create large amounts of the original data and analyze it as soon
as possible.</p>
      <p>SSU implemented a system of e-learning [17], which operates in a single information
space of the university and consists of subsystems: storage and access to teaching
materials; management of educational process; providing the development and filling of
educational content; interaction of participants of the educational process and student’s
electronic office. All subsystems are closely integrated with each other and work
together in a single system.</p>
      <p>So, the development of an assessment system of the quality of teaching the disciplines
should be carried out with capabilities and requirements of information systems, which
are implemented at the university.

      <p>Development of Assessment Method of Teaching Quality
Indexes
Analysis of national experience in the quality assessing of teaching the disciplines
renders possible to identify two common forms of control: control at the level of teacher
conducted to learn the experience of colleagues (reciprocal visits) and a survey of
students at certain intervals of time or after studying particular disciplines.
As already noted, the assessment criterias of the quality of the teacher of university are
not defined normative. Therefore, in educational institutions there are different lists of
requirements for teachers. Typically, they are used in the procedure of competitive
selection for vacancies and assessment of these indexes is subjective and linguistic, for
example "good" or "satisfactory".</p>
      <p>To make decisions about the quality of teaching the disciplines it was proposed an
overall index, which is called "level of quality". We should have an opportunity to evaluate
it quantitatively for the proving our decisions. Therefore, the system of indexes of
teaching quality was proposed (Fig. 1).</p>

For the assessing of the "level of teaching quality" of disciplines at the universities a
comprehensive index of teaching quality is proposed, which is calculated according to
the formula [18,19,20]:</p>

where Qi – value of unit quality index in classification group (in scores);
n – number of indexes of teaching quality.</p>
      <p>For clary presentation of the complex index, its value is normalized to a standard that
has a value of 100%. Also has used a conversion factor of dimension – 100/9, as the
maximum value of a single index of teaching quality that is equal to 9 scores.
The assessment process is recommended to use according to the algorithm that is shown
in Fig. 2.</p>
      <p>In Fig. 2 the value of individual index of teaching quality is obtained through students
in a questionnaire in the electronic office (block 3) or interviews with experts, teachers
during reciprocal visits (block 4). To quantitative (scoring) characteristics of individual
index of quality teaching Qi usually used scale, which is given in Table 1.
Authors propose to substantiate values of the weighting coefficients of the index of
teaching quality by carring out of using expert method of paired comparison – a set of
logical, mathematical and statistical methods and procedures which related to the
expert’s activities on processing information that is necessary for analysis and decision
making.</p>
      <p>The procedure for determining the weighting coefficients consists of two stages: the
first stage is the selection of the optimal set of X features, the second is the set of
numerical values of each feature X.</p>
      <p>The coding factors and determination of expert’s opinion are carried out after work on
the formation of the expert group. Results of analysis the opinions sheet of the member
of expert group is given in the Table 2.</p>

The clarification of weighting coefficients in this work is proposed to realize by the
method of successive approximation. In a Table 2 the values of weighting coefficients
obtained by double paired comparison method of successive approximation, in which
the result of measurement in the (w) approach is defined as the weighted mean. Initial
results are considered in this case as a first approximation.

      <p>The second approach used as weighting coefficients γj(2) of experts opinions. Obtaining
the new results with these weighting coefficients, in the third approach are considered
again as the weighting coefficients γj(3) of the same expert opinion, etc. According to
Theorem Peron-Frobenius [21], in particular conditions, this process converges, i.e
weighting coefficients tend to some constant values that reflect the relationship between

      <p>The result of measurement of the j-th index in the first approximation Gj(1) (original
result) determined by the formula:</p>
      <p>m

where Kjl - number of benefits of index j by one expert (l=1…m );
Measurements of j-th index in (w) approaching equal [22]:</p>
      <p>G j (w) </p>
      <p>[(G1(w  1)]2  K j1  ...  [(Gm (w  1)]2  K jm ,
where Gj(w-1) – outcome measurement of j index in a (w-1) approximation.

 j (w)  m

Values clarification process as long as the accuracy will not match the specified one, in
other words, until reaching the condition:
where  – given the accuracy of calculations, which is accepted [20]:
 j (w)  j (w 1)   ,
  0, 001 при 1  a  1; ,
  0, 01 при a  5

where a – coefficient that shows: how many times the weighting of the best index
exceeds the weighting of the worst index.</p>
      <p>For the coefficient assessment of consistency of expert opinion, usually use the Kendal
coefficient of concordance [22]. Consistency of expert opinions is considered as
acceptable if the value of the coefficient of concordance W  0, 6 .</p>
      <p>Summary table of weighting coefficients of indexes of teaching quality is the result of
expert assessments (Table 3).
The scale of desirability Harington is used for the formalization of complex quality
index [23]. It refers to scales that are in the interval from zero to one. Therefore, for
decision-making, based on comprehensive assessment "level of teaching quality", are
offered the following recommendations (Table 4).

      <p>Practical Implementation of the Method of Assessment
Teaching Quality
The proposed in chapter 2 algorithm considers two forms of control: control at the level
of teacher (reciprocal visits) and a survey of students at certain intervals of time or after
studying particular disciplines.</p>
      <p>Requirements for the first form of control are presented in SSU normative documents
[12,13,14,15]. According to the requirements of these Regulations SSU introduced
reciprocal visits. Annually forming composition of expert groups and schedule of visits
to classes.</p>
      <p>Recommendations for decision-making
Very good quality. The process of teaching complies with all
requirements; quality ensured.</p>
      <p>Good quality. A minor mismatch. The process of teaching may
be acceptable subject to the implementation of corrective action;
there are insignificant inconsistencies (or one big inconsistency)
Satisfactory quality. Much discrepancy. The process of teaching
is satisfactory and can be conditionally enlisted; there are
significant inconsistencies that shoul be eliminated. The process
requires the development of analysis and eliminating of
inconsistencies (or development of plan for corrective actions).</p>
      <p>Bad quality. Critical discrepancy of teaching process. The
process requires a time limit to eliminate inconsistencies.</p>
      <p>Very poor quality. Complete mismatch. The process requires the
development of a plan of corrective action, and time limit to
removing inconsistencies and re-inspection.</p>
      <p>However, the quality of teaching is not sufficiently appreciated without taking into
account feedback from the students. The survey can be conducted through questionnaires
or in the electronic office. SSU currently being tested "electronic personal office" – a
single window access to various information services that will enable easy and timely
receive customized information on training.</p>
      <p>Practical implementation of the the proposed model of teaching quality assessment was
conducted by the example of teachers of the department of Manufacturing Engineering,
Machines and Tools. There were 32 students in specialty "Manufacturing Engineering"
(level of Master of Science degree) on the five core disciplines teachers. The results
data are summarized in Table 5.
The teacher presence in the "satisfactory quality" explains his lack of experience
teaching (first year after graduate school) and teaching a new course for the new curriculum.
During the evaluation revealed the following critical points: the interconnection of
material with professional interests and insufficient use of technical training aids.</p>
      <p>Conclusions
The work presents the research that aimed at improving the process of assessment of
teaching quality at the universities, namely the current situation and ways of
improvement of the teaching process were analyzed. The analysis of normative documents in
field of education has shown the lack of a broad research of the question of assessing
of teaching quality and the lack of uniform system of indexes of teaching quality.
Therefore, as the result of research the overall index of teaching quality, the system of
component indexes of quality and the method for its assessment in teaching the
disciplines were proposed. In addition, the recommendations for decision-making based on
the level of teaching quality were developed.</p>
      <p>The application of the proposed method of assessment the teaching quality in
universities in practice renders possible to:
· on the basis of quantitative evaluation to carry out an objective assessment of the
level of teaching quality at the universities;
· make informed decisions in the quality management of educational process;
· identify discrepancies (critical points) and criterias for developing a plan of
corrective actions.</p>
      <p>In the nearest future it is planned to improve normative base of higher education
institutions through the development of a normative document, in which the requirements
for teaching quality will be regulated and the method and nomenclature of indexes of
assessment the teaching quality at higher education institutions will be presented.
