Teachers ’ Professional Development Needs and the Systems That Meet Them

The purpose of this study was to identify professional development needs of primary and secondary school teachers and to present their views on the systems that meet those needs. The research model utilized in the study was the mixed model type. Findings related to identification of teachers’ professional development needs were collected through quantitative methods whereas findings related to systems that meet those needs were collected qualitatively. The study utilized survey model since it identified teachers’ professional development needs and investigated the systems that meet those needs. The part of the study related to identification of teachers’ professional development needs was quantitative and the section that investigated the systems that met professional development needs was qualitative. Data regarding the quantitative part of the study was collected with a data collection tool composed of 34 items prepared by the researcher and the data regarding the qualitative part of the study was collected, a 5-item data collection tool prepared by the researcher. Working group was composed of a total of 207 teachers selected via “simple random sampling” from the universe. Results showed that teachers needed development in the following areas mostly: “extracurricular and classroom activities”, “instructional programs and evaluation”, “teacher-student relationships” and “organization of instructional environments”. Teacher stated that they met their professional development needs in the following order from the most to least: through own individual studies, social learning among colleagues, in-service training, school administration and educational inspection.


Introduction
It is thought that pre-service training provided by teachers is not sufficient to effectively undertake the services they provide.Changes in education and school systems, globalization and transformation process, renewal of instructional programs, advances in educational technologies, different expectations of the environment and labor market from schools, impact of economic and political systems and increased discipline problems related to students are among the variables that necessitate teachers to develop and renew themselves.All these variables require that teachers should be provided with professional development opportunities.
Five systems that meet teachers' professional development needs can be cited: inspection units whose main job descriptions include providing guidance and on-the-job training activities to educational staff, school administrations that prioritize teachers' educational leadership roles, local and central in-service training programs, social learning among colleagues and teachers' personal studies.

Educational Inspection
While traditional organization and management theories consider inspection as the process of controlling human behavior, modern organization and management theories define inspection as the guidance and on-the-job training activities to develop professional competences of staff.Inspection systems exist in all complex systems and they are organizational and administrative obligations (Aydın, 1993).Inspection is an indispensable process in social activities in which human element is especially dominant (Cengiz, 1998).Importance of inspection will be better comprehended when structure of organizations, management processes and systems theory are examined (Taymaz, 1997).Imperative nature of inspection is a natural result of the organization's determination to sustain itself (Aydın, 1993).Başaran (1996) who regards inspection as one of the sub processes of administration states that it is universal and no organization can work without inspection regardless of its type, purpose or establishment.
Inspection adapted to education and training is defined as educational inspection."In this context, all inspection activities organized and implemented in educational institutions should be defined and named as educational inspection" (Başaran, Bozkurt, Karabıyık, 2003).Inspection is an element of administration process and therefore an element of the school management.It helps obtaining the degree of realization in pre-determined education and training goals (Bursalıoğlu, 1994).Rapidly changing requests about schools in order to increase productivity and quality in education have increased the importance given to inspection in recent years (Seçkin, 1991: p. 202).
Educational inspection is defined as the process that include all of the following: identifying the degree of realization in established organizational purposes, monitoring and correcting the operations of the organization, controlling staff behaviors and providing guidance and counseling services to teachers and other personnel (Aydın, 1993, Başaran, 1996, Bursalıoğlu,1994, Dağlı, 2003, Kaya, 1986, Taymaz, 1993).As a sub system of education, inspection aims to identify and improve the degree of implementation regarding educational goals (Gökçe, 2004).Goals of the organization are better comprehended through inspection, procedures are followed and necessary precautions are taken when goals are not met (Seçkin, 1991).Inspection has an essential function and value in all organizational systems in general and in education and school systems in particular (Aslan, 1999).The modern approaches to educational inspection consist of inspection approaches that center around guidance and on-the-job training and that aim to provide self-control skills.It is necessary to meet teachers' professional development needs at schools through inspection.

School Administration
Today, school administrators are expected to lead teachers and students.Many of the authors in the field of management define leadership as a process of guiding and affecting human efforts to reach specific aims (Hodgetts, 1999).In the most general sense, leadership is a social process that affects group members' interpretation of internal and external events, goal selection, activity organization, individual motivation and skills, power relationships and common aspects (Hoy and Miskel, 2010).
Various leadership styles have emerged due to advances in organizational and administrative sciences, emerging complexities in organizations and diversifications in societal expectations from organizations.Dominant leadership style in educational organizations is reflected as instructional leadership style.Instructional leadership consists of defining the school mission, managing the instructional program and teaching and developing a positive learning climate dimensions (Hallinger and Murphy, 1985).Instructional leadership was developed in line with school Administration and it is a leadership style that focuses on teaching (Çelik, 2003).In-structional leadership both focuses on classroom practices and concretizes the identified goals included in the school mission (Bennet and Anderson, 2003).Therefore it is crucial to for school administrators to undertake their job descriptions in a manner that will highlight their instructional leadership roles.Gümüşeli (1996) emphasizes the most important characteristic that differentiates instructional leadership from other leadership styles as the focus on learning processes and its direct relation to teaching processes that include students, teachers and instructional program.Instructional leadership should increase performance in teaching, learning and guidance fields, it should be holistic and pragmatic and include value management and cultural activities (Aytaç, 2000).It is believed that the need for instructional leadership is growing at schools.School administrators are expected to contribute to teachers' professional developments through instructional leadership.

In-Service Training
While education can be classified in various ways, education in work life is generally examined under two headings: pre-service and in-service training.Personnel in sectors that produce goods or services are unable to catch up with the advances and knowledge accumulation due to the fast paced knowledge era, rapid changes in all fields and increased knowledge accumulation.Insufficient pre-service training is perceived as an important problem that needs to be overcome in order to successfully undertake tasks and obtain maximum productivity and efficiency.Educators and business managers that perceive the problem have needed various mechanisms to develop knowledge, skills and experiences of their staff and to provide them with the technological and administrative development in their sectors.One of these mechanisms is in-service training programs.
In-service training is defined as a type of training provided during service which includes systematic provision of required knowledge, skills and behaviors to prepare the personnel for further careers (Armutçuoğlu, 1992;Can, Akgün, & Kavuncu, 1995;Eryılmaz, 1995;Gözübüyük, 1998;Taymaz, 1992).Tortop (1994) regards this process as the goals of in-service training.Ersan (1992) examined in-service training in the context of educational organizations and stated that inservice training term is used to define planned activities implemented to develop the professional knowledge, skills, behaviors and performances of educational staff.Özyürek (1981) listed the reasons that require teacher training through in-service programs as advances in science, changes in society, developments at schools, changes in teachers themselves, changes in teaching processes, developments in the field of child development and the requirement to overcome deficiencies resulting from pre-service training and to fill in the gaps in communication.In-service training programs organized by the Ministry of Education aim to ensure teachers' professional development.

Social Learning among Colleagues
It is known that most learning takes place as a result of social learning via interactions and observations among individuals.Although it was Dewey who pointed to mutual learning concepts for the first time (Bayrakçı, 2007), social learning theory was presented by Bandura to explain learning styles of individuals.In simplest terms, social learning is defined as changes in behavior and knowledge based on observing others' behaviors in social groups (Ganis, 2009).One of the most important principles of social learning theory is individuals' capacity to think about themselves, make judgments and reflect those thoughts and judgments (Senemoğlu, 2004: p. 225).Social learning theory is explained in 4 ways: modeling, observation learning, identification and internalization (Bandura, 1971).Social learning process is composed of four steps: attention, retention, reproduction and motivation (Aydın, 2010, Ganis, 2009, Malone, 2002).
Teachers have the opportunity to interact with their colleagues in various committees and commissions and in social functions.Social learning is expected to emerge as a result of these interactions.

Teachers' Personal Studies
One of the ways individuals learn is through individual work.Individual learning is realized as a result of individual experiences (Ellison & Fudenberg, 1993, Vriend 2000).Learning pace and capacity is different for each individual and everyone has unique learning and study styles.Therefore, same stimuli do not have the same effect on different individuals.Individual learning allows individuals to learn at their own pace and capacity.Individual learning activities give individuals the opportunity to be active in and guide their own learning.Teachers' personal studies are expected to play a role in meeting teachers' professional development needs.

Methodology
The research model is a mixed model type.Findings related to identification of teachers' professional development needs were collected through quantitative methods whereas findings related to systems that meet those needs were collected qualitatively.The study utilized survey model since it identified teachers' professional development needs and investigated the systems that meet those needs.The part of the study related to identification of teachers' professional development needs was quantitative and the section that investigated the systems that meet professional development needs was qualitative.Data regarding the quantitative part of the study was collected with a data collection tool composed of 34 items prepared by the researcher and the data regarding the qualitative part of the study was collected a 5-item data collection tool prepared by the researcher.

Participants
The universe of the study was composed of teachers employed in Gaziantep Province in 2012-2013 academic years.Study sample conssited of a total of 207 teachers selected via "simple random sampling" from the universe.
Table 1 displays that 40.7% of the participants were female and 59.3% were male.58.1% of the teachers worked in primary schools and 41.9% worked in secondary schools.Distribution of participating teachers according to seniority was as follows: 45.9%: 1 -5 years, 26.7%: 6 -10 years, 40%: 11 -15 years and 17.6%: 16 years and higher.87.4% of the participating teachers graduated from undergraduate programs and 12.6% graduated from post graduate programs.87% were teachers whereas 13% were given the title of expert teachers.

Scale Development Process
Data collection tool with three sections developed by the researcher was used in the study to collect data.First section of the data collection tool includes personal information form to identify individual variables; second section is composed of a Likert-type scale to identify teachers' professional development needs and third section consists of a qualitative interview form regarding the systems used to meet teachers' on-the-job training needs.
6-step process proposed by Lester and Bishop (2000) was taken into consideration during the scale development process.Theoretical resources were reviewed in the first step and an item pool related to teacher development was created.In addition, 5 educational inspectors, 5 school administrators and 5 teachers were given semistructured interview forms to obtain their views on teachers' professional development needs and the systems used to meet those needs.The first item pool included 52 items and 5 qualitative questions. 5 school administrators, 5 academicians, 5 educational inspectors and 5 teachers were asked to review the items regarding teachers' professional development needs.Based on the suggestions following the review, similar items were removed, statements were reviewed, number of items was reduced to 38 and the number of qualitative questions was kept the same (5).Items in the item pool were implemented on 85 teachers to test intelligibility.Teacher feedback was received through interviews about several features such as item intelligibility and period of implementation and suggestions were taken into consideration.Cronbach Alpha reliability coefficient of the scale in this step (piloting) was found to be .97.
In order to test content validity based on expert views, the 38-item scale was reviewed again by 5 school administrators, 5 academicians and 5 educational inspectors.These individuals assessed the intelligibility of each item and stated their ideas about the ub groups these items belonged to.They also provided feedback regarding the items suggested for removal or addition.Based on the ideas of the field experts, 4 scale items were removed.Therefore, the scale form used to test reliability and validity included 34 items and 5 qualitative questions.
The draft data collection tool was implemented on 310 teachers employed in the province of Gaziantep and 270 of the returned 275 forms were analyzed.The data collection form composed of 34 items with 5-point Likert type options (None, Very Little, Partially, Mostly and Completely) and 5 qualitative questions was finalized.Teachers were also asked to write their reasons along with the degree of agreement while answering the qualitative questions.

Reliability Analysis and Construct Validity
Construct validity was examined in this study to undertake validity work for the scale.Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) was used to present construct validity of the scale.While CFA is used to assess the degree of overlap between the factors generated from various variables based on a foundation and the actual data, EFA is used to generate few identified meaningful constructs from various items (variables) that can be explained by these items together (Büyüköztürk, 2007).Later, sampling adequacy (Kaiser-Meyer-Olkin measure of sampling adequacy) and Barlett Sphericity analyses were undertaken and KMO measure of sampling adequacy coefficient was found to be .941and Barlett Sphericity test K2 value was calculated to be 4922,481 (378) (p = .000).In order for the data to be adequate for factor analysis, the KMO value should be higher than .60 and Barlett test should be significant (Büyüköztürk, 2007).The fact that KMO values obtained here were higher than .90shows perfect data adequacy for factor analysis (Hutcheson & Sofroniou, 1999).Factor load values of the data collection tool are presented in Table 2.
Factor analysis was undertaken on the scale to identify statistically related items.Rotation: Varimax, a factor analysis method, was used to determine the factor structure of the scale.Factor load values were observed to change between .39 and .80.Items with factor loads that were .39 or higher were collected in the same factor.Factor load values of .45 or higher is a good criterion for selection.However, this value can be decreased to .30for few items (Büyüköztürk, 2007).Items 11,12,19,21,27 and 29 that had no load values under any factor were removed from the scale and the scale was finalized with 28 questions and 4 factors.Factor analysis results showed a scale with 4 factors that were named "extracurricular and classroom activities", "instructional programs and evaluation", "teacher-student relationships" and "organization of instructional environments".Cron- bach Alpha reliability coefficient for each factor was calculated to be .815;.831;.838and .886respectively and the reliability coefficient for the whole scale was .88.

Reliability Analysis and Construct Validity
The scale was declared valid since the facts that the scale explained the total variance with adequate percentage, had high factor loads in three factors and proved that it could evaluate what it set out to evaluate.In addition to EFA, CFA was also implemented on the scale.Factor loads of the model are provided in Figure 1.
Single-factor scale obtained through EFA was applied CFA in AMOS program.CFA showed that all items in the scale fit the 3-factor structure and the obtained goodness-of-fit indices presented good values.Table 3 pre

Reliability Analysis and Construct Validity
Views provided to the question related to "teachers' professional development needs" were calculated in terms of arithmetic means and standard deviation.Independent samples t-test was undertaken to determine whether there were significant differences between the variables of teachers' gender and title and their views and ANOVA analysis methods were implemented to determine whether there were significant differences in teacher views based on seniority and school type.p = .05level of significance was adopted in the study.A Likert type scale scored 1 -5 (None-1; Very Little-2; Partially-3; Mostly-4 and Completely-5) was used in interpreting teacher views regarding "teachers' professional development needs"."Width of Interval = Range/Number of Groups" formula was used to evaluate arithmetic means and score intervals were determined as 4/5 = .80.Descriptive analysis methods were used in analyzing the qualitative data regarding the systems teachers used to meet their professional development needs.Answers provided to each question in the semi-structured interview form were examined separately and in detail, answers that had similar or common aspects were selected and coded.Following the coding, similar answers provided for the same question or answers with common themes were collected under specific categories and teacher views were presented based on the codes.4, based on the factors included in the data collection tool, teachers expressed that they needed "very little" on-the-job training regarding "extracurricular and classroom activities" dimension (mean: 1.97), "very little" on-the-job training regarding "instructional programs and evaluation" dimension (mean: 2.29); "partial" on-the-job training regarding "organization of instructional environments" (mean: 2.61) and "very little" on-the-job training regarding "teacher -student relationships" dimension (mean: 2.57).Teachers expressed that they needed "very little" on-the-job training regarding all dimensions included in the data collection tool (mean: 2.36).Accordingly, teachers need the least on-the-job training in "extracurricular and classroom activities" and the most on-the-job training in "organization of instructional environments".

Discussion
In terms of the dimensions included in the data collection tool, teachers listed their professional development needs as extracurricular and classroom activities", "instructional programs and evaluation" "teachers-student relationships" and "organization of instructional environments" respectively.The fact that teachers need the highest amount of support in educational activities and in instructional programs and evaluation may be related to the fact that these fields have undergone tremendous changes recently.
Based on title variable, there were no significant differences in teacher views regarding their professional development needs in "teacher-student relationships" and "instructional programs and evaluation" dimensions.However, significant differences were observed in teacher views regarding their professional development needs in "extracurricular and classroom activities" and "organization of instructional environments" dimensions based on title.Teachers needed higher levels of on-the-job training in "extracurricular and classroom activities" and "organization of instructional environments" dimensions compared to expert teachers.This finding may be related to the fact that higher levels of competences are required to become expert teachers in career steps practice in Turkey.
Based on seniority, no significant differences were observed in teacher views regarding their professional development needs in "extracurricular and classroom activities", "teachers-student relationships", "instructional programs and evaluation" and "organization of instructional environments" dimensions included in the data collection tool.
Based on place of employment variable, there were no significant differences in teacher views regarding their professional development needs in "teacher-student relationships" and "instructional programs and evaluation" dimensions.However, significant differences were observed in teacher views regarding their professional development needs in "extracurricular and classroom activities" and "organization of instructional environments" dimensions based on place of employment.Compared to primary school teachers, secondary school teachers needed more on-the-job training in "extracurricular and classroom activities" and "organization of instructional environments" dimensions.This finding may be explained by the fact that compared to secondary school teachers, primary school teacher receive more training in vocational topics related to teaching during their pre-service education.
According to qualitative findings of the study, teacher listed how they met their professional development needs from the most to the least as follows: individual/personal studies, social learning among colleagues, inservice training, school administrator and the members of the educational inspection unit.According to this finding, teachers developed themselves the most through personal studies and through social learning and they benefited the least from educational inspectors and school administrators.
Based on the findings of the study, it can be claimed that teachers moderately satisfy their professional development needs via in-service training activities.Bayrakçı (2009) compared in-service training activities provided to Turkish and Japanese teachers and found that Turkish teachers have problems regarding in-service training because the individuals who plan and implement those trainings are not experts.However these trainings are rather successful in Japan due to better technological infrastructure.Özer (2004) stated that although inservice training activities date back to 1960's in Turkey, they are not productive and there are still many problems to solve regarding these activities.
The study concluded that social learning contributed to teachers' professional development.Bayrakçı's (2007) study also found that social learning plays an important role in individuals' learning and Solomonidou & Kolokotronis (2008) and Pilatou & Stavridou (2008) states that knowledge is created in social environments and social environments are effective in science education.

Conclusion
With each passing day, teachers feel the need for continuous professional development due to increased knowledge accumulation as a result of changes and transformation.Effective implementation of educational services depends on meeting these needs.It is found that teachers have professional development needs in the areas of "extracurricular and classroom activities", "instructional programs and evaluation" "teachers-student relationships" and "organization of instructional environments" respectively.It is observed that teachers satisfy these professional development needs respectively through individual studies, social learning among colleagues, in-service training, school administrators and educational inspection systems.It can be suggested that education, selection and assignment of administrators and educational inspectors should be reviewed in order to create more effective inspection units and school administrations that will satisfy teachers' professional development needs.Also, planning and implementation of in-service training activities geared towards teacher development can be undertaken more professionally.
