A SHORT REVIEW of TPACK for TEACHER EDUCATION

The aim of this descriptive study is to examine review of the ICT and TPACK literature for teacher education. Firstly, the general characteristics of the ICT and TPACK have been examined. In the study, the researchers answer the questions namely “How is the distribution of the articles of TPACK of the year?”, “How is the distribution of the subject of article of ICT and TPACK?”, “What is the distribution according to the year of the subject of article of ICT and TPACK?” and “How can we integrate the TPACK to our teacher training program?” 116 articles were analysed. It focused on ICT and TPACK and findings and discussions were conducted. The study presents some recommendations to the teacher education.

processes, principles, theories, and skills within a field of study (Shulman, 2004).Technological Content Knowledge (TCK) Technological content knowledge understands technology in a specific subject or discipline; and represents technology.Pedagogical Content Knowledge (PCK) Blends the content and the pedagogy into understanding of how these are associated for successful teaching (Shulman, 1986): The category of pedagogical content knowledge includes the most regularly taught topics in one's subject area, the most useful forms of representation of those ideas, the most powerful analogies, illustrations, examples, explanations, and demonstrations, in a word, ways of representing and formulating the subject that make it comprehensible to others.Pedagogical content knowledge also contains an understanding of what makes the learning of specific topics easy or difficult; the conceptions and preconceptions that students of different ages and backgrounds bring with them to the learning of those most frequently taught topics and lessons (p.9).Technological Pedagogical Knowledge (TPK): Technological pedagogical knowledge understands how technology can shape the ways of teaching.PCK is described as the relationship between the teaching subject and associated pedagogy.For (Shulman, 1987), pedagogical content knowledge identifies the distinctive bodies of knowledge for teaching.It represents the blending of content and pedagogy into an understanding of how particular topics, problems or issues are organized, represented, and adapted to the diverse interests and abilities of learners, and presented for instruction.Pedagogical content knowledge is the category most likely to distinguish the understanding of the content specialist from that of the pedagogue.(p.4).In teacher education, Pedagogical Content Knowledge has been seen as an important support for teachers' professional development.In order to acquire and update their skills, teachers must keep pace with increasing educational requirements that necessitates adaptable strategy and a long time commitment.An important factor that can help mathematics teachers keep their potentials is the use of technology in classrooms.

Technological Pedagogical Content Knowledge (TPACK):
The use of technological tools that helps in delivering PCK (Mishra and Koehler, 2006).TPACK-The new acronym for TPCK (Thompson and Mishra, 2007).
The TPACK theoretical framework has been adopted by different researchers in a multitude of educational areas, and is considered to have shown promising results in integrating technology in teachers' practices.In education such as mathematics education, there have been several studies in using the TPACK framework.Researchers have acknowledged the lack of adequate theoretical and professional frameworks that provide help, guidance, and efficiency to teachers to integrate technology in classrooms (Koehler and Mishra, 2005;Mishra and Koehler, 2006;Niess, 2008;Niess et al., 2009;Valanides and Angeli, 2008a).Many different approaches have been attempted in order to help teachers overcome difficulties of integrating technology in mathematics classrooms (Hew and Brush, 2007) Technology and ICT were integrated in teaching and learning for teachers, students, educators so on.Research results show evidence of technology being implemented widely in classrooms for teaching (Cuban, 2001;Guzman and Nussbaum, 2009;Hew and Brush, 2007;Kincaid and Feldner, 2002;Lawless and Pellegrino, 2007;McCormick andScrimshaw, 2001, Banas 2010).Other research results have also asserted that a great number of teachers remain unprepared to use computers in teaching (Cuban, 2001;Hokanson and Hooper, 2004;Russell et al., 2003).Educationtechnology integration is called the Technology Pedagogical Content Knowledge (Yurdakul, Examining techno pedagogical knowledge competencies of preservice teachers based on ICT usage., 2011, p. 398).Firstly it focused on content know-ledge in these processes (Shulman, 1986;Koehler and Mishra, 2005;Mishra and Koehler, 2006).Technological Pedagogical Content Knowledge (TPACK), technology program content and pedagogical approaches to connec-ting content, pedagogy and technology information field describe the type of interaction (Shin 2010).This model represents teachers' teaching-learning process on how to integrate the technology of technological, pedagogical and content knowledge of the structure.It consists of TPACK, the interaction and combines three information fields (Harris et al., 2009).How to use information technology in teaching pedagogy of various technologies, knowledge, and ability to express change the way teachers teach using technology (Shin 2010).To integrate technology in education, learners and teachers continue to struggle with issues of using educational technology in teaching and learning.Teachers and teacher trainees should adopt seven kinds of knowledge using pedagogical approaches.

Purpose
The purpose of this literature review was to examine the theoretical basis, practical use of TPACK and the development of the TPACK framework.The purpose of this paper is to understand what role, if any, the TPACK construct can provide in advancing the new agenda in teacher education.This study may guide teachers, researchers, teacher educators, educationalists, program makers and so on.ICT and TPACK literature might be analysed according to years.

Research questions
The present study is a qualitative study (Miles and Huberman, 2014).This study has used a descriptive method.A literature review was conducted to answer these research questions.
1. How is the distribution of the articles of TPACK of the year? 2. How is the distribution of the subject of article of ICT and TPACK? 3. What is the distribution according to the year of the subject of article of ICT and TPACK? 4. How can we integrate the TPACK to our teacher training program?LITERATURE REVIEW Shulman (1986) asserted that teacher must be organized with content knowledge, curricular knowledge, pedagogical strategies, and pedagogical content knowledge upon which to base professional judgment.Using instructional strategies and programs that have been empirically evaluated can validate the selection of pedagogy.One of the most important ways of providing technological support is to use a framework for integrating complex problems of knowledge from pedagogy, content, technology, and different forms of interactions among these elements in classrooms (Mishra and Koehler, 2008).Adapted from the Pedagogical Content Knowledge model (Shulman, 1986(Shulman, , 1987)), the Technological Pedagogical Content Knowledge (TPCK) model is a framework that treats technological integration in education "as a way of thinking about the knowledge [that] teachers need to understand how to integrate technology effectively in their classrooms" (Mishra and Koehler, 2006 pp. 10-11).TPCK, later renamed as TPACK (Thompson and Mishra, 2007), is comprised knowledge of content, pedagogy, and technology, as well as skills to use the interactions among these components (Koehler and Mishra, 2008).
When introducing educational technology in classrooms, researchers noticed that the PCK framework did not explicitly support technology.There were some attempts to adapt the old PCK framework.Some of them, such as TPACK, offer adequate support for technology and offer more opportunities to see how integration of the technology takes place.Since the end of the 1990s, there were several attempts to adapt Pedagogical Content Knowledge to the use of educational technology.From all, the Technological Pedagogical Content Knowledge (TPACK) framework developed by Mishra and Koehler (2006) is the most well-known.
TPACK is an extension of the PCK, defined as a systematic approach to joining technical expertise in teaching with pedagogical content knowledge.TPACK is an emergent model resulting from the intersection of technology, pedagogy and content.This model considers the context as an important aspect.Teaching practices are very important as a source of learning and not just as a consequence of applying a set of learning theories.The TPACK framework offers many insights into how technology should relate to other components of education in order to be successful.This framework offers clear explanations of why technology should not be treated in isolation but related with required pedagogy and content (Mishra and Koehler, 2006).

Identifying journal articles
The literatures were identified in September 2014 by first exploring ERIC database, EBSCOHOST, the Web of Science database and Scopus database.The ICT, TPACK, TPCK, "technological pedagogical content knowledge" entered as keywords.116 articles has been reached.Only directly related articles were examined.All articles were read, analyzed and coded.All results were represented as a the line graph, the bar graph and the spider graph.

Coding scheme
All articles, subject, content as sub-themes were grouped into themes and years.Themes and years were converted into categories.Basic data, themes of research are also taken into account.Two researchers coded each article.Reliability and validity were considered.The coders' agreements were found as .96(Bogdan and Biklen, 2007).

Limitation of the study
This review of literature was limited in technological pedagogical content knowledge.In focusing on the TPACK framework, additional limitations are obvious in the types of manuscripts available and the venues in which these manuscripts are presented.

The second research question is how is the subject of article of ICT and TPACK distributed?
The present study also analyzed the articles based on the two dimensions ICT and TPACK.Based on these  criteria, all 136 studies were analyzed and the outcomes are provided below (some of studies both related to the ict and tpack).51 articles were related to ICT and 82 articles were related to the TPACK.Table 2 provides a summary of the content analysis of ICT and TPACK.

The third research question is the distribution according to the year of the subject of article of ICT and TPACK
Researchers have acknowledged the lack of adequate theoretical and professional frameworks that provide help, guidance, and efficiency to teachers to integrate technology in classrooms (Koehler and Mishra, 2006;Niess, 2008;Niess et al. 2009;Valanides and Angeli, 2008).Many different approaches have been attempted in order to help teachers overcome difficulties of integrating technology in mathematics classrooms (Hew and Brush, 2007).Figures 4 and 5 give emphasis on ICT and TPACK studies.After 2009, Tpack studies have been increased.ICT studies have been increased up to 2009.This is to show that ICT is not only enough for teaching and learning.
Finally, we would like to point out the possibility of cross fertilizing some older framework for the study of ICT integration with the TPACK framework (Figure 6).Established framework such as the technology acceptance model, concern based adoption model and the three models of knowledge creation as reviewed by Paavola et al., (2004) could be brought to bear on TPACK.For example, researchers can possibly envision the acceptance of certain emerging technology by analyzing its TPACK properties and the possible stages of concern that would follow when the technology is implemented.Angeli and Valanides (2009) asserted that the growth or proficiency of each TPACK knowledge construct does not automatically increase the educator's overall TPACK knowledge (Figure 7).Present research found significant relationships between teachers' TPACK level (Lee and Tsai, 2010;Niess et al., 2006) and their self-confidence in technology, pedagogy, and content (Lee and Tsai).The future studies might focus on teacher characteristics in relation to TPACK and the development of TPACK.Their general conclusion support the foregoing section in that they also found that most intervention produced positive outcomes, especially for TK and pre-service teachers' willingness to use ICT.As illustrated by their work, the TPACK framework can be a common conceptual framework for many more review studies (Figure 7).We would argue that more surveys that compare pre-service teachers TPACK could be helpful in identifying the gaps in their TPACK and teacher educators can then plan how to support the continuous development of TPACK.This is especially so for the faculties in higher education as they are likely to be the most important people to help form the pre-service teachers' TPACK.

The fourth research question is how do we integrate the TPACK to our teacher training program?
In the teacher training faculty mostly cover three area of knowledge that teacher trainees have to be known.In this study asserted that the components of the TPACK models are enlightened (Table 3).The TPACK framework is a generative framework with many more possible future applications.In this paper, we have reviewed a sizable and representative set of studies and pointed out many possible directions for future research.Based on our review, we would propose a revised representation of the TPACK framework to guide future research as depicted.We can ask how we can integrate TPACK in teacher education program.For these, instructional planning process was given as an example.
The problems with teacher education made a lot of countries re-question its teacher education systems and hence start restructuring them to support social coherence, teaching performance and national enlargement.
For this an application of TPACK was recommended in Table 3.

DISCUSSION AND CONCLUSION
This information has to answer the question of how technology will change the teaching-learning process when used in certain ways (Kuskaya and Usluel, 2010).Yurdakul (2011) in terms of competencies in general education teacher candidates' techno pedagojik study concluded they see themselves advanced.As seen        literature reviewed, we identified four interdependent contextual factors that are to a certain extent characteristic.To sum up, Angeli and Valanides (2009) argued that the growth or proficiency of each TPACK knowledge construct does not automatically increase the educator's overall TPACK knowledge.We would like to point out the possibility of cross fertilizing some older framework for the study of ICT integration with the TPACK framework.
For instance, researchers can possibly imagine the acceptance of certain emerging technology by analyzing its TPACK properties and the possible stages of apprehension that would follow when the technology is implemented.All literature review showed that ICT not only enough, also we need the tpack for teaching and learning.While illustrated, the TPACK framework can be a general conceptual framework for many more review studies.In addition, we suggest that TPACK could also be used to analyze policy documents to examine whether there is a shift towards the use of overlapping constructs namely TPACK to formulate policies or standards, which could reflect a deeper understanding among policy makers.
