SCIENCE TEACHERS ’ ICT USE FROM A VIEWPOINT OF TECHNOLOGICAL PEDAGOGICAL CONTENT KNOWLEDGE ( TPCK )

In order to develop science teachers’ Technological Pedagogical Content Knowledge (TPCK), a better understanding of how teachers use ICT in classroom practice is needed. This paper examines Finnish chemistry teachers, knowledge, skills and beliefs on using ICT in education in comparison to other science teachers. The study shows that chemistry teachers have positive beliefs of using ICT and computers as a tool for teaching and learning. Teachers’ earlier training in the use of ICT had increased their beliefs towards using ICT. The study shows that, in general, teachers have good basic ICT skills, but lack skills to integrate ICT into education, due to a lack of technological content knowledge (TCK) and technological pedagogical knowledge (TPK). The results show that teachers especially lack knowledge on subject-specific software, such as modelling software. The results suggest that chemistry teachers need more ICT-training from the viewpoint of TPK and TCK in order to help them get ideas and materials that can be directly applied to classroom practice, and to acquire experience to develop their own TPCK. The results give implications on how science teachers’ in-service training can be developed.


Introduction
Teachers' professional development is a key for successful integration of information and communication technology (ICT) at school level.(Ertmer & Ottenbreit-Leftwich, 2010;Clarks & Hollingsworth, 2002;Pernaa & Aksela, 2009) In previous studies, Voogt (2010) and Rogers & Twidle (2014) found that teachers' participation in subject-specific ICT-training increased ICT integration in the classroom, which was supporting notification of the importance of Technological Pedagogical Content Knowledge (TPCK).In order to increase science teachers' TPCK, there is a need to increase understanding on science teachers' ICT use in classroom practice.
Based on Shulmans' (1986) concept of Pedagogical Content Knowledge (PCK), Mishra & Koehler (2006) introduced a concept of Technological Pedagogical Content Knowledge (TPCK).TPCK is complex knowledge how to use various technologies to teach, represent and facilitate knowledge creation of specific subject content (Chai, Koh & Tsai, 2013).TPCK consists of several domains of knowledge.Technological knowledge (TK) is continuously changing knowledge how to use various software and hardware.Pedagogical knowledge (PK) is knowledge of all processes of teaching and learning, and content knowledge (CK) is knowledge of a subject matter.PCK is knowledge of the pedagogies, teaching and learning processes relevant to learning and teaching a subject matter.TCK is knowledge about how technology is used to present essential contents of a subject matter.TPK is knowledge of technologies used in teaching and learning settings and knowledge how technology might change teaching.(Schulman, 1986;Mishra & Koehler, 2006;Koehler et al., 2007) TPCK is dynamic, integrative and transformative knowledge of technology, pedagogy and content of a subject matter needed for pedagogically meaningful integration of ICT in teaching.
There are several challenges and barriers to overcome before ICT is used extensively in the classroom.One may think purchasing adequate equipment in schools is enough for the effective use of ICT.It might be a sufficient stimulus for some teachers but not for all.
Integration of ICT requires enough hardware, Internet access, proper software, materials, training and support.This is called "first-order barriers" or "external barriers" (Ertmer, 1999).Additionally, other teachers' opposing beliefs are significant first-order barrier (Ertmer et al., 2012).Goktas et al. (2013) studied possible barriers encountered by Turkish primary school teachers in ICT integration.The barriers were the first-order barriers which could be overcome e.g.allocating more budged.The first-order barriers might be overcome and teachers might have good ICT skills but use of ICT for teaching and learning purposes is hindered by teachers' own beliefs of its relevance.This is called "second-order barriers" or "internal barriers" (Ertmer, 1999;Ertmer et al., 2012).
Teachers often easily reject innovations which are inconsistent with their personal conceptions of teaching and learning (Pajares, 1992).Educational beliefs and orientations of teachers and students are stable and chancing them later is resisted.(Goktas et al., 2009;Juuti et al. 2009;Prestridge, 2012) However, positive results about teachers' changed attitudes have been gained after offering experiences in ICT integration into traditional teaching (Barak, 2007;Hennessy et al., 2005).Hence, diffusion of innovations need to be supported in the real context (e.g.Lavonen et al., 2006) and teachers need time to make changes (Ertmer & Ottenbreit-Leftwich, 2010).Thus, ICT integration from top to down usually is not successful.Papanastasiou & Angeli (2008) observed in their studies that the computer use, even on personal level, might lead the integration of ICT in practice.Additionally, Paraskeva, Bouta & Papagianni (2008) and Tezci (2010) noticed teachers being experienced with computers have better self-efficacy and more positive attitudes toward technologies, and therefore, integrate more ICT in teaching than less experienced.Self-efficacy, in this content, is perceived as ability to incorporate ICT in the practice (Abbitt, 2011;Watson 2006).In addition, support from school seemed to be important for using ICT in teaching and learning settings.(Ayub, Barak & Ismail, 2012) Teachers' constructivist-oriented pedagogical beliefs predict the integration of ICT in the classroom constructivist way.(Feng et al., 2014;Teo et al., 2008;Tondeur et al., 2008) Teachers believing traditional teaching tend to use technology in traditional way in which teacher is a source of knowledge and students are passive recipients.(Teo et al., 2008) Lim & Chai (2008) refers several previous studies and claims that teachers' pedagogical beliefs need to be change from traditional to constructive prior to effective use of ICT for learning purposes.Prestridge (2012) found that teachers who were competent at using ICT were more confident in using ICT in the classroom.However, ICT might be used as a traditional, teacher-centered approach.Professional development is needed to help teachers to transform their practice.

Teachers' technology knowledge
This section will examine teacher's knowledge of software and the frequency of the software use.

Software knowledge
The computer knowledge of teachers was analyzed using Likert scale 1-to-5 with response options of "I cannot use it", "I can use it to a small extent", "I can use it satisfactorily", "I can use it well" and "I can use it very well".When comparing the software knowledge of the chemistry teachers and the other teachers the non-parametric Mann-Whitney U-tests showed two statistically significant differences (p < 0.01), knowledge of modelling software (z = -4.339,p = 0.001) and programming languages (z = -2.585,p = 0.010).Additionally, there were three significant differences (p < 0.05) in knowledge of data logging (z = -2.544,p = 0.011), simulations (z = -2.417,p = 0.016) and e-mail (z = -2.333,p = 0.020).Scale: 1 "I cannot use it", 2 "I Can use it to a small extent", 3 " I can use it satisfactorily", 4 "I can use it well", 5 "I can use it very well".(Papanastasiou & Angeli, 2008) When comparing the mean scores of software knowledge there were only slight distinction between the chemistry teachers and the other teachers (Table 2).All teachers had good knowledge (mean scores > 3) in common software tools, such as, word processing (mean scores for chemistry teachers 4.4 and for the others 4.3), spreadsheet (3.6 and 3.5), presentation tools (4.0 and 3.8) and graphics (3.0 and 3.0), in addition to, Internet (4.4 and 4.3) and email (4.6 and 4.4).Knowledge of specialized software was poor.The chemistry teachers were more experienced than the other teachers in modelling (1.7 and 1.2), simulation (1.9 and 1.4) and data logging (1.9 and 1.6).Programming languages (1.5 and 1.9), publishing software (1.8 and 2.0) and databases (1.8 and 2.0) were not well known.

Frequency of software use
Frequency of software use for personal purposes was analyzed using Likert scale 1-to-5 with response options of "Never", "Once or twice a semester", "Once or twice a month", "Once or twice a week" and "Almost every day".The frequency of software use between the chemistry teachers and the other teachers was almost identical.Except for the computer programming which was used more frequently by the other teachers causing the only significant difference (z = -2.427,p = 0.015) in the Mann-Whitney U-test.Cronbach's alpha was 0.797.
According the mean scores, word processing (mean scores for the chemistry teachers 4.2 and 4.2 for the others), Internet (4.9 and 4.9) and communication tools (5.0 and 4.9) were used almost daily (table 3).Computer games, spreadsheets, presentation tools, graphical applications and publishing tools were used on average less than weekly (mean scores < 3).

Barriers hindering integration of technology to pedagogy and contents
Next there will be explained teachers' (i) self-efficacy and beliefs about ICT in teaching, (ii) beliefs about ICT as a teaching and learning tool, and (iii) the first-order barriers for the use of ICT.

Self-efficacy and beliefs about ICT in teaching
The beliefs and self-efficacy about … were studied with Likert scale 1-to-5 with the response options of "Completely disagree", "Disagree", "Neutral", "Agree" and "Completely agree ".
The Mann-Whitney U-test showed three significant differences: "The computer is a valuable tool for teacher" (z = -1.979,p = 0.048), "I can do what the computer can do equally as well" (z = -1.964,p = 0.049) and "I can teach my students how to make their own web pages" (z = -2.510,p = 0.012).Scale: 1 "Completely disagree", 2 "Disagree", 3 "Neutral", 4 "Agree", 5 "Completely agree ". (Papanastasiou & Angeli, 2008) According to the mean scores (Table 4), the chemistry teachers agreed more with "computers are valuable tools for teachers" (the mean scores 4.7 and 4.4), "the computer changes the way of teaching" (4.1 and 4.0), and "helps to teach in more effective ways" (3.7 and 3.6).The computers are regarded with no suspicion even though they were reported to cause various challenges and technical problems in the classroom.The use of the computers were not felt scaring (1.8 and 1.9) or stressing (2.7 and 2.8) but quite exiting (3.9 and 3.8).The teachers thought they can solve possible problems with software or hardware quite well: "If something goes wrong I will not know how to fix it" (2.6 and 2.7).Students were thought to learn and understand concepts more efficiently with the computers (3.3 and 3.2) The teachers were confident in using ICT in teaching and learning settings.They were capable of selecting appropriate software to be used in teaching (the mean scores for the chemistry teachers 3.8 and for the others 3.6), planning technology-enhanced lessons (3.3 and 3.3) and using the Internet to attain certain learning goals (4.0 and 4.0).They were able to select appropriate software for students' projects (3.3 and 3.4), and to use PowerPoint in the classroom (4.6 and 4.3), but teaching to web pages making was poorly known (1.9 and 2.5).Cronbach's alpha was 0.504.

ICT as a teaching and learning tool
The teachers' beliefs about ICT as a teaching and learning tool were studied with eight statements using a scale "Agree (with a score 1)", "Disagree (-1)", "Neither ( 0)" based on the previous study of Wikan & Molster (2011).
In the Mann-Whitney U-test only one significant difference was found: "ICT improves learners' presentations or assignments" (z = -2.055,p = 0.040).Scale: 1 "Agree", -1 "Disagree", 0 "Neither".(Wikan & Molster, 2011) According to the mean scores, the chemistry teachers regarded ICT as teaching and learning tool slightly more positively than the other teachers: "ICT increases the ways of teaching and learning" (mean scores for chemistry teachers >0.9 and <0.9 for the others) and "ICT makes lesson diverse" (0.9 and 0.8) (table 5).The teachers also thought "ICT facilitates finding new information" (>0.8 and <0.8).The chemistry teachers believed more than the other teachers that "ICT improves learners' presentations and assignments" (0.7 and 0 .4 ) and "ICT increases motivation" ( 0 .5 a n d 0 .4 ) b u t s l i g h t l y l e s s t h a t "ICT supports independent learning" (0.4 and 0.5).All teachers agreed less with "ICT enhances subject learning", "ICT supports collaboration" and "ICT makes working faster".The chemistry teachers, somewhat, disagreed with "ICT makes learners work harder" and all teachers disagreed slightly with "ICT disturbs in pupils' concentration".Cronbach's alpha was 0.785.

First-order barriers
The possible first-order barriers hindering the effective ICT use were analyzed using Likert 1-to-5 scale with response options of "Completely disagree", "Disagree", "Neutral", "Agree", and "Completely agree".In the U-test no significant differences between the teacher groups were noticed.Based on the mean scores the barriers were quite similar to all teachers.The main barrier was lack of time, in particular, for the chemistry teachers (4.1 and 3.9) ( 1 "Completely disagree", 2 "Disagree", 3 "Neutral", 4 "Agree", 5 "Completely agree ". (Goktas et al., 2009) Other teachers mentioned barriers were lack of money, behavior of pupils and lack of skills of colleagues.
"No money for buying techniques", "Problems in municipal economy", "Commercial software could not be bought" "Behavior of pupils", "Lack of skills and knowledge of other teachers, and therefore, no collaboration"

Need for support and training
There it will be explained next (i) teacher's views of school's climate and support, (ii) teachers' views' of teaching approach and assignment type, (iii) teachers' need for in-service training and support:

School's climate and support
School's climate and support were studied using Likert scale 1-to-5 with response options of "Completely disagree", "Disagree", "Neutral", "Agree" and "Completely agree".However, no significant results were noticed in the Mann-Whitney U-test.According to the mean scores, school's climate and support were good.The value of ICT in teaching and learning was well understood amongst the participants (the mean scores for the chemistry teachers were 3.5 and for the others 3.6) (Table 7).Cronbach's alpha was 0.823.

"I use ICT only if some additional values for teaching are obtained with it"
The encouragement for integrating ICT in teaching and learning were good by the principals (3.6 and 3.7), ICT coordinators (3.3 and 3.3) and other teachers (3.5 and 3.3).The chemistry teachers shared ideas and encouraged each other slightly more than the other teachers (3.6 and 3.5) but ICT in the school curriculum was not frequently discussed (3.0 for the both groups). 1 "Completely disagree", 2 "Disagree", 3 "Neutral", 4 "Agree", 5 "Completely agree ". (Papanastasiou & Angeli, 2008) If desired, teachers were able to add comments on climate and support in the open-ended question.Peer support was regarded important.

"It's enough to have one or a few eager teachers…"
"Climate is generally supportive and teachers support each other", "Lack of skills of other teachers, and therefore, e.g.no collaboration…" However, technical support were less adequate and financial resources were exiguous.
"There should be own technical support at school all the time" "ICT educators" "Because there are no devices, it's impossible to use ICT regardless of climate…" "No money to buy software we would need", "No resources to buy tablets" "Technical help"

Teaching approach and assignment type
Teachers were asked to select which teaching style they prefer to student-centered or teachercentered.Sixty-four percent (56) of the chemistry teachers and 63 % (64) of the other teachers preferred student-centered style.Similarly, they were asked to select which types of assignments they prefer to open-ended or closed.53 % (47) of the chemistry teachers and 61 % (62) of the other teachers preferred open-ended exercises.However, some teachers commented it is impossible to select because the teaching style and the exercise type are dependent on a situation and a content.

The need for in-service training and support
Circa 78 % of all teachers and 75 % of the chemistry teachers had participated in ICT inservice training.Duration of the trainings ranged from a few hours to a few days.Forty of the teachers mentioned they had participated in training, without specifying the answers.Participation in ICT training was perceived to cause statistically significant differences in the U-tests with the statements "The computer can help students understand concepts more easily" (z = -2.697,p = 0.007), and "ICT supports collaboration" (z = -2.894,p = 0.004).
Significant differences were found with "The computer helps teachers to teach in more effective ways" (z = -2.361,p = 0.018) and "ICT supports independent learning" (z = -2,070, p = 0,038).However, ICT training caused no meaningful differences of knowledge and the frequency of software use, barriers or school's climate and support (results not shown).
There were 120 answers in the open-ended question about need for ICT in-service training.Subject-specific ICT trainings were suggested in chemistry (n = 9), in physics (n= 3), in biology (n = 1) and in geography (n = 1).
"Data logging training", "Chemistry and ICT", "Mobile applications, suitable for secondary school, in which geography has the main role." Teachers needed training how to use ICT in mathematics (n = 21), and in programming (n = 11).The teachers in mathematics were lacking in high quality software suitable for the subject learning.Pen and paper often are more practical.
"Teaching mathematics with ICT", "Ideas how to use technology in the math classes 7-9", "Programs suitable for mathematics, e.g.how to replace pen and paper.Now, pen and paper is faster than writing calculations with a program.Thus, ICT slows but not improves.Some program give an answer, but it does not help to understand, how the answer was gained." "HTLM5-programming…", "Java-script programming…" Seven teachers desired ICT training from pedagogical point of view.

"Suitable pedagogical models, how to use tablets in teaching", "What added values ICT brings to pedagogy?"
Training how to make e-materials and digital exams were desired (n = 14).The requirements of the upcoming digital matriculation exams cause the uncertainty and need for training (n = 7).The ideas for the tablet or iPad usage was also desired (n = 10).Some specified software e.g.multimedia tools were mentioned.
There were number of unspecified answers e.g.Many of the teachers were in need of rather basic software training to get ideas or readymade materials.Some of the participants expected differentiated training for experienced teachers.
"In-service trainings tends to be aimed for the fools"

Conclusions and discussion
The chemistry teachers' ICT knowledge, skills, beliefs and usage were quite similar to other science teachers.However, there were some small distinctions between the teacher groups which might be caused by nature of chemistry and requirements of technological, pedagogical and content knowledge needed in the classroom practice.

Technological knowledge of chemistry teachers
Although technology is not the end, teachers need knowledge of technology itself and latest technological skills to develop their TPCK for effective ICT integration in the classroom.
Similarly to previous studies of Papanastasiou & Angeli (2008) and Tezci (2010) software knowledge of Finnish chemistry teachers was divided into two groups: well-known common software applications and less-known specialized software applications.Although, knowledge of subject-specific applications caused significant differences between the chemistry teachers and the other teachers, technological knowledge of these applications were poorly known.Additionally, both knowledge and use of computer programing software caused significant difference between the teacher groups, though knowledge and skills of all teachers were poor.
The chemistry teachers used computers, at least for personal tasks, almost daily.The frequency of software use was divided into three groups: used almost daily, used less than a few times in month, and used hardly ever.This is in line with findings of Paraskeva et al., (2008) who observed that Creek teachers had moderate experience and one-sided use of applications.
Although, according to Ertmer & Ottenbreit-Leftwich (2010), technological knowledge itself is not enough for the effective use of ICT, Papanastasiou & Angeli (2008) noticed personal use of the computers increases the ICT integration in the classroom.Similar effect was observed here.The both teacher groups were capable of using the frequently used common software (e.g.PowerPoint or Internet) in the classroom to accomplish certain learning goals.However, the poorly known specialized software, e.g.web page making, could not be taught.According to Brun & Hinostroza (2014) advanced and complex pedagogical activities are usually less frequent and requires adequate professional development.
Advanced pedagogical activities requires good TPCK of teachers.Teachers' pedagogical activities in the chemistry classroom need to be investigated more carefully from TPCK viewpoints.

The first-order barriers hindering ICT integration
Technological knowledge is not enough if teachers are uncertain of its use (Ertmer & Ottenbreit-Leftwich, 2010).In particular, the chemistry teachers perceived the computer as a valuable tool for teachers, and they could not do things as well as the computers, which caused significant differences in the U-tests.In chemistry e.g.data-logging, simulations and computer modelling are essential subjects, thus increasing teaching methods when used in the classroom.This may explain, why chemistry teachers regarded computers as valuable and important, and experienced lack of hardware as one of the main barriers.
The teachers' confidence and self-efficacy of using the common software was regarded high and difference between the teacher groups was minor based on the mean scores.This is consistent with the previous findings.Paraskeva & Angeli (2008) and Prestridge (2012) noticed teachers who use more technology are more competent and confident in using it but also more open for new ideas and more likely to use ICT in the classroom successfully.If teachers do not have self-confidence and self-efficacy of using ICT its integration is likely to be hindered (Watson, 2006).Hence, getting familiar with technologies teachers' positive attitudes toward ICT may be developed, followed by the increased ICT integration in the classroom.(Tezci, 2010) Development of TPCK requires experiences of ICT in the practice.
Prior to teach with technology teachers need to expand their knowledge of pedagogical practice (Watson, 2006).Beliefs are related to values regarded important, in particular, for learning outcome.If ICT supports achieving most important instructional goals teachers are likely to use it.(Ertmer et al., 2010) In this study the teachers had positive thoughts of ICT as learning tool.They believed technology is effective for learning outcome which helps to find new information, understand concepts better and develop thinking skills.On the other hand, they agreed with that ICT increases students' motivation and subject learning, and they agreed slightly with that ICT supports students' collaboration or independent learning.These beliefs are in the major role in student-centered teaching approach.Teachers' pedagogical beliefs are deeply-rooted and chancing them later is challenging.(Goktas et al., 2009;Juuti et al. 2009;Prestridge, 2012) Prior experiences of ICT have strong influence on teachers' beliefs, and therefore, ICT integration (Ertmer & Ottenbreit-Leftwich, 2010).Based on the previous studies (Feng et al., 2014;Teo et al., 2008;Tondeur et al., 2008)  Teachers' self-reported barriers here were not so much second-order barriers (own beliefs) but first-order barriers (lack of sufficient hardware, Internet access, proper software, materials, training and support) (Ertmer, 1999).The findings were similar to previous study of Pernaa & Aksela (2009), the chemistry teachers were lacking in time and hardware but also materials, course contents and instructional programs, although differences between the teacher groups were not statistically significant.Additionally, a few teacher in mentioned heavy course loads as a barrier.Particularly, the chemistry teachers did not regarded basic ICT knowledge as barrier but knowledge for ICT integration were perceived moderate barrier by the both teacher groups.The findings were quite similar to the study of Goktas et al., (2013) who studied Turkish primary school teachers.Although, heavy course loads were challenge in Turkey, as well, decreasing the loads would not be a leading enabler for ICT usage.Similar to Turkish teachers, Finnish teachers believed allocating more budged and peer support would be enablers.Therefore, insufficient use of ICT might be caused more by lack of equipment, and less by lack of TPCK.
As Tsai & Chai (2012) discussed, lack of teachers design thinking skills, called "thirdorder barriers", might be a remaining barrier after removing first-and second-order barriers.Design thinking skills are needed to use ICT in right time and right place regardless of environment, which requires highly advanced TPCK.Although, there were no significant differences between the teacher groups here, teachers experienced support from colleagues and schools were sufficient.And particularly, the chemistry exchanged ideas with colleagues.The supportive climate in the school is vital for successful ICT integration (Ayub, 2012).Collaborating and talking with other teachers, in addition to active learning and reflection were found to have effective contributions to successful ICT integration and changing teachers' beliefs (Rogers & Twidle, 2014).

Support and training needed to develop TPCK
The chemistry teachers' technological knowledge was restricted.They evaluated to have good basic ICT skills but they were lacking in skills needed for ICT integration indicating deficiency of TCK or TPK.The teachers had positive beliefs of using ICT in teaching and learning settings which still need to be strengthen with experiences of students' positive learning outcomes.However, they did not have enough hardware and time, which might are the main reasons for a limited integration of ICT hindering development of their TPCK.
prior to use ICT meaningfully in the classroom teacher have to change teaching style to student-centered.In this study, especially the chemistry teachers believed ICT changes their teaching method and enriches the lessons.However, it is not known whether it means the change from teacher-centered to student-centered.Over 60 % of the teachers preferred student-centered teaching style, and furthermore, 53 % of the chemistry teachers and 61 % of the other teachers favored open-ended assignments.Though, some teachers reminded it is impossible to choose which one to prefer because it dependents on the content and the situation.This indicates they use diverse methods.Wikan & Molster (2011) noticed the teachers participated in the long-term ICT-training used more student-centered teaching style than teachers participated only in short-term trainings.Long-term ICT-training might be needed to give experience of better learning outcomes of student-centered methods to the chemistry teachers.Thus, positive experiences of better learning outcome might increase teachers' positive beliefs and integration of ICT in the practice strengthening teachers' TPCK.
Almost all teachers had participated in some short-term ICT-training during their careers as teachers.Participation in ICT in-service training was noticed to increase positive beliefs of teaching and better learning outcome.Even the short training was found to influence on teachers' ICT beliefs favorably but not on knowledge or use of ICT.Interestingly, Wikan & Molster (2011) found teachers' participated in long-term ICT-training and professional development used ICT more in the classroom and were more confident and competent than those participated only a short-time training.In this case more investigations need to be done to make further conclusions.Teachers wished to have in-service training in software and hardware use, which is important to gain sufficient technological knowledge.This is the first, but not sufficient, step toward effective ICT integration.If getting experience of technology itself only, teachers are less likely to incorporate it in practice (Ertmer & Ottenbreit-Leftwich, 2010; Rogers & Twidle, 2014).Many teachers did not have ideas or skills how to integrate ICT in the subject matter, indicating they need more training to gain technological content knowledge or technological pedagogical knowledge in curriculum context (Roger & Twidle, 2014).A few of the teachers wished to have ICT-training from pedagogical point of view, possibly indicating subconscious thoughts of TPCK.In-service teachers have existing pedagogical content knowledge, and therefore, ICT needs to be introduced in specific ways within specific content which support learning outcome of students.Teachers need to gain knowledge to be directly applied in the classroom.(Ertmer & Ottenbreit-Leftwich, 2010) Some of the teachers could not even express what kinds of training they would need, probably indicating they would need fundamental experiences of subject-and contentspecific ICT integration to gain more TPK and TCK needed to start building up their own TPCK.As Voogt (2010) observed subject-specific ICT training increased ICT integration and it is a good start for developing teachers' own TPCK.
Nonetheless, chemistry teachers' pedagogical activity in the classroom needs to be investigated more detailed to gain more accurate and complete information of current situation of teachers' ICT usage and TPCK.ICT-training was found to increase positive beliefs of ICT.The need for support and training of chemistry teachers were similar to the other teachers.Chemistry teachers need ICT-training in collaboration to other teachers from the student-centered, TPK and TCK points of view to bridge all these components of knowledge to acquire their own TPCK.
The purpose of this paper is to show current knowledge of Finnish chemistry teachers' ICT skills and beliefs in comparison to other science teachers.The survey conducted included five sections which were demographical information, technological knowledge, ICT beliefs and self-efficacy, school's climate and barriers, need for in-service training and support for ICT-integration.The data was gathered from a sample of 190 school teachers from primary to general upper secondary sc hools .The sa mple was 137 fe male and 53 ma le teachers of whic h chemistry teachers were 68 and 20, respectively.The largest age group was the age of 41-50 year.Teaching experience of over 20 years was the most common.Most of the teachers (n = 86) taught in secondary schools, 53 in primary schools, 66 in general upper secondary schools, of which two taught both youth and adults, and three only adults.Similarly, 20 teachers taught chemistry in primary school, 42 in secondary school, 19 in general upper secondary school for youth and one in general upper secondary school for youth and adults.

. Optionally, teachers were able to add other barriers in the open-ended question.The qualitative responses were in line with the quantitative items.Lack of time, rush at work", "Courses full of contents", "Time, students cannot use devices, not enough time…", "No time for learning how to use hardware/software".
""No proper hardware at home, No WLAN, no smart board, technical problems, frustrating!""Lack of hardware" "Internet connections weak, slow, no connections…, Slow computers, Software not working" "Devices do not communicate", "Slowness of Internet and opening software" Furthermore, lack of appropriate software or materials (3.5 and 3.5) and instructional programs and course content (3.5 and 3.6) were significant barriers.Additionally, lack of inservice training (3.4 and 3.5) and lack of technical support (3.6 and 3.5) were regarded as insufficient.Cronbach's alpha was 0.789."Lack of knowledge and skills how to integrate ICT in learning", "Lack of good ideas", "Students incapable to utilize computers in learning purposes", "Software not suitable for all subjects (such as in mathematics)", "Lack of material", "Lack of training", "Lack of skills and knowledge", "Lack of motivation", "I am too lazy", "I'm not active", "I'm too slow to learn and I forget soon what I've learnt", "Slowness of technical help"
