TPACK development in teacher design teams: assessing the perceived and observed teachers' knowledge

  1. 1. TPACK development in teacher design teams:Assessing the teachers’ perceived and observed knowledge Ayoub Kafyulilo, Dar es salaam University College of Education, Petra Fisser and Joke Voogt University of Twente.
  2. 2. Introduction This study was conducted with the in-service science teachers in Tanzania. It adopted design teams as professional development arrangement to develop teachers’ technology integration knowledge and skills. TPACK was used as a framework for describing the teachers’ knowledge requirements for integrating technology in science teaching
  3. 3. The Intervention The study comprised of four intervention activities  The workshop  Lesson design in design teams  Lesson implementation in the classroom  Mostly a projector and a laptop were used in teaching  Reflection with peers (peer appraisal)
  4. 4. Lesson design in design teams
  5. 5. An example of a classroom set up with a projector, laptopand a projection screen
  6. 6. Research questions  What is the in-service science teachers’ perceived TPACK before and after intervention?  What are the observed in-service science teachers’ TPACK before and after intervention?
  7. 7. Participants The study adopted a case study design  Design teams were study cases  Individual teachers were the units of analysis. 12 in-service science teachers participated in the study. The 12 teachers formed three design teams (each with 4 teachers)
  8. 8. Instrument Six data collection instrument were used in this study to collect self-reported and observed data. Self reported data were collected through;  TPACK survey,  Reflection survey,  Focus group discussion and  Interview Observation data were collected through;  Classroom observation checklist,  Researcher’s logbook
  9. 9. TPACK Survey (pre and post-intervention) The TPACK survey was used before and after the intervention The instrument was adopted from Schmidt et al (2009) and Graham et al (2009) and used a 5 point Likert scale The reliability was 0.93 Cronbach’s alpha
  10. 10. Observation checklist The observation checklist was administered before and during the intervention The items had a 3 point Likert scale: “No” = absence, “No/Yes” = partial existence, and “Yes” = presence of the behavior Two people rated the observation checklist and the inter-rater reliability was 0.87 Cohen Kappa.
  11. 11. The reflection survey The reflection survey was administered at the end of the intervention to assess the teachers’ opinions about learning technology in design teams The overall reliability for items related to TPACK was 0.68 Cronbach’s alpha.
  12. 12. Researcher’s logbook The researchers’ logbook was used to maintain a record of activities and events occurring during the intervention process. The researcher’s logbook was used during peer appraisal, TPACK training and lesson design. Data collected through the researchers logbook were important in describing the interventions processes.
  13. 13. Teachers’ interview The interview was administered at the end of the intervention to asses the effectiveness of design teams in teachers’ development of TPACK An example of the interview question was:  What technology integration knowledge and skills did you develop from design teams? Four randomly selected interviews out of12 interviewees were coded by a second person. The inter-coder reliability was 0.83 Cohen Kappa.
  14. 14. Focus group discussion A focus group discussion was administered at the end of the intervention An example of the question asked in FGD was:  How do you evaluate the results of your discussion in design teams; in terms of the products you made, decisions in the team, new ideas and innovations Two randomly selected FGD were coded by a second person. The inter-coder reliability was 0.92 Cohen Kappa.
  15. 15. Results: Teachers’ perceived TPACK before and after theintervention Before intervention, teachers perceived their CK, PK and PCK as high, and TK, TCK, TPK and TPCK were low. After intervention, all TPACK components were perceived high. A Wilcoxon signed ranks test for two related samples showed that TK, PK, TCK, TPK and TPACK were significant at p ≤ 0.01 whereas CK and PCK were significant at p ≤ 0.05 Results from the reflection survey showed that teachers’ developed TPACK through their participation in design teams.
  16. 16. Results (Teachers’ observed TPACK) Findings from teachers observation showed a significant difference between pre- and post- intervention results. Pre-intervention results showed a low teachers’ TK, TCK, TPK, and TPACK (M < 1.5, SD ≤ 0.17) in a three points Likert scale However, in the post-intervention results, all TPACK components were high (P ≤ 0.05).
  17. 17. Conclusions The triangulation of the findings from self-reported and observed data showed;  A limited teachers’ TK, TPK, TCK and TPACK before intervention,  After intervention all the TPACK components were high In this study, self-reported data comply with the observed data This differs from the findings of Alayyar (2011) and Kafyulilo et al (2011) which showed a difference between the observed and perceived TPACK
  18. 18. Conclusions Probably this has something to do with  The instrument,  The culture and  The level of the teachers. Findings from both observed and self-reported data indicate that teachers’ PK, CK and PCK were high before and after intervention. This may suggest that in the context of Tanzania, technology integration efforts need to focus more on technology related components of TPACK rather than the whole TPACK.
