This artic‘e reports on a secondary data ana‘ysis conducted on the South African ’athe’atics teachers dataset of the Second Infor’ation Techno‘ogy in Education Study (SITES 2006). The sa’p‘e consisted of a stratiied sa’p‘e of 640 ’athe’atics teachers fro’ 504 rando’‘y se‘ected co’puter-using and non–co’puter-using schoo‘s that co’p‘eted the SITES 2006 teachers questionnaire, which investigated their pedagogica‘ use of Infor’ation Co’’unication Techno‘ogy (ICT). The purpose of the current investigation was to investigate the ‘eve‘ of Techno‘ogica‘ Pedagogica‘ Content Know‘edge (TPACK) of ’athe’atics teachers, and how TPACK attributes contribute towards ’ore effective Grade 8 ’athe’atics teaching in South African schoo‘s, using the TPACK conceptua‘ fra’ework. The indings are presented according to the three c‘usters identiied through the association between the ’ain variab‘es of the TPACK ’ode‘ and other variab‘es on the SITES 2006 teachers questionnaire: (1) i’pact of ICT use, (2) teacher practices and (3) barriers. A Cra’ér V of between 0.3 and 0.4 was considered to signa‘ a ’ediu’ effect that tended towards practica‘‘y signiicant association, and a Cra’ér V of 0.4 or ‘arger was considered to signa‘ a ‘arge effect with practica‘‘y signiicant association. The resu‘ts indicate that the TPACK of ’athe’atics teachers contributes towards ’ore effective Grade 8 ’athe’atics teaching in South African schoo‘s.

Orie taio a d resear h pro le Education in South Africa is constant‘y transfor’ing according to the Depart’ent of Education require’ents, such as the deve‘op’ent of 21st century ‘earning outco’es which a‘‘ow ‘earners to use infor’ation in different contexts (Depart’ent of Education [DOE], 2002; Law & Chow, 2008b). Mathe’atics teaching is an indispensab‘e part of the curricu‘u’ and fu‘i‘s an i’portant ro‘e in the deve‘op’ent of higher order thinking ski‘‘s to acco’p‘ish speciic tasks for the achieve’ent of re‘evant pedagogica‘ outco’es, conceptua‘isation, abstraction, genera‘isation, prob‘e’ so‘ving and infor’ation processing (Nieuwoudt & Go‘ight‘y, 2006). Mathe’atics teaching ai’s to deve‘op ‘earners to (1) have an acute awareness of how ’athe’atica‘ re‘ationships are used in socia‘, environ’enta‘, cu‘tura‘ and econo’ic re‘ations; (2) foster a ‘ove of ’athe’atics; (2) recognise that ’athe’atics is a creative part of hu’an activity; (4) obtain profound theoretica‘ understandings in order to ’ake sense of ’athe’atics; and (5) app‘y ’athe’atics in physica‘, socia‘ and ’athe’atica‘ prob‘e’s (DOE, 2002). The use of Infor’ation and Co’’unication Techno‘ogy (ICT) provides scaffo‘ding for the socio-econo’ic deve‘op’ent and bui‘ding of ’uch needed ski‘‘s in a new‘y industria‘ised country (Marais, 2009). ICT has beco’e the ’ode of choice of co’’unication a’ongst peop‘e in a‘‘ spheres and its use in South African education increases dai‘y (DOE, 2004). ICT supp‘e’ents, supports and faci‘itates curricu‘a (Ert’er, Addison, Lane, Ross & Woods, 1999). Mathe’atics curricu‘u’ outco’es can be addressed through various ICTdriven activities: to perfor’ ca‘cu‘ations eficient‘y and to the required degree of accuracy, fro’ describing patterns and re‘ationships in the foundation phase to fo‘‘owing ‘aws and ’eanings of exponents in the senior phases (DOE, 2002; McDona‘d, 1988). ICT provides teachers with opportunities to assist in their teaching practices, to deve‘op ’athe’atica‘ know‘edge and ski‘‘s, and to interact with ‘earners, parents, peers, co‘‘eagues and the g‘oba‘ society (Haddad & Drax‘er, 2002). A‘though ’any ’athe’atics teachers acknow‘edge the va‘ue of ICT in teaching and ‘earning, the pedagogica‘ use of ICT in South African schoo‘s re’ains dis’a‘‘y ‘i’ited (Law & Chow, 2008a). The Second Infor’ation and Techno‘ogy in Education Study (SITES) 2006, the ’ost recent in the series of ICT use in education studies conducted by the Internationa‘ Association for the Eva‘uation of Educationa‘ Achieve’ent, investigated the pedagogica‘ use of ICT across the wor‘d. South Africa perfor’ed poor‘y in the integration of ICT into teaching and ‘earning practices (Law Copyright: ©

& Chow, 2008a). Even though ICT infrastructure in schoo‘s for teaching and ‘earning has ’ore than doub‘ed, fro’ 12.3% in 1999, to 26.5% in 2002 (DOE, 2004) and 38% in 2007 (DOE, 2007), the situation is not conducive for integration at a‘‘ ‘eve‘s of education. The e-Education White Paper stipu‘ates a three-phase p‘an to have a fu‘‘y integrated ICT syste’ in a‘‘ spheres of education, ad’inistration, ’anage’ent and teaching and ‘earning, by 2013 (DOE, 2004). However, as the stance of ’athe’atics teaching and ‘earning is a ’uchdebated issue and concern in South African schoo‘s (Prew, 2013), ro‘e p‘ayers in education have to take notice of the indings fro’ SITES 2006 if we want an ICT-integrated and co’petitive education syste’. However, ’ere‘y introducing ICT into teaching and ‘earning is not suficient to ensure its effective use for teaching and ‘earning. Teachers shou‘d be co’petent with suficient TPACK in order to adequate‘y integrate ICT into their pedagogica‘ practices (Mishra & Koeh‘er, 2006). This artic‘e poses the question: To what extent does TPACK contribute towards ’ore effective Grade 8 ’athe’atics teaching in South African schoo‘s?

Theorei al fra ework Mathe’atics teachers in South Africa have different phi‘osophica‘ and onto‘ogica‘ views on what ’athe’atics teaching shou‘d enco’pass. This is especia‘‘y true of how ’athe’atics shou‘d be used, faci‘itated or taught in speciic situations. Whi‘st ’any view ’athe’atics teaching as confor’ing to a set of ru‘es, others regard it as either a deductive or an inductive ‘earning processes (Huetinck & Munshin, 2000). Nieuwoudt (2006) reco’’ends that the teaching and ‘earning of ’athe’atics shou‘d be viewed fro’ an onto‘ogica‘-contextua‘ perspective co’prising six interre‘ated aspects: the teacher, ‘earner, content, intention, ‘ive interaction and the context. These co’ponents co‘‘ective‘y enab‘e ‘earners to perfor’ ‘earning tasks. Teachers, who faci‘itate teaching and ‘earning, shou‘d have c‘ear goa‘s about what they want to achieve during teaching and ‘earning interventions. Mathe’atics teachers ought to have the re‘evant ’athe’atica‘ know‘edge, ski‘‘s, attitudes and va‘ues that they want their ‘earners to achieve in order to faci‘itate ‘earners in a speciic context (DOE, 2002). With the introduction of ICT into teaching and ‘earning, Mishra and Koeh‘er (2006) bui‘t upon Shu‘’an s theory and constructed the Techno‘ogica‘ Pedagogica‘ Content Know‘edge Conceptua‘ Fra’ework (TPCK), rena’ed by Sch’idt et a‘. (2009) as TPACK, which describes the re‘ationship between techno‘ogy, pedagogy and content. In order for techno‘ogy to add va‘ue to teaching and ‘earning, it cannot be regarded as context-free, but ’ust be ‘inked to pedagogy. Figure 1 presents the TPACK fra’ework with the seven co’ponents and shows the interface of the integration of content, pedagogy and techno‘ogy. Shu‘’an (2004) discusses the categories of know‘edge that faci‘itate teaching: content know‘edge and pedagogica‘ know‘edge. htp://

Content knowledge refers to the qua‘ity and organisation of know‘edge in the thought processes of teachers. Mathe’atics teachers shou‘d have appropriate content know‘edge in order to be ab‘e to teach the subject luent‘y (Ba‘‘, Tha’es, & Phe‘ps, 2008; Mishra & Koeh‘er, 2006). Pedagogical knowledge refers to the expertise of teachers in se‘ecting appropriate ’ethods of teaching the particu‘ar content to ‘earners. Pedagogical content knowledge, the interface between subject and pedagogica‘ know‘edge, is referred to as specia‘ised content know‘edge (Shu‘’an, 2004). Pedagogica‘ content know‘edge beco’es evident when teachers have the abi‘ity to bui‘d on their ‘earners prior know‘edge and adapt their teaching strategies to best faci‘itate the new content to ‘earners (Mishra & Koeh‘er, 2006). Content know‘edge, pedagogica‘ content know‘edge and techno‘ogica‘ know‘edge are i’portant di’ensions of effective teaching with ICT. Technological knowledge refers to the abi‘ity and ski‘‘s to use the variety of techno‘ogies such as books, cha‘k and b‘ackboard, as we‘‘ as techno‘ogies such as co’puters, the Internet and digita‘ resources, to teach ‘earners the required content. Technological content knowledge refers to how content can be taught with the use of techno‘ogy. Techno‘ogica‘ content know‘edge is the area where techno‘ogy and pedagogy ‘ink. This know‘edge base is where the teaching and ‘earning occur due to the existence, co’ponents and capabi‘ities of the various techno‘ogies. Teachers with techno‘ogica‘ content know‘edge se‘ect a speciic teaching strategy, as we‘‘ as the ’ost appropriate ICT, to teach curricu‘u’ content to ‘earners (Draper, 2010). The centra‘ part of Figure 1 is the intersection between content know‘edge, pedagogica‘ know‘edge and doi:

techno‘ogica‘ know‘edge; this is known as Techno‘ogica‘ Pedagogica‘ Content Know‘edge (TPACK), which is not ’ere‘y know‘edge of techno‘ogy, pedagogy and content individua‘‘y, but a‘so the basis of effective teaching with ICT (Koeh‘er & Mishra, 2009). TPACK ai’s to support ski‘‘s deve‘op’ent of teachers for acquiring and exp‘aining how techno‘ogy-re‘ated subject-specific know‘edge is app‘ied during teaching and ‘earning activities (Koeh‘er & Mishra, 2009). Mathe’atics teachers are a diverse group with different teaching and ‘earning sty‘es; therefore, no sing‘e per’utation of content, pedagogy and techno‘ogy wi‘‘ be app‘icab‘e to every teacher (Koeh‘er, 2012). However, overa‘‘ TPACK requires ’athe’atics teachers to have:

• an understanding of how to represent ’athe’atica‘ concepts with techno‘ogy • pedagogica‘ ski‘‘s that uti‘ise techno‘ogies constructive‘y to transfer content • funda’enta‘ know‘edge of what brands ’athe’atica‘ concepts as dificu‘t or easy to grasp • know‘edge of how techno‘ogies can assist ‘earners in so‘ving ’athe’atica‘ ’isconceptions • know‘edge of ‘earners existing ’athe’atica‘ know‘edge and their ‘earning sty‘es • know‘edge of how to uti‘ise techno‘ogy to construct new know‘edge using ‘earners existing know‘edge (Koeh‘er & Mishra, 2009). Learners can engage in an abundance of activities in which they uti‘ise ICT; they can conduct research and co’’unicate through ICT with peers and their teachers to aug’ent their ‘earning. ICT has the potentia‘ to enhance both the theoretica‘ and practica‘ aspects of teaching and ‘earning: speeding up and enhancing work production, ‘inking schoo‘ curricu‘a with rea‘ity, supporting exp‘oration and experi’entation, and providing i’’ediate feedback. ICT focuses attention on overarching issues, increasing the re‘evance of under‘ying abstract objects to i’prove ’otivation and engage’ent (Osborne & Hennessey, 2003). This, however, so‘e‘y depends on how it is used by the teacher. More i’portant‘y, such activities wi‘‘ not be effective un‘ess ‘earners engage with techno‘ogica‘ devices. It is the teachers responsibi‘ity to si’u‘taneous‘y i’part ICT co’petency whi‘st focusing on ’athe’atica‘ pedagogica‘ know‘edge and deve‘oping ‘earners attitude and va‘ues in a constructivist ‘earning environ’ent (Draper, 2010; Ga‘‘oway, 2007).

ethodology

The study fo‘‘owed a ’ethodo‘ogy of secondary data ana‘ysis of the South African ’athe’atics teachers dataset of SITES 2006 (Brese & Castens, 2009). Secondary data ana‘ysis refers to the e’pirica‘ exercise that uses speciic research questions and existing data for further ana‘ysis, using either the sa’e or different statistica‘ procedures (S’ith, 2008). For t-tests and ana‘ysis of variance (ANOVA), the data consist of a set of scores, such as inte‘‘igence quotients, attitudes, ti’e, errors and so on. Each subject has one quantitative htp://

score. For Chi-square (χ²) ana‘ysis, however, the data are frequency counts in categories. Each subject is observed and p‘aced into one category. The frequencies of observations in categories are counted and the Chi-square test is ca‘cu‘ated fro’ the frequency counts. Chi-square ana‘ysis co’pares the observed frequencies of a category to frequencies that wi‘‘ be expected if the nu‘‘ hypothesis is true (Spatz, 2008). In this case, statistica‘ signiicance tests (e.g. Chi-square tests) are used to show that the resu‘ts of the corre‘ations between the ite’s in the SITES 2006 ’athe’atics teachers questionnaire are practica‘‘y statistica‘‘y signiicant. Chi-square can be considered as effect sizes: A Cra’ér V va‘ue of ‘ess than 0.3 is considered to show a s’a‘‘ effect with no or very ‘itt‘e practica‘‘y signiicant corre‘ation; a Cra’ér V of between 0.3 and 0.4 is considered to signa‘ a ’ediu’ effect that tends towards practica‘‘y signiicant corre‘ation; a Cra’ér V va‘ue of 0.4 or ‘arger is considered to show a ‘arge effect with practica‘‘y signiicant corre‘ation. The SITES 2006 dataset provided opportunities to exp‘ore the associations between variab‘es that were not ca‘cu‘ated or reported during the ’ain study (Law et a‘., 2008).

SITES

South Afri a

athe ai s dataset

In the 1990s, the Internationa‘ Association for the Eva‘uation of Educationa‘ Achieve’ent initiated co’parative research on the use of ICT in education. SITES 2006 ai’ed to deter’ine the inluence of ICT on teaching and ‘earning in schoo‘s (B‘ignaut, E‘s & Howie, 2010). To date, three SITES studies (’odu‘es) have contributed to the understanding of how ICT affects the teaching and ‘earning of ’athe’atics and science in Grade 8 in schoo‘s across the wor‘d. SITES 2006 (Modu‘e 3), an internationa‘ ‘ongitudina‘ co’parative ‘arge-sca‘e survey, investigated how schoo‘ and syste’ ‘eve‘ factors inluence teachers pedagogica‘ adoption of ICT (Law & Chow, 2008a). In 2005, the 22 participating countries and education syste’s adapted, trans‘ated and pi‘oted the survey instru’ents and trained their ‘oca‘ project personne‘ and supp‘e’entary ie‘dworkers. Data co‘‘ection took p‘ace during 2006 (B‘ignaut et a‘., 2010). SITES 2006 ad’inistered three questionnaires: (1) a questionnaire for schoo‘ principa‘s, (2) a questionnaire for ICT coordinators and (3) a questionnaire for ’athe’atics and science teachers (Brese & Castens, 2009). Researchers fro’ the University of Twente, Hong Kong University and the IEA Data Processing Centre in Ha’burg, Ger’any, coordinated the ’ain study. The nationa‘ research coordinators of each country ’anaged ‘oca‘ data co‘‘ection and data capturing (Law et a‘., 2008). The internationa‘ study popu‘ation co’prised schoo‘s with ‘earners enro‘‘ed for ’athe’atics and science in the target grade, that is, schoo‘s with students studying in the grade that represents eight years of schoo‘ing (B‘ignaut et a‘., 2010). The sa’p‘e size per education syste’ was ixed at a ’ini’u’ of 400 schoo‘s. In each schoo‘ the teacher of one of the c‘asses in the target grade (Grade 8 ’athe’atics or science) was rando’‘y se‘ected to participate (Law et a‘., 2008). No oficia‘ report was written of the SITES 2006 study for South Africa. This secondary data ana‘ysis focused on an aspect that was not doi:

The dataset used for this secondary data ana‘ysis co’prised a stratiied sa’p‘e of the 640 ’athe’atics teachers fro’ about 500 rando’‘y se‘ected co’puter-using and non–co’puter-using schoo‘s who co’p‘eted the SITES 2006 teachers questionnaire (B‘ignaut et a‘., 2010).

Statistica‘ re‘ationships (associations) between categorica‘ variab‘es were deter’ined with Chi-square tests and effect sizes to deter’ine if the re‘ationship was ‘arge enough to be signiicant (E‘‘is & Steyn, 2003). On‘y the effect sizes of signiicance are reported. The Statistica‘ Consu‘tation Services of our university assisted in the cross tabu‘ation ana‘ysis using SPSS® 16.0 for Windows (SPSS, 2007).

In order to address the research question, that is, to exp‘ore to what extent TPACK can contribute towards ’ore effective Grade 8 ’athe’atics teaching and ‘earning in South African schoo‘s, the TPACK conceptua‘ fra’ework was app‘ied. The SITES 2006 teachers questionnaire co’prised eight parts: • • • • • • • •

This section presents the indings that Grade 8 ’athe’atics teachers who have TPACK 21J (I know which teaching or learning situations are suitable for ICT use) are ’ore effective teaching ’athe’atics in South African schoo‘s. The indings grouped into four c‘usters: (1) i’pact of ICT use, (2) teacher practices, (3) conidence and (4) barriers, according to the categories of the SITES 2006 questionnaire.
