The Uganda National Examinations Board (UNEB) syllabus argues that at an ordinary level ("O" level), "mathematics should be visualized as a vehicle for aiding a student to think, reason and articulate logically" (Uganda National Examinations Board, 2005, p.106). Thus, mathematics is seen as not only a subject capable to develop students' skills and reasoning that are required for productive citizens but also a key to understand other subjects. With UNEB's vision, mathematics remains compulsory for all primary and secondary students in the current curriculum framework in Uganda. However, it also remains one of the worst done subjects in both the Uganda Certificate Examinations (UCE) and Uganda Advanced Certificate Examinations (UACE) (Uganda National Examinations Board, 2012). In a bid to recuperate on the mathematics achievement by students in their UCE and UACE, the government of Uganda has set up several initiatives. For example, since 2012, Uganda has been retooling teachers and sensitizing head teachers in regard to ICT teaching and equipment usage and has set up over 1027 ICT laboratories in schools and district centers across the country. While it is well documented that ICTs have the added benefit of allowing learners to discover rules and generalizations for themselves (Naidoo, 2017), learners in Uganda are still far from satisfactory of such realism.

Table 1 shows that the reviewed studies used CHAT for varying purposes. For example, Beatty and Feldman (2012) viewed teacher transformation through the lens of CHAT and thus studied teacher change and pedagogical change as in-service secondary science and mathematics teachers learned Technology-Enhanced Formative Assessment (TEFA) in the context of a multi-year professional development program, termed Teacher Learning of TEFA (TLT). Their intention was to help the teachers to learn to use TLT successfully in their classes. Meanwhile, Hardman (2015) looked at the pedagogical variations with computers in South African mathematics classrooms through analyzing CHAT. CAMI, a drill and practice mathematics software, was her center of focus as being used in the lessons. Further, Hardman (2007) employed the AT approach to surface the pedagogical activity in primary mathematics classrooms in South Africa.

For example, Beatty and Feldman (2012) had 43 participating teachers from four sites, but they did not mention how they selected these teachers and the four cites from which they were as well as the country in which the study took place. Meanwhile, Hardman (2015) conducted her study in four disadvantaged grade 6 mathematics classrooms in the Western Cape Province of South Africa; thus, her study participants were four teachers from four Khanya project schools. The Khanya project in the Western Cape Province of South Africa was a government initiative involving a number of primary and secondary schools, which aimed to promote learning by integrating the use of appropriate technology, CAMI, a math software into the curriculum process. Hardman never revealed how neither the schools nor the teachers were selected and why.

Additionally, Hardman's (2007) study sample comprised four previously disadvantaged primary schools in the Western Cape region of South Africa and, hence, four grade 6 classes with 153 children and four grade 6 mathematics teachers participated in the study. Still, the selection process of these was left to the author. While Huang and Lin (2013) collected data from 24 seventh grade Atayal students in Taiwan, Naidoo's (2017) study participants comprised of six master teachers from six different secondary schools located in KwaZulu-Natal (KZN), South Africa. However, both authors, too, did not reveal the participant selection process. Meanwhile, with anonymous participant selection procedures, Trust (2017) had 160 participants from the Edmodo Math Subject Community who participated in his study and 600 initial wall posts and 1908 replies to the posts. In the meantime, Zevenbergen and Lerman's (2007) study involved two schools, one in Queensland and another in Victoria in Australia, which were using IWBs. Across these schools, five classrooms were using IWBs.

Another case in point is Hardman (2015) who used various methods to collect data namely demographic questionnaires, interviews, classroom observations, and video data of classroom practice. However, she reported only on the video data gathered over the period of 1 year. Besides, while Hardman (2007) collected data through detailed analyses of teachers' teaching, interviews with teachers and students, and classroom observations and analysis of students' productions such as workbook or board work and further video-recorded eight lessons which served as the primary observational data set, she only examined the video data for evidence of evaluative episodes and disruptions in the pedagogical script where the teacher made visible the evaluative criteria required for students to produce a legitimate text. Of interest in the context of emerging technologies, Trust (2017) collected three sets of data through online survey responses, interviews, and discussion threads from the Edmodo Math Subject Community.

Having developed a methodology for using activity theory to investigate pedagogical practices in primary school mathematics classrooms by selecting object-oriented pedagogical activity as the unit of analysis, Hardman (2007) developed the notion of evaluative episodes as pedagogical moments in which the pedagogical object was made visible. Her findings indicated that an evaluative episode can serve as an analytical space in which the dynamism of an activity system is momentarily frozen, enabling one to model human activity in the system under investigation and, accordingly in her study, to understand pedagogy in context. By using grounded theory, theoretical and methodological approaches, Huang and Lin (2013) showed a way to address complexity in the activity of learning and its development based on recognition of central cultural factors in mathematics teaching/learning. Their analysis through this systematic network revealed the factors that influenced Atayal students' learning of mathematics under their cultural background.

Although such contradictions generate disturbances and conflicts, they are also the primary sources of change and expansive developments, hence providing innovative attempts to change the activity system. Thus, teachers should be aware that tools can limit as well as enable social interaction, so must be applied wisely and appropriately to promote the most effective learning. Further, tools like emerging technologies should be aligned with the intended goals and objectives of learning. Of import to note, there is no agreed methodology for the utilization of CHAT. Researchers are always presented with many decisions as the ensuing instant step in the operationalization of the activity system's components. Thus, reviewing how the research community has previously operationalized these components to the mathematics classroom may help to step forward the many decisions the researcher needs to make. 2351a5e196
