“…The findings were also in consonance with the findings of Luketero and Kangangi (2019), Kapur (2018), Olufemi, Adediran and Oyediran (2018) who maintained that: teachers factors (such as teachers' PCK, knowledge of students' conception (that is, motivating students regularly), knowledge of educational contexts); school factors (such as the availability of school resources and class size) and students factors (that is, the attitude of students, indecent dressing and poverty) were the fundamental factors that influenced students' achievement in schools. These findings were equally supported by Nkom, (2008); Schug, Dieterle, and Clark (2009); Wemnje, (2013); Akuro, (2015); Alobwede, (2015) as well as Kola and Sunday (2015) findings on teachers' knowledge which accentuated that the several key elements of PCK were the root behind successful instruction in core subject areas.…”
