In the field of education, globally, teachers are recognised as important contributors in shaping learners’ interaction in a cooperative learning environment through effective lesson planning. There is a plethora of research conducted internally on lesson planning, as a critical instructional competency for good teaching and as a purposeful activity that precedes the delivery of instruction. This study aimed to explore Life Orientation teachers’ lesson planning incorporating a cooperative teaching and learning approach in secondary schools in De Aar, South Africa. The researchers adopted a mixed-methods phenomenological research design. Seven Grade 10 Life Orientation teachers were purposely selected to collect semi-structured interviews data, non-participatory observation, and document analysis. Data were analysed using inductive thematic analysis and supported with the literature review and the theory underpinning this study. This paper suggests an enactment between teachers’ subject and pedagogical content knowledge and instructional material. Lastly, it is also evident that many teachers lack knowledge, insufficient instructional resources, and an understanding of effective lesson planning to implement a cooperative teaching approach.

Internal and external assessment instruments, such as the Vanuatu Standard Test of Achievements (VANSTA) and the Pacific Island Literacy and Numeracy Assessment (PILNA), reveal that mathematics achievements in the Republic of Vanuatu remain below the minimum standard. This study drew on the constructivist grounded theory approach to explore teachers' perspectives of the learning and teaching processes in mathematics education in the Republic of Vanuatu. Specifically, the focus was on the ‘I do-we do-you do’ approach of teaching, which is common in mathematics education in the country. Teachers' opinions about the current situation of mathematics education and possibilities for improving it were extracted using semi-structured interviews with 22 teachers from two randomly selected urban schools. Based on the constructivist grounded theory analysis, four major interlink themes were found. Overall, the findings show that mathematics achievements in the country can be improved through proven discovery-learning strategies for stimulating students' mathematical thinking in the 21st century, such as the ‘try-understand-apply-mastered’ (TUAM) discovery learning process.
