Research shows that early childhood interventions with fidelity to Montessori model generate learner’s outcomes that outperform the traditional model. The evidence is confirmed in developed and in developing countries. This formative evaluation reports the results of a Montessori model in implementation in township of Mfuleni, located in Cape Town, South Africa. Providing insights into the functioning of the programme, the evaluation confirms that the roll out of the Montessori model is still underway which may explain the reason of the learners not outperforming the comparison group.

Denna studie utgår från en tes om framgångsrik undervisning som baseras på Hatties m.fl. (2017) och Grevholms (2012) forskning. Uppsatsen är en jämförande studie som utgår från tre undervisningsmodeller i matematik, traditionell undervisningsmodell, montessorimodellen och singaporemodellen. Fokus är på matematikundervisning i årskurs 1-3, svensk skola. Studien omfattar dels en mindre litteraturstudie, dels en intervjustudie med tre lärare som arbetar enligt de tre modellerna. Jag utgår från ett sociokulturellt perspektiv på lärande, undervisning och kunskap. Analyserna baseras på en riktad kvalitativ innehållsanalys. Resultatet visar på för och nackdelar med de tre undervisningsmodellerna och hur väl de uppfyller kraven enligt tesen för en framgångsrik undervisning. I resultatet tydliggörs genom lärarnas utsagor problematiken med de olika undervisningsmodellerna. / The proposal in this study define successful teaching from Hattie et al. (2017) and Grevholm (2012) research results. This is a comparative study with three teaching models in mathematics, Traditional model, Montessori model and Singapore model. The focus is on mathematics teaching in primary school, in Sweden.  The study embrace a minor literature study and an interview study with three teachers, who work according the three models in their teaching. I use a socio-cultural perspective on learning, teaching and knowledge. A directed qualitative content analyze is used to analyze both the literature and the interviews.  The results show the pros and cons of the three teaching models, according to the requirements of the proposed ideas of successful teaching. The results of the teachers´ statements clarify and problematize the differences between the three educational models in practice.
