Evaluating the effectiveness of Self-Directed Metacognitive (SDM) questioning during solving of Euclidean geometry problems by grade 11 learners
(2017) Madzore, Edwin
This research explores the importance of Self- Directed Metacognitive questioning in the solving of Euclidean Geometry problems by grade 11 learners. A quasi-experiment was carried out at an urban school with fifty eleventh grade learners. Most researches in Mathematics Education aimed at unveiling socio-economic factors that hamper mathematics learning. In this research, I suggested that strategies that target the learners' metacognitive development can assist in addressing poor mathematics achievement. Metacognition (thinking about thinking) makes learners drivers of their own cognitive processes so that they can become better doers of the subject The research answered the question: Does teaching of metacognition to Further Education and Training (FET) learners help them to become better learners of Euclidian Geometry? This question was broken down into the following sub-questions: What is the effect of the use of Self -Directed Metacognitive (SDM) questions on the confidence level and preparedness of learners in the learning of Euclidean Geometry? To what extent does purposeful teaching and learning of metacognitive skills yield positive results in answering Euclidean Geometry questions? Metacognitive skills helped learners to perform better in problem-solving. This result agrees with previous researchers and is also consistent with the results of earlier investigations showing that achievement in mathematics can be raised through instruction enriched with metacognitive activity. Where previous research dealt with metacognitive training in an implicit manner this research on metacognitive training was done explicitly and it resulted in improved mathematics performance by learners.
The Impact of learning mathematical vocabulary of functions using the frayer model on conceptual understanding and mathematical performance of Grade 11 learner
(2023-03) Madzore, Edwin
This study investigated the impact of integrating the learning of mathematical vocabulary and the learning of mathematical content by Grade 11 learners in secondary schools in Gauteng province, South Africa. The main research question of the study is: what affordances does the integration of focused vocabulary and mathematical content learning provide for conceptual understanding and performance in mathematics? A cohort of Grade 11 learners (n=157) took part in this quasi-experimental study with control (n=83) and experimental (n=74). The experimental group was exposed to explicit learning of mathematical vocabulary using the Frayer model, while the control group used any other method preferred by their teachers. During the posttest, learners from the experimental group outperformed their counterparts in associating mathematical vocabulary with a mathematical graph. The study showed that the Frayer model is an effective strategy for learning mathematical vocabulary. When learners learnt mathematical vocabulary using the Frayer model, they mastered more vocabulary than their peers in the control group and this translated into improved conceptual understanding and performance in mathematics. There is a positive moderate correlation (r = 0.61) between the quantity of correct mathematical vocabulary that learners know and the marks those learners obtain in a mathematics test. The study further showed that it is possible to adopt Content and Language Integrated Learning (CLIL) in South African Schools
