Abstract

Solving mathematical word problems is a big challenge for many learners. One reason for the challenge could be the use of inappropriate strategies in solving mathematical word problems. In Namibia, many examiners’ reports show that learners do not attempt algebraic word problems fairly in examinations. This study investigated Grade 10 learners’ strategies for solving algebraic word problems in the Ohangwena Region, Namibia. The study followed a qualitative approach. A sample of 351 Grade 10 learners from ten secondary schools participated in the study. Krulik and Rudnick’s problem-solving strategies model was adopted as the framework that guided the study. Data was collected using the Algebraic Word Problem Solving Achievement Test and analysed using content analysis. The result shows that most of the learners could not use appropriate strategies to solve the given problems. Few learners employed one or two appropriate strategies in solving the problems. The strategies used by the learners to solve the algebraic word problems in the test include Computing or Simplifying (CS); Making a Table, Chart, or List (TCL); Making a model or a diagram (MD), and Guessing, Checking, and Revising (GCR). It is recommended that teachers model different strategies for solving mathematical problems for learners while teaching mathematics. Keywords – problem-solving, problem-solving strategies, algebraic word problem.

Abstract

The problem of the study was to investigate hindrances to undergraduate students’ meaningful learning of bivariate normal distribution (BND) in a Kenyan university. The study was informed by students’ poor performances in BND. This study adopted a case study design and a qualitative research methodology. Data was collected using a questionnaire from second- and third-year undergraduate statistics students (n=175). The data was thematically tabulated and analyzed using descriptive statistics of frequencies and percentages. The study revealed various hindrances to undergraduate students’ learning of BND, which included;- inadequate background knowledge on BND, negative attitude towards BND, lack of interest on BND, inadequate learning resources on BND, inefficiency in learning long and complex statistical equations, inability to comprehend BND function, inability to derive the conditional mean and variance equations of a joint distribution, lack of an in-depth teaching of BND, few worked examples and assignments on BND etc. It is recommended that an in-depth teaching and learning of BND coupled with adequate worked examples and assignments should be embraced by utilizing university’s freely provided internet resources to bridge students’ statistical content knowledge and pedagogical knowledge gaps.Â
