出版社：The International Institute for Science, Technology and Education (IISTE)
摘要：The aim of the study was to assess and establish learners’ misconception and inability to apply simplification of algebraic expressions and solving linear equations in Chilanga District. The study sought to determine the possible causes of learners’ inability to apply simplification of algebraic expressions and solving linear equations in relation to identification of inverses in senior secondary school. A case study research design was employed to achieve the objectives and a sample of 100 grade 11 learners and 10 mathematics teachers from school A and school B participated in the study. To collect data the instruments used were a questionnaire, tests and interviews. Quantitative data was analyzed using an Excel statistical package while the reliability of the instruments was tested using Cronbach’s alpha (α). The main findings the research study established are that learners misused and misapplied addition, subtraction, multiplication and division when simplifying algebraic expressions and forming linear equations. Learners also met challenges when it came to solving linear equations because they lacked knowledge of additive and multiplicative inverses. The main conclusions drawn from this research study are that misconceptions learners experience in algebra are attributed to the lack of conceptual knowledge and understanding and these misconceptions occurred frequently in learners..
