Diagnosing Errors in The Algorithms of Solving Linear Equation System for Selected Sample of 10th Graders in Jordan

Auther : Younes M. Alyounes

     This study tries to determine the percentage of 10th graders in solving algebraic equations. It also aims at uncovering the error categories that 10th graders make and their percentage in each category in solving algebraic equations. To do so, a 13-item diagnostic test was developed. All items were open-ended and the students were asked to show all solution steps. The test was administered on a sample of 138 10th graders (70 males and 68 females) who were given enough time to finish the test. Students papers were corrected and the percentage of students weak in solving algebraic equation were calculated. Their percentage was (63%) and the Chi-square value was found statistically significant (chi^2= 9.39) at (alpha =. 01). After that, students errors were categorized and the percentage of their errors, for each category, were calculated. Student errors were classified into five main categories. They are conceptual errors, errors relevant to generalizations, errors relevant to procedures, difficulties in mathematics language, and errors relevant to lack of concentration (carelessness errors). Recommendations were made for teachers, students, curriculum developers and researchers.
