Abstract

The role of teachers in students' academic achievements in schools is key to the students' success and the evaluation of teachers in Sierra Leone. The objectives of this research are 1) Evaluate the contributions made by teachers towards students' performance in the NPSE at selected primary schools in Yoni Mamaila Chiefdom; 2) Identify the factors leading to the success or failure of students in the NPSE; 3) Uncover the obstacles limiting students' performance in schools. This study utilizes a mixed-method approach and a descriptive survey with a cross-sectional design. Data collection techniques included interviews, questionnaires, and documentation. The study was conducted in 4 selected schools with a research population of 200 individuals. The sampling technique used was purposive sampling, resulting in 60 respondents. The collected data were analyzed using descriptive data analysis. From the data analysis results, the conclusions drawn were 1) Teachers play an integral role in enhancing students' academic performance in the National Primary School Examination (NPSE); 2) Factors leading to the success or failure of students in the NPSE include the economic background of the family, the level of family education, and teachers' commitment to teaching; 3) There is a lack of support from stakeholders to assist students in obtaining necessary information. This study's findings indicate that learning based on dual representation significantly influences middle school students' academic achievements in single-variable linear equations.

Abstract

Mathematical problem-solving skills are essential for students to succeed in the 21st century, yet many struggle to apply mathematical concepts in real-life situations. This research addresses the need for innovative learning media by developing Statblithz Game, an educational game designed to train and enhance students’ mathematical problem-solving abilities. The study employed a Research and Development approach using the ADDIE model, involving stages of analysis, design, development, implementation, and evaluation. Participants included middle school students who engaged with the prototype and provided feedback through questionnaires, expert validations, and pre- and post-tests measuring problem-solving performance. The results indicated that Statblithz Game is highly feasible, with expert validation scores averaging 89%. Moreover, students’ problem-solving test scores improved by an average of 25% after using the game. In conclusion, the Statblithz Game effectively enhances mathematical problem-solving skills and offers an engaging alternative to traditional mathematics instruction. The impact of this research lies in providing educators with an innovative and interactive tool that can foster critical thinking and improve student learning outcomes in mathematics.
