Abstract
The purpose of this study was to determine the effect of the Van Hiele instructional model on students’ achievement in Circle Geometry at Daffiama Senior High School in the Daffiama-Bussie-Issa District of the Upper West Region in Ghana. The purposive and simple random sampling techniques were employed to select a sample of 75 participants for the study. The sample involved two groups: the experimental group and the control group. While teaching based on the Van Hiele model was carried out in the experimental group, teaching with the traditional method was carried out in the control group. The study employed a quasi-experimental research design. The instruments used for data collection were tests, interviews, and classroom observation. Findings from the data analysis suggested that participants were at the prerecognition level before the intervention, improved from the prerecognition level to level 2 after the intervention as the model facilitated learning. It was recommended that teachers determine the geometric thinking levels of students before instruction; the Van Hiele learning and instructional model is adopted in curriculum design and applied in the teaching of geometry and other areas of mathematics.

In the world all over, a strong culture of mathematics in a nation contributes to building a strong industrial culture
As part of the current government efforts to address the situation, the National Curriculum Framework (NCF) was released by the National Council for Curriculum & Assessment (NaCCA) in May 2018. is was part of the process where the present school curriculum is being reviewed to respond to a national priority of shifting the structure and content of the educational system from merely passing examinations to building character, nurturing values, and raising literate, confident, and engaged citizens who can think critically according to National Curriculum Framework [4]
E population consists of students of Daffiama Senior High School in the Daffiama-Bussie-Issa district of the Upper West region of Ghana. e school was chosen because students from different kinds of cultures and backgrounds made up the population of the school. e second-year students of Daffiama Senior High School were sampled for the study because students at this level are assumed to have acquired the requisite knowledge to learn circle geometry. is was a form of “convenience” sample
Summary
In the world all over, a strong culture of mathematics in a nation contributes to building a strong industrial culture. For this reason and many more, mathematics is made a compulsory subject from preschool to secondary level in almost every country in the world. E move was part of efforts by the government to develop a strong human resource for the nation’s economic growth. This move has not been without challenges.
