This study aims to formal inquiry to discover and examine the facts of the usage of Augmented Reality (AR) in learning science subjects. The research presented an overview of AR Technology in education using the Constructivist Learning Theory (CLT) model along with educational strategies and also provided an analysis of the results of using the AR-based model. The study was conducted students of four different schools of Sialkot, Pakistan in the session of 2022-2023.The study was conducted on 160 students aged 11 to 16 years from four different schools in Sialkot, Pakistan in the session of 2022-23.Students were divided into two groups of equal number of students: one control group and other one experimental group. There were 4 experimental and 4 control groups in total. This methodology has evolved in students learning through traditional method and AR-based model. Methodology used both qualitative and quantitative (mixed) approaches and data collected through pre-test & post-test. As a data collection tools were used: “Achievement Test with Open-Ended& Close-Ended Questions” for result collection, “Attitude Scale Test towards AR Technology” for student’s mentality level checking and “Semi-Structured Interview Form” for opinions. An attitude scale test was initially conducted, followed by a comparative study using both traditional classroom methods and an AR based model. This research explores the impact of these methods on attitudes, with a focus on aligning with constructivist learning principles. A sample of the study was randomly selected 80 students out of 160 for the control group and the rest for the experimental group. After obtaining the results using the traditional methods and AR-based models, the researcher applied p-test and t-test, which showed that the learning outcomes of the students have been increased by using AR-based model. The researcher has applied HCI Heuristic Evaluation (HE) to the proposed AR model and also collected the results of semi-structured interviews, attitude scale test towards AR technology which showed that the use of AR in education has enhanced the user experience and students learning outcomes.
