Playing games is an important part of a child's cognitive and social development. Students learn more when they are allowed to play and engage in hands-on activities rather than being forced to memorize knowledge (formulas) from books. Enjoyable components must be incorporated into their classes to maintain their attention and increase their performance. The great benefits that gamification offers must be integrated into the basic level of education to limit the easily bored span. Appropriate integration of gamification into classroom activities could raise a positive effect on students’ performance and promote a positive attitude toward learning. This study could provide teachers with information and awareness on innovative instructional approaches that can boost students’ engagement, motivation, and performance while learning. It can also serve as an eye-opener for teachers in other fields of learning to explore and adopt better instructional approaches to teaching to improve student performance. Training of teachers on the use of gamification-based teaching should be integrated into our educational sector. This research was conducted to determine the influence of gamification elements on student academic achievement.

In this modern era, the electrical power system faces a shortage of fossil fuel-based energy sources. To overcome this problem, people more focus on giving towards renewable energy sources like solar energy, wind energy, and nuclear energy sources. This also can be used to overcome global warming and reduce pollution by fossil fuels. This study used a photovoltaic (PV) array to give supply to the Multilevel Inverter (MLI) with different irradiance values, which can be used for educational purposes. The sinusoidal pulse width modulation (SPWM) method is used here to control the converter. SPWM technique is the easiest technique than the other types of pulse width modulation (PWM) technique. In this technique the switching loss is very low, therefore efficiency is high. After the simulation, the output waveforms are similar to the sinusoidal waveform for the resistive load. In this topology, after simulation, the total harmonic distortion (THD) contents were found to be less by using an LC filter. The model is simulated in MATLAB/Simulink. The analysis of output voltage waveforms is discussed with the reduced THD.
