 Abstract

Air and Water are essential components for living beings. The conventional method of testing water and air quality is to gather samples manually and send to the lab for test and analysis. This method is time-consuming, wastage of manpower, and not economical. Present work describes the design and development of Water and Air Quality Monitoring system. The water and air quality measuring system that we have implemented checks the quality of water and air in real time through various sensors (one for each parameter: pH, TDS, temperature, turbidity, MQ135, Dust sensor) using the IoT concept. The Wi-Fi module in the system transfers data collected by the sensors to the microcontroller and transfers the data to the smartphone/PC using the ThinkSpeak API. In addition, an alert system is deployed to alert PCB officials if water and air quality go down. This system can keep a strict check on the pollution of water and air.

 Abstract

The communicative language teaching (CLT) approach emphasizes real-life communication and interaction in language learning, but its implementation in classrooms often encounters various challenges. This abstract highlights some of the key challenges faced in communicative language classes and proposes remedies to address these issues for a more effective language learning experience. Students may not have sufficient exposure to authentic language use outside the classroom, hindering their ability to apply language skills in real-life situations. Integrate technology, authentic materials, and real-world tasks into the curriculum to expose students to genuine language use. Encourage language immersion through activities such as language exchanges, cultural events, and online language communities. Traditional assessment methods may not effectively measure communicative competence, leading to a disconnect between teaching goals and evaluation criteria. Implement a variety of assessment tools, such as performance-based assessments, portfolios, and self-assessments, to evaluate students' communicative abilities. Emphasize formative assessments that focus on continuous improvement and feedback. Managing communicative activities becomes challenging in large classes, limiting individualized attention and meaningful interaction. Foster student collaboration through group work and pair activities. Use technology to facilitate online discussions and collaborative projects. Employ teaching assistants or peer-assisted learning strategies to provide additional support.
