MYP 5 Biology- DNA Extraction Lab- Varsha Kumar

Objective of the Learning Engagement: Students will be able to have hands on experiment practice on DNA extraction and use appropriate scientific terminology for communication.

Details of the Learning Engagement:

Grade 10 students got to see and hold in their hand the substance they have been studying that seems so abstract and hard to believe it even exists- The DNA!! Blueprint for an organism’s growth and development. Students were able to present their DNA extraction results and insights to the class, using appropriate scientific terminology and clear communication skills. They had to explain how DNA extraction techniques are relevant in fields such as forensic science, genetic research, and biotechnology. Most importantly, they could describe the role of detergent in breaking down cell membranes, the function of salt in precipitating DNA, and the use of alcohol to isolate DNA strands.


Impact of the engagement on students and my reflection as a teacher:

Engagement and Interest: Hands-on experiments tend to capture students' attention and interest more effectively than traditional lectures. The unique and tangible nature of the DNA extraction process, especially from a common fruit like a banana, sparked curiosity and enthusiasm among students. This experiment provided students with a concrete example of the abstract concept of DNA, helping them visualize and understand that DNA exists within living organisms.

    Nice to see students engaged in the experiment. Student's retention and critical thinking skills are always enhanced when such learning experiences are planned for them.

The magic of AI Tutor -MYP 4 Physics- Sheeba Abraham

Objective of the Learning Engagement To reinforce key Physics concepts and improve conceptual clarity by using the Toddle AI Tutor for targeted revision, personalized questioning, and instant feedback, enabling students to identify misconceptions and strengthen their understanding in preparation for assessments.   Learning Engagement: The AI tutor feature on Toddle was introduced to me by Dr. Meetu Agarwal. As the time for revision approached, I decided to utilize this tool to kickstart the revision process. Upon logging into the Create AI Tutor feature, several options were available. I chose the Mastery Builder, where I input the syllabus for the upcoming Physics assessment. The AI then generated a set of instructions along with an AI rating scale, allowing students to be placed at different levels: Beginning, Emerging, Developing, and Mastery. Once the students were assigned their respective levels, the AI guided them with progressively more challenging questions. Upon submittin...

Beyond Black and White: Teaching Moral Complexity Through All My Sons- MYP 4 English LAL- Vivek Mukherjee

Objective of the Learning Engagement:  To study the motivations behind decision making Details of the Learning Engagement: Today in my Grade 9 English class, we explored the idea of decision-making and what drives people to make the choices they do. Our focus was Joe Keller’s fateful decision to ship faulty airplane parts in Arthur Miller’s timeless play All My Sons. Students reflected on what lay behind Keller’s choice: was it mainly socio-economic pressure, or was it a result of his deeply flawed character? This sparked a lively debate in class, with many different perspectives coming to the surface. To wrap up, the students created posters that tried to justify Keller’s decision-making process from different angles.   Impact of the engagement on students and reflection as a teacher: It was inspiring to see such young learners engaging passionately with themes like war profiteering, morality, and survival under extraordinary circumstances. That’s the real magic of literature...

Bringing Stories to Life: When Reading Meets Sketching and Discussion MYP1- Mayura Tiwari

Objective of the Learning Engagement:  Response to literature Details of the Learning Engagement: This is an ongoing activity - the children take turns reading aloud. They are encouraged to respond through sketching in their notebooks what they visualise. Most of them do. In turns, those who are keen - they all are! - , come up to the board and sketch. Four children - a total of eight in two shifts - take their place at the board and sketch as the others read. I get the children to pause and we discuss important parts, making connections to real life, analysing the characters, etc. The purpose is to develop listening skills, oral skills and visualisation through reading aloud. I do stop them also to correct pronunciation, intonation, etc. I establish right at the beginning that I need to help them enhance oral skills and if it is OK with them will make corrections. I get the buy-in from all of them. Some children prefer to continue to read on their own and are allowed to do that. O...
