Oral Reporting

This DI lesson is part of the Year 1 Oral Reporting Unit and aims to equip students with skills to organise information in an oral report. The pre-assessment task requires students to take down notes while listening to recordings of interviews and present them using a mind-map. Based on the pre-assessment data, students are grouped according to their level of readiness, and assigned activities tiered to match the level of challenge suited for each group. Through instruction differentiated through Process and Product, students are guided towards understanding that effective organisation of information facilitates audience’s comprehension and sustains their interest.

Teaching softball in a differentiated classroom

Fielders’ choice: A student-Centered Approach
How can catching or stopping the ball at your comfortably help you be effective in Softball? Quality learning involves the teacher differentiating instruction to meet the needs, interests and abilities of each individual student. That differentiation might involve the teacher adapting/modifying the content, process and/ or environment. The goal is to have students participate in activities where all students can learn and be successful in the sport.

A Carbon-Neutral Society

The increasing use of fossil fuels and high carbon and greenhouse gas emisisons has inevitably led to a wide range of impacts. The lesson will focus on the need for coutries to go carbon-neutral. Critical thinking strategies will be used as teaching-learning tools to discuss complex and controversial issues related to issues of climate change and the quality of life by working collaboratively and sharing with the class an article analysis of their choice. Case studies such as how feasible is it for Singapore to go carbon neutral will also be discussed.

Science - Physics

Current Electricity

The lesson uses an inquiry-based approach using a model to account for the behavior of simple circuits in which the brightness of bulb can be used as in indicator of the amount of current though the bulb. This model is extended to include the concept of potential difference. We will also be use visible thinking routines to stimulate further Scientific thinking in students.

Aesthetics (D&T)


Students will learn how to use sensors to trigger outputs such as the LED, piezo buzzer and motor. They will work in pairs, learning at their own pace, using an e-book as the learning resource. The e-book is designed in such a way that students who have prior knowledge of the technology could proceed quickly to the more complex arduino circuits while students who need more help will be supported by step-by-step instructions on videos. By completing the learning tasks in the e-book, students will learn about the if-else programming structure and the concept of "threshold value", which will trigger an output when it is reached.

Cassandra Hii

Science - Biology

Monohybrid Inheritance

Students will be able to learn and solve problems in monohybrid inheritance through the use of a problem-based learning (PBL) package. This PBL package will allow for self-directed and collaborative learning. Through the activity, students will also be able to understand the concepts through experiential learning and be able to apply the concept in genetics.

Authoritarian Regimes -
Cultural Revolution
in Communist China

(Potential) Appeal of Extremist Ideas- The lesson is on the Cultural Revolution in China (1966-76). Students would be able to use Paul and Elder's Elements of Reasoning as a metacognitive tool to examine the (potential) appeal to extremism. This would be linked to contemporary appeals to extremism through a simple case study of how religious "fundamentalists" continue to have broad support in areas under their control.

Teaching badminton in a
Differentiated Classroom

Structured small-sided activities as platforms for students to explore the forehand overhead clear stroke with good trajectory of the shuttlecock to get the shuttlecock to the rear of the court. How do I contact the shuttle, and how do I project the shuttle to where I want it to go? Using the net/barrier games concepts approach and with the modification of the equipment, rules or boundaries, the Differentiated Instruction aporach will be used to help weaker students and also further stretch better students in this lesson of Overhead Clear skill to achieve the lesson objectives.

Asmizar bin Abu

Humanities - History

The Cold War in Europe

The lesson will be on the origins of Cold War in Europe. Students will be given two groups of sources that present contrasting opinions on whether the Cold War was sparked by ideological differences or geopolitical concerns. The Wheel of Reasoning will be the Critical Thinking Model used to examine the sources. Based on this strategy, students will then uncover the probable reasons behind the Cold War conflict that emerged after the end of the Second World War.

Establishing a Voice in Writing

In this lesson, students will be differentiated based on readiness, with groups taking on different text-examination activities of varying complexities- all of which will culminate in recognising multiple ways that writers use to create a personal voice in their writing. Such might include the choice of words, or sentence structures that can affect the mood or rhythm of a text. Hence, through this main activity, students will be led to discover the effect behind using such methods and how they can thereafter apply these skills to their own writing of Personal Essays.

Benedict Chua

Aesthetics (Music)


In this lesson, students' interest would be heighten by the choice of what a particular sound/music could mean, as opposed to what it actually means. They will be working in pairs to think creatively about the author's choice of sound (or even silence - as they can sometimes be potent in meaning too). Students will also assess the basic principles of musical representation through devices such as onomatopoeia and metonymy, and at the same time assess their efficacy in a local musical soundscape.

Short Story

This lesson deals mainly with the concept of family relationships and values.  The lesson objectives are to create an opportunity to learn their mother tongue language on a more advanced level through short story and to develop analytical thinking. A strategy called the ‘Hot Seat’ technique will be used to deliver the lesson.   During lesson time while some students are role-playing as characters from the stories, others will be allowed to frame their own questions and pose them to the students playing the various roles. Opportunity will be given to all the ‘characters’ to response. Through this strategy, students can compare their own perspectives with others so as to have a better understanding of the concept.

Reading through a Critical Lens

This objective of this lesson is for students to apply a particular critical lens to the reading of a short story. This lesson is part of a series of lessons which introduces Literary Theory to the Raffles Academy Literature students. In this series of lessons, students would have been introduced to Marxist Literary Theory and Psychoanalytical Literary Theory. After the introductory lessons on Literary Theory, students will then be asked to apply the critical lens to a short story. In this Open Classroom lesson, students will be asked to analyse Shirley Lim's "Mr Tang's Girls" using the psychoanalytic lens.

Application of Differentiation:
Related rate of change

A inquiry-based approach is used for students to extend the solution to a two-variable problem to a three-variable problem. The instructional process involves the use of a real-world problem (1) for teacher to share the lesson objectives, (2) for students to practise applying Polya’s problem-solving strategies, and (3) for providing opportunities to move from problem solving to problem posing.
