I had decided to conduct such a lesson as I realised that the students were not reading the problem sum questions carefully, not thinking through what the questions were about and were only focused in wanting to solve the questions head on. Many a times, this “bull-dozing” approach led to frustration as the students would not be able to solve the questions.

Hence, to eliminate the “rush” to solve the questions, I changed the learning outcomes to be identifying what the question types were and state the reasons for their decisions. It is only after they have successfully done so that they are asked to solve the questions numerically.

On the whole, I felt that the lesson went well, albeit some initial technical challenges. Most of the students were able to read the questions more in depth as they were not pressured into having to solve the questions. The collaborative approach in discussing how to word their reasons with their team mates also facilitated learning in their Zone of Proximal Development as each built on and/or challenged each others’ responses respectfully.

The use of ICT was an enabler for DI as each group was able to progress at their own pace. However, there were also limitations to the use of Google Forms as the students were quick to “outsmart” the form by making guesses in the MCQ portions to derive the answers before deriving their reasonings. It is certainly something I would work to improve on.

The use of authentic text and situations helped to engage the students and increased their involvement and engagement to the learning.

Most of them enjoyed the lesson and I will endeavour to continue working on planning such lessons for them.

How do you check their written explanation and intervene? What if they put wrong or funny answer? What would you do? Sorry I didn’t stay till the end to see…

Probably give them the group names as they took some time to create it. I wish I could stay longer!!

I like how the lesson is crafted to give students the motivation to learn and still have the element of fun. The questions are also created to align with the solving the criminals theme to make it as authentic as possible. I like that Marcus enforced that students must give their reasons for the choices to make them think abt their reasoning. The devices will also given out smoothly so it shows that students know what to do in a tech lesson.

I also like the part where you set the ground rules first before you zoomed into the activities. This gives the students an idea of what is expected of them from the lesson.

Can also tell that this is not the first time the children are doing ICT-related activities as they know how to collect the devices in an orderly manner.

I like how you started the lesson with the class. You managed to capture their attention and children love stories so it helps them to follow the lesson by giving them a 'real-life' scenario.

Great job at identifying the 4 crimes (types of problem sums, e.g. Before-After, Constant Difference, Repeated Identity and Total Unchanged). and the 4 suspects associated with them! Now, go on to solve each of the questions to close each case!

Dear all,

Here is the deck of slides which I will be using to facilitate the lesson.
