Solving Problems One Step at a Time

The Science teachers at Temasek Junior College have put great effort and thought into designing their pedagogy and curriculum. They believe this has helped their students to be better thinkers and learners.

When the first batch of students from Temasek Junior College‘s (TJC) Integrated Programme (IP) took their first Science common test, together with their first-year JC counterparts in the mainstream, they didn’t do so well.

It wasn’t that they didn’t have the requisite knowledge. It was simply because they had not taken a pen-and-paper exam in a while. In fact, they had not used a Science textbook for some time either.

But it wasn’t long before they were outperforming their peers. Their teachers believe it was because these students were taught to THINK differently.

THINK in Progress

The THINK© cycle was introduced as a key pedagogy for Science when the IP began in 2005.

“The THINK cycle is a rojak (or blend) of problem-based learning, inquiry-based learning, project-based learning and more,” explains Mr Simon Foo, Head of TJC’s Science Department.

The THINK cycle begins with a trigger, usually a case study involving a problem or an inquiry. Students drive the process by exploring and discovering the gaps in their knowledge. They gather and interpret the data on their own, and then come together to build on each other’s findings and hypotheses.

Teachers take a step back and provide guidance when needed. “We are there as facilitators and not dispensers of knowledge,” explains Simon. “Most of the time we answer their questions with questions pointing them in a certain direction or to read a certain article.”

At the end of the cycle, students present their work to their other classmates, in the form of a video, model or Flash animation. The challenge is to present their findings and explain the Science concepts used to solve the problem to others.

The THINK Cycle

The THINK© cycle consists of five steps – Trigger, Harness, Investigate, Network, and Know – guiding students through either a problem or an inquiry. Working in small groups, students conduct research, brainstorm, and then come up with a solution.

  • Trigger – The trigger is in the form of a problem or question that will spark students’ interest to find out more.
  • Harness – Students try to fill in their knowledge gaps by asking questions and doing research.
  • Investigate – Students check whether their speculations are correct and gather data to support their hypothesis.
  • Network – Knowledge is constructed as it is shared and interpreted together.
  • Know – Students should arrive at a solution for the given problem.

 

TJC is now working with Gongshang Primary School to see how the model can be applied at the primary school level.

Getting Used to THINKing

As with all things new, the THINK cycle needed some getting used to. Mrs Joyce Teo, Head of IP Science, notes that students often feel insecure when they first join the IP. They are more accustomed to structured tasks and pen-and-paper assessments.

Teachers, too, especially the newer ones, sometimes struggle because their own learning experiences were mostly teacher-centred. But everyone usually gets accustomed to it after a term or two, especially the students.

Through years of using and refining this process, the teachers have found that the critical approach to learning does encourage creative thinking in their students.

Joyce notes that they pick up the skills of working through the thinking process rather than expecting answers to be given. They start thinking about what can be done, how it is done, and why it is done a certain way.

“They feel it’s okay to be uncertain and to explore and to not know,” adds Simon. It helps that they also start to do better in their project assignments, and that encourages them to keep at it.

Fish Files

The Fish Files is a prime example of the THINK cycle in action. Students learn about ecology through a study of aquariums.

“We physically set up two aquariums – one is a successful one, the other a failed one,” explains Simon. “That is the trigger.”

Why aren’t the flora and fauna thriving in the failed aquarium? What went wrong? How did the fish die? These are questions that students have to answer using what they’ve learned in both Chemistry and Biology.

Working in small groups, students conduct their own experiments, test the pH level of the water in both aquariums, and also do research on the symptoms leading to the death of those fish.

Through an online platform, students share their research and opinions on the case study. This also allows teachers to participate in their discussions and guide them through their investigations.

Effectively Creative Science

At the heart of the THINK cycle is a desire to make Science learning relevant. “It’s actually very much about how Science should be learned in an authentic form, and not in terms of memorizing facts, putting them down on a piece of paper and scoring well.

This model of teaching was thus designed to help contextualize learning. “Science is not learned in silos – all of it has connections to our daily lives,” says Simon.

In the real world, they will not always get answers. They have to find it, and then decide how to share the ideas.

It also effectively develops 21st century skills such as being a more confident and self-directed learner as well as an active contributor. “The Ministry of Education encourages two elements – collaborative learning and student-directed learning,” notes Simon. “That’s very much in our THINK cycle!”

“We realize that this mode of teaching and learning does take up a bit of time, and with that it also means that the content we cover may not be as much,” notes Joyce. But the teachers at TJC have pressed on, firmly believing that the THINK cycle works, and they believe their efforts have paid off.

Simon is pleased to note that the students are clearly learning in a deeper manner. When given a problem, they are able to gather knowledge from various sources and apply it to solve the problem. “I do see a lot of transference of knowledge and thinking of other dimensions,” he says.

As Joyce notes, “In the real world, they will not always get answers. They have to find it, and then decide how to share the ideas.” For these students, they can say they know how.
