Learn Math with Us! Solve Word Problems Using Unchanged Models
Model drawing has been taught in schools as it has shown to help students visualise word problems and understand them better. Model drawing has also aided many students in solving complex word problems that would otherwise have been even more time-consuming without constructing models.
One of the commonly seen heuristic skills is solving word problems using Total Unchanged Models.
Here are some examples that represent this heuristic skill.
Learn Chemistry with Us! Chemical Bonding
Many Chemistry students have shared with us that they do not understand the difference between the ‘types of chemical bonding’ and ‘types of chemical structures’. Past Year Examination Papers have shown that this is one of the most commonly tested topics and many students still find it challenging to approach despite much practice. Marks are often lost due to the wrong use of keywords or the lack of keywords, making it frustrating as students begin to feel like it is impossible to attain good grades in Chemistry.
That is, however, untrue.
Let’s work through some common misconceptions together with some of the notes we’ve prepared for our students!
Learn Chemistry with us! Acids, Bases and Salts
Many acids and bases occur naturally in nature, such as citric acid in fruits like oranges and lemons. Similarly, many bases are found in our daily lives such as limewater. In fact, we use many of these acids in our day-to-day lives, such as vinegar or acetic acid in the kitchen, boric acid for laundry, and baking soda for the purposes of cooking.
Knowing where acids and bases come from allows you to see the big picture and relate more to the concept of reactions.
What happens when acids react with metals? Why does lead not appear to react with acid? What are the products formed each time there is an acid reaction? Let’s find out together!
Learn Primary Math with us! Solve Word Problems Using Supposition Method
At The Collective Knowledge, our students are taught heuristics skills that to solve complex word problems. Applying the right heuristics skills is crucial for students to tackle challenging questions in the most efficient way possible. Here are some word problems solved using the Supposition Method.
Learn Chemistry with Us! Chemical Bonding
Chemical Bonding is a fundamental topic in Chemistry that many students tend to neglect. It is important to have a strong foundation in this topic as students will realise that mastering this concept will help in answering questions from other topics such as Mole Calculations, Acids & Bases, Metals and more.
Here are some of the important definitions that may help students understand Chemical Bonding better.
