Why can’t students see the correct answer when they get a question wrong?

Each question in Sparx has a small number of variations so if students could see the answers, eventually they would have seen all available examples and could start guessing or predicting the correct answers. This would in turn affect our assessment of their ability and level, resulting in diluted personalised homework. 

Instead of showing answers, we give students a second & third chance

One question with three variants

 

• After an incorrect attempt, students are given a Second & third Chance where they have another attempt at exactly the same question
• This gives students the opportunity to correct and learn from their mistakes and also encourages students to write workings
• After an additional incorrect attempt, students will then receive a slightly different variant
