Sharing on the implementation of Major concern 1 2014-2015 Pre-lesson Tasks Mathematics Department 28-11-2014

Purposes of pre-lesson tasks in Mathematics 1. Basic Knowledge Review Brief notes or simple mathematical questions aim at recalling students’ memories of the prerequisite knowledge, formulas or mathematical terminology learnt in the junior form. e.g. Secondary 5 Variation Revision of rate, ratio & percentage

Secondary 5 S1

Purposes of pre-lesson tasks in Mathematics 2. Exploration (Arousing students 'interest) Watching TWIG film or doing inspiring activities that can motivate students to explore mathematical concepts and experience the process of constructing new knowledge such as deriving new formula on their own. e.g. Secondary 6 Summation formula of Arithmetic Sequence

Purposes of pre-lesson tasks in Maths 3. Self-directed learning Students are required to study the content in their textbook (new knowledge) on their own. Then, they will act as a teacher to teach their classmates during the lesson. e.g. Secondary 3 Hexadecimal system

Secondary 3

Example (Junior level) Level : Secondary 2 Topic: Solving simultaneous linear equations by the method of elimination Implementation: Before the lesson 1. Students are required to finish a worksheet.

Example (Junior level) 2. The questions in the worksheet guide students to acquire new techniques through step-by-step explorations. Firstly, the question involve numbers only. It is easier for students to handle. Then, the questions involve variables. Finally, students have to draw a summary of what they have acquired.

Secondary 2

Example (Junior level) Implementation: During the lesson 1. Students are asked to display their answers and report what technique they have acquired. 2. During the oral presentation, other students are invited to give comments and suggestions. The teacher also give feedback to help students identify their weaknesses and mistakes. 3. Then, students use the new technique to solve simultaneous equations.

Example (Senior level) Level : Secondary 4 Topic: Equations of straight lines Implementation: Before the lesson 1. Students were required to watch two videos (3 mins + 10 mins) and finished a pre-lesson worksheet before lesson.

Exemplar 2 Implementation: During the lesson 1. Students were asked to complete a pre-study quiz 2. Teachers check whether students can applied the formula learnt in the pres-lesson worksheets. 3. A Student were asked to present his answer to the whole class.

Evaluation Students are activated to learn the new knowledge. Students attend the lesson with questions in mind. Less-able students are better prepared for the lesson. Having a brief understanding before the start of a new topic enables student to acquire new knowledge better and faster.

Difficulties Learner diversity Some students do not do pre-lesson tasks Lazy Incapable Manageable tasks Should we teach students during lesson if they haven’t done the pre-lesson tasks?
