Chalkboard skills for effective teaching
- 1. CHALKBOARD – SKILLS FOR EFFECTIVE TEACHING AND LEARNING PROF.B.V.APPARAO NIT WARANGAL
- 2. Discovery of Black Board • James Pillans (1800 ) Head master in a school in Edinburg, Scotland • George Baron, Maths Teacher USA(1801)
- 3. Blackboard –The best contributor to learning “The inventor or introducer of the blackboard deserves to be ranked among the best contributors to learning, if not among the best benefactors of mankind.” -- Josiah Bumstead, 1841
- 4. Why is the Chalkboard effective? • It is a medium of interaction between teacher & students. It is a Teaching Aid • Ease of presentation • Self Pacing possible • Allows flexibility and spontaneity • Student Involvement • Organization of the lesson, Building up the story
- 5. • Notes - taking by the students • To develop students’ drawing skills • Lesson Coherence • Helps structured Teaching Style • Gain attention and interest of students in the subject • Retention of the subject • Helps in classroom management
- 6. Examples from different subjects • Maths: Working out problems step by step by active participation of students • Engineering Graphics: Explain the skills of engineering drawing • Electrical engineering: Drawing electrical circuits • Chemical Engineering and Biotechnology: Drawing flow charts of processes • Computer Programing: Teaching programming languages, Theory of computation
- 7. • Physics and many other subjects: Derivations • Chemistry: Stoichiometry, chemical equations, chemical formulae, structures, Mechanism of reactions • English: Grammar, New vocabulary
- 8. Some reasons to use the Chalkboard: • To plan, control and pace the interaction and discussion • As a work space for brain storming, problem solving, practice and discussion • For visual presentation of the course material • To compare and contrast different theories and analyses • To consolidate results or conclusions from discussion
- 9. Types of matter to be written on the Chalkboard: • Outline of the plan for the day’s class • New terms and definitions • Statements of hypotheses • Examples(names), diagrams, graphs, tables • Formulae, equations, derivations • Working out the solutions to problems • Concepts and ideas that advance the discussion
- 10. Planning the use of chalkboard in the class • Erase the chalkboard completely at the start of the class. • Use zones on the board for specific purposes For eg; Left edge of the board for the outline of the class plan Right edge for writing brief statements of conclusions Middle zone (large area) for developing the unknown lesson content based on the interaction in the class • Use zones consistently in a class and erase the matter zone wise • Think about when you will erase a particular zone. Don’t erase a zone if you will need the material in that zone again later • Plan before hand when and where you will write a particular material
- 11. Mechanics of using the chalkboard • Write legibly with letter size large enough to be read clearly by any student sitting in the farthest bench in the class • Posture important: Stand at 45 degrees to the board As you write, students must be able to note down Move your body, as you write Bend at knees when writing low • Coloured Chalks: On a green glass chalkboard, yellow chalks are good for headings. White chalks are good for all other material. Don’t use more than three colours • Underlining: Underline main headings and sub headings
- 12. Mechanics Rectangular boxes: Put most important conclusions, final equation of a derivation rectangular boxes, definitions in rectangular boxes. Students will find it easy to understand when they refer to the notes during revision later. Abbreviations: use abbreviations of names only after you introduced them in full form Writing and explanation must go hand in hand
- 13. Tools for drawing shapes ,figures etc Ruler, Compass and other devices to draw drawings, different shapes, graphs, diagrams etc. when necessary Organize and practice using chalkboard in advance Use a pointer while discussing the chalkboard material Present the material simply and briefly
- 14. Quality of Chalks and how to use them Dust less chalks Holding the chalks Enough chalks in the class room including colored ones Quality of dusters
- 15. Chalkboard set-up • Chalkboard size: • Sliding Boards: • Distance between Chalkboard and first row: • Periodical painting of the board:
- 16. How not to use the Chalkboard • Do not write large procedures or descriptions • Do not write irrelevant information • Do not over write • Do not scribble • Do not stand in front of the material what you just wrote • Do not erase the material on the board too soon after you wrote
