- The paper consists of two or more questions - The experimental skills tested will be on
1. Manipulation of apparatus * successful collection of data and observations * Nature of measurements or observations
2. Presentation of data * recording data and observations * display of calculations and reasoning * data layout
3. Analysis and evaluation * Interpretation of data or observations and identifying sorces of error * Drawing conclusions * Suggesting improvements
- There will be 2 versions of the paper - Candidates take either paper31 and paper 32
OBSERVATION AND DRAWING - often assessed through drawing, although tables of observations and comparisons may be used
EXPERIMENT
1. There need to be clear distinction between observations(results) and conclusions (deductions) 2. Observation and results are generally best presented in a table with ruled lines 3. The column headings should be included in the table if appropriate 4. Calculated values should be included in the table if appropriate 5. Conclusions and deductions are generally best presented in text
GOOD PRACTICE IN DRAWING RESULTS TABLE
1. Columns and rows should be clearly headed 2. Draw columns and rows using a ruler 3. Put units in headings not in the cells within the table 4. Numerical results should all be recorded to the same number of decimal palces eg : 17.1,19.0 not 17.1,19
GOOD PRACTICE IN GRAPH DRAWING
1. The type of graph should be appropriate for the data being displayed 2. The independent variable is on the x axis the the dependent variable on the y-axis 3. Scales are chosen to make best use the space available 4. Scales need not begin at 0 5. It should be easy to plot intermediate numbers - i.e scales should go up in 2s, 5s, or 10s and not in 3s, 7s 6. Scales should be fully labelled with units 7. Points should be plotted as crosses 8. Line should be ruiled from point to point, or best fit...this one u all hav to refer back to what kind of experiment/questions.
GOOD PRACTICE IN DRAWING SPECIMENS
1. Lines should be clear and single 2. Proportions should be correct 3. A good level of detail should be shown 4. Low power plans do not show individual cells 5. High power drawings show detail of two or three cells 6. label lines should be drawn with ruler and touch the part being labelled - no arrowheads 7. in general, a scale or magnification should be given
so, practice all this tips...at least u hav a better view in answering and SCORINg paper3..
Today is few tips on answering paper AS or A2 exam
we focus on Command words that always appear in the beginning of da questions.
Command Words
- most question on exam papers do not hav question marks - Question tell candidates what they must do using command words - The command words used and their meaning r listed in syllabus - It is essential that candidates understand these command words
DESCRIBE - the key step in process - the keypoints in some stimulus material
EXPLAIN - the reasons why something happens - the theory shoes why something happens
STATE - means that a short answer is required - it may be only one word - it is a waste of time for candidates to write out a full sentence for such an answer
COMPARE - mean statements about both things or concepts are needed eg Let see if candidates was asked to compare A and B Ok 1. A is green... normally no mark 2. A is greener than B.... awarded a mark 3. A is green but B is yellow... awarded a mark
SUGGEST - this invites candidates to think about what they hav read abd written as answers in da question - Look back to da question before u all writting any 'suggestions' - not necessarily one correct answer - may be several ALTERNATIVE answers...so think more n use ur general knowledges!
OBJECTIVES BIOLOGY WORKSHOP 1) to improve performance of the students by presenting 'common mistakes' @) to expose students to the effective techniques of answering the question 3) to familarise students with the format and mark scheme of particular paper 4) to give students advices or tips before the examination 5) to bring the 'atmosphere of unity' among lecturers and students
APPRECIATION thank you for all the co-operation and attention given. thank you to madam azian, Head of unit biology, Presenter for paper 3 thank you to madam salina, Presenter paper 2 thank you to mr.Addie faris, Presenter paper 4 thank you to mr. Hafiz Abas, Presenter paper 5
and ESPECIALLY to our audience, A-LEVEL STUDENT
YOU ARE FREE TO LEAVE ANY COMMENT TO IMPROVE THIS WORKSHOP IN THE FUTURE!!! THANK YOU VERY MUCH!!!
