MODE OF ASSESSMENT


There are two types of assessment, depending on what you do with them:  Formative Assessment and Summative Assessment.  Formative Assessment is observation to guide further instruction; and the observation is normally not measured, or its measurement is not recorded to grade the students.  Summative Assessment is used to determine a mark or a grade.  There are various ways provided to accomplish formative and summative assessments (Please see the “Teacher’s Guide to Understanding Mathematics, Textbook for class X”).  The mode of assessment given here is for summative assessment of students in class X.  However, observations and analysis made on students’ performance in these summative assessments could very well be used for further instructions.  

In class X, students’ mathematical assessment will be done by two agencies:  The School (or the subject teacher) and the Bhutan Board of Examinations Division (BBED).  The overall weight the school has for the final assessment of the students is 20%, and the rest 80% is determined by the BBED.  The school based assessment is called Internal Assessment, and the BBED carried out assessment is referred to as External Assessment.

Internal Assessment – 20%

The subject teacher will carry out the summative of the students, from the start of the academic session up to the Trail examinations, which lead to the final examinations in December, which is conducted by the BBED.  The mode of the internal assessment will be as per the following break-downs:


 Year beginning to mid-year


Unit Tests:  At the end of each unit, a unit test should be conducted.  It should normally be carried out during one of the class periods.  The unit tests can be directly used or adapted from the ones provided in the Teacher’s Guide, including the marking schemes.  The teacher should keep proper record of the students’ achievement in the series of unit tests.  A minimum of two unit tests should be conducted before the mid-term exams, and the average of the total should be worked out to be worth 5%, and entered onto student’s progress report card.  Please get more information on unit test from the Teacher’s Guide.

Home Works:  Reasonable amounts of home works should be assigned quite regularly. More importantly, they should be checked, and prompt feedback provided to the students on their works. The teacher will check at least two times each student’s home works during the first half term of the year; they can devise their own marking scheme.  The average mark from the total should be worked out to be worth 5% for entering onto the students’ progress report card.  

Performance Tasks and Assessment Interviews:  Performance Tasks require students to perform some mathematical tasks usually requiring problem solving and communication:  they are often hands on activities.  It is not appropriate to give marks or numerical grades to assess students on performance task.  So, a rubric is used to guide the assessment.  Assessment Interviews mean interacting and interviewing students on the concepts learned; asking questions; asking for reasoning; and explanations; and evening demonstrations of their understanding.  Both these two methods of assessments are excellent alternatives to the traditional paper and pencil test assessments.  They can cater to assessing other important aspects of mathematics like problem solving, communication, and reasoning in a better and in-depth manner.  Teachers should carry out at least one performance task and one assessment interview during the first half term of the year.  The average from using these two methods of assessment should then be worked out to be worth 5% for entering in the student’s progress report card.  
Please get more information on Performance Task and Assessment Interviews from the Teacher’s guide and the samples provided with some of the units.

Mid-term examination:  The mid-term examination may be modeled on the Trial Examinations model provided below.  The mark obtained in it should be brought down to 25% for entering into the progress report card.

Mid-year to Year-end:


Unit tests:  To be done similarly as during the first half term of the year, but with the units covered after the mid term examination.

Home works:  To be done similarly as during the first half term of the year.

Performance Tasks and Assessment Interviews:  To be done similarly as during the first half term of the year, but with the units covered after the midterm examination.

Trial Examination (November):  The Trial examinations paper will be set for 100 marks, with the writing time of 3 hours.  The paper will consist of three sections:  Sections A, B and C.   
Section A will be composed of 10 multiple choice questions, and will carry a total of 20 marks.  
Section B will be composed of about 10 to 12 questions requiring short answers, and will carry a total of 32 marks.  




Section C will be composed of 8 pairs of questions, each pair set from one of the 8 units.  Candidates are required to attempt only one question from each of the pairs provided.  The questions making up the pairs should be of equivalent level of difficulty.   Each single question will be worth 6 marks, which then gives a total of 48 marks to this section.  The questions should be composed of inter-related sub questions, designed to test in-depth knowledge and understanding on a particular concept.

Care should be taken to reflect the marks accorded for each unit as per the weighting given below:

Care should also be taken in the preparation of questions having a balance of them requiring conceptual understanding, problem solving, communication, reasoning, and applications of procedural knowledge and skills.  Some questions should cross strands or units.  Along with these, test blue print based on Blooms Taxonomy would also need to be used in the preparation of the paper.

Candidates are permitted to use scientific calculators in the examinations.

The marks obtained out of 100 in this examination should be worked out to be worth 45% for entering in to the students’ progress report card.

The assessments done up to the trial examinations, as would then be reflected or recorded onto the students progress report cards will be out of 100 %.  This over all student achievement will then need to be brought down to be out of 20, and sent to the Bhutan Board of Examinations when asked by BBED in its specified format.

External Assessment – 80%

As already explained, the external assessment consists of the final examination conducted by the Bhutan Board of Examinations Division in December.  This examination carries a weight of 80% of the overall student assessment in class X.  It is therefore clear that this examination is high stake for the students.  But, if done correctly and consistently during the course of the year with the series of internal assessments, the external examination will not be any strange, for it will be based purely on the syllabus.  In fact, the paper will be the exact model of the Trial Examinations outlined above.  For this reason it is not elaborated here.
