6. Learning Facilitation Method and Process
Students should be facilitated to learn rather than just accumulation of information. Teacher plays vital role for delivering subject matters although others' role is also important. Student centered teachinglearning process is highly emphasized. Students are supposed to adopt multiple pathway of learning, such as online search, field visit, library work, laboratory work, individual and group work, research work etc. with the support of teacher. Selfstudy by students is highly encouraged and learning should not be confined to the scope of curriculum. Teacher should keep in mind intra and interdisciplinary approach to teaching and learning, as opposed to compartmentalization of knowledge. Supportive role of parents/guardians in creating conducive environment for promoting the spirit of inquiry and creativity in students' learning i anticipated.
During the delivery process of science teaching in grade 11 and 12, basically following three approaches will be adopted;
a. Conceptual/Theoritical:
Knowledge of content (fact,terminology,definitio ns,learning procedures
Understanding of content ( concept,ideas,theories,priciples), 3.5 credit hrs spent for understanding of content.
b. Practical/Appication/Experimental:
Lab. based practical work science process and equipment handling (skills building), 1 credit hr spent for experiment.
c. Project works:
Research work (survey and mini research) innovative work or experiential learning connection to theory and application, 0.5 credit hr spent in field work.
a) Conceptual/Theoretical Approach:
Possible theoretical methods of delivery may include the following;
lecture
interaction
question answer
demonstrations
ICT based instructions
cooperative learning
group discussions (satellite learning group, peer group, small and large group)
debate
seminar presentation
Journal publishing
daily assignment
b) Practical/Application/Experimental approach:
Practical work is the integral part of the learning science. The process of lab based practical work comprises as;
familiarity with objective of practical work
familiarity with materials, chemicals, apparatus
familiarity with lab process (safety, working modality etc.)
conduction of practical work (systematically following the given instruction)
analysis, interpretation and drawing conclusion
c) Project work Approach:
Project work is an integral part of the science learning. Students should be involved in project work to foster selflearning of students in the both theoretical and practical contents. Students will complete project work to have practical idea through learning by doing approach and able to connect the theory into the real world context. It is regarded as method/ process of learning rather than content itself. So use of project work method to facilitate any appropriate contents of this curriculum is highly encouraged.
In this approach student will conduct at least one research work, or an innovative work under the guidance of teacher, using the knowledge and skills learnt. It could include any of the followings;
(a) Mini research
(b) Survey
(c) Model construction
(d) Paper based work
(e) study of ethnoscience
General process of research work embraces the following steps;
Understanding the objective of the research

1. Observing: using senses to gather information about an object or event. It is description of what was actually perceived.
2. Measuring: comparing unknown physical quantity with known quantity (standard unit) of same type.
3. Inferring: formulating assumptions or possible explanations based upon observations.
4. Classifying: grouping or ordering objects or events into categories based upon characteristics or defined criteria.
5. Predicting: guessing the most likely outcome of a future event based upon a pattern of evidence.
6. Communicating: using words, symbols, or graphics to describe an object, action or event.
Integrated Science Process Skills includes,
1. Formulating hypotheses: determination of the proposed solutions or expected outcomes for experiments. These proposed solutions to a problem must be testable.
2. Identifying of variables: Identification of the changeable factors (independent and dependent variables) that can affect an experiment.
3. Defining variables operationally: explaining how to measure a variable in an experiment.
4. Describing relationships between variables: explaining relationships between variables in an experiment such as between the independent and dependent variables.
5. Designing investigations: designing an experiment by identifying materials and describing appropriate steps in a procedure to test a hypothesis.
6. Experimenting: carrying out an experiment by carefully following directions of the procedure so the results can be verified by repeating the procedure several times.
7. Acquiring data: collecting qualitative and quantitative data as observations and measurements.
8. Organizing data in tables and graphs: presenting collected data in tables and graphs.
9. Analyzing investigations and their data: interpreting data, identifying errors, evaluating the hypothesis, formulating conclusions, and recommending further testing where necessary.
10. Understanding cause and effect relationships: understanding what caused what to happen and why.
11. Formulating models: recognizing patterns in data and making comparisons to familiar objects or ideas.
7. Student Assessment
Evaluation is an integral part of learning process. Both formative and summative modes of evaluation are emphasized. Formative evaluation will be conducted so as to provide regular feedback for students, teachers and parents/guardians about how student learning is. Class tests, unit tests, oral questionanswer, home assignment etc. are some ways of formative evaluation.
There will be separate evaluation of theoretical and practical learning. Summative evaluation embraces theoretical examination, practical examination and evaluation of research work or innovative work.
(a) Internal Evaluation
Out of 100 full marks Internal evaluation covers 25 marks. Internal evaluation consists of Practical work (16 marks), (b) Marks from trimester examinations (6 marks), and (c) Classroom participation (3 marks)

(i) Practical examination will be conducted in the presence of internal and external supervisors. Evaluation of laboratory experiment will focus both the product of work and skills competencies of student in using apparatus.
(ii) Project work assessment is the internal assessment of reports and presentation of their project works either individually or group basis. In case of group presentation, every member of the group should submit a short reflection on the presented report in their own language. Records of project works must be attested by external supervisor.
⇴ Marks from trimester examinations
Total of 6 marks; 3 marks from each trimester.
⇴ Classroom participation (3 marks)
Classroom participation includes attendance (1) and participation in learning (2).
(b) External Evaluation
Out of 100 marks theoretical evaluation covers 75 marks. The tool for external evaluation of theoretical learning will be a written examination. Questions for the external examination will be based on the specification grid developed by Curriculum Development Centre. Examination question paper will be developed using various levels of revised Bloom's taxonomy including remembering level, understanding level, application level and higher ability (such as analyzing, evaluating, creating).
