Note: The above are only the specimens of activities. In order to arouse creativity, the students must be encouraged to take up new activities (other than mentioned above) in consultation with the teacher concerned.

6. Learning Facilitation 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 teaching-learning 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. Self-study by students is highly encouraged and learning should not be confined to the scope of curriculum. Teacher should keep in mind intra and inter-disciplinary 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 is anticipated.

During the delivery process of science teaching in grade 11 and 12, basically following three approaches will be adopted;

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 self-learning 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;

· Mini research

· Survey

· Model construction

· Paper based work

· study of ethno-science

General process of research work embraces the following steps;

· Understanding the objective of the research

· Planning and designing

· Collecting information

· analysis and interpretation

· Reporting /communicating (presentation, via visual aids, written report, graphical etc.) General process of innovative work embraces the following steps;

· identification of innovative task (either assigned by teacher or proposed by student)

· planning

· performing the task

· presentation of the work

· Record keeping of the work

Students are free to choose any topic listed in this curriculum or a topic suggested by teacher provided that it is within the theoretical contents of the Curriculum. However, repetition of topic should be discouraged.

Basic Science Process Skills includes

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 question-answer, 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 Activities (Practical works and projects works) (16 marks), (b) Marks from trimester examinations (6 marks), and (c) Classroom participation (3 marks)

· Practical Activities

Practical work should be based on list of activities mentioned in this curriculum. Project works should be based on the mentioned lists or created by teachers. Mark distribution for practical work and project work will be as follows:

S. N.	Criteria	Elaboration of criteria	Marks
1.	Laboratory experiment	Correctness of apparatus setup/preparation	2
		Observation/Experimentation	2
		Tabulation	1
		Data processing and Analysis	1
		Conclusion (Value of constants or prediction with justification)	1
		Handling of errors/precaution	1
2.	Viva-voce	Understanding of objective of the experiment	1

		Skills of the handling of apparatus in use	1
		Overall impression	1
3.	Practical work records and attendance	Records (number and quality)	2
4	Project work	Reports (background, objective, methodology, finding, conclusion	2
4	Project work	Presentation	1
		Total	16

Note:

(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).
