Pedagogy For the above experiments the following pedagogy can be considered. Problem based learning, Active learning, MOOC, Chalk &Talk

PART B – Practical Based Learning

A problem statement for each batch is to be generated in consultation with the co-examiner and student should develop an algorithm, program and execute the program for the given problem with appropriate outputs.

Course Outcomes:

CO 1. Demonstrate proficiency in handling of loops and creation of functions.

CO 2. Identify the methods to create and manipulate lists, tuples and dictionaries.

CO 3. Discover the commonly used operations involving regular expressions and file system.

CO 4. Interpret the concepts of Object-Oriented Programming as used in Python.

CO 5. Determine the need for scraping websites and working with PDF, JSON and other file formats.

Assessment Details (both CIE and SEE)

• The weightage of Continuous Internal Evaluation (CIE) is 50% and for Semester End Exam (SEE) is 50%.
• The minimum passing mark for the CIE is 40% of the maximum marks (20 marks).
• A student shall be deemed to have satisfied the academic requirements and earned the credits allotted to each course. The student has to secure not less than 35% (18 Marks out of 50) in the semester-end examination (SEE). The student has to secure 40% of sum of the maximum marks of CIE and SEE to qualify in the course.

Continuous Internal Evaluation (CIE):

CIE marks for the practical course is 50 Marks.

The split-up of CIE marks for record/ journal and test are in the ratio 60:40.

• Each experiment to be evaluated for conduction with observation sheet and record write-up. Rubrics for the evaluation of the journal/write-up for hardware/software experiments designed by the faculty who is handling the laboratory session and is made known to students at the beginning of the practical session.
• Record should contain all the specified experiments in the syllabus and each experiment write-up will be evaluated for 10 marks.
• Total marks scored by the students are scaled downed to 30 marks (60% of maximum marks).
• Weightage to be given for neatness and submission of record/write-up on time.
• Department shall conduct 02 tests for 100 marks, the first test shall be conducted after the 8th week of the semester and the second test shall be conducted after the 14th week of the semester.
• In each test, test write-up, conduction of experiment, acceptable result, and procedural knowledge will carry a weightage of 60% and the rest 40% for viva-voce.
• The suitable rubrics can be designed to evaluate each student’s performance and learning ability. Rubrics suggested in Annexure-II of Regulation book
• The average of 02 tests is scaled down to 20 marks (40% of the maximum marks).

The Sum of scaled-down marks scored in the report write-up/journal and average marks of two tests is the total CIE marks scored by the student.

Semester End Evaluation (SEE):

• SEE marks for the practical course is 50 Marks.
• SEE shall be conducted jointly by the two examiners of the same institute, examiners are appointed by the University
• All laboratory experiments are to be included for practical examination.
• (Rubrics) Breakup of marks and the instructions printed on the cover page of the answer script to be strictly adhered to by the examiners. OR based on the course requirement evaluation rubrics shall be decided jointly by examiners.
• Students can pick one question (experiment) from the questions lot prepared by the internal /external examiners jointly.
• Evaluation of test write-up/ conduction procedure and result/viva will be conducted jointly by examiners.
• General rubrics suggested for SEE are mentioned here, writeup-20%, Conduction procedure and result in -60%, Viva-voce 20% of maximum marks. SEE for practical shall be evaluated for 100 marks and scored marks shall be scaled down to 50 marks (however, based on course type, rubrics shall be decided by the examiners)
• Students can pick one experiment from the questions lot of PART A with equal choice to all the students in a batch. For PART B examiners should frame a question for each batch, student should develop an algorithm, program, execute and demonstrate the results with appropriate output for the given problem.
• Weightage of marks for PART A is 80% and for PART B is 20%. General rubrics suggested to be followed for part A and part B.
• Change of experiment is allowed only once and Marks allotted to the procedure part to be made zero (Not allowed for Part B).
• The duration of SEE is 03 hours

Rubrics suggested in Annexure-II of Regulation book
