CBSE tightens affiliation rule

The Central Board of Secondary Education (CBSE) has discontinued the provision of granting permanent affiliation to schools run by private managements and public sector undertakings (PSUs).
Now the private and PSU-run schools will have to apply for renewal of application every three years or five years, in a move decried as the national board's attempts at "commercialisation". The CBSE charges a fee of Rs 25000 for processing applications for renewal of provisional affiliations.
Last week CBSE amended its bylaws to scrap the system under which schools that had been provisionally affiliated to the CBSE for more than 10 yrs and were fulfilling all the requirements like land, building and teachers were given permanent affiliation.
"The board has decided to discontinue the provisions of permanent affiliation bylaws," said a circular issued by CBSE secretary on January 3.
The circular was issued after CBSE governing body decided to tighten its affiliation rule at its meeting on December 18 last year. Earlier, the affiliation committee of the CBSE had suggested such a measure.
The board has around 19500 affiliated schools, including 15000 private institutions.
The CBSE has been giving provisional affiliation to new private schools, regular one time affiliation to government schools and permanent affiliation to private and PSU-run schools having completed provisional affiliation for 10 years.
Now in general, this can be interpreted that the system of renewal of applications has been made to ensure continuous scrutiny and maintenance of standards in schools. However, the regular one time affiliation for government schools will continue as usual.

CBSE Guess Questions with their Answers (Short)

Question.1: When and who appointed the Company as Diwan of Bengal?

Answer: On 12th August, 1765, the Mughal emperor appointed the East India Company as the Diwan of Bengal.


CBSE Guess Questions with their Answers (Long)

Question.2: Write short notes on:
i. Permanent Settlement.
ii. Mahalwari System.
iii. The Munro System (Ryotwari System).

Answer:
        (i)        Permanent Settlement: The Bengal economy fell sharply was facing a deep crisis after the company was given the rights of Diwan. The company officials realized that it was due to their lack of planning which led to the downfall in Indian economy and their revenue collection.  The zamindars were not investing for the improvement of land. In order to encourage investment in land and improve agriculture the company introduced the Permanent Settlement in 1793.It was devised by Lord Cornwallis. According to this system The Rajas and Taluqdars were recognized as Zamindars. They were agreed to collect rent from the peasants and pay revenue to the Company. The amount to be paid (revenue) was fixed permanently that it was not to be increased ever in future. The condition was that the Zamindars had to pay this revenue rigidly on due date even if the crop had failed for some reason as otherwise the land was auctioned. It was felt that this would ensure a regular flow of revenue into the Company’s coffers and at the same time encourage the Zamindars to invest for improving the land because the zamindar would benefit if he could increase production from the land by his own efforts. On the contrary the Company officials ultimately discovered that the zamindars were not interested in investment for improvement of the land. It was also discovered that the revenue which had been fixed was so high that the zamindars found it difficult to pay. The peasants were in distress as they found the system extremely oppressive. So ultimately the ‘Permanent Settlement’ system was not successful as expected. 

      (ii)        Mahalwari System: As the Permanent Settlement system became unsuccessful so, the Company introduced another system popularly known as Mahalwari System. This system was devised by Holt Mackenzie which came into effect in 1822 in the North West provinces of Bengal Presidency. The revenue was not fixed and the Government could increase the same whenever it was in need of money to meet its expenses of administration. The estimated revenue of each plot within a village was added up to calculate the revenue that each mahal (village) had to pay. The charge of collecting the revenue and paying it to the Company was given to the village headman. Thus the ‘village’ and the ‘village headman’ would benefit since there was no middleman between the British and the village headman. The village headmen had a scope to negotiate with the Company if they were unable to pay the revenue fro some reason and also continued to cultivate the land.

     (iii)        The Munro System (Ryotwari System): In the British territories of the south a similar system existed as the Permanent Settlement. The new system was known as the ‘ryotwari system’. Captain Alexander Read tried this on small scale in some of the areas annexed after the wars with Tipu Sultan. Since this system was developed by Thomas Munro so, it is also known as Munro System. It was gradually extended all over South India. Read and Munro found that there were no traditional zamindars. This settlement had to be made directly with the cultivators (ryots) who had tilled the land for generations. The fields of cultivators had to be carefully and separately surveyed before the assessment of revenue. Munro had the idea that the British should not act as paternal father figures who would protect the ryots under their charge. But within a few years it was felt that all not well as nothing happened as it was expected. The revenue officials fixed too high a revenue demand. Ryots were not able to pay the revenue. As a result they fled to the countryside and villages became deserted. Although it was expected that the new system would transform the peasants into rich farmers, but it failed to happen.

Question 1. What is a true solution?  Give an example.
Answer: A homogenous mixture of two substances, in which particles of both possess molecular dimensions (i.e., 10-10 to 10-9 m). For example, a solution of common salt in water.
Question 2. What is a colloidal solution?  Give an example.
Answer: A colloidal solution is a two-phase heterogeneous system in which a substance is distributed in colloidal state (particles having diameter between 1 to 100 nm) in a medium. The particles of the dispersed substance (of colloidal size) are called dispersed phase; while the medium in which they are dispersed, is called dispersion medium.  For example, milk, butter, smoke, etc. 
Question 3. What is the size of colloidal particles?
Answer: Diameter of colloidal particles is between 1 - 100 nm.
Question 4. What are lyophilisation and lyophobic sols?
Answer: A lyophilic sol is a colloidal solution in which there is great is affinity between colloidal particles and the dispersion medium. For example, starch sol, gum sol etc.
A lyophobic sol is a colloidal solution in which there is little affinity between colloidal particles and the dispersion medium. For example, sulphur sol, gold sol, etc. For example, starch sol is a lyophilic sol whereas sulphur sol is a lyophobic sol. 
Question 5. Give two examples of positively charged sols.
Answer: Ferric hydroxide sol and aluminium hydroxide sol.
Question 6. Give example of negatively charged sol.
Answer: Arsenious sulphide sol.
Question 7. Why cannot we prepare a colloidal solution of a gas in a gas?
Answer: The mixture of any two gases is always a homogeneous mixture whereas a colloidal solution is always heterogeneous.
Question 8. How can a colloidal solution and a true solution of the same colour be distinguished from each other?
Answer: A colloidal solution and a true solution of the same colour can be distinguished by passing a powerful beam of light through true and colloidal solutions, each kept in glass vessel. Only colloidal solution exhibits Tyndall Effect whereas true solution does not.    
Question 9. Define the term “Dialysis”. Tell about the use of dialysis.
Answer: The process of separating electrolytes from a colloid by means of diffusion of the former through an animal or vegetable membrane is called Dialysis.
Dialysis is used for purifying colloidal solution. In the presence of excess of electrolytes, the colloidal solutions get coagulated.
Question 10. Can we make Dialysis fast? If yes, how?
Answer: By circulating hot water instead of cold water, in container or by applying electric field across the dialyser.
Question 11. What is “Coagulation”?
Answer: Coagulation is the process of changing the colloidal state into an insoluble precipitate, by including aggregation of colloidal particles.
Question 12. Name a few methods of coagulating lyophilic colloids.
Answer: (i) Addition of electrolyte. (ii) Addition of a liquid in which the dispersion medium is soluble.
Question 13. What is meant by “Peptization”?
Answer: The method of breaking down a precipitate into colloidal form by shaking with the dispersion medium in presence of an electrolyte is called “Peptization”.
