Single National Curriculum (SNC): Its Pros & Cons

Single National Curriculum 2020  Background Pakistan is a multi-lingual, multi-cultural, and multi-ethnic country where around 74 different languages are spoken. Out of these 74 different languages, 66 languages are indigenous while the remaining 8 are non-indigenous. Urdu is the national language while English is the official language of Pakistan.  Similarly, Pakistan is the thick and second-largest Muslim-populated country in the world. Approximately 96.5% (≈210 million) people are Muslims, out of which around 85-90% are Sunni and the remaining are the Shia sect Muslims.  These two major sects are further subdivided into different groups on the basis of their particular schools of the so-called Islam ic law. On the other hand Pakistani nation is divided on the basis of political parties, ethnicity, sectarianism, culture, customs, traditions, rituals, socio-economics, and educational differences.  The current government has therefore developed and devised Single N...

Definition and Scope of Statistics (Quantitative Reasoning Course)

Quantitative Reasoning Course for BS Honours Level Students  Definition and Scope of Statistics Statistics is the branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organisation of data. It provides tools and methods to make sense of numerical information, identify patterns, draw inferences, and make informed decisions under uncertainty. The scope of statistics is broad and interdisciplinary: Descriptive Statistics : Summarises and describes the features of a dataset, such as calculating means, medians, or creating charts to visualise data. Inferential Statistics : Uses sample data to make generalisations or predictions about a larger population, often involving hypothesis testing, confidence intervals, and regression analysis. Applied Fields : Extends to economics (e.g., forecasting trends), biology (e.g., clinical trials), social sciences (e.g., surveys), engineering (e.g., quality control), and data science (e.g., machine learning m...

Quantitative Reasoning Statistical Basics

Measures of Central Tendency Measures of central tendency are the specific statistical values which describe the typical values or central position of a dataset. The three most common single statistical values include Mean, Median and Mode.  Arithmetic Mean : Average of all values (sum divided by count). Geometric Mean : nth root of the product of values (used for growth rates). Harmonic Mean : The Reciprocal of the average of reciprocals (used for rates like speed). Median : Middle value when data is ordered. Quartiles : Values dividing data into four equal parts (Q1=25th, Q2=50th=median, Q3=75th percentile). Mode : Most frequent value. Measures of Dispersion Range : Difference between maximum and minimum values. Quartile Deviation : Half the interquartile range (Q3 - Q1)/2. Mean Deviation : Average absolute deviation from the mean. Variance : Average squared deviation from the mean. Standard Deviation : Square root of variance (spread in original units). Coefficient of Varia...

Dilema of Democracy & Political Leadership Crisis in Pakistan

Dilemma of Democracy & Political Leadership Crisis in Pakistan Overview Since mid 20th century,  Democracy is being considered the most accomplished process and a form of government where only people’s representatives have the right and authority to run the affairs of the state including forming certain constitutional rules and regulations.  Through democracy, people choose their representatives following a well-defined system of voting. The elected representatives then govern the affairs of the state on behalf of their people for a certain period of time (usually 4 to 5 years).  These representatives actually ensure the authority and rule of law for their people in the larger interests of any nation, state, or country. On the other hand, they are also held accountable and responsible for their actions and exercising of the powers within certain limitations as defined in the constitution or legislated through parliament.  Although Pakistan is a pure democratic...

Sampling Techniques

Sampling Techniques: Quantitative Reasoning Course for BS Honours Level Students  Sampling technique involves selecting a subset of a population to study, enabling researchers to draw quantitative, qualitative and mixed conclusions about the larger group without studying everyone.  In Linguistics and Education or in any other field of study, sampling is crucial because populations (e.g., language speakers, students, teachers, customers,  users, and viewers etc.) are often large and diverse, making it impractical to study every individual.  The choice of sampling technique impacts the study’s validity, generalisability, and feasibility. Types of Sampling Techniques Basically, there are two main types of sampling techniques that are further subdivided. Both of these types including subtypes are explained below with examples. 1. Probability Sampling (Random-based, ensures every unit has a known chance of selection) Simple Random Sampling : Every individual in the popul...

AFGHANISTAN CRISES: WHERE DOES PAKISTAN STAND?

Afghanistan Crises and Pakistan  Background According to history, Afghanistan has remained a war zone and a plan to invade central and south Asia for a long time. All of the invaders' troops entered South Asia through Afghanistan, from the Aryans to the Mughals. Afghanistan was the target of two major invasions in recent history. The former Soviet Union (USSR) launched its first invasion in December 1979, which lasted until 1989 and culminated in the dissolution of the Soviet Union into a number of distinct states. However, a significant portion of the formal USSR's territory, now known as the Russian Federation, is still there. As a result of the so-called September 11, 2001 attacks on the World Trade Center in New York, the United States of America (USA) and its NATO (North Atlantic Treaty Organization) allies, including Great Britain, launched the second invasion in 2001. Al-Qaeda's leader, Usama Bin Ladin, was allegedly blamed for the 9/11 attacks and claims that Al-Qa...

SWOT Analysis within the Context of Education

 SWOT Analysis in Education for Curriculum Development, Classroom Management, and Planning Introduction   It was the Stanford Research Institute (SRI) which coined the term SWOT Analysis during the 1960s. Initially, the term was used for business management consultancy but later on, researchers and professionals started using it in different fields mainly for planning purposes. SWOT  analysis is a strategic planning tool or a framework which is used to identify and evaluate the Strengths, Weaknesses, Opportunities, and Threats related to an organization or a specific project including setting its standing operating procedures (SOPs).  It is widely used in business studies, politics, strategic military planning, think tanks, policy-making, international relations, socio-economic as well as socio-political dimensions, and education etc. Similarly, in the context of education, SWOT analysis provides a very comprehensive framework for assessing various aspects of educat...
