Abhijit Banerjee and Esther Duflo won the 2019 Nobel Prize in Economics for their “experimental approach in alleviating global poverty”. Their experimental approach encompassed a variety of novel methods to understand and analyse interventions and Randomised Control Trials (RCTs). Their research has been used by policy makers to make informed policy decisions to best help the marginalised.

What are RCTs?

To understand the effect of a policy, intervention, or medicine, decision makers try to measure the efficacy of the treatment. Do deworming pills given to children improve test scores? Does providing chlorinated water improve the health and economic outcomes of villages? These are some causal (read causal, i.e. caused by, not casual) questions researchers are interested in. The best way to analyse causal effects is to randomise the selection of people in the treatment and the control group (for example: children who are given deworming pills versus children who are not given the pills). This random selection of the two groups removes many statistical biases that might affect the results.

RCTs in India:

Many of the RCTs performed by Banerjee and Duflo were in India. They involved short- and long-term impact assessments of various interventions, policies, models, and treatments. We look at a few RCTs implemented in India:

Teacher absenteeism rates:

Troubled by the low attendance rates (or high absence rates) of public-school teachers in India, Duflo assessed the impact of financial incentives on the absence rates of teachers in Rajasthan. The study monitored teacher attendance by cameras, which was tied to a financial incentive if the attendance was high. From a baseline absence rate of 44%, teacher absenteeism in the treatment group fell by 21%, relative to the control group. High teacher attendance caused child test scores to improve too.

COVID-19 and health-seeking behaviour:

In the context of COVID-19, Banerjee tested the effect of sending messages via SMS that promoted health preserving behaviour. The results were very positive. By sending a short, 2.5-minute clip to 25 million randomly selected individuals in West Bengal, the intervention i) found a two-fold increase in symptom reporting to village health workers, ii) increased hand washing rates by 7%, and iii) increased mask-wearing by 2%. While mask-wearing rates increased only marginally, the spillover effects (wearing a mask stops the virus from infecting more people) were moderately high and positive.

Asset Transfers and the Notion of Poverty:

An RCT by Banerjee in West Bengal involving a productive asset transfer accompanied with training found large and persistent effects on monthly consumption and other variables. The treatment group reported 25% higher consumption levels relative to the control group, who did not receive the asset transfer and training. Implications of such RCTs are huge. The notion that the poor are lazy and unwilling to perform strenuous labour is falsified by this RCT. Often, what the poor lack are opportunities that are hard to come by, given their financial status. A small nudge, like the asset transfer, can cause large and positive effects on their well-being.  

Salt fortification to reduce anaemia:

RCTs also help rule out less cost-effective interventions. Duflo and Banerjee evaluated an RCT which distributed fortified salt in 400 villages of Bihar, to reduce the prevalence of anaemia. However, this intervention found no statistically significant impact on health outcomes like anaemia, hemoglobin, etc.  Thus, while RCTs help introduce novel methods of impacting the lives of the poor, they also help in ruling out in-effective measures. A policy maker might try other alternatives to reduce the prevalence of anaemia.

Are RCTs the gold standard?

Maybe. Extrapolating results from a regional RCT to national policies could present problems. Contextuality matters. A study that indicates positive gains for one region might present different, and rather adverse effects for another region. Nation wide effects might not be as prominent as regional results of a single RCT. The good part is that Banerjee and Duflo have a solution. Just perform more RCTs!

India’s New Education Policy (NEP) 2020: What it proposes for Schools

On 30th July 2020, the Indian government’s Ministry of Human Resource Development (MHRD) was renamed the Ministry of Education as it announced the new National Education Policy (NEP) 2020.

The National Education Policy is an in-depth framework outlining the future and development of education in India. It’s recommendations guide what the priorities and goals of educational institutions should be in the coming years. The first NEP was passed in 1968; while it gets revised occasionally, a new NEP has only been passed two times since then, in 1986 and now in 2020.

Prime Minister Narendra Modi’s and the government was hailed by RSS-affiliated educational organisations for the NEP as a step to connect the education with the roots of India. They reportedly had quite an influence during the drafting of NEP, even going as far as to say that “60-70 percent” of their demands have been met.

On the other hand, NEP received criticism from the opposition parties like Congress, the Communist Party of India (Marxist), and political figures in West Bengal and Tamil Nadu. The criticism was primarily for bypassing Parliamentary discussion, and its ill-fittedness in the context of the COVID-19 pandemic and the ever-growing digital divide left in its wake in the education sector.

The NEP’s ambitious claims and propositions are divided into two broad categories: school, and higher education.

NEP at School Level

At school level, perhaps the biggest change is the move away from the 10+2 structure to a 5+3+3+4 one, signifying four stages of school education across ages 3-8 years (Foundational), 8-11 years (Preparatory), 11-14 years (Middle) and 14-18 years (Secondary). This new structure claims to be based greatly on the cognitive development of children and prioritising areas of focus through these ages.

The new structure also talks about the Early Childhood Care and Education (ECCE), which aims to include pre-schools and aanganwadis (government sponsored rural child care centres in India) in an effort to impart play and activity focused learning, and train aanganwadi workers to achieve the same.

However, the treatment of the aanganwadi program is already under question from the governance and child right watchdogs and activists . This program is poorly funded and workers are poorly paid which makes the promise of training the workers for implementing the NEP goals seem quite wishful. This means rural students are likely to continue to be many steps behind urban students from the ECCE i.e ‘Foundational’ stage itself.

National Assessment Centre

NEP proposes the establishment of a National Assessment Centre, PARAKH, to set norms and guidelines for evaluations across all school boards. Report-cards are also to be redesigned and include self, teacher and peer assessment. However, the details of what will entail in these, especially peer assessment, are vague and do not take into cognizance the rampant prejudice and bullying experienced by students at the hands of peers as well as teachers on bases of weight, religion, gender, caste, class, sexuality and more. Such discriminatory practices will hurt the students from marginalised communities in both disguised and explicit ways.

The 3 Language Formula

A more controversial change comes with the 3-Language Policy, which essentially asks that “wherever possible,” the regional language or mother tongue of a student be adopted as the medium of instruction “until at least Class 5, but preferably till Class 8 and beyond.”

All schools will teach three languages, of which at least two must be native to India. The draft NEP, in fact, mandated that one of these languages be Hindi; after protests against this ‘Hindi imposition’ such as by the southern state of Tamil Nadu, this provision was removed and it has supposedly been left to the state, school and student to decide which languages would be taught.

The so-called flexibility of the policy comes at the cost of uniformity. Since the colonial era, English education has served as a means of upward social mobility for castes and tribes that had historically been denied education under Brahmanical hegemony, this progress is threatened by making English ‘optional’ in any form.

There are also unaddressed and obvious scenarios of parents who migrate or get transferred to different states, parents who speak another language at home than the regional language, and children who grow up in multilingual homes, all of which are commonplace across India. How likely is it that every student in a classroom speaks the same mother tongue or is from the same region?

Promotion of Sanskrit

The NEP desires that the rich ancient languages of India be brought back to the forefront and be given more focus as languages that can be taken up by students. In this regard it shines a spotlight on Sanskrit, a classical language rooted in Hinduism which was for centuries only accessible to Brahmins and some other upper castes. The pedestal upon which Sanskrit has been placed is being seen as discriminatory towards the large population of India who either do not have historic ties to Sanskrit or were denied access to it.

While the NEP does mention other languages that have had a strong foothold in India for a long time, such as Persian and Prakrit, it notably omits mention of Urdu and seems especially driven to ‘promote’ Sanskrit.

Vocational Education

The NEP points out that a very small portion of the Indian workforce in the age group 19-24 is exposed to vocational education, and therefore recommends that it be integrated in schools and higher education in a phased manner over the next 10 years.

A focus on vocational education starting from ages as young as 14 is also questionable, since non-formal education, often valued less than degrees, might hinder the education of poor children. This may contribute to deepening the class divide in India since receiving Undergraduate or Postgraduate degrees often guarantees poverty alleviation for such students.

Additionally, vocational education will likely form a vicious cycle with the entrenched caste system in India, reinforcing each other and the inequalities therin.

It has been repeatedly asserted by experts, citizens and politicians alike that the NEP caters more to the corporate interests over the needs of underprivileged students, and has brought much uncertainty around the question of language.

It becomes vague at key points, falling back on the argument that it is only a ‘guiding document,’ which only makes its stances seem weaker, in both theory and practice.

Whether the NEP as a whole manages to turn the tide of education in favour of those who need it the most, and is able to mobilise it as a tool for progress, presently seems more fantastical than plausible.
