Virtual assessment need not terrify universities


In one of the big stories in The Standard of May 26, 2020, it is reported that public universities in Kenya are facing a challenge in administering end of semester exams following the end of online lectures. Assessment and feedback practices can be challenging even in the best of times, especially if virtual. It is therefore understandable that universities are struggling to manage assessment during the current pandemic.

I have had occasion to reflect on the question of the role of assessment and feedback in a student-centered learning environment. My conclusion, which some may (dis)agree with is that, in both theory and practice, there needs to be alignment between the learning outcomes, teaching and learning activities, as well as the assessment strategy.

John Biggs – the famous Australian educational psychologist – proposed[1] the adoption of a constructivist pedagogical approach where the focus is always on what the learner is actually doing, placing the learning activities at the heart of the process. This is easier said than done in time of "inside and online".

While Kenyan universities would in all likelihood have established clear guidelines for teaching, learning and assessment that faculties and departments are required to implement, the need to have complementary mechanisms for quality inspection and quality control with regard to assessment and feedback as central components of the teaching and learning process cannot be overstated. 

In the referenced story, university officials are said to be exploring ways to come up with secure and cost-effective methods of assessing students online, which will guarantee quality and check exam malpractice.

I have previously argued that assessment and feedback has an important role in students’ learning. It acts as an important interface between learning objectives and outcomes. Judicious use of effective assessment methods and practices has value and potential to significantly improve learning outcomes. Given that there are diverse assessment methods, selective application of such methods is of essence and has a bearing on learning, particularly in the context of virtual teaching and learning.

In my experience I found that adapting assessment methods and practices to students’ learning styles and processes holds great promise to improving learning outcomes. This means that assessments methods and practices must be adapted to the reality under Covid-19. Since this is new for most of us it goes without saying that there is need for research on design and use of diverse assessment methods in all levels of learning domains.

Sharing experiences on various aspects of assessment design and application across the academe can go a long way in making the search for effective assessment solutions less daunting, and certainly less traumatic than the report suggests.

People First


Valuing things over people is an embarrassing indictment to humanity’s conscience

The 2019 coronavirus disease (2019-nCoV, more widely known as COVID-19), is a human disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Emphasising the human dimension of this voracious pandemic that has rapidly morphed into a global health emergency of unprecedented proportion is nontrivial and as urgent as it gets.

The inordinate attention to things rather than to people even before the coronavirus crisis wanes is an embarrassing affront to humanity[1]. If there is one lesson to be drawn from the COVID-19 pandemic it is that people must be the main foci of attention in both academic and public discourse.  A system that values things more than people was bound to lead to the sorts of tragic outcomes and impacts currently witnessed across the world as nations scramble to fight the pandemic.

As if in lock and step, governments have been quick off the block to vote for hefty stimulus packages to bail out businesses. But, the pace with which testing, contact tracking and isolation has been doled out has, with a few exceptions, been lacklustre as best[2],[3].This is in spite of an overwhelming consensus among epidemiologists and the scientific community that, short of a vaccine, testing, tracing and isolation is the most effective bulwark humanity has to fight the pandemic.

In a characteristic mainstream valuation of (material) things over people, the lead story in The Economist of May 14, 2020, titled “Has covid-19 killed globalisation?” argues that the open system of trade (not people) that has hitherto been dominant is “suffering a body-blow due to lockdowns that have sealed borders and disrupted commerce”. To support this viewpoint, the following statistics is given:

“The number of passengers at Heathrow has dropped by 97% year-on-year; Mexican car exports fell by 90% in April; 21% of transpacific container-sailings in May have been cancelled. As economies reopen, activity will recover, but don’t expect a quick return to a carefree world of unfettered movement and free trade”.                
If there was any doubt, the above quotation, among many (see, for example, the article titled “The pandemic’s coming geopolitical second wave” in May issue of The Atlantic for a European perspective), puts to rest any pretence that proponents of globalisation care for much more than about protectionism, economic growth, finance, markets, costs, global trade, and foreign direct investment. Whatever the validity of contrary views, nothing can diminish the gravity of this matter. It is people’s lives at stake here!


[1] An editorial published on in the prestigious medical journal The Lancet (Vo 395, Issue 10236, May 16, 2020) suggests that the US prioritised politics over public health in its COVID-19 response. Incidentally, this is not the first time that an administration is playing politics with public health (see Editorial of The Lancet Vol 370, July 21, 2007).    
[2] Writing in the Financial Time of April, 3 2020, acclaimed novelist Arundhati Roy narrates how the Indian government bungled at each and every step of its response to the coronavirus pandemic, pointing out, for example, that…”the calamitous lack of planning or preparedness (that) turned the world’s biggest, most punitive lockdown into the exact opposite of what it was meant to achieve” (https://www.ft.com/content/10d8f5e8-74eb-11ea-95fe-fcd274e920ca).
[3] Commenting on Kenyan politics, acclaimed journalist Tom Mshindi characterises it as “a battle that is of little benefit to the majority of Kenyans confronting life and death situations in the devastation Covid-19 is leaving in its wake, the floods and the inevitable starvation that will follow (Daily Nation of May 16, 2020).

Bemoaning potential loss of raw material export earnings shameful


Unequal Exchange

Africa has been involved in unequal exchange through the export of raw materials and import of finished products. This position means that Africa perpetually suffers unfavourable balance of trade, underdevelopment, and a general state of relative deprivation.

Any keen student of the dialectics of development and underdevelopment would therefore find it appalling to read commentaries bemoaning future loss of export earnings due to projected fall in (raw material) prices as a result of COVID-19 pandemic-inspired recession.

Time to change the narrative

Import substitution industrialisation (ISI) was once in vogue, until it got a bad name. How about giving ISI the good name it once had? Now is time to implement (not develop) strategies, such as Agenda 2063 and the African Continental Free Trade Area (AfCFTA) Agreement.

For avoidance of doubt, the AfCFTA Agreement entered into force on 30 May 2019 for the 24 countries that had deposited their instruments of ratification with the African Union Commission (see the visual below). Subsequently, at an Extraordinary Summit of the African Union held on 7 July 2019, the operational phase of the AfCFTA Agreement was officially launched.

Delivering sanitation and hygiene in Africa: a public health emergency


On 21 December 2016, the UN General Assembly adopted resolution 71/222 proclaiming the decade 2018 – 2028 as the International Decade for Action, “Water for Sustainable Development”.[1]  With the world currently laser focused on the COVID-19 pandemic, it is appropriate to say something about public health.

Globalwaters.org has a simple definition of “sanitation” and “hygiene”. Sanitation includes facilities, behaviours, and services that prevent diseases caused by contact with human waste. “Hygiene” refers to behaviours that can improve cleanliness and lead to good health. The former encompasses facilities and behaviour whereas the latter is purely behavioural. In other words, sanitation and hygiene is all about public health.

The Centre for Disease Control and Prevention offer the following explanation. Sanitation and hygiene are critical to health, survival and development.  Premised on this, it follows that investing in basic sanitation as well as providing services such as garbage collection, waste (domestic and industrial) management, and wastewater treatment and disposal would significantly improve global health conditions.

Both World Health Organisation and UNICEF data show that more than 32% of the world’s population are at risk due to lack of basic sanitation. Globally, investing in water and sanitation would add 1.5% to the GDP with a 4.3 return on every dollar invested in water and sanitation services. Considering the baseline,[2] returns on investment in Africa are undoubtedly higher.

Over and above the economic returns, co-benefits such as higher productivity in agricultural, commercial and industrial enterprises due to improved workforce participation would be enormous. The other side of the equation is real savings from avoided medical-related costs and lost productivity due to worker absenteeism. Self-evidently, delivering sanitation and hygiene in Africa is no brainer.

More, better managed and targeted investment is required if African countries are to attain clean water and sanitation goal (SDG 6) of ensuring availability and sustainable management of water and sanitation for all by 2030. Currently, total investment in water and sanitation is woefully inadequate. Globally, private sector participation in the water and sanitation sector, for example, accounted for only about 5.4% of the gross value of private investments in infrastructure during the 1990s.

According to a World Bank Report, at its peak in 1997, private participation in the water supply and sanitation sector brought US$9.4 billion in investment to emerging markets, approximately one third of the estimated amount needed to meet the Millennium Development Goals. By 2002, private participation in this critical sector had fallen to US$1.9 billion (Baietti and Raymond, 2005)[3].

Private sector financing needs to be ramped up to complement the water- and sanitation-related official development assistance that is part of a government-coordinated spending plan. To be clear, financing is only one side of the equation. The other side which is related to political, legal, and contractual risk is just as important. Meaningful partnership between public and private sector is therefore as desirable as it is unavoidable.

Going forward, mobilisation on a massive scale will be crucial in ensuring sufficient financial and technical resources capable of dramatically increasing the proportion of the population using (1) safely managed drinking water services, and (2) safely managed sanitation services, including hand-washing facility with soap and running (sic) water.

Furthermore, enhanced action is urgently needed in terms of the proportion of wastewater that is safely treated as well as proportion of bodies of water with good ambient water quality.

In terms of demand management, there needs to be a significant change in water-use efficiency over-time.



[1] Human right to water and sanitation is explicitly recognized by the United Nations General Assembly through Resolution 64/292.
[2] Seventeen African countries, including Benin; Burundi; Comoros; Democratic Republic of Congo; Republic of the Gambia; Kenya; Liberia; Libya; Malawi; Mali; Morocco; Mozambique; Niger; Nigeria; Uganda; Zambia; and Zimbabwe have signed up for voluntary national review (VNR) that will give a status report on trajectories towards realisation of sustainable development goals. The VNR presentations which are planned to begin on Monday, 13 July 2020 as part of the high-level political forum on sustainable development under the auspices of the Economic and Social Council will hopefully provide up-to-date picture of where countries stand.

Mobility in a post-COVID-19 world: Choices and consequences


People will be forced to make difficult choices between using private or public transport as economies begins to move out of the now ubiquitous stay-at-home lockdowns. In an ideal world where public transport is a realistic option, people would prefer to use public transport as the mode of choice from a social welfare standpoint.

But, due to social distancing measures that now appear likely to stay in place for the foreseeable future, individuals would be incentivised to use private transport modes (e.g., private cars for commute). It is reasonable to assume that in a post-COVID-19 world shared ridership will not be an option for the simple reason people should prefer private to public transport (i.e., for fear of contracting the disease). In effect, this should shift mobility systems farther away from sustainable low carbon modes of transport.

However, for the majority of people around the world the choice between public and private transport simply does not exist for a number of reasons. The obvious one is the fact that for many families owning a car is impossible given their level of income (Fig. 1). Or there is simply no provision for public transport as is the case in many countries.[1] Or if it exists, it is unaffordable.


In theory, individuals have a choice either to walk or use any other form of non-motorised transport – NMT (e.g., bicycle, particularly where cycling is a realistic option).  NMT is regarded as healthier and environmentally friendlier - even though it is worth mentioning that cost (time and distance), as well as personal safety, are the primary considerations in majority of commuting choices.

The advent of the novel corona virus that causes COVID-19 heralded a new normal in mobility. Whilst personal safety has always been a concern for the commuting pubic, henceforth it is likely to be much more significant a factor. This situation is not likely to change until such a time when there will be a vaccine available, or society would have built herd immunity to allow pre-COVID-19 mobility patterns to resume.

My hypothesis is that self-preservation instincts and the rules of the game as defined by public authorities will be the main determining factors in mobility choices going forward. This would be tragedy in the sense that the decarbonisation dividend[2] observed under the stay-at-home lockdown orders imposed in cities and regions around the world could easily dissipate. That would turn the Paris Agreement ambitions[3] on their head. With that said, a pertinent question is to ask would be: what should be done to minimise the likelihood of such reversals happening?

Of course, none of the above is inevitable. Given that most countries are going to suffer severe recession, or deep depression through at least 2022, the slowing down of economic activities globally could mean less emission. If countries are able to clearly define pathways and mitigation actions to decarbonise transport in their second Nationally Determined Contributions, they can count on extending the decarbonisation dividend resulting in significant reduction in global emissions.[4]

A well-thoughtout and transformative pathways towards greener carbon neutral economy is a smart way to reimagine economies and innovate ways out of the hole countries find themselves in thanks to the coronavirus pandemic.

Admittedly, this is rather optimistic in an increasingly polarised world. However, a valuable lesson from COVID-19 is that the world should, and indeed must, be better prepared to deal with emerging crises such as climate change.


[1] An extreme but tragic example is the case of migrant workers in India who were forced to walk back to their homes (rural villages) since there was no alternative means of transport due to the COVID-19 lockdown in the cities. Fatigued from walking for 36 kms, 16 people are reported to have crusted to death (https://www.bbc.com/news/world-asia-india-52586898) as they slept on rail tracks in the state of Maharashtra due to exhaustion.   
[2] Decarbonisation dividend refers to the observed reduction in carbon emissions directly as a result of COVID-19 induced stay-at-home lockdowns orders and closures. This has been a boon for climate change and sustainable development.
[3] Under the Paris Agreement, countries pledged to transform their development trajectories through Nationally Determined Contributions (NDCs) i.e., post-2020 actions by each country to reduce national emissions and adapt to the impact of climate change.  Several initiatives and solutions aimed at developing sustainable mobility systems to catapult society towards greener and healthier ways to move around are currently underway.
[4] According to the International Energy Agency (IEA), transportation is responsible for almost one quarter of direct CO2 emissions from fuel combustion. Road vehicles – cars, trucks, buses and two- and three-wheelers – account for nearly three-quarters of transport CO2 emissions.
