Essay submission day

I usually get a chorus of cheers at the start of the first semester from my Grade 12 biology students when I announce that there will be just one major homework assignment for the whole semester. Strangely these cheers soon change to groans when I tell them that the assignment is a 1500 word fully cited and referenced academic essay!




The rationale

I am aware that there is a continuing debate going on around whether teachers should be setting homework at all, and a few of the opposing viewpoints are summarised nicely here. Some research suggests that whilst homework may not have much effect on achievement for younger students, for high school students it can have beneficial effects on achievement. I will return to homework in a future blog post - for now I will focus on these essays & why I assign them. The rationale for this activity is that my students will shortly be going to university, and many of them will need to use academic writing skills, whatever degree subject they choose to pursue. They will also need to carry out independent research and find relevant articles and background information for themselves. Thus this essay task gives them an opportunity to gain some experience in these areas. This is not an easy task for my students since they are Thai and therefore learning (and writing) in their second language. 

The work

Before setting the essay itself, I assign three very short pre-essay tasks to give my students the opportunity to practice three important skills: paraphrasing, summarising, and the correct use of in-text citations. These tasks are awarded a simple completion grade; the main purpose is to get learners familiar with these skills. 

For the essay itself, there are some important points to note. Firstly, although it is first and foremost a biology essay, students have complete freedom to choose any topic with a biological focus. Many students choose to do a 'pure' biology essay. Other students, who may be less interested in biology, are able to choose a different approach, for example bioengineering or biochemistry. Another popular choice is to take a psychology-oriented approach, for example I have previously received essays about the psychology of sleep, and one about how the teenage brain affects teen behaviours. I think it is important for students to have this level of choice since this is a major piece of work which they will need to spend some time with - hopefully if they choose to write about something they are already interested in it will increase their engagement with the task. From my point of view it also makes the task of grading the essays far more enjoyable by having a set of completely different essays, rather than the same topic appearing repeatedly. 

The second point to note is that I give my students a time frame of three months to write the essay. They are free to submit their essay at any point during these three months, although they are informed that it will not be graded until everyone has submitted their work. This is an attempt by me to minimise deadline bottlenecks for my students at the end of the semester. Of course, being teenagers, I generally get fewer than ten percent of the essays submitted earlier than the deadline!

Thirdly, I make it very clear to students that plagiarism will not be tolerated. Very occasionally I have had to return work to students ungraded, and ask them to re-submit an essay that has not been extensively copied and pasted. I even had a student submit work that came from a website that claimed it wasn't a cheat site, but a collaborative one, when it clearly was simply in the business of selling complete essays. Fortunately these cases are rare, and the vast majority of students do a good job and are careful to fully cite and reference their work. 

Some examples

Each year I look forward to seeing the diversity of topics chosen by my students. The range of diversity can be seen in some of this year's list of essay titles, which, in no particular order, are: 

  • Life in the underwater world
  • Why do we die?
  • Bird migration
  • Infectious disease
  • Stem cells
  • The fatal Ebola
  • Viruses
  • Biodegradable plastics
  • The digestive system
  • Biological weapons
  • DNA profiling
  • Cancer treatment
  • The meaning of animal behaviour
  • Plant diversity and evolution
  • The classification and evolution of dinosaurs
  • Coronary surgery
  • How does Golden Rice help vitamin A deficiency?

Summary

As already mentioned, my students are Thai and therefore a task such as this is particularly challenging for them. However, it is clear from the generally high standard of essays that I receive from my students that they put a lot of time and effort into these essays, and I am frequently pleasantly surprised at the insights and thoughtfulness displayed in some of their work. Although there is some (generally!) good-natured grumbling about the task, I think in the end my students can see the benefits of doing this work.

Extended scientific writing with EALs

This week I will be assigning the major piece of coursework for my Grade 12 students this semester – a 1500 word scientific essay, on a biology topic of their choice. This is a challenging activity for my learners, given that they are EALs. However, I feel it’s a great way to have them practice important transferrable skills that will be invaluable to them when they go to university next year. Some of my learners will go on to study in the UK or the US, while many others will take up places in international programmes in Thai universities where the medium of instruction is English. Academic writing, paraphrasing, and the correct use of citations and referencing, are skills that most, if not all of them, will likely be facing in the coming years.

I hope that by giving learners free reign in terms of choosing their topic, it goes some way to lightening the burden of this task. They can choose any topic they like relating to biology. For those who may be less interested in biological sciences as a subject, or will not be pursuing a degree in that field, I will accept essays with a biology angle. For example, in previous years I received essays based on biomechanical engineering and sleep deprivation studies, which obviously lean more towards engineering and psychology, respectively.

Before getting started on the essay itself, I set a couple of pre-essay activities. These give learners an opportunity to review and practice a number of key skills I am hoping to reinforce with this assignment. The first pre-essay activity involves the correct use of in-text citations and references. The second gives learners a series of short extracts from primary scientific literature that they must summarise and paraphrase. They are also expected to find an example of a recent research article of their own and write a two or three sentence summary of it.

Grade 12 students here in Thailand have an awful lot of pressures piling up on them during this, their final year of school. Many of them will be preparing for and sitting multiple exams, for example SATs and university entrance exams. Therefore I do not assign a lot of homework, with this essay being their one major task to be done outside of class time. As a result, the deadline for this work is two months from now, in early September. I also make it clear to my students that they are free to submit their essay at any time between now and the deadline. This is partly to help them avoid the typical bottleneck of deadlines that build up at the end of term. However, teenagers being teenagers, I can count on one hand the number of essays that have been turned in much before the deadline in the past!
