RE: Research Question and Title of Extended Essay
Please note the statement below from the EE curriculum manager regarding the need to have both a title and a RQ for all subjects. Previous versions of the EE Guide indicated that the title and the RQ should be the same for History, Business Management and Mathematics. This is no longer the case. All essays, regardless of the subject, need to have both a RQ and a title.
Hi Kathy,
To answer your question, I am going to quote directly from a response John Royce provided, on this forum, in October in response to a very similar question: (it was a question about using Spanish sources - hence the mention of Spanish)
It is certainly permissible to use sources which are not in the language of the essay, but translation into the target language is required , one cannot assume that the reader understands the original language.
It is usual to quote the original as well as presenting the translation. [Do not put quotation marks around your translation, just around the original]
Umberto Eco argues ("in Mouse or rat?") that direct translation may lose meaning, paraphrase or use of different idioms may be required to get the ideas across. Paul Bellos ("Is that a fish in your ear?") makes a similar argument - direct translation may confound meaning... Direct translation may not be ideal - meaning and understanding are preferred - so, not to worry that your student with her good Spanish cannot present a direct translation.
What must be made clear is that the translations are those of the student; these are her understandings. Readers can make of that what they will - and if unsure, are presented with the original - they can seek another translation. A note in the acknowledgements and/or in the introduction to the effect that all translations are those of the writer is ... essential.
In response to the question about the Bibliography/Works cited, my preference would be to list the source in its original Thai version, but perhaps with the English in brackets, to help the examiner.
Your bibliography will have the entries in Thai characters first in the document. Any in-text citation to Thai sources will be in (Thai characters [English translation]).
Citation in Thai [English translation]
Works Cited Example:
วงษ์ปัญญา, ธนกร [Wongpunya, Thanakorn]. “โรงงานยาสูบรวยแค่ไหน และเอาเงินไปทำอะไรบ้าง.” [How rich is the Thailand Tobacco Monopoly and where does the money go?] (candidate translation). The Standard, The Standard, 30 Aug. 2018, thestandard.co/thailand-tobacco-monopoly/.
Required Formatting
The extended essay should be written in a clear, correct and formal academic style, appropriate to the subject from which the topic is drawn. Given that the extended essay is a formally written research paper, it should strive to maintain a professional, academic look.
To help achieve this, the following formatting is required:
Submitting the extended essay in the required format will help set the tone of the essay and will aid readability for on-screen assessment by examiners.
Required S tructure
The structure of the essay is very important. It helps students to organize the argument, making the best use of the evidence collected.
There are six required elements of the final work to be submitted. More details about each element are given in the “Presentation” section. Please note that the order in which these elements are presented here is not necessarily the order in which they should be written.
Six required elements of the extended essay:
1. Required Title Page
The title page should include only the following information:
The upper limit is 4,000 words for all extended essays.
2. Required Contents Page
A contents page must be provided at the beginning of the extended essay and all pages should be numbered. Please note that an index page is not required and if included will be treated as if it is not present.
3. Required Introduction
The introduction should tell the reader what to expect in the essay. The introduction should make clear to the reader the focus of the essay, the scope of the research, in particular an indication of the sources to be used, and an insight into the line of argument to be taken.
While students should have a sense of the direction and key focus of their essay, it is sometimes advisable to finalize the introduction once the body of the essay is complete.
4. Required Body of the Essay (research, analysis, discussion, and evaluation)
The main task is writing the body of the essay, which should be presented in the form of a reasoned argument. The form of this varies with the subject of the essay but as the argument develops it should be clear to the reader what relevant evidence has been discovered, where/how it has been discovered and how it supports the argument. In some subjects, for example, the sciences, sub-headings within the main body of the essay will help the reader to understand the argument (and will also help the student to keep on track). In structuring their extended essay, students must take into consideration the expected conventions of the subject in which their extended essay is registered.
Once the main body of the essay is complete, it is possible to finalize the introduction (which tells the reader what to expect) and the conclusion (which says what has been achieved, including notes of any limitations and any questions that have not been resolved).
Any information that is important to the argument must not be included in appendices or footnotes/endnotes. The examiner will not read notes or appendices, so an essay that is not complete in itself will be compromised across the assessment criteria.
5. Required Conclusion
The conclusion says what has been achieved, including notes of any limitations and any questions that have not been resolved. While students might draw conclusions throughout the essay based on their findings, it is important that there is a final, summative conclusion at the end. This conclusion(s) must relate to the research question posed.
6. Required References & Bibliography
Students should use their chosen style of academic referencing as soon as they start writing. That way they are less likely to forget to include a citation. It is also easier than trying to add references at a later stage. For more information on this, refer to the guidelines in the IB document Effective citing and referencing.
Writing the essay takes time but if students have used their Researcher's reflection space and reflection sessions in a meaningful way they should be well prepared to develop their arguments.
