  1. So I was looking at past papers and I saw this question in Nov 16 "Explain how one principle that defines BLOA has been demonstrated in one example of research" simple question right? Then, the mark scheme says "acceptable principles may include, but are not limited to: 1)patterns of behavior... 2)animal research 3)Biological correlagtes to behaviour..." What do they mean by "not limited to"? Aren't these the only principles in BLOA? Does it mean students can invent their own principles if they want to? Wouldn't that be very difficult to mark? What is an acceptable principle? Thx.
  2. In my biology IA, I am using a statistical test called the one way ANOVA test. However, this test is overwhelmingly complicated that it would take ages for me to do all the calculations and showing them in the form of tables. Being in Y12 now I simply don't have that much time to dedicate hours into writing 8 pages of statistical calculations. So my question is can I use an online calculator? Can I simply reference the website in the report and say "due to the complexity of this test an online calculator was used." ? Will it influence my "personal engagement" criteria? Thank you very much!
  3. Thank you very much! My fault for saying "7 overall", I did mean "A" instead of "7".
  4. I have many assignments due in a short amount of time and I don't want to spend too much energy on TOK essay. I just want an overall 7 for TOK and I will be satisified with that. So how many marks do i have to get in the essay if I want a 7 overall with the precondition that I got a 10 in the presentation? Thank you!
  5. I am currently doing my Biology IA. I calculated the Mitotic index of six onion root tips for five different areas from top to bottom: root cap, mitotiz zone, elongation zone, and maturation zone. Now, I want to use a statistical test to show that there is a general significant difference between the five groups' mitotic index. I decided that an ANOVA (One-way analysis of variance) test will be approriate because it calculates differences between more than 2 groups of data. However, I don't know if IB will allow me to use this test because i heard IB may have restrictions on what kind of statistical test students can use. Does anyone know if such rule exist? If it does exist, then what other statistical tests maybe approriate for my IA? Thank you
  6. I couldn't say, to be honest, as I have no study guide. If you use both of them at the same time, you should have all the content you need and then some. Personally, however, I feel like my textbook plus online resources are good enough to learn from. The workbook's probably good practice, though (personally) I'd use it closer to exam time and go over the answers without looking at the content. It'd be a good way to see how much you remember. Thank you!
  7. Do you think it is better to review with this book or follow the allot study guide? I saw some note and summaries in the sample, are they structured and informative?
  8. Has anyone bought the 'Biozone student workbook' for HL biology? Looking at the sample pdf, it seems like it has a lot of practice questions plus all the summary on all syllabus point(no nature of science). It seems like that it is even more concise and informative than the famous 'IB biology study guide' by Oxford. However, i only looked at a sample. Did anyone actually bought the book? How do you think about it? Do you recommend it? Thank you.
  9. Thank you very much! Thank you, this is very helpful!
  10. I saw what so called nature of science everywhere on my biology study materials, and they are also in the IB Biology study guide. However, after I quickly look through these 'nature of science', I found they are just some pretty random ideas packaged with some pretty random examples. If nature of science will appear on the exam, does that means I have to remember certain scenarios?
  11. Hi! I am stuying IB in Australia and I am interested in computer science. However, I am not very good at math (I chose math sl) so I am a bit worry about all the math contents in computer science. On the other hand, I have been self-studying java programing for quite a long time, so I guess I know something about the programing side of computer science. Could you please give me any suggestion about a better decision? Should I go for software engineer instead of computer science? Thank you.
  12. film sounds interesting and easy for many people, but actually is not. When you do in depth film study it will be as difficult as any other ib sujects. Considering the fact that you never study film and it seems like you dont have a fim study supervisor, I reconmend you not to do this EE.
  13. Sorry if the post looks a bit confused. It is basically about observing and estimating the population of diffrent types of cirripedia on a rock shore and see whether they distribute in a regular pattern or not.
  14. Hello guys, thank you for reading this post and please help me if you have any ideas. I decided to do a Biology EE, and the topic is "Observation of the distribution of different types of Cirripedia (a type of shell like insects living on rock shores all around the world) on the rock shore of Bondi Beach, New South Wales, Australia." In this investigation, I will observe six types of cirripedias, and see where do each of them settle down on a rock shore. Some specific questions in the EE could be "Are there any regular patterns of the distribution of different types of Cirripedia on a rock shore?", "Can the distribution of different types of Cirripedia enable scientists to determine the tidal zone of a rock shore area?" However, eventhough I have a topic and some ideas, I do not know exactly how to specifically carry out this experiment. I also do not know if this topic is suitable for an EE or is it better for an IA. Please write some comments if you have any suggestions. Thank You!
