Evaluation Period..Next Few Classes.

Two parts to this post:

  1. In class work to be performed is listed below.
    • Collection of knowledge and reasonings
    • analysis of IB expectations
    • development of detailed proposal
  2. @Home work for Monday, October 15th 2012. [at bottom]

Part 1: 

The first step in our class summative assessment period is to reflect on the content and skills we have been working towards. The purpose of the assessment period is to reflect on the knowledge and reasoning we have been working on.

Knowledge refers to the facts, vocabulary, definitions that we are expected to know to communicate effectively about the biology we have been studying thus far. Examples:

  • stating the proper error in measurement when using a measuring tool: +/- half the smallest graduation

Reasoning refers to the application of the facts, vocabulary, definitions [etc] to describe, explain, hypothesize [apply] the knowledge we have been trying to learn to make sense of biology. Example:

  • explaining how we never/rarely know the true value of a measurement. We can only be as accurate as the tool we use within an certain range: +/- half the smallest graduation

Your work for Wednesday, October 11th, 2012, is to produce IN YOUR BLOG

  1. a detailed collection of knowledge we have been studying in IB Bioogy. Think of it as if you a producing a study sheet/notes.
  2. a list of 3 reasonings that students should be able to describe/explain to demonstrate APPLICATION of their knowledge.
  3. A DETAILED proposal on how you are going to prove/demonstrate your level of mastery on the agreed upon objectives.

The learning objectives of the IB can be found in our Moodle site at: http://sasoc.saschina.org/mod/resource/view.php?id=69430  Your job is to select the objectives you are to be summarily evaluated upon. I decide how well you have mastered the material. I’m the judge. I’m the jury. You job is to demonstrate how well you know the knowledge and reasoning collectively agreed upon.

Part 2: @Home work for October 15th 2012.

I have noticed a general weakness in remembering the structures and purpose of parts of cells. Iask you to do the following IN YOUR BLOG. [Its perfect for this type of work].

IB expects you to understand the parts of prokaryotic cells and eukaryotic cells.

  • Use the IB objectives [here again] to identify the parts of each cell type they expect you to know.
    • prokaryotic: obj – 2.2.1, 2.2.2, 2.2.3
      • i cannot find a good micrograph – do your best.
    • eukaryotic: obj – 2.3.1, 2.3.2, 2.3.3
      • plant: obj – 2.3.5
      • animal [They specifically refer to a liver cell because it is a very active, protein exporting cell that contains all the typical animal cell parts].
        • Here is a good example of a liver cell using an electron microscope. Use this Here: and select on the top left: chapter 30, select picture 8 and 10 [figures 30-8 and 30-10]
        • Be sure to appreciate the different magnification being used. 30-8 shows many cells. Some are hepatocytes [liver cells], many are endothelial cells [cells that line blood vessels]. 30-10 is higher magnification showing only a sector of the hepatocyte.
        • A resource
  • Draw each cell type in detail.
  • Label the STRUCTURES the IB curriculum demands and annotate with the FUNCTION
  • Take a picture/video of your drawings and upload into your IB Biology blog….yoohoo!
