Metacog-what?

Goals:
Articulate the benefits of metacognitive reflection.
Identify the characteristics of a good metacognitive reflection writing.
Engage in productive metacognitive reflection about their badge work.

Agenda:
Upload
Warmup
Reading/Discussion
Deconstruct Exemplar
Write

Download:
Metacognitive Reflection Handout - Open in Notability

Warmup
Complete “Before” column of the anticipation guide, noting if you agree or disagree with each statement.

Reading/Discussion
What is metacognitive reflection? Why do the badges require metacognitive reflection?

In the Metacognitive Reflection Handout:
1. Read the article, “The Role of Metacognition in Learning and Achievement” and annotate with those two questions in mind.
2. Complete think-pair-share discussion to answer the previously posed questions. During this they complete the “Think-Pair-Share” graphic organizer. Share your thoughts with the class.

Deconstruct Exemplar
Read and highlight the Example Metacognitive Reflection, following the directions in the Metacognitive Reflection Handout.

Upload
Make sure the following things are uploaded to Badgelist Analytical Techniques 2. No reflections needed

Process:
1. Tutorial - you made this last week
2. Concentrations Calculations Work - Screenshot Page 14 of the packet showing the calculations you did to prepare your stock and dilutions of your standards for the Bradford Assay lab.

Product:
Standard Curve + Calculations - Upload a photo of your standard curve from the Bradford Assay Lab and the calculations you did to approximate the concentration of the unknown protein sample. You can just screenshot Step 6 parts B and C from the packet.

Write
Write your metacognitive reflection for the Analytical Techniques 2 badge using the prompts I give you. Make sure to answer ALL questions.

Closure
1. Complete the "After" column on the anticipation guide, noting if you agree or disagree with each statement.
2. On the back, please provide feedback on the new badge reflection.

  • Are they better or worse than before? 
  • What do you like? 
  • What needs improvement?

While I'm Away...

Goals:

  • Describe how to operate a spectrophotometer to find  λmax and absorbance values of a given solution. 
  • Define concentration in terms of solute, solvent, and solution. 
  • Perform calculations using  C=m/V.
  • Calculate the concentration of a dilution using C1V1=C2V2.

This blog post will be your go to guide for Wednesday-Friday
Over the course of the 3 days, you will need to complete the 2 assignments below (I also wrote a note on the whiteboard).


ASSIGNMENT 1: SPECTROPHOTOMETER TUTORIAL
Work with your elbow partner to create a tutorial. Here are some resources:

ASSIGNMENT 2: CONCENTRATION CALCULATIONS
Complete pages 8-13 of the packet.
  1. Go through the slides on your own and use them to complete the notes on pages 8-10 and 12 in the packet. 
  2. Complete the practice problems on pages 11 and 13 of the packet. 
  3. Check your answers on the answer key I left with the sub. 



EARLY FINISHERS
Should do academic recovery to clear NMs or study for upcoming competencies.
