Writing objectives

Assignment 2
After you have seen the critique of your paper in DB 2c, you are to submit one well written (observable) learning objective for the course you are planning to teach. Identify its level on (the new) Bloom's Taxonomy and explain why you think so. Describe the way you propose to assess the attainment of this objective and explain why. At the end, please note who served as your critique partner for this assignment.
Points to be assigned as follows:
Objective meets all four criteria listed in this week's lecture materials  0-5 points
Identification of level on Bloom's and explanation 0-3 points
Description and alignment of the assessment 0-4 points
Professional level, clear writing 0-3 points



Name of the Course-ABC’s of Chemistry

Chapter 3- Atomic number and mass number

Objective:  At the end of this chapter the students will be able to define, inter-relate and determine atomic number and mass number of an atom.
Bloom’s Taxonomy: This above stated objective falls into different categories within Bloom’s Taxonomy-Remembering (define), Understanding (interrelate) and Applying (determine). Remembering is a low level of critical thinking only in the sense that it comes first but it provides the basis for all higher cognitive activity. Only after a learner is able to recall information, is it possible to move on to the next level. Thus, defining the terms atomic number and mass number would help them retrieve the relevant knowledge from long-term memory and find the relation between atomic number and mass number (understanding). As a part of assessment, the students will also label the diagram of an atom to represent the electrons and neutrons using mass number and atomic number. This question requires students to show more in-depth understanding of the terms atomic number and mass number.

The learner at the third level, Application, solves practical problems by applying information comprehended at the previous level. Students will determine the atomic number and mass number of given atoms in the assignment. The given assessment will also help students to infer (analyze)  that, in order to calculate the number of neutrons in a given atom, both -mass number and atomic number- must be known. Analysis includes the ability to distinguish relevant information from irrelevant information. Thus, according to the Bloom’s taxonomy, they will break material into its constituent parts and determine how the parts relate to one another and to an overall structure.


Assessment: The students are required to answer the following questions. Each question is worth 2 points and a score of 8 or greater indicates the student has met the objective.
Question No Question Bloom’s taxonomy level
1) Define atomic number and mass number.(one point  for each definition)
Remembering.
2) Show neutrons and electrons in the given diagram of Carbon atom. (2 points)



 12C6

Remembering.
3) What is the relation between atomic number and mass number? (2 points) Demonstrate understanding by finding relation between the two terms.
4) From the information given, can you determine the number of neutrons in following atoms (Choose the right answer): (2 points)
a)  24 12 A                                                                
i) 12
ii) 24
iii) Can’t be determined

b) 42X                                        (2 points)                                                                    
i. 42
ii. 25
iii. Can’t be determined Application as it requires participants to know how to determine the atomic number.



Analysis because thinking about the parts of an idea and their functionality in the whole is involved (The number of neutrons can’t be calculated because atomic number is not given in the question).




There is some excellent thinking here, and some fine evaluation. The objective is rather large and probably should be divided up. You have two general Understanding level objectives and one more specific Application level objective. For example:
Define atomic number and mass number.
Describe the relationship between atomic number and mass number.
Diagram the neutrons and electrons in a given atom.
The simpler the better when it comes to objectives. The rest of what you have said is quite good and your assessment is really excellent.
