Reflection about a Chemistry Teacher in Grade 10
As we know, Bloom classified levels of thinking into six:
1- Remember
2- Understand
3- Apply
4- Analyze
5- Evaluate
6- Create
After
observing the explanation of this Chemistry teacher, it was clear that the
teacher has followed “Bloom’s Taxonomy” in presenting the lesson for the class.
This stands for the levels of thinking of both “teacher and students”. When the
teacher started with a new type of reactions which was “redox”, he was aware to
recall the definition of a reaction. What is a reaction? So by this way the
teacher depend on the first level of thinking “knowledge”.
In addition, when the teacher explained the
method of calculation for the oxidation number of Cr in Cr2O72- . The
teacher asked a student to rephrase the method (how we get the oxidation number
of Cr) in his own words. By this strategy, the teacher was following the second
level of thinking “comprehension”.
When
the ideas were stated clear in a detailed way for students, it is the time to
have a solving session including the indication of the oxidation number of
various molecules, then going to another question about stating whether the
reaction is redox or not and this is based on indicating the oxidation number
of the reactants and products firstly. Such
practice refer to “application”, the third level of thinking in Bloom’s
Taxonomy.
Then the teacher suggested for students to create a question designed in the way as the
previous ones. The given was to make a reaction between Mg and CO2. So
in this way, students will be able to generate a question including the main
ideas of the discussed material. Such way refers to the fifth level of thinking
“synthesis”.
People
need to be professional in their work, completeness is never reached. But
everyone must work more to reach high levels, a kind of idealism. This requires
from the teacher to have different levels of thinking that are known by
“Bloom’s Taxonomy”. As the Chemistry teacher uses these in her class, the
teaching method becomes more unique and more effective. This leads for better
results in education where students achieve more success. Following these
levels of thinking benefit by helping the teacher in preparing the lesson for
the students and in expressing the idea in a professional way. The more the
teacher uses these levels of thinking in the teaching and learning process, the
better results will be achieved in the class.
It is very important to use Bloom's and Anderson's taxonomy when planning a lesson and the objectives. I wish every scientific material teacher use this taxonomy and see how would the students improve since by using it, every single detail is taken into consideration and the six levels are covered.
