Method of reviewing Biology theory

To grasp the theory firmly and remember it accurately, students need to systematize knowledge in the form of mind maps, review through comprehensive questions...

With Biology being a theoretical subject with 60% of the questions in this section, to achieve high scores, students must first recognize how the question trends change. What is the most effective review method?

Cross-sectional questions, exploring the nature and practical applications

Looking back over the years, the trend of Biology theory questionsis changing towards more and more sentences linking parts, exploiting the nature of specific knowledge of Biology and especially practical question types.

Example: (Illustrative test 1 of the Ministry of Education and Training in 2017)

Which of the following measures contribute to the sustainable development of natural resources?

(1) Maintain biodiversity.

(2) Use forest land for farming.

(3) Exploiting and rationally using renewable resources.

(4) Control population growth, strengthen education on environmental protection.

(5) Increase the use of chemical fertilizers in agricultural production.

A. (1), (3), (4).

B. (1), (2), (5).

C. (2), (4), (5).

D. (2), (3), (5).

Answer: A

Sentences that count the number of true and false statements appear more and more frequently.

A trend in making questions is that because the exam is limited to 40 questions, in order to test a lot of knowledge, the type of question that counts the number of true and false statements appears more and more. If this type is not thoroughly practiced, the probability of making a mistake is very high.

Example: (Test questions of the Ministry of Education and Training)

When talking about gene mutations, how many of the following statements are correct?

1. Mutations that replace a nucleotide pair always lead to premature termination of the translation process.

2. Gene mutations create new alleles that enrich the gene pool of the population.

3. Point mutation is a type of gene mutation involving a single nucleotide pair.

4. Gene mutations can be harmful but can also be harmless or beneficial to the mutant organism.

A. 2.B. 3.C. 2.D. 4.

One thing to note is that correct clause counting questions usually have no more than 5 clauses. Since 40 questions are only done in 50 minutes, this trend is becoming more and more realistic.

Review method

So what is the effective review method when there is only about a month left to review the entire program?

First, students need to systematize knowledge, using the mind map method. Then the ability to think, synthesize and logic will increase quite quickly. Thereby, reviewing becomes more interesting and effective, especially without fear of missing knowledge.

Depending on the amount of each part, you can systematize it with one or more mind maps.

For example: When reviewing a particularly important section - AND duplication

After reviewing knowledge in the form of mind maps, practice is very necessary. You should practice with questions that require interdisciplinary knowledge and application.

Example: (A question using multi-part knowledge: genetics, evolution, ecology)

When talking about evolution according to Darwin's theory, there are the following statements:

(1) Individual variation refers to the differences between individuals of the same species that arise during the individual life of an organism.

(2) Under the influence of natural selection, the gene pool of the population changes in different directions over time, forming adaptive characteristics on the organism's body.

(3) The driving force of artificial selection is the struggle for survival.

(4) The supportive relationship between individuals in a population is the driving force of evolution.

How many statements are correct?

A. 3.B. 0.C. 2.D. 1.

Instructions: Consider the statements of the topic:

(1) Incorrect because individual variation refers to differences between individuals of the same species that arise during reproduction, not during the individual life of an organism.

(2) Wrong because Darwin did not know the concept of population gene pool. This is the concept of modern genetics.

(3) Wrong because the driving force of artificial selection is human needs and tastes. The driving force of natural selection is the struggle for survival.

(4) False because competition between individuals in a population is the driving force of evolution.

So none of the above statements are correct → Answer B

Thus, to review effectively, students need to clearly understand the question trends, the knowledge to review and especially the review methods.During the review process, students should combine it with practicing comprehensive tests to be able to coordinate knowledge parts more smoothly.
