This chapter presents the summary of the
findings, conclusions and recommendations.
1. What is the index of difficulty of the students in radical
expressions terms of the following:

1.1 Roots of real numbers. This topic has a mean index of
difficulty of 66.6, described as easy.
1.2 Expressions with rational exponents. The items under
this topic have a mean index of difficulty of 63.4 described
as easy.
1.3 Simplifying radical expressions. Items under this topic
have a mean difficulty index of 48.8 described as difficult.
1.4 Addition and subtraction of radicals. This topic has an
overall mean index of difficulty 61.4 described as easy.
1.5 Multiplication of radicals. All items on multiplication of
radicals has a mean index of difficulty 64.4 described as
easy.
1.6 Division of radicals. This topic has an overall mean
index of difficulty 61.8 described as easy.
2. What is the index of difficulty of the
students in variation terms of the following:
2.1 Direct variation. The mean index of
difficulty of these items is 49.2 described as
difficult.
2.2 Direct square variation. The items have a
mean difficulty index of 51 described as easy.
2.3 Inverse variation. The mean index of
difficulty for inverse variation is 49.4
described as difficult.
2.4 Joint variation. The mean difficulty index
of the items is 44 described as difficult.
3. Is there a significant difference in the index of difficulty of
the students in terms of radical expressions?
The computed F-value of 4.98 was greater than the
critical f-value of 2.62 using 5 and 24 degrees of freedom
at 5% level of significance. Therefore, the null hypothesis
was rejected.
This means pupil respondents have
varied index of difficulty in learning radical expressions.
4. Is there a significant difference in the index of difficulty of
the students in terms of variation?
The computed value of 2.89 was lower than the critical
value of 3.24 using 3 and 16 degrees of freedom at 5%
level of significance. Thus, the null hypothesis was
accepted. There is no significant difference in the index of
difficulty of the students in terms of variation. This means
they encountered similar difficulties in answering the
items on variations.
Based on the findings of the study, the study concluded the following:
1. The study revealed that the students found roots of real numbers
easy.
2. The results also showed that expressions with rational exponents
were easy for the students.
3. Simplifying radical expressions is difficult for the students.
4. The results suggested that addition and subtraction of radicals is easy
for the students.
5. Multiplication of radicals was found out easy by the students.
6. Division of radicals was easy for the students.
7. Direct variation is difficult for the students.
8. The items for direct square variation were easy for the students.
9. Inverse variation was difficult for the students.
10. Solving joint variation was difficult for the student-respondents.
11. The index of difficulty of the students in radical expressions varies
significantly.
12. The index of difficulty of the students in variation does not vary.
Based on the findings and conclusions, the researcher arrived at
the following recommendations:
1. Mathematics teacher should continue using their strategies in
teaching roots of real numbers.
2. The teacher should continuously give emphasis on exponents
when teaching radical expressions with radical exponents.
3. Factoring should be given attention when teaching simplifying
radical expressions.
4. Constant drills and exercises in addition, subtraction,
multiplication and division should be done to further enhance
these skills; thus, making solving easy for the students.
5. Comprehension skills, clear understanding of direct
relationship between quantities, skills to represent and operate
the unknown, analysis and problem solving skills should be
developed to make problem-solving easy for the students.
6. Future research related to this study should be conducted to
generalize the findings of this study.

The mean index of difficulty for inverse variation is 49.4 described as difficult. 2.4 Joint variation. The mean difficulty index of the items is 44 described as difficult.
  • 27. 3. Is there a significant difference in the index of difficulty of the students in terms of radical expressions? The computed F-value of 4.98 was greater than the critical f-value of 2.62 using 5 and 24 degrees of freedom at 5% level of significance. Therefore, the null hypothesis was rejected. This means pupil respondents have varied index of difficulty in learning radical expressions. 4. Is there a significant difference in the index of difficulty of the students in terms of variation? The computed value of 2.89 was lower than the critical value of 3.24 using 3 and 16 degrees of freedom at 5% level of significance. Thus, the null hypothesis was accepted. There is no significant difference in the index of difficulty of the students in terms of variation. This means they encountered similar difficulties in answering the items on variations.

  • 29. Based on the findings and conclusions, the researcher arrived at the following recommendations: 1. Mathematics teacher should continue using their strategies in teaching roots of real numbers. 2. The teacher should continuously give emphasis on exponents when teaching radical expressions with radical exponents. 3. Factoring should be given attention when teaching simplifying radical expressions. 4. Constant drills and exercises in addition, subtraction, multiplication and division should be done to further enhance these skills; thus, making solving easy for the students. 5. Comprehension skills, clear understanding of direct relationship between quantities, skills to represent and operate the unknown, analysis and problem solving skills should be developed to make problem-solving easy for the students. 6. Future research related to this study should be conducted to generalize the findings of this study.
