# The Effect of Class Size to the Teaching and Learning of Mathematics

Contents

## 1.2 Statement of Problem

In view of the geometrical increase in students enrollment in our secondary schools with corresponding arithmetic increase in the staff strength, the research is worried on 1. How teacher can manage and teach a class with many students of about 40-60? 2. Do teachers in large and small classes differ in time spent on teaching or instructional activities overall, time in individual, group, and class contact and individual attention from teacher? 3. Can the teacher cope with proximity ie can the teacher go with the students individually. 4. Do teachers in large and small classes differ in more qualitative dimensions of teaching, concentrating

## 1.3 Purpose of study

Since the teaching and learning of mathematics is affected by class-size, it then becomes pertinent to; 1. Find out if students learn more when the class size is between 25-30 students or If they learn more when the class size is above the 25-30 students. 2. Find out is teachers do teaching more effectively when the class-size is between 25-30 students or above and Find out if the students receive maximum attention and supervision from the teacher when the class-size is between 25-30 students or above.

This is with a view to identifying the problem of large class-size ie 40-60 students and possible give necessary suggestion for improvement.

## 1.4 Significance of the Study

The study will be beneficial to this groups:

1. To the students.

2. To the teachers.

1. The research will expose the students to see reason in what they are supposed to be doing and needs to receive maximum attention and supervision at all time. Above all, it will enable them to understand, appreciate science, live meaningfully and effectively especially in this age of science and technology.

2. The research woke will also enable the teachers to know their students problems and help in solving their problems. At the sometime give students the correct assessment as and when the need arises. This will expose the teachers of the needs to follow the stipulated policy of student per teacher ratio (ie students/teacher ratio) as stipulated in the national policy of Education.

## 1.5 Scope of Study

Four secondary schools in Enugu North Local Government Area of Enugu State were taught these topics (1) Statistics (2) Probability.

## 1.6 Research Questions

1. Do students learn more with the class size of 25-30 students and above, using mean achievement scores and standard deviation, of the control group 40-30 students in pre and post mathematics achievement test?

2. Do students receive maximum attention and supervision from teacher when the class size is between 25-30 students and above, using mean achievement scores and standard deviation of control group 40-60 students and experimental group of 25-30 students in pre and post mathematics achievement test due to sex?

FINDINGS

1. There is significant difference between mean achievement scores of students in the experimental and control groups in pre mathematics achievement test.

2. There is significant difference between the mean achievement scores of students in experimental and control groups in post mathematics achievement test.

3. There is significant difference between mean achievement scores of students in the experimental and control groups in post mathematics achievement test due to sex.
