Effectiveness of E-Content Module in Learning Set Language among Ninth Standard Students-Solomon Four Group Method of the Experimental Study

Article History: Received: 11 January 2021; Accepted: 27 February 2021; Published online: 5 April 2021 Abstract: Pedagogical methods are one of the Mathematics e-content modules of learning. The research question was raised what teaching method is more effective, whether the e-content module of learning or traditional teaching? Solomon four-group design of the experiment was managed. A convenient sampling technique is selected. Experiments are conducted in school students with 80 samples. Academic achievement test in the Mathematics unit ‘Set Language’ was used as a tool in the study. Bartlett’s Homogeneity of Variance Test, ANOVA, and LSD post-hoc tests are used for interpretation of data. The major finding explored was that the e-content module of learning positively influenced student achievement in mathematics when compared with the chalk and talk method of teaching. A recommendation of the result was a modern pedagogical method such as an e-content module of learning which is used by the teachers in the classroom as well as the students’ home for drills and practices.


Introduction
One of the Pedagogical methods of Mathematics is an e-content module of learning. Modern technological advancement believes the subject matters can be imported through e-content learning. Mathematics is a tool for scientific communications. The alternative to the conventional method of teaching is e-content learning in modern days. Every person in the world should learn Mathematics for his/her sustainable development and survival. Mathematics influences all subjects and fields. Mathematical knowledge can be spread as awareness for escaping scientific exploitation. Mathematics is one of the compulsory subjects up to the tenth standard of general education.

Need and Significant of the Study
Set language is a branch of Mathematics that influences other fields of mathematics such as Algebra, Functional Analysis, Topology, Statistics, etc. Everything or any group of objects and living beings are expressed through the Set Language. Most of the students feel that learning mathematics is very difficult and bore the subject through a conventional method of teaching. It is a wrong notion of mathematics. Whatever, the subject delivers through the e-content module of learning to learn easily with understanding the subject concept higher than knowledge. Human is getting knowledge without the understanding of subject matter. It is easily forgettable and not applicable in life. The e-content module easily attracts the students and provides a rich experience of learning. So, the study will be proved that e-content learning is much better than the chalk and talk method of a conventional method of teaching.

Research Questions
The following research questions are raised to accomplish the objective.
1. Are four groups selected whether they have equal homogeneity and equivalent groups or not? 2. Is the treatment of the experimental groups attaining effectiveness?

Hypotheses
The following research hypotheses are formulated.
1. There are no significant differences among the variances of the four groups.
2. There are equal achievement groups of students based on their marks of the half-yearly examination.
3. There are no significant differences between the attainments of the Pre-achievement and the Postachievement of the four groups.

Research Design
The researcher adopted a pre-test-post-test of Solomon's four equivalent groups design in this research. One control group and one experimental group with the pre-achievement tests and the post-achievement tests are managed before and after taught through chalk and talk method of teaching and e-content development module of learning respectively. The pre-test is conducted immediately after assign the equivalent groups by using the halfyearly marks. And also, the control group and experimental group with post-achievements tests only are managed after taught through the Chalk and Talk Method of Teaching and the e-Content Development Module of learning respectively.

The population of the Study
Ninth standard students in the State Board of Tamil Nadu are the population for the study. Tamil medium ninth standard students in State Board of Pudukkottai District, Tamil Nadu are the accessible population for the study. Sample Eighty 9th standard students for 4 groups are selected for conducting experiments to the experimental groups and control groups (conventional groups) through the interactive e-content development module of learning and the chalk and talk method of teaching respectively. It means 20 students in each group are selected from one Government School and one Adi-Dravidar Welfare Schools in Pudukkottai District are the sample for the study. Four groups are purposively assigned the equivalent and homogeneous groups which were considering the halfyearly examination marks of students.

Research Teaching-Learning Module
The interactive e-content module of teaching is presented for the experimental groups and chalks and talk methods teaching is taught by the class teacher.

Research Tool
The present study has used the following tool: Achievement Test in the Mathematics unit 'Set Language' is prepared and standardized by the investigator.

Analysis and Interpretation
Null Hypothesis-1 There is homogeneity of variances among the four groups. The table shows that Bartlett's value 9.1442 is less than the critical value 9.2100; its p-value is 0.0274, since the P-value is bigger than the significance level (0.01), and the null hypothesis of homogeneous variances is accepted. It means the selected four groups are homogeneous. Null Hypothesis-2 There are equal achievement groups of students based on their marks of the half-yearly examination. The table shows that the calculated F-value (0.564) is less than the critical F-value (4.0503) and the calculated p-value is greater than the chosen significant level (0.01). Therefore, the hypothesis is not rejected. All four groups are achievement groups of students based on their marks of the half-yearly examination. It means they are four equivalent groups. They are perfectly chosen based on homogeneity and equivalent groups before starting the experimental procedures. Null Hypothesis-3 There are no significant differences among the attainments of the Pre-achievement and the Post-achievement of the four groups. The table interprets that the calculated F-value (172.6929) is less than the critical F-value (4.0503) and the calculated p-value is greater than the chosen significant level (0.01). Therefore, there are significant differences among the attainments of the Pre-achievement and the Post-achievement of the four groups. It can be calculated the LSD-tests for further interpretation.

Here, confirmation of the e-Content Module of Learning is increasing the learning Set Language higher than increasing through the Chalk and Talk Method of Teaching.

Finding of the Study
(i) Conventional group-1 and experimental group-2 is the same achievement level before experimenting. (ii) The e-Content Module of Learning is increasing the learning of Set Language higher than increasing through the Chalk and Talk Method of Teaching. (iii) The inclusive pattern of education can be increasing the learning Set language superior to an exclusive pattern of education.

Discussion of the Findings
Findings-1 and 2 1. Conventional group-1 and experimental group 2 is the same achievement level before experimenting. 2. The e-Content Module of Learning is increasing the learning of Set Language higher than increasing through the Chalk and Talk Method of Teaching. The following studies are supportive of findings-1 and 2.

The Impact of E-Learning on University Students' Academic Achievement and Creativity by Zare, M. et al (2016). There is no statistically significant difference between the means of the two groups (p= 0.678) at entry-level based on the pretest scores. E-learning is effective for knowledge and creativity acquisitions among chemistry students and the greater e-learning opportunities should be provided for wider audiences.
Findings concerning Maths performance were consistent with other mobile learning studies (Hwang et al. 2015;Riconscente 2013). Mobile learning applications increase the effect of learning and enhance the process of learning (Huang et al., 2014;Wishart, 2015). Finding-3 The inclusive pattern of education can be increasing the learning Set language superior to the exclusive pattern of education. The following studies are supportive of this finding. Implementation of inclusive education for children with intellectual and developmental disabilities in African countries: a scoping review by Christiana Okyere et al (2019). Thirty articles that provided empirical evidence of inclusive education implementation were included. Eight articles highlighted practices that support the inclusion of children with intellectual and developmental disabilities. Using Bronfenbrenner's bioecological framework, findings revealed that inclusive education implementation is influenced by factors on the bio level, micro-level, meso level, and macro level.

The impact of an inclusive education intervention on learning outcomes for girls with disabilities within a resource-poor setting by Mark Carew et al (2020). Over the intervention period, girls with disabilities who participated in the inclusive education intervention obtained significantly higher English, Kiswahili, and numeracy test scores compared with a comparable group of girls with disabilities who did not participate in the intervention.

Recommendation of the Study
The e-content module of teaching and learning method is adopted in the Tamil Medium Students of the Tamil Nadu Government Schools. Many schools cannot equip with adequate facilities for delivering e-content. General Government schools are established slowly with these facilities to learn the subjects. State Government schools will be followed as educational implications of the General Government for the quality education they provide to students.

Conclusion
The experimental method is proved once again, the e-content module of learning is giving the essential support for students' learning Mathematics. They are interested, enthusiastic, and attentive learners with easy recognition and recall of the subject concepts with understanding through this method.
