Classified Nomenclature Cards and Wall Charts as an Effective Tool in Promoting Students’ Performance

Abstract

Introduction

The taxonomy provides a basic understanding of the components of biodiversity which is necessary for efficient decision –making about conservation and sustainable use (Sunderland, 2012). Yet most of the students dislike taxonomy and feel bored not knowing why they have to study. Identifying and classifying things requiring memory is a challenge for them. Thus, to prove the use of Classified Nomenclature cards (CNC) and Wall Charts in taxonomy, the proposed research envisions the effectiveness of the teacher made Classified Nomenclature Cards and Wall Charts on the academic performance of the students.

Methods

It utilized the quasi-experimental which includes pre and post-tests design with the control group. The control group used the conventional method which pertained to the Inquiry-based in teaching Science through the use of activities in the Learner's Material while the experimental group used the Inquiry-based through the Classified Nomenclature Cards and wall charts. The respondents were the Grade 8 students at Rodolfo V. Feliciano Memorial High School. In treating the significant difference of scores, a t-test at a 1 % level of significance was used.

Results

Findings revealed that the control group obtained a mean of 7.66 while the experimental group obtained a mean of 8.40 in the pretest scores. This means that there is no significant difference in the pretest scores of the control group using the conventional method and the experimental group using the wall charts and CNC. The students in the two groups were on the same level of understanding the taxonomy before the treatments. Moreover, the posttest scores showed that the experimental group obtained a higher mean of 21. 6 than the control group with a mean of 19.4. This means that using the CNC and wall charts yielded higher scores in the posttest compared to the conventional methods.

Discussions

This signifies that respondents who were exposed to the CNC and Wall Charts performed better than the participants who received conventional method instruction using the activities in the LM. Therefore, the localized and contextualized CNC and wall charts are considered more effective than using the Learner’s Material alone.
