Abstract

Poster writing is an essential skill for students, especially in today's visual era.

Through poster creation, students are trained to think creatively, organize ideas, and

convey messages effectively and engagingly. Poster writing skills are beneficial not

only in learning contexts but also in everyday life. Based on field observations,

students experience difficulty formulating ideas or concepts, lack attractive designs,

and lack writing skills. This is due to the lack of variety in the learning models

implemented by teachers.

This study aims to describe the differences in poster writing learning outcomes

between sixth-grade elementary school students in Ganeas District, Sumedang

Regency, using the Connecting, Organizing, Reflecting, and Extending (CORE)

model with the aid of Canva and those without the CORE model with the aid of

Canva in the 2025/2026 academic year. Therefore, the instruments used were

teaching modules and tests. The method used in this study was a quasi-

experimental study with qualitative and quantitative analysis.

Based on data analysis, the success rate of poster writing learning using the CORE

model with the aid of Canva in the experimental class was categorized as high. This

is evidenced by the results of the z test which shows that z count -0.36 is located

within the interval -Z0.4900 S.d Z0.4900 or -2.33 < -0.36 < 2.33. The success rate

of learning to write posters using image media in the control class is classified as

low. This is evidenced by the results of the z test which shows that z count -2.14 is

located outside the interval -Z0.4900 S.d Z0.4900 or -2.14 > -2.33. There is no

significant difference in the ability to write posters between those using the CORE

model assisted by Canva media and those using the conventional model. This is

evidenced by the results of the t test calculation which shows t count = 1.24 which

is smaller than t0.995 = 2.66 or 1.24 < 2.66. Thus, both models can be used in
