PENGARUH MODEL PROBLEM BASED LEARNING (PBL) BERBANTUAN MEDIA SMART BOX TERHADAP KEMAMPUAN BERPIKIR KRITIS SISWA PADA MATERI WARISAN BUDAYA

Popi Pramudita — 2026-07-31

_{Critical thinking is one of the essential competencies that
elementary school students should develop to meet the demands of
21st-century learning. However, classroom observations at SD
Negeri Ambit revealed that students' critical thinking skills remained
low because learning activities were still teacher-centered and
lacked engaging instructional media. This study aimed to determine
the effect of the Problem-Based Learning (PBL) model assisted by
Smart Box media on students' critical thinking skills in cultural
heritage learning. This study employed a quantitative approach using
a Pre-Experimental Design with a One-Group Pretest–Posttest
Design. The participants consisted of 20 fifth-grade students
selected through saturated sampling. Data were collected using five
validated and reliable essay questions and analyzed through the
Shapiro–Wilk normality test and Paired Sample t-test. The results
showed that the mean score increased from 33.5 on the pretest to
75.5 on the posttest. The hypothesis testing indicated a significance
value of 0.000 (p < 0.05), demonstrating that the implementation of
Problem-Based Learning assisted by Smart Box media significantly
improved students' critical thinking skills. Therefore, this learning
model can be considered an effective instructional alternative for
improving critical thinking skills in elementary school I PAS learning.}

Reading literacy skills are a key foundation in basic education, especially for lower grade elementary school students (Grades I–III) who are in the crucial early stages of reading development. However, many students still experience persistent difficulties in reading, which ultimately negatively impacts their academic achievement and overall learning development. This literature review study aims to comprehensively analyze and examine the internal and external factors that contribute to low reading literacy skills in lower grade elementary school students. The methodology used is a systematic literature review approach, which is carried out by collecting, synthesizing, and critically analyzing various scientific literature sources and relevant previous research results. The results show that low reading literacy skills are driven by two main interrelated dimensions. Internal factors include low interest and motivation in learning, limited intellectual ability of students in processing text information, and unstable psychological and emotional conditions of children. Meanwhile, external factors include a lack of conservation and consistency of parental involvement at home, teachers' pedagogical roles and insufficiently varied learning strategies, limited availability of appropriate literacy facilities, and excessive and uncontrolled use of digital devices. Ultimately, this study concludes the importance of building active collaboration between parents and educators, supported by the provision of adequate literacy resources, in order to effectively improve students' reading literacy skills from an early age.

This study was motivated by the need for more visual, contextual, and motivating media in teaching anecdotal text writing. It aimed to describe the preparation, implementation process, and learning outcomes of using Cartoon Comic Strip Maker in teaching anecdotal text writing to Grade X students at SMAN 2 Cimalaka in the 2024/2025 academic year. The study employed a pre-experimental one-shot case study design supported by classroom observation data. The research subjects were students of class X-3; complete post-test data were obtained from 25 students because five students were absent. The instruments included a teaching module, an observation sheet, an anecdotal text writing task, and an assessment rubric covering four aspects: text structure, language features, comic visualization, and creativity and originality. The findings indicate that the learning preparation was systematically developed through a teaching module, student worksheet, learning materials, and assessment rubric. The learning process was implemented effectively through activities involving text comprehension, application feature exploration, idea development, transformation of written anecdotes into comic strips, presentation, feedback, and reflection. The post-test results showed a mean score of 82.32, with the highest score of 96, the lowest score of 60, and 20 out of 25 students (80%) achieving a score of 75 or higher. Therefore, Cartoon Comic Strip Maker is feasible as an alternative instructional medium for teaching anecdotal text writing, although causal claims remain limited because the study did not employ a pre-test or a control group.

This research is motivated by the low interest in learning and critical thinking skills of students in the science subject of map recognition. This problem is caused by the lack of application of learning models that actively involve students and the suboptimal use of interesting and innovative learning media. One of the efforts made is to implement a cooperative learning model of the Student Teams Achievement Division (STAD) type assisted by digital map puzzle media. This research aims to increase students' interest in learning and critical thinking skills through the application of this model. The method used is Classroom Action Research (CAR) with the design of Kemmis and Mc. Taggart which was carried out in two cycles. Data collection techniques include tests and non-tests with instruments in the form of critical thinking ability test sheets and student learning interest questionnaires. The results of the study showed an increase in both aspects studied. Students' interest in learning in the high category increased from 14% in the initial data to 89% in cycle I and 93% in cycle II. Students' critical thinking skills also increased, indicated by the percentage of learning completion from 14% in the initial data to 64% in cycle I and 93% in cycle II. Thus, the application of the STAD type cooperative learning model assisted by digital map puzzle media has been proven to increase learning interest and critical thinking skills of fifth grade students of SD Negeri 4 Mekarasih in the material on recognizing maps.
