Abstract

ABSTRACT The water cycle is one of the science topics in elementary schools that is considered difficult for students to understand because several processes are abstract and cannot be observed directly. In addition, the limited use of learning media causes students to be less enthusiastic during the learning process. This study aimed to develop a learning medium called Diorama Hujan Buatan (DIHUBA) and determine its feasibility for teaching the water cycle concept to fifth-grade elementary school students. The research employed a Research and Development (R&D) method using the ADDIE model, consisting of Analysis, Design, Development, Implementation, and Evaluation stages. Data were collected through observation, interviews, questionnaires, and expert validation sheets involving media, material, and language experts. The developed product was also tested on students through one-to-one, small-group, and field-test trials. The results showed that the media expert validation score reached 94.67%, material expert validation 94.00%, and language expert validation 98.00%, with an average feasibility score of 95.56%, categorized as very feasible. Student trials obtained scores of 96.89% in one-to-one testing, 97.87% in small-group testing, and 97.73% in field testing, with an average of 97.69%, categorized as very feasible. Therefore, the DIHUBA learning media is highly feasible to be used as an innovative learning medium to help students understand the water cycle concept more concretely and meaningfully.

Abstract

Penelitian ini bertujuan untuk meningkatkan konsentrasi belajar IPA siswa kelas III B SDN Guntur 01 melalui penerapan model Problem Based Learning (PBL). Penelitian menggunakan metode Penelitian Tindakan Kelas (PTK) model Kemmis dan McTaggart yang dilaksanakan dalam dua siklus dengan subjek sebanyak 22 siswa. Data dikumpulkan melalui observasi, kuesioner, dan dokumentasi. Hasil penelitian menunjukkan adanya peningkatan konsentrasi belajar siswa, yaitu dari 31,82% pada tahap pra penelitian menjadi 59,09% pada Siklus I dan meningkat menjadi 86,36% pada Siklus II. Selain itu, aktivitas guru dan siswa selama pembelajaran juga mengalami peningkatan. Berdasarkan hasil tersebut, dapat disimpulkan bahwa penerapan model Problem Based Learning efektif dalam meningkatkan konsentrasi belajar IPA siswa dan penelitian dinyatakan berhasil pada Siklus II.

Abstract

Elementary science learning requires contextual activities that enable students to apply scientific concepts when addressing real-life problems. However, in-depth qualitative evidence explaining how each Engineering Design Process-based STEM (EDP-STEM) stage supports elementary students’ problem-solving skills remains limited, particularly in light and heat energy learning. This study aimed to describe EDP-STEM implementation through a solar oven project and analyze how its stages supported fifth-grade students’ problem-solving processes. Its novelty lies in mapping five EDP-STEM stages to four problem-solving indicators using multiple qualitative data sources. A qualitative case study was conducted with 26 students in four groups during eight learning sessions. Data were collected through observations, interviews, student worksheets, reflective journals, field notes, rubrics, photographs, and videos. The data were organized, coded, categorized, compared, and interpreted, while credibility was supported through source and method triangulation. Students identified insufficient heat, unstable reflectors, thick plastic covers, and uneven sunlight distribution, then proposed corresponding design modifications. Project scores ranged from 88 to 96; three groups received an A grade and one received a B grade. The clearest evidence concerned problem identification and consideration of possible solutions. Overall, the four indicators emerged through interconnected cycles of designing, testing, evaluating, reflecting, and revising.
