Abstract

This study analyzes the quality of a science test instrument on inheritance, based on Higher Order Thinking Skills (HOTS) and scientific literacy, in terms of validity, reliability, difficulty level, discrimination index, and distractor effectiveness. A descriptive quantitative approach with an ex post facto item analysis design was used. The participants were 28 students, and the instrument consisted of 20 multiple-choice items developed according to HOTS and scientific literacy indicators. Validity was tested using point-biserial correlation, reliability using Kuder-Richardson (KR-20), and item difficulty and discrimination indices were analyzed through correct response proportions and comparisons between upper and lower groups. Results showed that 85% of the items were valid and 15% invalid. The reliability coefficient was 0.8827, indicating high consistency. In terms of discrimination, 60% of items were very good, 25% good, 10% fair, and 5% poor. Most items were moderately difficult (90%), and 10% were difficult, with no easy items. Overall, the instrument demonstrates good quality and is suitable for learning evaluation, although some items require revision to further optimize measurement accuracy.

Abstract

This classroom action research aims to improve the science learning outcomes of fifth-grade students at SD Negeri 09 Pontianak Barat. This study implemented a project-based differentiated learning (PjBL) approach, tailored to students' needs and characteristics. The background of this study stems from low pre-cycle learning outcomes, with a class average of 56.30 and only 29.63% of students achieving the Minimum Passing Score (KKM = 65). This study uses the Classroom Action Research (PTK) method, conducted in two cycles, each comprising planning, implementation, observation, and reflection stages. The research subjects were 27 fifth-grade students. Data collection techniques included tests, observations, and documentation. The results showed significant improvement: in Cycle I, the class average increased to 70.56 with a class mastery rate of 62.96%; in Cycle II, the class average reached 82.59 with a class mastery rate of 88.89%, exceeding the 80% success indicator. This study concludes that differentiated instruction through the PjBL model, implemented through differentiation of content, process, and product, is effective in improving students' IPAS learning outcomes. Keywords: Differentiated Instruction, Project-Based Learning, IPAS Learning Outcomes, Elementary School.

Abstract

Apparatus capable of recording time-dependent data in experiments is essential for physics learning. In this study, we developed an experimental apparatus for Simple Harmonic Motion (SHM) on a spring to record time-dependent displacement. The development was carried out by integrating an HC-SR04 ultrasonic sensor into the basic design of the SHM experiment. The study shows that, from a visual observation perspective, instead of exhibiting simple harmonic motion represented by the waveform y=Acos(ωt), the oscillator displayed damped harmonic motion characterized by a gradually shifting phase, following the waveform equation y=Acos(ωt+ϕ(t)). Focusing on the technical validation of the apparatus, both visual representation and deviation analysis indicated that the developed experimental apparatus showed good agreement with the theoretical trend, with a Mean Absolute Error (MAE) of 0.9329. The apparatus demonstrated the capability to record meaningful qualitative trend data of simple harmonic motion to support analytical learning processes.
