Abstract

This study aims to design an alternative instrument for measuring acceleration in linear motion dynamics experiments, named LiTA (Liquid Tilt Accelerometer). The research employed a Research and Development (R&D) method using the ADPT (Analysis, Design, Prototyping, and Testing) approach. The needs analysis stage was conducted using a questionnaire, and the data were analyzed with VOSviewer. The results of the needs analysis revealed that the required experimental instrument should be easily obtainable at an affordable cost, simple in both operation and maintenance, and Integrated technology with digital support is already available. The design of LiTA utilizes the movement of water in a vessel mounted on a dynamics cart. The object’s acceleration is determined based on the inclination of the water surface inside the vessel. The prototyping of LiTA used transparent acrylic with black striped transparent stickers attached as a reference to help measure the air slope in the vessel. The testing process was carried out by conducting experiments to measure the acceleration of an object, and the results were compared with the theoretical acceleration values. The experimental data were analyzed using a paired sample t-test and the Bland–Altman plot method. The results of the paired sample t-test showed a p-value greater than 0.05, specifically 0.079, at a 95% confidence level. This indicates that there is no significant difference between the calculated acceleration and the experimental acceleration, when the pulley’s moment of inertia is included in the acceleration calculation. All data points fall within the limits of agreement when analyzed using the Bland–Altman plot. The LiTA acceleration measurement instrument can serve as an alternative apparatus for experiments on linear motion dynamics. It provides a feasible solution for measuring acceleration in situations where conventional experimental equipment is limited or unavailable.

Abstract

The Instrument for Resonance Accuracy and Misconception Analysis (IRAMA) was developed to identify college students’ sound wave resonance conceptions with Rasch. The Identify, Design, Development, Evaluation (IDDE) was used with 30 participants (9 females and 21 males) from one of the universities in Bandung, and four experts (2 in physics and 2 in education) served as IRAMA validators. Rasch analysis used Minifac 4.4.0 (MF-RM) with the rater reliability of 0.75, Infit-MnSq values of 0.77–1.38, and Outfit-MnSq values are outside the ideal limits on item 5 (3.72) (the rest is ideal).  With Jamovi 2.7.2, we confirmed the presence of bias in one of the raters for item 5. The Ministep 5.10.1, based on conceptual categories, Full Understanding (FU), Partial Plus (PP), Partial Minus (PM), Don't Understand (DU), Misconception (MC), and Not Defined (ND). Meanwhile, identification for confidence is based on Full Confidence (FC), Partial Confidence (PC), Not Confidence (NC), and Not Defined (ND). The Cronbach Alpha reliability for conception (0.84), with the highest being in the PM category (27%), and the lowest is in the DU and ND categories (10%). For confidence, the Cronbach Alpha reliability (0.91), with the highest category is in FC (77%), and the lowest is in the ND category (6%). IRAMA is also free from bias towards gender for conception and confident answers (PROB>5% and meet the threshold DIF Contras). Thus, the IRAMA can be an instrument to identify resonance conceptions and, in the future, will be an tool in resonance Augmented Reality (AR) application.
