The 3D Printing in Material Research and Medical Physics Education and Its Accuracy Study
Get PDFThis study aims to construct prototypes using three-dimensional (3D) printing technology as a research apparatus and a physics education instrument, particularly in medical physics education. Two main designs of prototypes have been arranged. Two foam NaCl templates are drawn using computer-aided design (CAD) software. Image processing techniques achieve a 3D model of a thoracic vertebra. All 3D model data are printed using polylactic acid (PLA) filament. The prints of foam NaCl templates are utilized for holding the NaCl powder. The prototype of a human vertebra is used for visualization of the real condition of the human bone anatomy. The results of the prototypes are analyzed to investigate the similarity between the model and the prints. This investigation is done using a Vernier Caliper and CT Scan. The measurement using Caliper shows a higher percentage in likeness than the CT-Scan. All the accuracy study shows they have more than 83% in similarity. It can be concluded that all built prototypes have prominent exactitude and can support the material research using the printed NaCl templates. Hereafter, a bone mock-up’s genuine perception can function for further application, such as implant or surgery planning
The Impact of the E-Learning Module on Remediation of Misconceptions in Modern Physics Courses
Get PDFThe misconception in mastering physics concepts occurs in basic physics and is also found in advanced physics, such as Modern Physics or Quantum Physics. Efforts to remediate misconceptions have been done manually or offline but are often constrained at too long an interval between identification activities and remediation actions. Through the advancement of online learning systems, E-learning media, these obstacles can easily be overcome. This article will discuss one way of remediation using Moodle-based E-Learning modules. A total of 2 classes (45 students) were randomly selected for the experimental group and two classes (64 students) for the control group. The experimental group used a representative module based on E-Learning as a remediation treatment, while the control group used a conventional module. The results of the validation of the material and the design of the E-Learning modules were obtained as very feasible to use. Data collection uses a two-tier Modern Physic Diagnostic Test or MPDT (Modern Physic Diagnostic Test) of 30 items combined with the CRI (Certainty of Response Index) index. It is carried out twice, namely before and after treatment. The N-Gain normality analysis results showed the percentage of misconception reduction was more significant in the experimental group than in the control group. Important note obtained by implementing E-Learning is more appropriate to be used simultaneously between conventional face-to-face and E-Learning

The Design of One-Dimensional Motion and Two-Dimensional Motion Learning Media Using Digital Camera and Tracker-Based Air Track
Get PDFThis research describes the results of the development of 2D air track tools designed for one and two-dimensional motion experiments with small frictional forces. Friction is minimized by using wind gusts through small holes made in all parts of the runway. Motion detection devices used are digital cameras and trackers. Digital cameras are used to record the motion of objects on a platform in the form of video with a specific frame-rate. Tracker is used to analyzing videos that contain information about object motion. This tool has been tested on one-dimensional motion, that is, an object that slides over an inclined plane and two-dimensional motion in the case of a collision of two objects. In the case of one-dimensional position graphs against time can be displayed, the instantaneous velocity and average and acceleration can be accurately determined. In the case of the collision of two objects, the position graph against time can also be displayed for each object before and after the collision. The velocity vector can be determined accurately so that the law of conservation of momentum and kinetic energy can be verified. One and two-dimensional motion are the concepts that underlie almost all other concepts in physics. Therefore one and two-dimensional motion experiments are important to build students’ experiences of the concept. Thus 2D air track platform based on digital cameras and Tracker software can be used as a physics learning media on motion kinematics materials that can display various kinematics graphs so that information about motion is complete

The Correlation of Isomorphic, Open-Ended, and Conventional Score on the Ability to Solve Kinematics Graph Questions
No full textisomorphic and conventional to open-ended can reflect students' learning difficulties on kinematic's graphs. This study used a quantitative descriptive form of survey research. The respondents were twenty-nine senior high school students from Semarang. The instruments were adopted from the Test of Understanding Graphs-Kinematic (TUG-K) by Robert J.Beichner (1994). There were nine questions used from the TUG-K with open-ended questions that have been validated. The results show that students have difficulties learning about kinematic's graphs, and there is no relation between open-ended scores and the other two scores. Nonetheless, judging from the correlation coefficient, the correlation between open-ended and conventional tasks is 0.075, which means low correlation, while for isomorphic score and open-ended score in the amount of 0.109 is higher than the correlation of traditional and open-ended. This correlation is insignificant. However, the closest correlation direction to the open-ended test is isomorphic compared to the conventional one. Therefore, it is concluded that isomorphic assessment is more useful than traditional review in kinematic graphics
