Enhancing Biotechnology Education through BioVate Competition: Increasing Conceptual Understanding and Science Communication in Science Education

2025-03-20T15:47:58+00:00

The goal of this study was to explore the effectiveness of implementing competition during a learning process to elevate motivation and science communication skills in a particular biotechnology education course among the third-year science education students at Universitas Sultan Ageng Tirtayasa using the BioVate competition, in which incorporates project-based learning (PjBL) within competitions during learning process. It is a unique model for competitive learning. A quasi-experimental model was employed on a sample comprising 67 undergraduate students. Students had no prior biotechnology training and the intervention lasted four weeks. It comprised problem identification and solving, solution development, as well as a culmination competition. In the assessment, significant changes with respect to motivation (mean 2.7 to 4.1, d 0.54) and comprehension (mean 8.7 to 18 out of 20, d 0.92) were noted in pretest-posttest analysis. In the observation, interview and document analysis, participants noted improvement with respect to good communication, articulation of complex ideas, increased self-confidence, and effective use of visual aids. The major premise of the BioVate model, the ability to tackle real problems (for example, the use of CRISPR technology for developing pest-resistant crops), was reported to have fostered intrinsic motivation and closed the theoretical-practical gap. These findings also support constructivist learning theory and self-determination theory by highlighting the impact of competition and collaboration on engagement. This new approach contributes to increasing comprehensive conceptual understanding in biotechnology and builds skills in future educators and science communicators to address societal issues with an interdisciplinary approach.

Linier Perturbation Method Analytic Shear Wave Propagation In A Dispersive Medium

2025-01-26T07:38:46+00:00

This research was based on showing how the relationship of the perturbation method to the wave function entering the dispersive medium area. Disperse medium is a medium where when the wave enters the area, it experiences changes in wave shape and wave energy. The purpose of this study is to show how the perturbation method can be reduced to a term that is still linear with the assumption that the next term is very small so that the wave term is still linear to the wave change. This research is qualitative research. The place of this research is at the TD Pardede Institute of Science and Technology. From the analysis in this study, it was found that the wave experienced a decreasing intensity towards the depth of the dispersive medium with the assumption that the attenuation coefficient ( ) was still continuous along the depth of the material passed by the wave. In the case of seismic waves when the wave moves through the medium, its intensity decreases with distance. The presence of disturbances in the layer passed by the wave causes the shift of the material to experience a disturbance characteristic where the wave amplitude is getting smaller. This is because the absorption of wave energy by the particles of the dispersive medium continues to experience attenuation.
