Abstract

Natural selection is one of the topics of evolution material that is considered difficult for students, so it is necessary to have a practicum to help in understanding this material. Limited laboratory equipment in schools is an obstacle to learning evolution, so learning media are needed to support evolution learning. One of the learning media that can be applied is PhET simulation. PhET simulation supports evolution learning because it provides simulations in the form of processes of how living things experience natural selection mechanisms. This service program aims to describe students' cognitive understanding of the topic of natural selection with the help of the PhET simulation application. This activity is expected to be used as reference material for teachers who conduct practicums with the help of the PhET simulation application. The subjects who participated in this service activity were 30 students in class XII MIPA. The service activities were carried out on June 16–23, 2023, at SMAN 4 Tuban. The service activities carried out include training, discussion, and guidance. Based on the results of the program, it can be seen that the trainees were very enthusiastic about participating in the PhET simulation activities, the use of PhET simulation was easy to apply, and the trainees were easier to understand the material with the help of this application (87% of the time).

Abstract

The utilization of local potential in the campus area has not been done optimally. The need for contextualized learning resources requires lecturers to provide appropriate learning resources for students, including biology education students in plant morphology. This study aims to utilize the local potential of the campus area as a learning resource regarding the diversity of Poaceae based on morphological reviews. The type of research used is descriptive quantitative. The data collection method in this study was observation. Sampling technique by making plots with the quadrat method with a size of 1x1 meter at several points in the campus area. The results of this study indicate that the Poaceae family identified in the PGRI Ronggolawe University campus area consists of 12 species, including Stenotaphrum secundatum, Elymus repens, Poa annua, Paspalum dilatatum, Chloris barbata, Zoysia japonica, Muhlenbergia schreberi, Thyrsotachys oliveri, Bambusa vulgaris, Cymbopogon citratus, Digitaria sanguinalis, Panicum repens with four subfamilies namely Bambusoideae, Pooideae, Panicoideae, Chloridoideae with a total of 259 individuals found. Overall, the level of Poaceae diversity in the campus area is H’ = 2.19, which is a moderate category. The level of Poaceae diversity in the campus area from the highest to the lowest value is the subfamily Panicoideae (1.09), Chloridoideae (1.05), Pooideae (0.69), and Bambusoideae (0.66). Analysis of the potential of the research results shows that the diversity of Poaceae in the campus area can be used as learning material for plant morphology for biology education students.

Abstract

The development of technology is currently accelerating. One of the uses of technology in education is teaching or supporting media in learning. This study aimed to design E-instructions for the stomata observation practicum inquiry method to improve critical thinking in learning valid plant anatomy and to determine E-instructions' validity to improve critical thinking in learning plant anatomy. The method in this research is the ADDIE method, which has several stages: analysis, design, development, implementation, and evaluation. This research data was collected using validity instruments in the form of validity sheets. This research uses a descriptive quantitative data analysis technique describing the data's validity. The validity test results get the following average: the material aspect receives an average of 85.8%, the systematic aspect gets a validity value of 84.3%, the language aspect gets a value of 88.3%, and the graphic aspect receives a value of 89.3%. The average score for all aspects of the assessment is 86.9%. Based on the scores of the three expert validators, it can be concluded that the results of the validation of the Inquiry-Approach Practicum E-Instructions to Improve Critical Thinking in Plant Anatomy Learning are in the very valid category.
