Arguing from evidence is one of eight key science practices in which students should engage. It is an essential component of science, yet students have difficulties with this practice. We describe a scaffolded claims-evidence-reasoning (CER) argumentation framework that is embedded within a new eight-week, freely available curriculum unit developed by the Genetic Science Learning Center – Evolution: DNA and the Unity of Life. The scaffold provides high school students with practice in both developing and evaluating written arguments. It is designed to incrementally build student skill week-by-week, starting with an introduction to the CER components of an argument, and ending with students evaluating data and constructing a supported written argument. We also present evaluation findings from field testing the argumentation scaffold in the context of the complete Evolution unit in dozens of classrooms. And we discuss how this integrated, scaffolded approach to argumentation influenced both student and teacher learning.

This study aims to determine the morphometry of Sumatran turtles in the conservation area of the Turtle Learning Center (TLC), Bengkulu University and the Ruyani Life Science Learning Resource (SBIH), then the results of this morphometric study are made into E-Module products. This type of study is a Research and Development (R&D). Data collection techniques were performed in the form of observation and documentation. The data analysis technique used a qualitative descriptive technique, namely the data obtained and then analyzed descriptively. Morphometric data were analyzed using qualitative descriptive. Furthermore, the product is made in the form of an E-Module. Research results of Morphometric studies in TLC contained five types of Sumatran turtles, namely Cuora amboinensis, Heosemys spinosa, Cyclemys dentata, Siebenrockiella crassicollis, and Manouria emys. In SBIH Ruyani, there are four types of Sumatran turtles, namely Dogania subplana, Pelochelys cantorii and Orlitia borneensis. The results of the E-Module product for the morphometric study of the Sumatran turtles after validated by the expert obtained a very decent assessment presentation. The material expert validator obtained an assessment presentation of 86.53%, and the media expert obtained an assessment percentage of 91.67%.

Various types of educational devices that are used as a support for the creation of a good education are certainly important. One of them is using an effective method to provide a concept to students optimally. This study aims to analyze how high and important the influence of the experimental method on science subjects at the junior high school. The method used is a qualitative research method with a mini survey method on 47 samples consisting of junior high school students, high school students, college students, and alumni students as well as a literature study method (library study) which is carried out by screening electronic books (e-books) and e- journals. The results showed that 94% of experimental research methods were effectively used and 6% were not effectively used in the science learning process. The effectiveness of this method is that students can prove that an accepted concept is in accordance with the given theory and students can hone their psychomotor abilities. The weakness of this method is that it can be seen from the inadequate infrastructure, the ability of teachers, controlling students, and the selection of practicum materials.

Technical Assessment

During the Cultivating Diverse Talent in STEM (CDTIS) Project, a team of scientists, teachers, and a researcher developed a performance-based assessment of high school students’ creative problem-solving skills and ability to apply physical science principles in practical ways. It was one of six measures to identify exceptionally talented students. Students identified using conventional methods (M1), with an average grade point average (GPA) of 3.93, had an average rating of 2.95 on a 5-point scale on the mechanical–technical assessment. The M2 students, who were from schools with high percentages of Hispanic, American Indian, and low socioeconomic status (SES) students, had an average GPA of 3.07 and an average rating of 3.27, demonstrating that this assessment can be an important way to change the cultural and economic balance of students identified as exceptionally talented in Science, Technology, Engineering, and Mathematics (STEM). Other researchers are encouraged to examine the validity of the mechanical–technical assessment to identify exceptionally talented students in different groups.
