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%.

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.

<p><strong>Abstract:</strong> This study aims to determine the problem solving abilities of high school students in solving physics problem topic working and energy. A total of 64 respondents solved physics problem about work and energy which consisted of four questions. The students' answers were evaluated using a rubric consisting of five indicators, namely useful description (UD), physics approach (PA), specific application of physics (SPA), mathematical procedures (MP), and logical progression (LP). The data analysis technique used qualitative descriptive. The results of the analysis show that the score of students' problem solving abilities is in a sufficient category, with the dominant score on indicators UD, PA and SPA. Students get poor score criteria on MP and LP indicators. In this case, students experience some difficulties, among others, students' mistakes in applying physics concepts in mathematical equations, students' mistakes in using equations that are not relevant to the problems presented and students' mistakes in using calculations that do not focus on the problem presented.</p><strong>Abstrak:<em> </em></strong>Penelitian ini bertujuan untuk mengetahui kemampuan pemecahan masalah siswa SMA dalam memecahkan persoalan usaha dan energi.

<div class="WordSection1"><p>Argumentation is scientific discourse in science learning that is used as a link between knowledge from an environment and concepts in science learning. Through argumentation skills can be controlled student understanding in connecting facts with concepts in learning. This study aims to analyze students' argumentation ability on buffer solution subject. Students' argumentation ability is divided into 4 levels; level 1 (claims), level 2 (claims with data), level 3 (claims with data and one rebuttal), and level 4 (claims with more than one rebuttal). Data analysis was done by a qualitative descriptive method using a case study method. The case study method was chosen so that a study of 92 students who were research participants could be carried out in depth and comprehensive. The results obtained that the students' argumentation ability was at level 1 and level 2 argumentation. This shows that students' argumentation skills are still at low and medium levels. The results of this study can be used as a basis for improving the quality of teaching and further research.</p><strong><em></em></strong><em></em><em></em></div><em><br clear="all" /> </em>

Creative Thinking Ability

This study aims to determine the ability of creative thinking high school students in physics learning, know the form of assessment of creative thinking abilities. The study was conducted at SMAN 6 Yogyakrata. This type of research is a survey with a cross-sectional method that is a survey conducted once and at a time. The subjects were the principals, teachers of physics from SMAN 6 Yogyakrata and 30 grade XI students. observations, interviews, and questionnaires were used as data collection techniques. The data analysis method used was the quantitative-qualitative descriptive analysis. The results showed that the creative thinking ability of class XI MIA 1 students at SMAN 6 Yogyakarta can be said to be in the average and quite good category, although there are some students whose level of creative thinking ability is low. In addition, the form of assessment used by physics teachers has not been effective and accurate enough in assessing students 'creative thinking abilities. So it is recommended to use The Torrance Tests of Creative Thinking (TTCT) in physics learning because it has been proven to be accurate in assessing students' creative thinking abilities.

Abstract As changes in coastal and marine environments are expected to negatively affect Brazilian ecosystems, the importance of Marine Environmental Education (MEE) comes to the fore. However, so far only 32 contributions related to this issue have been published in Brazil. The MEE workgroup of ReBentos aims at promoting EE and the communication of marine ecological research to the scholastic public as a whole, as well as to groups which exert an influence on general perception, such as the media, politicians, and scientists. This paper presents an overview of the initiatives of MEE in Brazil, with emphasis on the ReBentos projects and guidelines. The conceptual background of action is based on the Rio'92 Treaty on Environmental Education, thereby implying an MEE with Transdisciplinar, emancipatory and reflexive characteristics, directed to changes in values, principles and attitudes. During the period 2011 to 2015, 10 projects were developed from Alagoas to Santa Catarina States, involving the development, implementation and testing through scientific research of 16 MEE activity-models. The didactic material subsequently produced comprised three books and 21 book-chapters. A public of around 6,500 Conservation Unit visitors, 250 public school teachers and 800 high school students have been impacted to date. To act as monitors and multipliers, 250 undergraduate students and professionals were trained. Research project evaluation generated the publication of nine papers. As a further step, the need for protocol elaboration for each model is placed in evidence, in order to direct and facilitate future initiatives.
