One of the factors that influence students' learning competence is self-efficacy. The purpose of this study was to determine the relationship between self-efficacy and Biology learning competence of students in class XI MIPA SMAN 1 Hiliran Gumanti. The method used is descriptive correlation using the Spearman rank formula. The results showed that there was a correlation between self-efficacy and Biology learning competence of students with a value of r=0.477 and tcount which was 3.4321 which was greater than t table, which was 2.0218. So, it can be concluded that there is a significant and positive relationship between self-efficacy and Biology learning competence of students in class XI MIPA SMAN 1 Hiliran Gumanti.

However, there is still limited data about preservice teachers’ perception about it. Therefore, the aim of this study is to describe teachers’ perception about Science, Technology, Engineering and Mathematics (STEM) education. This study is a descriptive research using survey method. The data were collected through questionnaire. The collected data was analyzed by using percentage technique. The result shows that there is positive perception among the preservice teachers about STEM education and they are agree of implementing it to educational curriculum in Indonesia.

Learning activities of laboratory knowledge course at this time in the Biology Department, Universitas Negeri Padang has not been completed by supporting learning media such as student lab worksheet. Guided inquiry learning model is one of the learning models that can be integrated into laboratory activity. The study aimed to produce student lab worksheet based on guided inquiry for laboratory knowledge course and to determine the validity of lab worksheet. The research was conducted using research and developmet (R&D) model. The instruments used in data collection in this research were questionnaire for student needed analysis and questionnaire to measure the student lab worksheet validity. The data obtained was quantitative from several validators. The validators consist of three lecturers. The percentage of a student lab worksheet validity was 94.18 which can be categorized was very good.

The benefit of STEM Literacy is that it makes students more skilled in all areas including science, technology, mathematics, and engineering. In ad- dition, STEM literacy can also make students improve their critical thinking skills and become crea- tive, logical, innovative, productive and relate directly to real conditions. This study aims to analyze the needs of students' STEM literacy achievement assessment in learning biology. The type of research used is descriptive, with data collection techniques carried out by conducting observations and inter- views. The results showed that biology learning has been implemented based on STEM literacy, stu- dents are still less enthusiastic in reading, students are more interested in learning related to technol- ogy, teachers do not know the assessment of students' STEM literacy achieveme...

So this research aims to determine the impact of a realistic approach to mathematics education on students' critical thinking abilities. This research is a quasi experimental study with the type of non-equivalent control group design. The research subjects were 29 elementary school students. The results showed t-hitung=6.52 and t-tabel = 1.69092 where t_hitung is greater than the ttabel so that there is a positive influence of the use of Realistic Mathematics Education on the thinking skills of elementary school students, especially in mathematics learning Abstrak: Rendahnya kemampuan siswa dalam menyelesaikan masalah matematika menggambarkan rendahnya kemampuan berpikir kritis siswa. Maka penelitian ini bertujuan untuk mengetahui pengaruh pendekatan realistik pendidikan matematika terhadap kemampuan berpikir kritis siswa. Penelitian ini merupakan penelitian eksperimental semu dengan jenis desain non-equivalent control group. Subjek penelitian adalah 29 siswa Sekolah Dasar. Hasil penelitian menunjukkan t hitung = 6,52 dan t tabel = 1,69092 dimana t hitung lebih besar dari pada t tabel sehingga ada pengaruh positif penggunaan Pendidikan Matematika Realistik terhadap keterampilan berpikir siswa sekolah dasar, khususnya dalam pembelajaran matematika

Not only can it affect the curriculum being taught, but it will also lead to the changes of the methods and approaches in conducting the lesson. One of the changes is the use of digital learning. Universitas Negeri Padang has regulation of conducting lesson through e-learning platform proportionally for all courses, including the course of Ordinary Differential Equation. Ordinary Differential Equation is a mandatory course that should be taken by mathematics department’s students. In order to support students to develop their under standing about the concept and its application while using digital learning method, the researchers develop some tutorial video as supplementary media. Therefore, this study aimed to describe the practicality of the tutorial video. This is a descriptive research where the data were collected using closed q...

STEM in education has the aim of preparing students to be competitive and ready to work according to their preferred fields. The benefits of applying STEM Education are to improve critical thinking skills and be creative, logical, innovative, productive and directly related to real conditions. The purpose of this study is to review the implementation of STEM Education models in the early 21st century. Technique of collecting data was through literature study. The results of this study: 1) STEM has been applied in various countries and in various branches of science; 2) History of STEM Education, 3) Implementation of STEM in non western country, 4) Skill that required in 21 st century, 5) STEM to face 21 st challenge.

The part-whole relation concept is important for students to reason about multiplication of fractions. Realistic Mathematics Education which is in Indonesia adapted as Pendidikan Matematika Realistik Indonesia (PMRI) is used as an approach in designing a series of lessons. For this purpose, hypothetical learning trajectory (HLT) became the base for conducting a teaching experiment and designing its learning materials. The research was conducted in the fifth grade of SD Al Hikmah Surabaya, an elementary school in Indonesia, with five students as the participants. The collected data were qualitative data in the form of students’ written works and the transcript of video recording during the lesson. The data were analyzed retrospectively by confronting the conjecture of students’ thinking in the HLT ...

We might use the SDT point of view to get more insight about motivation in education terminology. Within SDT motivation is classified regarding to its quality and quantity and based on the study by Vansteenkiste et al. (2009) the good quality motivation- high autonomous and low controlled motivation- give a significant influence in improvement of students’ learning outcomes. Therefore, in the classroom of mathematics teachers need support the emergence of the autonomy of the students. Supporting students and improve their motivation towards science especially mathematics, the author believes that there is a correlation between the roles of teacher and students’ motivation. If the teacher designs an adequate teaching and learning activity for the learning process, the students’ interest will increase. Thus, using a good context, which is selected by contextual teaching strategies, can be a go...
