The effectiveness of scientific approach through the website in physics learning process at vocational high school

The purpose of this research is to describe the effectiveness of scientific approach through the website in Physics learning process at Vocational School. The defined scientific processes are: observing, making inquiries, reasoning, trying, and communicating. The type of research is pre-experiment by using a one-shot case study design. The effectiveness is viewed from the scientific processes, conceptual understanding, and students' responses. The subject of this research is 50 students of Multimedia skill program of SMK Negeri 12 Surabaya. The students' concept comprehension scores are obtained from the test, while the measurement of students' scientific process and response use a Likert scale. Data analysis used is a descriptive statistic. The learning process is effective if the student's scientific process and response percentage is ≥ 61% (good or very good), and the student's conceptual understanding average score is x ≥ (70 ± 10). The results obtained are 1) the score of the scientific process is categorized good, 2) students' response is categorized very good, and 3) the average score of students' conceptual understanding x = (76 ± 9). The results showed that the application of the scientific approach through the website is effective to use in physics learning process at vocational high school.
