Abstract

This study aims to present ways of implementing inquiry- learning model with the use of scientific reports to improve teachers’ understanding and ability on teaching biology at secondary level. The quantitative research method is quasi-experiment design with pre-test and post-test control group. The research instrument for collecting data of students’ higher order thinking skills is scoring rubrics for assessing abilities on developing and presenting a scientific report. The instruments for assessing teachers’ skills are teacher observation sheets over inquiry-based learning scientific report using an induction method. The research subjects consist of 4 biology teachers and 80 of grade 10 students from Public Secondary School 3 Samarinda.The teachers are all female; while from 80 students, 53 of them are female and the rest 27 are male. The students’ age ranges from 16 to 18 years old. The research lasted for 1 month.Analysis of data uses t test, that if t_outcome is higher than t_table, the inquiry-based learning model using scientific reports does affect students’ higher order thinking skills. Data analysis is composed in tabulation format with several graded categories: inadequate, sufficient, good and excellent. The result of the study is that higher order thinking skills of students are increasing in numbers and more equal compared with classes taught by teachers who did not follow the inquiry-based learning model workshop and presentation. The inquiry-based learning model was applied via preparation and presentations of scientific reports after the students carry out practical activities through the guidance of student activity worksheets.
