Abstract
This study aims to determine the effect of Group Investigation with Project Based Learning model towards higher order thinking. The population of this research were the total, 60 under-graduated students of Simalungun University in fourth semester. They grouped as first experimental class treated by Group Investigation combine with PJBL, for next experimental class taught by Group Investigation and for control class taught by using conventional learning model. The research instrument uses a test result of learning ability of higher order thinking. This study include quasi experimental method. The data were analyzed by helping SPSS 21.0 program using F-test (ANACOVA α = 5% ). The results shown that: The higher order thinking ability of under-graduated students of Simalungun University treated by Group Investigation were significantly high (88,60 ± 3,73; x̄ ± SD) than group investigation class (81,00 ± 4,01 (x̄ ± SD) and conventional class 74,60 ± 3,58 (x̄ ± SD) with (Fhitung=67,742; P=0,000). Therefore, it can be concluded that Group Investigation combine with PJBL were affected the students’ higher order thinking abilities

Summary
Penelitian ini dilaksanakan di Program Studi Pendidikan Biologi FKIP Universitas Simalungun, Jalan Sisingamangaraja Barat 1, Bah Kapul, Kecamatan Siantar Martoba, Pematangsiantar pada bulan Desember 2014 sampai Maret 2015. Instrumen pengumpulan data terdiri dari alat tes tertulis untuk mengetahui tingkat keberhasilan belajar ekologi hewan yang dalam hal ini dibatasi pada berpikir tingkat tinggi mahasiswa. Tes hasil belajar mahasiswa yang digunakan untuk mengukur hasil belajar kognitif siswa terlebih dahulu diujicobakan untuk mengetahui validitas, reliabilitas, daya beda dan tingkat kesukarannya. Pengujian validitas dan reliabilitas instrumen tes hasil belajar mahasiswa dilakukan dengan bantuan program komputer Mikrosoft Excel. Begitu juga untuk uji daya beda dan tingkat kesukaran tes dilakukan dengan bantuan program komputer Mikrosoft Excel. Analisis statistik inferensial dilakukan untuk menguji hipotesis penelitian, yang terlebih dahulu dilakukan uji prasyarat terhadap data yang dikumpulkan dengan menggunakan uji normalitas dan homogenitas. Teknik analisis data inferensial digunakan untuk menguji hipotesis penelitian dengan menggunakan uji FANAKOVA pada taraf signifikan α = 5% kemudian dilanjut dengan Post-Hoc Test (uji lanjut) dengan teknik Tukey.
