Pemahaman konsep merupakan kemampuan yang dimiliki siswa untuk menghubungkan konsep atau fakta sesuai dengan pengetahuan yang dimilikinya. Penelitian ini bertujuan untuk mengetahui partisipasi dan peningkatan pemahaman konsep siswa terhadap materi pesawat sederhana setelah mengikuti pembelajaran dengan menggunakan pendekatan investigasi. Penelitian ini menggunakan desain penelitian One-Group Pretest-Posttest Design. Populasi penelitian adalah seluruh kelas VIII semester 1 SMP Negeri 1 Gunung Purei tahun ajaran 2018/2019. Sampel penelitian sebanyak satu kelas diperoleh dengan menggunakan teknik random sampling, yaitu kelas VIII-A dengan jumlah siswa 24 orang. Pengambilan data menggunakan instrumen berupa: (1) lembar pengamatan partisipasi siswa dan (2) tes uraian pemahaman konsep dengan label konsep. Analisis data menggunakan (1) lembar observasi pengamatan dan (2) menggunakan rumus N-Gain. Hasil penelitian diperoleh skor partisipasi siswa melakukan percobaan dan bertanya kepada guru sebesar 77 dan 86 dengan kategori baik, skor mengemukakan pendapat dan mengkomunikasikan hasil kerja kelompok sebesar 75 dan 72 dengan kategori cukup baik, serta skor merevisi hasil kerja kelompok sebesar 63 dengan kategori kurang. Peningkatan pemahaman siswa Label Konsep Tuas dan Katrol sebesar 36% dengan skor N-Gain 0,36 berada pada kategori sedang dan peningkatan pemahaman siswa Label Konsep Bidang Miring dan Roda Berporos sebesar 38% dengan skor N-Gain 0,38 berada pada kategori sedang.  Dengan demikian, dapat disimpulkan bahwa penggunaan pendekatan investigasi dapat meningkatkan partisipasi siswa dan pemahaman konsep siswa.   Understanding the concept is the ability possessed by students to connect concepts or facts in accordance with the knowledge they have. This study aims to find out improvement of students’ participation and conceptual understanding in simple machine material after following learning using an investigative approach. This study uses the One-Group Pretest-Posttest Design research design. The study population was all class VIII 1st semester of Gunung Purei 1 Junior High School 2018/2019. One class of research sample was obtained using random sampling technique, namely class VIII-A with 24 students. Data retrieval uses instruments in the form of: (1) student participation observation sheet and (2) test description of concept understanding with concept label. Data analysis used (1) observation observation sheet and (2) using N-Gain formula. The results obtained scores of student participation in conducting experiments at 77 with good categories, scores expressing opinions or ideas amounting to 75 with fairly good categories, scores asking questions to teachers amounting to 86 with good categories, scores communicating group work results of 72 with a fairly good category, and the score revising group work results by 63 with less categories. Increasing students' understanding of the Lever and Pulley Concept Label by 36% with the N-Gain score of 0.36 in the medium category and increasing student understanding Inclined Plane and Wheel and Axle Concept Labels were 38% with the N-Gain score of 0.38 in the medium category. Thus, it can be concluded that the use of an investigative approach can increase student participation and understanding students' concepts

Diagrammatic presentations of verbal materials might be superior to tables because they emphasize contiguity among the items to be learned. In this study, diagrams were superior learning devices, although Ss preferred tables. As in prose research, a horizontal arrangement of the associates was superior but only if the concept label was left-most. The important factor seems to be whether dominant oculomotor habits correspond to the conceptual processing strategy employed by Ss.
