This research was conducted to determine the level of validity and student response of LKPD teaching materials based on the SSCS model to foster students critical thinking skills. The development model used by the 4-D model has the stages define, design, develop, dessiminate. The method used is the Research and Development (R&D) method. The instruments used were interview questionnaires, student response questionnaires, and validation questionnaires. Analyze the data descriptively and qualitatively. The percentage results of validating LKPD teaching materials obtained from material expert validators were 90,20% (very valid), teaching material expert validators 87,70% (very valid), practitioner expert validators 90,97% (very valid). The result of the student response level show a percentage value with an averge of 86,07% (very valid). With this, it can be concluded that the LKPD based on the SSCS model of mixed separation material can be used by students in the science learning process. date: 2025-07-31 type: Thesis type: NonPeerReviewed format: text language: id identifier: https://eprints.untirta.ac.id/53271/1/TITI%20DEWI%20ANGGRAENI_2281200066_FULLTEXT.pdf format: text language: id identifier: https://eprints.untirta.ac.id/53271/2/TITI%20DEWI%20ANGGRAENI_2281200066_CP.pdf format: text language: id identifier: https://eprints.untirta.ac.id/53271/12/TITI%20DEWI%20ANGGRAENI_2281200066_01.pdf format: text language: id identifier: https://eprints.untirta.ac.id/53271/13/TITI%20DEWI%20ANGGRAENI_2281200066_02.pdf format: text language: id identifier: https://eprints.untirta.ac.id/53271/14/TITI%20DEWI%20ANGGRAENI_2281200066_03.pdf format: text language: id identifier: https://eprints.untirta.ac.id/53271/18/TITI%20DEWI%20ANGGRAENI_2281200066_04.pdf format: text language: id identifier: https://eprints.untirta.ac.id/53271/19/TITI%20DEWI%20ANGGRAENI_2281200066_05.pdf format: text language: id identifier: https://eprints.untirta.ac.id/53271/20/TITI%20DEWI%20ANGGRAENI_2281200066_REF.pdf format: text language: id identifier: https://eprints.untirta.ac.id/53271/21/TTI%20DEWI%20ANGGRAENI_2281200066_LAMP.pdf identifier: ANGGRAENI, TITI DEWI (2025) PENGEMBANGAN LKPD BERBASIS MODEL SSCS (SEARCH, SOLVE, CREATE, AND SHARE) MATERI PEMISAHAN CAMPURAN UNTUK MENUMBUHKAN KETERAMPILAN BERPIKIR KRITIS SISWA KELAS VIII SMP.
