Pengembangan LKS Biologi SMA Berbasis Praktikum dengan Model Pembelajaran Langsung untuk Meningkatkan Keterampilan Proses Sains Siswa

Abstract

[Title: Development of Student Worksheets based on Practicum with Direct Learning Models to Improve Students' Science Process Skills]. This research aims to develop student worksheets based on practicum with direct learning models that valid, practical and effective to improve students' science process skills. This research is a development study using 4D stages with the subject of 30 students of class X1 IPA1 MAPK Syeh Zainuddin Anjani. The developed student worksheet was validated by three competent validators using validation sheets. The practicalities of the worksheets developed were measured using student response questionnaires, while the effectiveness of worksheets was measured using an observation sheet of students' science process skills by two observers. Research data were analyzed descriptively and quantitatively. The results showed that the student worksheets with tissue culture material were quite valid (a score of 3.9), the students' responses after learning showed a high percentage with a very strong category (81%-100%), while the students' process skills improved at each meeting in the good category. Based on the results of the study, it can be concluded that the student worksheets based on practicum with direct learning models were valid, practical, and effective to improve the students science process skills of MAPK Syeh Zainuddin Anjani.

Exploring pre-service teacher’ views of science process skills

“…The response of pre-service teachers shows that initial knowledge about SPS is not yet comprehensive. These findings reinforce the statement that pre-service teachers SPS are in the low and moderate categories [20,23]which has implications for the low level of pre-service teachers' critical thinking, critical analysis skills [28], scientific attitudes [22], designing experiment in physics learning that need physics factual and conceptual knowledge [42].…”

“…Science learning in Indonesia are more oriented towards memorizing sciences' concepts and facts [19] and does not accommodate the demands of students' SPS development [20,21]. Such condition is thought to be the reason for students' low SPS [20,22]. The pre-service teachers' SPS is generally in moderate category, with hypothesis and defining variables operationally indicators as the lowest score [23].…”

Pickles: Independent Biology Practicum Diffusion and Material Osmosis On the Concept of Substance Transport during the Pandemic Period

“…Meanwhile, depending on the findings of the study carried out (Khaerunnisa, Kusmiyati, & Ilhamdi, 2019) known that the difficulties experienced by students in practicum are skills, readiness, psychological-emotional habits, attitudes, physical conditions, interest in practicum, the accuracy of concentration, knowledge of practicum material and student motivation. The success of a practicum was determined by the practicum worksheets that are developed; this is in line with (Mirawati & Royani, 2019) Practicum-based high school biology LKS on tissue culture material developed valid, realistic, and successful to enhance the scientific process of MAPK students Syeh Zainuddin Anjani.…”

Analisis Komponen Penyusun Desain Kegiatan Laboratorium Berbasis Keterampilan Proses Sains Pada Materi Kerja Enzim Katalase

“…Keterampilan proses sains adalah suatu keterampilan seseorang dalam menggunakan pikiran, nalar dan perbuatan secara efektif dan efisien untuk mencapai suatu hasil tertentu (Elvanisi et al, 2018). Keterampilan dasar dalam keterampilan proses sains meliputi : 1) mengamati, 2) menyusun hipotesis, 3) merumuskan masalah, 4) mengidentifikasi variabel, 5) mengkomunikasikan data dan 6) menyimpulkan data (Mirawati & Royani, 2019). Penelitian Elvanisi et al,(2018) mengatakan bahwa persentase keterampilan proses sains yang dikuasai oleh siswa SMA se-Kecamatan Bukit Kecil Palembang yaitu indikator tertinggi meramalkan sebesar 73,48% dan indikator terendah merumuskan hipotesis 42,04%.…”
