Kelayakan LKPD Berorientasi Assessment For Learning untuk Meningkatkan Hasil Belajar Peserta Didik pada Materi Titrasi Asam Basa

Feasibility of Student Worksheet Oriented on Assessment For Learning to Improve Learning Outcomes on Acid Base Titration Material

LKPD berorientasi assessment for learning bertujuan untuk meningkatkan hasil belajar peserta didik pada materi titrasi asam basa. LKPD ini disusun dengan mengikuti sintaks inkuiri terbimbing yang berorientasi pada assessment for learning. Penelitian pengembangan LKPD ini menggunakan metode Research and Development (R&D) dengan menggunakan model pengembangan Borg and Gall. Data hasil penelitian diperoleh dari: (1) validitas yang ditinjau kriteria isi, konstruk dan penyajian yang diukur dengan lembar validasi dan dihitung modus pada tiap aspek, (2) kepraktisan yang ditinjau dari hasil angket respon peserta didik dan ditunjang lembar observasi aktivitas peserta didik, dan (3) keefektifan yang ditinjau dari peningkatan hasil belajar peserta didik yang diketahui dari hasil uji one sample t-test dan uji kecocokan Chi Square. Hasil penelitian menunjukkan bahwa validitas LKPD yang ditinjau dari kriteria isi, konstruk dan penyajian dikatakan valid dan sangat valid dengan skor modus berturut-turut 4; 4; dan 5. Kepraktisan LKPD yang ditinjau dari angket respon peserta didik memperoleh persentase sebesar 96,29% dan ditunjang dengan aktivitas relevan peserta didik pada pertemuan 1 dan pertemuan 2 berturut-turut sebesar 84,44% dan 88,89% sehingga LKPD dinyatakan sangat praktis. Keefektifan LKPD yang ditinjau dari peningkatan hasil belajar peserta didik yang memperoleh nilai t_hitung  t_tabel pada uji one sample t-test dengan nilai berturut-turut sebesar 16,936 dan 11,246 yang berarti terdapat perbedaan signifikan sebelum dan sesudah diterapkan LKPD, serta terdapat kecocokan antara assessment for learning dan hasil belajar yang memperoleh nilai Chi_hitung  Chi_tabel berturut-turut sebesar 11,455 dan 12,915 sehingga LKPD dinyatakan efektif. Berdasarkan hasil validitas, kepraktisan dan keefektifan yang diperoleh, maka LKPD berorientasi assessment for learning dinyatakan layak digunakan dan dapat meningkatkan hasil belajar peserta didik pada materi titrasi asam basa.

Student Worksheet oriented on assessment for learning aims to improve the learning outcomes of students on acid-base titration material. This LKPD is prepared by following the syntax of guided inquiry oriented towards assessment for learning. This student worksheet development research uses the Research and Development (R&D) method using the Borg and Gall development model. The research data were obtained from: (1) validity reviewed by criteria of content, construct and presentation measured by validation sheets and calculated mode in each aspect, (2) practicality reviewed from the results of student response questionnaires and supported by student activity observation sheets, and (3) effectiveness in terms of improving student learning outcomes known from the results of the one sample t-test and the Chi Square test. The results showed that the validity of student worksheet in terms of the criteria of content, construct and presentation was said to be valid and very valid with a consecutive mode score of 4; 4; and 5. The practicality of student worksheet in terms of student response questionnaires obtained a percentage of 96.29% and was supported by relevant activities of students at meeting 1 and meeting 2 respectively of 84.44% and 88.89% so that student worksheet was declared very practical. The effectiveness of student worksheet in terms of the improvement in learning outcomes of students who obtained t_calculated ≥ t_tabel scores on the one sample t-test with consecutive values of 16.936 and 11.246 which means that there are significant differences before and after the implementation of student worksheet, and there is a match between assessment for learning and learning outcomes that obtain Chi_calculated ≥ Chi_table scores of 11,455 and 12,915 respectively, so that student worksheet was declared effective. Based on the results of validity, practicality and effectiveness obtained, the student worksheet oriented on assessment for learning is declared feasible for use and can improve student learning outcomes on acid-base titration material.
