Feasibility of Structured Assignment Sheets to Train Argumentation Skills on Buffer Solutions

Lembar penugasan terstruktur keterampilan argumentasi (LPT-KA) bertujuan untuk melatihkan keterampilan argumentasi peserta didik pada materi larutan penyangga. LPT-KA disusun menggunakan Toulmin’s Argumentation Pattern (TAP) yang terdiri dari enam indikator keterampilan argumentasi, yakni: (1) claim, (2) evidence, (3) warrant, (4) backing, (5) qualifier, dan (6) rebuttal. Penelitian ini bertujuan untuk mendapatkan data kelayakan yang ditinjau dari (1) validitas, (2) kepraktisan, dan (3) keefektifan. Penelitian pengembangan LPT-KA menggunakan model pengembangan ADDIE. Data hasil penelitian diperoleh dari: (1) validasi yang ditinjau dari validitas isi dan validitas konstruk, (2) kepraktisan yang ditinjau dari angket respons peserta didik, dan (3) keefektifan yang ditinjau dari peningkatan hasil post-test dan pre-test yang diketahui dari hasil uji one sample t-test dan uji kecocokan Chi Square. Hasil penelitian menunjukkan bahwa validitas LPT-KA ditinjau dari validitas isi dan validitas konstruk mendapatkan kriteria sangat valid dengan skor modus 5. Angket respons peserta didik memperoleh peRsentase 95%, sehingga LPT-KA dinyatakan sangat praktis. Keefektifan LPT-KA yang ditinjau dari peningkatan hasil post-test dan pre-test memperoleh nilai nilai t_hitung  t_tabel, dengan t_hitung sebesar 34.22 pada uji one sample t-test yang berarti terjadi peningkatan hasil post-test dan dibandingkan rata-rata pre-test. Hasil uji kecocokan Chi Square memperoleh nilai _{hitung tabel}, dengan _hitung sebesar 11.960yang berarti terdapat kecocokan antara level argumentasi post-test dengan level argumentasi LPT-KA. Berdasarkan hasil validitas, kepraktisan, dan keefektifan yang diperoleh, LPT-KA dinyatakan layak digunakan dan dapat melatihkan keterampilan argumentasi peserta didik pada materi larutan penyangga.

The structured argumentation skills assignment sheet (LPT-KA) aims to train students' argumentation skills on buffer solution material. LPT-KA is structured using Toulmin's Argumentation Pattern (TAP) which consists of six indicators of argumentation skills, namely: (1) claims, (2) evidence, (3) warrants, (4) backing, (5) qualifiers, and (6) rebuttal. This research aims to obtain data feasibility in terms of (1) validity, (2) practicality, and (3) effectiveness.LPT-KA development research uses the ADDIE development model. The research data were obtained from: (1) validation in terms of content validity and construct validity, (2) practicality in terms of student response questionnaires, and (3) effectiveness in terms of the increase in post-test and pre-test results which are known from the results of the one sample t-test and the Chi Square fit test. The results showed that the validity of the LPT-KA in terms of content validity and construct validity obtained very valid criteria with a mode score of 5. Student response questionnaires obtained a percentage of 95%, so that LPT-KA was stated to be very practical. The effectiveness of LPT-KA in terms of the increase in post-test and pre-test results obtained a value t_{count table},, with a  t_count,  of 34.22 on the one sample t-test which means there was an increase in post-test results compared to the pre-test average. The results of the Chi Square fit test obtained the value _{count table}, with _count of 11,690 which means there is a match between the post-test argumentation level and the LPT-KA argumentation level. Based on the results of validity, practicality, and effectiveness obtained, LPT-KA was declared feasible to use and could train students' argumentation skills on supporting materials.
