Abstract

Most students experience difficulties in understanding mathematical concepts presented by the teacher. This research aims to improve students' conceptual understanding of quadratic functions by implementing a problem-based learning (PBL) model aided by Google Sites. This classroom action research adopts the Kemmis and McTaggart model. The study was conducted in two cycles, with two meetings in each cycle, and the subjects were 36 students of class X-6 at SMA Negeri 1 Sewon. The data collection instruments were learning implementation observation sheets and conceptual understanding test questions. A quantitative descriptive data analysis technique was used with a success criterion of more than 70% of students having a conceptual understanding at least in the high category based on test results. The results showed that the application of the PBL model aided by Google Sites could improve the conceptual understanding abilities of class X-6 students at SMA Negeri 1 Sewon. The greatest improvement in students' mathematical conceptual understanding of quadratic functions between pre-action and cycle I was on the indicator of restating the concept, which was 65.97%. The greatest improvement in students' mathematical conceptual understanding of quadratic functions between cycle I and cycle II was in presenting concepts in various mathematical representation forms, which was 40.28%. In general, the achievement in cycle II was 83.33% of students having a high conceptual understanding ability. This indicates that the student's conceptual understanding in cycle II met the success criteria, which is more than 70% of students having a high conceptual understanding ability.

Abstract

This research explores the effectiveness of problem-based learning (PBL) with Google Sites in improving concept comprehension and reducing math anxiety among 36 class X students at SMA N 1 Sewon. Following Kemmis and Mc Taggart's model, the study consisted of two cycles, each with two meetings. Data collection involved observation sheets, concept tests, and anxiety questionnaires. The success criteria were set at over 70% of students achieving high concept understanding and low anxiety. Results indicate significant improvements in both areas. Between pre-action and cycle I, students' understanding increased by 65.97%, with a further 40.28% increase between cycles I and II. The anxiety decreased by 7.73% and 9.03% between the respective periods. By cycle II, 83.33% of students demonstrated high concept understanding, and 80.56% reported low anxiety, meeting the success criteria. This suggests that PBL with Google Sites effectively enhances concept comprehension and reduces math anxiety among class X students.

Abstract

Tujuan penelitian ini untuk mengetahui besar pengaruh manajemen konflik terhadap kinerja pegawai, dimana penelitian ini menggunakan metode kuantitatif dengan jumlah sampel 45 orang pegawai dengan metode analisis regresi sederhana. Temuan penelitian ini menunjukkan bahwa terdapat pengaruh positif dan signifikan antara manajemen konflik terhadap kinerja pegawai terlihat dari nilai hasil regresi sederhana Y = 7,772+ 0,707X. Berdasarkan pengujian hipotesis menggunakan koefisien determinasi dan Thitung ditemukan bahwa nilai koefisien determinasi sebesar 0.564 yang mengandung arti bahwa pengaruh Manajemen Konflik (X) terhadap Kinerja Pegawai (Y) adalah sebesar 56,4%. Sedangkan berdasarkan Thitung pada taraf signifikan a 0.05 dan df = 45-2 yakni 43, dimana Thitung > Ttabel atau 7.462 > 2.0166 hasil ini juga sekaligus menunjukkan bahwa hipotesis diterima, yaitu ada Pengaruh antara Manajemen Konflik (X) Terhadap Kinerja Pegawai (Y).
