Abstract

Penelitian ini bertujuan untuk meningkatkan hasil belajar dan kemampuan pemecahan masalah matematis siswa melalui penerapan model Problem Based Learning (PBL) berbantuan pendekatan Teaching at the Right Level (TaRL). Subjek penelitian adalah siswa kelas IX-C SMPN 23 Medan pada semester genap tahun ajaran 2024/2025. Penelitian ini merupakan Penelitian Tindakan Kelas (PTK) yang dilaksanakan dalam dua siklus. Setiap siklus terdiri dari tahap perencanaan, pelaksanaan, observasi, dan refleksi. Data dikumpulkan melalui tes hasil belajar, lembar observasi, dan dokumentasi. Hasil penelitian menunjukkan bahwa terjadi peningkatan signifikan pada hasil belajar siswa. Ketuntasan belajar meningkat dari 26,7% pada pra-siklus menjadi 80% pada siklus II. Rata-rata nilai juga mengalami peningkatan dari kategori rendah menjadi tinggi. Selain itu, kemampuan pemecahan masalah matematis siswa meningkat pada setiap indikator, terutama dalam aspek memahami masalah dan membuat rencana penyelesaian. Penerapan PBL dengan pendekatan TaRL memungkinkan pembelajaran yang lebih kontekstual dan diferensiatif sesuai tingkat kemampuan siswa. Dengan demikian, model pembelajaran ini efektif dalam meningkatkan pemahaman konsep dan keterampilan berpikir kritis siswa dalam menyelesaikan masalah matematis. Rekomendasi dari penelitian ini adalah agar guru menerapkan pembelajaran yang adaptif dan berbasis masalah untuk meningkatkan hasil belajar secara menyeluruh.

Abstract

Thought for a second This study aims to describe the improvement in ninth-grade students’ mathematics learning outcomes at SMP Negeri 23 Medan following the implementation of the Teaching at the Right Level (TaRL) approach. The research employed a classroom action research design, with the subjects being students of class IX-B at SMP Negeri 23 Medan during the second semester of the 2024/2025 academic year. The research instrument used was a series of formative assessments. Data were collected through four phases: planning, action, observation, and reflection. Data analysis was conducted using a descriptive quantitative approach: first, student scores were tabulated and their classical completeness percentages calculated; scores meeting the school’s minimum completeness criterion (KKM) of 75 were considered to have reached mastery. The results showed that in Cycle I, 53.57% of students achieved mastery, which then increased to 82.1% in Cycle II. Since the classical completeness target was met in Cycle II, the research was concluded at that point. Based on these findings, it can be concluded that the use of the TaRL approach in instruction can enhance students’ mathematics learning outcomes.

Abstract

The teachers at SD 173529 are teachers with the status of Civil Servants (PNS). Teachers with the status of civil servants must write scientific papers when going up to a position or class. The problem is writing scientific papers and data processing. The solution offered to overcome this problem is SPSS training include processing research data and how to read the SPSS output to be narrated in the research results. The method used consisted of group discussions, deliberations, in-house training and workshops. The results from this activity are the teacher gives a positive response to the training activities include 100% of teachers liked the training material, the modules used, the way of learning, the way the instructor taught. The other results are the teachers stated that the training material is new (71.42%), the modules used are new (85.71%), the learning method implemented is new (85.71%), the method of teaching is a new way of teaching (85,71%), the teacher expressed interest in using SPSS in processing research data and in training activities (100%).
