Psychological Treatments and Assessments
Abstract
Student academic success is determined not solely by intellectual capability, but crucially by internal psychological drivers, most notably achievement motivation. Achievement motivation is characterized as an internal psychological determination to attain defined standards of excellence. This study aims to investigate the empirical effectiveness of solution-focused brief group counseling in enhancing achievement motivation among Islamic junior high school students. A true experimental method utilizing a pretest-posttest control group design was applied in this research. The sample comprised 16 students selected via a simple random sampling technique from a identified cohort displaying low achievement motivation, distributed equally into an experimental group (n=8) and a control group (n=8). Data collection employed an achievement motivation Likert scale featuring 35 validated items across favorable and unfavorable statements. The dataset was analyzed using the Shapiro-Wilk normality test, homogeneity test, N-gain calculation, and paired sample t-test via JASP software. The results reveal that solution-focused brief group counseling effectively and significantly increased students' achievement motivation, as evidenced by experimental gain scores substantially outperforming the control group.
ABSTRAK
Keberhasilan proses belajar siswa tidak hanya dipengaruhi oleh kapasitas intelektual semata, melainkan juga didorong oleh faktor psikologis internal seperti motivasi berprestasi. Motivasi berprestasi dimaknai sebagai dorongan internal individu untuk memenuhi kebutuhan diri dalam mencapai standar keunggulan tertentu. Penelitian ini bertujuan untuk menguji keefektifan konseling kelompok singkat berfokus solusi dalam meningkatkan motivasi berprestasi siswa Madrasah Tsanawiyah. Metode yang digunakan adalah eksperimen murni (true experiment) dengan desain pretest-posttest control group design. Sampel penelitian berjumlah 16 siswa yang dipilih melalui teknik simple random sampling dari populasi siswa yang teridentifikasi memiliki motivasi berprestasi rendah, kemudian dibagi secara seimbang ke dalam kelompok eksperimen (n=8) dan kelompok kontrol (n=8). Pengumpulan data menggunakan skala motivasi berprestasi berskala Likert 4 poin sebanyak 35 butir pernyataan valid yang memuat butir favorable dan unfavorable. Analisis data kuantitatif menggunakan uji normalitas Shapiro-Wilk, uji homogenitas, uji N-gain, serta uji beda paired sample t-test berbantuan program JASP. Hasil penelitian membuktikan bahwa konseling kelompok singkat berfokus solusi efektif meningkatkan motivasi berprestasi siswa secara signifikan, dengan perolehan gain score kelompok eksperimen yang jauh melampaui kelompok kontrol.
