摘要

Penelitian ini didasarkan pada rendahnya kemampuankoneksi matematis siswamenengahkejuruanpertanianyang menekankan pada kemampuan siswa untuk menggunakan kemampuan matematisnya dalam bidangpertaniandandalamkehidupan sehari-hari.

It considered students in an agricultural SMK both as a whole and in groups based on early mathematics ability (KAM). The study also compared the habits of mind of students engaged in project-based learning to those taught by conventional methods. It used a quasi-experimental design with a non-equivalent control group involving 60 students in Class XI at SMK Negeri Agricultural Development in Tanjungsari, West Java. Instruments used included pre-test, post-test, scale of habits of mind of students, and observation forms. Statistical analysis was conducted using independent sample t-test, Mann-Whitney test, one-way ANOVA test, and two lines. The study yielded the following results: (1) Students engaged in project-based learning showed a increased ability for mathematical connections compared to those engaged in conventional learning. (2) Students engaged in project-based learning showed an increased ability for mathematical connections compared to KAM students. (3) Learning and KAM showed no interactive effect in increasing student’s ability for mathematical connections. (4) Students engaged in project-based learning showed a higher quality of mathematical connections. (5) Students engaged in project-based learning showed improved habits of mind compared with those engaged in conventional learning. ududKeywords: mathematical connections, project-based learning, habits of mind.
