Abstract

This research aims to produce high school mathematics learning tools to improve students' critical thinking skills which include Student Worksheets (LKPD), and learning outcome assessment test sheets that are valid, practical and effective. The combination of learning methods and technological devices provides a fun learning process and helps students improve their critical thinking skills so as to provide benefits to students' learning outcomes. The type of research carried out is the research and development method. The development model referred to is using a 4-D development model which consists of four stages, namely the define stage, the design stage, the develop stage and the disseminate stage. The research instruments used were validation sheets, teacher practicality sheets, student practicality sheets, learning implementation observation sheets, and test sheets. The research data obtained that the level of device validity was in the valid category with an average score of 74.5. The teacher obtained a score of 60.5 for practicality and 61.88 for student practicality, so that the product met the practical category, and the results of students' mathematics learning achievement tests in the field trial showed that 83.3% of students had achieved the Minimum Completeness Criteria (KKM) so that the product The worksheet meets the effective category. Based on the obtained validity, practicality and effectiveness figures, it can be concluded that the learning tools developed are suitable for use in the classroom learning process.

Abstract

Penelitian ini bertujuan untuk mendeskripsikan pengaruh penerapan model pembelajaran Contextual Teaching and Learning (CTL) berbantuan Teka-Teki Silang (TTS) terhadap hasil belajar kimia. Jenis penelitian ini adalah penelitian eksperimen dengan one group pretest posttest design. Populasi penelitian ini adalah seluruh mahasiswa Jurusan Pendidikan Kimia Semester 3 yang terdiri dari 13 orang. Analisis data menggunakan independent sample t-test. Hasil penelitian diperoleh thit = 7,27 lebih besar dari nilai ttabel = 1,78 yang berarti bahwa H0 ditolak dan Ha diterima, sehingga dapat disimpulkan bahwa terdapat pengaruh model pembelajaran CTL berbantuan TTS terhadap hasil belajar kimia.

Abstract

This study examines the effect of Social Media Marketing Activities on Purchase Decision through Brand Equity in the context of Catholic educational institutions under Yayasan Pendidikan dan Persekolahan Katolik Merauke. A quantitative explanatory approach was applied by involving 100 parents whose children study at YPPK schools. Data were collected using a structured questionnaire with a five-point Likert scale. Social Media Marketing Activities were measured through social media understanding, entertainment, interaction, trendiness, customization, and word of mouth. Brand Equity was measured through brand awareness, brand association, brand loyalty, and perceived quality, while Purchase Decision was measured through school choice decision, confidence in school choice, and willingness to recommend the school. The findings show that Social Media Marketing Activities have a significant effect on Purchase Decision, although the direct relationship is negative. Social Media Marketing Activities have a positive and significant effect on Brand Equity, and Brand Equity has a positive and significant effect on Purchase Decision. Furthermore, Brand Equity partially mediates the relationship between Social Media Marketing Activities and Purchase Decision. This study contributes to educational marketing literature by positioning Brand Equity as a key mechanism that explains how social media activities influence parents’ school choice decisions. The study offers originality by examining digital marketing, brand equity, and school choice decisions in Catholic educational institutions, a context rarely examined in previous social media marketing studies. YPPK should manage social media not merely as promotional media, but as a strategic instrument to strengthen reputation, trust, perceived quality, and institutional values.
