Kajian ini dijalankan untuk menentukan kesahan dan kebolehpercayaan item dimensi kebolehgunaan Padlet dalam mengaplikasi Model Trialogical melalui teknik pengukuran Rasch. Dimensi kebolehgunaan mengandungi adaptasi konstruk yang dibangunkan mengandungi aspek kecekapan, keberkesanan dan kepuasan pelajar. Kajian ini menggunakan dapatan kajian penulis yang lepas berdasarkan dapatan penilaian kuantitatif berkaitan kebolehgunaan aplikasi Padlet dalam mengaplikasi model Trialogical bagi kursus xxx3152 Inovasi Digital dalam Pengajaran dan Pembelajaran yang melibatkan kajian rintis kepada14 orang pelajar semester 6 di IPG Kampus Pendidikan Teknik (IPGKPT). Hasil kajian ini menjelaskan kesahan item yang dibangunkan berdasarkan dapatan rintis yang telah dijalankan menggunakan ujian diagnostik nilai indeks Cronbach Alpha dan diagnostik kebolehpercayaan, unidimensi, polariti item PtMea-Corr, diagnostik kesesuaian item dan diagnostik item map. Berdasarkan dapatan kajian, secara lanjut kualiti item mempunyai kesahan dan kebolehpercayaan yang baik untuk mengukur tiga konstruk dimensi kebolehgunaan berkaitan penggunaan aplikasi Padlet dalam mengaplikasi model Trialogical bagi PdP.
Abstract
This study was conducted to determine the validity and reliability of the Padlet usability dimension items in applying the Trialogical Model through Rasch measurement technique. The usability dimension contains the adaptations of developing constructs containing aspects of student efficiency, effectiveness and satisfaction. This study uses the findings of the author's previous study based on the findings of quantitative evaluation related to the usability of the Padlet application in applying Trialogical model for the course xxx3152 Digital Innovation in Teaching and Learning which involved a pilot study to 14 of semester 6 students at IPG Kampus Pendidikan Teknik (IPGKPT). The results of this study explain the validity and reliability of items developed based on pilot findings that have been conducted using index Cronbach Alpha reliability diagnostics, unidimensional, PtMea-Corr item polarity, diagnostic items suitability and diagnostics item map. Based on the findings of the study, item quality has good validity and reliability in measuring the three dimensional constructs of Padlet application usability in applying Trialogical model to PdP course.
