Early Childhood Development (ECD) practitioners' lesson plans adapted using the three universal design for learning (UDL) principles before and after the intervention training

This dataset was collected using the quantitative method. The single-group pre-test post-test design was used.The dataset on the spreadsheet provided entails what each participant (7 participants in total) scored for each universal design for learning (UDL) principles namely: representation, expression and engagement on their pre-test and post-test lesson plans. The mean and standard deviation scores for each UDL principles for the pre-test and post-test are also included in the dataset spreadsheet.本数据集采用定量研究方法采集，采用单组前测-后测实验设计。本次提供的电子表格数据集涵盖了全部7名参与者针对通用学习设计（Universal Design for Learning, UDL）三大原则——表征、表达与参与——在课前教案与课后教案中的得分情况。数据集电子表格中同时收录了各通用学习设计原则在前测与后测环节的平均分与标准差统计结果。
