Abstract

The main objective of this research is to investigate the effectiveness of a learning management model for enhancing digital skills, creative problem-solving, analytical thinking, and achievement motivation among higher vocational certificate students. This is an analytic-descriptive study. A sample group of 30 second-year higher vocational certificate students was chosen via cluster random sampling. Classrooms were used as the sampling units. The research instruments included the learning management model, a digital skills assessment scale, a creative problem-solving assessment scale, an analytical thinking ability assessment scale, and an academic achievement motivation assessment scale. The statistics used for data analysis were percentages, means, standard deviations, and t-tests (dependent samples) to test for differences in means. The research findings revealed the following: the students' digital skills after receiving instruction using the model were significantly higher than before receiving instruction, at the .05 level; the students' creative problem-solving scores after receiving instruction using the model were significantly higher than before receiving instruction, at the .05 level; the students' critical thinking ability after receiving instruction using the model was significantly higher than before receiving instruction, at the .05 level; the students who received instruction using the model demonstrated achievement motivation that was overall at a high level.

Keywords: Instructional model, digital skills, creative problem-solving, critical thinking, achievement motivation.
