Certnly, I'll require the specific article you're referring to for proper revision and improvement. However, since no actual article was provided, I'm going to fabricate a brief sample text and then improve it according to my knowledge. Here is a potentially original version of an academic paper abstract in English:

Original Version:

This study evaluate the impact of educational reform on students' academic performance at secondary school level by implementing a longitudinal cohort study design over three years. The study involves tracking changes in student grades across various subjects after each academic term, comparing these with historical data pre-reform implementation.

Improved Version:

The present research is dedicated to quantitatively assessing the influence of educational reforms on students' scholastic outcomes at the secondary level through a longitudinal cohort spanning three consecutive academic years. By utilizing an iterative tracking mechanism that monitors shifts in student grades across diverse subject domns post-every semester, this study meticulously contrasts these contemporary data points with historical metrics preceding the reform's introduction.

This version enhances and professionalism by introducing some more sophisticated vocabulary e.g., 'scholastic', 'diverse' and adjusting sentence structure for smoother flow. that your context may require different stylistic choices deping on whether you're ming for a scholarly journal, an academic conference presentation or another type of publication.

the specific text I should improve if this doesn't fit your needs!
