Abstract:

This study developed and validated a web-based self-assessment tool (WebSAT) in general chemistry. The WebSAT for college students is an innovative self-assessment tool that features individualized questions and study plans; automatic grading and immediate feedback; interactive involvement with the material in computers and smart phones. An added feature of the WebSAT is that it allows the learners to check the accuracy of their work and to resubmit their answers. The system utilized PHP as programming language, MySQL as database and Adobe Dreamweaver as Integrated Environment Development (IDE). Using quantitative and qualitative methods, the IT experts, chemistry teachers and the learners evaluated the WebSAT and found it beneficial as a formative evaluation material. They liked its flexibility and immediate feedback and concluded that it was easier to use compared with the conventional self-assessment tool. IT experts and teachers found it useful and can be generalized in other courses. Learners using WebSAT reported being more interested to do well in the course. The result showed that there was a significant difference between the pre-test and post-test with WebSAT use. The post-test result indicated that the material was very effective.
