There are a lot of free online resources that you can use to further enhance your research and information gathering. The following list is just one of the many free online resources that you can use. Wikipedia - this is still the best online encyclopedia. But due to the nature of how the encyclopedia contents are created, there is a chance that the data published is not accurate. Use this site as a good start for the subject matter and expand the information gathered from other reputable websites. Library Genesis - here you can find a good collection of electronic books (e-books) which you can download freely. Just be careful of any copyrighted material that may be available in this site. Google Scholar - Google Scholar will search for different published scholarly literature. There are many sources of literature that can be searched online from but not limited to articles, theses, books, abstracts and court opinions
I created this blog to document the materials I used in teaching the subject Empowerment Technologies for the Senior High School in the Philippines. Due to the limited information and teaching guides available in teaching this subject, I hope I can contribute a little to the development of this course.
