The effectiveness of blended learning was evaluated through the integration of an online chemistry platform, LabLessons. Two modules, Formation of were designed by college mentors alongside classroom chemistry teachers to engage and allow high school students to better comprehend these scientific topics. The pre-lab modules introduced the students to experiments they were expected to perform in class the following day. | Journal of Technology and Science Education JOTSE, 2018 – 7(2): 34-44 – Online ISSN: 2013-6374 – Print ISSN: 2014-5349 PERSPECTIVES ON BLENDED LEARNING THROUGH THE ON-LINE PLATFORM, LABLESSONS, FOR CHEMISTRY Teeba Jihad1 1 , Edward Klementowicz1 , Patrick Gryczka2 , Chappel Sharrock3 Maxfield4 , Yongjun Lee4 , Jin Kim Montclare1,3,5 , MacRae Department of Chemical and Biomolecular Engineering, New York University Tandon School of Engineering (United States) 2 Department of Computer Science and Engineering, New York University Tandon School of Engineering (United States) 3 Department of Chemistry, New York University College of Arts and Science (United States) 4 5 Department of Chemistry, Brooklyn Technical High School (United States) Department of Biomaterials, New York University College of Dentistry (United States) tj584@, ewk235@, patrick@, cs3682@, Mmaxfield@, Ylee12@, montclare@ Received August 2017 Accepted January 2018 Abstract The effectiveness of blended learning was evaluated through the integration of an online chemistry platform, LabLessons. Two modules, Formation of Hydrogen and Titration, were designed by college mentors alongside classroom chemistry teachers to engage and allow high school students to better comprehend these scientific topics. The pre-lab modules introduced the students to experiments they were expected to perform in class the following day. The modules consisted of an introduction as well as either a visualization and/or simulation specific to each topic. Students and teachers who utilized LabLessons were surveyed to establish a preliminary research on the use of technology in classrooms. Student and teacher surveys demonstrated LabLessons to be an interactive and helpful tool to improve students' understanding of conceptual ideas.
