The intends to promote students’ scientific literacy. aim paper is examine effectiveness specially designed online worksheets (e-WS) actively engage students in design unconfounded experiments by applying Control Variables Strategy (CVS). Second-year senior high school (11th grade) participated intervention which approach with asynchronous synchronous distance sessions were adopted, during COVID-19 lockdown.
