TULSA, Okla. (Reuters) - The Oklahoma House of Representatives approved a $20 million internet sales tax on Wednesday as part of a revenue package aimed at ending a statewide walkout by teachers seeking higher pay and more education funding.

The walkout, now in its third day, is the latest upheaval by teachers in a Republican-dominated state after a successful West Virginia strike last month ended with a pay raise. More than 100 school districts in Oklahoma will remain shuttered on Thursday.

Lawmakers approved the tax measure as hundreds of teachers, parents and students packed the Capitol in Oklahoma City to press for a $200 million package to raise education spending in Oklahoma, which ranks near the bottom for U.S. states.

“This is a win for students and educators and signals major progress toward funding the schools our students deserve,” Alicia Priest, head of the Oklahoma Education Association, the teachers union, said in a statement after 92 lawmakers approved the sales tax measure.

Across the state, protests were held near schools and along streets, with demonstrators holding signs bearing slogans such as “35 is a speed limit, not a class size.”

The tax bill requires third-party vendors on internet sites such as Amazon to remit state sales taxes on purchases made by residents.

The bill now goes to the Senate, where lawmakers on Thursday will weigh a measure expanding gaming at Native American casinos as part of the $200 million package. Lawmakers are also weighing such options as repealing exemptions for capital gains taxes.

The teachers’ protests reflect rising discontent after years of sluggish or declining public school spending in Oklahoma, which ranked 47th among the 50 states in per-student expenditure in 2016, according to the National Education Association.

Kentucky teachers also have demonstrated against stagnant or reduced budgets by a Republican-controlled legislature. Arizona educators have threatened similar job actions.

“My books were old when I was in high school more than 15 years ago and chances are a lot of them are still being used today,” Oklahoma City resident Ashley Morris said by telephone from a statehouse rally.

“Students just aren’t getting what they need or deserve and that puts teachers in a tough situation,” said Morris, whose roommate is a first-grade teacher who relies on a second job to make ends meet.
