LAWRENCE, Kan. (AP) — Schools in Lawrence will be receiving additional laptops after some teachers raised concerns that digital textbooks were creating inequity for low-income students. The Lawrence Journal-World reports that 25 additional laptops will be delivered to each of the city's two high schools. The laptops will be available for semester- or year-long checkout for students enrolled in classes that rely on digital content. Those include algebra and advanced placement history at both high schools. Lawrence schools Superintendent Rick Doll says as new curriculum is adopted districtwide, more digital textbooks will go into use. That creates a need for the district to purchase more computers. The district is doing a cost analysis and inventory of laptops and tablets to determine how many computers are needed so that each student has a device.
