The Centre for Schooling and Learning Technologies (CSaLT) at Edith Cowan University (ECU) was asked in 2016 to be the Western Australian arm of a national e-exam project. This project used a bespoke exam system installed on a USB-drive to deliver what would have been traditional paper-based exams in an enclosed computer-based environment that was isolated from the internet and any resources other than those provided by the lecturer. This paper looks at the two exams chosen by the Western Australian group for the trial; a programming exam for pre-service computing teachers and an occupational health and safety exam for pre-service design and technology teachers. Both groups were drawn from the Graduate Diploma in Education course at ECU. The paper looks at the nature of the exam environment and the procedure for creating e-exams. It also outlines the exam procedures used and examines the feedback provided by both the lecturers and students involved. Conclusions are drawn about the suitability of the e-exam system and improvements are recommended as well as a discussion about e-exams and digital assessment more generally.

Floral plantings are promoted to foster ecological intensification of agriculture through provisioning of ecosystem services. However, a comprehensive assessment of the effectiveness of different floral plantings, their characteristics and consequences for crop yield is lacking. Here we quantified the impacts of flower strips and hedgerows on pest control (18 studies) and pollination services (17 studies) in adjacent crops in North America, Europe and New Zealand. Flower strips, but not hedgerows, enhanced pest control services in adjacent fields by 16% on average. However, effects on crop pollination and yield were more variable. Our synthesis identifies several important drivers of variability in effectiveness of plantings: pollination services declined exponentially with distance from plantings, and perennial and older flower strips with higher flowering plant diversity enhanced pollination more effectively. These findings provide promising pathways to optimise floral plantings to more effectively contribute to ecosystem service delivery and ecological intensification of agriculture in the future.
