The dissection film has clear benefits-increasing PA and self-efficacy-that come at the cost of higher NA and higher STAI-S. The life history group showed no differences between the pretest and posttest 1. The dissection film group scored higher in PA, NA, and state anxiety (STAI-S) after the dissection video treatment and higher in self-efficacy after the dissection. We applied a pre/posttest treatment-comparison design and used the Positive and Negative Affect Schedule (PANAS), the State–Trait–Anxiety Inventory for State (STAI-S), and a self-efficacy measure three times: before the lesson (pretest), after the film treatment (posttest 1), and after the dissection (posttest 2).
Seventy received the treatment with the dissection video, and 65 viewed the life history video. The participants were 135 students studying to become biology teachers.
We compared this treatment with another group that watched a life history video about the fish. We aimed at reducing negative emotions (anxiety, negative affect ) and increasing positive affect (PA) and self-efficacy by an experimental intervention using a predissection video to instruct students about fish dissection. Results indicate that Anatomy Studio encourages closely-coupled collaborations and group discussion, to achieve deeper insights.In science education, dissections of animals are an integral part of teaching, but they often evoke negative emotions. A user study including experienced anatomists and medical professionals, conducted in real working sessions, demonstrates that Anatomy Studio is appropriate and useful for 3D reconstruction. By using mid-air interactions and interactive surfaces, anatomists can easily access any cryosection and edit contours, while following other user’s contributions. We contribute novel interaction techniques intended to promote spatial understanding and expedite manual segmentation.
In this work, we present Anatomy Studio, a collaborative Mixed Reality tool for virtual dissection that combines tablets with styli and see-through head-mounted displays to assist anatomists by easing manual tracing and exploring cryosection images. However, conventional user interfaces rely on single-user experiences and mouse-based input to create content for education or training purposes. 3D reconstruction from anatomical slices allows anatomists to create three dimensional depictions of real structures by tracing organs from sequences of cryosections.
