This paper describes explorations into related technology and research regarding the application of interactive video projection within physical education and the gym of the future. We discuss the application of exergaming in physical education, spatial augmented reality as a technology and participatory design with teachers and children as a design method to develop new concepts. Based on our initial findings we propose directions for further research. Further work includes developing new applications based on the wishes, needs and ideas of physical education teachers and children, incorporating opportunities provided by recent technological developments.

Introduction: A trauma resuscitation is dynamic and complex process in which failures could lead to serious adverse events. In several trauma centers, evaluation of trauma resuscitation is part of a hospital's quality assessment program. While video analysis is commonly used, some hospitals use live observations, mainly due to ethical and medicolegal concerns. The aim of this study was to compare the validity and reliability of video analysis and live observations to evaluate trauma resuscitations. Methods: In this prospective observational study, validity was assessed by comparing the observed adherence to 28 advanced trauma life support (ATLS) guideline related tasks by video analysis to life observations. Interobserver reliability was assessed by calculating the intra class coefficient of observed ATLS related tasks by live observations and video analysis. Results: Eleven simulated and thirteen real-life resuscitations were assessed. Overall, the percentage of observed ATLS related tasks performed during simulated resuscitations was 10.4% (P < 0.001) higher when the same resuscitations were analysed using video compared to live observations. During real-life resuscitations, 8.7% (p < 0.001) more ATLS related tasks were observed using video review compared to live observations. In absolute terms, a mean of 2.9 (during simulated resuscitations) respectively 2.5 (during actual resuscitations) ATLS-related tasks per resuscitation were not identified using live observers, that were observed through video analysis. The interobserver variability for observed ATLS related tasks was significantly higher using video analysis compared to live observations for both simulated (video analysis: ICC 0.97; 95% CI 0.97-0.98 vs. live observation: ICC 0.69; 95% CI 0.57-0.78) and real-life witnessed resuscitations (video analyse 0.99; 95% CI 0.99-1.00 vs live observers 0.86; 95% CI 0.83-0.89). Conclusion: Video analysis of trauma resuscitations may be more valid and reliable compared to evaluation by live observers. These outcomes may guide the debate to justify video review instead of live observations.

Blog in het kader van het onderzoeksproject ‘The Network is the Message‘ Met dit onderzoek willen Hogeschool Rotterdam en Hogeschool Utrecht een antwoord geven op de vraag: “Hoe kan de effectiviteit van communicatie in online sociale netwerken worden beoordeeld en verbeterd?” In deze blog: Zoals te verwachten voor een dergelijk controversieel en politiek onderwerp is er een duidelijk onderscheid te zien tussen profit en non profit instellingen: de eerste nemen geen stelling, de tweede wel. Inhakers zijn net gewone social media posts: ze zijn vooral bedoeld om de producten en standpunten van degene die ze maakt te promoten en dat is natuurlijk prima!

Video was used in a variety of formats during a third year elective Inholland course ‘Levensbeschouwing’ at the Faculty Onderwijs en Innovatie (education and innovation) in Amstelveen. From April to June (2017), 30 part-time and full-time students on the Tweedegraads Leraren Opleiding chose to follow the course for the ten week study period. Students used a variety of video formats to support and enhance their learning process. This research evaluates how the didactic embedding of video supported the teaching and learning on the course. The objective of the research was to gain insight into the ways in which video supports the learning and teaching process in the course and into the perceived practicality and effectiveness of this video support. The research examined how video was integrated into the course structure, how students and lecturers perceived the practicality of the use of video, and whether they considered it effective. The conversational framework of Laurillard (2002), was used as a framework in which to examine the interaction between students and teachers at the conceptual and application level. An overview was made of the different forms of videos used during the course (both teacher and student generated), how they were viewed and the value of them to the students. A survey was collected on the last day of the course in which students could share feedback on the ways in which video had contributed to their learning process. At the end of the course, a group interview was held with six student representatives (one from each group) and with the lecturers on the course to collect additional qualitative feedback on how video contributed to the learning process.

The qualities and availability of different video formats offer many opportunities within the context of Higher Education (Hansch et al., 2015; Johnson et al., 2016; van Huystee, 2016). There is a shift within Higher Education to transition from the traditional face to face approach, to a more ‘blended’ approach in which face to face and online delivery of content are blended (Bates, 2015). More delivery of content is now provided online in video format, viewed before the class, as part of a flipped classroom (Bishop & Verleger, 2013; Yousef, Chatti, & Schroeder, 2014) and this is impacting the traditional role of the lecturer from ‘sage on the stage’, to ‘guide on the side’ (Tapscott, 2009). When creating video, a lecturer needs to have an understanding of the particular pedagogic affordances of the different types of video (Koumi, 2014; Thomson, Bridgstock, & Willems, 2014) and to know how to implement and embed these effectively into the teaching environment as part of a blended approach (Dankbaar, Haring, Moes, & van Hees, 2016; Fransen, 2006; Woolfitt, 2015). There needs to be awareness of how to embed the video from a didactic perspective to create meaningful learning (Karppinen, 2005) and an understanding of some of the financial and technical issues which include the relationship between cost of video production and the user experience (Hansch et al., 2015) and creating the correct combination of multimedia visual and audio elements (Colvin Clark & Mayer, 2011). As the role of the lecturer changes, there are a number of challenges when navigating through this changing educational environment. Massive Open Online Courses (MOOCs) provide lots of data for analysis and research shows that students in this environment stop watching videos after about six minutes (Guo, Kim, & Rubin, 2014) and that the most common video style used in MOOCs was the talking head with Power Point (Reutemann, 2016). Further research needs to be conducted regarding student preferences of video styles and correlation between video styles and course drop-out rates. As part of its research, the Inholland research group ‘Teaching, Learning and Technology’ (TLT) examines the use of ICT and video to support teaching and learning within Inholland. In 2015-2016, several pioneers (Fransen, 2013) working at Inholland explored different approaches to using video to support the teaching and learning process within a number of educational environments. TLT supported the pioneers in establishing their role within their faculty, creating a framework within which the pioneer can design the video intervention, collecting data and reflecting on what was learned through this process. With some of the projects, a more formal research process was followed and a full research report could be compiled. In other cases, the pioneer took a more exploratory and experimental approach. In these cases, the pioneer may not have conducted the video intervention under a formal research framework. However, during this process the pioneer may have uncovered interesting and valuable practical examples that can inspire and be shared with other educators. This current report falls under the category Research Type 3 as defined by TLT. It describes and assesses an ICT application (in this case, video) in order to share the original approach that could have high potential to be implemented in a broader educational context.

De opleiding Life Sciences & Chemistry in het domein AFL wil aansluiten bij ontwikkelingen in het werkveld en didactisch vernieuwen, gericht op de activering van studenten. Hierbij wordt van een beredeneerde inzet van video veel verwacht, vooral bij de curriculumonderdelen die studenten als lastig ervaren. De onderwijseenheid ‘Basischemie’ (blok 1, jaar 1) wordt gezien als een ‘struikelvak’. Een focusgroep met studenten maakte duidelijk dat niet alleen de stof, maar vooral ook de werkwijze in het hbo verschilt van die in de havo. Daarom is besloten tot een herontwerp van de didactiek. Doel van het onderzoek is samen met de betrokken pionier en docent die dit onderwijsonderdeel verzorgt, een uitwerking met inzet van video’s te genereren en te testen, waarbij de video’s aansluiten bij de hoorcolleges, opdat het ontwerp leidt tot actieve betrokkenheid van studenten bij het onderwijs en een beter begrip van de leerstof. Studenten vinden het logisch om voorafgaand aan een hoorcollege de video’s te bekijken en zijn positief over de gecombineerde aanpak van video’s en hoorcolleges. Het ontwerp heeft het ervaren probleem opgelost: de voorkennis is voorafgaand aan het hoorcollege geactiveerd, de oriëntatie op het hoorcollege vond plaats, en het tijd- en plaatsonafhankelijk leren is versterkt. De docent had in het hoorcollege meer tijd over voor extra verwerkingsopdrachten.

Video feedback may be a powerful tool to change biomechanical landing patterns associated with anterior cruciate ligament (ACL) injury risk. This study investigated the effect of video feedback on drop vertical jump (DVJ) landing strategies in team sport athletes. 59 athletes were assigned to a video feedback (VI) or control (CTRL) group. A pretest, 2 training sessions and a posttest were conducted. In both training sessions, video feedback, consisting of a video of the athlete's contour superimposed onto an expert's contour performing the DVJ landing task, was provided to the VI group; the CTRL group did not receive feedback. Outcomes included: kinematics and kinetics at peak knee valgus/varus moment during pre- and posttest and percentage overlap of expert and athlete during the training sessions. At posttest, males in the VI group showed greater hip flexion angles (p=0.001) and range of motion (p<0.001), smaller vertical ground reaction force, and smaller ankle dorsiflexion moment (p<0.001) compared to pretest. At posttest, males in the VI group demonstrated smaller vertical ground reaction force (p=0.031) and ankle dorsiflexion moment (p=0.001) compared to males in the CTRL group. The VI group increased percentage overlap with the expert during training sessions and from start of the first to the end of the second training session (p<0.001). Overall, video feedback was effective to modify landing strategies favorably in males. While females imitated the expert model, their landing strategy did not change significantly. While Females may need additional (verbal) feedback to benefit from video feedback.

De opleiding Pedagogiek heeft zich in de afgelopen jaren vooral gericht op didactische inzet van video in het kader van het vormgeven aan activerende didactiek. Aanleiding voor de tweede iteratie van het herontwerp zijn de aanbevelingen die voortvloeien uit de resultaten van de eerste iteratie. Ook ziet de betrokken pionier als docent de kans om tijdens lessen interactiever met de studenten aan het werk te gaan door het beredeneerd inzetten van weblectures. En docenten willen hiermee studenten faciliteren en activeren om in eigen tijd en op een zelfgekozen plaats de benodigde kennis te verwerven. De centrale vraag was hoe het didactisch ontwerp van onderwijseenheid ‘Literatuurstudie’ als onderdeel van de conceptuele leerlijn in jaar 1, blok 3 in de opleiding Pedagogiek eruit ziet. Een ontwerp waarin beoogd wordt met de inzet van weblectures en een andere invulling van contacttijd bij te dragen aan activering van de student en versterking van de interactie tussen docent en student. Hierbij voelt de docent zich eigenaar van het ontwerp en acht zich ook in staat het ontwerp in de praktijk te realiseren.

The research examined the ways in which Student Generated Video supported the learning process on the course ‘Levensbeschouwing’ (Life Philosophy) on the third year on the teacher training course at Inholland in Amsterdam. The central question examined was: In which ways does the student generated video on the Inholland course ‘Life Philosophy’ contribute to students gaining insight, developing deeper knowledge, and achieving the course learning goals? The 30 students on the course participated in the research. During the course, they were involved in creating three video interviews per project group that examined the question of life philosophy from the perspective of personal life, life philosophy traditions and school life. Video production was segmented into four phases; pre-production, production, post-production and reflection. At each phase, students answered short open questions online, and on the final day completed a survey. A group of seven students participated in a group interview on the final day.
