The present study was aimed at investigating the effects of a video feedback coaching intervention for upper-grade primary school teachers on students’ cognitive gains in scientific knowledge. This teaching intervention was designed with the use of inquiry-based learning principles for teachers, such as the empirical cycle and the posing of thought-provoking questions. The intervention was put into practice in 10 upper-grade classrooms. The trajectory comprised four lessons, complemented with two premeasures and two postmeasures. The control condition consisted of 11 upper-grade teachers and their students. The success of the intervention was tested using an established standardized achievement test and situated measures. In this way, by means of premeasure and postmeasure questionnaires and video data, an assessment could be made of the change in students’ scientific knowledge before, during, and after the intervention. In this study, we primarily focused on the dynamics of students’ real-time expressions of scientific knowledge in the classroom. Important indicators of the effect of the intervention were found. Through focusing on the number of explanations and predictions, a significant increase could be seen in the proportion of students’ utterances displaying scientific understanding in the intervention condition. In addition, students in the intervention condition more often reasoned on higher complexity levels than students in the control condition. No effect was found for students’ scientific knowledge as measured with a standardized achievement test. Implications for future studies are stressed, as well as the importance of enriching the evaluation of intervention studies by focusing on dynamics in the classroom.

Uit onderzoek blijkt de kwaliteit van de leraar voor de klas de meest belangrijke factor is op het leerresultaat van leerlingen.Leraarschap is een professie en net als andere professionals moeten leraren hun vak bijhouden en constant hun eigen handelen evalueren en verbeteren. Soms gaat dat vanzelf, bijvoorbeeld bij beginnende leraren. Om te overleven, zijn zij gedwongen heel snel te leren en zich verder te ontwikkelen. Maar meer ervaren leraren hebben inmiddels allerlei routines opgebouwd en missen vaak wat Koffeman (2011) noemt de 'noodzaak tot leren'. Het proefschrift beschrijft mogelijkheden om de professionalisering van leraren te stimuleren door middel van reflectiegesprekken met collega's en het gebruik van videofeedback. Het proefschrift betreft een ontwerponderzoek met als doel: op onderzoek gebaseerde oplossingen te ontwikkelen voor complexe problemen uit de onderwijspraktijk en tevens bij te dragen aan wetenschappelijke theorievorming, door het bestuderen van de onderliggende ontwerpprincipes. Samen met een school voor voortgezet onderwijs is een concreet programma ontworpen dat meer informele vormen van leren op de werkplek tussen leraren stimuleert. Door het ontwerpproces en de uitkomsten stap voor stap te beschrijven, levert dit onderzoek niet alleen een kant-en-klaar professionaliseringsprogramma dat andere scholen kunnen gaan gebruiken, maar levert het vooral ook bouwstenen op in de vorm van ontwerpprincipes en kennis over hoe en onder welke voorwaarden deze in de school kunnen werken. Met deze bouwstenen worden ook andere scholen in staat gesteld om het programma aan te passen aan de context van de eigen school.

Our research aims to formulate design guidelines for stimulating teachers' professional development using video feedback in collaborative settings. The study investigates guidelines concerning video feedback in peer coaching settings and focuses on a setting with three roles (of trainee, coach and observer), (c) coach training, (d) ownership of learning goals and (e) focus on outcomes in classroom. A scheme was developed consisting of six coach training sessions and of peer reciprocal coaching in subgroups with video feedback of classroom performances. Within these subgroups three teachers took turns in different roles: as trainee, as coach and as observer of the coaching dialogue. The study explores the coach's roles that are beneficial for the learning process of their peers and seeks to understand how watching video records of own practice supports teachers to examine their own professional behaviour in new ways. Data for this study includes videotaped and transcribed subgroup dialogues and, for triangulation, data from learning reports, audio tapes and observational notes of the training sessions, questionnaires, and in-depth semi-structured interviews with all participants. Coaching in a setting with three well defined roles (trainee, coach, observant) proved valuable. The coach role was very important for the depth of the reflection process. Non-directive coaching skills created necessary safety and space for learning, but more directive coaching skills such as 'Continue to ask questions' were necessary to deepen the reflection process from more descriptive and perceptive reflections to more receptive, interactive and critical reflections. In the dialogues the participants reflect on practice, on context, on values, and on improvements. Working with (peer) observers of the coaching dialogs improved performance and forced the group to take their roles more seriously. Essential for the scheme to work is a high degree of equality between participants.

Meetings with other professionals are considered crucial for enhancing the quality of teachers' reflections. However, little is yet known about how any beneficial effects of such meetings are brought about. This study explores the peer coach's roles and their influences on the learning processes of their peers and seeks to understand how watching video records of own practice, supports teachers to examine their own professional behaviour in new ways. Within subgroups three teachers took turns in different roles: as trainee, as coach and as observer of the coaching dialogue. They used video recordings of the interactions in their classrooms as feedback. Data for this study included videotaped and transcribed group dialogues and, for triangulation, data from learning reports, questionnaires, and in-depth semi-structured interviews with all participants. Coaching promoted broadening the scope of their reflections. Teachers often started just describing work situations with technical reflections on 'how to'. Non-directive coaching skills created necessary safety and space for learning, but video feedback and more directive coaching skills such as 'Continue to ask questions' were necessary to deepen the reflection process and to relate reflections with analysis of feelings, perspectives of other actors, and with political notions concerning social, moral and political issues. Peer coaching with video feedback affords positive impact to those who coach in addition to those who receive the coaching. Understanding different forms of teacher learning provides insight for research on teacher cognition and may inform the design of video-based professional development.

Deze handleiding hoort bij het onderdeel “Coaching-in-de-klas” van het professionaliseringsprogramma ’t PASST Samen. In ’t PASST Samen werken leerkrachten en jeugdhulpverleners (professionals) aan het versterken van hun handelen en hun interprofessionele samenwerkingsvaardigheden. Het doel daarvan is dat de betrokkenheid bij het leren van kinderen met een autismespectrumstoornis (ASS) vergroot wordt. Leerkrachten en jeugdhulpverleners ontwikkelen nieuwe kennis en vaardigheden die ze direct kunnen toepassen in hun werk. Hierdoor wordt hun handelingskracht om een integrale aanpak vorm te geven versterkt. Dit levert uiteindelijk tijdwinst op, omdat er preventief gewerkt wordt aan problemen die samenhangen met een verlaagde betrokkenheid (bijv. interactieproblemen). Hierdoor worden de kansen voor kinderen met ASS vergroot. ’t PASST Samen is bedoeld voor leerkrachten en jeugdhulpverleners die met leerlingen met ASS werken én hun integrale aanpak voor deze leerling(en) willen versterken. De professionalisering is geschikt voor zowel ervaren als minder ervaren professionals. Van belang is dat de professional open staat voor: coaching en reflectie; het werken aan eigen leerdoelen en -vragen; uitwisselen van kennis en ervaringen met collega’s binnen en buiten de eigen organisatie en het delen van kennis en ervaringen met ouders. Naast de leerkracht/jeugdhulpverlener wordt ook een coach (bijvoorbeeld de gedragsdeskundige, beeldcoach, video-interactiebegeleider, intern begeleider) van de organisatie betrokken om de leerkracht/jeugdhulpverlener te ondersteunen. Van belang is dat de coach het als een uitdaging ziet de professionals van de organisatie te coachen. Daarnaast is de coach bereid om te participeren in de train-de-coach-sessies waarbij kennis en ervaringen worden opgefrist, gedeeld en toepasbaar gemaakt voorde eigen praktijk. Om veranderingen in het onderwijs en de jeugdhulpverlening te realiseren is het belangrijk om de organisatie mee te nemen in het leerproces: de collega’s en deleidinggevende. Zo kan het effect van de professionalisering vergroot worden. Voor meer informatie over ’t PASST Samen raadpleeg de Algemene Handleiding.

Many studies have shown that self-controlled feedback is beneficial for learning motor tasks, andthat learners prefer to receive feedback after supposedly good trials. However, to date all studiesconducted on self-controlled learning have used individual tasks and mainly relatively simpleskills. Therefore, the aim of this study was to examine self-controlled feedback on tactical skills insmall-sided soccer games. Highly talented youth soccer players were assigned to a self-control oryoked group and received video feedback on their o ffensive performance in 3 vs. 2 small-sidedgames. The results showed that the self-control group requested feedback mostly after good trials,that is, after they scored a goal. In addition, the perceived performance of the self-control groupwas higher on feedback than on no-feedback trials. Analyses of the conversations around thevideo feedback revealed that the players and coach discussed good and poor elements of per-formance and how to improve it. Although the coach had a major role in these conversations, theplayers of the self-control group spoke more and showed more initiative compared to the yokedgroup. The results revealed no significant beneficial effect of self-controlled feedback on per-formance as judged by the coach. Overall, the findings suggest that in such a complex situation assmall-sided soccer games, self-controlled feedback is used both to confirm correct performanceelements and to determine and correct errors, and that self-controlled learning stimulates theinvolvement of the learner in the learning process.

The artcle describes the outcomes of a pilot study on professional development of teachers. The project was initiated by the school management. Nine teachers volunteered to work on their professional development in a programme consisting of: meetings discussing on relevant teacher topics meetings discussing video fragments of own performances meetings exploring ways to coach each other and how to use videotapes for feedback peer-coaching-sessions in small groups. Within these groups three teachers took turns in different roles: trainee, coach and observer. Aims of the study are: to develop a coaching programme, to describe extensively the process and the outcomes in order to identify the main factors influencing the learning processes of teachers in peer coaching settings with video feedback.

This design study aimed to develop and test a coherent set of guidelines for teacher professional development. Based on literature we settled for five main principles, and translated these into guidelines for a teacher professional development program. To realize (1) feedback on classroom practice we incorporated video observation. The program was built around (2) collaborative professional learning within reciprocal peer coaching, with (3) teachers as inquirer focusing on student outcomes, (4) teachers' ownership of own learning goals, and (5) training for professional learning. The program was developed and executed in two groups. All complementary guidelines appeared useful. Teachers need time to develop coaching skills, and find inquiring difficult. Video feedback stimulates teacher learning, especially when embedded in coaching. The program helped participants in learning through interaction and reflection focusing on classroom practice. While the voluntary group evaluated the program more positive, the non voluntary group showed more change.

Background: In team handball an anterior cruciate ligament (ACL) injury often occurs during landing after a jump shot. Many intervention programs try to reduce the injury rate by instructing the athletes to land safer. Video feedback is an effective way to provide feedback although little is known about its influence on landing technique in sport-specific situations. Objective: To test the effectiveness of a video overlay feedback method on landing technique in elite handball players. Method: Sixteen elite female handball players were assigned to a Control or Video Group. Both groups performed jump shots in a pre-test, two training sessions (TR1 & TR2) and a post-test. The Video Group received video feedback of an expert model with an overlay of their own jump shots in TR1 and TR2 whilst the Control Group did not. Main outcome measures were sagittal ankle, knee and hip angles during initial contact (IC), maximum (MAX) and range of motion (ROM), in addition to the Landing Error Scoring System (LESS) score. One 2x4 repeated measures ANOVA was conducted to analyze group, time and interaction effects of all kinematic outcome measures and the LESS score. Results: The Video Group displayed significant improvement in knee and hip flexion at IC, MAX and ROM. In addition, MAX ankle flexion and their LESS score improved an average of 8.1 in the pre-test to 4.0 in the post-test. When considering performance variables, no differences between Control Group and Video Group were found in shot accuracy or vertical jump height, whilst horizontal jump distance in the Video Group became greater over time. Conclusion: Overlay visual feedback is an effective method to improve landing kinematics during a sport-specific jump shot. Further research is now warranted to determine the long-term effects and transfer to training and game situations.

Living a sedentary lifestyle is one of the major causes of numerous health problems. To encourage employees to lead a less sedentary life, the Hanze University started a health promotion program. One of the interventions in the program was the use of an activity tracker to record participants' daily step count. The daily step count served as input for a fortnightly coaching session. In this paper, we investigate the possibility of automating part of the coaching procedure on physical activity by providing personalized feedback throughout the day on a participant's progress in achieving a personal step goal. The gathered step count data was used to train eight different machine learning algorithms to make hourly estimations of the probability of achieving a personalized, daily steps threshold. In 80% of the individual cases, the Random Forest algorithm was the best performing algorithm (mean accuracy = 0.93, range = 0.88–0.99, and mean F1-score = 0.90, range = 0.87–0.94). To demonstrate the practical usefulness of these models, we developed a proof-of-concept Web application that provides personalized feedback about whether a participant is expected to reach his or her daily threshold. We argue that the use of machine learning could become an invaluable asset in the process of automated personalized coaching. The individualized algorithms allow for predicting physical activity during the day and provides the possibility to intervene in time.
