title: Video based observation in master chef role plays
abstract: The 21st century has witnessed significant changes in the context of language teaching or learning as the world is increasingly globalized and digitalized. Therefore, students in vocational colleges are demanded to learn the skills to be able to survive and succeed in today's world as both a local and global citizen. The objective of this study was to implement the role plays' technique of video recording to improve the student's speaking ability. In conducting the research, there were two components expected to be improved, namely the teaching learning process to be conducive and the students' speaking scores. By applying classroom action research, data were collected in two cycles of learning. The result of the speaking test revealed that the students had made some progress, which was shown by the increase of students' average speaking scores. The improvement of the scores was also followed by the increase of students learning interest and motivation in a conducive teaching learning atmosphere.

title: Video based observation in sport: From "forgotten" to ubiquitous
abstract: Demonstrations have been recognized as a useful tool for helping people learn new skills and for modifying psychological responses such as anxiety, confidence, and motivation. However, the use of video based demonstrations has been overlooked in the sport psychology literature. With advances in computer and mobile technology it is now possible to film, edit, and provide athletes with real time feedback on many types of behaviors within real life settings. This article provides an overview of video based observation in sport as well as practical tips and examples for mental performance consultants, coaches, and other movement practitioners for how they might use video to modify not only sport skills but also psychological behaviors.

title: Video based observation and feedback for Thai in service teachers the mentor's role
abstract: There is good evidence that a mentor (i.e. a relatively experienced teacher) who provides professional support to a relatively inexperienced teacher (i.e. a mentee) can effectively support professional development (e.g. Hobson and Malderez 2013) This article focuses on aspects of the mentoring role within a teacher development initiative in Thailand. External mentors worked with English language teachers as a follow up to a three week INSET course (nicknamed 'bootcamp' by the Thai Ministry of Education) Mentors reinforced content from this INSET course and guided teachers using a video reflection process supported by an online platform (Iris Connect) This article analyses both interviews with mentors and Thai teachers, as well as recordings of teacher mentor discourse and video club meetings. This data comes from a process where mentors guided reflection on both videos of a teacher's own teaching and videos of other Thai teachers through online and face to face discourse. We consider aspects of the mentor's role, identity and interaction. Interviews reveal some of the challenges and affordances that video provided in this process. In summary, this article

title: Video based observation in language teacher education
abstract: In this series, we explore technology related themes and topics. The series aims to discuss and demystify what may be new areas for some readers and to consider their relevance for English language teachers.

title: Using video based observation research methods in primary care health encounters to evaluate complex interactions.
abstract: The purpose of this paper is to describe the use of video based observation research methods in primary care environment and highlight important methodological considerations and provide practical guidance for primary care and human factors researchers conducting video studies to understand patient clinician interaction in primary care settings.  We reviewed studies in the literature which used video methods in health care research, and we also used our own experience based on the video studies we conducted in primary care settings.  This paper highlighted the benefits of using video techniques, such as multi channel recording and video coding, and compared "unmanned" video recording with the traditional observation method in primary care research. We proposed a list that can be followed step by step to conduct an effective video study in a primary care setting for a given problem. This paper also described obstacles, researchers should anticipate when using video recording methods in future studies.  With the new technological improvements, video based observation research is becoming a promising method in primary care and HFE research. Video recording has been under utilised as a data collection tool because of confidentiality and privacy issues. However, it has many benefits as opposed to traditional observations, and recent studies using video recording methods have introduced new research areas and approaches.

title: The development of small, cabled, real time video based observation systems for near shore Coastal Marine Science including three examples and lessons learned
abstract: The effects of climate change on the near shore coastal environment including ocean acidification, accelerated erosion, destruction of coral reefs, and damage to marine habitat have highlighted the need for improved equipment to study, monitor, and evaluate these changes  This is especially true where areas of study are remote, large, or beyond depths easily accessible to divers. To this end, we have developed three examples of low cost and easily deployable real time ocean observation platforms. We followed a scalable design approach adding complexity and capability as familiarity and experience were gained with system components saving both time and money by reducing design mistakes. The purpose of this paper is to provide information for the researcher, technician, or engineer who finds themselves in need of creating or acquiring similar platforms.

title: A Video Based Observation Method to Assess Musculoskeletal Load in Kitchen Work
abstract: This paper describes a new video based observation method aimed to assess musculoskeletal load in kitchen work, aspects of its repeatability and validity, and problems confronted by the observers. Two pairs of researchers observed individually 117 video clips recorded in kitchens. Interobserver repeatability was assessed by computing the proportion of agreement and weighted kappa values (kw) Validity was analyzed by studying the distribution of the assessments over the rating scales and the ratings before and after the interventions, which were compared with expert assessments made from the same intervention targets. The proportion of agreement ranged from 57 to 88% Interobserver repeatability based on weighted kappa values was mainly good to moderate. The method detected the changes in physical load due to the interventions. Direction of the changes corresponded with the expert assessments. Further development of the method is needed to assess the load on the hands and wrists.

title: A video based observation and analysis method to assess human movement and behaviour in crowded areas
abstract: Human movement in the real world provides important information for developing human behaviour models and simulations. However, it is difficult to assess 'real' human behaviour since there is no established method available. As part of the AUNTSUE (Accessibility and User Needs in Transport Sustainable Urban Environments) project, this research aimed to propose a method to assess human movement and behaviour in crowded areas. The method is based on the three major steps of video recording, conceptual behavior modelling and video analysis. The focus is on individual human movement and behaviour in normal situations (panic situations are not considered) and the interactions between individuals in localized areas. Emphasis is placed on gaining knowledge of characteristics of human movement and behaviour in the real world that can be modelled in the virtual environment.

title: Assessment of work postures and movements using a video based observation method and direct technical measurements.
abstract: The aim was to study postures and movements during repetitive work using video based observations and direct technical measurements (inclinometers and goniometers) A total of 21 healthy women from a poultry processing plant volunteered. Neck flexion 20 degrees was registered during 92% of the recorded time with the observation method, while the corresponding value measured with the inclinometer was 65% Different reference positions and different measured variables apparently contributed to the differences between the methods. Mean wrist position was measured to be 0 degrees in flexion extension and 19 degrees in ulnar deviation. Differences between the methods in the registered hand positions were small. The number of repetitive movements/minute and mean power frequency (MPF) of the electrogoniometer data was significantly related, showing both variables to be relevant measures of repetitiveness. In conclusion, the observation method and the technical measurements supplemented each other well. A reduction in class categories was suggested for future observation methods.

title: Using video based observation to shape the design of a new technology
abstract: A common problem in the development of software is that the designers either overlook certain aspects of the users' situations or do not have access to them. Not all projects are plagued by this kind of oversight, but it is widespread in the development of single user systems and is compounded when we turn to systems designed to support collaborative work.
