This study sleuthed on the wide yet less explored issue called out-of-field teaching among the public junior high schools in Zamboanga City, Philippines. It focused on the extent and experiences of teachers who are assigned to teach social studies but are not licensed in it and conversely those licensed but are assigned to teach outside the field of social studies. It also sought to discuss the perceptions of some school administrators on the factors that lead to the occurrence of the phenomenon. Data were mainly gathered using a descriptive-qualitative method, particularly through survey, interviews, and document analysis. The results revealed that 37% of the teachers assigned to teach social studies is teaching out of their field of specialization. Interviews also show a consensus in identifying under-loading of teachers, lack of resources, and the lack of coordination between the HEIs and DepEd as main factors to out-of-field teaching in the city. It also suggests that out-of-field teachers experience a certain degree of emotional and physical stress and difficulty in understanding certain contents and practical concepts. These are reflected on their instructional practices that include the reliance on textbooks and the use of survival strategies such as lectures, group reports, and video presentations. This situation can be partly attributed to and/or is further exacerbated by onerous number of subject preparations and the unavailability of adequate instructional resources.    Hence, the findings of the study imply the need for higher education institutions to conduct constant assessment of actual demand for teachers among the schools in the division. Regular training programs for out-of-field teachers aided by the production of adequate instructional resources are also necessary. Lastly, a review on the policy concerning the daily number of teaching loads of the teachers is deemed necessary to minimize the extent and magnitude of out-of-field teaching.

Rapid online trading expansion and the bloom of internet technologies has raised the importance of effective product video presentations for online retailers. This article developed a model for the impacts of video presentations on purchase intention for digital and home appliance products. Four group experiments were designed, and empirical tests were performed. This research found that presenting videos on how to use digital and home appliance products increased purchase intention by raising the information gained by customers. Meanwhile, video tutorial information had insignificant effects related to the knowledge and experience of customers.

PurposeThe purpose of this paper is to examine the determinants of learners' satisfaction with a new blended learning method, namely online video presentations.Design/methodology/approachThe study tests the proposed model using responses from 353 students who were exposed to the new method. Regression analysis was used to test the hypotheses.FindingsThe results show that both the perceived social (e.g. reduction in comparison bias) and utilitarian (e.g. presentation originality) benefits increase satisfaction with the online video presentation method, from both the creator's and the learner's perspectives.Practical implicationsThis study provides several guidelines to instructors employing blended learning methods, as well as designers of platforms that enable blended learning.Originality/valueThis study provides a model to understand the determinants of learners' satisfaction with a new blended learning method. It looks at these determinants from both the content creators' perspective and the content viewer's perspective.

A central problem of behavioural studies providing artificial visual stimuli for non-human animals is to determine how subjects perceive and process these stimuli. Especially in the case of videos, it is important to ascertain that animals perceive the actual content of the images and are not just reacting to the motion cues in the presentation. In this study, we set out to investigate how dogs process life-sized videos. We aimed to find out whether dogs perceive the actual content of video images or whether they only react to the videos as a set of dynamic visual elements. For this purpose, dogs were presented with an object search task where a life-sized projected human was hiding a target object. The videos were either normally oriented or displayed upside down, and we analysed dogs’ reactions towards the projector screen after the video presentations, and their performance in the search task. Results indicated that in the case of the normally oriented videos, dogs spontaneously perceived the actual content of the images. However, the ‘Inverted’ videos were first processed as a set of unrelated visual elements, and only after some exposure to these videos did the dogs show signs of perceiving the unusual configuration of the depicted scene. Our most important conclusion was that dogs process the same type of artificial visual stimuli in different ways, depending on the familiarity of the depicted scene, and that the processing mode can change with exposure to unfamiliar stimuli.
