Mācību video lietojums skolēnu izpratnes veicināšanai matemātikas mācību satura apguvē

2016

Šajā darbā ir izpētīta teorija par video kā mācību materiāla formātu, apzināta Latvijas un pasau- les pieredze, izmantojot mācību video, un apkopota un analizēta informācija par macibuvideo.lv pieejamo mācību video lietojumu un tā atbilstību labai praksei. Praktiskās daļas būtiskākais pie- nesums ir iepriekš nekur nepublicētu datu analīze par macibuvideo.lv apmeklējumu un detalizē- tāk – par šajā vietnē pieejamo mācību video – lietojumu. Galvenais secinājums – veids, kā tiek skatīti mācību video ir ļoti dažāds, tāpēc, veidojot mācību materiālus, mēs nevaram pieņemt, ka skolēni tos redzēs no sākuma līdz beigām. Apmeklējuma dati apstiprin…

Risk of Periodontal Disease: Is there a Correlation with the Type of Antihypertensive Medication?

2011

Introduction: The purpose of this study was to evaluate the effects of long-term oral antihypertensive treatment using centrally acting sympatho-inhibitory drugs (clonidine) and beta-blockers (metoprolol) on capillary microcirculation in the labial and periodontal mucosa.
 Methods: Sixty subjects were recruited for the study: 20 patients affected by hypertension in treatment with centrally-acting sympatho-inhibitory drugs (64.28 ± 11.78 years); 20 patients in treatment with beta-blockers (62.03 ± 9.84 years) and 20 healthy subjects (62.06 ± 6.72 years). We use the videocapillaroscopic technique to evaluate in vivo the microcirculation of the labial mucosa corresponding to the lower lip…

Producing Lecture Videos from Face-to-face Teaching

2014

There is a clear demand for lecture videos in modern education. Nevertheless, the desire to keep face-to-face education remains as well. In such a case, the natural option is to produce videos in face-to-face teaching situations rather than in a studio environment. The challenge this kind of production faces is how to make it to cover an entire degree program cost-efficiently while serving the purpose intended. This article explains the demands set for video production in the context of face-to-face education at the scale of a degree program and how to effectively respond to them in practice. The paper also evaluates the effectiveness and impacts of the production model developed in connect…

Autentiskie video materiāli skolēnu klausīšanās prasmju pilnveidei angļu valodas stundās 8. klasē

2022

Diplomdarbā tiek pētīts, kā iespējams pilnveidot 8. klases skolēnu klausīšanās prasmes, izmantojot autentiskos video materiālus angļu valodas stundās. Darbs sniedz ieskatu klausīšanās prasmju nozīmē komunikācijā un autentisko video materiālu izmantošanā angļu valodas stundās. Izvēlētā pētījuma metode bija gadījuma pētījums kādā no Latvijas vidusskolām. Skolēnu aptaujas, testi, skolēnu atsauksmes un intervijas ar trīs angļu valodas skolotājām tika izmantotas kā datu ieguves metodes. Iegūtie dati liecina, ka autentisku video materiālu izmantošana angļu valodas stundās, pozitīvi ietekmē skolēnu klausīšanās prasmes: skolēniem ir vieglāk saprast dažādus akcentus, viņus mazāk ietekmē fona troksni…

Performing Authenticity on a Digital Political Stage: Politainment as Interactive Practice and (Populist?) Performance

2020

This article investigates the way politicians use social networking sites as effective communication platforms to discursively enhance authenticity, sincerity and (self-)connection to what can be defined as the “People” (followers/lurkers/net-users). Within the framework of Social Media Critical Discourse Studies, and using tools coming from Multimodal Discourse Analysis, the paper analyses the multi-semiotic elements used by different political leaders (i.e. Alexandria Ocasio-Cortez and Matteo Salvini), to connect with the “People,” and discusses the politainment product as a personalised way to skip the institutional mediation channels of politics.

Inclusive didactics and assistive technologies: the experience of a group of special needs teachers

2018

This paper describes the results of an exploratory survey aimed to examine the experience of a group of special needs teachers on the use of ICT in teaching to students with autism spectrum disorder. It is focused on the effectiveness of video modeling as a tool through which to learn (self-learning and imitation) specific skills in the field of personal autonomy. By sharing the thought of Rossi (2012), which has stated that "digital technologies provide to school an extraordinary opportunity to put on the agenda the issue of learning and, together with it, the professionalism of teachers", the authors handed out a questionnaire to a group of special needs teachers of a Comprehensive School…

Primary ciliary dyskinesia assessment by means of optical flow analysis of phase-contrast microscopy images

2014

Primary ciliary dyskinesia implies cilia with defective or total absence of motility, which may result in sinusitis, chronic bronchitis, bronchiectasis and male infertility. Diagnosis can be difficult and is based on an abnormal ciliary beat frequency (CBF) and beat pattern. In this paper, we present a method to determine CBF of isolated cells through the analysis of phase-contrast microscopy images, estimating cilia motion by means of an optical flow algorithm. After having analyzed 28 image sequences (14 with a normal beat pattern and 14 with a dyskinetic pattern), the normal group presented a CBF of 5.2 +/- 1.6 Hz, while the dyskinetic patients presented a 1.9 +/- 0.9 Hz CBF. The cutoff …
