Opis:
This pilot study aims to identify the presence of components which are consistent with meaningful learning in science teaching. Semi-structured interviews were conducted with six science teachers and the results show that some of the teachers’ perceptions and practices in science teaching are consistent with meaningful learning components. Science teachers’ descriptions led to the identification of six categories which can be classified into two sets of components: Constitutive (e.g., ‘authenticity’ and ‘prior knowledge’) and. Consecutive (e.g., ‘cooperative learning’, ‘knowledge construction’, ‘learning by doing’ and ‘feedback’). Based on these results, it can be concluded that there is a positive change in teachers’ perceptions and implementation of pedagogical processes for promoting meaningful learning in science teaching. The implications of these findings for future research are discussed.

Opis:
The article presents a hardware implementation of the foreground object detection algorithm PBAS (Pixel-Based Adaptive Segmenter) with a scene analysis module. A mechanism for static object detection is proposed, which is based on consecutive frame differencing. The method allows to distinguish stopped foreground objects (e.g. a car at the intersection, abandoned luggage) from false detections (so-called ghosts) using edge similarity. The improved algorithm was compared with the original version on popular test sequences from the changedetection.net dataset. The obtained results indicate that the proposed approach allows to improve the performance of the method for sequences with the stopped objects. The algorithm has been implemented and successfully verified on a hardware platform with Virtex 7 FPGA device. The PBAS segmentation, consecutive frame differencing, Sobel edge detection and advanced one-pass connected component analysis modules were designed. The system is capable of processing 50 frames with a resolution of 720×576 pixels per second.
