The tasks required in this context include, for example,“reading” instructions from graphical displays in user interfaces; utilizing digital reproduction to create new, meaningful materials from existing ones; constructing knowledge from a nonlinear, hypertextual navigation, evaluating the quality ...
Campanian-Maastrichtian carbonate and marl successions in Israel are rich in organic matter (OM) ... more Campanian-Maastrichtian carbonate and marl successions in Israel are rich in organic matter (OM) of marine algal origin. Samples from these sections, which were originally processed for nannofossil study by standard techniques, were found to be almost completely devoid of nannofossils. However, removal of the OM by approximately 10 hours of controlled bleaching with sodium hypochlorite (household bleach) yielded extremely rich and diverse nannofossil assemblages. It is suggested that, by selectively bleaching the OM, calcareous nannofossils which were incorporated within the intricate organic debris were released. The fact that, after bleaching, both abundance and species diversity were clearly increased, and the preservation of the nannofossils had not changed significantly, suggests that the bleaching agent did not 'attack' the nannofloras and did not produce a biased assemblage. The proposed preparation method enables rich and diverse calcareous nannofossil assemblages to be recovered from samples which would have provided poor, or even barren, assemblages with the deployment of standard processing

Besides the group of vessels typical of sites in Judea, there are vessels characteristic of sites in southern coastal plain, and a small group whose origins may be traced to Edom, Egypt and the kingdom of Israel. The group of vessels with coastal characteristics was found in Beersheba in large quantities as an integral and typical part ...

The rationale was threefold: (a) this age group is not singled out in other surveys; (b) examination of gaming across five platforms would contribute new insights; and (c) the premise that a comparison between eGamers in a war zone and a peaceful country would produce striking contrasts. Virtually all participants played digital games for an average of 10-12 hours per week, the majority using all gaming platforms daily. Notable country differences were identified, particularly game genre preferences but there was also commonality as digital gamers. Digital games remain “boys’ games”, with males devoting more time to playing across five game platforms than did the females who, however, demonstrated a narrowing gap. Isolation and unfitness due to digital gaming proved contrary to pop...

That is, text, which was designed to be read from paper, is read online, and vice versa. This study investigated the effect of incongruent reading conditions on critical reading. A group of 80 11th graders were asked to read news items in congruent and in incongruent reading situations. Results show a negative effect of incongruent reading, in which text is converted from one display to another without adjustment. The effect was strongest for reading from a computer screen text that was designed to be read in print. Findings demonstrate the importance of format-specific text design, and suggest that universities, information repositories and other text providers should consider format adjustments in making their texts accessible for readers.

The present study aimed to generalize the ethical dissonance index (EDI), which was established in a sample of Israeli school students as the gap between the pervasiveness of academic dishonesty and its perceived legitimacy. Furthermore, the study examined how technology, dishonesty type and individual differences affect these factors. The study employed a scenario‐based approach – an indirect strategy for deducing academic dishonest behaviors. Participants were 1055 school students from various grade levels, geographic locations and religious/ethnic sectors. Results regarding the role of technology revealed that, overall, digital academic dishonesty was less pervasive and deemed more legitimate compared to analog dishonesty. However, this relationship varied as a function of dishonesty type. Findings confirmed that students experienced some level of ethical dissonance, generalizing the EDI. Notably, individual differences did not affect the relationship between media, dishonesty type and the EDI. [ABSTRACT FROM AUTHOR]

Its superiority over online learning, which lacks face-to-face interaction, is evident from studies that examined both student achievement and satisfaction. Nevertheless, there is ambiguity in the literature and in the field regarding the proper implementation of blended learning and the optimal proportions between online and F2F components in various learning scenarios. The range of contradictory reports in recent literature on the potential of different blended learning models shows the need for more research on specific blended learning courses in order to establish proper standards for effective course design and implementation. The present evaluation study focuses on students’ perceptions of pedagogical and design issues related to a new model for blended learning that was used in a graduate-level course at the Open ...
