Neste trabalho pretendemos indagar sobre qual o papel que uma metodologia do tipo PBL tem no desenvolvimento de competências pessoais dos alunos, saber se a metodologia melhora as competências pessoais dos diplomados PBL quando comparados com outros graduados, e perspectivar o papel da metodologia ao nível das competências pessoais na construção do perfil de um graduado para o terceiro milénio. Partindo de um estudo de caso de uma IES profissionalizante, recorremos à técnica da entrevista junto dos docentes e entidades empregadoras, e à técnica do questionário junto dos restantes participantes. Os resultados conseguidos com os alunos, diplomados e docentes conduzemnos a sustentar que as metodologias PBL contribuem para o desenvolvimento de competências pessoais, essencialmente ao nível da utilização de recursos e da construção do conhecimento. Mais ainda, parece-nos possível sustentar a possibilidade de inserir nas teorias existentes, a lógica do empreendedorismo, como motivada pelas metodologias PBL. Nos empregadores, detectámos uma persistente tendência em não reconhecerem a metodologia como directamente responsável por uma melhoria de competências pessoais dos diplomados, exceptuando-se uma valorização de fundamentações mais consistentes e de atitudes mais confiantes. O trabalho reflecte ainda sobre o problema da identificação de competências que assegurem as necessidades de um mercado de trabalho multifacetado baseado em estudos e resultados concretos.

The ISO norm line 9241 states some criteria for ergonomics of human system interaction. In markets with a huge variety of offers and little possibility of differentiation, providers can gain a decisive competitive advantage by user oriented interfaces. A precondition for this is that relevant information can be obtained for entrepreneurial decisions in this regard. To test how users of universal search result pages use those pages and pay attention to different elements, an eye tracking experiment with a mixed design has been developed. Twenty subjects were confronted with search engine result pages (SERPs) and were instructed to make a decision while conditions “national vs. international city” and “with vs. without miniaturized Google map” were used. Different parameters like fixation count, duration and time to first fixation were computed from the eye tracking raw data and supplemented by click rate data as well as data from questionnaires. Results of this pilot study revealed some remarkable facts like a vampire effect on miniaturized Google maps. Furthermore, Google maps did not shorten the process of decision making, Google ads were not fixated, visual attention on SERPs was influenced by position of the elements on the SERP and by the users’ familiarity with the search target. These results support the theory of Amount of Invested Mental Effort (AIME) and give providers empirical evidence to take users’ expectations into account. Furthermore, the results indicated that the task oriented goal mode of participants was a moderator for the attention spent on ads. Most important, SERPs with images attracted the viewers’ attention much longer than those without images. This unique selling proposition may lead to a distortion of competition on markets.

Visual search is an important component of our interaction with our surroundings, allowing us to successfully identify external cues that impact our spatial navigation. Previous research has established fixation duration, fixation count, saccade velocity, and saccade amplitude as important indices of visual search. We examined the Visual Efficiency Detection Index (VEDI) comprising multiple aspects of visual search performance into a single measure of global visual performance. Forty participants, 10 adults ages 22-48, and children ages 6, 8, and 10, completed tests of working memory and visual search in response to stimuli relevant to pedestrian decision making. Results indicated VEDI statistically relates to established indices of visual search in relation to their interpretability for human performance. The VEDI was also sensitive to developmental differences in visual search performance, suggesting insight to its utility in the developmental psychological literature.
