Comparative Analysis of Student Learning: Technical, Methodological and Result Assessing of PISA-OECD and INVALSI-Italian Systems .
PISA is the most extensive international survey promoted by the OECD in the field of education, which measures the skills of fifteen-year-old students from more than 80 participating countries every three years. INVALSI are written tests carried out every year by all Italian students in some key moments of the school cycle, to evaluate the levels of some fundamental skills in Italian, Mathematics and English. Our comparison is made up to 2018, the last year of the PISA-OECD survey, even if INVALSI was carried out for the last edition in 2022. Our analysis focuses attention on the common part of the reference populations, which are the 15-year-old students of the 2nd class of secondary schools of II degree, where both
sources give a similar picture of the students
Continuing education for optometrists
Effective continuing professional development (CPD) has the potential to yield better health
outcomes for optometrists and their patients. A conceptual model of CPD provided a
framework to characterize CPD and its outcomes. A mixed-method approach was chosen for
this thesis. Across three studies this thesis measured optometrists’ perspectives of CPD, the
effectiveness of a specific CPD activity, and optometrists’ capability in critically appraising the
most frequently presented statistical methods in articles published in relevant ophthalmic
scientific journals.
An in-depth study of the perspectives of optometrists towards CPD via focus groups and
interviews was conducted and responses coded to the Cabana determinant framework.
Optometrists’ attitude towards CPD was modulated by their outcome expectancy, self-efficacy,
the inertia of previous practice and their desire for self-improvement. A Likert scale measure
of 46 optometrists’ attitudes towards CPD revealed positive attitudes with mean score of 72%
(Mean=20.27, SD=3.81. Range 0-28). Meanwhile, the self-efficacy of these optometrists on the
topic of Choroidal lesions was moderate (59%) or often times weak.
A quasi-randomized controlled trial comparing the online experience of an Adaptive (n=22) to
a Traditional (n=24) CPD intervention demonstrated that Traditional learners lost significantly
more knowledge at 12 weeks compared to those optometrists randomized to the Adaptive
CPD arm of the intervention (T=3, p=0.01, r=-0.52). Adaptive learning was also seen as more
fun.
The final study evaluated the alignment between the level of statistical knowledge required to
successfully appraise the ophthalmic literature and optometrists’ self-reported knowledge,
attitudes, and practices (KAP) of statistics. The most used tests were: descriptive, t-tests,
contingency tables, non-parametric tests and ANOVAs. Together these tests were present in
61% of the 358 articles audited. Optometrists demonstrated very poor knowledge of t-tests,
contingency tables, and ANOVAs (averages of <50% correct).
Overall, the findings of this mixed-method thesis indicated that optometrists have a positive
attitude to CPD and wish to maintain and expand their learning across a lifetime. CPD
specifically focused on statistics would enable more effective lifelong learning in optometrists.
Any gaps in knowledge or practice cannot be attributed to a lack of desire to learn more

An Open Source BI Approach: Concept Proof Tracking Fleet
É possível assistir nos dias de hoje, a um processo tecnológico evolutivo acentuado por toda a
parte do globo. No caso das empresas, quer as pequenas, médias ou de grandes dimensões,
estão cada vez mais dependentes dos sistemas informatizados para realizar os seus processos
de negócio, e consequentemente à geração de informação referente aos negócios e onde,
muitas das vezes, os dados não têm qualquer relacionamento entre si.
A maioria dos sistemas convencionais informáticos não são projetados para gerir e armazenar
informações estratégicas, impossibilitando assim que esta sirva de apoio como recurso
estratégico. Portanto, as decisões são tomadas com base na experiência dos administradores,
quando poderiam serem baseadas em factos históricos armazenados pelos diversos sistemas.
Genericamente, as organizações possuem muitos dados, mas na maioria dos casos extraem
pouca informação, o que é um problema em termos de mercados competitivos. Como as
organizações procuram evoluir e superar a concorrência nas tomadas de decisão, surge neste
contexto o termo Business Intelligence(BI).
A GisGeo Information Systems é uma empresa que desenvolve software baseado em SIG
(sistemas de informação geográfica) recorrendo a uma filosofia de ferramentas open-source.
O seu principal produto baseia-se na localização geográfica dos vários tipos de viaturas, na
recolha de dados, e consequentemente a sua análise (quilómetros percorridos, duração de
uma viagem entre dois pontos definidos, consumo de combustível, etc.). Neste âmbito surge o
tema deste projeto que tem objetivo de dar uma perspetiva diferente aos dados existentes,
cruzando os conceitos BI com o sistema implementado na empresa de acordo com a sua
filosofia.
Neste projeto são abordados alguns dos conceitos mais importantes adjacentes a BI como,
por exemplo, modelo dimensional, data Warehouse, o processo ETL e OLAP, seguindo a
metodologia de Ralph Kimball. São também estudadas algumas das principais ferramentas
open-source existentes no mercado, assim como quais as suas vantagens/desvantagens
relativamente entre elas.
Em conclusão, é então apresentada a solução desenvolvida de acordo com os critérios
enumerados pela empresa como prova de conceito da aplicabilidade da área Business
Intelligence ao ramo de Sistemas de informação Geográfica (SIG), recorrendo a uma
ferramenta open-source que suporte visualização dos dados através de dashboards.Nowadays it is possible to watch a sharp evolutionary process technology throughout the
globe. For businesses, whether small, medium or large, are increasingly dependent on
information systems to conduct their business processes, and hence the generation of
information regarding business and where often the data does not have any relationship
therewith.
Most conventional computer systems are not designed to manage and store strategic
information, thus making it impossible to support this as a strategic resource. Therefore,
decisions are made based on the experience of the managers, when they could be based on
historical facts stored by different systems.
Generally, organizations have a lot of data, but in most cases draw little information, which is
a problem in terms of competitive markets. As organizations seek to evolve and outperform
the competition in decision-making, it arises the term Business Intelligence (BI in this context).
The GisGeo Information Systems is IT Company which develops its own software based on GIS
(Geographic information systems) using the philosophy of open-source. Its main product is
based on the geographical location of various types of vehicles, collecting data, and
consequently its analysis (kilometres travelled, duration of a trip between two set points, fuel
consumption, etc.). The theme of this project arises in this context, which has aimed to give a
different perspective to the existing data, crossing the BI concepts with the system
implemented in the company according to its philosophy.
In this project the adjacent BI concepts such as dimensional model, data warehouse, ET Land
OLAP process, following the methodology of Ralph Kimball are generally addressed. Some of
the main open-source tools are also studied on the market, as well as their
advantages/disadvantages in relation to one another.
In conclusion, a solution developed in accordance with the criteria listed by the company, is
presented as proof of concept of the applicability of the Business Intelligence at the branch
GIS, drawing on an open-source support data visualization tool through dashboards
