Comparative analyses of the Programme for International Student Assessment between immigrant and native students place immigrant students in an unfavourable position in schools, with disadvantageous indicators regarding socioeconomic and professional paths. However, the Programme for International Student Assessment assesses a series of dimensions that involve constructs that have been little studied in the school immigrant population and that relate to self-concept and school adjustment. Based on the Programme for International Student Assessment's most recent edition, Portugal's database of 7,325 15-year-old students was analysed. We selected 438 immigrant cases with two objectives: (1) to evaluate the impact of the length of exposure in the host country on three dependent variables of school adjustment: sense of belonging, perceived loneliness and attitudes towards school (expectations of educational and professional opportunities); (2) to evaluate the differences in results for the same dependent variables, but considering the first and second generation of immigrants in Portugal. For the data analysis, sampling weights and plausible values were analysed with the International Database Analyzer. The results show that students who have been in the country for a year or less have greater difficulties and increased significant differences compared to other migrant groups in the referred indices of self-concept and inclusion. However, other groups, especially those with periods of long-term residence between four and five years, also face substantial levels of school maladjustment.

In order to assess the accuracy and validity of proficiency diagnostic tests in Second Language (L2), specifically regarding the linguistic (orthographic, semantic, syntactic, lexical) and cognitive (verbal reasoning, lexical decision) components for the immigrant population in Portugal, a study of cut-off points of 6 tests was conducted. This study was motivated by the unknown tests and the gap concerning the testing and rating of individuals in L2 settings, different from English as L2. The objective was to validate and inform about new tests (and how to establish rating scores and understand the proficiency level of students) in Second Language Testing (for European Portuguese) especially concerning different psychometrics for specific skills (e.g., phonemic blending). In this way, we contribute to identify new procedures for schools and professionals about testing of cognitive functions in immigrant populations. First, we examined 108 non-native students attending Portuguese schools, aged 7-17 years, speakers of mother tongues other than Portuguese and residing in Portugal for a period not exceeding eight years. Then, series of univariate analyses, non-parametric tests and the calculation of percentiles enabled the subsequent classification of the subjects' proficiency levels: With or without proficiency. Several levels were identified. The sensitivity and specificity indexes were calculated using the Receiver Operating Characteristic (ROC) analysis to define the cut-off points for each test. The score calculation took into account the chronological age, age of immigration and gender variables. The evidence from this study suggests that all tasks are suitable to assess immigrant students. However with the ROC analysis, this assessment differs regarding degrees of proficiency between groups given the characteristics of the tasks and of the subjects. The importance of doing tests with discriminatory power of the subjects' performance to be able to intervene in the linguistic and cognitive areas with the greatest deficit is examined here.

Understanding the role of the practicum in the PI (professional identity) construction and reconstruction within a pre-service teacher is crucial, since this is a remarkable moment in their initial training. This moment provides new feelings and challenges, and it represents the transition from students (pre-service teacher) to teachers (in-service teacher). Although there are some studies about this subject, the perspective of a self-narrative of the PI construction had not been hitherto unveiled. In this paper, the authors try to capture the contributions of the practicum to the PI construction based on the analysis of the Practicum Report and the Board Diary. The confrontation with the real context of school and teaching is noticed as critical, and the importance attributed to the practicum is one of the most emphasized aspects. The pre-service teacher remarked the necessity to be able to (re)construct and (re)adapt methodologies. The idea that PI is constructed in community, to enhance the importance of group work, was also noticed. All in all, the most notorious contributes to the PI (re)construction were engaged with aspects that can only be experienced "in loco", raising new questions about the importance of the context of the practicum to the PI construction.

Heritage language speakers struggle in European classrooms with insufficient material provided for second language (SL) learning and assessment. Considering the amount of instruments and pertinent studies in English SL, immigrant students are better prepared than their peers in Romance language settings. This study investigates how factors such as age and home language can be used in the teaching environment to predict and examine the development outcomes of SL students in verbal reasoning and vocabulary tasks. One hundred and six Portuguese participants, SL learners, between 8 and 17 years old, were assessed in vocabulary frequency, verbal analogies and morphological extraction tasks. In alphabetic languages (Romance languages), immigrant students (in a SL learning situation) with a strong linguistic distance (a home language with a very different orthographic foundation) are expected to struggle in language learning in spite of being aware of strategies that can improve their skills. The storage and combination of morphemes can be a demanding task for individual speakers at different levels. Cognitive mapping is strongly based on linguistic features of L1 development. Results show that home language, not age, was a significant predictor of variation in student's outcomes. Speakers of alphasyllabary languages (Indo-Aryan languages as L1) were the poorest performers, the "linguistic distance" of their languages explaining the performance results.

The objective of this study was to identify causal relationships between the development of phonological abilities and progress in writing in preschool children. The participants were 44 children, with an average age of 5 years and 6 months, and whose writing was syllabic with phonetization. The children were divided into three groups. They were subjected to a pre-test and a post-test that were intended to evaluate both their writing and their phonological skills. In between the two tests experimental group 1 underwent a writing training program designed to lead them to produce syllabic-alphabetic/alphabetic writing, while experimental group 2 was subjected to a phonological training program designed to work on phonetic units. The third group served as a control group. The number of letters known and the level of intelligence were controlled. The children in the two experimental groups achieved results that revealed a similar degree of progress (greater than the control group) in both their writing and their phonological abilities.

To investigate the transmission of cryptosporidiosis in Portugal, Cryptosporidium hominis and Cryptosporidium parvum from HIV-infected patients, cattle, and wild ruminants were characterized by sequence analysis of the 60-kDa glycoprotein (GP60) gene. Fourteen subtypes within nine subtype families were identified, and three of the subtype families (If, IIb, and IId) were restricted or largely limited to Portugal. Parasites from cattle from various regions in Portugal and wild ruminants in Lisbon showed limited genetic heterogeneity (only two subtype families). All wild ruminants had the same subtype, which was also the predominant subtype in cattle all over Portugal and was found in nine HIV-infected patients in Lisbon. Two other C. parvum subtypes were only restricted to limited locations. In contrast, human parasites displayed 13 subtypes in nine subtype families, with most of the infections caused by parasites in Ib, IIa, IIc, and IId families. Two of the C. parvum subtype families (IIc and IIb) had only been found in humans. The high overall parasite diversity and high percentage of C. hominis infections attributable to Ib and C. parvum infections to IId represent unique characteristics of Cryptosporidium transmission in humans in Portugal.
