Title: Validity evidence based on internal structure of a pilot scientific literacy assessment instrument Authors: Coppi, Marcelo; Fialho, Isabel; Cid, Marília Abstract: This study presents the validity evidence based on internal structure gathered from the application of a pilot instrument to assess the scientific literacy of students at the end of the 3rd cycle of basic education. The instrument, composed of the subtestsnature of science, impact of science and technology on society and content of science, was applied to 176 students in the 10th grade from eight Portuguese schools. Evidence was gatheredusing the Item Response Theory information function.The analysis revealed that the three subtests show evidence of validity based on internal structure that makes it possible to use the results for decision making. Nevertheless, it was found to be necessary to revise the items of the content of science subtest in order forthem to better fit the characteristics of the sample

Title: Uso de suportes digitais em tarefas académicas. Um estudo com estudantes do ensino superior Authors: Monroy García, Angélica; Fialho, Isabel Abstract: El uso creciente de las Tecnologías de la Información y la Comunicación (TIC), en las más diversas dimensiones e instituciones de la vida social, impone desafíos a los sistemas educativos que deben acompañar este avance tecnológico. El objetivo de esta investigación fue conocer el uso que los estudiantes de la Universidad de Évora hacen de los soportes tecnológicos (ordenador y/o tablet y teléfono móvil), tanto en el ámbito académico como personal. La muestra de estudio está compuesta por un total de 308 estudiantes a los que se les aplicó el cuestionario CUTIC sobre los comportamientos digitales y opiniones sobre el uso de las TIC. La recogida de datos se realizó mediante Google Form, previo consentimiento informado. De acuerdo con los resultados, los estudiantes hacen un uso frecuente del ordenador y la tablet en sus tareas académicas, siendo menos frecuente el uso del teléfono móvil, mientras que sus emociones y conductas no se ven alteradas por el uso y acceso a los soportes tecnológicos en ninguno de los dos niveles de estudios analizados (grados y posgrados).

Title: Development and validation of the loneliness and solitude scale (LSS) Authors: Chiodelli, Roberto; Iacob, Vivien; Andretta, Ilana; Russell, Tamara; de Mello, Luana; Viseu, João; Antunes, João; Jesus, Saúl Neves Abstract: This study sought to develop the Loneliness and Solitude Scale (LSS) a scale intended to assess and differentiate loneliness and solitude. The loneliness dimension analyses how often an individual perceives being on their own as negative, unsatisfactory, and distressful; the solitude dimension refers to the frequency with which someone interprets their solitary moment as something positive, valuable, and pleasing. The collected sample for this research was comprised of 724 Portuguese speakers’ adults, demonstrating adequate psychometric indicators. Exploratory and confirmatory factor analysis showed the two dimensions, as expected. The results also indicate that the levels of Loneliness and Solitude are not dependent on gender, academic background, and age. In addition, the associations between the two factors of the LSS and emotion regulation, depression, anxiety, and stress corroborate previous literature findings. Cluster analysis allowed for further analysis, showing that stress, when controlling for emotional regulation, seems to have a weak effect on loneliness, a fact that is under some dispute in the current literature. This paper was able to develop and validate a unique measure of loneliness and solitude, centered around the unique characteristics of how individuals make use of their time spent alone. Future studies should attempt to compare this measure with other similar scales.

Title: Scientific literacy assessment instruments: a systematic literature review Authors: Coppi, Marcelo; Fialho, Isabel; Cid, Marília Abstract: The study aimed to analyze scientific literacy assessment instruments. In this sense, a systematic literature review was carried out in the B-On, SciELO, Scholar Google, and RCAAP databases to identify studies using scientific literacy assessment instruments. The selection criteria included articles published between 1990 and 2020 in Portuguese, English, or Spanish, which developed and/or used scientific literacy assessment instruments. Articles that did not address scientific literacy in the title or abstract did not cite instruments and results of assessing students' scientific literacy, reviews, case studies, and articles that assessed specific subjects or subjects were excluded. Thirteen scientific literacy assessment instruments were identified. Most of the studies were conducted in Brazil, Indonesia, and the United States, predominating with Secondary School students. Higher Education students were the ones with the most positive results. The most evaluated dimensions of scientific literacy were related to different scientific literacy skills. The respondents’ classifications were obtained through the descriptive frequencies of responses to the items, with no standardization in the categorization processes of the results. Our findings led us to conclude that caution is required when comparing the results of the studies, since many instruments were applied at educational levels and in contexts different from those for which they were developed.
