Preschool teachers and classroom aides: Same context,similar perceptions of children's behaviors?

This study explored the correspondence and differences between school staff perceptions of preschool children's social skills and behavior problems. One hundred preschoolers were assessed by 14 pairs of teachers and classroom aides with the Preschool and Kindergarten Behavior Scales – 2^nd Edition (PKBS‐2 Portuguese version). Indexes of agreement and disagreement were calculated. Risk levels and item analyses of PKBS‐2 scores according to both informants' ratings were compared. A higher level of agreement was obtained for social skills scores than for behavior problems (mean correlation of .62). No statistically significant differences between informants were obtained for the risk levels, and item analyses revealed a similar pattern of behaviors that were most and least rated by both informants. Results indicate that the classroom aides' perspective on preschool assessment represents a reliable input, which justifies that they network with teachers in addressing preschoolers' social‐emotional and behavioral challenges.     

Students’ views of assessment in project-led engineering education: findings from a case study in Portugal

According to the demands of the Bologna process, new educational methods and strategies are needed in order to enhance student-centred learning. Project work is one of those approaches. This paper aims to evaluate the impact of project-led education (PLE) on students’ learning processes and outcomes, within the context of a first-year engineering programme. It explores students’ perceptions about assessment procedures and processes. Data collection was based on individual surveys at the end and the beginning of each PLE edition and through focus groups, after a period of six months. Findings are presented according to emerging themes from the data analysis, focusing mainly on students’ perspectives of learning and assessment, the role of formative and summative assessments in PLE and their impact on learning. Implications for improving assessment practices are discussed.     

Is accreditation ‘on the right track’? The views of Portuguese academics

In many countries, quality assurance systems rely on study programme accreditation. As with all quality assurance mechanisms, accreditation should also be continuously improved in order to maintain its relevance as a promoter of study programme quality. A way to move accreditation forward is by taking into account academics’ views, interests and needs about the process, since their support for it is paramount for its success and effectiveness. This paper analyses Portuguese academics’ knowledge and views on accreditation with the aim of understanding if the process is being supported and is on the right route for being effective. It is based on the analysis of 1484 academics’ answers to a questionnaire distributed in 16 higher education institutions. This analysis reveals a moderately positive attitude of academics towards accreditation, reflected in an only moderate knowledge of the process as well as in a mild agreement with its characteristics and implementation features. This suggests that there is room for improvement to bring this quality assurance mechanism closer to academics’ expectations and needs and therefore to improve accreditation’s effectiveness.

     

Perspectives on pedagogical change: instructor and student experiences of a newly implemented undergraduate engineering dynamics curriculum*

Engineering education has been slow to adopt research-based educational innovations. Few prior works on such adoption have investigated the combined classroom experiences of instructors and students when such innovations are being implemented. Therefore, this work focuses on the lived experiences of an instructor and her students when adopting an active, blended, and collaborative learning environment, known as Freeform, in a second-year dynamics course. Weekly reflections from the instructor were processed alongside student interviews using Thematic Analysis to discern prominent themes in their perspectives for comparison and discussion. The results indicate that the instructor navigated internal tensions between her previous instructional preferences and the philosophy and resources of Freeform. Similarly, students had to adapt to this new philosophy and suite of resources that were uncommon for their institution. Ultimately, this work highlights the contextual natures of teaching and learning, and how situational factors can influence educational innovation.

Artificial intelligence in education: evolution of the teaching—learning relationship

In this paper some of the implications of the exploitation of Artificial Intelligence techniques in the educational field are presented, and the evolution of the changing quality of interaction between student and teacher is illustrated. Such historical changes are presented as a consequence of the introduction of new technologies in education. Particular aspects of Intelligent Educational Systems are presented, pointing out the innovative features of such systems compared with traditional applications.

Elimination of lipaemic interference by high-speed centrifugation

IntroductionIn order to deliver high quality results, detection and elimination of possible analytical interferences, such as lipaemia, is crucial. The aim of this study is to evaluate the efficacy of high-speed centrifugation in eliminating lipaemic interference and to define own lipaemic index (LI) for the studied biochemical analytes.Materials and methodsEvaluated analytes were: albumin, alkaline phosphatase, alanine-aminotransferase (ALT), aspartate-aminotransferase (AST), calcium, creatinine, gamma-glutamyltransferase (GGT), glucose, phosphates, total proteins, urea and total bilirubin. Those analytes and LIs have been analysed in duplicate in the Roche Diagnostics-c8000 analyser in samples centrifuged at 3000 rpm/10 minutes in the SL16 (Thermo Scientific, Waltham, USA) centrifuge and according to an own high-speed centrifugation protocol (12,900 rpm/15 minutes) in the MicroCL17R (Thermo Scientific, Waltham, USA) centrifuge. Lipaemia has been measured in each sample. The efficiency of high-speed centrifugation is verified by the Wilcoxon test (P < 0.05). In cases where significant differences are observed, our own LI is calculated. For ALT and AST, it is verified by McNemar test (P < 0.05). For creatinine, both Wilcoxon and McNemar test were applied.ResultsThere were statistically significant differences in analyte concentration before and after high-speed centrifugation for: albumin, creatinine, GGT, glucose, phosphates, urea and total bilirrubin. Own LI is calculated. McNemar test shows statistically significant diferences in the proportion of delivered results before and after high-speed centrifugation in ALT, AST and creatinine.ConclusionsThis study confirms the efficacy of high-speed centrifugation protocol for all the considered analytes, excepting calcium, alkaline phosphatase and total proteins.
