A Systems Perspective on Practicum Experiences in Early Childhood Teacher Education: Focus on Interprofessional Relationships

High quality early childhood teachers have a wealth of knowledge and use a range of skills in their daily classroom practices, and research has consistently demonstrated the positive influence effective early childhood teachers have on children’s development and long-term outcomes. Given the importance of practicum experiences in the development of effective teachers, exploration and understanding of these experiences for early childhood teacher candidates is warranted. The relationship between the cooperating teacher and teacher candidate can be viewed as a central element in the experience; this relationship influences and is influenced by additional elements within the practicum experience, including: communication, beliefs, fit, knowledge and learning. In this article, each of these elements is explored, and the interrelatedness of the elements within the practicum experience is discussed. A systems perspective is used to describe the multiple elements of the practicum experiences in early childhood teacher preparation programs, not only to explore the practicum experience, but also to develop recommendations and a research agenda.     

Are teachers techno-optimists or techno-pessimists? A pilot comparative among teachers in Bolivia,Brazil, the Dominican Republic,Ecuador, Finland,Poland, Turkey,and Uruguay

The aim of the article is to highlight the key elements related to the implementation of new technologies in education from the perspective of the opinions and experiences of educators in the field in Bolivia, Brazil, the Dominican Republic, Ecuador, Finland, Poland, Turkey, and Uruguay. The text compares issues related to attitudes towards the use of new media in education, experiences with different forms of e-learning, and the level of restrictions on the use of smartphones in school. These variables are juxtaposed with the self-assessment of digital competence and how cyberspace is used. The survey was conducted using a standardised survey questionnaire translated into the relevant national languages in the first half of 2019, and involved a sample of 873 teachers representing eight countries. On the basis of the pilot studies it was noted that: 1) Teachers from LAC and EU like to use digital media - this is a constant trend independent of geographical location; 2) Teachers note that new technologies are not always better than analogue didactic aids; 3) Teachers from selected countries (the Dominican Republic, Brazil, Turkey, and Uruguay) have much greater techno-optimism in themselves than teachers from Bolivia, Poland, Finland and Turkey in terms of the impact of ICT on student motivation and engagement; 4) In all countries teachers prefer free online courses (the different forms of e-learning are used most often by those in the Dominican Republic, and the least often in Bolivia and Poland); 5) In each country teachers who highly value their own digital competences and have a positive attitude towards new media use ICT much more actively; 6) There is also a global trend in that the extensive use of cyberspace (typical e-services) appears in combination with the extensive use of various forms of e-learning; 7) Teachers from Ecuador are most likely to want to ban the use of smartphones in schools. The most liberal approach in this respect is taken by the Uruguayans; 8) The knowledge of the conditions related to restricting the use of smartphones goes beyond the analyses related to the style of use and attitude towards new media. This article is the result of pilot studies conducted within the framework of the SMART ECOSYSTEM FOR LEARNING AND INCLUSION project carried out in selected Latin American, Caribbean (LAC) and European (EU) countries.

     

Massed and spaced training build up different components of long-term habituation in the crabChasmagnathus

The crabChasmagnathus granulatus reacts to a shadow passing overhead with an escape response that habituates after 30 trials and for 5 days at least. The effect of a wide range of different intertrial intervals (ITIs) (0, 9, 27, 45, 81, 135, and 171 sec) on theChasmagnathus long-term habituation (LTH) was evaluated at 24 h. Memory retention was estimated separately at two phases of a six-trial testing session: at first trial (the initial testing phase) and at the subsequent block of five trials (the retraining phase). A training of 30 trials with an ITI equal to or longer than 27 sec induced LTH at both testing phases, however, with a 0- or a 9-sec ITI, training wholly failed to build up LTH. When the number of trials was increased, a massed training (ITI=0 or 9 sec) induced LTH at retraining but not at initial testing. Thus, massed training produces LTH only at retraining, whereas spaced training (ITI ≥ 27 sec) produces LTH at both initial phase and retraining. An ITI shift from training to testing diminished or abolished retention at retraining regardless of the direction of the shift, thus suggesting that crabs acquire a memory of the trial-spacing at training. According to these results, it is postulated that LTH consists of two memory components: one produced by spaced training and expressed at both initial testing and retraining, and one yielded by massed training and expressed only at retraining. The possibility that the two components of LTH were differentially affected by cycloxemide and context shift is discussed.     

Parent role questionnaire: Psychometric qualities

The Parent Role Questionnaire (PRQ) is a recently developed instrument to study individual perceptions of the parent role. The PRQ was piloted, revised, and studied psychometrically. This study examines PRQ internal consistency, test-retest reliability, and validity. Results reveal that the instrument has relatively high internal consistency, moderate test-retest reliability, and high validity. The discussion includes implications for further research and study on parents, parenting, and the parent role.     

The improvement in walking speed induced by resistance training is associated with increased muscular strength but not skeletal muscle mass in older women

Objective: The purpose of the present study was to analyze whether improvements in fast walking speed induced by resistance training (RT) are associated with changes in body composition, muscle quality, and muscular strength in older women. Methods: Twenty-three healthy older women (69.6?±?6.4 years, 64.95?±?12.9?kg, 1.55?±?0.07?m, 27.06?±?4.6?kg/m²) performed a RT program for 8 weeks consisting of 8 exercises for the whole body, 3 sets of 10–15 repetitions maximum, 3 times a week. Anthropometric, body composition (fat-free mass [FFM], skeletal muscle mass [SMM], legs lean soft tissue [LLST], fat mass), knee extension muscular strength (KE1RM), muscle quality index (MQI [KE1RM/LLST]), and 10-meter walking test (10-MWT) were performed before and after the intervention. Results: Significant (P?<?.05) changes were observed from pre- to post-training for FFM (+1.6%), MQI (+7.2%), SMM (+2.4%), LLST (+1.8%), KE1RM (+8.6%), fat mass (?1.4%), and time to perform 10-MWT (?3.7%). The percentage change in 10-MWT was significantly associated with percentage change in MQI (r?=??0.46, P?=?.04) and KE1RM (r?=??0.45, P?=?.04), however not associated percentage of changes in SMM (r?=?0.01, P?=?.97), LLST (r?=??0.22, P?=?.33), and body fat (r?=?0.10, P?=?.66). Conclusion: We conclude that the improvement in the 10-MWT after an 8-week RT program is associated with increases in lower limb muscular strength and muscle quality, but not with muscle mass or body fat changes in older women.     

A patent portfolio assessment of a Brazilian research university: The case of Universidade Federal Fluminense

Intellectual Property Rights (IPRs) are widely acknowledged to be of central importance to research universities worldwide. This article assesses the patent portfolio of Universidade Federal Fluminense (UFF), which is located in State of Rio de Janeiro in Brazil and currently consists of the largest Brazilian research university in terms of the total number of enrolled undergraduate students. More specifically, this study provides robust empirical evidence pointing out that a major university in a developing country is strengthening its patent portfolio by increasing the number of patent applications. In addition, it was also possible to observe that UFF's patent portfolio is dominated by emerging technologies addressing human necessities, such as medical, hygiene, or veterinary products.     

Knowledge management and scientific knowledge generation

This paper focuses on the knowledge generation property of science, asking the question how the historical success of science in the field of knowledge generation can be articulated to make it relevant to all approaches used for scientific knowledge generation in a pluralist reality. It proposes that science can be described more appropriately as a capability rather than to describe it methodologically and also provides preliminary indications on how to go about describing science as a capability. The goal of the investigation is to add value to the third generation of knowledge management where knowledge generation becomes important, not only knowledge diffusion. It assumes that knowledge generation is of foundational importance in practical problem solving.     

Through the fingers: Use of plastinated anatomical specimens for visually impaired students

The plastination technique produces non-toxic human tissues, ensuring their safe handling in educational settings. This investigation aimed to understand if visually impaired students profit from the use of plastinated anatomical specimens in learning the anatomy of the nervous system. For this purpose, their learning performance was compared to sighted and blindfolded students recruited from three primary schools in Fortaleza city, in the state of Ceará. Initially, a questionnaire was applied before carrying out the pedagogical practice, followed by an anatomy lecture with practical components with the use of plastinated anatomical specimens and synthetic anatomical models of the nervous system. After these steps, the students answered the questionnaire previously applied. Our results showed that the tactile perception of the visually impaired participants was significantly more developed compared to sighted (p < 0.001) and the blindfolded (p < 0.0001) students. The average of correct answers in the reapplied questionnaire was higher in the groups that used plastinated specimens (p < 0.05). In conclusion, the use of plastinated specimens has proven to be an effective tool in promoting a better understanding of anatomical structures, mainly for students with or without visual impairments, making it a valuable asset in anatomy teaching.     

Investigating Parent and Professional Perspectives Concerning Special Education Services for Preschool Latino Children

Population changes in the US have created new challenges for service providers responsible for screening, determining eligibility, and providing appropriate educational services to young English Language Learners (ELLs). Six focus groups (two each) with administrators, teachers, and parents were conducted in two different locations to investigate the referral, diagnostic evaluation, and placement of prekindergarten Latino children who are ELLs and their families. The purpose of this study was to: (a) identify effective practices that differentiate between cultural/linguistic differences and learning differences; (b) identify the gaps in the current special education services; and (c) make recommendations to reduce the disproportionate representation of young ELL children based on these data. The results revealed a number of factors contributing to the disproportionality of young ELL children in special services such as: inconsistent screening and evaluation methods; insufficient numbers of bilingual professionals and trained interpreters; communication barriers and contradictory procedures that undermine meaningful partnerships with parents of ELLs; the need for professional development on the purposes and administration procedures of screening and evaluation tools; and a need for policy and regulation changes pertaining to ELL children such as the timing of screenings and evaluations.
