Gaining ‘Raw Insider Knowledge’: The Benefits and Challenges of International Study Tours for Creative Industries Students

International short‐term study tours are a fast‐growing format for outbound education and provide exciting experiential learning opportunities for students in the creative industries disciplines. This success has encouraged researchers to seek a comprehensive view of the various concrete experiences that contribute to student learning during study tours. To that end, this article presents evidence from a qualitative online post‐tour questionnaire administered with students studying various art and design disciplines who participated in short‐term international study tours at a large Australian university in 2015. Using Kolb's Experiential Learning Theory as a framework, data collected explored student perceptions of which concrete experiences on a study tour are most impactful and which may actually hinder learning. Findings revealed: experiencing key industry venues are the most significant aspects of a study tour, rather than networking or personal growth; poor itinerary planning and travel issues are the least liked aspects of a tour, yet are often the most easily addressed with better tour management and planning; and students were positively impacted by unexpected gains in knowledge about their creative industries discipline. This study, therefore, provides unique insights into which concrete experiences may be most impactful as part of the experiential learning cycle within an international study tour for creative industries students.     

A numerical analysis to the non-linear fin problem

In this paper a numerical analysis is carried out to obtain the temperature distribution within a single fin. It is assumed that the heat transfer coefficient depends on the temperature. The complete highly non-linear problem is solved numerically and the variations of both, dimensionless surface temperature and dimensionless surface temperature gradient as well as heat transfer characteristics with the governing non-dimensional parameters of the problem are graphed and tabulated.     

Educational Interventions to Improve Dental Anatomy Carving Ability of Dental Students: A Systematic Review

This systematic review aimed to identify the level of impact of educational strategies for teaching tooth carving on the carving ability of undergraduate dental students. The PubMed-NCBI, Cochrane-CENTRAL, LILACS, Ibecs, BBO, Web of Science, and Scopus databases were searched in May 2019, for randomized controlled trials (RCTs) and two-arm non-randomized studies of interventions (NRSI) addressing educational interventions toward the dental carving of undergraduate students. Studies from the year 2000 until the search date, written in English, Portuguese, and Spanish were included. Study screening and data extraction were performed in duplicate and blinded. The data were presented narratively, considering the dental carving ability of students the primary outcome. The risk of bias was assessed using the RoB tool 2.0 and ROBINS-I, and the level of evidence was determined with GRADE. Of 3,574 studies, 6 were included, with 3 RCTs and 3 NRSIs. Very low level of evidence was provided from the NRSIs that flipped classroom (1 study; n = 140) and a student-driven revised module (1 study; n = 264) improved the carving ability of students. Additionally, there was moderate evidence of online complementary material (1 RCT; n = 30) and reinforcement class improving the carving ability of students (1 RCT; n = 29). The replacement of traditional classes by an instructional DVD (1 RCT; n = 73) and assessment of carving projects through digital systems (1 NRSI; n = 79) did not enhance the carving ability of students. Study design, risk of bias, and imprecision downgraded the level of evidence. There was a very low to moderate evidence on the effectiveness of student-driven educational approaches and complementary classes of dental anatomy in improving the dental carving ability of students.     

Adaptive control of printing devices using fractional-order hold circuits adjusted through neural networks

A connectionist method for autotuning the free parameter of a fractional-order hold (FROH) circuit in order to improve the performance of the digitally controlled systems is proposed. Such a technique employs multilayer perceptrons to approximate the mapping between the sampling period/continuous-time parameters of the estimated plant and the optimal value of the FROH adjustable gain. In this way, adaptive discretization systems to improve the stability properties of the resulting discrete-time zeros are implemented. Simulation results are presented in order to illustrate the properties of the complete system applied to two actual digitally controlled printing devices (HP 7090A and low-cost computer printer).     

The impact of bilingual preschool education on the language development of Spanish-speaking children

This study addressed the question of what effect bilingual preschool education has on the Spanish and English language development of Spanish speaking children. This question was addressed by measuring the language proficiency of children enrolled in a bilingual preschool program and children who stay at home during the day. Three dimensions of language proficiency were examined: language reception, production, and verbal complexity. Using a repeated measures design, it was found that children enrolled in preschool gained proficiency in English at a faster rate while maintaining a similar level of Spanish proficiency as those children who stay at home during the day. Results of this study are discussed in terms of current issues in the early childhood education of non-English-speaking children.     

Pedagogical differences during a science and language intervention for English language learners

The purpose of this study was to compare and describe 8 fifth-grade classrooms by their teachers pedagogy during a quasiexperimental, longitudinal, and field-based project focused on increasing English language learners' (ELLs') achievement in science and language. The larger study found statistically significant and positive intervention effects in favor of the treatment group on measures of science and language achievement. This study adds an in-depth analysis of the teacher pedagogical practices contributing to students' science and language achievement as captured by an observational instrument used during the project. Results from the analysis show how treatment teachers, when compared to control teachers, focused on activities promoting verbal and written interaction among the students and dense cognitive language use during science inquiry instruction. The findings support the importance of effectively using language in the science classroom to improve ELLs' science and language achievement. Implications for future research and practice are discussed.     

The Integration of English Language Development and Science Instruction in Elementary Classrooms

This paper explores one district’s attempt to implement a blended science and English Language Development (ELD) elementary program, designed to provide English language learners opportunities to develop proficiency in English through participation in inquiry-based science. This process resulted in blended program that utilized a combined science/ELD lesson plan format to structure and guide teachers’ efforts to use science as the context for language development. Data, collected throughout the first 2 years of the program, include teacher-generated lesson plans, observation notes, and interviews with teachers and principals. The process by which the blended program was developed, the initial implementation of the program, the resulting science/ELD lesson plan format, and teachers’ perceptions about the program and its impact on their students are described.

Effect of Dental Course Cycle on Anatomical Knowledge and Dental Carving Ability of Dental Students

This study assessed the effect of the course cycle on theoretical knowledge of dental morphology and the dental carving ability of dental students. Thirty-two dental students from the third semester (initial cycle) and 30 students from the eighth and tenth semesters of the dental course (end cycle) had their theoretical knowledge on dental morphology assessed using a questionnaire with ten closed questions. Their dental carving ability was also assessed using wax carvings in macro models of plaster (for the third [S3] and eight [S8] semesters) and natural-sized artificial teeth (for the tenth [S10] semester). The teeth chosen for the dental carving activity were #16 and #47. The scores were statistically analyzed using the t-test, Kruskal–Wallis test, and Mann–Whitney test (α = 0.05). Students from the initial cycle presented better theoretical knowledge than the other groups did (P < 0.007). No significant differences in carving score were found between the initial and end cycles (P > 0.05), although S10 students obtained a higher score for teeth #16 and #47 (P < 0.05). Natural-sized artificial teeth received a higher evaluation score in dental carvings than the macro models (P < 0.001). Within the limits of this study, it was possible to conclude that students from the initial cycle (S3) presented higher theoretical knowledge, whereas no difference in carving ability was observed between the initial and end cycles. The tenth semester (S10) students performed dental carvings with better quality. Furthermore, carvings in natural-sized artificial teeth presented better quality compared with the macro models.     

Spanish Teachers' Epistemological and Scientific Conceptions: Implications for teacher education1

We present the theoretical framework, the central issues, bibliographic antecedents, and most relevant results of three studies concerning Spanish teachers' epistemological and scientific conceptions. The samples analysed present a majority tendency towards an absolutist view of knowledge and an empiricist conception of science. In our view, this represents a real obstacle to constructive and active professional development. Finally, we argue the need for an epistemological education of teachers that is closely linked to the design and development of the school curriculum, and that does not reproduce the traditional academicist-type models.
