Undergraduate Biotechnology Students’ Views of Science Communication

Despite rapid growth of the biotechnology industry worldwide, a number of public concerns about the application of biotechnology and its regulation remain. In response to these concerns, greater emphasis has been placed on promoting biotechnologists’ public engagement. As tertiary science degree programmes form the foundation of the biotechnology sector by providing a pipeline of university graduates entering into the profession, it has been proposed that formal science communication training be introduced at this early stage of career development. The aim of the present study was to examine the views of biotechnology students towards science communication and science communication training. Using an Australian biotechnology degree programme as a case study, 69 undergraduates from all three years of the programme were administered a questionnaire that asked them to rank the importance of 12 components of a biotechnology curriculum, including two science communication items. The results were compared to the responses of 274 students enrolled in other science programmes. Additional questions were provided to the second year biotechnology undergraduates and semi‐structured interviews were undertaken with 13 of these students to further examine their views of this area. The results of this study suggest that the biotechnology students surveyed do not value communication with non‐scientists nor science communication training. The implications of these findings for the reform of undergraduate biotechnology courses yet to integrate science communication training into their science curriculum are discussed.     

ARE STUDENTS PREPARED TO COMMUNICATE? A CASE STUDY OF AN AUSTRALIAN DEGREE COURSE IN BIOTECHNOLOGY

Public concerns about biotechnology have resulted in greater attention being paid to the mechanisms by which biotechnology is communicated with non-scientists, including the provision of science communication training. As undergraduate and postgraduate courses form the foundation of the biotechnology sector by providing a pipeline of university graduates entering into the profession, it has been proposed that formal science communication training be introduced at this early stage of career development. Using an Australian biotechnology degree course as a case study, this paper examines science communication training within this course and the views of past and present students towards this training. Interviews were undertaken with 22 stakeholders in the case, including undergraduate lecturers (who also supervise postgraduate research students), doctoral candidates and biotechnologists recently graduated from the course. Few of the students felt the course provided them with any form of science communication training, let alone training in how to engage non-scientists. Many were unaware of the training available to them and few of the lecturers were able to identify where communication skills are taught within the course. A previous study of this case has also shown that biotechnology undergraduates taking this course do not value communication with non-scientists. Clearly, the current state of science communication training for these students needs to be improved if they are to enter the biotechnology workforce as able civic scientists. The findings of this study may be useful for other university biotechnology courses which have yet to integrate science communication training into their curriculum.     

Effect of hand paddles and parachute on backstroke coordination and stroke parameters

Hand paddles and parachutes have been used in order to overload swimmers, and consequently increase the propulsive force generation in swimming. However, their use may affect not only kinematical parameters (average speed, stroke length and stroke rate), but also time gaps between propulsive phases, assessed through the index of coordination (IdC). The objective of this study was to assess the effects of hand paddles and parachute use, isolated or combined, on kinematical parameters and coordination. Eleven swimmers (backstroke 50-m time: 29.16 ± 1.43 s) performed four 15-m trials in a randomised order at maximal intensity: (1) without implements (FREE), (2) with hand paddles (HPD), (3) with parachute (PCH) and (4) with hand paddles plus parachute (HPD+PCH). All trials were video-recorded (60 Hz) in order to assess average speed, stroke rate, stroke length, five stroke phases and index of coordination. When average swimming speed was compared to FREE, it was lower in PCH and HPD+PCH, and higher in HPD. Stroke rate decreased in all overloaded trials compared to FREE. The use of hand paddles and parachute increased and decreased stroke length, respectively. In addition, propulsive phase duration was increased when hand paddles were used, and time gaps shifted towards zero (no time gap), especially when hand paddles were combined with parachute. It is conceivable that the combined use of hand paddles and parachute, once allowing overloading both propulsive and resistive forces, provides a specific stimulus to improve muscle strength and propulsive continuity.     

Application of functional principal component analysis in race walking: An emerging methodology

This study considered the problem of identifying and evaluating the factors of individual performance during race walking. In particular, the study explored the use of functional principal component analysis (f-PCA), a multivariate data analysis, for assessing and classifying the kinematics and kinetics of the knee joint in competitive race walkers. Seven race walkers of international and national level participated to the study. An optoelectronic system and a force platform were used to capture three-dimensional kinematics and kinetics of lower limbs during the race walking cycle. Functional principal component analysis was applied bilaterally to the sagittal knee angle and net moment data, because knee joint motion is fundamental to race walking technique. Scatterplots of principal component scores provided evidence of athletes' technical differences and asymmetries even when traditional analysis (mean ± s curves) was not effective. Principal components provided indications for race walkers' classification and identified potentially important technical differences between higher and lower skilled athletes. Therefore, f-PCA might represent a future aid for the fine analysis of sports movements, if consistently applied to performance monitoring.     

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.     

Optimizing quality of dental carving by preclinical dental students through anatomy theory reinforcement

Knowledge of dental anatomy is of great importance in the practice of dentistry, especially in oral rehabilitation, because without this knowledge, professional practice is not possible. Dental carving plays a major role in training dental students as it develops their manual dexterity. This randomized controlled trial aimed to evaluate the influence of didactic‐theoretical reinforcement on the theoretical and practical knowledge of dental anatomy of preclinical students by examining the quality of the anatomical restorations performed by these students before and after a didactic‐theoretical reinforcement. For the evaluation of theoretical knowledge, a questionnaire with closed questions about dental anatomy was used. To evaluate the effect of didactic reinforcement on dental carvings, two groups of 15 preclinical students were assessed. Experimental group (G1) received a three‐hour theoretical tutoring on dental anatomy, while the control group (G2) did not. The dental carving scores obtained by the two different groups were compared using Student's t‐test. Cohen's d was used to estimate the effect sizes between groups. The frequency of correct answers given for each theoretical knowledge question was compared in each group using Fisher's exact test. T‐test was also used to compare the means of the two groups' final scores of theoretical evaluations. To compare these final scores obtained in both carving and theoretical tests, a principal component analysis was performed with different items assessed in each test to obtain factor loading scores and a final weighted score, where factor loadings were considered for each item. Weighted scores were compared using t‐test. Also, scores obtained during the head and neck course were assessed and compared using t‐test. Spearman's correlation test was used to assess the correlation between scores obtained prior to the anatomy course and scores obtained in the dental carving exercise. The theoretical evaluation revealed no significant difference between the grades (mean ± SD) of G1 (85.1 ± 6.6%) and G2 (86.2 ± 9.1%) with the grades of a baseline test that was previously obtained when students submitted to the study (P = 0.725). Regarding the tooth carving assessment, the dental carving quality by students of G1 has significantly improved, except for tooth #23 (P = 0.096). Theoretical reinforcement of dental anatomy seems to improve the students' carving performance but does not enhance their knowledge about dental anatomy.

Effects of classroom environment on science attitudes: A cross‐cultural replication in Indonesia‡

A three‐phase study, with a different sample for each phase, involved a total of 1125 secondary school students in Indonesia. The first phase involving 373 grade 8 and 9 students was used to develop and validate an Indonesian classroom environment instrument with eight scales based on the Individualized Classroom Environment Questionnaire and the Classroom Environment Scale. In the second phase of the study, 502 Indonesian science students in grades 11 and 12 were involved in a translation, adaptation and validation of a four‐scale Indonesian version of the Test of Science‐Related Attitudes. In the third phase, these new Indonesian attitude and environment scales were used with another sample of 250 Indonesian biology students in an investigation of the effects of classroom psychosocial environment on students’ science‐related attitudes. The finding of statistically significant associations between environment and attitudes replicated much prior work in science classrooms in developed countries. For example, more favourable science‐related attitudes on several scales were found in classes perceived as having more personalization, participation, investigation and order and organization.

     

Moving forward: Inclusive education as the core of Education for All

This article attempts to shed light on what is meant by the statement that inclusive education is the core of the Education for All (EFA) agenda. Against the backdrop of some fundamental concerns relating to the EFA goals expressed by UNESCO’s Assistant Director-General for Education, the article highlights the necessity and pertinence of inclusive education within the EFA agenda. It also suggests how we can move the concept of inclusive education forward in this context, while illustrating some key features for our understanding of inclusive education as the core of EFA.
