Introduction Empirical data on the effectiveness of BRM trainings is still sparse and as far as studies were published, not very encouraging. Both O’Connor (2011) and Röttger, Vetter & Kowalski (2016) report that a classroom-based BRM training adopted from CRM in aviation had no effect on performance, behavior (Röttger et al.) or even knowledge and attitudes (O’Connor) of training participants. Both studies conclude that the BRM trainings under study did not sufficiently take the specific training needs of bridge teams into account, but relied too much on contents and methods from CRM trainings in aviation. The purpose of the study reported here was to assess the effectiveness of a simulator-based BRM module specifically designed to improve teamwork behavior in navigation. Method The BRM module started with a two-hour lecture on non-technical (NTS) skills with emphasize on exchanging relevant information. A one-hour simulator exercise was provided for practice of NTS during navigation. Subsequently, a detailed debriefing was conducted with feedback on the NTS that had been introduced before the simulator run. Total duration of the module was 4 hours. Fourteen bridge teams (72 sailors) served as control group and received standard nautical simulator training. Ten teams (54 sailors) were in the experimental group and received the BRM module. Differences between control group and experimental group were assessed on four levels of training evaluation as proposed by Kirkpatrick (1979): Participants’ reactions to the training, cognitive effects in terms of attitude changes (assessed with the SMAQGN, Röttger, Vetter & Kowalski, 2012), behavior as observed in the frequencies (utterances per minute) of information exchange regarding level 1 situation awareness (e.g. readings of instruments or sightings of other vessel) and of level 2 situation awareness (SA) as defined by Endsley (1995), and performance in the detection and avoidance of an upcoming collision during a simulator run subsequent to the BRM training module. Results Reactions regarding global evaluation as well as organization and presentation of the simulator training did not differ between groups, but the traditional training was found to be of higher interest and relevance (3.8 vs. 4.1 on a five-point Likert-scale, p<.01). No attitude differences were found between groups at the end of the simulator training. Within-subject comparisons of ship management attitudes were performed with one-sided t-tests for dependent samples, based on the assumption that the training would have a positive or no effect, but not a negative effect on attitudes. Attitude change was found in the experimental group, but not in the control group. Attitudes were more positive towards communication and coordination after as compared to before the simulator training (4.0 vs. 4.1, p<.01). Due to the distinct non-normal distribution of the behavior frequency data, medians instead of arithmetic means are used to report central tendencies, and significance of group differences was assessed with Wilcoxon-Mann-Whitney tests. As for attitudes, effects of the BRM module in the direction opposite to the training aims were deemed unlikely and one-sided tests were performed. Sharing level 1 SA information was very similar in both groups (every 103 vs. 100 seconds, p=.45). Communications on situation assessments or command aims were observed every 5.5 minutes in the experimental group, but only every 9 minutes in the control group. With p=.06, this difference narrowly missed statistical significance. Teams who avoided a collision with or without a last-minute maneuver are distributed equally between control group and experimental group. Collisions, however, occurred in the control group only. Pearson's χ2 test was performed to examine this difference. Based on the frequency distribution, it tests the null hypothesis that all safety outcomes have equal probabilities in both groups. With χ2 = 3.43, p = .056, statistical significance is again narrowly missed. Discussion The effects found in this study are rather small, and the observed differences between experimental group and control group in behavior and performance fell just short of the standard limit of α ≤ .05 for statistical significance. This can be explained by the limited scale of the BRM module, which lasted only four hours and comprised only one cycle of instruction, exercise, and feedback. Due to the consistent pattern of results, we argue that this data can be regarded as an indication of the effectiveness of a simulator-based BRM training. When comparing the results reported here with those described in Röttger et al. (2016), we find it remarkable that four hours of BRM training in a simulator have a stronger effect on behavior and performance than five days of BRM training in the classroom. If the instructions on non-technical skills is scheduled at the beginning of simulator trainings, and feedback on the non-technical skills will be provided together with nautical feedback at the end of each simulator run over the course of 2 – 4 days of training, we expect larger effects on behavior and performance of the sailors than those we could find in this study.

Abstract The objective of this work was to assess whether the implementation of a bridge resource management (BRM) unit into the simulator-based nautical training of the German Navy is effective in improving non-technical skills and navigation performance. To this end, questionnaire data, observations of behaviour and performance outcomes were compared between a control group and an experimental group. Data of 24 bridge teams (126 sailors) were used for the analyses. Ten teams received BRM training and 14 teams served as the control group with unchanged simulator training. Reactions to simulator training were positive in both groups but more favourable in the control group. In the BRM group, significantly more positive attitudes towards open communication and coordination, more frequent sharing of information and fewer collisions were found than in the control group. Effect sizes were rather small. This may be due to the limited scale of the BRM unit, which consisted of only one instruction-training-feedback cycle. The extension of BRM-related feedback to all simulator runs of the nautical training can be expected to produce larger effects on attitudes, behaviour and performance.

Purpose This research applies a quasi-experimental research method to investigate the impact of an innovative resource titled “Accounting Exercise” (teaching intervention using physical movement and lyrics) on learning motivation and performance on a group of students enrolled in a first-year undergraduate accounting course in Japan. Design/methodology/approach Five classes were randomly assigned to either an experimental group (two classes) or a control group (three classes). In the experimental group, 90 students participated in a 15-min “Accounting Exercise” at the commencement of lectures over three consecutive weeks. The remaining 133 students assigned to the control group did not participate in the Accounting Exercise. Findings The findings indicate that the Accounting Exercise provided stimuli in maintaining students’ learning motivation. This finding is important for entry-level students where learning motivation has the potential to influence students’ future decisions on major areas of study and career choices. Originality/value This finding is important for entry-level students where future career options are decided. This effect is also believed to contribute to reducing the declining numbers of students in accounting majors.

We examined whether or not instructing Taiwanese students in the use of comprehension strategies when they are reading English as a foreign language, reduces their English reading anxiety and increases their English reading self-efficacy and proficiency. We used a quasiexperimental design and conducted a 15-week course. The experimental group (n = 31) received instruction in reading comprehension strategies and the control group (n = 31) received instruction by traditional teaching methods. The results show that the experimental group had less anxiety when reading English and higher proficiency than the control group. In regard to self-efficacy when reading English, the experimental group also performed better than the control group in terms of self-affirmation, perseverance, verbal persuasion, and performance overall. However, there was no statistically significant difference for learning attitude between the groups.

Abstract the aim of our study was to evaluate influence of probiotic agents (Lactovita) and seaweed extracts (Biopolym) with antidiarrheal effects on the prevention of diarrhoea in calves. In the experiment 22 experimental and 22 control calves were observed. The results of the observed incidence of diarrhoea in the control and experimental groups showed a positive effect of probiotic Lactovita and seaweed extracts Biopolymer. 32% of calves in the experimental group and 45% of calves in the control group became sick. Unfortunately, we could not demonstrate the statistical significance of these differences. The weight gains found in the 4th week after birth were by 37.6% higher in the group with Lactovita and Biopolym than in the control group.

The study aims at evaluating health-generating function of humor therapy in a hospital ward hosting children suffering from respiratory pathologies. The main scope of this study is to investigate possible positive effects of the presence of a clown on both the clinical evolution of the on-going disease, and on some physiological and pain parameters. Forty-three children with respiratory pathologies participated in the study: 21 of them belonged to the experimental group (EG) and 22 children to the control group (CG). During their hospitalization, the children of the EG interacted with two clowns who were experienced in the field of pediatric intervention. All participants were evaluated with respect to clinical progress and to a series of physiological and pain measures both before and after the clown interaction. When compared with the CG, EG children showed an earlier disappearance of the pathological symptoms. Moreover, the interaction of the clown with the children led to a statistically significant lowering of diastolic blood pressure, respiratory frequency and temperature in the EG as compared with the control group. The other two parameters of systolic pressure and heart frequency yielded results in the same direction, without reaching statistical significance. A similar health-inducing effect of clown presence was observed on pain parameters, both by self evaluation and assessment by nurses. Taken together, our data indicate that the presence of clowns in the ward has a possible health-inducing effect. Thus, humor can be seen as an easy-to-use, inexpensive and natural therapeutic modality to be used within different therapeutic settings.

Purpose: There is need to focus on extensive use of technology in teaching and learning process, since the teachers are provided with well-organized WebQuests that are beneficial for developing effective teaching skills. The study aims to investigate the extent of the effects of WebQuests on the teaching skills and performance of pre-service teachers of English at the College of Education of King Khalid University. Methodology: The study sample, which included 35 students of the general diploma in English, were divided into two groups: experimental and control. The members of the control group were supervised in the traditional way during their teaching practice, and the members of the experimental group were given WebQuests so that they could surf the internet under the guidance of their supervisor and find the information they needed about teaching skills. The teaching performance of the teachers of both groups was assessed via a teaching performance observation form. The data collected through classroom observation was analyzed using SPSS. The differences between the teachers of both the groups in terms of the teaching skills were calculated using Mann-Whitney U test. Findings: Statistically significant differences were found in the rank means of the participants of the control and the experimental groups regarding their lesson planning and teaching skills. The results were favorable for the teachers of the experimental group; however, no significant difference was found between the scores of the experimental and the control groups in terms of lesson evaluation skills. Originality: The use of WebQuests significantly enhances the teaching skills of the students of the general diploma in English.

This research attempted to explore the effects of divergent and convergent tasks on the successful reading of EFL students at the preparatory stage. To verify the analysis, the null hypothesis was established that states "There are no differences of statistical significance at the level of (0,05) among the mean of scores of the experimental group who study according to divergent and convergent task technique and the mean of the scores of the control group who study according to the regular method".  The experimental approach is used by designing two equivalent experimental groups of 32 students studying the technique proposed, and an 8-week (2019-2020) control group of 32 students, three classes each week using the Google Classroom Platform and Telegram. The present study utilized the platform Google Classroom (GC) and Telegram as an educational platform to assist students during their course learning process. The writing skills test was administered after checking with the experts. The results show that there are statistical differences at level (0,05) between the average of the experimental and control groups' reading skills and those of the experimental group. This difference is because the experimental group uses divergent and convergent tasks.

Abstract Introduction. The main purpose of this study was to evaluate the effect of a training programme aimed to enhance toe-toboard consistency on footfall variability and performance in the long jump. Material and methods. The study involved 36 male physical education students. The experimental group participated in a 12-week training programme, whereas the control group was limited to taking part in the classes held at university. All participants performed 6 long jump trials during two testing sessions. The kinematic parameters were assessed using the Optojump Next device and were further analysed to determine the variability of footfall placement during the approach run. Results. The analysis revealed a significant (p < 0.01) decrease in footfall variability in the experimental group between the pre-test and post-test. After the completion of the training programme, the participants significantly (p < 0.05) improved their take-off accuracy. Additionally, they significantly (p < 0.05) increased their velocity in the last five steps before take-off and the effective distance of the jump (p < 0.001). Conclusions. The results of this study indicate that through specific training, it is possible to improve the consistency of the steps in the acceleration phase of the approach run in the long jump. Moreover, decreasing footfall variability helps achieve a more stable step pattern which may be beneficial for greater accuracy at the take-off board and makes it possible to increase step velocity at the final stage of the approach run.
