“…In this study it was observed that performances in practical courses are higher compared with performances in theoretical courses irrespective of subjects. It has been found that practical work effect overall students' academic attainment in science [39]. Further, practical work improves students' attitudes and motivation on learning in science [40,41].…”

Aims: Academic performances of undergraduate students may depend on many factors. Researches in literature have taken different factors into consideration and these effects may vary depending on different aspects such as place, period and group. This study aimed to identify effects of course related factors on academic performances, which are linked with design of courses. As the course related factors, subject of course, type of course (theoretical, practical), volume of course (number of credits), and level of course (year of study) were considered. Place and Duration of Study: This study was carried out at Faculty of Science, Eastern University, Sri Lanka with the undergraduate courses in the science stream and results of students in a batch completed the degree recently. Methodology: A group of all students in a batch that recently passed out from the faculty was used as the sample and there were 109 students. Data including gender, stream of study, subject of course, type of course (theoretical/practical), volume of course in terms of numbers of credits, levels of courses were gathered as the factors and grades of courses was taken as the measure that represents academic performances of students. Grades were transformed to grade point values and then it was used as the main response. Analysis was carried out with both parametric and nonparametric statistical approaches. Results: It could be revealed that academic performances of undergraduates depend on course related factors tested. Performances tend to decrease with the increase in number of credits of the course meanwhile higher performances could be observed in practical courses compared with theory based courses. Irrespective of other factors, performances for courses in the third year of study were higher than that of courses in other years of studies. Conclusion: Academic performances of undergraduates are dependent on these factors related to courses. However, it needs further work to generalize the results.

“…Knowledge on energy production and expenditure and its modulation by internal and external factors is crucial for veterinarians and hence already implemented within the undergraduate curriculum of veterinary medicine. During lectures basic information and important notes on this topic are provided to second years students, but deep and sustainable understanding is often only reached when students get the chance to learn in the form of a "hands on" practical class as multiple studies demonstrated (1)(2)(3)(4)(5). The planning and conduction of those practical courses are often challenging due to the limited time available for these sessions.…”

In endothermic mammals total energy expenditure (EE) is composed of basal metabolic rate (BMR), energy spent for muscle activity, thermoregulation, any kind of production (such as milk, meat or egg production) and the thermic effect of feeding. The BMR is predominantly determined by body mass and the surface to volume ratio of the body. The EE can be quantified either by direct or indirect calorimetry. Direct calorimetry measures the rate of heat loss from the body, whereas indirect calorimetry measures oxygen consumption and carbon dioxide production and calculates heat production from oxidative nutrient combustion. A deep and sustainable understanding of EE in animals is crucial for veterinarians in order to properly calculate and evaluate feed rations, during special circumstances such as anaesthesia or in situations with increased energy demands as commonly seen in high yielding livestock. The practical class described in this manuscript provides an experimental approach to understand how EE can be measured and calculated by indirect calorimetry. Two important factors that affect the EE of animals (the thermic effect of feeding and the effect of ambient temperature) are measured. A profound knowledge about the energy requirements of animal life and its measurement is also relevant for education in general biology, animal and human physiology and nutrition. Therefore, this teaching unit can equally well be implemented in other areas of life sciences.

“…Bevins and Price (2016) suggest that inquiry is the best method for teaching science; promoting research skills in students and helping them internalise new knowledge in the search for answers to scientific questions. This type of methodology has been widely used in recent years to offer numerous benefits for student learning, and to achieve a greater degree of student involvement and motivation (Couso, Sshana & Abulibdeh, 2020). However, it is also necessary to highlight that in order for this process to generate significant benefits for students, the teacher must plan, articulate and guide the student inquiry, since, as has been widely demonstrated, the best learning results are obtained when a teacher acquires the role of counsellor and activator of the student's ability to think and reason (Alfieri, Brooks, Aldrich & Tenenbaum, 2011;Furtak et al, 2012;Lazonder & Harmsen, 2016;Minner, Levy & Century, 2010).…”

This article presents an educational experience with 30 high school students based on the flipped classroom methodology and inquiry-based learning on aspects related to the pathophysiology of the digestive system during the 2017/2018 academic year. The main goal of this study was to investigate the effectiveness and acceptability of the flipped classroom approach at this educational level. This case study was also used to assess the level of inquiry competence that high school students present when they have to carry out a research project and the main difficulties encountered in carrying it out. The results of the study show that the experience was clearly positive, since there was not only a significant improvement in student learning but also greater autonomy for students to work with the content, prepare for classes and actively participate in the tasks or practical activities that take place in the classroom, demonstrating its applicability in high school classrooms. The results also indicate that the students perceived advantages in their learning after experiencing the flipped classroom pedagogical model. Most of the students presented serious difficulties in carrying out their research work, probably due to a lack of experience when facing each of the stages that make up the process of inquiry.
