Introduction: Sustainable development in education requires not only a variety of teaching strategies but also more demands on the education of students. This study conducted quantitative research based on the combination of the three peer-to peer principles of cooperative learning in positive interdependence, promotive interaction and individual a...

Microplastics are tiny pieces of plastic that result from the breakdown of larger plastic objects, such as water bottles, shopping bags, food containers, and many other types of waste. Microplastics can be as small as a bacterial cell or as big as a grain of rice. Microplastics exist in many different shapes: some are round and smooth while others...

Even though hydrodynamic conditions play an important role in shallow costal ecosystems such as enhancing primary production by the remobilization of nutrients, they could represent a potential threat to motile benthic animals because they can dislodge them and restrict their movements, thereby impacting their distribution within the ecosystem. Sea...

Cooperative learning in physical education not only promotes the overall development of students, but also lays the foundation for lifelong learning and sustainable development from the perspectives of cultural integration and social responsibility. This study examined students’ physical, social, emotional, and cognitive outcomes on the one hand. O...

Microplastic particles (MP) are emerging pollutants ubiquitously distributed in all aquatic environments, remaining in suspension in the water column or deposited in sediment beds. MP are suspended in the water column along with other particles with whom they might interact. The current study presents the results of slow-settling MP (Polystyrene) s...

Microplastic particles (MP) are an emerging contaminant threatening many aquatic systems. Because of the sharp increase in plastic manufacture, the concentration of MP in natural ecosystems has grown dramatically. While it is known that when MP enter aquatic ecosystems they are transported and dispersed via different mechanisms (currents, waves, tu...

Habitat degradation in coastal ecosystems has resulted in the fragmentation of coastal aquatic vegetation and compromised their role in supplying essential ecological services such as trapping sediment or sequestering carbon. Fragmentation has changed seagrass architecture by decreasing the density of the canopy or engendering small patches of vege...

Seagrass canopies are coastal ecosystems that are able to modify the abiotic environment through their architectural structure. They have different structural parameters, such as plant stem stiffness, patch length and canopy density, all of which determine their overall functionality in modifying the seafloor hydrodynamics within coastal areas. To...

This study investigates cooperative learning educational approaches that support preservice teachers’ (PSTs) academic and social attitudes.

Socio-emotional education is referred to as the missing part that links academic knowledge to successes in school, family, community, workplace, and life. Socio-emotional education, in conjunction with academic instruction, aims to lay the groundwork for a sound moral education. This manuscript is aimed at proving that socio-emotional education may...

Dams and impoundments constructed in rivers produce changes in their hydrological and sediment transport regimes, regulate their flows and reduce the supply of sediments downstream. Artificially inducing floods from reservoirs in conjunction with sediment-replenishment strategies is currently being employed to enhance sediment supply to river catch...

Plastic debris has been found to be ubiquitous in many aquatic ecosystems and is constantly accumulating, not only because more and more plastic is being rapidly released into the environment, but also because its slow degradation means it persists in the water. Some more buoyant plastics accumulate in the water column, whereas other heavier types...

This paper describes a quantitative study that explores both the degree of preservice teachers’ (PSTs) motivation and achievement, and the dimensions of need-supportive teaching, when PSTs were involved in designing and implementing contextualized physical cooperative challenges (CPCCs) in primary schools. The analysis was based on the PSTs’ percep...

Although seagrass canopies are known to enhance particle sedimentation, there is still limited knowledge about how seagrasses modify the vertical distribution of sediment particles; especially when particles come from allochthonous sources. This study determined the volume of particles trapped by the seagrass leaves, the amount that remains in susp...

For the past two centuries coastal zones have been suffering seagrass loss resulting in a network of vegetated patches which are barely interconnected and which may compromise the ecological services provided by the canopy. To optimize management efforts for successful restoration strategies, questions need to be addressed about what appropriate ca...

In the face of today’s global challenges, the practice and theory of contemporary education inevitably focuses on developing the competences that help individuals to find meaningfulness in their societal and professional life, to understand the impact of local actions on global processes and to enable them to solve real-life problems [...]

Lagoons interspersed within wetlands are expected to increase the residence time of the flow in the system which, in turn, will lead to enhanced pollutant removal thus ensuring a good ecological status of the ecosystem. In this study, lagoons interspersed in vegetated wetlands have been mimicked in the laboratory to develop a theoretical model to e...

Nature-based wastewater treatments are an economic and sustainable alternative to intensive technologies in rural areas, although their efficiency needs to be improved.

Sustainable development is promoted when the system of education provides the learners with an opportunity to equip themselves with moral values, skills, and competences that assist them in effecting personal and community positive changes. For this purpose, teachers play an important role as moral agents, and students consider the teacher a role m...

Aquatic plants, turbulence and sediment fluxes interact with each other in a complex, non-linear fashion. While most studies have considered turbulence as being generated primarily by mean flow, it can, however, also be generated by the action of the wind or by the night cooling convection at the surface of the water column. Here, we study turbulen...

To acquire knowledge about student-mediated peer-to-peer collaborative activities, pre-service teachers’ perceptions of peer feedback are analyzed and categorized as receiver, provider, or cognitive feedback.

The combination of the filtration capacity of zooplankton (e.g. Daphnia) with the nutrient removal capacity of bacterial/algal biofilm in a zooplankton-containing reactor could provide a natural-based alternative for wastewater treatment. A laboratory-scale zooplankton-based reactor was tested at different HRTs resulting in a significant reduction...

Daphnia populations are present in lakes and ponds. They are known to experience diurnal vertical migrations according to their feeding needs. During the day they migrate downwards to avoid predation in light-receiving layers and at night they migrate upwards, searching for food in the shallow productive layers. The light photoperiod and light inte...

We study the relative importance of the three dimensions of need-supportive teaching (NST) and students’ self-efficacy to gain new knowledge about students’ achievement in higher education. NST assumes that teachers are key to the motivation of students, providing autonomy support, structure (support of competence), and involvement (support of rela...

There is consensus on the need to study the potential impact microplastics (MP) have on freshwater planktonic organisms. It is not yet fully understood how MP enter the aquatic food web or the effect they have on all the trophic levels. As a result of the potential for MP to accumulate throughout food webs, there is increasing interest in evaluatin...

Daphnia are important to understanding the biogeochemistry of aquatic ecosystems, mainly because of their ability to filter bacteria, algae and inorganic particles as well. Although there are many studies on the general effects that biotic and abiotic stressors, increased temperature and hypoxia, salinity, metals, pharmaceuticals, pesticides, etc.,...

Canopy fragmentation increases both spatial heterogeneity and patch edges which, in turn, is then likely to modify the local hydrodynamics in the canopy. The orientation of the edge versus the wave and current field is also expected to play an important role in determining wave attenuation and sheltering at the edge of a canopy. We investigated the...
