Results of a Student Survey on the State of Digital Transformation in Austrian Secondary Colleges for Agriculture and Forestry (HBLAs)- Juniper Publishers

Agricultural Research & Technology: Open Access Journal

Introduction

At the HLBAs the digital transformation is already in full swing. It means the transition from analogue to digital teaching, away from paper and pencil to the keyboard, mouse and touchscreen. Digital devices and media are more and more used in teaching the learning content. This can increase motivation and collaboration in the classroom, in class preparation, in project work, in homework, and in exam study, and also improve learning outcomes. But the place and time of learning also change from being bound to a classroom to a virtual, independent learning. Digital devices and media determine the lessons. For the students, digital learning becomes interesting because of digital devices, e.g. PC (standalone unit). A more accurate shows that in the classroom with a daily and weekly use so far Beamer (92%), Internet (91%), PC as stand-alone unit (80%) as well as Whiteboards / Smartboards (46%) arrived. In contrast, cell phones, smartphones (33%) and learning platforms (34%) play a lesser role. Notebooks are used by a third. Almost half (48%) of the students use learning software, online quizzes and tests. Also, digital media are used for communication. At school, 80% of learners use email, followed by WhatsApp (63%) and the class folder (53%).

Which Risks are Moving?

The students’ responses express a clear awareness of the risks associated with the use of digital devices and media. The students see more and more online risks that unsettle them in the Internet use. The topics of data security and data protection have a high priority. The majority of students do not believe in the security of data on the Internet. Currently, 70% of respondents believe that their data is uncertain. In this context, with increasing digital transformation, data protection also becomes a challenge for HBLAs. For many students, the unauthorized disclosure of their data and the threat of viruses and malicious programs as well as the spying of their data is the greatest risk of Internet use. Surpris -ingly, the traditional media, such as radio, television and newspapers, are rated rather positively by the students overall.

Digital Lessons between Expectations and Wishes

Another result of the survey was not surprising, 57% of the students advocate increased use of digital media in the classroom. Learners would like to see the use of digital media in learning and teaching, especially where it makes sense. One of the reasons for this is that digital media can make teaching more diverse and interesting (87%). Also, regarding a future job, they see the integration of digital know-how in the classroom as necessary preparation (70%). In addition, 70% of students believe that digital media should be used more widely, i.e. teachers should try something new more often. In this regard, 63% of students agree that teachers are well prepared to use digital media for teaching. On the other hand, half (49%) of learners emphasize that teachers should be more interested in using digital media. Furthermore, the digital transformation of teaching also presents a challenge to teachers who should use digital devices and media authentically and meaningfully. The survey results also show that 78% of students agree that the teaching materials should be available digitally. According to the answers, the learners also believe that a transcript is valuable and useful and that the use of the board should not be neglected.

The Mixture makes it

The main finding of this survey is that the majority (80%) still favor a mixture of analogue and digital forms of learning. Thus, in many classrooms, the blackboard and textbooks are still the linchpin of the time-bound instruction. Nevertheless, half of the students still hope that in the future learning will take place more and more in virtual spaces. Digital devices and media are tools to make not only learning, but also teaching more student-friendly, diverse and modern. Another important outcome of this survey was that the students see in the digital transformation a way to improve their current learning model both inside and outside the school. For example, every fourth student uses social media and blogs for homework and lesson preparation outside class hours

These Challenges are Brought about

The digital transformation at the HBLAs is seen as a central task by the school management and policy makers. The learners respond to this challenge in different ways: on the one hand, there are the digital enthusiasts who really invest time until digital excellence and, on the other, those who hardly or only moderately care and feel motivated. This is also reflected in the learners’ assessment of their knowledge: 62% of students say they have a basic digital knowledge, 34% have user proficiency and 4% expert knowledge. Also, according to the subjective assessment of the students almost two-thirds of teachers have a positive attitude towards digital media
One of the strengths of digital transformation is undoubtedly that teaching materials can be exchanged quickly and easily. In addition, multimedia, interactivity and the possibility of networking and communication extend the possibilities of teaching and learning independently of time and place. To ensure this, however, the technical requirements must be met. According to the proportion of students, it becomes clear that one in two (52%) points to the lack of professional support and maintenance of the technology
Digital transformation at the HBLAs is often understood to merely exchange pencil, paper and books for computers, notebooks or smartphones. However, this assessment fails to recognize that this change requires pedagogy adapted to digital education. The learners at the HBLAs, in turn, are challenged to deal with the digital transformation in order to use it to their advantage. This should lead young people to a responsible use of digital devices and media.

The Digital School Life is already a Reality

The students have already settled in the digital school life. They realize the potential and opportunities of digital learning but are also aware of its risks. Digital devices and media can be a useful tool for individual support of students and enrich the everyday school life at the HBLAs. As a result, students can be better promoted in their individual learning process and encouraged to become more responsible and self-reflective. Digital devices and media, modern pedagogical concepts and accompanying teacher training should be linked in such a way that the learners at the HBLAs can be guaranteed an optimal learning environment. The fact is: The HBLAs as a learning and educational institution prepare students for life in society and a professional activity. The future depends on promoting the potential and talents of the students. Digital competence plays a key role here. A society in technological change needs changing HBLAs. Current pedagogical patterns of action must also be measured against the new social requirements of the digital transformation
This article is based on select results of the study ‘Digital transformation in Austrian secondary colleges for agriculture and forestry’[1]. The aim of the study was to present the current state of digital transformation at the HBLAs and to explain the further need for action. You can find this study on the homepage of the Federal Institute of Agricultural Economics, Rural and Mountain Research. It was commissioned by the Federal Ministry of Sustainability and Tourism and coordinated by Pres. 4, Schools, Teaching and Research Centers. Special thanks go to the students who have taken the time to participate in the survey and to all those who contributed to the success of this study.

Phyto-Tissue Culture Bank (PTCB) for Maintaining Plant Diversity-Juniper Publishers

Agricultural Research & Technology: Open Access Journal

The diversity of life forms is many, and we still have to define many of them as they form a complex biological fabric entangled of life on this planet. Plant biodiversity is very fantastic form of life forms which serves the humanity happiness. However, many forms of plant life are deteriorating and extinct for many reasons, including urbanization that does not take into account plant life in the construction sites and the construction of roads as well as the unfair harvesting of many of these plants which are important in many industries and grassing without having a new place for culture, which causes the extinction. In addition to changing the climatic conditions which play unfair role in changing the plant growing behaviour that cause the deterioration of plant diversity in its natural site [1-3].
Plant biodiversity must be dealt with all the more earnestly as a worldwide wealth, to be filed, utilized, conserved and safeguarded as true to type to the original plant source from which is taken. Traditional plant propagation techniques known to farmers are used to conserve ex situ vegetation diversity, but these methods face many barriers to natural propagation, making them unsuitable for plant conservation in a timely manner and in limited space, especially those plants that suffer from immature seeds as well as seeds and buds dormancy, non-seed or few seeds produced and also exposure to unfavorable climatic conditions or exposure to insects and pathological injuries during the propagation time.
It is known that, plant wild types form important part of plant biodiversity on the earth especially those plants that used in development of fodder plants, pharmaceuticals and many industries. Such wilds are going to be endangered and must be safeguarded.
For this purpose, the welfare solution is to use the technique of cultivating cells and tissues in the process of propagation and conservation of this plant diversity as in vitro botanical garden [4,5]. In this respect, there are near 100 botanical gardens throughout the world have the tissue culture and micropropagation facilities [4,6]. However, more than 400 botanical gardens throughout the world are banks of seeds preservation. As with most tissue culture systems, any plant part can be maintained and multiplied to shootlets and plantlets as true to type as most in culture by dividing and sub-culturing on appropriate fresh medium periodically under controlled aseptic conditions.
Reproduction of plants in vitro is really important for safeguard plant wilds from annihilation [7,8]. In vitro methods can set substitutional procedures for reproduction and preserving the plant assets in the long term for these species forming Phyto-Tissue Culture Bank (PTCB). In vitro propagation can provide plant stocks not only in identical forms but also certified free of pathogens of those species around the year [9-11].
Moreover, if available enough plants produced in vitro, they can be used to regenerate the existent populates for establishing novel implantations for preservation, research, education, or recreation purposes. In vitro produced plants can be marketed to compilers and that will decrease the unfair harvesting pressures on wild plants [12].
It is remarkable that, there is an acquired action worldwide for using phyto-tissue culture techniques for reproduction and conservation of endangered plants in response to the Global Strategy for Plant Conservation (GPSC) [13]. Therefore, Phyto-Tissue Culture Bank (PTCB) can be utilized for long when seeds or embryo banking is not possible or when conventional propagation is not useful for ex situ embalmment, furthermore, (PTCB) provides plant materials for agrarian various researches, plant cultivation in fields for minifies compressing on collecting the wild plants in nature; taxonomic, methodological, identification and confirmation research; sorts preface and recovery of habitats activities; confirmed varieties for nursery trade, local agriculture, safe agriculture, local forests, and crop breeding programs and demonstration, learning, teaching and society effectivenesses.
It is concluded from the above that, the need to use in vitro tissue culture techniques is a necessary necessity to maintain plant assets, giving an incentive to defeat these difficulties and making these strategies a fundamental piece of the ex situ preservation system; whereas, in vitro plants are multiplied in many folds through the multiplication process that can eventually improve and increase declining habitats of rare plant species, retrieve equalization to sensitive biological communities harmed by human and irregular impedance. It was necessary to use phytotissue culture protocols to preserve the possessed inherited plant diversity wealth from ancient times and conserve them in Phyto- Tissue Culture Bank (PTCB).
