A learning environment.

Abstract: With the deployment of fast packet switching technology which includes Asynchronous Transfer Mode (ATM) facilities and Frame Relay (FR) capabilities, the telecommunications networks of the future will make extensive use of IP networking. These networks will extend into the desktop and conference room, and are in the process of revolutionizing the way video conferencing is achieved. This revolution will extend into the classroom and provide a dynamic conferencing capability on a global basis changing forever how distance learning is implemented. However, most organizations are not prepared to foreclose on their usage of established technologies such as point-to-point microwave, T1 trunking, and local video switching. It is in the financial best interests of the established organization either from the private sector or from the academic community to come up with a philosophy of how to deal with legacy technologies. The establishment of the North Suburban Higher Education Consortium (NSHEC) ATM network can serve as the model for resolving these concerns in a relevant and timely manner. This paper will use the NSHEC network as the working model for deriving viable alternatives for established distant learning environments.

Learners and Learning in EnvironmentalEducation: a critical review of the evidence

Abstract: Recent analyses of the ® eld of environmental education research have highlighted its rapidly expanding size and increasingly diverse nature (e.g. Hart & Nolan, 1999). This article reports on a review of a particular part of this ® eldÐ namely, recent empirical studies of learners and learning in primary or secondary school environmental education. The review focuses speci® cally on the nature and quality of the evidence generated by the work in this area. The concern with evidence is motivated by the tendency of previous reviews to focus on methodological trends more than research ® ndings. Claims have also been made that environmental education theory and research have overlooked `the children who are the subjects of environmental education’ (Payne, 1998a, p. 20). This review contends that efforts to address such shortcomings need to be informed by a thorough and grounded understanding of what studies have, and have not, been undertaken on students and learning, and what is known, and not known, from the evidence that these studies have generated.

Impact on the Virtual Learning Environment Due to COVID-19

Abstract: As a result of the global pandemic caused by COVID-19, universities have carried out teaching in a digital way, accelerating the inclusion and use of technologies in methodological adaptation. The research aims to ascertain the perception that students at the Faculty of Education Sciences of the University of Granada have regarding the pedagogical model adopted in the virtual learning environment during confinement through the second semester of the 2019–2020 academic year. The information collection method was an online questionnaire, using simple random sampling with proportional affixing 0.5, 95% confidence level and maximum permissible error of 4.7%. The results demonstrate a generalised dissatisfaction of the students, being fundamental to carry out the transition of the educational processes and training of the teaching staff. The implementation of active methodologies increases due to the virtual condition, specifically the flipped classroom methodology, but students manifest generalised dissatisfaction regarding the adequate methodological development and the involvement of professors. There is an outstanding use of e-mail and the virtual learning platform (PRADO), although they consider that they do not have the appropriate knowledge about image editors, video, computer graphics, synchronous response systems and anti-plagiarism tools. The students surveyed express that the tutoring functions, tasks and beliefs of the teaching staff in e-learning are not satisfactory.

Development of Learning Materials Oriented on Problem-Based Learning Model to Improve Students’ Mathematical Problem Solving Ability and Metacognition Ability

Abstract: This study aims to analyze the effectiveness of learning materials oriented on problem-based learning models, the improvement mathematical problem solving ability and students’ metacognition ability. Learning materials that developed are lesson plan, student book, student worksheet, mathematical problem solving ability and students’ metacognition ability test. This research is a development research by using the development model of Thiagarajan, Semmel and Semmel (1974). Valid learning materials according to experts, tested in class VII of SMP Negeri 13 Medan (seventh year junior high school). The results showed that learning materials oriented on problem-based learning met the effective criteria and improved mathematical problem solving and metacognition ability. Level students’ metacognition when problem solving met level of strategic use, aware use, and tacit use.

Developing Critical-Thinking Skills through the Collaboration of Jigsaw Model with Problem-Based Learning Model.

Abstract: This research aimed at examining the effectiveness of collaboration of Jigsaw and problem-based learning (PBL) model in developing students’ critical thinking skills. This research exerted an experimental design using pre-experimental one group pretest-posttest. The implementation of such model collaboration was carried out in SMK Batik 1 Surakarta, Central Java, Indonesia by engaging 37 accounting students of class XI. Before and after the implementation of the twomodel collaboration, the students were given the tests of critical thinking skills which were set in the same composition. The research data were in the form of pretest and posttest scores which were analyzed by examining t-test and gain score whose calculation was assisted by SPSS 23 program. The result indicated that there was a difference between the pretest score and the posttest score with the significance level of 0,000 < 0,05. The average of pretest and posttest scores respectively referred to 48,44 and 68,93. Accordingly, the implementation of collaboration of Jigsaw and problem-based learning (PBL) model was effective in developing students’ critical thinking skills. From this research finding, there was an impediment of time limitation in enacting the collaboration of the two models. This constraint happened while presenting the result of group discussion.
