This study focuses on learning with the Global Change app, an interactive tool for fostering climate change knowledge. Numerous studies have contributed to the question on what type of instruction is best to achieve learning gains. The findings are mixed. We applied the app in university courses and investigated which instructional setting a discovery learning approach (no supplementary guidance) or an approach that leans more toward direct instruction is more effective (+ supplementary guidance). Thus, we distinguished between conceptual and procedural guidance within our direct instruction approach. Our study was implemented in a digital learning environment with 110 students participating in the study. We applied a 2 × 2 experimental design with different types of guidance as treatment (conceptual and procedural). An online questionnaire was administered in pretest and posttest to measure climate change knowledge as well as different variables. Our results show that the app provided gains in climate change knowledge in a short period of time regardless of treatment. Further, students who received no supplementary guidance acquired more knowledge about climate change than the groups that received supplemental guidance (either conceptual, procedural, or both). Learning gain correlated significantly negatively with cognitive load across the whole sample, but there were no significant differences between groups. This finding might be interpreted in terms of the renowned expertise reversal effect.

Impacts Of Climate Change

Abstract Rhodolith beds are important marine benthic ecosystems, representing oases of high biodiversity among sedimentary seabed environments. They are found frequently and abundantly, acting as major carbonate 'factories' and playing a key role in the biogeochemical cycling of carbonates in the South Atlantic. Rhodoliths are under threat due to global change (mainly related to ocean acidification and global warming) and local stressors, such as fishing and coastal run-off. Here, we review different aspects of the biology of these organisms, highlighting the predicted effects of global change, considering the additional impact of local stressors. Ocean acidification (OA) represents a particular threat that can reduce calcification or even promote the decalcification of these bioengineers, thus increasing the eco-physiological imbalance between calcareous and fleshy algae. OA should be considered, but this together with extreme events such as heat waves and storms, as main stressors of these ecosystems at the present time, will worsen in the future, especially if possible interactions with local stressors like coastal pollution are taken into consideration. Thus, in Brazil there is a serious need for starting monitoring programs and promote innovative experimental infrastructure in order to improve our knowledge of these rich environments, optimize management efforts and enhance the needed conservation initiatives.

Understanding climate change and revealing its future paths on a local level is a great challenge for the future. Beside the expanding sets of available climatic data, satellite images provide a valuable source of information. In our study we aimed to reveal whether satellite data are an appropriate way to identify global trends, given their shorter available time range. We used the CARPATCLIM (CC) database (1961–2010) and the MODIS NDVI images (2000–2016) and evaluated the time period covered by both (2000–2010). We performed a regression analysis between the NDVI and CC variables, and a time series analysis for the 1961–2008 and 2000–2008 periods at all data points. The results justified the belief that maximum temperature (TMAX), potential evapotranspiration and aridity all have a strong correlation with the NDVI; furthermore, the short period trend of TMAX can be described with a functional connection with its long period trend. Consequently, TMAX is an appropriate tool as an explanatory variable for NDVI spatial and temporal variance. Spatial pattern analysis revealed that with regression coefficients, macro-regions reflected topography (plains, hills and mountains), while in the case of time series regression slopes, it justified a decreasing trend from western areas (Transdanubia) to eastern ones (The Great Hungarian Plain). This is an important consideration for future agricultural and land use planning; i.e. that western areas have to allow for greater effects of climate change.

Climate change poses serious challenges to achieving food security in a time of a need to produce more food to keep up with the worlds increasing demand for food. There is an urgent need to speed up the development of new high yielding varieties with traits of adaptation and mitigation to climate change. Mathematical approaches, including ML approaches, have been used to search for such traits, leading to unprecedented results as some of the traits, including heat traits that have been long sought-for, have been found within a short period of time.

The teaching and learning process is rapidly becoming technology driven with the integration of digital learning using of online learning platforms to facilitate instructional delivery. Google classroom learning platform is one of the effective ways of enhancing student active engagement in an online learning environment. The purpose of this study is to examine the impacts of Google classroom as an online learning delivery platform in secondary school during the COVID-19 pandemic in Nigeria. A mixed method approach was used in the study. Online questionnaire on Google Classroom Attitude Scale (GCAS) was used and online Semi-Structure Interview Guide (SSIG) developed by the researcher for data collection on the students’ perceptions on Google classroom. The researcher used Statistical Package of Social Science programme to calculate and analyse arithmetic mean, standard deviation and t-test. Content analysis was used for analysis of qualitative data. The participants were 140. The results showed that Google classroom platform as an online learning delivery positively affected students' academic achievement, attitudes and their perception during the pandemic in Nigeria’s secondary school. Based on the findings of the study, it was recommended that education stakeholders should effectively prepare students for the use of this platform for their learning activities during the pandemic. The platform is capable of assisting both students and teachers to connect, work together, create assignments, grade students and post learning materials. Likewise, students can also ask questions about the areas they do not understand. Hence, the advantages of the platform can be brought into usage for achieving quality in the teaching and learning process at all levels of education during the pandemic.

Learning Log

This paper reports on the implementation of digital learning logs in the context of pre-service teacher training in a distance university in Madrid. The learning log, which had been previously implemented in the subject as a learning tool, has proven to be especially useful in Covid-19 times since the students had to work more independently and could use it to reflect upon their learning without the conventional teaching they were used to. The paper has a two-fold aim: first, to analyze whether the learning logs helped in promoting students’ autonomy and self-reflection, and second, to observe whether they contribute to the development of their linguistic competence in English as a foreign language. Participants of the study (n= 47) are students of the Primary and Infant Education degrees, specializing in English teaching, whose L2 level ranges between B1 and C2. At the end of half term, they were given the possibility of completing a learning log to record their learning process, review concepts and be aware of potential learning gaps and needs, and act accordingly. For this purpose, and to encourage participation, L1 or L2 could be chosen as vehicular languages. Participants were asked to complete an online questionnaire on their experience using the logs, answering questions regarding the suitability of this tool to enhance their language skills and promote effective strategies to become independent learners. The data drawn from the questionnaires submitted (n=29) were later analyzed through SPSS. In addition, individual semi-structured interviews were carried out to collect information on those participants who had not completed the learning log (n=11). The findings of the study show that the vast majority of participants agree on the potential of learning logs as a useful tool to keep track of their learning process and to develop metacognitive awareness and linguistic skills.

Landscape Transformations

Global change, which regroups global warming, landscape transformations and other anthropic modifications of ecosystems, has effects on populations and communities and produces modifications in the expansion area of species. While some species disappear, other ones are beneficiated by the new conditions and some of them evolve in new adapted forms or leave their ancient distribution area. As climate change tends to increase the temperature in several regions of the world, some species have been seen to leave areas in equatorial regions in order to join colder areas either towards the north of the northern hemisphere or towards the south of the southern one. Many birds as have moved geographically in direction to the poles and in many cases they have anticipated their laying dates. Actually, two tit species that use to lay their eggs in a period that their fledging dates synchronize with the emerging dates of caterpillars are now evolving to reproductive in periods earlier than before the climate change. Several species are reacting like that and other ones are moving to the north in Europe for example. Nevertheless, and very curiously, European starling, Sturnus vulgaris, populations are behaving on the contrary: their laying dates are moving towards later spring and their distribution area is moving towards the south. In this study we explore and discuss about different factors that may explain this difference from other birds.
