The impact of using wordlists in the language classroom on students’ vocabulary acquisition

Vocabulary has always been an area of interest for many researchers since words represent “the building block upon which knowledge of the second language can be built” and without them people cannot convey the intended meaning (Abrudan, 2010). Nation (1988) emphasised if teachers want to help their learners to deal with unknown words, it would be better to spend more time on vocabulary learning strategies rather than spending time on individual words. However, Schmitt in Schmitt and McCarthy (1997:200) stated that among vocabulary learning strategies only ‘guessing from context’ and ‘key word method’ have been investigated in depth. Therefore, there is need for more research on vocabulary learning whose pedagogical implications may contribute to the field of second language learning. Considering the above-mentioned issues, vocabulary is a worthwhile field to investigate. Hence, this paper aims at proposing a framework for vocabulary teaching strategy in English as a foreign language context.publisher versio

Simultaneous X‐Ray Diffraction and Tomography Operando Investigation of Aluminum/Graphite Batteries

Rechargeable graphite dual‐ion batteries are extremely appealing for grid‐level stationary storage of electricity, thanks to the low‐cost and high‐performance metrics, such as high‐power density, energy efficiency, long cycling life, and good energy density. An in‐depth understanding of the anion intercalation mechanism in graphite is fundamental for the design of highly efficient systems. In this work, a comparison is presented between pyrolytic (PG) and natural (NG) graphite as positive electrode materials in rechargeable aluminum batteries, employing an ionic liquid electrolyte. The two systems are characterized by operando synchrotron energy‐dispersive X‐ray diffraction and time‐resolved computed tomography simultaneously, establishing a powerful characterization methodology, which can also be applied more in general to carbon‐based energy‐related materials. A more in‐depth insight into the AlCl4−/graphite intercalation mechanism is obtained, evidencing a mixed‐staged region in the initial phase and a two‐staged region in the second phase. Moreover, strain analysis suggests a correlation between the irreversibility of the PG electrode and the increase of the inhomogenous strain. Finally, the imaging analysis reveals the influence of graphite morphology in the electrode volume expansion upon cycling.EC/H2020/646286/EU/HIGH SPECIFIC ENERGY ALUMINIUM-ION RECHARGEABLE DECENTRALIZED ELECTRICITY GENERATION SOURCES/ALIONBMBF, 03XP0128E, ALIBATT - Al-Ionen-Batterie mit hoher volumetrischer Energiedichte für die ElektromobilitätTU Berlin, Open-Access-Mittel – 202
