The Effectiveness of Reciprocal Peer Teaching in an EAP Class
Authors: Zhang Jie
Published: January 2023

Peer teaching refers to the process of students teaching other students and has been applied in various contexts because of its positive impact on student academic performance as well as its social and cognitive values. Yet, most research on peer teaching tends to be long-term programmes with fixed student tutors and is mostly conducted in the field of science. This research, therefore, aims to examine the effectiveness of reciprocal peer teaching in a 50-minute EAP lesson to undergraduate students in a transnational university in China. Students alter their roles to teach and be taught by their peers on provided materials. Retention of knowledge was tested after 2 weeks to investigate the effectiveness of peer teaching, and a questionnaire-based survey was conducted to gather students’ perceptions of this learning approach. Results show that peer teaching has a positive impact on student retention rate, especially for student tutors. Students’ perception of reciprocal peer teaching is mainly positive but mixed with concerns, particularly regarding unguaranteed teaching quality. Further considerations have been discussed in this regard. Future research is also recommended to expand peer teaching in other teaching contexts and combine peer teaching with other instructional methods to better facilitate learning.

Published: January 2023

Advergames represent a new advertising concept that uses internet technology to implement viral marketing campaigns. This study aimed to conduct a comparative analysis of and impact of advergames on cultural outcomes. This cross-cultural study investigated the impact of advergame on the cultural differences and similarities between the United Kingdom and Saudi Arabia. Participants from both Saudi Arabia and the United Kingdom were invited to complete a questionnaire. The sample consisted of male and female participants from all age groups. According to the findings, most of the Saudi Arabian respondents responded neutrally to considering cultural values within advergames. By contrast, the majority of the United Kingdom participants agreed that they were indifferent to the culture projected by the advergame characters. The findings also confirm the implementation of better strategies for games that consider the different cultural aspects of different countries. Notably, these findings suggest that visual familiarity can influence consumer behavior across cultures. We expect our findings to be used in future research that examines cultural outcomes in advergames.

Indigenous justice and restorative justice: exploring perceptions of convergence and divergence in British Columbia and Saskatchewan

There is a plethora of literature conflating the terms Indigenous justice and restorative justice. This collaborative action research project examined the relationship between Indigenous justice and restorative justice in British Columbia (BC) and Saskatchewan (SK), Canada. This qualitative study employed a decolonising research method. As a result, the research was overseen by a community advisory committee, composed of justice stakeholders and knowledge keepers in BC and SK. Data were collected through 26 key-informant interviews (seventeen from BC and nine from SK) and 33 focus group discussions in eight communities in BC and SK. Our findings included the definitions of restorative justice and Indigenous justice and points of convergence and divergence. This study unearthed a wide range of distinctions between Indigenous justice and restorative justice. According to some participants, ‘there’s absolutely no similarities’ between restorative justice and Indigenous justice, whereas to others restorative justice and Indigenous justice are like the ‘difference between chocolate and vanilla ice cream’. This study demonstrates the importance of dialogue between justice stakeholders and Indigenous Elders, knowledge keepers and communities to reveal the unique and important distinctions between Indigenous justice and restorative justice. This study ends with a discussion on limitations and areas for future research.

Published: January 2023

Agrometeorological variables have a major impact on crop development and yield, known as crop phenology. The phenology of chickpea under various thermal regimes was evaluated in a field experiment during the rabi season of 2019–2020 at Ishwardi, Pabna district of Bangladesh. Three chickpea cultivars (V1 = BARI Chola 5, V2 = BARI Chola 10, and V3 = BARI Chola 11) were planted under irrigation in four temperature regimes (D1 = November 5, D2 = November 20, D3 = December 5, and D4 = December 20). Early sowing on November 5 had a larger growing degree day (GDD), 2135.5 C days from sowing to harvest, and later sowing on December 20 had a lower GDD (1743.4 C days). From planting to harvest, V1 required a greater GDD (1971.5C days) while V3 required a lower GDD (1805.8 C days). Average heliothermal unit (HTU) varied from 11764.07 C day hrs (D4) to 13879.4 C day hrs (D1). Variety V1 required 13757.85°C day hrs HTU, while V2 and V3 required 13347.05°C day hrs and 11636.8 °C day hrs, respectively. The number of days needed from planting to harvest under D1, D2, D3, and D4 growing conditions were 136.3, 122.6, 118.6, and 107.4 days, respectively. Growth and yield were better for V1 and V2 under D1 settings, but they were lower under D3 conditions, while V3 was better under D2 conditions. BARI Chola 11 among the genotypes was harvested much more quickly and produced more effectively in late-sowing conditions. Physiological maturity and grain yield can be predicted with 92% and 99% accuracy, respectively, using cumulative GDD and HTU. Therefore, the study recommended that different thermal conditions and cultivars' reactions to heat utilization and economic yield have a substantial impact on chickpea cultivar yields.

2-[3-(4-Methoxy-3-methylphenyl)-3-oxoprop-1-enyl]-4H-3,1-benzoxazin-4-one 2 was synthesized by the cyclization of the respective N-acylanthranilc acid 1. The bromination of benzoxazinone 2 afforded the dibromo anthranilic acid 3, which gave N-pyrazolyl anthranilic acid 4 on treatment with hydrazine. The ethanolysis of benzoxazinone 2 with sodium ethoxide gave ethyl anthranilate derivative 5 which on treatment with amines furnished the corresponding ethyl N-substitutedanthranilate 6a-b. The aminolysis of benzoxazinone 2 with ammonium acetate, primary amines and/ or secondary amines afforded the corresponding amides 7a-c and 8a-b. The treatment of benzoxazinone 2 with 2-aminophenol and/ or o-phenylendiamine gave the corresponding 3-(benzooxazol-2-yl) propenone 9 and 3-(benzimidazol-2-yl) propenone 10, respectively. 3-Thiourido-3(4H)-quinazolinone derivative 11 was obtained on the treatment of benzoxazinone 2 with thiosemicarbazide. The reaction of the benzoxazinone 2 with hydroxylamine hydrochloride furnished the corresponding 3-hydroxy-2-isooxazoline-5-yl-4(3H)-quinazolinone 12. The synthesized compounds were screened against strains of bacteria and showed mild to moderate activity towards both gram-positive bacteria and gram-negative bacteria.

Bioremediation, is currently one of the most studied techniques for the elimination of polycyclic aromatic hydrocarbons in soils. However, in order to have a more efficient degradation process, the use of autochthonous bacteria from the contaminated region is recommended because these bacteria are adapted to the climatic and environmental conditions of the site to be remedied. The aim of this work was to isolate and characterize bacteria strains from the city of Reynosa, Mexico, with the potential to degrade naphthalene. Strain isolation was carried out whit soil samples from the shore of“La Escondida” lagoon, a former landfill of pollutants of the petrochemical industry. The isolates were subjected to the emulsion index test as a selective factor to later evaluate their effect in the drop collapse, drop displacement and naphthalene tolerance tests. Finally, sixty-two strains were identified by amplification of the 16S rRNA gene. Ten strains showed the best values in the drop collapse, oil displacement and naphthalene tolerance tests. Four strains had the best naphthalene degradation potential; Pseudomonas aeruginosa (1P2 and 5P2), Bacillus cereus (5S1) and Bacillus subtillis (P52). A degradation of naphthalene was observed in the IR spectrum and UPLC chromatogram after 12 days by 1P2 strain.

Published: January 2023

O Direito, olhando em um contexto geral, presenteia-nos com muitas escolhas em termos de definição sistemática e minuciosa. De um lado, consiste em grande número de símbolos e ideais reciprocamente conflitivos, o que o homem comum percebe quando se vê envolvido em um processo judicial. De outra parte, não deixa de ser um dos mais importantes fatores de estabilidade social, porquanto admite um cenário comum em que as inúmeras aspirações podem encontrar uma aprovação e uma ordem. (FERRAZ JÚNIOR, 1994). Já no contexto político, o Direito deve ser provido de um conjunto de regras de conduta geradas por uma valorização diante dos fatos ocorridos em contexto histórico-social. Isto porque, em um conjunto histórico político, seja, econômico, educacional, jurídico, ou outro qualquer, é sempre um conjunto de vias objetivando almejar determinados fins. Tratando-se de política do direito, esses fins socialmente desejados e por isso úteis e justas para responderem adequadamente às demandas sociais (GUSMÃO, 1997).

Published: January 2023

Trenggalek Regency is one of the regencies in the southern part of East Java Province, which its landscape strongly expresses the historical influence of ancient volcanism and tectonics. Unlike the three neighboring districts, namely Ponorogo, Pacitan, and Tulungagung, the archaeological potential related to the condition of the Trenggalek region's landscape has not been studied much. Hills and mountains with steep slopes form nearly 80% of the Trenggalek area. In the south, karst hills and coastal areas are stretch from west to east, connecting with the East Pacitan karst area on the west and the Tulungagung karst area on the east. The lowlands are only found in the central part, forming an intermontane basin with the Ngasinan River as the main river. A geoarchaeological approach is needed to explore the archaeological potential by studying the uniqueness of its landscape (history and geological formations). Through this approach, this research leads to the pilot development of a geopark based on the features and uniqueness of the Trenggalek region's natural history and its correlation with the accompanying non-geological aspects, namely the diversity of archaeological and biological sites. Initial efforts were made by finding, recording, and assessing the features and uniqueness of locations that could potentially be used as geosites. This concept combines earth, cultural and biological aspects to conserve geological heritage, enhance the local economy, and education. The analysis of each element is based on a geoarchaeological perspective through spatial data processing based on the Geographic Information System (GIS). The final result is in the form of scientific knowledge about the geoarchaeological potential of the Trenggalek area and recommendations for geopark development according to the potential level of each geosite.

This paper examines management efforts in the Bukit Kerang Kawal Darat (BKKD) site area on Bintan Island, framing sustainable development goals (SDGs). There are indications that the BKKD site has not experienced any progress in the area, even though it has been more than ten years since the local government released the land. Identification of the potential of natural, human, and cultural resources in the BKKD area is important to be projected in the 2030 SDGs study. The SDGs study on archaeological sites is considered can help focus various parts of the most realistic and measurable by synthesizing based on Cultural Heritage Law, and Cultural Advancement Law. This paper uses inductive reasoning, starting with a discussion of all data from observations, interviews, and literature studies. The data was analyzed, interpreted, and designed as a simulation scoring method of readiness to achieve SDGs until 2030. A communication strategy is needed to produce a blueprint for measurable management stages within the framework of the SDGs until 2030 after the BKKD is registered as a cultural heritage. This is a practical and theoretical contribution to the study of Archeology for sustainable development.
