This study investigated the effects of first language (L1) congruency, second language (L2) proficiency, and the collocate-node relationship (i.e., verb-noun, adjective-noun, noun-noun) on collocation processing by logographic L1-Chinese learners of English. Comparisons were made of accuracy rates and response times to a collocation lexical decision task completed by L1-Chinese English as a Foreign Language (EFL) English Majors (n = 30), L1-Chinese EFL non-English Majors (n = 30), and L1-English Native Speakers (n = 26). Analysis of the data revealed that while congruent collocations were processed more accurately and faster than incongruent collocations by both L1-Chinese participant groups, the English Majors showed a processing advantage over their non-English Major peers. Further analysis revealed a processing advantage for noun-noun collocations, providing additional evidence in explaining the difficulties L1-Chinese have in acquiring verb-noun collocations. These results and other nuanced statistical findings are discussed in relation to pedagogical means of enhancing L2 collocation acquisition by L1-Chinese speakers.

Hydrogen sulfide (H2S) is a gaseous signaling molecule that plays multiple roles in plant development. However, whether endogenous H2S plays a role in fruit ripening in tomato is still unknown. In this study, we show that the H2S-producing enzyme l-cysteine desulfhydrase SlLCD1 localizes to the nucleus. By constructing mutated forms of SlLCD1, we show that the amino acid residue K24 of SlLCD1 is the key amino acid that determines nuclear localization. Silencing of SlLCD1 by TRV-SlLCD1 accelerated fruit ripening and reduced H2S production compared with the control. A SlLCD1 gene-edited mutant obtained through CRISPR/Cas9 modification displayed a slightly dwarfed phenotype and accelerated fruit ripening. This mutant also showed increased cysteine content and produced less H2S, suggesting a role of SlLCD1 in H2S generation. Chlorophyll degradation and carotenoid accumulation were enhanced in the SlLCD1 mutant. Other ripening-related genes that play roles in chlorophyll degradation, carotenoid biosynthesis, cell wall degradation, ethylene biosynthesis, and the ethylene signaling pathway were enhanced at the transcriptional level in the lcd1 mutant. Total RNA was sequenced from unripe tomato fruit treated with exogenous H2S, and transcriptome analysis showed that ripening-related gene expression was suppressed. Based on the results for a SlLCD1 gene-edited mutant and exogenous H2S application, we propose that the nuclear-localized cysteine desulfhydrase SlLCD1 is required for endogenous H2S generation and participates in the regulation of tomato fruit ripening.

Language teacher beliefs have received increasing research attention for the past few decades. However, little is known about the beliefs of pre-service teachers in the pre-primary English as a foreign language (EFL) education context. This qualitative case study extends this line of inquiry by investigating the trajectory of student teachers' beliefs about teaching English to pre-primary learners in Macau within a teacher education course. The participants included 60 pre-service teachers taking an English Language Activities course in their third year of a 4-year Bachelor of pre-primary education program. The data comprised written reflections collected at three points in time during the 16-week course: at the beginning of the course, mid-way through the course, and at the end of the course. The findings showed five broad themes, constituted from 15 subthemes, regarding (1) learners and learning, (2) teaching, (3) subject, (4) self, and (5) learning to teach. The major themes have been documented in the literature, but several subthemes were identified for the first time in the context of pre-primary EFL teacher education. More importantly, the findings revealed that some of the subthemes were newly shaped and several subthemes were reshaped as a consequence of taking the course. The findings were interpreted in relation to the content of the course, the experiential learning opportunities, the pre-service teachers' prior experiences of language learning and teaching, and the local language teaching and learning context. Implications for pre-service teacher education programs are discussed.

Research on the beliefs of pre-service and in-service English teachers at the primary, secondary, and tertiary levels has provided useful knowledge to teacher education curriculum designers. However, the beliefs of pre-service pre-primary English as a foreign language (EFL) teachers have not been addressed. Thus, a case study was conducted in one pre-primary education program at a public university in the Macau Special Administrative Region of China. Data was collected by providing participants ( N = 63) a writing prompt aimed at gathering their beliefs about the teaching and learning of English in the pre-primary context. Qualitative content analysis was used to analyze these written reflection reports of third-year pre-service pre-primary English teachers with the aim of uncovering their beliefs about teaching and learning EFL. Results showed the participants held beliefs about classroom practice, EFL learners and learning, pedagogical knowledge, teaching, content, goals of language teaching, the role of teaching, subject, schooling, hearsay, self, learning to teach, and the teacher education program. Most participants mentioned their beliefs about classroom practice, EFL learners and learning, and pedagogical knowledge, while very few participants wrote about self, learning to teach, or the teacher education program. While many of the beliefs held by the participants were found to be substantiated by early childhood education research, some unfounded beliefs were also uncovered. The results highlighted a need for curriculum designers to reconsider the education program’s ability to meet the needs of the pre-service teachers. Participants required additional training in English content knowledge, use as a medium of instruction, and pronunciation. The polarized view of teaching the mother tongue and EFL should be reconsidered in light of the current views on bilingualism and bilingual education.

The global importance of English and therefore the teaching of the English language has made the English language curriculum an integral part of all levels of teacher education, including early childhood education. The purpose of this study was to first explore the beliefs about the teaching of English to very young learners held by pre-service pre-primary teachers in Macau and then to see whether these beliefs were reflected in their microteaching. Qualitative content analysis performed on the written reflections and transcriptions of the microteaching videos of 75 pre-service pre-primary teachers found that their beliefs about classroom practices, lesson planning, and English as a foreign language (EFL) learners and learning were the most predominant beliefs exhibited in their reflections and were evidenced in their microteaching. Less predominant, but still salient, were their beliefs about the goals of language learning, assessment, teaching, pedagogical knowledge, and content. No observable practices were found regarding the pre-service teachers’ beliefs about the role of teaching, learning to teach, microteaching, the self, the subject, hearsay, self-assessment, and schooling. The current study found that with only limited exposure to EFL teaching methodology from a single course, the pre-service pre-primary teachers were able to implement some of their beliefs about several important aspects of teaching English to very young learners.
