Studies on Teaching Strategies for Italian Grade Test: Taking the Writing Part as an Example

This article has first introduced that Italian preparatory course training should be with language test as the teaching baton based on current overseas study data and policies. Targeting at the writing part in grade test, the author has collected and organized for 90 students’ writing paper, and analyzed students’ mistakes, pointed out the mistake reasons, and meanwhile revealed the influence of language negative transfer on students. The author has suggested that “metacognitive strategy” should be introduced into writing teaching, and proposed relevant teaching strategies

Exploration of Italian Zero-Based Short-Term Intensive Teaching Model

Based on summarizing domestic and overseas SLA (second language acquisition) theory and Italian zero-based short-term intensive teaching practice, under Web3.0 technical background, this paper has conducted tentative teaching reform of teaching concept, process, technique and teaching management of Italian zero-based short-term intensive education, introduced Production Oriented Approach (POA), to lead the teaching purpose of “help me and let me learn”, integrate “holistic education” into teaching, optimize each procedures of class, and extend students’ learning space and time by means of “flipped classroom”, progressively introduce grammar knowledge points based on language transfer theory, optimize vocabulary and oral English textbook based on the comparative research result between auditory channel input and visual channel input; meanwhile the paper has followed up students’ learning process through teaching practice and conducted comparative research by dividing into experiment group and control group. Based on data analysis, the paper has verified the effect of this Italian teaching model, and proposed prospects for further perfection of future Italian teaching model based on limitations and defects in experiments

Exploration on Italian Language Teaching by “We-Media” in the Mobile Internet Era:Taking "Himalaya FM" App as an example

In the background of the mobile internet era, “We-Media” technologies are changing the traditional information transmission mode. The author chose the online mobile audio sharing platform “Himalaya FM” App that develops the fastest as the carrier, and conducts new exploration into Italian language teaching practices based on the connectivism learning theories, theories of practice, and contradiction theories. According to data analysis between 2014-2018, this paper puts forward Italian language teaching suggestions to further promote more professional, systematic and scientific integration of Italian language teaching and “We-Media” technologies

Semilinear reaction–diffusion systems of several components

AbstractThe homogeneous Dirichlet boundary value problemuit−Δui=∏j=1nujpij,i=1,2,…,nin a bounded domain Ω⊂RN is considered, where pij⩾0(1⩽i,j⩽n) are constants. Denote by I the identity matrix and P=(pij), which is assumed to be irreducible. We find out that whether or not I−P is a so-called M-matrix plays a fundamental role in the blow-up theorems
