Strategy use,listening problems,and motivation of high- and low-proficiency Chinese listeners

Building on previous listening strategy research, the author aimed to explore the differences between Chinese high-proficiency listeners (HLs) and low-proficiency listeners (LLs) on their strategy use, problems, and motivation in native language (L1) listening. It involved 1,290 Grade 7 and 1,515 Grade 9 students. Both quantitative and qualitative methods, including a listening comprehension test, questionnaires, and interviews, were adopted. The findings indicated that HLs possessed more types of strategies and used strategies more frequently and effectively than LLs. HLs not only reported fewer listening problems but also had a better awareness of listening problems and use of problem-solving strategies than LLs. Both HLs and LLs agreed with the importance of listening but showed little interest in doing listening tasks. The similarities and differences between the findings of this study and those of second-language listening research and implications for planning effective instruction to enhance native language listening proficiency are discussed.

Research on Educational Media: Half a Century of Doing Things Right Rather Than the Right Thing

This paper critically examines research on the influence of educational media on learning. It argues that much of the supposed benefits of media such as greater concreteness, improved learning performance, more efficient learning and increased retention, among others, are not supported by the evidence thus far. Comparative research on different forms of media, and on media attributes have likewise proved inconclusive. The paper goes on to explore reasons for these findings and urges that future studies should focus on studies with media rather than on media.
