Since two of our International Advisers - Prof. Huanan Liang and Mr. Anthony K.H. Tong have retired, it is our honours to have Prof. Chao-Ti Hsiung (Normal Taipei Teachers' College) and Mr. Chee-kuen Yip (Chief Curator of the Hong Kong Science Museum) accepted our invitation to join us as new inernational advisers.  Besides, Dr. Jingling Liu who is the Head of the Environmental Science Department, Northeast Normal University becomes another Guest Editor of our Editorial Board.
   
    In the Second Issue of Volume Two, we are very glad to have our new International Adviser, Mr. Chee-kuen YIP to write for our Foreword section an article in both Chinese and English on the primary science activities based on the ancient Chinese astronomy exhibition held at the Hong Kong Science Museum. In the Academic Articles section, we got four research papers on a wide and popular areas of science education, to wit  "assessment of interdisciplinary tasks" (by May CHENG and Winnie SO), "effective science teaching and learning in Australia" (by Russell TYTLER), "scientific literacy for student teachers (Winnie SO and May CHENG) and "enhancing  science teachers' creativity" (by Vivian CHENG). Apart from those peer-reviewed research papers, we have four pieces of general articles written by some science educators, school teachers, or  educational researchers. They are related to the "group work implementation in Hong Kong" (by Simmi TAM), "group work in science learning" (by Teresa WONG), " scientific investigation as a creative teaching method in primary education" (by Alex TSE) and "the environmental education in China" (by Jingling LIU and Eric TSANG). Besides, there is one set of multimedia resources on "making apparatus for demonstrating breathing mechanism and smoking process" (edited by Man-tak CHAN) which contains 36 pieces of video clips (with different resolution quality) available for downloading.  Files of all those articles are available for retrieval in the Adobe Portable Document Format (pdf) and furthermore there are the Simplified Chinese version (in GB coding) for all Chinese articles.
