本刊讯从中国—东盟博览会秘书处传来消息,11月16-19日,2012年中国—东盟博览会林产品及木制品展(下称“林木展”)将在博览会举办地中国南宁盛大举办。这是在南宁连续第三次举办的林木展。本展会由中国林产工业协会、中国—东盟博览会秘书处和广西壮族自治区林业厅共同承办。届时,中国和东盟国家林木业的政府官员、商界精英和专家学者将再度聚首南宁,为双边林木业的交流与合作奉献一场
The news from the China-ASEAN Expo Secretariat came the news, November 16-19, 2012 China-ASEAN Expo Forest Products and Wood Products Exhibition (hereinafter referred to as “Wood Exhibition ”) will be held at the Fair in Nanning, China Grand hold. This is the third consecutive forest exhibition in Nanning. The exhibition by the China Forest Products Industry Association, China-ASEAN Expo Secretariat and Guangxi Zhuang Autonomous Region Forestry Department co-hosted. By then, government officials, business elites and experts and scholars from the forestry industry of China and ASEAN countries will once again gather in Nanning to dedicate themselves to the exchange and cooperation of the bilateral forestry industry

数学是一门抽象、严密的学科。正由于这一点,令相当一部分学生望而却步,对其缺乏学习热情,产生厌烦情绪。为了提高学生对学习数学的兴趣,提高学生的数学成绩,在数学教学中应当有效利用情境进行教学。 情境教学就是把学生的主动参与具体化在优化的情境中,使其诱发动机,充分感受,主动探究。情境教学当然不能将所有的数学知识都用生活真实形象再现出来。事实上,情境教学的形象真切,并不是实体的复现、忠实的复制或照相式的

我国新一轮课程改革的成败关键在于教学一线的教师如何充分挖掘、利用新教材的这些特征,转变教学观念,优化教学结构,培养学生的各种能力,全面推进素质教育。 1.科学指导学生阅读教材,在预习中自主探索、获取知识。高中数学新教材是一个综合编排的知识体系,知识编排顺序符合高中学生的年龄特征和认知规律,更适合学生自主学习和课前预习。要让学生提前阅读教材,自我探索知识,通过阅读,学生对知识有了一定的理性认识,逐
