這個研究歸納了小一識字教學期間對學生的觀察，分析小一學生識字的過程及方法。探討現今的中文科教材在識字教學設計上，能否配合漢字的特性，學習者的心理，並提出改進教學設計的建議。 研究的目的是希望從漢字學習、多種識字教學法、兒童心理學的角度來探討學習成效。研究對象是就讀小學一年級的適齡學生。本人選取了大多數學校常用的中國語文科教科書示例，結合實際教學經驗及例子,供教育人士參考。

This paper presents the experimental results of a Soil-Cement Composite Earth Retaining Wall comprised of reinforced concrete underground wall, H-shaped steel beams in earth retaining wall and fiber reinforced soil cement wall. Sixteen specimens are tested to evaluate the bending capacity of the wall. Main variables in the test are strength of concrete, arrangement of shear connector, soil-cement, and fiber reinforcement. Test results are as follows. (1) Composite member under positive moment showed 18% increase of the maximum strength. (2) After soil cement was reinforced with fiber by adding 1% of soil cement weight, compared to cases not reinforced with fiber, strength of under compression increased 7%, moreover, 30% of strength enhancement was shown under tension case also. (3) When the composite member resists positive bending moment (i.e., H-shaped steel beam is in compression), the strength is increased by 18%. Moreover, 7% additional strength enhancement appears after the soil cement is reinforced by fiber. As a results, fiber reinforced soil cement has strength enhancement effect up to 25%.

Restraint to drying shrinkage is the most common cause of concrete cracking. In many applications, drying shrinkage cracks are inevitable. In this paper, the surface cracks of soil concrete caused by drying shrinkage were considered to become an one of concrete textures. So, laboratory shrinkage tests were conducted and the results were applied to the field applications. The study results were summarized as follows; First, the use of vinyl sheets and concrete polymers helped to control the concrete cracking. Second, crack propagation usually started at the interfaces of soil concrete slabs and the cracks grew to the inner slabs. Third, surface cracks of soil concrete slabs could be an one of good concrete textures.

The development of a new type of soil-cement concrete pavement using volcaniclastic is the main purpose of this study. Various mixture ratios, specimens' penetration resistance, time of setting, slump flow of fleshly mixed concrete, compressive strength and color characteristics of hardened concrete were studied. It was concluded that the optimum weight ratio of cement:volcaniclastic to produce good properties of soil-cement concrete is 1:3 and the use of volcaniclastic as main aggregate can improve the concrete surface color that is warm earth-tone road color. Therefore, commercial development for soil-cement concrete pavement using volcaniclastic is highly promising.
