A hybrid triple system of order v and index A, denoted by HTS（v, λ）, is a pair （X,B） where X is a v-set and B is a collection of cyclic triples and transitive triples on X, such that every ordered pair of X belongs to A triples of B. An overlarge set of disjoint HTS（v, λ）, denoted by OLHTS（v, λ）, is a collection {（Y／{y}, .Ai）}i, such that Y is a （v ＋ 1）-set, each （Y／{y}, Ai） is an HTS（v, λ,） and all Ais form a partition of all cyclic triples and transitive triples on Y. In this paper, we shall discuss the existence problem of OLHTS（v, A） and give the following conclusion： there exists an OLHTS（v, λ） if and only if λ= 1, 2, 4, v = 0, 1 （rood 3） and v ≥ 4.

There are six types of triangles： undirected triangle, cyclic triangle, transitive triangle, mixed-1 triangle, mixed-2 triangle and mixed-3 triangle. The triangle-decompositions for the six types of triangles have already been solved. For the first three types of triangles, their large sets have already been solved, and their overlarge sets have been investigated. In this paper, we establish the spectrum of LTi（v,λ）, OLTi（v）（i = 1, 2）, and give the existence of LT3（v, λ） and OLT3（v, λ） with λ even.

In this article, we establish the existence of an LHMTS（mv） for v ≡ 2 （mod 6） and m≡ 3 （mod 6）. Thus there exists an LHMTS（mv） if and only if v（v-1）m2 ≡ 0 （mod 3） except possibly for v=6, m≡ 1, 5 （mod 6） and m≠1. In the similar way, the existence of LHDTS（mv） is completely determined, i.e., there exists an LHDTS（mv） if and only if v（v-1）m2 ≡ 0 （mod 3）.

A directed triple system of order v, denoted by DTS(v, λ), is a pair (X,B) where X is a v-set and B is a collection of transitive triples on X such that every ordered pair of X belongs to λ triples of B. An overlarge set of disjoint DTS(v, λ), denoted by OLDTS(v, λ), is a collection {(Y\{y}, Ai)}i,such that Y is a (v + 1)-set, each (Y\{y}, Ai) is a DTS(v, λ) and all Ai's form a partition of all transitive triples of Y. In this paper, we shall discuss the existence problem of OLDTS(v, λ) and give the following conclusion: there exists an OLDTS(v, λ) if and only if either λ = 1 and v = 0, 1 (mod 3), or λ = 3 and v≠2.

人教版9年级化学教科书关于“二氧化碳熄灭高低蜡烛”实验采用如下方法:往放置高低不同的2支蜡烛的烧杯中倾倒CO_(2)气体,如图1所示。通过“阶梯蜡烛从低到高依次熄灭”的现象,得出CO_(2)具有如下性质:一般情况下,CO_(2)不可燃、不助燃,密度大于空气。按上述操作进行实验存在一些不足。笔者在借鉴同行已有研究的基础上,对该实验进行改进和优化,改进后的实验成功率大大提高。

长期以来,探究性实验一般拘于“目标-教学-评价”的设计逻辑过程,其最大问题是实验的开放度与预期目标难吻合,实验的开放度与实验评价不契合,这些导致探究效果不明显。而基于逆向教学设计的探究性实验,将预期目标与探究的开放性有效融合,探究的目的性更明确,实验的评价也更加具体,效果更明显。以乙酸乙酯制备为例,对比日常探究教学设计和逆向教学设计的流程,重点阐释了遵循“目标-评价-教学”逻辑的逆向教学设计流程。从预估实验结果、注重教学评价、设计表现性任务及开展探究性实验能较好地实现“教-评-学”一体化,有效培养了学生的高阶思维和创新能力。
