A Preliminary Study On The Relationship Between The Quality Of Inquiry And Competitive Hypothesis

A real problem may have more than one solutions. In the activities of problem-solving process what is the difference between two hypothesis and only one hypothesis involved in discussing and exploring? Can teachers set up some counter-examples to promote the students to explore the process? Knowing about these problems can supply certain ideas of designing Inquiry activities ,and also target to train students in scientific thinking, scientific method and scientific spirit and scientific literacy students to truly.In this study, in the way of clinical interview, using "sugar - iodine" research activities by qualitative analysis, to study the relationship between the number of hypothesis and the quality of Inquiry activities in the course of Junior Three students . What's more, I also study the impact to the students of the teachers taking the initiactive counter-examples.Tests include a hypothesis, independent research and the main test to be tested against cases of active stage show. Attempt to study subjects under different assumptions of how the program design exploration activities, how to treat the experimenter presented the counter-examples, and student evaluation of the use of counter-examples to others several aspects of the hypothesis.Found:13.51% of the students can not make any assumptions, 72.97% of the students propose a hypothesis, 13.51% of the students made two assumptions. The vast majority of subjects were focused on assumptions made on the assumption 1, assumption 2, the total number of 45.95%. Were tested under the assumption 1, assumption 2, the activities in the performance of the assumption that a test designed activities were less, averaging 0.70 per person, design activities are concentrated in the 20 level, the total number of 48.65%; In the hypothesis 2, subjects design activities at all levels in the more scattered and no situation is too concentrated, and usually one to be tested on the assumption that the number 2 in the design activity more than an average quantity 0.84 per person, design activities are more abundant. The subjects were also made certain assumptions, the number is relatively dispersed, and were tested on those assumptions less effective program design activities.There is no assumption of the subjects did not reject the hypothesis given in the main trial, test hypotheses in the design of activities demonstrated considerable enthusiasm, but they will also evaluate the assumptions given in the main trial, for they think that a more reasonable assumption is also will actively carry out activities in the design, test hypotheses.Propose a hypothesis to be tested groups, although some assumptions were tested for their activities can not design, but would love to be tested on their own assumptions, and even some of the main test subjects in the activities required by the design assumption that one When a deaf ear to assume a meaning, but according to their own assumptions activities designed to propose a similar situation in the hypothetical subjects in 7 people, accounting for 25.93% of such groups. 6 subjects were made other assumptions, and accept the offer to its main test the hypothesis, but the design of the whole event also includes the shadow of his earlier assumptions, accounting for 22.22% of such groups; the four subjects Although raised their assumptions, however, the design activities and can not convince myself fully satisfied that their Guandian, when the experimenter provided subjects Ling Wai's point of view O'clock, subjects Biaoxian Chu was unwilling to accept some even Jujue right to provide the main trial view of the design activities, accounting for 14.81% of such groups.From the holders of a hypothetical test of the situation by itself is holding an examination of the assumptions during design activities, design activities than those without any assumptions being tested activities designed to enrich, and higher levels. Especially for their very positive assumptions, it is designed to be tested had more activities to prove.Such subjects in the main test questions and then present the two assumptions, however, although some subjects made two assumptions, however, is not on their own two assumptions are very determined, but some of them hypothesis has a higher recognition of the design activities, holding two hypotheses were tested higher levels of design activities to achieve the 30 levels and 2 people to have a more in-depth inquiry.Were tested in the treatment of counter-examples given in the main test areas:Without any assumptions being tested groups, the attitude towards counter-examples focus on regular meeting to refute the main test to see anti-unreasonable assumption given, and, in the main trial and reasonable given the other assumptions were tested will support these counter-examples as evidence of reasonable assumptions; also has a small part of the test subjects were given the main counter-example to show the situation of anxiety or ignored. Put forward a hypothesis to be tested, they were tested in 19 did not give up their original point of view, put forward a hypothesis to be tested accounted for the total number of 70.3%; with six subjects on their own assumptions were revised, accounting for 22.2% of such groups; have a been tested to give up their point of view, accounting for 3.70% of such groups.In holding two hypothetical five were tested in all subjects in the evidence that conflicts with a counterexample, they all gave up one of the assumptions, and selected the counter-examples to support another hypothesis.Finally, the Institute of instruments, interview procedures and objects, data analysis and other aspects of reflection, and in accordance with the results of this study, teachers on the front line to provide some suggestions.
