Analysis of student’s responses to contradictory results obtained by simple observation or controlling variables

This study investigated students’ responses to presentations of experimental results that conflicted with their preconceptions regarding electric circuits, and how those responses varied according to the type of inquiry skills required to obtain the results. One hundred and twenty students of both sexes were randomly selected from a science high school in Korea. They were questioned about their preconceptions regarding an electric circuit and forty-two students with relevant misconceptions were selected. The students were randomly assigned to two groups, and presented with one of two sheets of paper presenting results obtained by a fictional investigator. The first group was presented with results that were obtained by simple observation and asked for their evaluation of them. The second group was presented with a set of results that were obtained by controlling variables, and asked to draw a conclusion and to evaluate it. Students’ responses were classified into two categories. Some students rejected their own preconceptions and introduced a new explanatory model when contradictory results were presented, and others denied the results for the simple reason that they conflicted with their preconceptions, or only modified a protective belt without changing their core of preconceptions. We found that this distribution of responses varied considerably by inquiry skill type. For the results obtained by controlling variables, almost all students accepted them and changed their preconceptions, but for the results obtained by simple observation, fifty-five percent of students preserved their own preconceptions by denying the contradictory results or modifying the protective belt.     

Inclusive Education in China: Conceptualisation and Realisation

This paper examines the historical background of the development of special education and how “Learning in Regular Classrooms” (LRC) has become the major service delivery model to universalise compulsory education for children with disabilities in China. The authors assert that the current model of inclusive education in China was conceptualised through the influence of the Western ideology of inclusion and the practical consideration of Chinese socio-economical conditions. To realise this model, a number of strategies were introduced and widely practised in an attempt to effectively implement the LRC programs. Adverse social climate, the exam-oriented education system, and limited resources in all aspects, however, remained as critical elements to be overcome for the future development of inclusive education in China. The LRC model is expected to continue to be the main form of inclusive education in China.     

Learning to compose digitally: the effect of prior computer use and keyboard activity on NAEP writing

Writing is critical for college and career readiness, yet secondary students in America are not good writers (National Center for Education Statistics, 2012). Unfortunately, researchers know relatively little about secondary students’ writing skills, and even less about their digital writing. In this study, we explored prior computer use, keyboard activity during writing, and their relations to writing achievement using the 8th grade 2011 National Assessment of Educational Progress writing assessment, the first national computer-based writing assessment for U.S. secondary students. We found that prior computer use predicted students’ writing skills directly (0.08) and indirectly (e.g., keypresses, 0.14) via keyboard activity during the test. We found differential effects for certain groups including current English learners and disadvantaged students. We also found a small positive interaction effect of prior use and keypresses on writing. That is, the benefits of prior computer use for school writing and the value of students’ additional keypresses on writing achievement were amplified when both were present.
