According to the first, learning difficulties are due to the intrinsic characteristics of the student. For supporters of the second perspective, those difficulties result from the interaction between the student and the school system. The objective of this study is to test the validity of these two perspectives in interpreting learning difficulties in mathematics among at-risk students. To this end, we collaborated with normally achieving （undiagnosed） and at-risk students. Results show that the second perspective is better suited to the interpretation of learning difficulties in mathematics students展开更多

Prusiner＇s theory. Knot theory in mathematics is useful in studying a topological difference of topological objects. In this article, concerning this conjecture, a topological model of prion proteins （PrPc, PrPsc） called a prion-tangle is introduced to discuss a question of whether or not the prion proteins are easily entangled by an approach from the mathematical knot theory. It is noted that any prion-string with trivial loop which is a topological model of a prion protein can not be entangled topologically unless a certain restriction such as ＂Rotaxsane Property＂ is imposed on it. Nevertheless, it is shown that any two split prion-tangles can be changed by a one-crossing change into a non-split prion-tangle with the given prion-tangles contained while some attentions are paid to the loop systems. The proof is made by a mathematical argument on knot theory of spatial graphs. This means that the question above is answered affirmatively in this topological model of prion-tangles. Next, a question of what is the simplest topological situation of the non-split prion-tangles is considered. By a mathematical argument, it is determined for every n 〉 1 that the minimal crossing number of n-string non-split prion-tangles is 2n or 2n-2, respectively, according to whether or not the assumption that the loop system is a trivial link is counted.展开更多

Given the differences in different periods of higher mathematics learning objects, as well as students learning content in different periods and in different conditions, teachers in the teaching mode of teaching could be considered stage of teaching. That is, different content based on various stages of teaching and student learning, and use different teaching methods and means to carry out teaching.展开更多

Digital course environment promotes the teaching interest and becomes the learning under the support of learning terminal, which must make students happy. The digitalization of teaching materials, platform of learning and learning according to requirements promotes the establishment of happy class. Establishment of learning environment is the basis of realizing the reform of learning and teaching ways. With the rapid development of information technology, intelligence learning is the necessary outcome of deep integration with education learning.展开更多

Evidence from young children suggests that trajectories of number learning differ for children having different home numeracy experiences. Children involved in higher frequency of direct numeracy practice tend to have higher numeracy skills, but the result becomes more complicated when considering the types of home numeracy activities. The relationship between the home numeracy experience and preschool children＇s nurneracy development may shed light on how children acquire number skills and develop their mathematics competence.展开更多

The current study was carried out through the quantitative research method. The research question to be addressed is：During the first two years of college English learning, does non-English majors＇ learning motivation （i.e. types of motivation and motivational intensity） change？ The analyses of the data reveal that motivational changes do exist in the first two years of college English learning. Generally, most types of motivation （i.e. intrinsic interest motivation, information medium motivation, personal development motivation, and social responsibility motivation） decrease significantly except for the slight increase of immediate achievement motivation, and the decline of motivational intensity is also obvious.展开更多

By analyzing the lead author, research institute, high frequency keywords, highly cited literature etc., this paper discovers the core topics, research hotspots and frontiers in recent years and the new forms of ecoliterature, the change of international frontier, the new opportunities of ecoliterature research are found. The paper presents a direct view of the study on ecoliterature both in China and abroad. In the end, this paper offers guiding and expectation to Chinese scholars with regard to future research.展开更多

One of the challenges of this learning format is that students must develop strategies to practice on their own between lessons, iSCORE can help meet that challenge by supporting students as they develop strategies for self-regulation to enhance their goal-setting, practice strategies, and abilities to reflect and critique their progress. This paper describes a case study of a 15-year-old pianist who learned to play a difficult piece of repertoire by using iSCORE to archive and compare performances, develop strategies, and reflect on his learning.展开更多
