The ability to shoot an effective jump shot in the sport of basketball is critical to a player's success. In an attempt to better understand the aspects related to expert performance, researchers have investigated successful free throws and jump shots of various basketball players and identified movement variables that contribute to their success. The purpose of this study was to complete a systematic review of the scientific literature on the basketball free throw and jump shot for the purpose of revealing the critical components of shooting that coaches, teachers, and players should focus on when teaching, learning, practising, and performing a jump shot. The results of this review are presented in three sections: (a) variables that affect ball trajectory, (b) phases of the jump shot, and (c) additional variables that influence shooting.  相似文献   

Factors and conditions promoting academic resilience: a TIMSS-based analysis of five Asian education systems     

Andrés Sandoval-Hernández  Piotr Białowolski 《Asia Pacific Education Review》2016,17(3):511-520

It is well documented that academic achievement of students from families of low socioeconomic status (SES) tends to be below their more socially advantaged peers. Several studies have identified factors and conditions that facilitate academic success for disadvantaged students (i.e., promote academic resilience). However, one of the main criticisms of this body of research is in the set of variables that explain academic success for low-SES students and which is not very different from the variables that would explain academic success for all students. The objectives of this article are dual: firstly, to identify factors and conditions associated with academic success, regardless of student SES, and secondly, to identify factors and conditions associated with academic resilience, that is, exclusively for low-SES students. To this end, we used data from Singapore, South Korea, Hong Kong, Chinese Taipei, and Japan in the Trends in International Mathematics and Science Study (TIMSS) 2011. The study sample covered 23,354 students in 720 schools in the five countries. The strategy for analysis was driven by fit of logistic regression models, first predicting the probability of academic success and then subsequent identification of variables significant as predictors for success within the pool of low-SES students. Results indicated that variables, such as positive student attitude to mathematics, teacher confidence in student performance and the test language being spoken at home, were associated with greater chances of academic success. High academic expectations and time spent on mathematics at home demonstrated a differential effect between disadvantaged and non-disadvantaged students in Singapore. In Korea, being male (gender) and in Taipei, low levels of bullying at school, increased the likelihood of resilience. Results suggested that interventions impacting behavior reflected in differentially associated variables could help disadvantaged students to become academically resilient.  相似文献

Becoming a guidance counsellor in Ontario: formative influences from counsellors’ perspective     

Daniel Nadon  André Samson  Nicola Gazzola  Anne Thériault 《International Journal for Educational and Vocational Guidance》2016,16(3):363-377

Contrary to guidance counsellors elsewhere in North America who hold a master’s degree, career and guidance counselling services in secondary schools in Ontario are delivered by teachers who have completed additional undergraduate studies. Guidance counsellors are pivotal components of the school as they complete tasks that promote students’ overall development. The aim of this qualitative study was to explore how teachers perceive and describe the process of becoming guidance counsellors in Ontario. The thematic analysis revealed four major themes that articulated the process of becoming a guidance counsellor in Ontario: peer guidance, contextual factors, professional experience, and theoretical knowledge.  相似文献   

Learning and teaching: Differentiation and relation     

Professor Andrée Tiberghien 《Research in Science Education》1997,27(3):359-382

In this paper we discuss the articulation between teaching and learning, how to differentiate them and how to establish relations between them, limiting ourselves to aspects dealing with knowledge. The aim is to allow the design of teaching situations more relevant for learning. The characteristics differentiating teaching and learning are used to analyse research studies relative to two time scales, one of the order of months or years and the other of the order of hours. The comparison shows the importance of the grain size chosen to analyse the knowledge involved both in teaching and in learning. On the first scale, the analysis of the students' knowledge and that of the knowledge to be taught are done independently to the extent that students' knowledge is not analysed in reference to the knowledge to be taught (in terms of error or missing aspect) but on the basis of the student's coherency. The decomposition of these two types of knowledge into similar components allows us to compare them and leads us to propose “intermediate notions” between the usual physics knowledge to be taught and the students prior knowledge. These intermediate notions can be rather far from complete correct physics knowledge but are learnable by the students. On the second scale, detailed analysis of a single teaching session and the students' processes during this session needs a fine level of knowledge granularity. Such a level allows us to make hypotheses based on the elements of students' prior knowledge from which they can construct new knowledge and not only on the prior knowledge which has to be modified. This granularity level allows an emphasis on the positive aspects of students' prior knowledge and enables us to construct hypothesis in order to design teaching situations. Making explicit “intermediate notions” in the knowledge to be taught at a rather large level of granularity of knowledge and the positive aspects of students' prior knowledge at a fine level of granularity, are proposed as ways to improve teaching for fruitful learning.  相似文献   

Impact of Adding Internet Technology on Student Performance and Perception of Autonomy in Fundamentals of Electronics Course     

Carlos Andrés Rosero-Zambrano  Alba Avila  Luz Adriana Osorio  Sandra Aguirre 《Journal of Science Education and Technology》2018,27(2):177-187

The coupling of the traditional classroom instruction and a virtual learning environment (VLE) in an engineering course is critical to stimulating the learning process and to encouraging students to develop competencies outside of the classroom. This can be achieved through planned activities and the use of information and communication technologies (ICTs), resources designed to complement students’ autonomous learning needs. A quantitative analysis of students’ academic performance using final course grades was performed for a fundamentals of electronics course and we examine students’ perception of their autonomy using surveys. The students’ progress and attitudes were monitored over four consecutive semesters. The first began with the design of the intervention and the following three consisted in the implementation. The strategy was focused on the development of course competencies through autonomous learning with ICT tools presented in the VLE. Findings indicate that the students who did the activities in the VLE showed an increase in performance scores in comparison with students who did not do them. The strategy used in this study, which enhanced perceived autonomy, was associated with a positive effect on their learning process. This research shows that a technology-enhanced course supported by ICT activities can both improve academic performance and foster autonomy in students.  相似文献

Community and the myth of the ideal school: Circulation and appropriation of the Hamburg Gemeinschaftsschulen in Spain (1922–1933)     

María del Mar del Pozo Andrés 《Paedagogica Historica: International Journal of the History of Education》2014,50(5):599-614

The progressive education movement was known in Spain from its very inception, and in fact many of its pedagogical theories and practices reached Spain before reaching other European countries. Yet traditional historiography has always maintained that Spain was never integrated in the progressive education movement, a misconception that helps explain the lack of research in the field. Recent historiographical research, however, has shown that numerous Spanish schools served as laboratories for the implementation of progressive education methods in the 1920s and 1930s. The Spanish educational system proved itself to be especially open to international innovation in general and Spain actually enjoyed a privileged position for the study of how innovative pedagogical ideas could be incorporated and appropriated. Proof of this affirmation can be found in the introduction and dissemination throughout Spain of the experimental public school movement of Hamburg known as Gemeinschaftsschulen.

This article will focus on the way this movement was received in Spain. We will examine the phenomenon from a double perspective, corresponding to the different positions that scholars found themselves in within the educational panorama of the time. On the one hand we will examine the role of the “grass-roots” educators who wished to change schools “from below”, starting with classroom practices. On the other hand we will take a look at the representatives of “high pedagogy”, who were intent on formulating a pedagogical theory on which to base a political–ideological model that would serve to change the school “from above”. Tensions arising among the different pedagogical groups, along with the ambiguity of the translation into Spanish of the term Gemeinschaftsschulen, led to the different groups appropriating the concept in different ways. The evolution of the term Gemeinschaftsschulen, from its original identification with a localised school experiment in Hamburg to its becoming a symbol for virtually all European school vanguards, will be addressed at the conclusion of the article.  相似文献   

Sources of difficulty in assessment: example of PISA science items     

Florence Le Hebel  Pascale Montpied  Andrée Tiberghien  Valérie Fontanieu 《International Journal of Science Education》2013,35(4):468-487

ABSTRACT

The understanding of what makes a question difficult is a crucial concern in assessment. To study the difficulty of test questions, we focus on the case of PISA, which assesses to what degree 15-year-old students have acquired knowledge and skills essential for full participation in society. Our research question is to identify PISA science item characteristics that could influence the item’s proficiency level. It is based on an a-priori item analysis and a statistical analysis. Results show that only the cognitive complexity and the format out of the different characteristics of PISA science items determined in our a-priori analysis have an explanatory power on an item’s proficiency levels. The proficiency level cannot be explained by the dependence/independence of the information provided in the unit and/or item introduction and the competence. We conclude that in PISA, it appears possible to anticipate a high proficiency level, that is, students’ low scores for items displaying a high cognitive complexity. In the case of a middle or low cognitive complexity level item, the cognitive complexity level is not sufficient to predict item difficulty. Other characteristics play a crucial role in item difficulty. We discuss anticipating the difficulties in assessment in a broader perspective.  相似文献   

Metacognitive and multimedia support of experiments in inquiry learning for science teacher preparation     

Till Bruckermann  Ellen Aschermann  André Bresges  Kirsten Schlüter 《International Journal of Science Education》2013,35(6):701-722

ABSTRACT

Promoting preservice science teachers’ experimentation competency is required to provide a basis for meaningful learning through experiments in schools. However, preservice teachers show difficulties when experimenting. Previous research revealed that cognitive scaffolding promotes experimentation competency by structuring the learning process, while metacognitive and multimedia support enhance reflection. However, these support measures have not yet been tested in combination. Therefore, we decided to use cognitive scaffolding to support students’ experimental achievements and supplement it by metacognitive and multimedia scaffolds in the experimental groups. Our research question is to what extent supplementing cognitive support by metacognitive and multimedia scaffolding further promotes experimentation competency. The intervention has been applied in a two-factorial design to a two-month experimental course for 63 biology teacher students in their first bachelor year. Pre-post-test measured experimentation competency in a performance assessment. Preservice teachers worked in groups of four. Therefore, measurement took place at group level (N?=?16). Independent observers rated preservice teachers’ group performance qualitatively on a theory-based system of categories. Afterwards, experimentation competency levels led to quantitative frequency analysis. The results reveal differing gains in experimentation competency but contrary to our hypotheses. Implications of combining scaffolding measures on promoting experimentation competency are discussed.  相似文献
