Undergraduate students tend to struggle with probability in their introductory statistics course. Probability problem solving requires several steps. First, students must make sense of the probability scenario, then determine the appropriate probability rules, and finally, execute the procedures to solve the problem. With no previous exposure to probability, this presents too great a cognitive load for many students. Using worked‐out problems then transitioning to partially worked‐out problems in an introductory statistics course at a large university helped students succeed at solving probability problems. The worked‐out problems included writing prompts to encourage self‐explanation of students' thinking through studying the worked‐out examples. This paper explains the use of these instructional principles and their implementation in an introductory statistics course for non‐STEM majors, resulting in higher student achievement and understanding.  相似文献

对初中生学习概率定义的思考   总被引:1,自引:0,他引:1  
了解概率的意义,已成为我国初中数学的教学内容之一,不同的初中数学教材对概率定义的处理方式有所不同.在概率论的历史上,概率的定义经过了古典概率、几何概率、概率的频率定义以及概率的公理化定义.初中生学习概率的意义时,可以将古典概率作为起点,然后引申到几何概率,最后上升到更具有一般性的概率的频率定义。  相似文献

There is much debate about the place of probability in an introductory statistics course. While students may or may not use probability distributions in their post‐collegiate lives, they will likely be faced with day‐to‐day decisions that require a probabilistic assessment of risk and reward. This paper describes an innovative way to teach students in an introductory statistics course how to reason about probability and expected value through the board game Camel Up. The in‐class activities described here can be scaled to fit the needs and abilities of the students in a wide range of introductory statistics courses at a variety of levels.  相似文献

Prior to large experimentations on the teaching of probability theory, it appeared useful to observe some students working for a fairly long time. This observation should make more precise the difficulties of an important aspect when solving probability problems: the modelling aspect. Does systematic use of simulation produce miracles as it is sometimes said? Are the students naturally sensitive to a frequentist approach of probability theory? This paper contains some results on these questions, for example we pointed out for some students an obstacle to the frequentist approach. The results permit to conceive how using simulation for teaching could contribute to an improvement of students' approach to probability.  相似文献

The paper discusses findings of a study that investigated Malawian students' meanings for some probability vocabulary. The study explores the meanings that, prior to instruction, students assign to some words that are commonly used in teaching probability. The aim is to have some insight into the meanings that students bring to the classroom. The sample for the study consisted of 154 students in their first year of secondary school education and whose first language was Chichewa. The paper demonstrates that many of the students' preconceived meanings for probability vocabulary were distant from established conventional probability meanings. In addition, there was a wide range of meanings associated with each of the words. An attempt is made to analyse the students' meanings and to explain their possible sources, some of which are rooted in the students' first language. The paper highlights the importance of having an awareness of students' preconceived meanings, and also stresses the importance of language in learning probability.  相似文献

Summary The day-by-day observations made by the experimenter during one of the activity-based classes indicate that college students can learn to discover some elementary probability models and formulas for themselves while working on probability experiments in small groups. Furthermore, the effects of sample size upon measures of central tendency and variability can be learned by students working on activities such as those developed for the experimental course in this study. Making guesses for the probability of events and checking guesses with a hand-held calculator seems to help college students to be more cautious about probability estimates, and helps to make them aware about some of their own misconceptions about probability. Small-group problem solving, keeping a log of all class work and activities, and investigating the misuses of statistics all appeared to have a positive effect upon college students' attitudes towards mathematics, as indicated in the questionnaires filled out by the subjects in the experimental sections.The present results of this study support the hypotheses of Kahneman and Tversky [10, 12] which claimed that combinatorially naive college students rely upon availability and representativeness to estimate the likelihood of events. Kahneman and Tversky were skeptical about the possibility of helping students to overcome their reliance upon availability and representativeness. The results on the posttest in this study suggest that the manner in which college students learn probability makes a difference in their ability to overcome misconceptions that arise from availability and representativeness. Mere exposure to probability concepts is not sufficient to overcome certain misconceptions of probability. Fischbein [9] notes that the synthesis between the necessary and the possible-which is the basis of probabilistic thinking-does not in fact take place spontaneously .... He claims that science education emphasizes only the deterministic aspect, and neglects the study of uncertainty. Thus peoples' intuition of probabilistic thinking is distorted by science education's emphasis on the necessary, and neglect of the possible. This experiment suggests that the course methodology and the teaching model used in an elementary probability course can help develop peoples' intuition for probabilistic thinking. A course in which students carry out experiments, work through activities to build their own probability models, and discover counting principles for themselves can help students to overcome their misconceptions about probability, and can help restore the synthesis between the necessary and the possible which is essential to probabilistic thinking.  相似文献

The teaching of probability theory has been steadily declining in introductory statistics courses as students have difficulty with handling the rules of probability. In this article, we give a data‐driven approach, based on two‐way tables, which helps students to become familiar with using the usual rules but without the formal structure.  相似文献

We evaluate the impact of Florida's test-based promotion policy on the probability that low-performing students are retained using data on the universe of third-grade students in the state of Florida from 2001 to 2004. We also examine the effect of formal exemptions to the policy on student proficiency in reading two years later. In an evaluation of retention for third-grade students over time with a logit model we find that Florida's policy has increased the probability that minority students are retained to a greater extent than white students. Contrary to previous research, this differential retention occurs after controlling for student academic proficiency. However, in an evaluation of the academic performance of students who were in the first class subject to the retention policy, we find that retained students outperform students who received an exemption from the policy in reading two years after baseline, indicating that on average exemptions have not been granted to those individuals who would benefit from promotion.  相似文献

The employability of university graduates constitutes a major policy concern in both developed and developing nations. In this context, the present study uses self-reported data to compare the earnings and employment expectations of university students, and the realised earnings and employment paths of recent graduates. The sample consisted of 476 individuals (243 students and 233 graduates of the University of Cyprus). The analysis points to both differences and similarities in the effect of different variables on (a) the probability of employment for graduates and the probability of expected employment for students, and (b) the conditional salary of graduates and the conditional expected salary of students. The completion of postgraduate studies, the area of family residence and the department of study are the key factors affecting the graduates’ employment probability, while the students’ probability of expected employment is determined differently, namely by characteristics such as secondary education performance and studies in the business administration department. Gender and family income are among the main determinants of both the graduates’ actual earnings and the students’ expected earnings, with women earning or expecting to earn less than men, and graduates/students with higher family incomes earning or anticipating to earn more than their lower income counterparts. The findings are compared to those of similar studies in other countries.  相似文献

We describe an approach to teaching probability that minimizes the amount of class time spent on the topic while also providing a meaningful (dice‐rolling) activity to get students engaged. The activity, which has a surprising outcome, illustrates the basic ideas of informal probability and how probability is used in statistical inference.  相似文献
