Interval estimation is an important topic, especially in drawing conclusions on an event. Mathematics education students must possess the skill to formulate and use interval estimation. The errors of mathematics education students in formulating wrong interval estimates indicate a low understanding of interval estimation. This study explores the errors of mathematics education students in interpreting the variance in the questions regarding selecting the proper test statistic to formulate the interval estimation of mean accurately. Respondents in this study involved 36 students of mathematics education (N = 9 males, N = 27 females). This research is qualitative research with a qualitative descriptive approach. Data collection was carried out using the respondents’ ability test and interviews. The respondents’ ability test instrument was tested on 36 students and declared valid where r-count r-table with r-table of 0.3291, and declared reliable with a Cronbach Alpha value of 0.876 0.6. Through an exploratory approach, data were analyzed by categorizing, reducing, and interpreting to conclude students' abilities and thinking methods in formulating interval estimation of the mean based on the variance in questions. The results showed that mathematics education students neglected the variance, so they could not determine the test statistics correctly, resulting in error interval estimates. This study provides insight into the thinking methods of mathematics education students on variance in interval estimation problems in the hope of anticipating errors in formulating interval estimation problems.

This article presents a comparison of the proof validation behavior of beginning undergraduate students and research-active mathematicians. Participants' eye movements were recorded as they validated purported proofs. The main findings are that (a) contrary to previous suggestions, mathematicians sometimes appear to disagree about the validity of even short purported proofs; (b) compared with mathematicians, undergraduate students spend proportionately more time focusing on “surface features” of arguments, suggesting that they attend less to logical structure; and (c) compared with undergraduates, mathematicians are more inclined to shift their attention back and forth between consecutive lines of purported proofs, suggesting that they devote more effort to inferring implicit warrants. Pedagogical implications of these results are discussed, taking into account students' apparent difficulties with proof validation and the importance of this activity in both schooland university-level mathematics education.

Campus Activities

As students venture off campus for university-sponsored activities, are they at risk, given that universities are better able to control risk factors on campus than they can for their off-campus activities? Co-operative education is a formalized and longstanding academic program that often sees students spend upwards of a third of their time off campus during the completion of a degree; thus, a discussion of the risks in co-operative education could provide a basis for assessing levels of risk for other off-campus activities. This qualitative, descriptive case study examines co-operative education co-ordinators’ perceptions of the risks to students in co-operative education programs in Canadian universities. Fourteen co-ordinators from across Canada participated in one-on-one interviews. Co-ordinators acknowledged that of the partners in co-operative education, the student is the most at risk. However, they viewed co-operative education as a safe endeavour for students, and there was agreement that the actual risk to students is minimal. The risk factors identified by co-ordinators included personal safety, harassment, youth or limited life experience, and mental health.
