Prior studies in the Computer Science education literature have illustrated that novices make many mistakes in composing SQL queries. Query formulation proves to be difficult for students. Only recently, some headway was made towards understanding why SQL leads to so many mistakes, by uncovering student misconceptions. In this article, we shed new…

Our civilization recognizes that errors can be valuable learning opportunities, but for decades, they have widely been avoided or, at best, allowed to occur as serendipitous accidents. The present research tested whether greater learning success could paradoxically be achieved through making errors by intentional design, relative to traditional…

This study investigated the role of the bar model method, a significant aspect of the Singapore mathematics curriculum, in the remediation of seventh-grade students' errors on algebra word problems. To accomplish this purpose, we first assessed students' errors on a written test involving algebra problems and identified ten students based on the…

Conventional graded assignments are commonly structured in a format where students attempt a prescribed question and are graded based on the completeness of their workings rather than the understanding of concepts. An alternative assignment format was proposed which requires students to identify and explain mistakes in a given set of workings…

In this study, ways in which 9-year old students from one Singapore school solved 1-step and 2-step word problems based on the three semantic structures were examined. The students' work and diagrams provided insights into the range of errors in word problem solving for 1- step and 2-step word problems. In particular, the errors provided some…

In this study we set out to investigate the errors made by students in logarithms. A test with 16 items was administered to 89 Secondary three students (Year 9). The errors made by the students were categorized using four categories from a framework by Movshovitz-Hadar, Zaslavsky, and Inbar (1987). It was found that students in the top third were…

The present study examined the influence of Singapore Colloquial English (SCE) on Standard English word spelling through a plural formation task of four words ("man", "tooth", "dress" and "child") among 168 Singaporean bilingual children with Chinese background. It was found that "dropping the…

This paper reports on students' errors in performing integration of rational functions, a topic of calculus in the pre-university mathematics classrooms. Generally the errors could be classified as those due to the students' weak algebraic concepts and their lack of understanding of the concept of integration. With the students' inability to link…

Reports on a partial replication of a Bardovi-Harlig and Dornyei (1998) study that used a videotaped judgment task to test informants' degree of awareness f pragmatic inappropriateness and grammatical errors. The study is carried out with English-as-a-Foreign-Language learners from the People's Republic of China and English-as-a-Second-Language…

Illustrates the schematic approach to analyzing children's (n=499) errors in solving mathematical problems using children's written solutions. Identifies five levels of errors: no solution, using irrelevant procedure, incomplete schema with no errors, incomplete schema with errors, and complete schema with errors.
