Misconceptions in learning can arise from a variety of sources. This article examines the five sources of misconceptions that may be relevant for understanding learners’ misconceptions in economics classes in junior colleges in Singapore: students’ prior knowledge, their perceptions of what economics is about, their “linguistic mindset”, the influence of student learning preferences, and their perceptions of how graphs are used in economics. Understanding the origin of students’ misconceptions can help junior college teachers anticipate and correct their students’ misconceptions.

Economics teachers often encounter students’ answers that do not make sense or are erroneous explanations of economic phenomena. These answers reveal understanding which is not consistent with generally accepted views or interpretations in economics. How do students’ misconceptions in economics arise?

Tang (2003) proposes that conceptual development is not a simple process of taking in a new conception, and replacing the old with the new because preconditions such as students’ prior knowledge, learning preference and mental model of the subject may interfere with their receptivity to new knowledge and cause students to generate misconceptions. This article considers students’ prior knowledge, their perceptions of economics, the gap between everyday language usage and economic terms, the role of learning preferences, and students’ ideas about the use of graphs in economic analysis as possible reasons for students’ misconceptions in economics.

Introduction
In this preliminary study on the development of pedagogical content knowledge among student teachers in the National Institute of Education, Singapore, Economics and Primary Social Studies student teachers self-report their progress in their professional development upon exit of teacher training using a survey instrument adapted from Ho’s (2003) pedagogical content knowledge development model.

The purpose of this study is to use data on the student teachers’ perceived accumulation of pedagogical content knowledge to throw light on the effectiveness in the teaching areas of Economics and Primary Social Studies in order to better develop pedagogical content knowledge among student teachers.

Pedagogical Content Knowledge
Pedagogical content knowledge is that unique professional understanding that allows teachers to integrate, transform and represent subject matter knowledge in ways that students can understand. Shulman (1987) defined pedagogical content knowledge as

Identify[ing] the distinctive bodies of knowledge for teaching. It represents the blending of content and pedagogy into an understanding of how particular topics, problems or issues are organized, represented, and adapted to the diverse interests and abilities of learners, and presented for instruction. Pedagogical content knowledge is the category most likely to distinguish the understanding of the content specialist from that of pedagogue. (p. 8)

Often, teachers develop their pedagogical content knowledge through their practical experiences. It is therefore important and necessary to provide teachers the opportunities, time, reasons and mechanisms for them to engage in dialogues and discussions that would help them to articulate their pedagogical content knowledge gained from their practical experiences. In essence, it is necessary to assess and measure the development of pedagogical content knowledge. For teacher educators, preliminary findings of how pedagogical content knowledge has been achieved by student teachers would guide in the design and implementation of teacher education for student teachers.
