ADHD (Attention Deficit/Hyperactivity Disorder) is a common neurological disorder that causes a person to have difficulty self-regulating (Daley & Birchwood, 2010a). A child displaying symptoms of ADHD may be impulsive, hyperactive, and/or inattentive, which increases the likelihood of academic failure and behavior difficulties. While symptoms…

The purpose of this study was to determine Turkish primary teacher candidates' conceptual understandings of gases. In this study, a survey approach was used. The sample consisted of 240 primary teacher candidates. As the data collection tool, a questionnaire of six questions consisting of three open-ended and three multiple choice was used. The…

The purpose of this study is to reveal the concept definitions and examples of pre-service elementary mathematics teachers regarding sets. In this context, students' formal definitions, personal definitions and examples in sets were investigated. Concept of equal sets, subsets, union, intersection, compliment, and difference were considered as…

The purpose of this study is to reveal the views and recommendations of the preschool and primary school teachers on the literacy preparation in Turkish preschool education. The study is designed as phenomenological research. The participants of the study are 12 preschool and 9 primary school teachers who have been teaching actively in the western…

Research indicates that a large percentage of students have misconceptions of the equal sign and that this can be detrimental to their mathematical pursuits as they progress through algebra. In order for students to develop a strong understanding of the meaning of the equal sign, algebra teachers must be aware of the viewpoints their students will…

Elementary pre-service teachers in an upper-division algebra mathematics content course explored graphing through the use of Calculator-Based Rangers™ (CBRs). This study explores how they used the "Distance Match" feature of the technology to engage in algebraic thinking. Operating CBR technology, pre-service teachers' perceptions…

Empirical evidence from the National Education Inspectorate suggested that teachers at the primary school in this study in an island country in the Caribbean have inadequate science content knowledge. Students' average performance on the science Grade Six Achievement Test (GSAT) has been below 40% for the last 5 years. The purpose of this bounded…

This paper reports part of an ongoing investigation into aspects of pre-service teachers' geometric knowledge. One hundred and fifty-two Australian pre-service teachers responded to a series of questions that reflect the type of knowledge teachers are expected to know and teach. Analysis of their responses shows that teacher knowledge can be…

Central in the frameworks proposed to capture the knowledge needed for teaching mathematics is the assumption that teachers need more than pure subject-matter knowledge. Validation studies exploring this assumption by recruiting contrasting populations are relatively scarce. Drawing on a sample of 644 Greek-Cypriots preservice and inservice…

This paper describes the structure of the "Air Pollution Course", an environmental science laboratory course developed at the Science Education Laboratory of the Faculty of Primary Education, University of Athens, as well as the findings resulting from its implementation by pre-service elementary teachers. The course proposed in this…

This study examines preservice elementary teachers' (PTs) knowledge for teaching the associative property (AP) of multiplication. Results reveal that PTs hold a common misconception between the AP and commutative property (CP). Most PTs in our sample were unable to use concrete contexts (e.g., pictorial representations and word problems) to…

Formative assessment probes are effective tools for uncovering students' ideas about the various concepts they encounter when learning science. They are used to build a bridge from where the student is in his or her thinking to where he or she needs to be in order to construct and understand the scientific explanation for observed phenomena.…

This study is the part of a larger study on investigating Hong Kong (HK) prospective teachers' (PTs) subject matter knowledge (SMK) and Pedagogical Content Knowledge (PCK). In this paper, five HK PTs' and PC on teaching one topic regarding square root were investigated. The results suggest that insufficient understanding on the concept of…

The purpose of this paper is to engage with the complexities of describing teachers' professional knowledge and eventually also their learning through written tests. The bigger research aim is to describe what knowledge foundation phase teachers acquired during their two years of study towards the Advanced Certificate of Teaching (ACT). We…

The present study sought to reveal how elementary teachers develop their engineering pedagogical content knowledge (PCK) after leaving professional development programs to practice engineering teaching in real classroom settings. Participants of this study were the elementary teachers who received one-week training of engineering education…
