In this study it was aimed to determine pre-service primary teachers' knowledge structures of fraction through problem posing activities. A total of 90 pre-service primary teachers participated in this study. A problem posing test consisting of two questions was used and the participants were asked to generate as many as problems based on the…

Students often experience difficulty with attaching meaning to mathematics symbols. Many students react to symbols, such as the equal sign, as a command to "do something" or "write an answer" without reflecting upon the proper relational meaning of the equal sign. One method for assessing equal-sign understanding is through…

Engineering-based modeling activities provide a rich source of meaningful situations that capitalize on and extend students' routine learning. By integrating such activities within existing curricula, students better appreciate how their school learning in mathematics and science applies to problems in the outside world. Furthermore, modeling…

Adults' simple arithmetic performance is more efficient when operands are presented in Arabic digit (3 + 5) than in number word (three + five) formats. An explanation provided is that visual familiarity with digits is higher respect to number words. However, most studies have been limited to single-digit addition and multiplication problems. In…

Solving complicated problems in a contemporary knowledge-based society requires higher-order thinking (HOT). The most productive way to encourage development of HOT in students is through use of the Problem-based Learning (PBL) model. This model organizes learning by solving corresponding problems relative to study courses. Students are directed…

Hierarchical cluster analyses were used to detect three subgroups in a sample of children with pervasive developmental disorder--not otherwise specified (PDD-NOS) evaluated at ages 2 and 4. At age 2, Cluster 1 demonstrated few autism symptoms and high cognitive scores; 60% no longer met criteria for PDD at 4. Cluster 2 exhibited more autism…

This article presents "The Two Children Problem," published by Martin Gardner, who wrote a famous and widely-read math puzzle column in the magazine "Scientific American," and a problem presented by puzzler Gary Foshee. This paper explains the paradox of Problems 2 and 3 and many other variations of the theme. Then the authors…

Although daily hassles and coping are associated with behavior and emotional problems in non-clinical populations, few studies have investigated these relationships in individuals with high-functioning autism/Asperger's Disorder (HFASD). This study examined the relationships between daily hassles, coping and behavior and emotional problems in…

This case study contrasts the strategies used by two students in solving bilateral symmetry and reflection tasks, based on the differential properties they attended to. The ninth grader focussed on congruence of sides as the main property of reflection whereas the eighth grader focussed on perpendicularity and equi-distance, as is the normative…

This article introduces the use of public exam questions in fishbowl debate to engage highly exam-oriented secondary students with communicative language teaching (CLT). The practice aims to address the issue that many teachers of English as a second language (ESL)/English as a foreign language (EFL) in Asian contexts either teach to the test or…

Performing the identification of organic chemical compounds from a set of spectroscopic data gives the opportunity to students to develop critical thinking and problem-solving skills. In this context, we developed a student-centered methodology for teaching molecular structural analysis to first-year undergraduate students. This systematic…

This study examined the effectiveness of a school-to-work transition skills program on the career adaptability and career optimism of senior year university students in Turkey. For this purpose, a career intervention program was adapted from one developed in the USA. Results indicated that participants in the intervention group (N = 16) had higher…

This article considers the extent to which the legal framework of Higher Education in the UK (2000- 2010) responded to the needs of the professional work-based student, while in both employment and study. Drawing on Case Law, Education Law and the body of literature on Work-Based Learning (WBL) it discusses the context of the professional student…

The study aimed at assessing Problems of Social Skills in Early Childhood Education Program in Ethiopia. Descriptive survey research design was employed through using stratified random sampling procedure to collect the survey data from 280 teachers recruited from early childhood education programs across three cities: Dire Dewa (130 teachers; 10…

In the online learning environment, it is seen that problems arise in the absence of interaction. In order to prevent these problems, this study, which was carried out by taking into consideration the principles that are formed using the community of inquiry framework, took place during the 2014-2015 Spring Semester using 30 students from a…
