The aim of this study is to compare the attitudes of freshman and senior pre-service teachers pursuing an undergraduate degree in an elementary mathematics education program toward teaching profession and to reveal the kind of relationship that exists between these attitudes. Case study method was used in the study. As a data collecting tool, A…

This paper deals with the features and design of explanations in public physics lectures. It presents the findings from a comparative study of three exemplary public physics lectures, given by practicing physicists who are acknowledged as excellent public lecturers. The study uses three different perspectives: the lecture, the lecturer, and the…

Research shows both benefits and challenges of online discussion as a collaborative learning activity. Online discussion is especially challenging for novice college students who have limited metacognitive skills as well as limited knowledge of the subject domain. With limited metacognitive skills, it can be challenging for novice students to…

One of the important challenges for leadership in project teams is the ability to manage the knowledge, communication and coordination related activities of team. In cross-team collaboration, different boundaries contribute to the situated nature of knowledge and hamper the flow of knowledge and prevent shared understanding with those on the other…

Policy problems like "What should we do about global warming?" are ill-defined in large part because we do not agree on a system to represent them the way we agree Algebra problems should be represented by equations. As a first step toward building a policy deliberation tutor, we investigated: (a) whether causal diagrams help students learn to…

The use of effective instructional strategies is clearly emphasized in current educational reform, especially in the area of reading. The purposes of this study were to investigate the rates at which specific instructional practices (i.e., attention signals, prior knowledge supports, previews, instructor modeling, student modeling, organizational…

Four classes of ninth-grade students in an international school in East Asia used a set of web-based technology tools to evaluate two competing webpages about the Taiwan Straits. The findings highlight the ways these students developed disciplinary literacy in social studies by drawing upon cultural resources and contextual knowledge as they…

Animal species identification is often emphasized as a basic prerequisite for an understanding of ecology because ecological interactions are based on interactions between species at least as it is taught on the school level. Therefore, training identification skills or using identification books seems a worthwhile task in biology education, and…

This study examined the effectiveness of worksheets while learning about biodiversity in a natural history museum. Despite the frequent use of worksheets by school classes during out-of-school activities, their effectiveness in enhancing knowledge acquisition has been addressed by relatively few empirical studies. 148 Austrian grammar school…

In this paper we explore the relationship between learning gains, measured through pre-assessment and post-assessment, and engagement in scientific argumentation. In order to do so, this paper examines group discourse and individual learning during the implementation of NASA Classroom of the Future's BioBLAST![R] (BB) software program in a high…

This study investigates the interaction of a group of freshmen enrolled in a Pre Service Physics Teacher Training Course with a mechanics hypermedia program. Data were obtained to discuss hypertextual navigation guided by the following questions: (i) How can the students' navigation in this hypermedia program be characterized? (ii) How does this…

Students need access to the disciplinary practices of engineering, but at the same time, these practices need to transform to the realities of the changing global environment and the profession. The site of this research is an engineering foundation programme for less advantaged students in South Africa and is thus perhaps well-positioned to look…

The purpose of this paper is to report on a usability study for ESL websites conducted to gain insights from learners of English as a second language (ESL) as they interacted with specific sites. Five carefully selected ESL sites were tested by 10 different users generating a total of fifty testing sessions. Two major research questions guided the…

Four experiments investigated classroom learning by deaf college students receiving lectures from instructors signing for themselves or using interpreters. Deaf students' prior content knowledge, scores on postlecture assessments of content learning, and gain scores were compared to those of hearing classmates. Consistent with prior research, deaf…

Do typical arithmetic problems hinder learning of mathematical equivalence? Second and third graders (7-9 years old; N= 80) received lessons on mathematical equivalence either with or without typical arithmetic problems (e.g., 15 + 13 = 28 vs. 28 = 28, respectively). Children then solved math equivalence problems (e.g., 3 + 9 + 5 = 6 + __),…
