The research reported here consists of the introduction of an intervention based on a series of laboratory activities combined with concept mapping. The purpose of this intervention was to enhance student understanding of acid-base chemistry for tenth grade students' from two classes in a Turkish high school. An additional aim was to enhance…

School science systems tend to emphasize teaching and learning about achievements of science (such as laws and theories) at the expense of providing students with opportunities to develop realistic conceptions about science and science inquiry and expertise they could use to conduct their own science inquiry projects. Among reasons for such an…

This study developed, validated, and utilized the Technology Integrated Classroom Inventory (TICI) to examine technology-integrated science learning environments as perceived by secondary school students and teachers. Using technology-oriented classroom climate instruments and considering the science classroom's characteristics, TICI was…

A survey instrument was developed and administered to 1,222 K-12 mathematics and science teachers to measure their beliefs about and use of inquiry in the classroom. Four variables (grade level taught, content area taught, level of support received, and self-efficacy for teaching inquiry) were significantly correlated to two dependent variables,…

A new learning unit in chemistry, "Case-based Computerized Laboratories" (CCL) and Computerized Molecular Modeling" (CMM) was developed at the Technion. The CCL and CMM curriculum integrates computerized desktop experiments and molecular modeling with an emphasis on scientific inquiry and case studies. Our research aimed at…

Thinking Journey is introduced as a mode of science instruction based on a specially designed discussion between students and teachers in the context of an imaginary journey. The paper elaborates the rationale of this mode and its specific features: enculturation into science, analytical observation, multiple perspectives of the subject and…

Science teachers generally find inquiry-based laboratory work very difficult to manage. This research project aimed at facilitating chemistry teachers to implement inquiry-based laboratory work in Hong Kong secondary schools. The major concerns of seven chemistry teachers were identified. They were most concerned about the lack of class time,…

This paper presents the results of a case study involving 282 Taiwanese elementary science teachers at the elementary level. These teachers provided responses to the science efficacy instrument (STEBI-A) and also provided personal data regarding how their years of general (YTE) and science (YTS) teaching experience may have influenced student…

We describe research carried out with a prospective secondary biology teacher, whom we shall call Miguel. The teacher's conceptions of the nature of science and of learning and teaching science were analyzed and compared with his classroom practice when teaching science lessons. The data gathering procedures were interviews analyzed by means of…

This study has resulted in an elementary science methods course that facilitates the identification and description of the changes in students' conceptions and understanding of inquiry teaching, and the cultural influences, reflections, and situational factors influencing these changes. Written responses to open-ended questions, reflective…

In order to develop successful teaching approaches to transformations of matter, we need to know more about how young students develop an understanding of these processes. In this longitudinal study, we followed 25 students from 7 to 13 years of age in their reasoning about transformations of matter. The questions addressed included how the…

The research reported in this case study explores the understanding of stoichiometry and related concepts of Thai science students in grades 10 and 11 after major national curriculum reforms. Students' conceptions and alternative conceptions were investigated using a questionnaire--the "Stoichiometry Concept Questionnaire" (SCQ) (N =…

The study described in this article is based on a long-term comprehensive series of investigations that were conducted in the context of teaching high school chemistry in the laboratory using inquiry-type experiments. The students that study chemistry according to this program are involved in an inquiry process that included all the inquiry skills…

The purpose of this study was to evaluate the instructional effects of using animations, static figures, PowerPoint bulletins, and e-plus software as chemistry texts with the aid of computer-based technology. This study analyzed the characteristics of students involved in three multimedia courses and their achievement and attitude toward chemistry…

There is, no doubt, untapped potential in using technological tools to enhance the understanding of science concepts. This study examines the potential by observing 7th and 8th grade middle school students' (n=23) use of portable data collection devices in a nine-week elective class, "Exploring Technologies". Students' use of the data collection…
