This study evaluates the experimental tasks of the Ethiopian grade 12 chemistry textbook vis-à-vis coverage of the essential components of science process skills (SPSs) using content analysis. All the procedures in an experiment were analyzed using rubrics of the inquiry-based task analysis inventory (ITAI) instrument. This instrument was based on…

In this study, high school physics textbooks published by People's Education Press (PEP) and Educational Science Publishing House (ESP) (a total of 6 books) in China were analyzed via a self-developed scale measuring nature of science (NOS) including three first-level indicators of scientific knowledge, scientific process, and scientific…

According to (inter)national policy and curriculum documents, the acquisition of research skills is an important objective of secondary education. However, the conceptualization and hence the operationalization of this concept seems ambiguous. Furthermore, no test exists to assess students' proficiency in (a broad range of) research skills in a…

This study enhanced the 7E instructional model towards enriching the science inquiry skills of senior high school learners in General Chemistry 1. A total of 136 Grade 12 learners enrolled in the Science, Technology, Engineering, and Mathematics (STEM) strand participated in the study. The study was composed of three phases. In Phase I, the…

This article describes the results of a study into students' experiences of independent research project work in science. Independent research projects are projects in which students are supervised (usually by a teacher, scientist or both) to work independently on a scientific problem or question over an extended period. We collected data from 39…

Research studies that deal with student ability to investigate and carry out inquiry oriented investigations often call for educational practitioners to pay particular attention to incorporating the skills of scientific inquiry in the process of teaching and learning. This has the aim of helping learners acquire the skills needed to become problem…

Inquiry learning is a widely recognized method for fostering inquiry competence in science education. Nevertheless, there is discussion about how to best support students while working on inquiry tasks (in this case: experiments on causal relationships). To identify the kind of support students need in order to design experiments in upper grades,…

This study aimed to develop the small-scale experiments involving electrochemistry and the galvanic cell model kit featuring the sub-microscopic level. The small-scale experiments in conjunction with the model kit were implemented based on the 5E inquiry learning approach to enhance students' conceptual understanding of electrochemistry. The…

The aim of this study is to compare and contrast the science process skills (SPS) included in the 10th-12th grade physics textbooks content utilized in Yemeni schools. The study revealed weaknesses and strengths in the textbooks' content. For instance, a number of science process skills (SPS), such as measuring, predicting and hypothesizing, have…

The educational reform movement since the 1990s has led the secondary earth science curriculum in Taiwan into a stage of reshaping. The present study investigated secondary earth science teachers' perceptions on the Goals of Earth Science Education (GESE). The GESE should express the statements of philosophy and purpose toward which educators…

The case-based computerized laboratory (CCL) is a chemistry learning environment that integrates computerized experiments with emphasis on scientific inquiry and comprehension of case studies. The research objective was to investigate chemical understanding and graphing skills of high school honors students via bidirectional visual and textual…

This study reports on the teaching of life sciences (biology) to blind and visually impaired learners in South Africa at 11 special schools with specific reference to the development of science process skills in outcomes-based classrooms. Individual structured interviews were conducted with nine science educators teaching at the different special…

Our main goal in this study was to explore whether the use of models in molecular genetics instruction in high school can contribute to students' understanding of concepts and processes in genetics. Three comparable groups of 11th and 12th graders participated: The control group (116 students) was taught in the traditional lecture format, while…

The 2012 edition of the "Digest of Education Statistics" is the 48th in a series of publications initiated in 1962. The "Digest" has been issued annually except for combined editions for the years 1977-78, 1983-84, and 1985-86. Its primary purpose is to provide a compilation of statistical information covering the broad field…
