This paper reports a laboratorial internship included in the Portuguese Science and Technology promotion program "Internships for Young People in Laboratories (Ciência Viva no Laboratório)", which provided high school students an opportunity to approach the reality of scientific and technological research in a higher education…

In recent years, students' test scores have been used to evaluate teachers' performance. The assumption underlying this practice is that students' test performance reflects teachers' instruction. However, this assumption is generally not empirically tested. In this study, we examine the effect of teachers' instruction on test performance at the…

Chemical stoichiometry is a conceptual framework that encompasses other concepts such as the mole, writing of chemical equations in word and representative form, balancing of equations and the equilibrium concept. The underlying concepts enable students to understand relationships among entities of matter and required amounts for use when…

Educational inequality is a highly debated yet empirically understudied topic in Malaysia. This paper examines the patterns and trends of academic achievement gaps by student social groups in Malaysia, drawing upon nationally representative data for the most recent four cohorts (1999, 2003, 2007, and 2011) of eighth-grade Malaysian students from…

The purpose of this study is to determine the mental models of elementary school students on seasons and to analyze how these models change in terms of grade levels. The study was conducted with 294 students (5th, 6th, 7th and 8th graders) studying in an elementary school of Turkey's Black Sea Region. Qualitative and quantitative data collection…

Improving interest in science, technology, engineering, and mathematics (STEM) is crucial to widening participation and success in STEM studies at the college level. To understand how classroom and extracurricular interventions affect interest, it is necessary to have appropriate measurement tools. We describe the adaptation and revalidation of a…

The purpose of this research is to design assessment instrument to evaluate science generic skill (SGS) achievement and chemistry literacy in ethnoscience-integrated chemistry learning. The steps of tool designing refers to Plomp models including 1) Investigation Phase (Prelimenary Investigation); 2) Designing Phase (Design); 3)…

The purpose of this study is to evaluate two methodological perspectives of test fairness using a national Secondary School Certificate (SSC) examinations. SSC is a suit of multi-subject national qualification tests at Grade 10 level in South Asian countries, such as Bangladesh, India, and Pakistan. Because it is a high-stakes test, the fairness…

The purpose of this study was to provide quantitative data about the effectiveness of the traditional lecture method of teaching in a college science course in contrast with an interactive case study method of teaching and learning. The study investigated one professor's teaching an Advanced Human Anatomy and Physiology course at Nebraska Wesleyan…

The present preliminary research work was intended to measure the scientific attitude, scientific aptitude and scientific knowledge of secondary school students in the selected schools of two districts in Tamilnadu, India. The normative survey method was applied and a total of six null hypotheses(gender, studying class, medium of instruction,…

Learning chemistry is a hard task for many secondary school students; thus, students find it tough to score better marks in chemistry. Researchers have identified many reasons and suggested lots of alternatives to overcome difficulties in chemistry. This paper focuses on whether the test item construction has any role in the response pattern of…

Context-based questions can be effective in reducing test anxiety and increasing science achievement. The purpose of this research was to determine the effects of context-based questions on the test anxiety and science achievement of secondary school students enrolled in a science course, in relation to gender. Seventy students who were found to…

This research was conducted to evaluate the effects of Problem-based Learning (PBL) with Thinking Maps (TM) teaching method (PBL-TM) on Fifth Graders' science critical thinking. The critical thinking skills evaluated were Comparing and Contrasting, Sequencing, and Identifying Cause and Effect in physical science. A quasi-experimental pre-test and…

States are establishing high stakes assessments to serve as measurement tools of students' academic abilities. This study essentially compares Maryland's and Florida's mathematics and science assessments for similarities and differences. Building from 5-10 years of student level quantitative data (secondary data) and critical analyses of the…

We report on the use of bilingual constructed response science assessments in the context of a research and development partnership with secondary school science teachers. Our project provided a series of workshops for teachers where they explored students' emergent reform-oriented science meaning-making in our project-designed assessments. We…
