General chemistry is often the first course taken by students interested in careers in STEM and health fields, and therefore, is considered an essential course for the success and retention of students in these fields. Prior studies have shown study habits and skills to be related to student performance in college-level courses, including STEM…

This study was conducted to examine the achievements of students in the concepts of light and shadow measured in different assessment formats according to the learning style and gender. In this study, correlational survey model was used. The sample consisted of 10th grade (16 years) high school students (n=815) from different types of six high…

In this research an instrument was developed to measure students' anxiety about the jargon of physics. Levels of anxiety were then compared with student content performance and general classroom anxiety. Anxiety levels were also compared based on students' language of origin (native vs. nonnative English speaking students). Statistical analyses…

Learners underperform in stoichiometry as they lack conceptual reasoning of the underlying concepts and the ability to solve stoichiometric problems. Therefore, it was necessary to determine if there is a statistical correlation between problem-solving skills and conceptual reasoning in stoichiometry and if so, whether one can significantly…

Concept inventory (CI) tests are typically used to measure students' general knowledge before and after instruction. We find issue with the current format of these tests, which some researchers claim, measure students' misconceptions, since the answers choices given to students do not consider their prior knowledge. We particularly analyze Force…

This paper evaluates the use of peer and self-assessments as part of the learning process of an open ended, essay-based course in a second-year degree engineering module in Brunei Darussalam. The essays were marked using a rubric by the student, a peer, and the lecturer, with students being pre-trained on the use of the rubric prior to the…

In this study, it was aimed to determine the levels of the ability of science teaching fourth grade students to transfer their knowledge of astronomy and space sciences to daily life within the scope of the Astronomy and Space Sciences lesson. For this purpose, the research method was designed as the mixed method including both the quantitative…

We measured the personality type of the students in a large introductory physics course of mostly life science students using the True Colors instrument. We found large correlations of personality type with performance on the precourse Force Concept Inventory (FCI), both term tests, the postcourse FCI, and the final examination. We also saw…

We present the Electricity and Magnetism Conceptual Assessment (EMCA), a new assessment aligned with second-semester introductory physics courses. Topics covered include electrostatics, electric fields, circuits, magnetism, and induction. We have two motives for writing a new assessment. First, we find other assessments such as the Brief…

This study investigates the effects of problem-based learning (PBL) on students' academic achievements in studying "Electrochemistry" within a course on Analytical Chemistry. The research was of a pretest-posttest control group quasi-experimental design and it was conducted with second year students in the Chemistry Teaching Program at…

This study makes an important contribution to an expanding body of international comparative studies by exploring factors predicting differences in science and mathematics achievement by students in Turkey and the Republic of Korea on the 2011 TIMSS assessment. While these countries are similar with regards to population size, cultural beliefs…

In this study, the effect of the context-based approach on pre-service primary school teachers' understanding of matter and its states and their attitude towards chemistry was investigated. Using a simple experimental design, the study was conducted with 35 pre-service primary school teachers who were exposed to context-based material with…

This is the start of a road map for the effective introduction of inquiry-based learning in chemistry. Advantages of inquiry-based approaches to the development of scientific literacy are widely discussed in the literature. However, unless chemistry educators take account of teachers' reservations and identified disadvantages such approaches will…

Through in-class observations of teaching assistants (TAs) and students in the lab sections of a large introductory physics course, we study which TA behaviors can be used to predict student engagement and, in turn, how this engagement relates to learning. For the TAs, we record data to determine how they adhere to and deliver the lesson plan and…

The researchers wanted to continue in their university's previous study of nature awareness and science achievement, specifically examining the effects of nature in the achievement of seventh-grade students. This further study offered valuable insight to the inconclusive findings of previous researchers of nature awareness and science achievement.…
