The questions in the practice assignments given to students in the form of worksheets or other formats are often grouped by chapter, topic, or concepts. There is a great emphasis on categorization. Most of the end-of-chapter problems in chemistry textbooks are organized by sections. Although this was done with the intention of helping students…

The present study explores students' understanding of calculus-based kinematics (henceforth, CBK), in which argumentation is taken as the sequence of the modes of fostering reasoning and problem-solving. The investigation stresses the importance of arguments students bring to the learning situation of CBK and recognizes the active construction of…

This paper extends prior work establishing an operationalized framework of mathematical sense making (MSM) in physics. The framework differentiates between the object being understood (either physical or mathematical) and various tools (physical or mathematical) used to mediate the sense-making process. This results in four modes of MSM that can…

One desired outcome of introductory physics instruction is that students will develop facility with reasoning quantitatively about physical phenomena. Little research has been done regarding how students develop the algebraic concepts and skills involved in reasoning productively about physics quantities, which is different from either…

This study aims to identify the effect of STEM practices, integrated into Science courses in 6th grades of middle schools, on students' academic achievement, problem-solving skills, their attitudes towards STEM, and their interest level of STEM fields. The population of the study consists of 6th -grade students enrolled in a middles school in the…

Jim Greer and his colleagues argued that student modelling is essential to provide adaptive instruction in tutoring systems and showed that effective modelling is possible, despite being enormously challenging. Student modelling plays a prominent role in many intelligent tutoring systems (ITSs) that address problem-solving domains. However,…

Computational thinking (CT) is a problem-solving process and argued to be one of the more important skills for the 21st century. This study aimed to identify the effectiveness of the Science Module on achievement in science subjects. A quasi-experimental research design was used that involved 67 students in the first form in secondary schools…

This study aims to investigate the effects of authentic learning methods -- applied in science courses -- on the problem-solving skills and attitudes towards those courses. As a research design, a quasi-experimental design with pre-test and post-test control groups was used in the study. The data of the study were collected from 92 students at the…

Background: It is widely known that for many students it is very difficult to correctly predict how thermal expansion affects the appearance of a metal plate with a circular hole. Interviews with school teachers show that the source of this difficulty could stem from the fact that students' internal visualizations of an arbitrary object's thermal…

This study examined effects of the Polya's problem solving Technique (POPSOT) as observed by Shaibu (1987) in Atadoga (2010) and conventional problem-solving Technique (CONPSOT) on cognitive achievement of physics students. A pre-test post-test quasi experimental design used adopted for the study. The sample comprised of 102 senior secondary two…

This paper is a follow-up to a previous study, in which students (predominately life science majors) were found to self-express achievement goals with regard to a pre-lab problem-solving exercise in an algebra-based introductory physics course. In this paper, the same sampled population was also asked in the same feedback survey to discuss what…

This study mainly aims to determine the effect of layered curriculum on problem solving skills of students in science and technology course. The study group of the research is the 6th grade students of an elementary school in the center of Malatya. The mixed method, which includes quantitative and qualitative research patterns, was used. In the…

Computational thinking (CT) is one of the systematic tools in problem solving and widely accepted as an important skill in the 21st century. This study aimed to identify the effectiveness of the Chemistry Computational Thinking (CT-CHEM) Module on achievement in chemistry. This study also employed a quasi-experimental design with the participation…

One of the fundamental problems for the college students is not being able to solve the multi-concept physics problems. The reason is that the problem solving strategies is limited to known-asked strategy (traditional strategy).Though this strategy can only be used to solve the problems of mono-concept physics. Therefore, this research on the use…

The application of factor analysis to the "Force Concept Inventory" (FCI) has proven to be problematic. Some studies have suggested that factor analysis of test results serves as a helpful tool in assessing the recognition of Newtonian concepts by students. Other work has produced at best ambiguous results. For the FCI administered as a…
