Over the past few decades, researchers have focused on the lack of conceptual understanding of mole concept because it is considered to be difficult for students globally. Due to its abstract and mathematical nature, chemistry teachers tend to use algorithmic teaching strategies to provide learning experiences for students, resulting in…

The purpose of this research was to know what the effect of the use of multiple representations (MR) was in the development of the students' cognitive structures. This research was conducted in three Grade 12 classes, in a total of 68 students. A Word Association Test (WAT) was used as data collection instrument. The results from WAT show that…

The aim of this study was to investigate 9th grade biology students' cognitive structures about the basic components of the living organisms and association between the concepts forming these basic components. Participants consisted of 50 9th grade biology students in two secondary schools in the northwest of Turkey. Data were collected by the…

Electromagnetic induction is an important, yet complex, physics topic that is a part of Croatian high school curriculum. Nine Croatian high school students of different abilities in physics were interviewed using six demonstration experiments from electromagnetism (three of them concerned the topic of electromagnetic induction). Students were…

Science education research has revealed a number of student mental models for atomic structure, among which, the one based on Bohr's model seems to be the most dominant. The aim of the current study is to investigate the coherence of these models when students apply them for the explanation of a variety of situations. For this purpose, a set of…

Students often have difficulties understanding abstract physics concepts, such as solid friction. This study examines high school students' mental models of solid friction through a case study of 215 high school students in the ninth through twelfth grades. An achievement test with three open-ended questions was created, with questions limited to…

This paper provides a video-based learning process study that investigates the kinds of mental models of the atmospheric greenhouse effect 13-year-old learners have and how these mental models change with a learning environment, which is optimised in regard to instructional psychology. The objective of this explorative study was to observe and…

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 purpose of this paper is to examine some mathemagenic activities that would transform the internal representations of learners' cognitive structure. The paper pointed out that understanding scientific concept involves the learner's role in translating instructive information into internal representation through the use of some mathemagenic…

Describes an application of methodology based on the Information Integration Theory to study intuitive mastery by 13-14 year-olds of Archimedes' Effect in physics. (Author/YP)

Examined are tenth-grade Western Australian students' conceptual knowledge of gravity and the motion of the planets. Students were interviewed with seven cards, and a four-item diagnostic test based on the interview data on the first four cards was developed. A total of 113 students' responses to the test are summarized. (YP)

The results of survey of secondary school biology students used to access misconceptions about cells are presented. A distinction between conceptions, misconceptions, and nonconceptions is drawn in terms of secondary school biology concepts. The resilience of misconceptions is discussed. (CW)

Describes a study of the understanding of basic electrical concepts shown by 15-17 year-old students in England, France, Netherlands, Sweden, and West Germany. Reports substantially the same pattern of learning difficulties across countries. Provides sample items. (Author/YP)

Reports on a study designed to examine students' understanding of certain aspects of heat, pressure, and evolution. Results indicated that little change was apparent over the two-year period of the study, with most of the students in the 12 to 14 age range at the same conceptual level as the 14 to 16 year olds.

Investigated are the alternative conceptions of the concept "animal" held by African youngsters. Three forms of thinking among the pupils are identified. An attempt is made to explain the possible origin of anthropocentric thinking among pupils. Urban and rural groups are compared. (CW)
