This paper reports on an interview study of 18 Grade 10-12 students' model-based reasoning of a chemical reaction: the reaction of magnesium and oxygen at the submicro level. It has been proposed that chemical reactions can be conceptualised using two models: (i) the "particle model," in which a reaction is regarded as the simple…

Generalization has been a major focus of curriculum standards and research efforts in mathematics education. While researchers have documented many productive contexts for generalizing and the generalizations students make, less attention has been given to the processes of generalizing. Moreover, there has been less work done with high school…

This study presents a methodology for investigating teacher learning in and from practice based on "discourses" that are in constant flux and transformation. Conceptualizing teacher learning as a frame of meaning based on "knowing" and "doing" discourses, the ideas are illustrated through data collected from a…

The current study explored Mozambican adolescents' perspectives of the process of academic procrastination, focusing on three key aspects: Type of tasks where youth usually procrastinate, antecedents, and the perceived consequences. Twenty-four adolescents from a pool of 300 (11th and 12th graders) reported high levels of procrastination and were…

This study examines changes to Jewish day school students' narratives of the history of Israel after a two-and-a-half-week trip there. Seventeen students were interviewed about the history of Israel before and after the trip. Before the trip, most students' accounts lacked logical connections among the different events. The observations on the…

This paper proposes a model-based notion of "submicro representations of chemical reactions". Based on three structural models of matter (the simple particle model, the atomic model and the free electron model of metals), we suggest there are two major models of reaction in school chemistry curricula: (a) reactions that are simple…

Students' understanding of models in science has been subject to a number of investigations. The instruments the researchers used are suitable for educational research but, due to their complexity, cannot be employed directly by teachers. This article presents forced choice (FC) tasks, which, assembled as a diagnostic instrument, are supposed to…

The quadratic function is an important concept for calculus but the students at high school have many difficulties related to this concept. It is important that the teaching of the quadratic function is realized considering the students' thinking. In this context, the aim of this study conducted through a qualitative case study is to reveal the…

Interdisciplinary teaching is a teaching method that is not as easy as other teaching methods to integrate into the everyday school schedule. This paper serves as an example and gives explanations on how this didactic approach can be applied. The lessons described were conducted successfully with a Year 11 class at a secondary school in which the…

In this paper we explore the role of outdoor residential experiences on the sense of efficacy and examination attainment of a group of under achieving students from socially disadvantaged backgrounds. The article reports on a three year project which focuses on two groups of Year 9 (age 14) to Year 11 (age 16) students. The results reported here…

This article reports the results of an introspective research conducted by a student-teacher and her advisor. Both met regularly over a period of one year and a half as part of the student-teacher academic work for the Research I class. As a result of their conversation the student-teacher and her advisor decided to document the former's…

Most recently, there has been a noticeable rise in the push for use of technology in the classroom. The advancement in digital science has increased greatly the capacity to explore animations, models, and interesting apps. that should substantially enhance science cognition. At the same time, there is a great need to increase collaboration in the…

Student voice is a difficult concept to capture in research. This study attempts to provide a vehicle for understanding student perceptions about writing and writing instruction through a case study supported by discourse analysis of student talk. The high school students in this study participated in interviews and focus groups about their…

Using a mixed methods approach, this study was conducted in Jordanian schools to determine the perceptions of seventh- and eleventh-grade students toward citizenship. Specifically, the study determined what students believe are the attributes of a good citizen, what activities they participate in that are related to good citizenship, and what…

A shortened form of the Career Construction Interview (CCI) was used to help high school students struggling with the career decision making process. The shortened instrument is described, as well as, its use with eleventh grade high school students who had low levels of career concern and career curiosity. Students who completed the exercise…
