Interpreting statistical graphs and making inferences based on the graphs are a precursor for formal statistical inferences. To support student inferences, both teachers and future teachers should have adequate knowledge regarding students' thinking on graphs as well as their potential misinterpretations and difficulties in interpreting graphs. In…

This paper introduces a system that supports student-centered online one-to-one tutoring and evaluates the practical value of the system by running an experiment with 64 experienced mathematics teachers and 810 students in Grade 7. The experiment lasted for 50 days. A comprehensive evaluation was performed using students' academic performance…

This study aims to investigate and compare mathematics teachers' knowledge of pedagogical content, knowledge of students' understanding and knowledge of instructional strategies, subcomponents of pedagogical content knowledge, student errors in the relationship between perimeter and areas in rectangles, squares, and parallelograms. 10…

In recent years, developing students' knowledge integration of specific topics through effective teaching methods has been a concern in science education. This study explored an alternative teaching method, which aims to help lower secondary school students develop their knowledge structure about buoyancy towards a logically integrated conceptual…

The main objective of this study was to compare the effectiveness of three STEM approaches in implementing STEM activities in lower secondary school students based on knowledge and scientific creativity. A pre-posttest experimental design was adapted. Six classes with almost similar learning conditions were randomly selected and each class was…

We investigated the effects of proximal grouping of numbers, problem-solving goals to make 100, and prior knowledge on students' solution strategies in an online mathematics game. Logistic regression on 857 problem-level data points from 227 middle-school students showed that students were more likely to use productive solution strategies on…

Purpose: Guided by the cognitive load theory, the purpose of this study was to determine the impacts of cognitive load and school socioeconomic status-related environmental factors on ninth-graders' energy-balanced living knowledge gain. Methods: A stratified random sample of high-school students (N = 150) participated in this study. Data were…

The aim of this study was to investigate the levels of secondary school students' knowledge about three Global Environmental Problems: Global Warming, Acid Rain, and Ozone Layer Depletion. 638 7th grade (N=316) and 8th grade (N=322) students enrolled in five different secondary schools participated in this study. The survey method was used to…

Knowledge diversity describes group members' differences in terms of prior knowledge in a domain. The purpose of the study was to investigate whether knowledge diversity would impact students' engagement in small-group learning in a science classroom. A total of 45 seventh-grade students were recruited to participate in the study in which two…

Purpose: This study reports on the comparison of students' knowledge about mangrove conservation and their attitude into mangrove ecosystem between students who live in mangrove ecotourism area and those who live outside of mangrove ecotourism area. Methods: About eighty students from public junior high schools located inside mangrove ecotourism…

As climate change becomes an increasingly important topic for science educators, it is critical to learn how teachers may be able to increase students' knowledge about it. We conducted two consecutive quasi-experimental studies that investigated the role of interest in predicting middle school students' knowledge gains from a unit about how…

In this paper we discuss the types of knowledge used by six middle school students as they engaged with a debugging task designed to integrate ideas from computer science, mathematics and science. Our findings show that the computational thinking practice of debugging is a rich source of opportunities to integrate these different disciplines. The…

The relation between prior knowledge and learning has been investigated in many studies. However, a recent meta-analysis showed that most of these studies suffered from serious methodological shortcomings, as they failed to account for knowledge growth over time, possible ceiling effects for learners with high prior knowledge, moderating effects…

Experimentation is a complex problem-solving process. In biology lessons, experiments involve creative thinking and open discovery; however, they still require some degree of instructional guidance. The right balance between discovery learning and instructional guidance depends substantially on students' prior knowledge. Students with low prior…

This study was conducted at a college in Ontario with a sample of students from the Game Development program for 5 intake years: 2014-2018, with the purpose of determining the validity of the Mathematics Diagnostic Test used to place 1st semester college students directly into an advanced math course (Math 10), or to leave them in the introductory…
