Diagnostic tests have been developed previously to measure algebraic thinking skills; however, the tests do not specifically address algebraic problem-solving. Thus, an Algebraic Thinking Test (ATT) Instrument was developed to measure algebraic thinking skills in problem-solving involving linear equations. ATT comprises nine open-ended questions…

Considering students' voices and perspectives is indispensable in educational contexts. Therefore, instruments of measurement that are reliable and valid and can be used easily without complications are needed in schools.

This study evaluated the construct validity of six scoring traits of an automated writing evaluation (AWE) system called "MI Write." Persuasive essays (N = 100) written by students in grades 7 and 8 were randomized at the sentence-level using a script written with Python's NLTK module. Each persuasive essay was randomized 30 times (n =…

The main aim of this study is to develop a useful, valid, and reliable two-tier proportional reasoning skill test for middle school 7th and 8th-grade students. The research was carried out using the sequential explanatory mixed method. The study group of this research comprised of 391 (n[subscript 7th-grade]=223, n[subscript 8th-grade]=168)…

This study classifies the verbal feedback of science teachers into praise statements, effort-based feedback statements, negative feedback statements, and ability-based statements, which are also regarded as feedback strategies. The study aims to investigate the feedback strategies used by science teachers in the classroom setting using descriptive…

Given the increasing emphasis of communicative competence in English as a foreign language (EFL) contexts and the lack of validation research on speaking assessments for adolescent EFL learners, in the current study we examined the validity of the TOEFL Junior® speaking test, a relatively new speaking assessment developed by Educational Testing…
