Abstract. Test validation based on usual statistical analyses is paradoxical, as, from a falsificationist perspective, they do not test that test data are ordinal measurements, and, from the ethical perspective, they do not justify the use of test scores. This paper (i) proposes some basic definitions, where measurement is a special case of scientific explanation; starting from the examples of memory accuracy and suicidality as scored by two widely used clinical tests/questionnaires. Moreover, it shows (ii) how to elicit the logic of the observable test events underlying the test scores, and (iii) how the measurability of the target theoretical quantities – memory accuracy and suicidality – can and should be tested at the respondent scale as opposed to the scale of aggregates of respondents. (iv) Criterion-related validity is revisited to stress that invoking the explanative power of test data should draw attention on counterexamples instead of statistical summarization. (v) Finally, it is argued that the justification of the use of test scores in specific settings should be part of the test validation task, because, as tests specialists, psychologists are responsible for proposing their tests for social uses.

This research is intended to know the effectiveness of quantum reading model by printing media with yen basis in reading concept learning to students of grade 4th elementary school. The problems are: profile of students reading concept competences, the learning process of reading concept, the learning process of reading concept by quantum reading model by printing media with yen basis, the effectiveness of quantum reading model by printing media with yen basis in reading concept learning, and students response of quantum reading model by printing media with yen basis.The trouble-shooting is by use quantum reading model by printing media with yen basis by assumption: if students need to do something therefore will be easily to motivate them in learning and get a better result.Population in this research is Grade 4th Students of elementary school at Sumber Regency, Cirebon. The sample is determined by purposive sampling. The objects in this research are quantum reading model by printing media with yen basis and students reading concept competences. Instruments in this research are sheets of questionnaire, sheets of learning observation, and reading concept competence test. Data that are collected are learning process and data of students reading concept competences. Collected data are analyzed by descriptive statistic analyze.Result of this research are: (1) the competences of students reading concept are good, (2) the learning process are done with students actively, (3) quantum reading model by printing media with yen basis can increase students activity and learning result, (4) quantum reading model by printing media with yen basis is effective to use in reading concept learning, and (5) the students response to reading concept learning by use quantum reading model by printing media with yen basis is very good.Base on the result of this research, get to be proposed for teacher to use quantum reading model by printing media with yen basis to increase students reading concept competence as one of alternative technique in learning, because it is able to motivate, grow the students interest, and increase students creativities to increase students reading concept competences.
